    “overlap to a significant degree, i.e., a person with a Ph.D. in a discipline related to biological sciences and having had at least two years of work experience. However, the parties’ proposals differ slightly in the specific subjects in which a POSA would have had a doctoral degree, and whether the person’s work experience must have been directly related to horseshoe crab Factor C. As an initial matter, we find that a rigid requirement as to the subject of a POSA’s doctoral degree (e.g., biochemical engineering, enzymology), or experience working specifically with horseshoe crab proteins, is not consistent with the evidence of record. See, e.g., Ex. 1067, 20:23–21:2 (Dr. Schaefer testifying that the fact the “name of [his] Ph.D. is immunology . . . does not change the fact that the core of [his] thesis training was really in molecular biology”), 22:3–15 (explaining “the fact that the production of proteins recombinantly is mostly species agnostic”); Ex. 1069, 45:20–47:17 (Dr. Morris testifying that whether a person is a POSA depends on the person’s “experience, [ ] publications,” and work done for the Ph.D. rather than the name of the Ph.D. program). We also find that evidence of record supports Petitioner’s assertion that, for purposes of defining a POSA, “[m]ore education could substitute for experience, and vice versa.” See, e.g., Pet. 19; Ex. 1065, 99:14–100:3. with respect to the claims of the ’318 patent would have had a Ph.D. in molecular biology, biochemistry, or a related discipline, and about two years of experience with cloning genes, expressing cloned genes as proteins, and/or characterizing such cloned genes and proteins, with more education being able to substitute for experience, and vice versa.

Limulus polyphemus.” Ex. 1006, 40. However, none of the remaining portions of ’767 application cited by Patent Owner relate directly to L. polyphemus; instead, the remaining portions of ’767 application cited by Patent Owner are directed to other species, in particular the Japanese horseshoe crab T. tridentatus. Further, Patent Owner’s witness, Dr. Schaefer, conceded that the ’767 application does not contain Factor C sequence information for L. polyphemus. See, e.g., Ex. 1067, 44:25–45:23.

In this regard, we note that adequate written description of a biological molecule, such as a HEK293 recombinant L. polyphemus Factor C protein, requires “more than a mere statement that it is part of the invention and reference to a potential method for isolating it”; instead, what is required is “‘a precise definition, such as by structure, formula, chemical name, or physical properties,’ not a mere wish or plan for obtaining the claimed chemical invention.” The Regents of the” slip op. at 21

    “Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1364 (Fed. Cir. 2007). Neither do we see Petitioner’s arguments regarding the December 10, 2013 priority date to be “mutually opposed” as Dr. Schaefer testified. Ex. 1067, 216:4– 24. Instead, we credit evidence of record, including Dr. Jain’s testimony and the February 22, 2018 Mizumura Declaration, that existence of the full sequence would permit a more complete analysis and that such an analysis would provide a POSA with a reasonable expectation that the claimed L. polyphemus recombinant protein would have a residual activity within the claimed range. See, e.g., Ex. 1029, 2–5; Ex. 1010, 48; Ex. 1065, 117:14– 130:24 (explaining that comparison of partial sequences in the Tokunaga 1991 publication showed “difference around the cleavage site” between T. tridentatus and L. polyphemus but comparison of the full sequence revealed that “the catalytic triad of histidine, serine, aspartate . . . to be more similar between Tachypleus and Limulus”). Patent Owner asserts that “Petitioner’s reliance on a statement made by Dr. Mizumura in a declaration submitted during prosecution of the ’767 Application fails to fill the gap in the analysis” regarding reasonable expectation of success, because the declaration “offers no evidence of the percentage of conserved amino acid substitutions that exist to support the conclusion that a POSA would have expected residual activity to be maintained between Tachypleus tridentatus and Limulus polyphemus” PO Resp. 47. However, as noted above, Dr. Mizumura provides an alignment of Factor C proteins from the two different species of horseshoe crab, determines that the similarity between the amino acid sequence is 99.5%, states that the amino acid residues that can undergo N-type sugar chain that L. polyphemus, like T. tridentatus, would also be less susceptible to inhibition by ions. Ex. 1029, 4–5. For the reasons discussed above, we also disagree with Patent Owner’s assertion that Petitioner’s reasonable expectation of success argument is “nothing more than conclusory assertions with no support.” PO Resp. 46. Rather, we find Petitioner has shown, by a preponderance of the evidence, that a POSA would have had reason to combine the teachings of Mizumura and the ’498 PCT, with a reasonable expectation of success in arriving at the Factor C protein recited in claim 21.” slip op. at 38

We determine that this language satisfies at least two of the criteria set forth in Alnylam. Specifically, the sentence at “refers to” to explain what qualifies as major peaks.

    “Petitioner has the better position. Huang2 teaches crosslinking and provides a reason for doing so (stability). In particular, Huang2 states: “To better mimic skin ECM, electrospun collagen fibers have been fabricated, however, the rapid degradation and poor mechanical properties determine that either crosslinking or combination with other materials is necessary to obtain a stable scaffold.” Ex. 1005, 1791 (emphasis added). It is true that, in describing work actually carried out, Huang2 states that blending with PCL was performed and does not mention crosslinking. See id. at 1792 (“Nanofibrous matrices of PCL and Collagen at a weight ratio of 3:1 were fabricated using electrospinning as previously described.”). However, the prior art – here, Huang2 – is not limited to that which it describes having created. See In re Mills, 470 F.2d 649, 651 (C.C.P.A. 1972) (“a reference is not limited to the disclosure of specific working examples”); see also In re Lemelson, 397 F.2d 1006, 1009 (CCPA 1968) (“The use of patents as references is not limited to what the patentees describe as their own inventions or to the problems with which they are concerned. They are part of the literature of the art, relevant for all they contain.”); In re Fritch, 972 F.2d 1260, 1264 (Fed. Cir. 1992) (“It is well settled that a prior art reference is relevant for all that it teaches to those of ordinary skill in the art.”). Huang2 teaches two stabilization methods when using collagen in scaffolds. Huang2 states that one or the other “is necessary to obtain a stable scaffold” (when using collagen), but it does not preclude or teach away from using Patent Owner-cited testimony of Dr. Mikos is not as definitive as Patent Owner suggests; Dr. Mikos’s testimony is that a person of ordinary skill in the art “typically would not have done both.” Ex. 2015 ¶64 (emphasis added). The bottom line is that Huang2 teaches the person of ordinary skill in the art two ways to stabilize scaffolds/matrices comprised of collagen, provides a reason for doing so (stability), and does not teach away from using both. We are persuaded that a “scaffold comprising crosslinked fibers comprising collagen” would have been obvious in view of the cited teachings of Huang2.” slip op. at 33

    “We are not persuaded by Appellant’s citations to either reference. As discussed above, Petitioner’s Ground 1 is premised on a person of ordinary skill in the art altering the native flat sheet structure of Huang2 by rolling it into a jelly-roll structure as taught by Kuo. See Pet. 41 (Beginning its claim 2 arguments with the following: “Claim 1 is obvious for the reasons expressed above in § X.A., supra, which are incorporated herein.”); see also Pet. Reply 17 (“[B]ased on the explicit teaching of Kuo, a POSA would have been motivated to take the electrospun flat scaffold made by the techniques of Huang2, seed it with the desired cells, and roll it to treat a tendon and ligament.” (emphasis added)). Indeed, the paragraphs of Kuo that Petitioner cites for disclosing “scaffold sheets,” explicitly describe rolling them into jelly-roll like structures. See Ex. 1018 ¶7 (stating that “the sheet is spirally contacting a scaffold sheet of fibrous material with a cell; and rolling the scaffold sheet in a jelly-roll like manner to form a spirally wound tissue construct”), ¶22 (describing a method comprising “forming a tissue construct by contacting a scaffold sheet of fibrous material with a cell; and rolling the scaffold sheet in a jelly-roll like manner to form a spirally wound tissue construct” and implanting it in a patient). Petitioner fails to argue that that “one or more elongated sheets” recited in claim 2 would encompass the rolled structure of its proposed modification. Nor does Petitioner articulate a claim construction argument that could support such an argument. Petitioner has failed to prove, by a preponderance of the evidence, that claim 2 would have been obvious over Huang2 and Kuo.” slip op. at 42

Covad Communications Group, Inc., 262 F.3d 1258, 1268 (Fed. Cir. 2001). Among the criteria to consider in whether the patentee acted as a lexicographer to define a claim term include (a) whether the patent specification included the statement in question under a section for marks, (c) whether the sentence uses the term “refer to,” which generally “conveys an intent for [that sentence] to be definitional,” and (d) whether there are other non-limiting terms (e.g., “for example,” or “include”) that contradict a definitional intent. Alnylam Pharms., Inc. v. Moderna, Inc., 138 F.4th 1326, 1333 (Fed. Cir. 2025) (alteration in original). At the outset, we agree with Patent Owner that the Specification purports to define “major peaks” in the following sentence: “The ‘major peaks’ herein refer to peaks higher than the average of the peaks in the result.” Ex. 1001, 13:6–7. We determine that this language satisfies at least two of the criteria set forth in Alnylam. Specifically, the sentence at issue sets out “major peaks” in quotation marks, and then uses the term “refers to” to explain what qualifies as major peaks. That is not the end of the inquiry, however, as we find there is still some ambiguity as to whether the patentee intended to define “major peaks” so as to require so-called “minor peaks” in the claimed invention.

    “As discussed above, we agree with Patent Owner that the sentence it cites from the Specification of the ’223 patent bears sufficient hallmarks of lexicography. However, the Specification nonetheless lacks any indication that so-called “minor peaks” are a necessary component of the claimed invention. “Although it is firmly settled that an applicant may act as a 9 Figure 8B does not contain “major peaks” despite clearly depicting two “peaks higher than the average of the [three or possibly four] peaks in the result” because none of the peaks is a reflection of fiber alignment. 10 After presenting claim construction arguments based on Ayres 2008, Patent Owner confusingly states: “Finally, whether Ayres-2008 supports [Patent Owner’s] construction is irrelevant.” PO Sur-Reply 5 (emphasis added). definition that is contrary to the ordinary meaning of a claim term unless it communicates a deliberate and clear preference for this alternative definition.” Kumar v. Ovonic Battery Co., 351 F.3d 1364, 1368 (Fed. Cir. 2003). There is no indication that the patentee sought to require “minor peaks” within the scope of the claimed invention. Nor are we persuaded that a person of ordinary skill in the art would readily understand the scope of the term “major peaks” to require non-major peaks. We interpret the Specification’s statement that “‘major peaks’ herein refer to peaks higher than the average of the peaks in the result” (Ex. 1001, 13:6–7) to be teaching a person of ordinary skill in the art how to identify or discern “major peaks,” which indicate a principal axis of alignment, from any non-major peaks, which would be caused by something else. We conclude that a person of ordinary skill in the art would consider “major peaks” as used in the ’223 patent as referring to peaks that reflect the sole axis or primary axis of fiber alignment. See, e.g., id. at code (54) (“ALIGNED FIBER AND METHOD OF USE THEREOF”), code (57) (“A scaffold comprising an aligned fiber.”), 1:6–7 (“The invention relates to an aligned fiber and method of use thereof.”), 1:11–12 (“The invention relates to a scaffold comprising an aligned fiber.”), 13:16–17 (“Alignment of the fibers in the scaffold may be measured by a fast Fourier transform (FFT) analysis.”). This would certainly include peaks materially higher than the average of the peaks in the result, but it would not be limited to situations involving peaks of different heights or require so-called minor peaks. Based on the totality of the evidence before us, we do not construe the claims to require non-major peaks.” slip op. at 16

    “Petitioner argues that, for the aligned sample, a major peak occurs at about 90° as identified by Petitioner’s annotation (red arrow). Pet. 30–31. As support, Petitioner directs us to Huang2’s explicit description of what the peak indicates, namely that “[t]he narrow peak of the normalized intensity values in anisotropic [aligned] matrices (Figure 1C) indicated that PCL/Coll nanofibers aligned along a single axis (Fig. 1B).” Id. at 31 (alterations in original) (quoting Ex. 1005, 1794). Patent Owner disputes that the illustrated peak is a major peak solely based on the lack of any lesser peaks. See PO Resp. 13 (“[T]he height of the sole peak is identical to—not higher than—the average height of the peaks in the result.”). As discussed above, however, we do not construe “major peaks” as requiring the existence of non-major peaks. We find that the illustrated peak in the Aniso plot of the FFT analysis results (Figure 1C) is a major peak within the meaning of the claim. The evidence in support of this finding is overwhelming. First, the term “Aniso” as used in Huang2 refers to fibers “with alignment.” Ex. 1005, 1792. Huang2 describes fabricating such matrices of aligned fibers with electrospinning, the same method used to impart alignment in the ’223 patent. Id. at 1791–92. Huang2 visually confirms that the fibers in fact are aligned via scanning electron microscopy. Id. at Fig. 1B. Further, Huang2 explicitly states that the peak illustrated in the Aniso plot of the FFT analysis results (Figure 1C) is caused by the fact that the “PCL/Coll nanofibers aligned along a single axis (Fig. 1B).” Id. at 1794. This is precisely what electrospinning may yield aligned fibers and images of aligned fibers will yield FFT results with major peaks. Ex. 1001, 2:18–19, 4:46–60, 13:16–26. Additionally, Huang2 itself considers the peak illustrated in the Aniso plot of the FFT analysis to be significant, stating: “In contrast [to the Aniso plot], the lack of a significant peak for the fibers collected on a stationary surface [(i.e., without electrospinning)] demonstrated no preferred fiber orientation in the isotropic matrices” (i.e., the Iso plot). Ex. 1005, 1794. Indeed, the asserted major peak in the Aniso plot shown in Huang2’s Figure 1C is higher than any other data point on the plot. For these reasons, we find the peak to be a major peak.15 Petitioner acknowledges that Figure 1C only reports its results” slip op. at 32

    “Clearly, the second Hall-Ellis declaration is offered to prove that McCloskey is a prior art printed publication. See, e.g., Ex. 1085 ¶50 (“In view of the foregoing, it is my opinion that [McCloskey] was publicly available no later than [January 3, 2008].”). Thus, the second Hall-Ellis declaration should have been served within ten business days of Patent Owner’s February 15, 2024, objection to the admissibility of McCloskey. See 37 C.F.R. § 42.64(b)(2) (“The party relying on evidence to which an objection is timely served may respond to the objection by serving supplemental evidence within ten business days of service of the objection.”). In its Opposition to the Motion to Exclude, Petitioner argues that, under Hulu LLC v.

The Board in Hulu does state that, “if the patent owner challenges a reference’s status as a printed publication, a petitioner may submit a supporting declaration with its reply to further support its argument that a reference qualifies as a printed publication.” Hulu at 15 (37 C.F.R. § 42.23). However, the Board’s statement was referring to the scope of permissible reply arguments under 37 C.F.R. § 42.23(b).

The Board in Hulu does not purport to interpret 37 C.F.R. § 42.64 or even discuss supplemental evidence. Petitioner clearly missed the deadline imposed by 37 C.F.R. § 42.64(b)(2), which was triggered by Patent Owner’s February 15, 2024, objection to McCloskey. Patent Owner’s Motion to Exclude is granted with respect to the second Hall-Ellis declaration (i.e., Ex. 1085). Despite the exclusion of the second Hall-Ellis declaration, there is ample evidence in the record demonstrating that McCloskey is a prior art printed publication. McCloskey itself states: “Received: 31 January 2007 / Accepted: 29 May 2007 / Published online: 23 October 2007.” Ex. 1004, 1. McCloskey additionally states that it was published in a 2007 print issue of “Biochem Genet,” with Petitioner adding that the full name of the journal is BIOCHEMICAL GENETICS and that McCloskey was published in a December 2007 volume of the journal. Id.; Pet. 29. McCloskey also includes a copyright notice by “Springer Science+Business Media, LLC” with a date of date of 2007. Ex. 1004, 1. Patent Owner argues that this is unreliable hearsay that should be excluded. PO Mot. To Exclude 4 (citing Neste Oil Oyj v.

    “Clearly, the second Hall-Ellis declaration is offered to prove that McCloskey is a prior art printed publication. See, e.g., Ex. 1065 ¶50 (“In view of the foregoing, it is my opinion that [McCloskey] was publicly available no later than [January 3, 2008].”). Thus, the second Hall-Ellis declaration should have been served within ten business days of Patent Owner’s October, 27, 2023, objection to the admissibility of McCloskey. See 37 C.F.R. § 42.64(b)(2) (“The party relying on evidence to which an objection is timely served may respond to the objection by serving supplemental evidence within ten business days of service of the objection.”). Because it was not filed until March 29, 2024, Patent Owner’s Motion to Exclude is granted with respect to the second Hall-Ellis declaration. In its Opposition to the Motion to Exclude, Petitioner argues that, under Hulu LLC v. Sound View Innovations, LLC, No. IPR2018-01039, Paper 29 (Dec. 20, 2019) (precedential), it was allowed to wait until its Reply to file the second Hall-Ellis declaration. Paper 37, 1–2. The Board in Hulu does state that, “if the patent owner challenges a reference’s status as a printed publication, a petitioner may submit a supporting declaration with its reply to further support its argument that a reference qualifies as a printed publication.” Hulu, at 15 (37 C.F.R. § 42.23). However, the Board’s statement was referring to the scope of permissible reply arguments under 37 C.F.R. § 42.23(b). See Hulu at 14 (quoting 37 C.F.R. § 42.23(b)’s requirement that “[a] reply may only respond to arguments raised in the corresponding opposition, patent owner preliminary response, or patent owner response”). The Board in Hulu does not purport to interpret 37 C.F.R. § 42.64 or even discuss supplemental evidence. Petitioner clearly missed the deadline imposed by 37 C.F.R. § 42.64(b)(2), which was triggered by Patent Owner’s October 27, 2023, objection to McCloskey.

We are persuaded by Petitioner’s reasoning, including specifically the quoted material in the preceding string citation to the Petition, for modifying Schotz’s system to include Rovira’s signal as well as various components for processing such a signal. See Kahn, 441 F.3d at 988. We note that “[a] person of ordinary skill is also a person of ordinary creativity, not an automaton,” and, in modifying Schotz’s system to include Rovira’s signal, would have made any necessary additional modifications such that Schotz’s system could process appropriately Rovira’s signal.

    “essentially of” for “being composed of.” PO Resp. 11 (citing AFG Indus., Inc. v. Cardinal IG Co., 239 F.3d 1239, 1245 (Fed. Cir. 2001)). In AFG, the Court noted that, “[i]n 1942, the Court of Customs and Patent Appeals [had] stated that ‘“composed of” should be regarded as synonymous with “consisting of.”’” AFG, 239 F.3d at 1245 (quoting In re Bertsch, 132 F.2d 1014, 1019 (CCPA 1942)). However, as further explained in AFG, the Court of Customs and Patent Appeals had “qualified this statement . . . by remarking that ‘the words “composed of” may under certain circumstances be given, in patent law, a broader meaning than “consisting of.”’” Id. (quoting In re Bertsch, 132 F.2d at 1020). The Court in AFG ultimately construed “composed of” to mean “consisting essentially of.” Id. (“[W]e do agree based on the specification and other evidence before us that the term ‘composed of’ in this case is not completely closed. Rather, we think that ‘composed of’ in this case should be interpreted in the same manner as ‘consisting essentially of.’”).

For purposes of this Decision, we construe “being composed of” to mean “consisting essentially of,” as Patent Owner argues.5 In conclusion, we construe “first film being composed of crystalline metal containing nitrogen therein,” as recited in independent claims 1 and 5, to mean “first film consisting essentially of crystalline metal containing nitrogen therein.”6” slip op. at 11

    “As to Petitioner’s predictable-results assertion, Petitioner persuasively argues that a person of ordinary skill in the art would have added nitrogen to the crystalline tantalum layer of Ding for three independent reasons. First, Petitioner argues that the presence of nitrogen in Ding’s crystalline tantalum layer would make it more easily removable by chemical mechanical polishing (“CMP”), which removal by polishing both Zhang and Ding teach to do. Pet. 24–26 (citing Ex. 1003 ¶¶140, 142, 143; Ex. 1004, 1:30–34, 4:34–37; Ex. 1005, 7:56–65; Ex. 1019, 12–13; Ex. 1021, 354–63). Second, Petitioner argues that the presence of nitrogen in Ding’s crystalline tantalum layer would inhibit, to some additional extent, copper diffusion. Id. at 26–29 (citing Ex. 1003 ¶¶144–146; Ex. 1023, 8). Third, Petitioner argues that adding a small amount of nitrogen to Ding’s crystalline tantalum layer would reduce its resistivity, which was known to help reduce a device’s power consumption and RC delays. Id. at 29–30 (citing Ex. 1003 ¶147; Ex. 1015, 81 (Table 1)). Patent Owner counters that none of these purportedly predictable results are realistic. PO Resp. 46–52. With respect to the first reason offered by Petitioner (to make the first film more susceptible to CMP), Patent Owner argues that: (A) adding only “[a] small amount of nitrogen” to Ding’s crystalline tantalum layer would not change its CMP characteristics; and (B) “[a]dding significant amounts of nitrogen” would result in Ding’s previously crystalline layer becoming amorphous. Id. at 48. Patent Owner does not disclose what it considers “small” and “significant” amounts of nitrogen. Id. As a result, we cannot apply Patent Owner’s argument (even if it were persuasive) to the facts before us. Also, Patent Owner’s argument is based exclusively on declaration testimony that does not cite to any underlying evidence, let alone documentary evidence. See id. at 47–49 (citing Ex. 2011 ¶¶190–98). In contrast, Petitioner’s argument is supported by declaration testimony, which, in turn, is based on underlying evidence, including documentary evidence. See Pet. 24–26 (citing Ex. 1003 ¶¶140, 142, 143; Ex. 1004, 1:30–34, 4:34– 37; Ex. 1005, 7:56–65; Ex. 1019, 12–13; Ex. 1021, 354–63); see also Ex. 1003 ¶139. With respect to the second reason offered by Petitioner (to inhibit, to some additional extent, copper diffusion), Patent Owner argues that, in Petitioner’s asserted combination, “there would be no nitrogen to provide any copper diffusion benefit.” PO Resp. 49. Patent Owner’s argument is premised on Zhang teaching exclusively an upper surface of pure tantalum. Id. But, Zhang explicitly teaches that the upper surface may have a nitrogen content of, for example, 1%, 2%, 3%, or 4%. See Ex. 1004, 3:59–62 (“At the upper surface, the atomic percent tantalum may be at least 95% and the atomic percent nitrogen may be less than 5% if copper adhesion is particularly problematic.”). With respect to the third reason offered by Petitioner (to reduce resistivity), Patent Owner argues that adding nitrogen would actually increase resistivity. As pointed out by Petitioner, however, Patent Owner’s declarant, Harlan R. Harris, Ph.D., conceded that adding nitrogen does lower resistivity. Reply 17–18 (quoting Ex. 1036, 125:3–20). Dr. Harris testified as follows: Q. When the nitrogen flow ratio is zero in the ’324 patent, and the power is kept constant, wouldn’t that result in a film that could be pure tantalum? A. All three of those data points are at the exact same position on the graph. The N2 concentration, which is the numerator of the ratio, is set at zero. And in this particular position, the nitrogen concentration would be assumed to be zero in the film. Q. So is it within the scope of what’s taught in the ’324 patent to have a film that would have no nitrogen at all? A. It’s also apparent to anyone who is examining this of skill in the art that you can decrease from that number, which is favorable in terms of the value of resistivity by adding flow rate in the data points for all of the positions greater than zero. So you decrease resistivity by the addition of any amount of nitrogen, therefore, a person skilled in the art would not be motivated to not have nitrogen, based on this data. Q. You’re referring to the decrease in resistivity as nitrogen is added? A. Yes. Q. Which is desirable? A. You want the resistivity to go down. Ex. 1036, 124:15–125:20. We are satisfied by each of Petitioner’s proffered reasons for why a person of ordinary skill in the art would have added nitrogen to Ding’s crystalline tantalum layer, as taught by Zhang. Petitioner has shown, by a preponderance of the evidence, that claims 1 and 5 would have been obvious over Ding and Zhang.” slip op. at 24

Patent Owner’s Motion to substitute claims 11 and 12 is premised, incorrectly, on Zhang requiring pure tantalum (and, thus, no nitrogen) at the upper surface of its tantalum-rich tantalum nitride film. In fact, Zhang does not require any portion of the tantalum-rich tantalum nitride film to be pure tantalum. Ex. 1004, 3:53–54 (“The tantalum-rich tantalum nitride film has a range of approximately 0-30 atomic percent nitrogen.”). And, Zhang explicitly teaches that the upper surface may include nitrogen. Id. at 3:57– 62 (“A lower atomic percent nitrogen at the upper surface typically gives better adhesion to copper films. At the upper surface, the atomic percent tantalum may be at least 95% and the atomic percent nitrogen may be less than 5% if copper adhesion is particularly problematic.”); Ex. 1036, 40:1–6, 42:2–9, 42:15–21, 54:14–20 (Dr. Harris acknowledging that the upper surface of the film would contain some nitrogen). Accordingly, a preponderance of the evidence establishes that Patent Owner’s proposed claims 11 and 12 are not patentable over the art of record in this inter partes review. Put another way, and as Petitioner argues, claims 11 and 12 (like challenged claim 5) are unpatentable as they claim subject matter that would have been obvious over Ding in view of Zhang. See 35 U.S.C. § 103(a); Amend Opp. 6–7 (“The instituted obviousness ground[] based on Zhang and Ding already include[s] the newly-added limitations Patent Owner seeks to add in its Substitute Claims 11–13. Thus, the Substitute Claims 11–13 remain unpatentable over each of the instituted grounds.”).14 Patent Owner’s Motion to Amend is denied with respect to claims 11 and 12.” slip op. at 33

    “construction in the Decision on Institution. The evidence indicates that the term “Peripheral Component Interconnect (PCI) bus transaction” refers to a particular industry standard, not just any communication with an interconnected peripheral component. Industry literature and dictionaries use the proper noun “Peripheral Component Interconnect” and the abbreviation “PCI” to refer to a particular industry specification for a local bus. See, e.g., Ex. 2001, 1; Ex. 2002, 6–7; Ex. 2003, 7–8. The challenged claims recite “Peripheral Component Interconnect” as a proper noun and abbreviate it as “PCI,” indicating that the challenged claims use those terms consistent with the understood industry meaning. Ex. 1001, col. 43, ll. 48–49, col. 44, l. 6; see Azure Networks, LLC v. CSR PLC, 771 F.3d 1336, 1348 (Fed. Cir. 2014). The written description similarly uses the abbreviation “PCI” to refer to a particular industry standard, and uses the common noun “peripheral bus” to refer to a generic peripheral bus. Compare Ex. 1001, col. 5, ll. 31–33 (“The present invention . . . interface[s] two PCI or PCI-like buses”), with id. at col. 10, ll. 53–55 (“Additionally, the peripheral controller is coupled to a clock control logic, a configuration signal, and a peripheral bus.”) (emphasis added).” slip op. at 6

    “obvious over Horst and LVDS Owner’s Manual; claims 56 and 59 would have been obvious over Horst, LVDS Owner’s Manual, and Pocrass; and claim 58 would have been obvious over Horst, LVDS Owner’s Manual, and Deters. Pet. 58–59. A claim is unpatentable as obvious under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which the subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) any objective indicia of non-obviousness. Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966).

    “Owner argues that paragraphs 10–24 and 31–37 of Exhibit 1031 should be excluded as irrelevant and prejudicial because Petitioner relies on those paragraphs to support improper arguments in the Reply. PO Mot. 8. Petitioner argues in the Reply that the TNet transaction in Horst includes PCI address bits, and that claim 54 only requires communicating two bits of a PCI bus transaction. PO Mot. 1. Patent Owner contends that both arguments exceed the scope of a proper reply, as set forth in 37 C.F.R. § 42.23(b), and that the portions of Exhibit 1031 that Petitioner relies upon to support those arguments should be excluded as irrelevant and prejudicial. PO Mot. 2–4, 6, 7. Patent Owner’s argument is not persuasive. Patent Owner argues in the Response that the TNet transaction in Horst does not include PCI address bits. PO Resp. 27–29. As such, Petitioner’s argument in the Reply that the TNet transaction includes PCI address bits is responsive to an argument raised in the Response. See 37 C.F.R. § 42.23(b) (generally permitting a reply to respond to arguments raised in a response). Patent Owner also argues in the Response that claim 54 requires communicating a 32-bit PCI address. PO Resp. 8–11. As such, Petitioner’s argument in the Reply that claim 54 only requires communicating two bits of a PCI bus transaction is responsive to an argument raised in the Response. Because we are not persuaded that the identified arguments in the Reply are improper, the premise of Patent Owner’s Motion to Exclude Exhibit 1031 fails. Therefore, Patent Owner’s Motion to Exclude paragraphs 10–24 and 31–37 of Exhibit 1031 is denied.” slip op. at 16

    “The term “enclosure unit” encompasses lavatories, aircraft closets, and aircraft galleys. Given the grounds of unpatentability that Petitioner raises, there is no need to further construe this term. 2. “lavatory stall unit” Whereas independent claim 1 recites “enclosure unit,” independent claim 9 recites “lavatory stall unit.” Patent Owner proposes the latter be construed as “a single room, enclosed on all sides, having a toilet and washbasin and large enough to fit a person inside.” PO Resp. 12. For reasons similar to those with respect to “enclosure unit,” we reject Patent Owner’s proposed construction of “lavatory stall unit.” Further, given the grounds of unpatentability that Petitioner raises, there is no need to provide an express construction for this term. More specifically, Petitioner does not rely on any particular prior art lavatory. Indeed, Petitioner does not rely on either of the asserted references to teach a “lavatory stall unit,” instead relying on the knowledge and skill of a person of ordinary skill in the art.” slip op. at 9

    “These proposed constructions would render the claim language “in a vertical plane” meaningless because tilting a seatback between an upright position and another position would have no effect on the shape of the aft surface of the seatback. Therefore, we do not adopt them. See Cardiac Pacemakers, Inc. v. St. Jude Med., Inc., 296 F.3d 1106, 1115 (Fed. Cir. 2002) (proposed construction that rendered a portion of the claim language meaningless held improper). Rather, we construe “in a vertical plane” according to its ordinary and customary meaning and consistent with the specification, which contrasts a forward wall in a vertical plane (see Fig. 1—the prior art) against a recessed forward wall (see Fig. 2—an embodiment of the claimed invention). In sum, the full limitation at issue encompasses an aft portion (in the case of claim 1) and an aft portion with an exterior aft surface (in the case of claims 9, 21, and 31) that has a flat shape but which is not within a vertical plane. This is within the broadest reasonable construction in light of the Specification, which discloses a substantially conforming recessed forward wall positioned behind the seat (see Ex. 1001, Fig. 2), as opposed to a wall that is flat in a vertical plane (see id. at Fig. 1). 4. “forward wall portion is shaped to substantially conform to the shape of the” slip op. at 10

    “motivated to efficiently use space on an aircraft, as evidenced by Betts, “to provide more room for passengers.” Id. ¶ 65 (quoting Ex. 1003, 1:6–7). Mr. Anderson further testifies that Betts teaches the person of ordinary skill in the art a recessed forward wall configuration that uses space more efficiently than a flat configuration, and that a person of ordinary skill in the art would have been motivated to apply the recessed configuration to other aircraft enclosures, including lavatories. Patent Owner argues that a person of ordinary skill in the art “would have been discouraged from attempting to tailor Betts’ divided space design to any lavatory stall unit (or any other enclosure unit) because Betts required separate enclosures divided both functionally and spatially.” PO Resp. 29. But, Petitioner’s ground of unpatentability is not premised on whether it would have been practical or possible to convert Bett’s “divided space” (i.e., its overhead coat compartment and floor luggage space) into a lavatory. Rather, Petitioner argues that it would have been obvious to apply Bett’s recessed forward wall design to other aircraft enclosures, including a lavatory.
