“C. Level of Ordinary Skill in the Art Factors pertinent to determining the level of ordinary skill in the art include (1) the educational level of the inventor; (2) the type of problems encountered in the art; (3) prior-art solutions to those problems; (4) the rapidity with which innovations are made; (5) the sophistication of the technology; and (6) the educational level of workers active in the field. Envtl. Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696–97 (Fed. Cir. 1983). Not all factors may exist in every case, and one or more of these or other factors may predominate in a particular case. Id. These factors are not exhaustive, but merely a guide to determining the level of ordinary skill in the art. Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007). Moreover, the prior art itself may reflect an appropriate skill level. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Petitioner asserts that a person of ordinary skill in the art at the ’336 patent’s effective filing date would have had “a bachelor’s degree in mechanical engineering, electrical engineering, optics, or physics with at least three years of experience working in the design of LED lights or lighting fixtures; a master’s degree in one of the above disciplines with at least two years of experience; or equivalent experience.” Pet. 14 (citing Ex. 1004 ¶¶ 26–29). Dr. Eden’s testimony supports Petitioner’s assertion. See Ex. 1004 ¶¶ 27–28. Patent Owner “adopts for purposes of this proceeding only” Petitioner’s description of an ordinarily skilled artisan.

- Obviousness (§103) › Objective indicia / secondary considerationsObjective indicia no nexusDecided for petitioner
“Alleged Objective Indicia of Nonobviousness (i) General Principles Before reaching a conclusion about obviousness, we consider evidence concerning objective indicia of nonobviousness. See Apple, 839 F.3d at 1048. For such evidence to have substantial weight, “its proponent must establish a nexus between the evidence and the merits of the claimed invention.” ClassCo, Inc. v. Apple, Inc., 838 F.3d 1214, 1220 (Fed. Cir. 2016); see Ancora Techs., Inc. v. Roku, Inc., 140 F.4th 1351, 1361 (Fed. Cir. 2025) (noting that the Board did not err by requiring “a nexus to the challenged claims as opposed to the patent as a whole”). “[T]here is no nexus unless the evidence presented is ‘reasonably commensurate with the scope of the claims.’” ClassCo, 838 F.3d at 1220 (quoting Rambus Inc. v. Rea, 731 F.3d 1248, 1257 (Fed. Cir. 2013)). The patentee “bears the burden of showing that a nexus exists.” WMS Gaming, Inc. v. Int’l Game Tech., 184 F.3d 1339, 1359 (Fed. Cir. 1999). A rebuttable presumption of nexus arises “when the patentee shows that the asserted objective evidence is tied to a specific product and that product ‘embodies the claimed features, and is coextensive with them.’” Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (quoting Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1072 (Fed. Cir. 2018)). Whether a rebuttable presumption of nexus arises “turns on the nature of the claims and the specific facts.” Teva Pharms. Int’l GmbH v. Eli Lilly & Co., 8 F.4th 1349, 1362 (Fed. Cir. 2021). The presumption analysis should consider the unclaimed features in the product tied to the objective evidence to assess their significance and impact on the correspondence between the patented invention and the product. Quanergy Sys., Inc. v. Velodyne Lidar USA, Inc., 24 F.4th 1406, 1418 (Fed. Cir. 2022). When, “for example, the patented invention is only a small component of the product tied to the objective evidence, there is no presumption of nexus.” Henny Penny Corp. v. Frymaster LLC, 938 F.3d 1324, 1333 (Fed. Cir. 2019). Absent a presumption of nexus, the patentee may prove nexus by” slip op. at 76

“On this record, we are persuaded that Petitioner adequately establishes that Usui discloses all of the limitations of claim 1. Usui discloses that aluminum or aluminum alloy layer 15 is in electrical contact with titanium underlayer 13, and titanium nitride layer 14 is located “intermediate the [titanium underlayer] 13 and the aluminum or aluminum alloy layer 15” to prevent “reaction between the aluminum layer 15 and underlayer 13.” Ex. 1004, 3:27–29, 3:38–41, 3:58–63. Usui further discloses that “a capping layer is provided above layer 15,” and that “[p]referred capping layers are titanium nitride and combinations of as layer 18 of a group IVA metal, preferably titanium with a titanium nitride layer 19.” Id. at 3:67–4:6. Usui teaches that titanium nitride layer 19 is about 150 to 800 Å thick, and that the thickness of titanium underlayer 13 is between about 90 to 110 Å. Id. at 3:31–33, 4:6–8. Usui also teaches that the interconnect metallurgy structures described therein “exhibit[] enhanced electromigration characteristics” and “are especially useful for forming electrical connections or wiring such as between active and/or passive devices of an integrated circuit structure.” Id. at 1:8–14. Usui’s description of a plurality of metal layers (layers 13–18) and a capping layer formed over the plurality of metal layers (layer 19), along with its description of the structure’s usefulness for forming electrical connections in an integrated circuit structure, is sufficient, on this record, to establish that Usui discloses “an electrode stack including a plurality of metal layers and a capping layer formed over said plurality of metal layers” as recited in claim 1. Usui’s teaching that the capping layer is a refractory metal nitride (titanium nitride) that has a thickness (150–800 Å) greater than the bottommost layer of the plurality of metal layers (layer 13, 90–110 Å), sufficiently establishes, on this record, that Usui discloses the “said capping layer consisting only of a refractory metal nitride, said refractory metal nitride forming a top of said electrical contact and having a thickness greater than that of a bottommost layer of said plurality of metal layers” limitation of claim 1.” slip op. at 11

“Exhibits 1013 and 1014 are also not admissible as expert testimony because Mr. Wirén is not “qualified as an expert by knowledge, skill, experience, training, or education.” Fed. R. Evid. 703. “To offer expert testimony from the perspective of a skilled artisan in a patent case—like for claim construction, validity, or infringement—a witness must at least have ordinary skill in the art.

Mr. Wirén does not meet our definition of a person of ordinary skill in the art. See Section II.B, supra. That definition is based on the undisputed testimony of Messrs. Zotterman and Klass. Ex. 1003 ¶ 24; Ex. 2003 ¶ 26. Although Mr. Wirén has a Master’s of Science in chemical engineering, he lacks any experience or specialization in paperboard manufacturing.

“A claim construction that excludes a particular element is viewed as a “negative limitation.” Ethicon LLC v. Intuitive Surgical, Inc., 847 Fed. App’x 901, 907 (Fed. Cir. Mar. 15, 2021). “[S]uch exclusions must find support either in ‘the words of the claim’ or through an ‘express disclaimer or independent lexicography in the written description that would justify adding that negative limitation.’” Id. (citing Omega Eng’g, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed. Cir. 2003); CCS Fitness, Inc. v. Brunswick Corp., 288 F.3d 1359, 1366–67 (Fed.

(citing Thorner, 669 F.3d at 1365). Similarly, disclaimer or disavowal requires that the specification or prosecution history demonstrate that the invention does not include a particular feature. Id.

“a contact surface of said thermo-roller is heated to an elevated temperature of at least 250°F.” Petitioner shows persuasively that the temperature limitation is taught by the combination of Fugitt and Papermaking. Pet. 32–34. Fugitt discloses that “[t]he rolls of the calender may be steam heated.” Ex. 1004 ¶ 26. In a section titled “Heated Rolls,” Papermaking discloses that “Steam can be used up to 170°C [338°F] surface temperature.” Ex. 1010, 95, 98. Petitioner is thus correct that, “[w]hile Fugitt teaches that a hot calender may be steam heated, Papermaking clarifies that one of ordinary skill in the art would understand that steam heated thermo-rollers may reach up to 338°F.” Pet. 36. Based on these disclosures, we are persuaded by Mr. Zotterman’s testimony that it would have been “obvious to heat the thermo-roller of Fugitt to at least 250°F.” Ex. 1003 ¶ 159. combine Fugitt and Papermaking because of Papermaking’s status as a “trusted handbook[],” because both references disclose a method of manufacturing a paperboard structure with hot calendering,” and “because of the known advantages of heated rollers.” Pet. 36–37; Ex. 1003 ¶¶ 157, 159, 162. Petitioner’s contention is supported by Papermaking’s disclosures that, for cartonboard, “[p]recalendering is used before the coater to reduce roughness and porosity” and “[h]igh thermo roll temperatures (in some cases over 200°C) result in bulk savings because of the temperature gradient.” Ex. 1005, 80–82; see also Pet. 38; Ex. 1003 ¶ 164 (citing these disclosures). Papermaking’s disclosed range of “up to 170°C [338°F]” for steam- heated rolls (Ex. 1010, 98), overlaps the claimed range of “at least 250°F.” Patent Owner agrees. Tr. 27:11–13. “If the relevant comparison between a disputed claim limitation and the prior art pertains to a range of overlapping values, ‘. . . even a slight overlap in range establishes a prima facie case of obviousness.’” Genentech, Inc. v.

“the claim must be given their plain meaning unless the plain meaning is inconsistent with the Specification. In re Zletz, 893 F.2d 319, 321 (Fed. Cir. 1989). Additionally, ordinary, simple English words whose meaning is clear and unquestionable are to be construed to mean exactly what they say–– absent, of course, any indication that their use in a particular context changes their meaning. Chef America, Inc. v. Lamb-Weston, Inc., 358 F.3d 1371, 1372 (Fed. Cir. 2004). The abstract of the ’646 patent describes isolating and preserving cells from bodily fluids “for cellular analysis” and “genomic studies.” Ex. 1001, code (57). In the field of the disclosure portion of the ’646 patent, cells isolated from bodily fluids are preserved “for studies in any of: functional genomic and epigenetic studies, and biomarker discovery.” Id. at 1:25–29. In the background section, the ’646 patent describes the interest in “large-scale epigenetic research” for the purpose of “understanding the mechanisms of gene-environment interactions” suggesting that “epigenetic mechanisms may provide a molecular memory of environmental experiences.” Id. at 1:60–67. The background section further describes the challenges of collecting bodily fluids, such as saliva, is that it is a digestive fluid that can be rich in proteases and that existing solutions used to stabilize cells from blood, which is a transporter fluid, “will not protect cells from proteases found in some bodily fluids, such as saliva.” Id. at 3:24–36, 4:43–47. The detailed description section of the ’646 patent discloses “a solution for preserving cells in one or more bodily fluids, such as saliva and urine” that “may be beneficial for further separation into cell types and downstream molecular analysis” and “allows for storage of cells in the bodily fluid to retain their antigenicity and cellular architecture.” Id. at 16:9–15. The Specification describes some embodiments of solutions for preserving cells in one or more bodily fluids where the solutions contain a chemical fixing agent, a protease inhibitor, an antimicrobial agent, serum proteins, and are buffered to preferred pH ranges. Id. at 16:15–22. Thus, the plain meaning of “preserving a biological sample,” consistent with the ’646 patent disclosure focused on maintaining the architecture of cells contained in a bodily fluid that may include digestive proteases for further study downstream, is “preserving the integrity of a cell contained in a bodily fluid sample.”” slip op. at 15

RulingsFinal written decision- ExcludeMotion to exclude, deniedDenied
“Patent Owner’s argument is unpersuasive because the Krames declaration addresses the Patent Owner Response and is relevant to the issues at hand. We start with an important observation: claim 21 (the only independent claim at issue) is an apparatus claim; the claim is directed to a “semiconductor light source.” Ex. 1001, 9:52. One requirement of this apparatus is that it comprise “at least one semiconductor chip” (id. at 10:1) where the “at least one semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts.” Id. at EPRC, 1:34–36. As we explain when addressing claim construction, infra, we adopt Patent Owner’s proposed construction of “a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as meaning “at least one LED chip is capable of emitting light greater than about 40 milliwatts.” See Section III.D, infra (emphasis added). Because of these recitations, Petitioner bears the burden of establishing that the prior art teaches or suggests a semiconductor chip “capable of emitting light greater than about 40 milliwatts.” As explained herein, we determine that in the Petition, Petitioner met this burden by establishing by a preponderance of the evidence that the Krames reference teaches an LED chip that has this capability. Pet. 54 (quoting Ex. 1008, 10). Notably, claim 21 does not require actual operation of anything at greater than 40 milliwatts because claim 21 is not a method claim. Petitioner never had a burden of establishing a method of running the Krames reference’s LED at this power output within a semiconductor light source.” slip op. at 12
- Skill levelSkill level patent owner adoptedDecided for patent owner
“We agree with Patent Owner that the challenged claims relate to light fixtures, LED packaging, and LED chip layer structure and that the ’961 patent claims reflect “a hybrid of the light bulb art and semiconductor art.” Resp. 19. The prior art of record, for example, Begemann, likewise reflects “a hybrid of the light bulb art and semiconductor art.” Id. (quoting Pet. 28). Petitioner’s expert, Dr. Lebby, agreed that a person having ordinary skill in the art would need to be “familiar with thermal issues.” Ex. 2015, 26:15– 28:16. While Petitioner’s proposed description of a person having ordinary skill in the art could, in some instances, be sufficient to qualify a person as having ordinary skill, Patent Owner’s proposal is a more complete and accurate description of the level of skill commensurate with the scope of the challenged ’961 patent claims. Patent Owner’s description appears consistent with the prior art and patent specification before us and is supported by witness testimony. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself may reflect an appropriate level of skill). For the purpose of this Decision, we adopt Patent Owner’s description.

“Petitioner is permitted a “limited opportunit[y]” to present new evidence in or with its Reply, as long as that new evidence is “responsive to the prior briefing” and does not constitute “changing theories after filing [the] petition.” Hulu, LLC v. Sound View Innovations, LLC, IPR2018- 01039, Paper 29, at 14–15 (PTAB Dec. 20, 2019) (precedential). Here, both of the arguments that Patent Owner alleges are new—the argument that Voswinckel JESC and Voswinckel JAHA were presented publicly and the argument that these references were cited in other publicly available references—respond to Patent Owner’s argument in the Patent Owner Response that Voswinckel JESC and Voswinckel JAHA were not publicly accessible. PO Resp. 11–18. The argument that Voswinckel JESC was publicly presented is not a change in theory from the Petition, because Petitioner presented this argument in the Petition. Pet. 22. As to both Voswinckel JESC and Voswinckel JAHA, Petitioner’s Reply evidence showing citation to the references in other publicly accessible documents is merely additional evidence supporting Petitioner’s original theory that a person of ordinary skill in the art could have located the references. Accordingly, we find that the following arguments made by Petitioner are not untimely: (1) that Voswinckel JESC was presented publicly, (2) that Voswinckel JESC was referenced in a publicly accessible document, and (3) that Voswinckel JAHA was referenced in a publicly accessible document.” slip op. at 10
- Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner
“Voswinckel JESC and Voswinckel JAHA were publicly accessible. “[T]he presence of a ‘research aid’ can . . . establish public accessibility” of a reference if that research aid “provide[s] a skilled artisan with a sufficiently definite roadmap leading to” the reference by “provid[ing] enough details [to] determine that an interested party is reasonably certain to arrive at the destination: the potentially invalidating reference.” Blue Calypso, LLC v. Groupon, Inc., 815 F.3d 1331, 1350 (Fed. Cir. 2016). Here, Petitioner directs us to research aids for finding both Voswinckel JESC and Voswinckel JAHA: a “June 2005 Ghofrani article in the journal Herz” for the former, and “a March 2005 article authored by Roxana Sulica et al. in the Expert Review of Cardiovascular Therapy” for the latter. Reply 3, 7 (citing Ex. 1010, 298, 301; Ex. 1104, 359). The Ghofrani article cites Voswinckel JESC as providing a solution to patients experiencing “pain at the injection site” by replacing injected treprostinil for “pulmonary arterial hypertension” with “inhaled treprostinil.” Ex. 1010, 298 (citing reference 6), 301 (defining reference 6 as Voswinckel JESC). The Ghofrani article also discusses the study reported in Voswinckel JESC, summarizing both the “major reduction in pulmonary selective pressure and resistance” and the lack of “adverse effects” described in Voswinckel JESC. Id. The Sulica article cites to Voswinckel JAHA, explaining that the reference reports that “inhaled treprostinil demonstrated substantial pulmonary vasodilatory efficacy in acute administration, as well as symptomatic and functional benefit in chronic use in a small number of PAH patients.” Ex. 1104, 351, 359. Thus, both the Ghofrani article and the Sulica article provide roadmaps directing a person of ordinary skill in the art looking for successful studies discussing the use of inhaled treprostinil in pulmonary arterial hypertension straight to Voswinckel JESC or Voswinckel JAHA. Because these articles provide these roadmaps, they are “research aid[s]” that “establish [the] public accessibility” of Voswinckel JESC and Voswinckel JAHA.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“The preponderance of the evidence supports Petitioner’s position. Patent Owner is correct that Voswinckel JESC notes that side effects could occur more frequently at higher doses than at lower doses. Ex. 1007, 7. But there is considerable evidence of record that a person of ordinary skill in the art would not have avoided increasing Voswinckel JESC’s dose due to the side effects reported in Voswinckel JESC. First, Dr. Hill testifies that “[p]otential side effects are always weighed against potential clinical benefit, and pulmonary arterial hypertension is a serious, life-threatening disease where physicians and patients are more willing to tolerate side effects . . . to obtain clinical benefit.” Ex. 1106 ¶ 74. Second, Dr. Waxman testifies that “[u]sually the headache goes away” and “there are things that can be done to help ameliorate the cough so in general we are able to get over that issue.” Ex. 1108, 101:19–102:10. Together with Voswinckel JESC’s description of potential side effects as “mild and transient,” this evidence supports a finding that a person of ordinary skill in the art would not have been deterred from pursuing the course that is supported by the evidence to which Petitioner directs us. With respect to reasonable expectation of success, Petitioner argues that a person of ordinary skill in the art would have had a reasonable expectation of success in combining the teachings of the ’212 patent, Voswinckel JESC, and Voswinckel JAHA because Voswinckel JAHA teaches that “[t]olerability is excellent” for its short-duration, high-concentration treprostinil inhalation therapy. Pet. 33 (citing Ex. 1008, 3). Other than the argument discussed above about side effects reported in Voswinckel JESC, Patent Owner does not raise any timely counter to this argument.8 PO Resp. 10–40. The record supports Petitioner’s argument. Ex. 1008, 3. Accordingly, Petitioner has shown by a preponderance of the evidence that a person of ordinary skill in the art would have had a reason to combine the teachings of the ’212 patent, Voswinckel JESC, and Voswinckel JAHA and that they reasonably would have expected to succeed in doing so.” slip op. at 20
- Obviousness (§103) › Objective indicia / secondary considerations › Unexpected resultsDecided for petitioner
“[U]nexpected results must establish . . . a difference between the results obtained and those of the closest prior art.” Bristol-Myers Squibb v. Teva Pharms. USA, 752 F.3d 967, 977 (Fed. Cir. 2014). Petitioner argues that the prior art over which Patent Owner argues the challenged claims showed unexpected results is not the closest prior art. Reply 24. We agree. As noted above, Patent Owner argues that the challenged claims show unexpected results over inhaled iloprost, intravenous epoprostenol, and intravenous treprostinil. PO Resp. 55–57. But the challenged claims recite inhaled treprostinil, and, as discussed above, inhaled treprostinil is taught by each of the ’212 patent, Voswinckel JESC, and Voswinckel JAHA. Ex. 1001, 18:22–44; Ex. 1006, code (57); Ex. 1007, 7; Ex. 1008, 3; Ex. 1035, 582.
