LUCY H. KOH, District Judge.
In this patent case, a jury found that Samsung had infringed several of Apple's patents, including Claim 50 of U.S. Patent No. 7,864,163 ("the '163 Patent") and four design patents: No. D618,677 ("the D'677 Patent"); No. D593,087 ("the D'087 Patent"); No. D604,305 ("the D'305 Patent"); and No. D504,889 ("the D'889 Patent"). Samsung now argues that Claim 50 of the '163 Patent and all four design patents are invalid for failure to meet the definiteness requirement of 35 U.S.C. § 112. See Motion on Samsung's Non-Jury Claims, ECF No. 1988 ("Mot.").
As an initial matter, this claim is not waived. Apple asserts that this argument is waived because Samsung did not seek claim construction of the term "substantially centered" or include the indefiniteness issue in its pretrial statement. However, failure to seek construction of a term during claim construction does not constitute waiver of an indefiniteness argument. For one thing, under this District's Patent Local Rules, the parties were limited in the number of terms for which they could seek construction.
Samsung contends that the term "substantially centered" in the '163 Patent is an indefinite term of degree, which cannot be construed because no objective anchor is provided in the specification. Claim 50, the only claim at issue in this litigation, reads:
U.S. Patent No. 7,864,163 B2 (emphasis added).
The imprecise claim term at issue here, "substantially," is a word of degree. See, e.g., LNP Engineering Plastics, Inc. v. Miller Waste Mills, Inc., 275 F.3d 1347, 1359 (Fed.Cir.2001) (considering the term "substantially completely wetted"); Exxon, 265 F.3d at 1377 (considering the phrase "to increase substantially"). "When a word of degree is used the district court must determine whether the patent's specification provides some standard for measuring that degree." Seattle Box Co. v. Indus. Crating & Packing, Inc., 731 F.2d 818, 826 (Fed.Cir.1984). If the specification does not provide a standard for imposing a more precise construction of the term, the Federal Circuit has ruled that imposing a more precise construction would be error. See Playtex Products, Inc. v. Procter & Gamble Co., 400 F.3d 901, 907 (Fed.Cir.2005); Cordis Corp. v. Medtronic AVE, Inc., 339 F.3d 1352, 1360 (Fed.Cir.2003).
For example, in Playtex, the Federal Circuit, quoting Liquid Dynamics Corp. v. Vaughan Co., Inc., 355 F.3d 1361, 1368 (Fed.Cir.2004), stated that "substantial" implies "approximate" rather than "perfect." 400 F.3d at 907. The Playtex Court further stated that, "the definition of `substantially flattened surfaces' adopted by the district court introduces a numerical tolerance to the flatness of the gripping area surfaces of the claimed applicator. That reading contradicts the recent precedent
Similarly, in Anchor Wall Systems, Inc. v. Rockwood Retaining Walls, Inc., 340 F.3d 1298, 1311 (Fed.Cir.2003), the Federal Circuit held that the phrase "generally parallel" envisions "some amount of deviation from exactly parallel." The Anchor Wall Court also noted that "words of approximation, such as `generally' and `substantially,' are descriptive terms `commonly used in patent claims "to avoid a strict numerical boundary to the specified parameter."'" Id. at 1310-11 (internal citations omitted). Furthermore, the Court noted that "nothing in the prosecution history of the #015 patent family clearly limits the scope of `generally parallel' such that the adverb `generally' does not broaden the meaning of parallel." Id. at 1311.
In Liquid Dynamics Corp., 355 F.3d at 1369, the Federal Circuit construed a claim with the phrases a "substantial helical flow" and a "substantially volume filling flow" as "all flow patterns that are generally, though not necessarily perfectly, spiral, and that fill much, though not necessarily all, of the tank's volume." The Court held that, "Because the plain language of the claim was clear and uncontradicted by anything in the written description of the figures, the district court should not have relied upon the written description, the figures, or the prosecution history to add limitations to the claim." Id. at 1368.
Other Federal Circuit cases have also held that the term "substantially" does not require a strict numerical boundary. "We note that like the term `about,' the term `substantially' is a descriptive term commonly used in patent claims to `avoid a strict numerical boundary to the specified parameter.'" Ecolab, Inc. v. Envirochem, Inc., 264 F.3d 1358, 1367 (Fed. Cir.2001) (quoting Pall Corp. v. Micron Separations, Inc., 66 F.3d 1211 (Fed.Cir. 1995)). "Expressions such as `substantially' are used in patent documents when warranted by the nature of the invention, in order to accommodate the minor variations that may be appropriate to secure the invention." Verve, LLC v. Crane Cams, Inc., 311 F.3d 1116, 1120 (Fed.Cir. 2002). Thus, the law is clear that a court need not, and indeed may not, construe terms of degree to give them greater precision, absent a standard for imposing a more precise construction in the specification.
In the instant case, the Court finds no standard for measuring the precise boundaries of "substantially centered" in the specification. Accordingly, under Federal Circuit precedent, it would be inappropriate for this Court to issue a construction of "substantially centered" that gives it greater precision.
The Federal Circuit has never suggested, however, that this lack of precision constitutes a lack of construability, so as to render a term of degree indefinite. Indeed, the Federal Circuit has construed such terms of degree. In so doing, the
Samsung has not attempted to argue that a court would be unable to issue such a plain meaning-based construction of the term "substantially centered."
The parties have also presented extrinsic evidence that the term "substantially centered" can be understood by persons of ordinary skill in the art. The Federal Circuit has explained that although courts "have emphasized the importance of intrinsic evidence in claim construction, we have also authorized district courts to rely on extrinsic evidence, such as expert testimony." Datamize, 417 F.3d at 1348 (internal quotation marks and citation omitted). The opinion of an expert can illuminate the meaning of an ambiguous term of degree. See Datamize, 417 F.3d at 1353-54; Amgen, Inc. v. Chugai Pharm. Co., Ltd., 927 F.2d 1200, 1218 (Fed.Cir.1991). The testimony of an inventor can also shed light on the meaning of a term insofar as the inventor is a person of ordinary skill in the art, but testimony about the inventor's subjective state of mind cannot bear on definiteness. See CBT Flint Partners, LLC v. Return Path, Inc., 654 F.3d 1353, 1360 (Fed.Cir.2011) (considering an inventor's testimony as testimony of one of skill in the art); Bancorp Services, L.L.C. v. Hartford Life Ins. Co., 359 F.3d 1367, 1370 (Fed.Cir.2004) (noting a district court's proper rejection of inventor testimony concerning subjective intent).
Regarding "substantially centered," Apple's expert, Dr. Karan Singh, testified that "a person of ordinary skill in the art, or actually even a — a person, a layman, would tell you that visually it's by and large centered." Declaration of John Pierce in support of Samsung's Reply
Similarly, Samsung's expert, Mr. Gray, testified during his deposition that he had determined that some of Samsung's accused products were capable of substantial centering as contemplated in the '163 Patent:
Declaration of Nathan Sabri in support of Apple's Opposition ("Sabri Decl."), Exh. 3, Gray 5/4/12 Depo. Tr. 181:24-182:14. Mr. Gray further testified that a second box in some of the Samsung accused products was "substantially centered" on the touch screen display:
Sabri Decl., Exh. 3, Gray 5/4/12 Depo. Tr. 185:16-22. However, at trial, Mr. Gray testified that "I don't know when something is substantially center [sic]. I know when something is fully centered or not centered, but `substantially centered' is ambiguous. How would a patent — how would an engineer understand how to make something substantially centered or not?" Gray 8/15/12 Trial Tr. 2922:19-25.
The Court recognizes that "[t]he test for indefiniteness does not depend on a potential infringer's ability to ascertain the nature of its own accused product to determine infringement, but instead on whether the claim delineates to a skilled artisan the bounds of the invention." Star Scientific, Inc. v. R.J. Reynolds Tobacco Co., 537 F.3d 1357, 1373 (Fed.Cir.2008) (quoting Invitrogen Corp. v. Biocrest Mfg., L.P., 424 F.3d 1374, 1384 (Fed.Cir.2005) (quoting SmithKline Beecham Corp. v. Apotex Corp., 403 F.3d 1331, 1341 (Fed.Cir. 2005))). Nonetheless, Mr. Gray's ability during his deposition to determine whether parts of the accused Samsung products were substantially centered or not supports the conclusion that "substantially centered" is not insolubly ambiguous.
In sum, the Federal Circuit's cases establish that precise construction is not required, or even permissible, when a patent uses a term of degree such as "substantially," and the specification does not provide a standard for measuring the precise boundaries of that term of degree. Moreover, the evidence suggests that persons of ordinary skill in the art can understand the meaning of the term "substantially centered." Accordingly, the Court finds that the term "substantially centered" is not indefinite.
Apple claims that Samsung's design patent indefiniteness defense, like the utility patent indefiniteness defense, is waived. Apple asserts that Samsung cannot argue design patent indefiniteness now, because Samsung submitted an interrogatory response to a question about invalidity defenses that did not provide any details about the defense. Opp'n at 3. Apple further explains that Judge Grewal then struck expert testimony that included material beyond what was disclosed in that interrogatory response. ECF No. 1144.
This failure to disclose relevant evidence does not constitute waiver of the claim. Indeed, Samsung has continued to raise this issue, from its answer, ECF No. 80 at ¶ 278, through summary judgment briefing, ECF No. 931-1 at 15, and at trial, in its proposed jury instructions, ECF No. 1694 at 123-24. Thus, Apple has been on notice of this defense throughout the litigation. Accordingly, the Court properly entertains Samsung's motion at this time.
Samsung argues that all four of the design patents at issue in this case — the D'889, D'305, D'677, and D'087 Patents — are indefinite, for a variety of reasons.
The standard for indefiniteness is explained above. The definiteness requirement applies to design patents as well as utility patents. See Litton Systems, Inc. v. Whirlpool Corp., 728 F.2d 1423, 1440-41 (Fed.Cir.1984) (overruled on other grounds by Egyptian Goddess, Inc. v. Swisa, Inc., 543 F.3d 665 (Fed.Cir.2008)). Thus, even in design patents, "[c]laims are considered indefinite when they are not amenable to construction or are insolubly ambiguous ... Indefiniteness requires a determination whether those skilled in the art would understand what is claimed." Young v. Lumenis, Inc., 492 F.3d 1336, 1346 (Fed.Cir.2007).
There is little clear precedent on the question of how this standard is to be applied to design patents. Courts considering the question have analyzed whether "a person of skill in the art" would get "an overall understanding of the total substance of the designs." Antonious v. Spalding & Evenflo Companies, Inc., 217 F.3d 849 (Fed.Cir.1999) (unpublished); see also Seed Lighting Design Co., Ltd. v. Home Depot, C 04-2291, 2005 WL 1868152 (N.D.Cal., Aug. 3, 2005) (considering whether a person skilled in the art would understand the bounds of a design patent claim from inconsistent drawings); HR U.S. LLC v. Mizco Int'l, Inc., CV-07-2394, 2009 WL 890550 (E.D.N.Y., Mar. 31, 2009) (design patent would be indefinite where "the overall appearance of the design is unclear").
As indefiniteness is intimately linked to claim construction, the cases discussing claim construction in design patents bear on the indefiniteness analysis. Further, the test for infringement certainly bears on the test for indefiniteness, since the ultimate inquiry for indefiniteness is whether a person having ordinary skill in the art could tell what is claimed — and therefore, what infringes. See LNP Engineering, 275 F.3d at 1360. Design patents protect "overall designs" rather than individual specific features. Int'l Seaway Trading Corp. v. Walgreens Corp., 589 F.3d 1233, 1239-41 (Fed.Cir.2009); see also Egyptian Goddess, 543 F.3d at 665 (noting the risk that a verbal description will lead a jury to "plac[e] undue emphasis on particular features of the design and... focus on each individual described feature in the verbal description rather than on the design as a whole"). Design patents are infringed when "an ordinary observer, familiar with the prior art designs,
To prevail on its indefiniteness defense, Samsung must show by clear and convincing evidence that a designer of ordinary skill in the art would not understand what is claimed. See Datamize, 417 F.3d at 1348. This is a high standard, necessary to give effect to the statutory presumption of validity afforded to issued patents. See 35 U.S.C. § 282.
Samsung has made a range of arguments about why the various design patents are indefinite. Specifically, Samsung argues that the D'889 Patent is indefinite for four reasons: (1) drawings showing the design oriented in different directions make it impossible to know which way the design is supposed to be oriented or where features actually appear; (2) the use of broken lines is inconsistent, making it difficult to tell which elements are claimed and which are not; (3) the use of surface shading is different in different pictures, making it unclear what type of surface is being represented; and (4) the 035 Mockup
Several of Samsung's arguments concern use of drafting techniques (broken lines and shading). In support of its argument that inconsistent use of broken lines is per se indefinite, Samsung cites In re Blum, 54 C.C.P.A. 1231, 374 F.2d 904 (1967). The court in Blum noted that "[d]otted and broken lines may mean different things in different circumstances" and that "in each case it must be made entirely clear what they do mean" to avoid indefiniteness. Id. at 907. This case, however, precedes Young, Datamize, Exxon, and other cases explaining that a claim need only be amenable to construction to be definite, and precedes Egyptian Goddess, which explains the responsibilities of
Indeed, the Court's claim construction of the design patents shows that these features are amenable to construction. ECF No. 1425 (construing the use of broken lines, oblique lines, and shading in all four of the design patents). Similarly, the Federal Circuit found no difficulty in interpreting the claimed designs in the D'677, D'087, and D'889 Patents. See Apple, Inc. v. Samsung Electronics Co., Ltd., 678 F.3d 1314 (Fed.Cir.2012) (preliminary injunction opinion). Given that this Court and the Federal Circuit have construed the claims in these patents, they are not "insolubly ambiguous" or "not amenable to construction." Young, 492 F.3d at 1346.
Moreover, the Federal Circuit has explicitly recognized that it is appropriate for district courts to issue interpretations of drafting conventions, see Egyptian Goddess, 543 F.3d at 680. If the use of drafting conventions had to be facially obvious for the patent to be valid, no such interpretations would ever be necessary. Further, the law is clear that the fact that claim construction is necessary does not render the patent indefinite. See, e.g., Exxon, 265 F.3d at 1375 (patent is not indefinite even if claim construction is quite difficult). Accordingly, the patents are not per se indefinite due to their inconsistent use of drafting techniques including shading and broken lines.
Regarding the differently oriented drawings in the D'889 Patent, the Court sees nothing inconsistent about these drawings. They show a device facing different directions, but there is no place in which an identifiable feature of the design appears in two different places in two different figures, taking into account the rotation of the object depicted. The fact that a feature may be invisible in one of the figures due to the resolution and orientation of the drawing does not make it impossible to determine whether or not the feature is part of the design. Samsung argues that the "environmental features" in Figures 1-4 are "switched to different sides" in Figures 5-8. Mot. at 6. Without any further specifics in Samsung's argument, the Court cannot be certain as to what features Samsung intends to refer, but having examined the drawings, the Court sees no inconsistency. There is a circular hole on one edge and a rectangular opening on another edge visible in Figure 2; the same features are visible in the same relative places in Figures 6 and 8, though the entire object is rotated. Further, contrary to Samsung's assertion, there is simply no requirement that a claimed design must have a particular preferred orientation; indeed, Samsung cites no law even suggesting that there is. The fact that the D'889 Patent shows a design in different orientations merely shows that the particular orientation — landscape or portrait, head-on or perspective — is not part of what is claimed.
Samsung also argues that the fact that the iPad 2 and the 035 Mockup both embody the D'889 Patent necessarily renders the patent indefinite. But the law is clear that the same design patent can have multiple embodiments. See Antonious, 217 F.3d at 7; In re Rubinfield, 47 C.C.P.A. 701, 270 F.2d 391, 391 (1959). Thus, the fact that both of these objects are said to embody the design does not necessarily propose a definiteness problem. Samsung seems to suggest that if
Next, Samsung claims that because only one of the figures in the D'305 Patent is in color, there is no possible way to know whether color is part of the claimed design. As Samsung acknowledges, the Model of Patent Examining Procedure explains that color drawings are allowed where "color is an integral part of the claimed design." MPEP 1503.02(V). Thus, by including a color drawing, Apple has made clear that color is necessary to the design. The regulations governing color drawings make clear that they are to be used only rarely and only where necessary to convey what is claimed. See 37 C.F.R. § 1.84(a)(2). Nowhere do the regulations say that if one drawing is in color, all drawings must be in color, and Samsung cites no authority for that proposition. Given the presumption of validity afforded to issued patents, see Datamize, 417 F.3d at 1347, the Court declines to adopt a rule requiring all depictions of the design to be in color in order for color to be part of the claimed design.
Samsung next argues that the D'677 and D'087 Patents are indefinite because it is unclear whether the lozenge and rectangle shapes are below, in, or on top of the surface. But it does not matter "whether the lozenge and rectangle features on the front faces are below a surface, material breaks on the surface, or features drawn on top of a continuous surface," Mot. at 8, as long as any of those could produce interchangeable visual effects that would appear "substantially the same to the ordinary observer." Egyptian Goddess, 543 F.3d at 678. As this Court explained in its Claim Construction Order, a design patent protects an overall visual impression, and "it will be for the jury to decide whether the accused device's `lozenge-shaped element would appear as it does in the figures.'" ECF No. 1425 at 7. In other words, the design patent need not specify how the lozenge shape is created. It need only provide the visual standard for comparison. It may be possible to produce the same overall visual impression with the lozenge in any one of those three positions, relative to the smooth surface. This fact does not render the design patent indefinite; it simply means that there may be more than one way to manufacture an article that embodies the claimed design.
Finally, Samsung argues that Apple's "named inventors and other witnesses" testified "that they could not understand the designs reflected in Apple's patents." Reply at 3 n. 1 (citing exhibits to Pierce Reply Decl.). Generally, the witnesses to whom Samsung points express a lack of familiarity with the conventions used in the drawings, or a lack of understanding about what design patents are. However, the witnesses' reluctance to verbally interpret the drawings presented in depositions as parts of patents subject to intense litigation does not, in and of itself, establish indefiniteness. Rather, the testimony Samsung cites consistently indicates a lack of familiarity with design patent conventions. See, e.g., Pierce Reply Decl. Exh. 10 ("Q: And why is it you can't
Further, Apple presents some trial testimony of witnesses who were able to interpret the drawings. Most notably, Samsung's design expert, Itay Sherman, testified that the designs were obvious and functional (see, e.g., Tr. 2578:10-21; 2579:8-20; 2581:22-25). As Apple points out, it would be difficult to have an opinion that a given design was obvious without understanding what the design actually was.
Taken together, Samsung's arguments, which all concern the quality and specificity of the drawings, are in contrast to the types of defects that courts have found constituted design patent indefiniteness. For example, in Seed Lighting, the lamp was depicted with a base that had one shape in one drawing and a completely different shape in another drawing. 2005 WL 1868152 at *9. The difference could not be attributed to the way in which the design was represented; there were unambiguously two different shapes in the two different pictures. The Federal Circuit in Antonious confirms that where the ambiguities concern representation, and not the actual article, a court need not find indefiniteness. 217 F.3d at 7-8 (no indefiniteness where discrepancies between drawings may be due to differing use of perspective). The distinction between drafting inconsistencies and actual ambiguity is especially relevant here, where the Court has been able to construe the drafting techniques, as the Federal Circuit has stated that district courts may do. See Egyptian Goddess, 543 F.3d at 680. In sum, all of Samsung's alleged sources of indefiniteness concern how the design is represented, rather than the nature of the design itself. These ambiguities are not fatal to patents that this Court must view with a strong presumption of validity. Accordingly, Samsung has not established indefiniteness by clear and convincing evidence, and Apple's design patents remain valid.
For the reasons stated above, the Court finds that neither the '163 Patent nor Apple's design patents are invalid for indefiniteness.
