    “We find this argument unavailing. Rather, we agree with Petitioner and determine that the claim language does not mean that the sub-optics are angled but instead means that they each view a subject from different angles. Ex. 1020, 11:43–45; Pet. Reply 7. Specifically, this limitation recites that the two sub-optics are “configured for a simultaneous acquisition of two views according to two different angles.” Ex. 1020, 11:43–45. Notably, “according to two different angles” directly follows “two views,” rather than directly following “configured.” Id. And “view” means “[a] scene or an arrangement of subject material for a photograph,” according to a technical dictionary provided by Patent Owner. Ex. 2014,6 210 (defining “view”). In other words, the term “view” itself refers to viewed subject material—a target subject.” slip op. at 13

Moreover, the parties agree that which definition we adopt does not substantively impact our analysis of the parties’ arguments concerning unpatentability. Tr. 29:19–30:9, 75:20–25.

    “Otto rely on Treuillet for what the Treuillet reference teaches to a person having ordinary skill in the art at the relevant time. Treuillet’s suggestions to a person having ordinary skill in the art remain relevant even if Treuillet were factually incorrect in some respects. Second, even if considered hearsay, Dr. Otto properly relied on Treuillet. Opp. Mot. Excl. 4–7. Under Federal Rule of Evidence 703, an expert may rely on facts and data that “need not be admissible,” including hearsay (double or otherwise). Here, the evidence supports that Treuillet was published in an independent, respected, and peer-reviewed IEEE journal. Id. at 5–6 (citing evidence regarding reliability of the IEEE journal). In addition, we find unavailing Patent Owner’s arguments concerning “Reference 45.”5 Mot. Excl. 3–5; Reply Mot. Excl. 1–5. Rather, we find that it is appropriate for an expert also to rely on the sourcing in article published in such an IEEE journal. Thus, Treuillet is the kind of evidence we would expect an expert witness or person having ordinary skill in the art to rely upon, and Dr. Otto was entirely reasonable on relying on Treuillet in forming his opinions Third, even if Treuillet were inconsistent with other evidence, such as Plassmann, this issue would go to the credibility of Dr. Otto’s testimony and the weight given to it in deciding ultimate issues of fact rather than admissibility in the first instance.

    “Petitioner persuasively argues that Treuillet teaches that the Plassmann MAVIS II device may take acceptable wound photographs from 65 centimeters to 95 centimeters (within its “depth of field”). Pet. 36; Ex. 1003 ¶ 113; Ex. 1016, 755. A person of skill in the art would have understood that acceptable medical wound photographs would have to be adequately focused and that Treuillet, therefore, suggests a depth of field from 65 centimeters to 95 centimeters for the Plassmann device. Ex. 1003 ¶ 113 (explaining that a person of skill in the art would understand that Plassmann has an expanded depth of field because it can “accurately image a subject at multiple positions”). Petitioner then relies on Staller as teaching multiple light beamers to define more than one imaging position within a depth of field. Pet. 41–42; Ex. 1006, Fig. 4, 2:29–34, 5:56–6:2. Staller teaches plurality of pairs of light beams that “intersect at a different repeatable distance from the diffuser body.” Pet. 23; Ex. 1006, code (57), 2:29–32, 5:13–15; see also id. at 5:56– 6:2 (“[T]wo pairs of light beam emitters . . . may be used to provide three or four separate pairs of intersecting bea[m]s and three or four corresponding repeatable distances for diffuser 10.”). In other words, Staller teaches having at least two distinct predefined distance positions for the camera. Ex. 1006, code (57), 2:29–32, 5:13–15, 5:56–6:2. The advantage of the plurality of pairs of light beams is taught by Staller: repeatability. Ex. 1006, 6:10–15 (referring a concern for “repeatable scale” to “improve[] the usefulness of close range photographs for medical” applications). Petitioner persuasively argues that a person of skill in the art would have been motivated to predefine two distances from a device in order to provide for varying levels of magnification.

    “Petitioner’s proposal is too broad. PO Resp. 8. For example, a person who merely installs solar panels for three years (satisfying “professional experience in solar energy”) while having some familiarity with module manufacturing would not be of ordinary skill in the design aspects of the ’060 patent as, for example, reflected by the claims at issue and the ’060 patent’s text and figures. See, e.g., Ex. 1001, Figs. 2a, 2b, 3a, 3b, 4a, 4b, 3:22–7:44. On the other hand, we also determine that Patent Owner’s proposal is too narrow. A person could, for example, have ordinary skill in the art of the ’060 patent by virtue of non-professional experience (for example, academic experience). When assessing relevant experience, research work done for a university (beyond mere classroom study) would have been just as valuable as research work done for a corporation. Also, ordinary skill in the art could be demonstrated by work that requires understanding of the ’060 patent’s field even if not “designing, developing, and/or researching” in the field itself. We, thus, determine that a person of ordinary skill in the art of the ’060 patent would have been someone with a bachelor’s degree in electrical engineering, applied physics, or the like, and at least two years of (a) experience designing, developing, and/or researching in the field or (b) experience in solar energy that required an understanding of the ’060 patent’s field.

In particular, Patent Owner argues that a person of ordinary skill in the art via one or more cross-connectors” and that “a” meaning “one” in claim 4 is necessary for claim 4 to further limit claim 1. Id. Petitioner argues that “a” means “one or more.” Pet. Reply 2–4. We agree with Petitioner. The ’040 patent explicitly defines “a” consistently with Petitioner’s position by stating that “it should be noted that the term ‘comprising’ does not exclude other elements or steps and the ‘a’ or ‘an’ does not exclude a plurality.” Ex. 1001, 7:62–63. The ’040 patent’s explicit definition is consistent with typical usage of “a” in this patent law context. See, e.g., KCJ Corp. v. Kinetic Concepts, Inc., 223 F.3d 1351, 1356 (Fed. Cir. 2000) (explaining that “a” in patent parlance means “one or more” for open-ended claims reciting the transitional phrase “comprising”). Patent Owner’s argument regarding claim construction is unpersuasive because Claim 4 further limits claim 1 by explicitly requiring first and second crossconnectors; claim 1 does not recite a “cross-connector.” Ex. 1001, 8:2–22. Thus, we construe “a” in this context as meaning “one or more.”” slip op. at 15

And, although there are no bright-line rules for the amount of disclosure needed in an unpredictable art, that amount “necessarily changes with each invention” and “changes with progress in the field.” Ariad, 598 F.3d at 1351. Here, we find that the art of AAC was unpredictable and that a heat-transfer composition for AAC required specific technical features that were unpredictable and unexpected. Thus, we conclude that the ’525 application requires a more-detailed disclosure than would be required in a predictable field to adequately demonstrate possession of a heat-transfer composition consisting essentially of HFO-1234yf and PAG for use in AAC. (iii) Disclosure in the ’525 Application With these background findings in mind, we now turn to the four corners of the ’525 application—and we find that the ’525 application does not contain the detailed disclosure needed in this case to reasonably convey possession of a heat-transfer composition consisting essentially of HFO- 1234yf and PAG for use in AAC.” slip op. at 37

Accordingly, we find that Petitioner’s evidence, together with Patent Owner’s concessions, demonstrates by a preponderance of evidence that the claimed subject matter of the ’017 patent was in commercial use before its March 26, 2014, effective filing date.

Ex. 1002 ¶ 403.

    “We agree with Petitioner that the ’525 application’s statement that the compounds are “adaptable for use” weighs against a finding of adequate written description. First, “adaptable for use” is vague, as Dr. Bivens acknowledges. See Ex. 1177, 151:15 (testifying that “adaptable for use can have a wide range of meaning”). Second, the ’525 application gives no direction on how a skilled artisan would need to adapt any particular composition for use in AAC, or even if any “adaptation” was necessary.

But providing context for the limitations in the claim body is tantamount to reciting “a purpose or intended use for the invention,” which typically does not limit the claims. TomTom, Inc. v. Adolph, 790 F.3d 1315, 1323 (Fed. Cir. 2015). The claim here does not rely upon the preamble for antecedent basis of any limitation in the claim body. E.g., Ex. 1001, 8:13–24. Moreover, nothing about the preamble adds to the recitation of the invention defined by the claim body—deleting the preamble would not affect the steps of the claimed invention. Thus, the relationship between the preamble and the claim body indicates that the preamble recites a nonlimiting intended use. TomTom, 790 F.3d at 1324 (citing Am. Med. Sys., Inc. v. Biolitec, Inc., 618 F.3d 1354, 1358–59 (Fed. Cir. 2010)).” slip op. at 7

    “reduces resistivity with additional layers. Pet. Reply 15–16. And Petitioner identifies additional record evidence to support that annealing can reduce resistivity and smooth the silicon surface. Id. (citing Ex. 1008, 3:37–39; Ex. 1005, 1:58–2:1; Ex. 1014, Fig. 2, 660–62 (discussing 20–30% reduced sheet resistance for films annealed before ion implantation); Ex. 1013, 181 (“The emitter resistance of annealed devices is considerably lower than unannealed ones.”); Ex. 1015, 259 (“[A] controlled annealing treatment is necessary to convert the amorphous film into a smooth polycrystalline film.”). Patent Owner argues that Petitioner’s additional citations and evidence are too late, and should have been raised in the Petition. PO Sur-Reply 15. We do not agree. Petitioner reasonably responds to an issue discussed in the Institution Decision and Patent Owner Response. See Inst. 8; PO Resp. 30–31. Dr. Leburton’s testimony cited in the Petition sufficiently established Petitioner’s contention to permit elaboration during the trial, and the full record supports that annealing Yoon’s silicon substrate as taught by Chern would have reduced interface roughness and therefore the resistivity between the polysilicon and additional layers. That benefit would have sufficiently motivated skilled artisans to make the asserted combination. Even if we were to discount that aspect of Petitioner’s proffered motivation, however, we determine that reduced susceptibility to peeling also would have motivated skilled artisans to anneal Yoon’s substrate. Petitioner relies on Chern’s statement that “[p]erforming the polysilicon annealing step prior to forming a diffusion barrier layer has been experimentally proven to reduce the subsequently formed diffusion barrier layer’s susceptibility to peeling.” Ex. 1006, 3:31–38; Pet. 14–15. Patent Owner argues that Chern’s disclosure of reduced peeling susceptibility relates only to depositing a barrier layer on the annealed polysilicon. PO Resp. 33–34. Patent Owner identifies Dr. Leburton’s testimony that the modification would reduce susceptibility of Yoon’s tungsten nitride barrier layer from peeling, notwithstanding that a metal layer is between the polysilicon substrate and tungsten nitride layer. Id. at 34 (citing Ex. 2005, 67:23–68:6). While Patent Owner focuses on the tungsten nitride layer, we agree with Petitioner that the record supports reduced peeling for whatever material contacts the annealed substrate. Dr. Leburton testified that annealing a polysilicon substrate makes that material more “coherent and consistent” and improves its “contact with other materials.” Ex. 2005, 134:24–135:25. We agree with Petitioner that reducing peeling from the polysilicon substrate is a benefit to all upper layers, as they depend on the bottom layer remaining attached. See Pet. Reply 14–15. Thus, we conclude that skilled artisans had reason to anneal Yoon’s polysilicon substrate both to reduce additional layers’ susceptibility to peeling, and also to reduce interface roughness and resistivity.” slip op. at 13

    “We do not read Weimer as teaching away from forming a titanium silicide barrier layer. Weimer expressly states that doing so may result in agglomeration, and that such agglomeration can increase resistivity. Ex. 1008, 3:8–10. Those possibilities do not convey that titanium silicide is unlikely to work, only that it introduces additional complications. See In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994) (“The degree of teaching away will of course depend on the particular facts; in general, a reference will teach away if it suggests that the line of development flowing from the reference’s disclosure is unlikely to be productive of the result sought by the applicant.”). To that point, although Weimer indicates a possible complication, Dr. Leburton explained that annealing would suppress the possible agglomeration. Ex. 2005, 136:21–137:13. As Petitioner points out, the combination in which Weimer’s teachings are used includes annealing the polysilicon layer. Pet. Reply 19.

    “does not explain how any of the supposed advantages of Feild are relevant to How-767 or how the combination would achieve these supposed advantages. Petitioner identifies reducing fabrication steps, eliminating polishing steps, and high electromigration performance as benefits of Feild’s fabrication method. See Pet. 63 (citing Ex. 1011, 2:48–3:10; Ex. 1006 ¶ 149). Dr. Lall’s cited testimony identifies these advantages compared to the prior art techniques discussed in Feild that use additional polishing steps, multiple-step processing, and the use of chemical mechanical polishing. See Ex. 1006 ¶ 149 (citing Ex. 1011, 2:16–32, 2:20–30, 2:48–3:10). Petitioner also asserts that How-767 presents Figure 1 as an exemplary cross-sectional view of a generic integrated circuit and never suggests that the precise structure of Figure 1 is required. See Pet. 65 (citing Ex. 1003, 1:21–22). On this basis Petitioner contends that a person of ordinary skill in the art would have understood that other cross-sectional interconnection arrangements could be used. See id. (citing Ex. 1006 ¶ 152). Petitioner asserts that a person of ordinary skill in the art would have understood that forming How-767’s routing structure according to the interconnect structure taught by Feild would involve a simple substitution of Feild’s cross-sectional interconnect structure for How-767’s exemplary cross-sectional interconnect structure to obtain predictable results. See id. (citing Ex. 1006 ¶ 153). Accordingly, we understand that Feild’s advantages of reducing fabrication steps, eliminating polishing steps, and high electromigration performance would be achieved by forming How-767’s routing structure according to Feild’s cross-sectional interconnect structure. In sum, based on the entire trial record, we determine that Petitioner sets forth sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to modify How-767 by “forming How-767’s routing structure according to the interconnect structure taught by Feild” in order to obtain the advantages of reducing fabrication steps, eliminating polishing steps, and high electromigration performance.

    “proposed combination with Kovatch. PO Resp. 37. According to the Federal Circuit, “[a] reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Mouttet, 686 F.3d 1322, 1333–34 (Fed. Cir. 2012) (quoting In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994)) (alteration in original). However, “the ‘mere disclosure of alternative designs does not teach away.’” Id. at 1334 (quoting In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004)). Indeed, “just because better alternatives exist in the prior art does not mean that an inferior combination is inapt for obviousness purposes.” Id. (citing Gurley, 27 F.3d at 553). Specifically, Patent Owner (PO Resp. 37), points to disclosure in Neal describing disadvantages of a keyword search strategy (e.g., “users must be familiar with the appropriate key word terms that are likely to yield the desired data records”) and disadvantages of a classification search strategy (e.g., “users may not always anticipate the proper classification of certain records, and may search the wrong categories for their desired database record”). Ex. 1007, 2:16–65. Neal then describes a “preferred embodiment” in which “the system manager will expand the scope of the search strategies from ‘exact’ string matches, along a continuum of search methodologies, including perhaps fuzzy logic strategies.” Id. at 7:14–17. According to Neal, “[t]he purpose of expanding the search strategies is to avoid the situation wherein the search fails to identify the desired item from any data set, and thereby drops into logical block 222 a negative search result is reported to the user.” Id. at 7:28–32. Patent Owner argues that “Neal advocates for employing a sequence of search algorithms from the narrowest to the most broad.” PO Resp. 38 (citing Ex. 1007, 7:56–58; Ex. 2059 ¶ 124). Patent Owner contends that Neal teaches away from a combination “that employs a single keyword matching search strategy.” Id. Patent Owner argues that Petitioner’s combination of Kovatch and Neal results in a system that only sequentially searches datasets using a single keyword matching search strategy, and not the cascading sequence of search methodologies described by Neal. Id. at 37–39. We do not agree with Patent Owner that Neal teaches away from a system that employs a single keyword matching search strategy. Indeed, Neal’s preferred embodiment expressly contemplates such a system. For example, Neal describes employing a first “exact string search” methodology to search a first data set (Figure 2, block 206). Ex. 1007, 6:34– 46. This appears to be what Patent Owner considers a “single keyword matching search strategy.” PO Resp. 37–38. Neal describes that if this search of the first data set does not yield a match, the system searches a second data set using a second search methodology (Figure 2, block 210). Ex. 1007, 6:47–52. However, in the preferred embodiment there is no requirement that the second search methodology in 210 must be different from the first search methodology in 206. For example, if the first preferred supplier did not yield an exact string match to the input search term, the same search methodology could be applied to a second preferred supplier’s catalog. Id. at 6:59–65. Thus, Neal expressly teaches using a single keyword search strategy on a first dataset and the same keyword search strategy on a second dataset, without necessarily employing a cascading sequence of different search methodologies.
