LOKEN, Chief Judge.

       This is a copyright dispute between two organizations that offer competing
courses to prepare students to pass the Project Management Professional (PMP) Exam
given by the Project Management Institute (PMI). Rita Mulcahy filed the lawsuit,
claiming copyright infringement and unfair competition by Cheetah Learning LLC
and by Jeff Schurrer, an instructor who distributed allegedly infringing materials to
Cheetah students. The district court granted Mulcahy partial summary judgment and
a permanent injunction on her claim that defendants infringed her copyrighted work,
PMP Exam Prep. Cheetah and Schurrer appeal. We conclude there are genuine
issues of material fact regarding whether PMP Exam Prep infringes PMI’s exclusive
right to prepare derivative works based on its preexisting copyrighted work and
whether PMP Exam Prep is a fair use of that work. Accordingly, we reverse the grant
of partial summary judgment and vacate the permanent injunction.

                                  I. Background.

       Established in 1969, PMI is a not-for-profit association for project management
professionals (PMPs) that now “supports over 100,000 members in 125 countries
worldwide.” As part of its continuing and seemingly successful effort to establish
project management as a true profession, PMI first offered a PMP certification exam
in 1984 and first published a work entitled Project Management Body of Knowledge
in 1987. In 1996, PMI published a superseding copyrighted work entitled Guide to
the Project Management Body of Knowledge, which we will refer to as the PMBOK.
PMI advertises that the PMBOK is approved by the American National Standards
Institute and is “[t]he foundation document for project management training and/or
education.” PMI’s PMP exam has been “based upon” the PMBOK during the period
relevant to this dispute. However, the PMBOK’s introductory statement of purpose
suggests that it serves as a desk reference work for practicing project managers as
well as a “consistent structure” for PMI’s certification of PMPs. There is no
testimony by a PMI representative in the summary judgment record, nor does the
record reveal whether PMI has copyrighted PMP exam materials.

      PMI certification has come to be viewed as an important credential, creating
a market for textbooks and courses that prepare aspiring PMPs to pass the PMI exam.
PMI website materials in the record suggest that PMI, colleges and universities, and
numerous private vendors have entered this market. Because PMI bases the PMP
exam on the PMBOK, a comprehensive reference work, it is hard to imagine that a
vendor could devise a successful course teaching students to pass the PMP exam
without using -- or plagiarizing -- the PMBOK. In this regard, PMI’s copyright
notice in the front of the PMBOK advises:

                                         -2-
      All rights reserved. Permission to republish in full is granted freely. No
      part of this work may be reproduced or transmitted in any form . . .
      without prior written permission of the publisher.

Likewise, a PMI website warns:

      Anyone wishing to use excerpts from the PMBOK Guide must obtain
      written permission to do so and pay the appropriate permission fee,
      where applicable. This includes PMI members, PMI Components and
      PMI Registered Education Providers.

       Mulcahy is an expert in the field of project management who offers test
preparation courses and materials to teach students to pass the PMP exam. To this
end, Mulcahy wrote and copyrighted PMP Exam Prep. The book begins with
materials specifically focused on passing the PMP exam that have no counterparts in
the PMBOK, such as sections entitled “An Overview of the Exam,” “Types of
Questions on the Exam,” “How to Study for the Exam,” and “Tricks for Taking the
Exam.” However, the subsequent sections, which are entitled “The Materials” and
take up 150 of the work’s 165 pages, track the PMBOK’s organization of the project
management “knowledge areas” and reproduce or condense the materials presented
in the PMBOK. Although PMP Exam Prep states that it is “intended to work hand-in-
hand” with the PMBOK, and the record includes a PMI website that says,“Get Rita’s
book,” whether PMI authorized Mulcahy to use excerpts from the PMBOK in her
work is a disputed issue of fact.

       Cheetah offers a variety of exam preparation and professional training courses.
Founder Michelle LaBrosse testified that she uses “a unique educational model which
utilizes dietary control, yoga meditative techniques, color recognition, state
conditioning and psych-acoustics to accelerate the learning process.” In 2000,
Cheetah retained Eric Nielsen to develop the substantive content for a PMP exam
preparation course. Cheetah began offering the four-day course in September 2001,

                                         -3-
using the PMBOK as the “primary reference” and also distributing to students loose-
leaf materials called the Candidate Notetaker. LaBrosse was soon advised of
significant similarities between Cheetah’s Candidate Notetaker and Mulcahy’s PMP
Exam Prep. LaBrosse compared the two works and informed Mulcahy’s attorney that
she “had revised Cheetah’s course materials to remove what I believed to be the
allegedly infringing content.” Unsatisfied, Mulcahy filed this lawsuit. Nielsen
testified that he used PMP Exam Prep and other reference works in preparing the
Cheetah course materials and sample test questions.

       Ruling on the parties’ cross motions for summary judgment, the district court
granted Mulcahy summary judgment on her copyright infringement claim, concluding
that (i) Mulcahy’s copyright is valid because PMP Exam Prep does not infringe
PMI’s copyright in the PMBOK, (ii) alternatively, PMP Exam Prep is a fair use of the
PMBOK, and (iii) Cheetah’s course materials are substantially similar to PMP Exam
Prep and therefore infringe Mulcahy’s copyright as a matter of law. The court
broadly enjoined defendants from “using, copying, selling, distributing, or
displaying” specific Cheetah materials created between August 2001 and September
2002 and all other materials “substantially similar to any edition” of PMP Exam
Prep.1 Though copyright damage issues remain unresolved, we have jurisdiction to
review the court’s grant of a permanent injunction. 28 U.S.C. § 1292(a)(1). If
summary judgment was improvidently granted on Mulcahy’s claim of copyright
infringement, the permanent injunction must be vacated. See Randolph v. Rodgers,

, 856 (8th Cir. 1999).



      1
        By permanently enjoining defendants from using “any materials that are
substantially similar to any edition of Plaintiff’s PMP Exam Prep,” paragraph 3.b. of
the court’s order threatens defendants with contempt sanctions if they continue using
revised Cheetah course materials that were not before the court, contrary to the
principle that blanket injunctions to obey the law are disfavored. See Jake’s, Ltd.,
Inc. v. City of Coates, 

, 904 (8th Cir. 2004).

                                   II. Discussion.

       Two elements are required to establish copyright infringement, ownership of
a valid copyright and copying of original elements of the work. Feist Publ’ns, Inc.
v. Rural Tel. Serv. Co., 

, 361 (1991). Here, we need only consider the
first element because we agree with defendants that the district court erred in
concluding as a matter of law that PMP Exam Prep is not an unauthorized derivative
of the PMBOK and that any copying of the PMBOK in PMP Exam Prep was a “fair
use” within the meaning of 17 U.S.C. § 107.2

      A. Unauthorized Derivative. The statutory rights of a copyright owner include
the exclusive right “to prepare derivative works based upon the copyrighted work.”
17 U.S.C. § 106(2). The Copyright Act broadly defines a derivative work as -

      a work based upon one or more preexisting works, such as a translation,
      musical arrangement, dramatization, fictionalization, motion picture
      version, sound recording, art reproduction, abridgment, condensation,
      or any other form in which a work may be recast, transformed, or
      adapted.

17 U.S.C. § 101. One who violates the copyright owner’s right to create derivative
works is an infringer. See 17 U.S.C. § 501(a).

      A derivative work may itself be copyrighted if it has the requisite originality.
However, “the copyright is limited to the features that the derivative work adds to the
original.” Pickett v. Prince, 

, 405 (7th Cir. 2000); see Stewart v. Abend,

, 223 (1990). Moreover, because the owner of the original copyright has
the exclusive right to prepare derivative works, the creator of an original derivative


      2
       We do not consider defendants’ further contention that Mulcahy’s copyrights
are unenforceable because she filed knowingly false copyright applications.
                                         -5-
work is only entitled to a copyright if she had permission to use the underlying
copyrighted work. See 17 U.S.C. § 103(a); Dam Things from Denmark v. Russ
Berrie & Co. Inc., 

, 563 (3d Cir. 2002); Gracen v. Bradford Exch., 

, 302 (7th Cir. 1983). Thus, if the PMP Exam Prep is an unauthorized
derivative work of the PMBOK, Mulcahy’s copyrights are invalid.

       The district court did not discuss the concept of a derivative work. It simply
concluded that PMP Exam Prep does not infringe PMI’s copyright in the PMBOK
because, while the two works have “many substantive details in common,” they are
not substantially similar “in substance, purpose, presentation, and functionality.” The
court applied the two-part test for determining substantial similarity adopted by this
court in diverse copyright infringement cases such as Hartman v. Hallmark Cards,
Inc., 

, 120 (8th Cir. 1987), Schoolhouse, Inc. v. Anderson, 

,
729 (8th Cir. 2002), and Taylor Corp. v. Four Seasons Greetings, LLC, 

, 1043 (8th Cir. 2003).

       While substantial similarity is the test we use in determining copyright
infringement, here the issue is whether Mulcahy’s book is a derivative work. In
general, the two tests are similar. In the words of a leading copyright treatise, “Unless
sufficient of the pre-existing work is contained in the later work so as to constitute
the latter an infringement of the former, the latter by definition is not a derivative
work.” 2 Nimmer on Copyright § 8.09[A], p. 8-138 (2004); see Litchfield v.
Spielberg, 

, 1357 (9th Cir. 1984) (“a work is not derivative unless it has
been substantially copied from the prior work”), cert. denied, 

(1985).
But as this case illustrates, a determination of what is substantial or sufficient must
take into account the nature of the derivative work inquiry.

      PMI has created and copyrighted a multi-purpose reference work, the PMBOK,
and has made that work the “foundation” of its test that a student must pass to receive
PMI’s valuable PMP certification. Without doubt, an outside educator could obtain

                                          -6-
copies of the PMBOK from PMI and lecture students on how to use that work to pass
the exam without infringing the PMBOK copyright. In addition, the educator could
create and distribute written materials on subjects not covered in the PMBOK -- such
as “How to Study for the Exam” and “Tricks for Taking the Exam” -- without
infringing. But Mulcahy has done far more. Large portions of her PMP Exam Prep
appear to copy, condense, and adapt those portions of the PMBOK that are relevant
to passing the exam. She admits that these portions of her work are derived from and
based upon the PMBOK. The question is whether this copying, condensing, and
adapting of the PMBOK encroaches upon, i.e., infringes, PMI’s exclusive right “to
prepare derivative works based upon the copyrighted work.” 17 U.S.C. § 106(2).
This issue cannot be answered by looking at the percentage of the PMBOK that has
been condensed or copied in PMP Exam Prep. Rather, a reasonable factfinder could
find that PMP Exam Prep is an infringing derivative work if it copied or condensed
the qualitative core of one marketable portion of the multi-purpose PMBOK. See
Castle Rock Ent., Inc. v. Carol Pub. Group, Inc., 

, 138-39 (2d Cir. 1998).
It is true that, in most infringement cases, “[i]nfringement of expression occurs only
when the total concept and feel of the works in question are substantially similar,”

. But the derivative work issue, like the fair use issue,
should turn on “the qualitative nature of the taking.” Harper & Row Publishers, Inc.
v. Nation Enters., 

, 565 (1985). Thus, a work may be found to be
derivative even if it has “a different total concept and feel from the original work.”
Castle 

.

        Mulcahy argues that the PMBOK is entitled to only limited protection because
it is “a common project management lexicon,” a collection of underlying facts and
theories that cannot themselves be copyrighted. The Supreme Court has warned that
“the copyright in a factual compilation is thin” because “a subsequent compiler
remains free to use the facts . . . to aid in preparing a competing work.” 

. That principle may apply here. But PMI’s website materials in the
summary judgment record suggest that the PMBOK may be an original work intended

                                         -7-
to transform project management into a recognized profession, rather than a mere
compilation of well-known facts and ideas. In that case, the work’s organization and
presentation would reflect far more protectible originality than, for example, the
copyrighted “tables of information on area public and private schools” at issue in

. Again, this is a fact-intensive issue not properly
decided as a matter of law on a summary judgment record.3

     For these reasons, we conclude that the district court erred in deciding that
Mulcahy’s PMP Exam Prep is not a derivative work as a matter of law.

       B. Fair Use Doctrine. Alternatively, Mulcahy argues and the district court
concluded that PMP Exam Prep is a fair use of the PMBOK as a matter of law. The
statute, 17 U.S.C. § 107, sets forth four non-exclusive factors that “shall” be
considered in determining whether an otherwise infringing use is a non-infringing fair
use. Though all four must be considered together, the fourth factor -- “the effect of
the use upon the potential market for or value of the copyrighted work” -- “is
undoubtedly the single most important element of fair use.” Harper & 

. The district court concluded that Mulcahy’s use was fair because the
introduction to PMP Exam Prep tells students, “You need both the PMBOK and this
book to prepare for the exam,” and thus “the effect of Mulcahy’s work would likely
improve the potential market for and enhance the value of the PMBOK.”




      3
        Mulcahy also argues that, if PMP Exam Prep is a derivative work, PMI ratified
her use of the PMBOK by not responding when she sent PMI a pre-publication of the
first PMP Exam Prep and by selling PMP Exam Prep in PMI’s online bookstore. See
Eden Toys, Inc. v. Florelee Undergarment Co., Inc., 

, 34 n.6 (2d Cir.
1982). This, too, is an issue requiring a trial that explores the extent of PMI’s right
to prepare derivative works and, if the right extends to PMP exam teaching materials
based on the PMBOK, the manner in which PMI has exploited that right.
                                         -8-
       In our view, the effect of Mulcahy’s use is not so clear. In the first place,
students may find that PMP Exam Prep is such an effective condensation and
adaptation that they need not obtain and study the PMBOK. But more importantly,
PMI has created a for-profit education market by offering a valued certification exam.
PMI offers courses on passing its exam, demonstrating an intent to exploit that
market. By basing its exam on the copyrighted PMBOK, PMI has also created a
market for selling or licensing this work to educators and students; “the potential for
destruction of this market by widespread circumvention of the plaintiffs’ permission
fee system is enough, under the Harper & Row test, ‘to negate fair use.’” Princeton
Univ. Press v. Mich. Document Servs., Inc., 

, 1388 (6th Cir. 1996) (en
banc), cert. denied, 

(1997). Moreover, by publishing a comprehensive
condensation of the portions of the PMBOK relevant to passing the exam, Mulcahy
may have deprived PMI of “the capacity arbitrarily to refuse to license one who seeks
to exploit the work.” 

. Fair use is a mixed question of law
and fact. Here, the issue of fair use, like the issue of derivative work, raises genuine
issues of material fact.

       In addition, a finding that Mulcahy’s copyrights are valid only because PMP
Exam Prep is a fair use of the PMBOK would likely affect other issues. Mulcahy
emphasizes the extent to which Cheetah’s materials copy PMP Exam Prep. But “[a]n
author’s right to protection of the derivative work only extends to the [original]
elements that [she] has added to the work; [she] cannot receive protection for the
underlying work.” Dam 

; see 

(“copyright protects only those constituent elements of a work that possess more than
a de minimis quantum of creativity”). Thus, the factfinder “must filter out and
disregard” the copying of non-protected elements -- such as elements of PMP Exam
Prep that are a fair use of the PMBOK -- in determining whether defendants are guilty
of copyright infringement. Cavalier v. Random House, Inc., 

, 822-23
(9th Cir. 2002).

                                   III. Conclusion.

       For the foregoing reasons, Paragraph 1.a. of the district court’s order dated July
28, 2003, is reversed, the permanent injunction in paragraph 3. is vacated, and the
case is remanded for further proceedings not inconsistent with this opinion.
