“G. Analysis 1. REAL PARTY IN INTEREST Based on the record before us and for the reasons explained below, we disagree with Patent Owner that Menard is a “real party in interest” under § 315(b). See Resp. 77–82; Sur-reply 27–28. First, the circumstances here differ materially from the circumstances in Ventex. There, two agreements defined the relationship between Ventex (the petitioner and manufacturer of Heatwave fabric) and Seirus (the alleged real party in interest and purchaser of Heatwave fabric). Ventex, IPR2017- 00651, Paper 152 at 7 & n.8. First, a 2013 Supplier Agreement “prevented Ventex from selling to Seirus competitors” and included an indemnity provision requiring Ventex to indemnify Seirus for losses arising from Ventex’s failure to perform certain obligations. Id. at 7, 14. Second, a 2016 Exclusive Manufacturing Agreement provided that Ventex would manufacture the Heatwave fabric only for Seirus in exchange for Seirus’s payment of an exclusivity fee. Id. at 7. Columbia (the patent owner) accused Seirus products incorporating the Heatwave fabric of infringing the patent at issue, and Columbia served Seirus with a complaint alleging patent infringement in 2014 more than two years before Ventex filed a petition in 2017. Id. at 5, 7. When determining that Seirus was a “real party in interest” under § 315(b), the Board reasoned that “Ventex and Seirus had a specially structured, preexisting, and well established business relationship with one another, including indemnification and exclusivity arrangements.” Ventex, IPR2017-00651, Paper 152 at 10; see id. at 12.

- Skill levelOther
“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

“II. TIMELINESS OF THE PETITION UNDER 35 U.S.C. § 315(B) Pursuant to 35 U.S.C. § 315(b), “[a]n inter partes review may not be instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” Patent Owner argues that the Petition is untimely under 35 U.S.C. § 315(b) because Petitioner is in privity with time-barred entities. Prelim. Resp. 10– 30. However, 35 U.S.C. § 315(b) also provides that the one-year time bar “shall not apply to a request for joinder under subsection (c).” See also 37 C.F.R. § 42.122(b). Because the Petition is accompanied by a timely request for joinder (Paper 2) to the instituted proceeding (IPR2024-00017), which we grant as further discussed below, Patent Owner’s argument that the Petition is time-barred under 35 U.S.C. § 315(b) is moot, irrespective of whether Petitioner is in privity with time-barred entities.” slip op. at 5

A motion for joinder should (1) set forth reasons why joinder is appropriate; (2) identify any new grounds of unpatentability asserted in the petition; (3) explain what impact (if any) joinder would have on the trial schedule for the existing review; and (4) address specifically how briefing and discovery may be simplified.

As the moving party, Petitioner bears the burden of proving that it is entitled to the requested relief. 37 C.F.R. § 42.20(c). As an initial matter, we find the Motion for Joinder meets the timing requirements of 37 C.F.R. § 42.122(b) because Petitioner filed it on April 4, 2024, no later than one month after the Cirrus IPR was instituted on May 1, 2024.” slip op. at 9

“5. “Aid the Movement of Minority Carriers” Patent Owner argues that the Petition fails to show that the applied prior art references disclose the claim limitations “requiring ‘aid the movement of minority carriers,’” as twice recited in claim 1. Prelim. Resp. 8. Patent Owner summarizes this dispute as follows: The challenged patent discloses and claims a semiconductor device with (among other things) a “drift layer having a graded concentration of dopants . . . [and] further having a first static unidirectional electric drift field to aid the movement of minority carriers.”[] The Petition should not be instituted, because (among other deficiencies) it fails to show that the prior art discloses the “aid the movement of minority carriers” claim limitation. Rather than pointing to anything in the prior art that would teach this claim limitation, the Petition assumes that any “graded concentration of dopants” would necessarily “aid the movement of minority carriers.” The Petition contains no analysis explaining why the “graded concentration of dopants” in the prior art meet the “aid the movement of minority carriers” limitation, apart from the fact that they are “graded concentration of dopants.” In other words, Petitioner reads the “aid the movement of minority carriers” limitation out of the claims completely.

“Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed.

Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan.

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.

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

“The definiteness requirement of § 112(a) is satisfied when “a patent’s claims, viewed in light of the specification and prosecution history, inform those skilled in the art about the scope of the invention with reasonable clarity.” Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898, 910 (2014); see 37 C.F.R. § 42.100(b) (changing the claim construction standard used to review a claim proposed in a motion to amend from the broadest reasonable construction to the “same construction standard that would be used to construe the claim in a civil action under 35 U.S.C. [§] 282(b)”). Proposed substitute claim 104 generically requires “in situ precipitate” and also a specific type of in situ precipitate: “in situ galvanically-active intermetallic precipitate.” Mot. Appendix A. 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.

“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

“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.

“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

“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

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.

“suggested formula” assigned to them is “based on a calculation that relied on the average of a wide distribution of particle sizes reported in the literature by Hutchison.” Ex. 2030 ¶ 103(citing Ex. 2017, 12891). We assign persuasive weight to her testimony because it is based upon the disclosures in Hutchison, which Banin explicitly identifies as the published procedures by which it synthesized its clusters. In particular, Dr. Cossairt’s testimony is supported by the following discussion in Hutchison: To calculate an average molecular formula for 1 it is necessary to know the number of gold atoms in the metal core. Given the average particle size (1.5 nm) this number is estimated to be ~101 by the method of Whetten et al. and leads to an estimated formula of Au101(PPh3)21Cl5. Ex. 2017, 12891. In other words, Hutchison explains that it calculated an average molecular formula for its synthesized nanoparticles by estimating the number of gold atoms in the metal core based upon the average particle size of 1.5 nm. Id. Indeed, as Dr. Cossairt has recognized, Banin’s “suggested formula” is exactly the same molecular formula that Hutchison discloses as the “average molecular formula” for its nanoparticles. Thus, we determine that the record as a whole supports finding that a person of ordinary skill in the art would have understood that Banin’s “suggested formula” represents an average molecular formula for a disperse mixture of gold clusters that are not identical and do not have sufficiently well-defined chemical structure such that all molecules of the cluster compound possess the same relative molecular formula, as required for MCCs. slip op. at 23

“Specification expressly defines the term “molecular cluster” in a manner that refers to the cluster compound. According to the Specification, “Molecular cluster” is a term which is widely understood in the relevant technical field but for the sake of clarity should be understood herein to relate to clusters of 3 or more metal or nonmetal atoms and their associated ligands of sufficiently well defined chemical structure such that all molecules of the cluster compound possess the same relative molecular mass. Ex. 1001, 5:3–9. We note that the District Court determined that “the term ‘molecular formula’ as opposed to ‘molecular mass’ is most appropriate. By necessity, a compound with the same molecular formula will necessarily have the same molecular mass.” Ex. 1091, 16. The District Court explained also, “it appears that the difference between a molecular formula and a molecular mass, at least for purposes of this claim construction, in inconsequential.” Id. We agree and do not find any dispute on the current record from the parties on this matter.

“that Petitioner has not shown persuasively that a person of ordinary skill in the art would have considered Banin’s small Au clusters to be MCCs.

Instead, they refer to Banin’s disclosure that the Au clusters have “the suggested formula Au101(PPh3)21Cl5” and are “1.4 nm in mean diameter.” In doing so, Petitioner and Dr. Green do not meaningfully address or adequately explain how Banin derived its “suggested” molecular formula for the gold clusters or why Banin reported a “mean” diameter for those clusters.
