“To determine how a person skill in the art would determine if a shrink label is “recyclable” as recited in the independent claims, we look to how the Specification of the ’422 Patent describes or defines recyclable shrink labels. For example, the ’422 Patent states that PET shrink films are generally considered recyclable if no inks are retained on the film after a caustic wash cycle typically used in PET reclaiming processes. Ex. 1001, 6:61–65. The ’422 Patent further states that labels are fully recyclable if the polymers used are clear, preferably clear PET, and the labels include inks that can be washed off in a “typical PET recycling wash (caustic wash).” Id. at 11:44– 49; see also id. at 11:49–54 (describing embodiments in which the labels are free or substantially free of inks that cannot be washed off in a caustic wash or where the labels are free or substantially free of color plastics that cannot be recycled). The ’422 Patent further discusses “industry standards” for determining whether various embodiments of shrink labels are recyclable. See, e.g., id. at 11:29–53. For example, the Specification states that the “Association for Plastic Recyclers (APR) Critical Guidance Protocol for Clear PET Articles with Labels and Closures (PET-CG-02)” (Ex. 1005) can certify that a film is fully recyclable with a container or bottle. Id. at 11:34– 38. Additionally, the Specification states that labels “are recyclable according to the Evaluation of the Near Infrared (NIR) Sorting Potential of a Whole Plastic Article (SORT-B-01)” (Ex. 1010) and/or the “Evaluation of Sorting Potential for Plastic Articles Utilizing Metal, Metalized, or Metallic Printed Components (SORT-B-03)” (Ex. 1011). Ex. 1001, 11:39–44. The ’422 Patent further states that embodiments of the labels “are fully recyclable. For example, the labels may include inks that can be washed off in a typical PET recycling wash (caustic wash) and the polymers” are preferably clear PET. Id. at 11:44–48. The ’422 Patent thus provides various descriptions or standards to determine the recyclability of shrink labels. For the purposes of addressing the anticipation and obviousness grounds, we determine that any of these standards can be used to determine if a shrink label is “recyclable.” We note that our construction is preliminary and is based on the present record. We invite the parties to further the address the construction of “wherein the recyclable shrink label is recyclable with a PET container” during trial.” slip op. at 12

“filter comprises “a third set of layers on the second side, whether the third set of layers includes oxygen.” Ex. 1001, 10:41–49.

Pet. 7–8. Patent Owner agrees that this is the “literal” reading of the language, but contends that one of ordinary skill in the art “would have appreciated that this language was intended to read ‘wherein’ rather than ‘whether’” and that the claim requires that this set of layers must include oxygen.

“415 F.3d at 1314): “a first set of layers on the first side, wherein the first set of layers includes silicon and hydrogen” (claim 1) and “a first set of layers including silicon and hydrogen” (claims 9 and 15). Ex. 1001, 10:41–49, 10:65–11:4, 11:17–12:5. As the parties agree, these recitations are broadly worded. See Pet. 14 (describing the recitations of the claims as “broad” and directed to “layers of any material that has both ‘silicon and hydrogen’”); PO Resp. 42 (describing the claims as “simply specifying physical layers including silicon and hydrogen in them”), 44 (describing the disputed terms as “open-ended claiming of layers including hydrogen and silicon”). Despite this broad language, Patent Owner contends that we must read “layers including silicon and hydrogen” in conjunction with other limitations in the claims reciting a “near infrared bandpass filter.” PO Resp. 35–37 (citing Ex. 2001 ¶¶ 65–66). For purposes of our analysis, we limit “layers including silicon and hydrogen” to only materials suitable for NIR bandpass filters, as suggested by Patent Owner. We next examine the rest of the intrinsic evidence. The specification of the ’794 patent does not contain language that generally describes “layers including silicon and hydrogen.” Instead, the specification describes only layers of hydrogenated silicon: its abstract is directed to an “optical filter” that “includes a filter stack formed of hydrogenated silicon layers” (Ex. 1001, code (57)); the technical field of the invention is described as “relat[ing] to optical filters including hydrogenated silicon layers and to sensor systems comprising such optical filters” (id. at 1:20–23); the summary of the invention describes “the present invention” as an optical filter or sensor system “comprising” “a plurality of hydrogenated silicon layers” (id. at 2:57–3:19); and the detailed description begins with a hydrogenated silicon (Si:H) layers” (id. at 4:19–20). The specification only mentions silicon and hydrogen separately with respect to the disclosed sputter-deposition system “used to produce the hydrogenated silicon material.” Id. at 4:35–5:61, 7:10–19. In particular, the specification describes how “cathode 430 includes a silicon target 431, which is sputtered in the presence of hydrogen (H2), as well as an inert gas such as argon, to deposit the hydrogenated silicon material as a layer on the substrate 420.” Id. at 4:44–47. The specification also describes how altering the hydrogen flow rate in the deposition process affects the optical properties of hydrogenated silicon produced by the deposition system. See id. at 5:1–61. But the only end product described from the sputter-deposition process using silicon and hydrogen is hydrogenated silicon. See id. at 4:35–5:61, 7:10–19. As such, the specification does not provide any indication of materials beyond hydrogenated silicon that are within the scope of “layers including silicon and hydrogen.”” slip op. at 15

“hydrogen” defines a genus. The test for providing a written description that supports a genus claim is whether the description provides “either a representative number of species falling within the scope of the genus or in the art can ‘visualize or recognize’ the members of the genus.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1350 (Fed. Cir. 2010) (en banc). “Regarding whether common structural features must exist between a claim and a putative priority disclosure, those features must constitute the near-entirety of the structures being compared.” Regents of the Univ. of Minnesota v. Gilead Scis., Inc., 61 F.4th 1350, 1358 (Fed. Cir. 2023). Yet the patentees only disclosed hydrogenated silicon as a possible species. Indeed, the specification focuses on a singular example of a sputterdeposition system that is used to produce an improved hydrogenated silicon material. See Ex. 1017 ¶¶ 36–38. Patent Owner cites this deposition process as written description support for “the claimed layers containing silicon and hydrogen.” See PO Resp. 44. But this example supports only how to make hydrogenated silicon and does not include any indication about what other materials would be within the scope of the claimed genus. Under these circumstances, the specification’s disclosure of a single species is not an adequate number to show possession of the entire genus of “layers including silicon and hydrogen.” Beyond the disclosure of the sputter-deposition process for producing hydrogenated silicon, Patent Owner does not identify—and we cannot discern—any other examples of a “structure, formula, chemical name, physical properties, or other properties, of species falling within the genus sufficient to distinguish the genus from other materials.” Ariad, 598 F.3d at 1350. This is particularly noteworthy given that undisputed record evidence shows numerous other potential filter materials “including silicon and hydrogen.” See supra § II.D.1.a.

“The Trial Practice Guide states that “one petition should be sufficient to challenge the claims of a patent in most situations.” CTPG 59. “Two or more petitions filed against the same patent at or about the same time . . . may place a substantial and unnecessary burden on the Board and the patent owner and could raise fairness, timing, and efficiency concerns.” Id. (citing 35 U.S.C. § 316(b), which is identical to 35 U.S.C. § 326(b)). Although rare circumstances may necessitate two petitions, “the Board finds it unlikely that circumstances will arise where three or more petitions by a petitioner with respect to a particular patent will be appropriate.” Id. To help the Board determine whether multiple petitions are necessary, the Trial Practice Guide further instructs a petitioner filing multiple petitions challenging the same patent to explain “the differences between the petitions, why the issues addressed by the differences are material, and why identifies one petition that satisfies petitioner's burden under 35 U.S.C. § 314(a).” CTPG 59–60. Additionally, the Trial Practice Guide instructs the patent owner to “clearly proffer any necessary stipulations,” where the patent owner asserts that “the differences identified by the petitioner are directed to an issue that is not material or not in dispute.” Id. at 61. The patent owner may, for example, “seek to avoid additional petitions by proffering a stipulation that certain claim limitations are not disputed or that certain references qualify as prior art.” Id. In light of the particular facts before us, we decline to exercise our discretion to deny the Petition pursuant to 35 U.S.C. § 324(a) on the basis of the filing of two parallel petitions. In particular, we recognize that the two petitions do not include duplicate attacks on the basis of unpatentability over prior art, but rather break the issues into two distinct parts—prior-art based unpatentability challenges, in PGR2023-00012, and 35 U.S.C. §§ 101 and 112 challenges here. The usual considerations of fairness, timing, and efficiency do not weigh in favor of exercising our discretion to deny institution. In particular, the petitions were filed concurrently, which means that Petitioner did not gain a timing advantage that might otherwise occur if the petitions were filed serially. Additionally, the proceedings can be coordinated, and a similar or common schedule can be adopted. To the extent that Patent Owner argues (see Prelim. Resp. 55–56) that Petitioner was attempting to avoid providing a single stipulation that (upon institution) Petitioner will pursue neither section 103 grounds on certain art, as per the stipulation offered in PGR2023-00012, nor section 101 and 112 grounds as per the stipulation here (see Pet. 49), discretionary denial of this Petition would not provide such a stipulation. Because we institute both here and in is equivalent to our best understanding of Patent Owner’s desired stipulation “tak[ing] into account” the two Petitions. Accordingly, based on the particular facts and circumstances before us, we decline to exercise our discretion to deny the instant Petition under § 324(a) on the basis of the Petitioner’s filing of multiple petitions.” slip op. at 14

“However, Patent Owner’s arguments regarding the combination are directed towards a bodily incorporation of structures described in the references, rather than the combination of their teachings proposed by Petitioner.

Given the teachings in each reference and our direction that an ordinarily skilled artisan is a person of ordinary creativity, we find, on this preliminary record, that Petitioner has adequately shown that an ordinarily skilled artisan would have applied Lairson’s teachings regarding a short-pass filter with Erdogan or Tsai-133’s teachings concerning filter layers on both sides of a substrate used to form a bandpass filter. KSR, 550 U.S. at 421 (“A person of ordinary skill is also a person of ordinary creativity, not an automaton.”). Petitioner’s proposed combination does not involve adding the exact layers taught in Erdogan and Tsai-133 on the second side of the substrate to Lairson’s short-pass filter on the first side of the substrate. Pet. 33–34, 36– 39. Rather, Petitioner proposes, in one example, using the same materials for filter stacks on both sides of the substrate. Id. at 37–38. Thus, Patent Owner’s arguments that adding the second-side layers disclosed in Erdogan and Tsai-133 to the first-side layers of Lairson is not responsive to Petitioner’s proposed combination. Additionally, on the present record, we credit Petitioner’s declarant’s uncontroverted testimony that Lairson does not explicitly describe a bandpass filter with a long pass filter, and thus that one of ordinary skill would have looked to Erdogan and Tsai-133 for the technique of using a long-pass filter on the other side of the substrate. Id. at 34–37 (citing Ex. 1002 ¶¶ 152, 158). On the present record, and for the purposes of institution, Petitioner sufficiently shows that the combination of Lairson and either Erdogan and Tsai-133 teaches a near infrared band pass filter comprising a first set of layers on the first side, wherein the first set of layers includes silicon and hydrogen, and a second set of layers on the first side, wherein the second set of layers includes oxygen. Additionally, on the present record and for the purposes of institution, Petitioner sufficiently sets forth its showing with respect to the motivation to combine the teachings of Lairson with those of Erdogan or Tsai-133 as it proposes.” slip op. at 21

“declarant Dr. Madisetti, that McCarthy does not provide written description support for the ’005 claims. McCarthy makes no mention of virtual machines and there is nothing in McCarthy that would suggest to one of ordinary skill in the art that the applicants had in mind the use of virtual machines as an embodiment of their invention. Our determination is informed by our interpretation, discussed in Section III.C above, that “virtual machine” encompasses software that mimics or emulates at least the basic functionality of a computer processor, but that merely virtualizing a resource such as memory or I/O devices does not create a virtual machine. Patent Owner’s attorney arguments are unpersuasive as citing irrelevant examples of virtual machines that interact with physical resources such as a host computer, memory or I/O devices, but which nevertheless mimic or emulate at least the basic functionality of a computer processor, unlike the partitions of McCarthy, which physically contain computer processors. McCarthy narrowly describes physical partitions, which do not mimic or emulate a computer processor and are not virtual machines. We understand that the statement in McCarthy that the “present invention” may be “implemented in software” (at paragraph 57 of McCarthy) merely refers to the fact that such components as the PLM, WLM, and performance monitor are software modules running on physical processors. We also agree with Petitioner that the reference to virtual partitions in McCarthy refers to the possibility that a partition hardware can be located in more than one computer, and has nothing to do with the use of virtual machines. Reply 2. Nor are we persuaded that the possibility of more than one partition residing in a single computer means that the partitions must be virtual, given that multiple processors can be in a single computer and a single processor can be partitioned by physically allocating its resources to multiple processes. Ex. 1013, Figs. 1A, 1B, ¶¶ 4, 8. As Petitioner argues, the ’005 patent explicitly distinguishes virtual machines from partitions as two separate species of the computer domain genus: Although some representative embodiments have been described in terms of allocating physical resources between partitions, representative embodiments may allocate resources between any suitable computing domain. Another suitable computing domain is a virtual machine. Reply 2 (citing Ex. 1001, 13:37–41). Unlike the ’005 patent, McCarthy confines its disclosure to partitions, and makes no mention of a computer domains genus or a virtual machines species. Accordingly, we determine, on the current record and for purposes of this decision, that the information presented in the Petition demonstrates a reasonable likelihood that Petitioner will prevail in establishing that McCarthy is prior art to the ’005 patent claims.6” slip op. at 21

“declarant Dr. Madisetti, that McCarthy does not provide written description support for the ’005 claims. McCarthy makes no mention of virtual machines and there is nothing in McCarthy that would suggest to one of ordinary skill in the art that the applicants had in mind the use of virtual machines as an embodiment of their invention. Our determination is informed by our interpretation, discussed in Section III.C above, that “virtual machine” encompasses software that mimics or emulates at least the basic functionality of a computer processor, but that merely virtualizing a resource such as memory or I/O devices does not create a virtual machine. Patent Owner’s attorney arguments are unpersuasive as citing irrelevant examples of virtual machines that interact with physical resources such as a host computer, memory or I/O devices, but which nevertheless mimic or emulate at least the basic functionality of a computer processor, unlike the partitions of McCarthy, which physically contain computer processors. McCarthy narrowly describes physical partitions, which do not mimic or emulate a computer processor and are not virtual machines. We understand that the statement in McCarthy that the “present invention” may be “implemented in software” (at paragraph 57 of McCarthy) merely refers to the fact that such components as the PLM, WLM, and performance monitor are software modules running on physical processors. We also agree with Petitioner that the reference to virtual partitions in McCarthy refers to the possibility that a partition hardware can be located in more than one computer, and has nothing to do with the use of virtual machines. Reply 2. Nor are we persuaded that the possibility of more than one partition residing in a single computer means that the partitions must be virtual, given that multiple processors can be in a single computer and a single processor can be partitioned by physically allocating its resources to multiple processes.

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

“Tr. 114:15–115:18 (emphases added). Thus, we find that Patent Owner does not contest that a heat-transfer composition consisting essentially of HFO- 1234yf and PAG for AAC was in public commercial use before the March 26, 2014, filing date of the ’017 patent. 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. See Ex. 1002 ¶¶ 399–409. In particular, as to claims 1, 3–10, 12, 13, and 15–20, we credit Dr. Brown’s uncontested testimony that the refrigerant-lubricant AAC composition of the Ford Transit Custom Bus, the Mazda CX 5 (2.0i and 2.2D), and the Opel Mocca used HFO-1234yf and a PAG lubricant as early as 2012.

Id. at 2–3. Petitioner and Dr. Brown direct us to the Sevice Guide’s entries calculations, which show that the Ford Transit Custom Bus had an AAC refrigerant-lubricant composition of 26.7% of PAG lubricant and 73.3% of HFO-1234yf (Ex. 1002 ¶ 401 (citing Ex. 1013, 38)); the Mazda CX 5 2.0i had 16.7% PAG lubricant and 83.3% HFO-1234yf (Ex. 1002 ¶ 402 (citing Ex. 1013, 55)); the Mazda CX 5 2.2D had a 17.5% PAG lubricant and 82.5% HFO-1234yf (id.); and the Opal Mocca had 11.6% PAG lubricant and 88.4% HFO-1234yf (Ex. 1002 ¶ 402 (citing Ex. 1013, 70)). As to dependent claims 2, 11, and 14, which all require that the lubricant is present “in an amount from about 30% to about 50% weight,” we credit Dr. Brown’s uncontested testimony that the refrigerant-lubricant composition of the Ford Transit Custom Bus recited lubricant amount. Ex. 1002 ¶ 403. In particular, we agree with Dr. Brown that, because the lubricant accounts for 26.7% of the AAC refrigerant-lubricant composition in the Ford Transit Custom Bus, the lubricant makes up “about 30%” of the refrigerant-lubricant composition as claimed.

“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. We find that such a teaching is important in this case to show that the inventors had possession of the claimed invention, given our findings above that the art of AAC was unpredictable and that a heat-transfer composition for AAC required specific technical features that were unpredictable and unexpected. For completeness, we again reject Patent Owner’s argument that “[t]o show the inventors possessed claim 1 requires no more” than the statement in the written description that “‘the compositions of the present invention are believed to be adaptable . . . with or without system modification.’” PGR12 Resp. 27–28 (quoting Ex. 1001, 7:4–8).
