    “We find that a rigid requirement as to the subject of a POSITA’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 that “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 POSITA 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 POSITA, “[m]ore education could substitute for experience, and vice versa.” See, e.g., Pet. 22; Ex. 1065, 99:14–100:3. Accordingly, based on the entirety of the trial record, we find a POSITA with respect to the claims of the ’109 patent would have had a 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. A POSITA may also have collaborated with others, including those with specific experience in utilizing or assessing horseshoe crab Factor C for endotoxin detection and quantitation.” slip op. at 9

    “Neither party proposes an express construction of any claim term. See Pet. 22–23 (not proposing any constructions); PO Resp. 23 (“Patent Owner agrees that the terms can be afforded their plain and ordinary meaning.”). However, Patent Owner states that some of Petitioner’s arguments implicitly construe claim 1 in an erroneous manner. PO Resp. 23–28. “For example, Petitioner argues that ‘an adequate written description would have to either disclose representative examples of the possible working cascades of various proteins or some accurate structural feature of the claimed proteins that allow them to function in the claimed assay as a whole.’” Id. at 23 (quoting Pet. 35). Patent Owner argues that, contrary to what Petitioner’s argument allegedly implies, “Claim 1 is directed to a method for producing an endotoxin assay agent” and does not require the use – Owner that claim 1 does not require the use of endotoxin assay agent. However, the claimed endotoxin assay agent must be capable of performing the assay, as counsel for Patent Owner acknowledged. Tr. 83:5–9.” slip op. at 10

  • BurdenNot shown unpatentable

    “In this case, to show that the claims of the ’109 patent are unpatentable for lack of written description, Petitioner would have needed to show that the specification as filed (i.e., the ’420 application) fails to reasonably convey to those skilled in the art that Patent Owner had possession of the claimed subject matter as of the July 3, 2023, filing date. Petitioner did not. Pet. 23–24. Nor does Petitioner’s declarant offer testimony that could support such a showing. See Ex. 1003 ¶50 (“I have been asked to provide my opinions as to the state of the art in this field for purposes of determining what the inventors disclosed as their invention as of December 10, 2013.”), ¶51 (“Whenever I offer an opinion in this declaration about the knowledge of a POSA, the manner in which a POSA would have understood the claims of the ’109 patent or its description, the manner in have been led to do based on the prior art, I am referencing the December 10, 2013 timeframe.”). In our Institution Decision, we stated: Although the ’420 application is essentially identical to the ’767 application, the person of ordinary skill in 2013 is not the same as in 2023. See Ariad, 598 F.3d at 1351 (“[T]he [written description] test requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” (emphasis added)). Thus, the information presented in the Petition, which is limited to the perspective of a 2013 POSITA, does not demonstrate that it is more likely than not that at least 1 of the claims challenged in the Petition is unpatentable for lack of written description. Inst. Dec. 12 (alterations in original). During trial, Petitioner did not present any further arguments in support of Ground 1. See generally Pet. Reply. Petitioner has failed to prove that claims 1–9 are unpatentable for failing to meet the written description requirement set forth in 35 U.S.C. § 112(a).” slip op. at 12

    “Although the evidence before us shows that, in 2013, a POSITA knew how to recombinantly express genes in expression systems such as CHO or HEK-293 cell lines, the evidence shows that this was true only for genes whose genetic sequences were known or readily available. See, e.g., Ex. 1069, 34:11–22 (“Q. Okay. So you would agree that the creation of the recombinant protein requires the underlying sequence of, as you said, the original animal? A. Of course.”) Because it is undisputed that, in 2013, the genetic sequence for Limulus polyphemus Factor C was unknown, or least not publicly available, Falko-Gunter does not support a finding of adequate written description here.

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.

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. Although “[n]o length requirement exists for a disclosure to adequately describe an invention,” Falko-Gunter, 448 F.3d at 1365–1366, we are persuaded that a POSA would not, based on the totality of the above disclosures, reasonably understand that the inventors were in possession of the claimed HEK-293 recombinant L. polyphemus Factor C protein, in view of the state of the art as of December 10, 2013. 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

Here, the challenge claims recite two types of functional limitations. First, independent claim 10 requires the coformer to have a second chemical functionality, which is defined as being complementary to the first chemical functionality via non-covalent hydrogen bonding. That is, the co-former’s second chemical functionality must be complementary to either a carboxamide, carbonyl, or amine functionality of an API via non-covalent hydrogen bonding. Second, the non-covalent hydrogen bonding between the first chemical functionality of the API and the second chemical functionality of the co-former must result in the formation of supramolecular synthons.” slip op. at 21

But Patent Owner and Dr. Howell do not explain how a barcode could be used in the devices depicted in Figures 16–18, which place the detection means 2.4.2 on the outer circumference of the flange (not its underside) and rely on toothed-rings physically interacting with either the chamber, retaining arms, or a pinion. Ex. 1047, 12:22–31, 13:8–18. Indeed, the second German priority application explains that means 2.4.2 physically interacts with retaining arms 30 (embodiments of Figures 16 and 17) or a pinon (embodiment of Figure 18), and if means 2.4.2 were not present in these embodiments the capsule would either “drop through into a waste container” or could not be inserted through the insertion shaft. Id. at 12:22– 27, 13:9–12, 13:16–35 (noting that in the embodiment disclosed in Figure 18 a pinon interacts with means 2.4.2 and only when means 2.4.2 “is formed complementary to the teeth of the means” can the capsule be inserted). At no point does the second German application identify means 2.4.2 as a barcode or suggest a barcode could be used as the detection means. The second German application also states that A person skilled in the art is also aware that for example the insertion shaft may also contain a sensor, for example a camera, clear, however, that element 27 is part of the brewing chamber, and not the capsule. Ex. 1047, 12:27–31, 13:5–8, 13:21–26, 15:36. Thus, we are not persuaded that the toothed ring is in fact on the bottom side of the flange. which senses the shape of the means 2.4.2. For example, it would be possible, in the present case, for the shape of the teeth and/or the spacing between the same to be sensed. This signal, in turn, is passed to a control means, which frees, for example, the brewing chamber if the capsule is the correct one. Ex. 1047, 14:11–19. Again, despite using a camera to determine if a capsule is “the correct one,” the second German application does not suggest using a barcode in place of the toothed-ring structure, or suggest moving the location of the detection means 2.4.2 from the outer surface to the underside of the flange. This reinforces that the inventors did not contemplate using a barcode in the embodiments depicted in Figures 16–18.” slip op. at 23

Conversely, Dr. Howle has limited experience in this field and is not one of ordinary skill in the art.

Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence.

    “We disagree. It is clear from the plain language of claim 1 that the claimed “cleaning composition” is a composition for cleaning that includes four named components and has a specified pH. Ex. 1001, 29:2–9. The ’329 patent specification unambiguously teaches that the cleaning composition is for removing residues from semiconductor substrates. Id. at 1:23–29, 2:10–12, 2:17–33, 15:52–55. Although the ’329 patent describes a cleaning composition that comprises a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water, we see no reason to construe the term “cleaning composition” itself to require these components. Claim 1 expressly recites expressly including or precluding a chelating agent or a metal corrosion inhibitor. Ex. 1001, 29:2–9. The Federal Circuit advises that the specification “is not a suitable substitute for, nor can it be used to rewrite, the chosen claim language. ‘Specifications teach. Claims claim.’” SuperGuide, 358 F.3d at 875 (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 n. 14 (Fed. Cir. 1985) (en banc)). The ’329 patent specification does teach a cleaning composition that includes a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water, but claim 1 is directed to a cleaning composition that expressly requires only a subset of those components. Patent Owner’s proposed construction would effectively rewrite the claim by adding unclaimed components, which we decline to do under the guise of claim construction. See id.

    “that Petitioner establishes that the ’329 patent does not provide sufficient written description support for the challenged claims. Pet. 15–43; Ex. 1007 ¶¶ 56–82. More specifically, we find that the ’329 patent does not reasonably convey to a POSA that the inventor was in possession of cleaning compositions that do not include a chelating agent or a metal corrosion inhibitor. There is no dispute, on this record, that the ’329 patent specification explicitly teaches that a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water are mandatory components of the cleaning composition described therein. PO Resp. 15 (Patent Owner agreeing with Petitioner that “[t]he ’329 patent’s disclosure is unambiguously explicit regarding mandatory components of the cleaning compositions described therein.” (citing Pet. 17; Ex. 1007 ¶¶ 56–57) (emphasis omitted, alteration in original)); see Ex. 1001, 3:47–48, 3:62–64, 10:24–26, 10:66–11:2, 12:3–4; Ex. 1007 ¶¶ 56–67. Claim 1, however, does not require that the cleaning composition include a chelating agent or a metal corrosion inhibitor. Ex. 1001, 29:2–9. Therefore, establishing proper written description support for claim 1 requires more than showing that the inventor was in possession of a cleaning composition that includes a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water; the ’329 patent must also show that the inventor was in possession of a cleaning composition that includes only a redox agent (hydroxylamine), an organic solvent (an alkylene glycol), water, and an alkanolamine.

    “that “using the [designated layer] as a mask” encompasses a situation in which the modified mask pattern 358, having “edges that are in line and flush” with second resist pattern 359, is therefore used as a mask. For the reasons discussed above, we do not agree with Patent Owner that “us[ed] . . . as a mask” necessarily encompasses such a situation. See supra Section II.C.2. We note that the application of our construction would not preclude layer 358 as shown in Patent Owner’s modified Figure 16(a) from ever being a mask when etching layer 355, if it were in fact described as such. However, there is no such description in the Japanese priority application; instead, the corresponding discussion identifies only second resist pattern 359 as a mask for this etching step. See Ex. 1014 ¶ 96 (“If there is a concern that the second resist pattern 359 has been misaligned with the first resist pattern 357, then the mask pattern 358 should be dry-etched using the second resist pattern 359 as a mask before the second silicon dioxide film 355 is dry-etched using the second resist pattern 359 as a mask.” (emphasis added)). Further, as noted by Petitioner (Reply 10–11), the corresponding discussion is, at best, ambiguous as to whether mask pattern 358 is “used as a mask” for etching layer 355.

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.’”). Thus, “composed of” means either “consisting of” or “consisting essentially of.” Id. The term “consisting of” prohibits any 4 <111> and <002> are indices that pertain to an orientation or direction of crystals. Ex. 1003 ¶51. unspecified components. Id. (citing PPG Indus. v. Guardian Indus. Corp., 156 F.3d 1351, 1354 (Fed. Cir. 1998)). The term “consisting essentially of” prohibits only unspecified components that materially affect the basic and novel characteristic(s) of a claimed invention. Id. (citing Atlas Powder Co. v. E.I. du Pont De Nemours & Co., 750 F.2d 1569, 1574 (Fed. Cir. 1984)). By arguing that “being composed of” means “consisting essentially of” as opposed to “consisting of,” Patent Owner argues for broader claim scope. 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

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “1. Level of Ordinary Skill in the Art The parties propose similar definitions of the level of ordinary skill in the art. Petitioner argues that a person of ordinary skill in the art would have had “an equivalent of a Master of Science degree from an accredited institution in electrical engineering, materials science, or physics, or the equivalent, a working knowledge of semiconductor processing technologies for integrated circuits, and at least two years of experience in semiconductor processing analysis, design, and development.” Pet. 10–11 (citing Ex. 1003 ¶64). Patent Owner argues that such an individual would have had “at least a Bachelor’s degree in Electrical, Materials, Mechanical, or Chemical Engineering, or a related degree, and at least two years of experience working in semiconductor processing and fabrication, semiconductor equipment manufacturing, or semiconductor materials.” PO Resp. 18 (citing Ex. 2011 ¶24). Neither party explains in detail why its proposed level of ordinary skill in the art should be adopted nor how the different levels affect the parties’ analyses. Based on the evidence of record, including the testimony of the parties’ declarants, the subject matter at issue, and the prior art of record, we adopt Petitioner’s definition.” slip op. at 16

    “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

    “obvious over Ding in view of Zhang. Patent Owner’s proposed claims 11 and 12 are unpatentable because they introduce limitations—nitrogen throughout the first film (claim 11) and nitrogen at the upper surface of the first film (claim 12)—that are met by the very references asserted in the ground of unpatentability involved in this inter partes review. 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
