“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

“Inc., 868 F.2d 1251, 1257 (Fed.

(quoting Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305 (Fed. Cir. 1999)). “Conversely, a preamble is not limiting ‘where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.’” Id. (quoting Rowe v. Dror, 112 F.3d 473, 478 (Fed. Cir. 1997)). The court in Catalina noted that although no litmus test exists for determining whether to treat a preamble as a limitation, several “guideposts” have emerged from the case law in this area. Id. In particular, guideposts tending to show that the preamble is a claim limitation include: Jepson claiming, dependence on a particular disputed preamble phrase for antecedent basis, when the preamble is essential to understand limitations or terms in the claim body, and when the preamble recites additional structure or steps underscored as important by the specification. Id. On the other hand, the preamble might not constitute a claim limitation when the claim body describes such a structurally complete invention that deleting the preamble phrase does not affect the structure or steps of the claimed invention.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner
“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

“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. Blue Calypso, 815 F.3d at 1350.” slip op. at 11
- 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. Patent Owner does not even allege that the results of the challenged claims are unexpected over these references.9 Accordingly, we find that the evidence of record does not establish that the challenged claims produced a result that was unexpected over the closest prior art. slip op. at 22

Under that standard, absent any special definitions, we assign claim terms their ordinary and customary meaning, as understood by a person of ordinary skill in the art, in the context of the entire patent disclosure. In re Translogic Tech., Inc., 504 F.3d 1249, 1257 (Fed. Cir. 2007). Only terms which are in controversy need to be construed, and then only to the extent necessary to resolve the controversy.

“Where the prior art teaches the claimed invention, a claim is not rendered patentable by virtue of being motivated in the inventors’ minds by a newly-discovered advantage of the prior-art combination; allowing such a claim to stand “would remove from the public that which is in the public domain.” In re Wiseman, 596 F.2d 1019, 1022 (CCPA 1979); see also Cross Med. Prods., Inc. v. Medtronic Sofamor Danek, Inc., 424 F.3d 1293, 1323 (Fed. Cir. 2005) (“One of ordinary skill in the art need not see the identical problem addressed in a prior art reference to be motivated to apply its teachings.”). Here, Patent Owners argue that the newly discovered low-dose instability of fingolimod when mixed with common excipients motivated the inventors’ choice of the allegedly less common mannitol as an excipient. PO Resp. 12–15 (citing Ex. 2043 ¶¶ 14–19, 22, 24–36). As explained above, though, it does not matter that the prior art failed to recognize this advantage of a fingolimod-mannitol combination. “[T]he motivation in the prior art to combine the references does not have to be identical to that of the [patentee] to establish obviousness.” In re Kemps, 97 F.3d 1427, 1430 (Fed.

“Kitamura is largely silent as to the specific functioning of the D/A conversion circuit 10. Kitamura discloses that D/A conversion circuit 10 and A/D conversion circuit 13 “preferably share a voltage dividing element and a reference voltage supply (for the purpose of making their characteristics uniform),” and level differences to maximize the operating margin (Ex. 1010 ¶ 11), but does not disclose a “selection” between reference voltages or signals. Although Petitioners emphasize the obviousness of certain elements of the challenged claims (Pet. 25– 26), the obviousness of selecting a reference voltage versus outputting a voltage from a D/A conversion is not discussed. Indeed, Dr. Baker’s discussion is clear (Ex. 1003 ¶¶ 74–79) as to how the output voltages could be set, but it remains unclear how Kitamura itself suggests the examples proffered. The normal function of a D/A converter is not to select between reference voltages, but to render the digital input into analog form. We are not persuaded that Kitamura teaches or suggests the selection of one of a plurality of reference voltages in accordance with the input information, per the challenged claims. In addition, the Petitions fail to provide any rationale for why Kitamura’s disclosure of D/A conversion renders the selection of a reference voltage or signal obvious. For these reasons, Patent Owner’s contentions that Kitamura does not teach or suggest “reference voltage selecting means,” or equivalent elements, or “reference voltages,” per the challenged claims, are persuasive.

“[a] playlist is a list of a user’s favorite selections.” Ex. 1001, 1:33–34. Patent Owner quotes from the specification of the ’099 Patent: Playlists also facilitate the playing of a plurality of selections in a particular order. That is, the playlist may be compiled in an order in which the playing of selections therefrom is desired. The selections may then be automatically played sequentially from the playlist. Typically, selections may also be played randomly from a playlist. PO Resp. 10; Ex. 1001, 1:45–52 (emphasis added).2 As noted by Petitioner, this passage reflects that a playlist may have a particular order of selections (see Pet. Reply 6), but also expressly discloses that selections may be played randomly from a playlist. slip op. at 8

Petitioner argues that Patent Owner’s proposal is narrow and excludes “a standard remote control for a device,” Pet. Reply 8–9. We agree, as in addition to the Petitioner’s contentions, we note the terms “operate” and “independent” do not appear in the ’099 patent. 9 We decline to adopt Patent Owner’s proposed construction over the ordinary and customary meaning of the term.” slip op. at 9
- Skill levelOther
“year of practical experience with networked multimedia.” Ex. 1002 ¶ 8. Patent Owner’s proposal is similar, requiring “a person with a bachelor’s degree in computer science or electrical engineering and one year of practical experience with networked media.” PO Resp. 7. The parties dispute Petitioner’s use of the qualifying phrase “at least” in describing the level of education and work experience. While we disagree with Patent Owner’s argument that “at least” is “improper because it is open-ended” (PO Resp. 7–8),3 we determine that an express definition of the level of ordinary skill is not required. The level of ordinary skill in the art can be reflected in the cited prior art references. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“the absence of specific findings on the level of skill in the art does not give rise to reversible error where the prior art itself reflects an appropriate level and a need for testimony is not shown.”) (internal quotations omitted); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995). Here, neither party has provided a sufficient explanation as to how their specific proposal regarding the level of ordinary skill (and in particular the importance of the inclusion or exclusion of “at least”) affects the analysis in this case.
