Before JOHNSON, JOLLY, and JONES, Circuit Judges.
EDITH H. JONES, Circuit Judge:
Fifteen years ago Engineering Dynamics, Inc. (EDI)
successfully defended itself against claims that its computer
program infringed registered copyrights held by Synercom
Technology, Inc. on Synercom's user manuals and input formats.
That case held that neither the input formats brought to the
court's attention nor their sequence and organization were
copyrightable. Synercom Technology, Inc. v. University Computing
Co., 462 F. Supp. 1003 (N.D. Tex. 1978). EDI has now switched sides
and seeks a judgment of copyright infringement against Structural
Software, Inc. (SSI), a competitor who copied many of EDI's input
and output formats. The parties primarily differ over the district
court's holding that computer input and output formats are not
copyrightable and hence cannot infringe a copyright directly or as
a derivative work. See district court opinion at
785 F. Supp. 576,
582 (E.D.La. 1991).
This opinion examines the extent of copyright and trade
dress law protection of computer/user interfaces and user manuals.
We reverse the district court's holding that computer/user
interface in the forms of input and output formats are
uncopyrightable and reverse and remand to determine whether there
was infringement. We affirm the court's other rulings.
BACKGROUND
In 1970, Synercom brought to market a computer program
called STRAN, designed to solve engineering problems in the field
of structural analysis. The program required the user to "input"
a large amount of data, including construction details and
anticipated environmental and other external forces that would act
upon the structure. The computer program performed numerous
tedious calculations using accepted engineering principles to
generate output which facilitated the design and construction of
the structure.
In 1975, EDI entered the market with its computer
program, SACS II,1 which utilized precisely the same input formats
and input sequence as Synercom's STRAN program. Both SACS and
STRAN were run only on mainframe computers. Part of EDI's
1
There was never a SACS I. The acronym stands for structural
analysis computer system.
2
marketing strategy was to stress the complete compatibility of SACS
with STRAN's input formats, entered into the computer via decks of
80-column keypunch cards. Synercom, 462 F. Supp. at 1008, 1012.
Synercom had obtained thirteen copyright registrations covering
nine input formats and sued EDI for infringement. Then-district
judge Higginbotham ruled that the formats of the keypunch cards, as
well as their sequence and organization, were not copyrightable,
thus relieving EDI of any liability for format infringement. Judge
Higginbotham also held, however, that EDI had infringed Synercom's
copyright in its user manuals. As part of a resulting settlement
agreement, EDI prepared a new edition of its user manual, SACS III,
which did not infringe Synercom's copyright.
Over the years, EDI refined SACS III and its input
formats to accommodate users' desire for greater speed,
flexibility, and ease of operation. After many piecemeal
revisions, EDI changed the name of its program to SACS IV. Despite
the fact that actual paper keypunch cards are rarely used anymore,
EDI has retained the 80-column data input format. Most users now
enter data as image files and store the data on a magnetic storage
device, e.g., a floppy disk. The 80-column card format is familiar
to relevant users of these programs, thus facilitating training and
allowing them to reevaluate old data decks. This opinion follows
industry practice and uses the terms "input format" and "card"
interchangeably.
The SACS IV input formats instruct the user to place
specific kinds of information in a specific place on the card. The
3
first five columns or so are reserved for identification of the
card by its name, e.g., WAVE. The parties' versions of this card
are reproduced in the appendix hereto. Subsequent columns of
various widths are reserved to enter instructive and descriptive
data. The WAVE card, for example, is used to calculate ocean wave
forces on structures built offshore. Several columns allow the
user to instruct the computer as to which wave scenario (load case)
is to be generated and by what wave theory. Much of the data
entered describes conditions and parameters needed to generate
hypothetical wave forces, e.g., the waves' size, frequency, and
direction. The placement of the required information on the proper
card and in the proper columns is crucial to obtaining correct
results. Other input formats instruct or describe many other
structural and environmental factors.
EDI's structural analysis program is actually a "suite"
of 23 semi-autonomous modules, each created to facilitate certain
aspects of structural analysis. Each module is designed to
interact with other modules of the suite, for example, by
preprocessing certain data, then feeding it to another module. One
module called SEASTATE generates and calculates the environmental
effects on an offshore structure. This is an important module
because most EDI customers use SACS for designing offshore
structures, such as drilling platforms. Another module called
JOINTCAN is used to design the "joint cans" which connect tubular
members of a structure, taking into account various stresses,
tolerances, and construction techniques. The heart of the SACS
4
suite is a module itself called SACS. This module processes,
through the computer, user-supplied environmental and design data
and calculates the static and dynamic forces within and upon each
component of the structure. A large quantity of output data is
then organized and printed in a systematic fashion that facilitates
further engineering or construction efforts, e.g., showing the
kinds and quantities of forces to which each component of the
structure is subject.
EDI has not copyrighted any of the actual computer
programs comprising the SACS suite, i.e., the source code and
object code. Instead, it has chosen to protect itself by
maintaining the program as an unpublished trade secret via
confidentiality contracts with users and other security techniques.
It has, however, obtained four copyright registrations covering the
user manuals for three of the 23 modules: SACS III, SACS IV,
SEASTATE, and JOINTCAN. The SACS suite of programs allegedly
specifies over 200 input formats. The four copyrighted user
manuals describe 51 formats (excluding nonformatted cards such as
header cards and end cards), most of them pertinent to SACS III2
and SEASTATE.
In 1986, Rao Guntur began developing a similar structural
analysis program targeted at the offshore platform market that
could be used on a personal computer. Guntur's company, Structural
Software, Inc. (SSI), began marketing his program, StruCAD*3D, that

The SACS IV user manual was apparently not offered as evidence and
is not found intact in the record on appeal. It is apparently not much
different from SACS III for purposes relevant to this appeal, however.
5
same year. EDI brought its PC version to market a short time
later. Although built on a different public-domain structural
analysis program, StruCAD borrowed heavily from the SACS user
interface. Like SACS, data entry for StruCAD is based on an 80-
column format. As was the case when EDI copied Synercom's input
format and sequence, many of StruCAD's potential customers were
already familiar with EDI's interface; SSI wanted to minimize
required training for these users and facilitate conversion of SACS
input data files to StruCAD's formats. StruCAD utilizes 126 input
formats.
EDI's allegations in the instant case differ in three
important respects from Synercom's allegations in 1978. First, the
decks of computer keypunch cards prepared for use in Synercom's
program STRAN were completely compatible with SACS II when it was
introduced. In the instant case, many individual data cards
completed for use in SACS would require some, but not extensive,
modification before they could be run in StruCAD. Second, StruCAD
requires dozens of input formats completely different from those
found in SACS III or SACS IV. Third, while only nine input formats
were alleged to have been copied in Synercom, and the copyright
registrations on each of the nine were at issue, EDI does not claim
protection for any of its individual input formats and output
reports. Instead, it contends that the sequence and organization
of formats and reports is as a whole copyrightable.
EDI brought suit against SSI and against Guntur in his
individual capacity, claiming that they copied 56 of EDI's input
6
formats. To support its claim, EDI assembled numerous exhibits
highlighting the similarities between the alleged infringing
formats. A close examination of the WAVE input format description,
for example, (see Appendix) reveals that both programs' cards
require precisely the same information in precisely the same data
columns, except that StruCAD requires that columns 5-8 and 31-38 be
left blank while in SACS these columns are optional. (But note
that SACS also requires that 31-38 be left blank if columns 25-30
are used.) In addition to the infringement claim based on input
formats, EDI alleges copying of output report formats, copying of
EDI's user manuals for use in the StruCAD manual, and copying of
portions of EDI's user manuals for use on StruCAD's "help screens."
EDI also brought unfair competition claims against SSI, alleging
violations of section 43(a) of the Lanham Act and La. Rev. Stat.
Ann. § 51:1405(A).
Guntur and SSI (hereinafter often jointly referred to as
SSI) admit that Guntur copied EDI material when he developed
StruCAD. SSI argues, however, that input formats are not
copyrightable in the first instance. Moreover, SSI asserts that
EDI appropriated many of these formats from Synercom's STRAN
program and contends that EDI cannot now claim a proprietary
interest in something that it copied from Synercom. Appellees
raise various other defenses to the other copyright and unfair
competition claims that are addressed in the analysis below.
After a four-day bench trial, the district court
dismissed EDI's claims against Guntur in his individual capacity
7
and dismissed all copyright claims involving StruCAD's input and
output formats. The district court agreed, however, that StruCAD's
user manual infringed EDI's copyright in its SACS manuals and
ordered SSI to pay EDI $250,000 in actual damages. The district
court also enjoined SSI from any further marketing of StruCAD until
the parties agreed on a noninfringing manual for StruCAD. The
parties were unable to reach an agreement on a new noninfringing
manual, leading the district court to appoint a special master to
decide whether SSI's new manual still infringed. After reviewing
the manuals and briefs prepared by both parties, the special master
concluded that SSI's new manual did not infringe any of EDI's
copyrights. The recommendations and findings of the special master
were adopted by the district court the same day they were received.
This opinion will address the appealed issues in the
following order:
I. Copyrightability of input/output formats and
user interfaces;
II. The scope of copyright protection for user
interfaces;
III. User manual infringement;
IV. Help-screen infringement;
V. Objections to the Special Master's report and
procedures;
VI. Rao Guntur's liability in his individual
capacity;
VII. Trade dress infringement and unfair
competition; and
VIII. Calculation of damages.

I. COPYRIGHTABILITY OF
INPUT/OUTPUT FORMATS AND USER INTERFACES
EDI has registered copyrights in four user manuals
containing detailed verbal descriptions and pictorial
representations of input and output formats. EDI contends that SSI
and Guntur infringed EDI's copyrights by copying a portion of its
user manuals -- the input and output formats -- and incorporating
them into the StruCAD user manual and into StruCAD's user
interface. This, EDI maintains, is either direct unlawful copying
under 17 U.S.C. § 106(1) or unlawful preparation of a derivative
work under 17 U.S.C. § 106(2).
To establish copyright infringement, a plaintiff must
prove ownership of a valid copyright and copying of constituent
elements of the work that are copyrightable. Feist Publications,
Inc. v. Rural Tel. Service Co., 499 U.S. 340, 361,
111 S. Ct. 1282,
1296 (1991). Copyright ownership is shown by proof of originality
and copyrightability in the work as a whole and by compliance with
applicable statutory formalities.3 Plains Cotton Coop. Ass'n. v.
Goodpasture Computer Serv., Inc.,
807 F.2d 1256, 1260 (5th Cir.),
cert. denied,
484 U.S. 821 (1987). Two separate components
underlie proof of actionable copying. First is the factual
question whether the alleged infringer actually used the
copyrighted material to create his own work. Copying as a factual
matter typically may be inferred from proof of access to the

manuals and input formats and output reports reproduced therein.

copyrighted work and "probative similarity."4 Plains Cotton, 807
F.2d at 1260. Not all copying, however, is copyright infringement.
Feist, 499 U.S. at 361, 111 S.Ct. at 1296. The second and usually
more difficult question is whether the copying is legally
actionable. This requires a court to determine whether there is
substantial similarity between the two works. Plains
Cotton, 807
F.2d at 1260.
On appeal, SSI does not contest the validity of EDI's
ownership in the four copyrighted user manuals as a whole. Nor is
copying as a factual matter disputed; Guntur candidly testified
that he used EDI's formats when developing StruCAD. Instead, SSI
raises several contentions. First, SSI asserts that under this
court's Plains Cotton decision, which allegedly approved the
Synercom district court decision, user input formats are not
copyrightable as a matter of law. SSI elaborates upon this
argument by pointing out that nine of the formats found
uncopyrightable in Synercom are nevertheless alleged by EDI here to
be protected. Second, SSI asserts that EDI's computer input and
output formats represent unoriginal facts and lists of facts that
are not copyrightable and thus are not subject to infringement.
Third, SSI contends that the SACS IV input and output formats
represent an uncopyrightable idea, process or method. EDI
4
Professor Latman distinguishes between "probative similarity,"
which relates to factual copying, and "substantial similarity," which relates
to actionable copying. See 3 Melville B. & David Nimmer, Nimmer on Copyright
§ 13.01[B] (1993) (hereinafter Nimmer); see also Gates Rubber Co. v. Bando
Chemical Indus., Ltd., 9 F.3d 823, 832 (10th Cir. 1993) (adopting same
terminology).
10
distinguishes the instant case from Synercom and responds that its
input and output formats, at least when taken as a whole, are
copyrightable. EDI further argues that SSI has infringed EDI's
copyright by SSI's "massive appropriation of plaintiff's expression
at the interface."
This inquiry represents a subset of the general questions
surrounding computer program copyrightability. Some of the issues
in this novel and complex area of law are slowly being resolved.
Congress has declared that computer programs are in principle
entitled to copyright protection.5 That decision largely overcame,
though it does not fully answer, one major statutory exception to
copyrightability, the "useful article" exception.6 Most courts
confronted with the issue have determined that copyright protection
extends not only to the literal elements of a program, i.e., its
source code and object code,7 but also to its "nonliteral"
elements, such as the program architecture, "structure, sequence
and organization", operational modules, and computer-user
interface. See, e.g., Computer Assocs. Int'l, Inc. v. Altai, Inc.,
5
A computer program is "a set of statements or instructions to be
used directly or indirectly in a computer in order to bring about a certain
result." 17 U.S.C. § 101.
6
In no case does copyright protection for an original
work of authorship extend to any idea, procedure,
process, system, method of operation, concept,
principle, or discovery, regardless of the form in
which it is described, explained, illustrated, or
embodied in such work.
17 U.S.C. § 102(b).
7
Source code is the programming language readable by human
programmers; object code is the binary expression that controls the computer
hardware.

9 F.3d 823 (10th Cir. 1993); Lotus Development Corp. v.
Paperback Software Int'l,
740 F. Supp. 37 (D.Mass. 1990) (Lotus I).
But as one moves away from the literal code to more general levels
of a program, it becomes more difficult to distinguish between
unprotectible ideas, processes, methods or functions, on one hand,
and copyrightable expression on the other. Lotus
I, 740 F. Supp. at
53. Court decisions are, generously described, in a state of
creative ferment concerning the methods by which nonliteral
elements of computer programs may be identified and analyzed for
copyrightability.8
Until recently, it could be argued that Fifth Circuit
precedent precluded recognition of the copyrightability of
nonliteral elements of computer programs. This argument was based
on the Plains Cotton case, an alleged Fifth Circuit endorsement of
the district court decision in Synercom. Synercom, decided before
Congress passed the 1980 amendments to the Copyright Act, held that
80-column data cards, developed for an early species of punch-card
computers, represented an uncopyrightable process or idea because
they could not be divorced from their mode of expression. SSI and
the district court interpreted Plains Cotton broadly as adopting
Synercom. That Plains Cotton did not actually do so has now been
settled by this court in Kepner-Tregoe, Inc. v. Leadership Software
8
Compare the approaches used by the courts in Whelan Assocs., Inc.
v. Jaslow Dental Lab., Inc., 797 F.2d 1222 (3d Cir. 1986), cert. denied,
479
U.S. 1031 (1987); Altai, supra; Lotus
I, supra; Brown Bag Software v. Symantec
Corp.,
960 F.2d 1465 (9th Cir.), cert. denied,
1135 S. Ct. 198 (1992); etc.
12
Inc., 12 F.3d 527 (5th Cir. 1994). Kepner-Tregoe embraced the
"general, noncontroversial proposition that nonliteral aspects of
copyrighted works -- like structure, sequence and
organization -- may be protected under copyright law . .
." 12
F.3d at 536, n.20. Thus, SSI benefits from no synergy with
Synercom.9
But SSI also makes a more particular argument based on
Synercom. Because Synercom declared that particular input formats
integral to SACS IV's predecessor program (STRAN) were
noncopyrightable ideas, SSI contends, the same must be true of
those formats descended from STRAN. We disagree. In Synercom, the
plaintiff sought copyright protection for individual input formats;
here, EDI makes a different claim that several dozen input formats
taken together form a copyrightable work, because they represent
but one of many ways of expressing a mode of computerized
structural analysis. This general point renders Synercom
distinguishable.
The holding in Kepner-Tregoe resolves only one level of
controversy between the parties, albeit the level on which the
district court rested his decision. After Kepner-Tregoe, one must
conclude that nonliteral elements of computer programs may be
copyrightable in the Fifth Circuit, but not that they are
9
SSI contends that we should not analyze the input formats as
nonliteral elements because that analysis depends on the existence of a
copyright on the underlying program. We reject this argument. It makes no
difference to the formats' copyrightability whether we analyze them as
springing from a computer program or from a user manual.
13
necessarily copyrightable in this case. To that issue we must
turn.
II. SCOPE OF COPYRIGHT
PROTECTION FOR USER INTERFACES
Two qualifications on this discussion must be noted.
Because of the factual content of many of these issues, it is
expedient to remand to the district court, which conducted a full-
scale trial, to reconsider his decision according to the principles
about to be explained. The judge's interpretation of Synercom, a
decision by which he believed he was bound, rendered a close
factual analysis unnecessary. Second, this is not a case in which
the outer limits of copyright protection for computer-user
interface need be explored. The input and output formats for SACS
IV are quasi-textual; while they guide the user in performing a
series of sophisticated structural analyses, they consist of a
series of words and a framework of instructions that act as prompts
for the insertion of relevant data. In some computer programs, the
user interface may merge almost wholly with the expression,
processes, or ideas embodied in the program -- voice-activated or
virtual reality programs or those attuned to the human heartbeat
furnish some examples that may trouble courts in the future. We do
not presume to anticipate the legal consequences of such
technological developments.
The analysis below focuses, as did the parties in their
briefs, on the copyrightability of EDI's input formats. There is
no intuitive reason why the analysis should be any different for
output formats. Indeed, in some cases it may be difficult to
14
classify a given interface as one or the other. Clearly,
therefore, some output formats will contain sufficient original
expression to merit protection. Cf. Broderbund Software, Inc. v.
Unison World, Inc., 648 F. Supp. 1127 (N.D. Cal. 1986) (interface of
program which generated customized greeting cards copyrightable).
Generally, we endorse the abstraction-filtration-
comparison method of determining copyright protection for computer
programs, which has been ably elucidated by the Tenth Circuit in
Gates Rubber, 9 F.3d 823, 834 (10th Cir. 1993). The court
summarized this method as follows:
First, in order to provide a framework
for analysis, we conclude that a court should
dissect the program according to its varying
levels of generality as provided in the
abstractions test. Second, poised with this
framework, the court should examine each level
of abstraction in order to filter out those
elements of the program which are
unprotectable. Filtration should eliminate
from comparison the unprotectable elements of
ideas, processes, facts, public domain
information, merger material, scenes a faire
material, and other unprotectable elements
suggested by the particular facts of the
program under examination. Third, the court
should then compare the remaining protectable
elements with the allegedly infringing program
to determine whether the defendants have
misappropriated substantial elements of the
plaintiff's program.
It is unnecessary here to reproduce the Gates Rubber court's
thoughtful explanations of the various components of this approach.
See also discussions in Altai, 982 F.2d at 706-11; 3 Nimmer,
§ 13.03[F] (advocating much the same test as "successive
filtering"). We shall apply that methodology to the parties'
arguments in order to provide guidance and to narrow the issues on
15
remand. The abstraction-filtration-comparison method was developed
in cases dealing with the copyrightability of parts of computer
programs other than user interface. Judge Keeton, however,
employed a similar systematic approach to the Lotus user interface
cases. See Lotus I, supra; Lotus Development Corp. v. Borland
Int'l, Inc., 788 F.Supp 78 (D. Mass. 1992)(Lotus II); etc.
Describing this approach as abstraction-filtration-comparison
should not convey a deceptive air of certitude about the outcome of
any particular computer copyright case. Protectible originality
can manifest itself in many ways, so the analytic approach may need
to be varied to accommodate each case's facts. See
Altai, 982 F.2d
at 706 (three-step test can and should be modified when computer
technology demands it); Gates
Rubber, 9 F.3d at 834, n.12 (same).
Given that caveat, we adopt the Gates Rubber/Altai/Nimmer method to
consider EDI's user interface, input formats and output reports.
A. Abstraction
The purpose of segmenting a computer program into
successive levels of generality is to "help a court separate ideas
[and processes] from expression and eliminate from the substantial
similarity analysis those portions of the work that are not
eligible for copyright protection." 3 Nimmer, § 13.03[F] at
13-102.17.
Judge Learned Hand first penned the abstraction method to
analyze the elements of a literary work to distinguish between
protectible expression and abstract unprotectible ideas. Nichols v.
Universal Pictures Corp., 45 F.2d 119, 121 (2d Cir. 1930), cert.
16
denied, 282 U.S. 902 (1931). Analogizing his formula to computer
programs, at each level of abstraction into which the program can
be segmented, the court determines whether the contents of that
segment depict an idea, process or method, which, inseparable from
its expression or incapable of expression by any other means, is
therefore uncopyrightable.10
Abstraction of ideas from expression does not pose a
particular conceptual hurdle in this case for three reasons.
First, EDI seeks copyright protection not of its entire suite of
SACS programs but only of approximately 230 input-output formats
that comprise the user interface. The user interface is
analytically distinct from other parts of the program. See
Ogilvie, supra note 10, 19 Mich. L. Rev. at 542 n. 73. Second, EDI
claimed protection of input and output formats not individually but
en masse. It is thus unnecessary to decide whether each individual
input format card or output format report represents an idea or an
expression.
10
The abstraction method makes good sense intuitively, but its
application to computer programs has been problematic. A particular source of
difficulty has been definitional -- how to describe the levels of generality
ascending in computer programs from the literal code to the most general
"idea" of the program itself. Case law has approached the definitional
problem inconsistently. One author, while criticizing the courts' diverse and
halting efforts at using the abstraction method, suggests that the levels of
abstraction can be conformed to six technical component norms recognized among
computer programmers. See John W. L. Ogilvie, Note, Defining Computer Program
Parts under Lerned Hand's Abstraction Test in Software Copyright Infringement
Cases, 91 Mich. L. Rev. 526 (1992). His proposed levels of abstraction, in
descending order, are: the main purpose, system architecture, abstract data
types, algorithms and data structures, source code, and object code.
Ogilvie's levels of abstraction have already been approved by one circuit
court. Gates Rubber Co.,
9 F.3d 835. Ogilvie's levels of abstraction do not
directly apply to the present case, however, because his note does not deal
with user interfaces.
17
Third, the formats, taken as a whole, readily qualify as
"expression" measured against the ideas versus expression
dichotomy. Not all user interfaces will so easily pass that test.
The purpose of the SACS input formats is to mediate between the
user and the program, identifying what information is essential and
how it must be ordered to make the program work. The output
formats structure the results of calculations performed by the
program informatively for the user. These formats do not self-
evidently convey only an "idea."
Because of the functional quality of user interface, the
abstraction portion of the three-step methodology may pose
difficult questions. A user interface may often shade into the
"blank form" that epitomizes an uncopyrightable idea, Baker v.
Selden, 101 U.S. 99 (1880),11 or it can partake of high expression,
like that found in some computerized video games. In the middle of
the abstraction spectrum sit user interfaces such as that of Lotus
11
This approach is consistent with the Supreme Court's analysis in
Feist, where the Court required "some minimal degree of creativity," or a
"minimal creative spark" before finding copyrightability in a compilation of a
telephone book's white pages. 499 U.S. at 362,
363, 111 S. Ct. at 1296, 1297.
More than trivial originality is necessary, however. This approach is
consistent with the great majority of blank-form cases decided in other
circuits. See Harper House, Inc. v. Thomas Nelson, Inc.,
889 F.2d 197 (9th
Cir. 1989) (compilation of blank forms in executive organizer copyrightable,
but individual blank diary forms not protectible); Cash Dividend Check Corp.
v. Davis,
247 F.2d 458 (9th Cir. 1957) (finding copyrightability of check with
accompanying text describing a stamped-check plan to convert savings stamps
into cash); Brown Instrument Co. v. Warner,
161 F.2d 910 (D.C. Cir. 1947)
(graphic temperature-pressure charts designed to record not copyrightable);
Taylor Instrument Co. v. Fawley-Brost Co.,
139 F.2d 98 (7th Cir. 1943), cert.
denied,
321 U.S. 785 (1944) (blank form for recording temperatures not
copyrightable); see also Harcourt, Brace & World, Inc. v. Graphic Controls
Corp.,
329 F. Supp. 517 (S.D.N.Y. 1971) (finding copyrightability of optically
scanned answer sheet forms which provided spaces for indicating correct
answers, but which also conveyed certain minimal information). Blank forms
that are designed merely to record information rather than convey it are not
copyrightable. See generally 1 Nimmer, § 2.18[B].

numerous expressive features. See Lotus I, 740 F. Supp. at 65-68.
As Judge Keeton put it, if a best-selling program's interface were
not copyrightable, competitors would be free to emulate the popular
interface exactly so long as the underlying programs were not
substantially similar. This cannot be the law.
The scientific, technical character of the SACS IV
program distinguishes it in certain respects from the open-ended,
user-directed spreadsheet user interface found copyrightable in
Lotus I. But on this initial level of abstraction analysis, it is
certain that there are numerous ways in which either input or
output formats could have been structured in order to achieve the
program's purpose. Consequently, it is appropriate to proceed
further in considering the copyright protection available to EDI
for its input formats and output reports.
B. Filtration
The filtration component of the analysis seeks to isolate
noncopyrightable elements from each particular level of a program.
Copyright protects the expression of ideas, not the ideas
themselves, and it does not protect processes, methods or
scientific discoveries. Other materials not subject to copyright
include facts, information in the public domain, and scenes a
faire, i.e., expressions that are standard, stock or common to a
particular subject matter or are dictated by external factors. See
Gates Rubber, 9 F.3d at 837-38. Each of these limitations upon
copyright or defenses against illicit copying follows logically
19
from the purpose of the Copyright Act: to protect an author's
original, creative expression insofar as is compatible with general
advancement of expressive arts and "the free use and development of
non-protectable ideas and processes." Altai, 982 F.2d at 711.
SSI forcefully advances several of these concepts in
defense of the copying it engaged in to produce StruCAD. SSI
contends that EDI's user interface comprises unoriginal facts,
which are not copyrightable. It asserts that the data formats are
merely a template that enables an engineer to use his tool, the
computer. SSI also denies that EDI's "compilation" of input/output
formats is copyrightable. Finally, SSI contends that EDI's user
interface depends so heavily on engineering industry standards and
practice that it is unprotectible under the scenes a faire
doctrine.
1. Unprotectible Facts versus Original Expression
SSI describes the input/output data formats as "garden
variety documentation that merely presents column-by-column formats
of input data and describes the information . . . to be stored in
each column, pictures, figures or diagrams, which merely elucidate
basic engineering and mathematical relationships." Therefore,
according to SSI, the input/output formats fail to satisfy the
Feist-Zack Meyer originality test. In Feist, the Supreme Court
held that an alphabetically arranged phonebook lacks the creativity
and originality necessary to sustain a copyright. In Donald v.
Zack Meyer's T.V. Sales and Service, 426 F.2d 1027 (5th Cir. 1970)
(the Zack Meyer case), this circuit held that boilerplate
20
contractual language printed on a blank form was insufficiently
original.
As a comparison with the facts of Feist and Zack Meyer
makes obvious, SSI's argument is simplistic in the present context.
Certainly, one may isolate each individual input requirement or
series of requirements and contend that it is merely shorthand for
a common engineering formula. Likewise, abbreviations for terms,
dictated by necessity or industry standard, are uncopyrightable by
themselves. What appears on EDI's input and output formats,
however, are not any kind of formulas or "facts" as such, but
organized, descriptive tables for entry of data on which the
computer will perform necessary calculations. "Facts" are entered
by the user and "factual" algorithms are applied by the computer,
but the appearance and expression of the user interface are not
themselves a representation of "facts." SSI does not assert that
there is only one way or a limited number of ways in which such
tables may be or are usually set forth. Given the complexity of
offshore design projects, it is hardly surprising that a number of
other competing structural design programs exist in the market, and
the trial court found them dissimilar to SACS. As a matter of law,
the input formats and output reports do not embody only
noncopyrightable "facts."
2. Input Formats as a Template, Process or Method
Because the input data formats are organized in a
particular fashion to effectuate the performance of mathematical
calculations, SSI likens them to a template or tool used by the
21
engineer. We assume this argument relies on Baker v. Selden, 101
U.S. 99 (1880), although SSI has not cited that seminal case.
Baker rejected a claim of copyright on a book that described a
method of bookkeeping. Moreover, the author's ledger sheets were
held not copyrightable because they were necessary incidents to the
idea or process embodied in the bookkeeping method. Like Baker v.
Selden, whether one denominates the input formats in this case as
a process or as expression "merged" with a process, the demarcation
between their utilitarian and expressive aspects is difficult to
draw. Compare
Altai, 982 F.2d at 712;
Synercom, 462 F. Supp. at
1013-14.
The difficulty may best be illustrated by comparing this
case with those concerning infringement of the Lotus 1-2-3
spreadsheet program. The Lotus program enables a user to create
documents adapted to his particular needs in a framework that may
be varied and that may utilize different types of information. As
the district court held in Lotus I, the command format and sequence
structure in an original word processing or computer spreadsheet
should be copyrightable because as a whole, the interface's
structure and hierarchy constitute a high degree of original
expression. See Lotus I, 740 F. Supp. at 65-68.
The SACS input cards, in contrast, perform only one,
admittedly challenging task: they supply engineering data for
offshore structures. The question is whether the utilitarian
function of the input formats, which ultimately act like switches
in the electrical circuits of the program, outweigh their
22
expressive purpose so as to preclude copyright protection. On
balance, we believe they do not. EDI's input formats as a whole
convey substantial information regarding what data the user needs
to gather and how they should be organized for the program to run
properly. One of EDI's trial witnesses testified that the
interface "imparts knowledge" by telling the user which data to
collect as well as the order of collection. This alone does not
necessarily mean that SACS imparts knowledge through protectible
expression. But, generally, functional interfaces that directly
teach or guide the user's independent decisions are more expressive
than functional interfaces that lack these qualities. Although the
degree of interaction may not be as high as that present in Lotus,
overall, EDI has proved original expressive content in the
selection, sequence and coordination of inputs.
3. EDI's User Interface as a "Compilation" of "Facts"
SSI analogizes the copyrightability of the SACS input
formats and output reports to the copyrightability of compilations
as addressed in Feist Publications, Inc. v. Rural Tel Serv. Co.,
Inc., 499 U.S. 340,
111 S. Ct. 1282 (1991). That case discarded the
"sweat-of-the-brow" doctrine for compilations in favor of an
analysis focusing on the originality of the compiler's expression.
"[C]opyright protects only the elements that owe their origin to
the compiler -- the selection, coordination, and arrangements of
facts." 499 U.S. at 359, 111 S.Ct. at 1295. "No matter how
original the format, however, the facts themselves do not become
original through association. . . . This inevitably means that the
23
copyright in a factual compilation is thin." 499 U.S. at 349, 111
S.Ct. at 1289. Focusing on Feist's test for originality, SSI
argues that many of the SACS input formats derive directly from
Synercom's STRAN program. Moreover, SSI posits, "data formats are
data formats": organizing parameters and variables as a series of
columns of engineering data amounts to a "garden variety
arrangement" required in any structural analysis program and is
similar to the unoriginal arrangement of names, addresses, and
telephone numbers in a telephone directory. SSI concludes that the
whole bundle of EDI's input formats and outputs reports is
uncopyrightable.
These arguments construe Feist both too broadly and too
narrowly. Whether Feist should apply at all to the formats in
question here is doubtful. As stated earlier, EDI's data cards do
not consist of mere "facts," nor do they portray a "compilation" so
much as a progressive demonstration of a particular engineering
program. But to the extent that Feist's definition of originality
applies here, it appears that EDI has selected data and arranged
their placement in a way that is unique and original to SACS. See
Lotus Dev. Corp. v. Borland Int'l Inc., 831 F. Supp. 223, 231 (D.
Mass. 1993) (Lotus V) (finding command menu interface copyrightable
by comparing it to compilation: "The selection, arrangement, and
manner of presentation in a compilation may provide the user with
a method or systematic manner of accessing the (uncopyrightable)
facts. Thus, copyright law protects only that part of a
compilation that the reader actually uses for selection of facts
24
that the reader wants to know"). The creativity inherent in EDI's
program is proved by the existence by other, dissimilar structural
engineering programs available in the market. The existence of
creativity is reinforced by SSI's observation that StruCAD
performs the same functions as SACS with significantly fewer input
formats.
4. User Formats as Dictated by Industry Standard
Based upon the nature of the offshore structural
engineering marketplace, SSI contends, EDI had to use the same or
similar formats to those it chose in order to provide a compatible,
standardized and efficient product for its customers. In other
words, scenes a faire dictated EDI's choice of input formats and
output reports in the same way that the external requirements of
the cotton market dictated the program in Plains Cotton, supra,
leading to a rejection of copyright protection in that case.12
Although the parties disagree over application of the doctrine in
this case, neither side cites any evidence to support its position.
On remand, the district court must consider whether or to what
12
A programmer's freedom of design choice may be circumscribed by
other extrinsic considerations such as the nature of the hardware on which the
program will run, compatibility requirements of other programs, computer
manufacturers' design standards, the demands of the industry being served, and
widely accepted programming practices within the computer industry. See
Altai, 982 F.2d at 709-10, citing 3 Nimmer § 13.03[F][3], at 13-65-71. In
Lotus I, for example, the court found that use of a rotated "L" screen display
for spreadsheets, the use of a slash key to invoke a menu system, "Q" for
quitting or exiting a system, and similar other common interfaces are not
copyrightable because their use is unoriginal, nonexpressive, or thoroughly
standardized. See Lotus
I, 740 F. Supp. at 78. This opinion deals only with
the externalities raised by SSI.
25
extent industry demand and practice in the offshore engineering
market dictated the SACS IV input and output formats.13
This finding is only the first step, however, for anyone
may copy uncopyrightable elements in a copyrighted work. SSI
argues that many of EDI's cards are unoriginal and thus
uncopyrightable. A close examination of the actual input formats
is required to determine whether the allegedly infringed cards are
copyrightable. Among the allegedly infringed cards, for instance,
some may be so generic, e.g., a "header" or an "end" card, that
they lack that minimal degree of creativity required for copyright
protection. If other cards for which EDI claims copyright
protection almost wholly derive from the input formats developed by
Synercom many years earlier, they would also lack the requisite
originality.14
Filtration has resulted in one area of potential
unprotectibility that must be considered on remand, and that
relates to the impact of the scenes a faire doctrine. SSI's other
13
Filtration may well render many of EDI's output formats
uncopyrightable. (An example of the parties' output reports is reproduced in
the appendix.) The remarkable similarities in some of these formats may be
due to the inherent qualities of the ideas expressed (merger) or compliance
with industry standards (scenes a faire). For example, each program must
identify individual structural members and the forces acting upon them in a
manner easily understood by engineers. The district judge will determine on
remand whether there are multiple ways to express these concepts consistent
with industry practice.
14
It appears that nine cards (TITLE, AMOD, SECT, GRUP, JOINT,
PERSET, LOADCN, LOAD, and LDCOMB) are virtually the same as those developed by
Synercom. A few have very slight modifications from Synercom's cards. For
example, the AMOD cards in SACS and StruCAD provide for three-digit load
condition numbers while STRAN allowed for only two-digit entries. This sort
of originality probably does not meet the minimal requirements demanded by
copyright. Similarly, the addition of columns for commentary is not
sufficient to imbue a recycled Synercom card with copyrightability.
26
global objections to copyright protection for the input formats and
output reports are ill-founded.
C. Comparison
After the district court completes the "filtration" of
the user interface as described, it must then decide whether SSI's
work is substantially similar to the copyrighted works. See n.4
supra. The district court never ruled on many of the factual
issues governing substantial similarity because of its view that
computer data formats are not copyrightable.
To determine substantial similarity, the court should
"focus on whether the defendant copied any aspect of this protected
expression." Altai, 982 F.2d at 710. In this case, it is probably
advisable for the court first to determine whether variations in
the registered and copyrightable format cards adopted by StruCAD
render the cards noninfringing elements of the larger work at the
individual card level. Then the court may determine whether the
subset of StruCAD cards that are individually substantially similar
to their counterparts in SACS, are, taken together, so
substantially similar to EDI's copyrighted work or a part thereof
as to constitute infringement. While a determination of
substantial similarity is, in the final analysis, a value judgment
that resists the imposition of a rigid analytical framework, this
only heightens the need for methodical analysis. The ultimate
focus, in accordance with EDI's contention, should be on the input
formats and output reports taken as a whole.
27
Another proposition to bear in mind is that the scope of
protection afforded by a copyright is not constant across all
literary works. Infringement is far more likely to have occurred
where a defendant has copied a memorable phrase from a short poem
than where the defendant has copied an explanatory phrase from a
voluminous textbook on biochemistry, because the law is more
protective of highly original and highly expressive works than it
is of functional and nonfiction works. This distinction is
recognized in Feist, where, because the allegedly infringed work
was a collection of facts, the Court noted that any copyright was
"thin." 499 U.S. at 349, 111 S.Ct. at 1289. The same cautious
approach to protection is appropriate for computer user interfaces.
To the extent that they are highly functional, or, like the output
formats in this case, to the extent that they contain highly
standardized technical information, they may lie very near the line
of uncopyrightability.15
This relatively narrow scope of copyright protection has
been adopted by several courts. In Lotus Dev. Corp. v. Borland
Int'l, Inc., 831 F. Supp. 202, 209 (D.Mass. 1993) (Lotus IV), Judge
Keeton referred to the scope of copyright protection as a sliding
15
As mentioned earlier, some cases may require courts to vary the
abstraction-filtration-comparison test to accommodate particular facts. We do
not find it necessary to do so, but by way of illustration, our interface
copyrightability analysis in this case has focused on three inquiries. First,
whether the interface is simply a blank form that fails to convey expression
to the user. Second, whether the interface is sufficiently user-directed and
interactive. Third, analogous to a compilation, whether the interface
provides original expression through the selection, sequence, and organization
of information provided to and collected from the user. In this case all of
these requisites were met. After applying other more standard
"copyrightability filters," such as scenes a faire, the district court will
determine whether the thin copyright EDI may enjoy has been infringed.
28
scale that changes with the availability of expressions for a given
idea, and he impliedly accorded computer interfaces only a narrow
protection. Noting that the menu commands and menu structure of
the computer spreadsheet program in that case were highly
functional, Judge Keeton emphasized that the defendant had
infringed by copying verbatim Lotus's entire command menu hierarchy
despite the availability of many different command structures to
perform the same functions. See also Apple Computer, Inc. v.
Microsoft Corp., 799 F. Supp. 1006, 1021 (N.D. Cal. 1992)
(determining scope of infringement for user interface: "[I]f
technical or conceptual constraints limit the available ways to
express an idea. . . copyright law will abhor only a virtually
identical copy of the original."); Atari Games Corp. v. Nintendo of
America, Inc.,
975 F.2d 832, 840 (Fed. Cir. 1992) (determining
infringement of nonliteral elements of computer program: "Even for
works warranting little copyright protection, verbatim copying is
infringement."); Digital Communications Assocs., Inc. v. Softklone
Distrib. Corp.,
659 F. Supp. 449 (N.D.Ga. 1987) (finding
infringement in a computer program's status screen which was
"virtually identical" with the plaintiff's); Harcourt Brace &
World, Inc. v. Graphic Controls Corp.,
329 F. Supp. 517, 525
(S.D.N.Y. 1971) (according narrow scope of protection to answer
sheet designed to be optically scanned by computers); 3 Nimmer,
§ 13.03[B][2][b] ("If the only original aspect of a work lies in
its literal expression, then only a very close similarity, verging
29
on the identical, will suffice to constitute an infringing copy.")
(citing cases).
III. INFRINGEMENT OF USER MANUALS
The district court found that the StruCAD manual
infringed EDI's copyright in its user manuals. This finding was
based entirely on text, pictures, diagrams, illustrated examples,
and flow charts depicted in the manuals, but not the input and
output formats. 785 F. Supp. at 583. After these findings were
entered, SSI revised its manual, but the parties could not agree as
to whether this new manual infringed. The district judge referred
the matter to a special master under Fed. R. Civ. Proc. 53. The
special master issued findings and conclusions of law in a report
in which it determined that SSI's new manual did not infringe. The
district judge adopted the special master's report the same day it
was filed.
EDI argues that the findings of the special master, to
the extent they were adopted by the district court, were clearly
erroneous. In addition to procedural objections, discussed below,
EDI insists that SSI's revised manual contains many examples of
allegedly infringing material from the old manual which the
district court had held to be infringing.
One example EDI emphasizes in particular is SSI's
repeated use of a table of default values of certain engineering
constants admittedly taken from EDI's copyrighted manuals. These
constants (specifically, drag and mass coefficients for structural
members) were allegedly researched and compiled by EDI as part of
30
its efforts to accurately represent these forces in its computer
program. They are not copyrightable, however, because they are
facts, despite the fact that EDI may have discovered them through
great expenditure of time or labor. See Feist, 499 U.S. at 347,
111 S.Ct. at 1288; Gates
Rubber, 9 F.3d at 842-43 (mathematical
constants used in computer program uncopyrightable).
If the district court decides on remand that StruCAD's
input formats infringe EDI's formats, the court must then reexamine
the StruCAD manual after SSI revises it to avoid infringement. The
district judge's rulings on other portions of SSI's manual seem
somewhat contradictory, for EDI offers considerable evidence that
SSI's revised manual incorporates many of the objectionable
features that the district court found infringing in its first
opinion. Nevertheless, it is unnecessary to review the revised SSI
manual until it has been reconsidered on remand.
IV. INFRINGEMENT RELATING TO HELP SCREENS
The parties did not thoroughly brief this issue on
appeal. It is evident, however, that SSI's help screens are not
substantially similar to EDI's copyrighted works. Although in many
cases StruCAD's help screens convey the same ideas and information
as EDI's user manuals, there is little verbatim copying of text.
Naturally, many of EDI's objections to StruCAD's help screens are
grounded in its objections to StruCAD's re-creation of its input
formats, to which the help screens usually refer. The final
infringement determination relating to the help screens must
31
therefore depend upon the court's evaluation of the input formats
on remand.
V. OBJECTIONS TO SPECIAL
MASTER'S REPORT AND PROCEDURES
Because of the remand, we need not discuss in detail
EDI's objections to the special master's report and procedure.
Should the district court decide to refer any questions on remand
to a special master under Rule 53, it must allow the parties ten
days to file objections to the master's report before rendering its
decision. This procedure was overlooked before. It is also
unclear whether the master strictly complied with the court's order
of reference and whether the master would have been well advised to
offer the parties a hearing, as Fed. Rule Civ. Proc. 53(d)
provides.
VI. LIABILITY OF GUNTUR
IN HIS INDIVIDUAL CAPACITY
EDI claims that the district court erred in dismissing
the claims against Rao Guntur in his individual capacity. Although
both Guntur and SSI were named as defendants, the district court
entered judgment against SSI alone and dismissed the personal
claims against Guntur because EDI had presented insufficient
justification for "pierc[ing] the corporate veil." 785 F. Supp. at
585. This holding was erroneous. EDI was not seeking recovery
against Guntur in his capacity as the principal owner of SSI, but
against Guntur as the individual who first infringed EDI's
copyright. Guntur was not acting at the direction of another but
initiated the copying for direct personal gain. As this court has
32
recognized in the context of trademark infringement, requiring a
piercing of the corporate veil to hold individuals liable would be
putting the cart before the horse. Mead Johnson & Co. v. Baby's
Formula Service, Inc., 402 F.2d 19, 23 (5th Cir. 1968) ("the fact
that the persons thus acting are acting for a corporation also, of
course, may make the corporation liable under the doctrine of
respondeat superior. It does not relieve the individuals of their
responsibility."). On remand, the district court must apportion
damages between Guntur and SSI.
VII. TRADE DRESS
AND UNFAIR COMPETITION CLAIMS
EDI argues that the district court erred in rejecting
EDI's claim that SSI violated section 43(a) of the Lanham Act, 15
U.S.C. § 1125(a), by infringing the trade dress of SACS. Trade
dress refers to the image and overall appearance of a product.
Allied Marketing Group, Inc. v. CDL Marketing, Inc., 878 F.2d 806,
812 (5th Cir. 1989). The Lanham Act prohibits passing off goods or
services as those of a competitor by employing substantially
similar trade dress which is likely to confuse consumers as to the
sources of the product. Blue Bell Bio-Medical v. Cin-Bad, Inc.,
864 F.2d 1253, 1256 (5th Cir. 1989). In this circuit, there are
two elements of a trade dress infringement claim. First, the trade
dress of a product may be protected as an unregistered trademark if
it is nonfunctional, distinctive, and has acquired a secondary
meaning. Second, a finding of infringement requires a
consideration of the likelihood of confusion. Taco Cabana
International, Inc. v. Two Pesos, Inc.,
932 F.2d 1113, 1117-18 (5th
33
Cir. 1991), aff'd, 112 S. Ct. 2753 (1992). This court will reverse
these relevant findings of fact only upon a showing of clear error.
Marathon Mfg. Co. v. Enerlite Products Corp.,
767 F.2d 214 (5th
Cir. 1985).
The district court's rejection of EDI's trade dress claim
was based on the second stage of the test through its finding that
there was no likelihood of confusion between the two programs.16
We find no clear error in the district court's holding that there
was little likelihood of confusion among the relevant users of the
computer programs at issue. Testimony at trial established that
both products were targeted at a fairly limited and sophisticated
market. Moreover, the printed pages of both parties' reports
clearly identify the vendor as EDI or SSI. No witness testified to
an instance of actual confusion between the products. Finally, the
Lanham Act is grounded in a belief that competitors should not pass
off their products as another's. Witnesses testified that SSI
explicitly differentiated its product from SACS in its marketing
efforts. Furthermore, these programs' trade dress is largely
irrelevant when sophisticated users decide which program to
purchase. We have no trouble affirming the district court's
finding that there was no likelihood of confusion.
16
It is an interesting question, unnecessary to reach here, whether
computer input formats and output reports involving highly technical factual
reports of engineering data are so inherently functional as not to be
protectible. Cf. Computer Care v. Service Systems Enterprises, Inc., 982 F.2d
1063 (7th Cir. 1992) (finding trade dress violation in copied format of highly
expressive computer form letters dealing with automobile repair business).
34
The same likelihood of confusion standard used for the
Lanham Act also applies to Louisiana's unfair competition statute.
Louisiana World Exposition, Inc. v. Logue, 221 U.S.P.Q., 589, 594
(E.D.La. 1983). We therefore find no error in the district court's
rejection of EDI's state law claim of unfair competition under La.
Rev. Stat. § 51:1405(A).
VIII. DAMAGES
The final issue is whether the district court erred in
awarding EDI $250,000 in damages for copyright infringement. With
the following observations, this issue will be revisited on remand.
EDI argues that the district court placed too much emphasis on the
fact that SSI was first to market, apparently by several months, a
program which was designed for a personal computer. EDI asserts
that the district court used this factor to reduce EDI's damages
from the $1.9 million it claimed it lost in profits over the years
1986 to 1990 to only $250,000. We agree that several months delay
in bringing a PC version of SACS to market was not sufficient
reason to reduce damages from nearly $2 million to $250,000. It is
not clear, however, that the district court relied on this factor
alone in reducing damages to the extent it did. The district court
also cited Fitzgerald Pub. Co. v. Baylor Pub. Co., 807 F.2d 1110,
1118 (2d Cir. 1986), which held that actual damages should reflect
the extent to which the market value of the copyrighted work at the
time of the infringement has been injured or destroyed by the
infringement. The court also indicated at one point that the
extent of copying might not justify fully compensating the
35
copyright owners. The district court may have determined that some
of the decline in EDI's profits was unrelated to SSI's entry to the
market or that SSI only engaged in minimal copying. This would be
a permissible finding; whether it was supported by the record we
need not decide.
CONCLUSION
The district court erred in concluding that EDI's input
formats and output reports, taken as a whole, may not qualify for
copyright protection. We must therefore REVERSE the district
court's holding that computer/user interfaces in the form of input
and output formats are uncopyrightable. We also REVERSE its
holding that Guntur is not personally liable. We REMAND to
determine whether the existence of industry standards precludes
copyright protection and whether there was infringement of the user
interfaces. On remand the district court must also reexamine
infringement of EDI's user manuals and help screens and apportion
damages between SSI and Guntur. We AFFIRM the court's other
rulings.
AFFIRMED in part, REVERSED in part and REMANDED.
