The Board instituted IPR on claims 1–6 and all asserted grounds, finding a compelling and reasonably likely obviousness challenge to claim 1 over Kobayashi and Hshieh.

“Petitioner asserts that a person of ordinary skill in the art (“POSITA”), “at the filing date of the ’409 [p]atent[,] would have a master’s degree in electrical engineering, and at least two years of relevant work experience in the field of integrated circuit design and manufacturing.” Pet. 13 (citing Ex. 1003 ¶ 52). Patent Owner does not dispute Petitioner’s proffered level of ordinary skill in the art. See generally Prelim. Resp. 6 Hshieh et al., US 5,763,914, issued June 9, 1998. Ex. 1006 (“Hshieh”). We adopt Petitioner’s proffered level of ordinary skill in the art, which is supported by declaration testimony and consistent with the ’409 patent and prior art of record.

“Based on the preliminary arguments and evidence, we disagree with Petitioner’s proposed construction requiring the corners to be rounded via a particular process because it improperly imports a process of manufacture from the Specification into apparatus claims. See Cont’l Circuits LLC v. Intel Corp., 915 F.3d 788, 799 (Fed. Cir. 2019) (citing Vanguard Prods. Corp. v. Parker Hannifin Corp., 234 F.3d 1370, 1372–73 (Fed. Cir. 2000) (“Generally, ‘[a] novel product that meets the criteria of patentability is not limited to the process by which it was made.’”)). We also preliminarily disagree with Petitioner’s assessment of the prosecution history, i.e., that the claims were amended to distinguish the claimed rounded corners from 7 Pfirsch et al., US 6,541,818, issued April 1, 2003. Ex. 1011. Pfirsch’s rounded corners. Indeed, both the Examiner found and Patent Owner admitted that Pfirsch has the recited “rounded corner[s].” See Ex. 1002, 237, 302. Patent Owner appears, at this stage, to be correct that the claims were amended to include a “circular” contact to distinguish over Pfirsch’s square contact. See id. at 295, 302.” slip op. at 10

“We disagree at this stage. Petitioner’s rationale for combining Kobayashi with Hshieh is not solely based on Hshieh’s top view rounding being well known. Rather, Petitioner’s rationale is clearly based on express teachings in Hshieh about the benefits of top view rounding. See Pet. 54, 59 (citing Ex. 1006, 5:3–17, Figs. 6A–8B; Ex. 1003 ¶ 137); Ex. 1003 ¶¶ 122, 133. For example, Petitioner and its declarant refer to Hshieh’s teaching at column 5, lines 3–17, which states, “[i]n order to prevent the corner vulnerability where punch through weak points may be formed at the sharp corners due to a three-dimension diffusion effect . . . , the sharp corners of the polysilicon openings can be either blunted or rounded.” See Pet. 59; see Ex. 1003 ¶ 137. Accordingly, at this stage, we find that Petitioner has sufficiently articulated a motivation to combine the top view rounding of Hshieh with Kobayashi.” slip op. at 24

“Next, Patent Owner argues that Hshieh teaches non-orthogonal parallelogram-shaped cells to increase cell packing density and “specifically identifies square cell configurations as having disadvantageous packing densities.” Prelim. Resp. 23. Patent Owner argues that Hshieh therefore “plainly teach[es] away from combining Hshieh with Kobayashi in the manner claimed.” Id. We do not agree at this stage. Although Hshieh teaches that non- orthogonal cells are preferable over square cells, Patent Owner has not pointed out anything in Hshieh that would “criticize, discredit, or otherwise discourage” modifying Kobayashi’s square cells to have rounded corners. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004); see also DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed. Cir. 2009) (“A reference does not teach away . . . if it merely expresses a general preference for an alternative invention . . . .”). Thus, we find nothing in the preliminary record to suggest that Hshieh teaches away from the combination.” slip op. at 25

“Based on the information above, we conclude that the limitation “a groove that is laterally offset from the chamfered mandrel” requires the groove to be entirely to the side of any part of the mandrel. This construction is consistent with the words of the claim—the claim states that the groove is laterally offset from, or to the side of, the chamfered mandrel, not merely offset from a portion of or the centerline of the mandrel. This construction is also consistent with the one embodiment describing the relationship between the mandrel and groove containing the seal, which depicts the groove entirely to the side of the chamfered mandrel. We do not accept Mr. Jobin’s testimony that laterally offset is determined relative to the centerline of an object. Neither the intrinsic record nor other extrinsic evidence provides support for Mr. Jobin identifying the centerline of an object as the reference point for determining if a point is laterally offset from the object.” slip op. at 31

“We do not agree with Petitioner that Yoakim teaches a groove that is laterally offset from the chamfered mandrel. As we indicated in our claim construction section, we construe the claim term to require the groove to be entirely to the side of any part of the mandrel. We agree with Patent Owner that, as depicted in Yoakim’s Figure 35, the alleged groove is not entirely to the side of any part of the mandrel. See Pet. 69; see also Pet. Reply 19 (showing the alleged groove, in red, including a portion over the chamfered mandrel); PO Resp. 55 (same). Even if Petitioner’s position is that all of the groove must be to the side of the centerline of the mandrel, Petitioner fails to prove that Yoakim teaches such a structure.

“Patent Owner disagrees, arguing that Petitioner’s proposed definition “completely ignores having any experience” within the field of “an insertion tube suitable for the renovation of subterranean pipes.” Prelim.

In Patent Owner’s view, the ordinarily skilled artisan would have had “some knowledge and experience in the end-use performance of polymeric films and sheet products” and, moreover, “would not necessarily have experience in the formulation or manufacturing of” those films and products. Id. On that basis, Patent Owner proposes modifying Petitioner’s definition by deleting “experience in the formulation or manufacturing of polymeric films and sheet products.” Id. The prior art itself can reflect the appropriate level of ordinary skill in the art. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Each asserted reference in this case refers to manufacturing or formulating processes for polymeric materials useful in subterranean pipe renovation, which supports Petitioner’s proposed definition.

“that appear in claim 1.

See id. at 30 (citing Ex. 1003 ¶ 134) (Petitioner’s reliance on extrinsic evidence to show that waxes migrate to the surface of the inner tubular film and, thereby, create “a ‘coating’” on that structure).

Petitioner proposes two grounds that do not depend on a finding that a migrating compound incorporated into a film is “a coating or covering” as specified in claim 1, but instead are based on prior art that allegedly teaches a migrating compound applied over a film to satisfy the second, alternative prong of Petitioner’s proposed definition.

“For the above reasons, we determine that the challenged claims are not entitled to the benefit of the filing date of the ’176 application because the application does not indicate that the inventors had possession of the hardness limitation of the claimed invention.

On the full trial record, we find that the earliest effective filing date to which the challenged claims are entitled is December 18, 2019, the filing date of the ’256 application from which the ’263 patent issued.

Conflicting Opinion Testimony Petitioner’s own witness, Dr. Giacomin, opines that an ordinarily skilled artisan “would have been familiar with various machines and methods that would have enabled the thermoforming of multilayer dental sheets into shapes that conform with the teeth (i.e., creating a dental appliance).” Ex. 1002 ¶ 25. Nonetheless, Petitioner does not contest Patent Owner’s evidence that Dr. Giacomin himself lacks that qualification. Compare Resp. 9–10 (citing Ex. 1002 ¶¶ 1–9, 17 & n.1), with Reply (nowhere contesting that evidence). Petitioner also leaves uncontested Patent Owner’s evidence that Dr. Osswald, by contrast, possesses “the required experience” with dental appliances, including thermoforming processes for their manufacture. Compare Resp. 10 (citing Ex. 2006 ¶¶ 2–8; Ex. 2007), with Reply (nowhere contesting that evidence). Dr. Giacomin possesses excellent qualifications in the field of polymer rheology, but on this record, he demonstrates no, or inadequate, familiarity or experience with methods of thermoforming dental appliances from polymeric materials, which by his own admission is a minimum qualification of the hypothetical person of ordinary skill in the art. Ex. 1002 ¶¶ 1–11 (statement of qualifications), App’x A (curriculum vitae). Patent Owner’s witness, Dr. Osswald, by contrast, has “experience with polymer materials used in dental appliances” and “shaping operations, including thermoforming” processes for such applications. Ex. 2006 ¶¶ 5, 6. Against that backdrop, where the two witnesses’ opinions differ about the level of ordinarily skill in the art of thermoforming processes for dental appliances at the time of the invention, we credit Dr. Osswald’s opinions over those of Dr. Giacomin. We take note, moreover, that Dr. Osswald’s opinions would not change under Petitioner’s somewhat different definition of the level of ordinary skill in the art. Ex. 2006 ¶ 14.” slip op. at 11

“In the absence of explanation by Petitioner, we are left to wonder why either of those two ranges reported in Sun would have been recognized as applicable, without modification, to the three-layer dental splint of Hinz. Starting with a commercially-available, two-layer sheet of hard-soft PC-TPU or hard-soft PETG-TPU thermoplastic polymers, Hinz bonds a third layer, consisting of hard PC or hard PETG, to the soft TPU layer of the two-layer material by a process of thermoforming. No prior art reference explains how that process would have been understood to affect the overall flexural modulus of the resulting three-layer, hard-soft-hard composition. Petitioner does not supply an adequate reason for combining Sun’s preferred flexural modulus range, reported for Sun’s dental appliances at a temperature of 23˚ C, to dental splints formed by Hinz from fundamentally different polymers and a fundamentally different process. See Pet. 65–68 (entirety of four-page analysis on this ground); Resp. 32–38; Sur-reply 7–14 (well-supported explanation of those fundamental differences); Reply 8–16 (Petitioner’s unpersuasive responsive positions). The flexural modulus of Sun’s dental appliance not only is temperature dependent but also varies with the flexural strength of the polymeric material at hand. Ex. 1018 ¶ 12. Too late in the Reply, Petitioner raises fact-intensive reasons why those differences would not have mattered to an ordinarily skilled artisan. Reply 8–16. In any event, we agree with Patent Owner that Petitioner glosses over “[f]undamental differences” between the polymers and processes of Sun and Hinz, differences that “are central to [the] motivation to combine inquiry” and undercut Petitioner’s view that an ordinarily skilled artisan would have understood either of Sun’s flexural modulus ranges to apply, without modification, to Hinz’s polymers and process. Resp. 33 (quoting Adidas AG v. Nike, Inc., 963 F.3d 1355, 1359 (Fed. Cir. 2020)) (first alteration in original); see Sur-reply 8–16 (Patent Owner’s persuasive arguments and evidence on point).

“On this record, we determine that Petitioner advances Dr. Medlin’s testimony to make out a claim limitation that is not suggested, much less taught, by the text of the prior art reference at hand. Because that testimony lacks objective support or adequate technical reasoning, it is entitled “little weight” and, moreover, is insufficient to support institution of trial. Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (Aug. 24, 2022) (precedential). Dr. Medlin’s remaining testimony relies on the testimony we have discussed so far. Ex. 1004 ¶¶ 201–204, 207–210, 224–226. Accordingly, this testimony does not show sufficiently that Tomosada would have suggested to a person of ordinary skill in the art that anodes should be placed within 10 inches of Tomosada’s hot liquid inlet. Because Petitioner relies on Dr. Medlin’s testimony to show that a person of ordinary skill in the art would have understood that Tomosada suggested placing an anode within 10 inches of a hot liquid inlet to a radiator, and because that testimony does not show sufficiently that a person of ordinary skill in the art would have had such an understanding, we determine that Petitioner has not shown a reasonable likelihood of prevailing with respect to any claim challenged on the basis of Tomosada.” slip op. at 13

Apotex, Inc., 655 F.3d 1352, 1360 (Fed. Cir. 2011). “Rather, obviousness requires the additional showing that a person of ordinary skill at the time of the invention would have selected and combined those prior art elements in the normal course of research and development to yield the claimed invention.” Id. (citing KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 421 (2007)). “This is so because inventions in most, if not all, instances rely upon building blocks long since uncovered, and claimed discoveries almost of necessity will be combinations of what, in some sense, is already known.” KSR, 550 U.S. at 418–19. On the other hand, an obviousness analysis “need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.” Id. at 418; accord In re Translogic Tech., Inc., 504 F.3d 1249, 1259 (Fed.

“B. Level of Ordinary Skill in the Art Petitioner asserts that a person of ordinary skill in the art “would have had at least a bachelor’s degree in mechanical engineering, metallurgical engineering, or materials science engineering, and have two or more years of experience in mechanical engineering, metallurgical engineering, or materials science engineering and/or corrosion prevention system design.” Pet. 16 (citing Ex. 1004 ¶¶ 72–75). According to Petitioner, “[a] person could also have qualified as a [person of ordinary skill in the art] with some combination of more formal education (e.g., a Ph.D.) and less technical experience,” or vice versa. Id. at 16–17. “To the extent necessary, the [person of ordinary skill in the art] may have collaborated with other skilled artisans, such that the individual and/or team collectively would have had experience and/or knowledge or particular characteristics of a radiator system.” Id. at 17. “For the limited purpose of [its] Preliminary Response, Patent Owner does not contest Petitioner’s definition of a person of ordinary skill in the art, but it reserves the right to do so if trial is instituted.” Prelim. Resp. 7. In light of the record before us, and for purposes of this Decision, we adopt Petitioner’s proposal regarding the level of ordinary skill in the art. Based on our review of the ’494 patent and the prior art of record, we determine that the definition offered by Petitioner comports with the qualifications a person would have needed to understand and implement the teachings of the ’494 patent and the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Under Phillips, claim terms are afforded “their ordinary and customary meaning.” Phillips, 415 F.3d at 1312. “[T]he ordinary and customary meaning of a claim term is the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” Id. at 1313. “Importantly, the person of ordinary skill in the art is deemed to read the claim term not only in the context of the particular claim in which the disputed term appears, but in the context of the entire patent, including the specification.” Id. Both parties argue that we need not construe any terms in order to decide whether to institute trial. Pet. 17; Prelim. Resp. 8. We agree. After considering the arguments and information presented in the Petition and Preliminary Response, we determine that we do not need to construe any terms expressly for purposes of this Decision.

“considered” is an IDS statement. Ex. 2003; cited at Prelim Resp. 23. The IDS statement contains two sets of documents. Ex. 2003, 1–12 (first set); 15–22 (second set). The first set lists over 250 references, one of which includes Brown. Id. at 6, reference 4E. The Examiner signed the bottom of the page citing Brown on Sept. 24, 2015. Where the Examiner signed the page, it states that the Examiner “CONSIDERED” on that date (i.e., on Sept. 24, 2015). What precisely the Examiner “considered” on that date is unclear because none of the citations, including to Brown, have been initialed.

“declaration addresses the Patent Owner Response and is relevant to the issues at hand. We start with an important observation: claim 18 (the only independent claim at issue) is an apparatus claim; the claim is directed to a “semiconductor light source.” Ex. 1001, 9:52, EPRC 1:32. One requirement of this apparatus is that it comprise “a semiconductor chip” (id. at 9:66) where “said semiconductor chip is a light emitting diode (LED) chip EPRC, 1:34–36. As we explain when addressing claim construction, infra, we adopt Patent Owner’s proposed construction (Resp. 14) of “said semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as referring to “a semiconductor LED chip 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 LED 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. 53 (quoting Ex. 1008, 10). Notably, claim 18 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 9

“We agree with Patent Owner that the challenged claims relate to light fixtures, LED packaging, and LED chip layer structure and that the ’770 patent claims reflect “a hybrid of the light bulb art and semiconductor art.” Resp. 16. 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 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 ’770 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.

“Delaware held, with respect to related U.S. Patent 6,465,961, construed “a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as “at least one LED chip is capable of emitting light greater than about 40 milliwatts.” Resp. 14 (citing Ex. 1024, 15–18). Petitioner responds that the phrase “needs no construction” and that Petitioner’s grounds meet this construction. Reply 1. We note that the language of claim 18 does not precisely match the language the District Court considered, it is substantively the same. The record supports a construction very similar to the construction the District Court adopts, and we reference the District Court’s reasoning. Ex. 1024, 15– 18. We, thus, construe claim 18’s recitation that “said semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as referring to “a semiconductor LED chip that is capable of emitting light greater than about 40 milliwatts.” It is unnecessary to construe any other claim terms in this Decision because none of the parties’ disputes turn on the meaning of other terms.

- Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedReference is prior artDecided for petitioner
“The facts above are evidence of the Krames reference’s publication as of June 29, 2000, because the facts tend to make the Krames reference’s publication as of June 29, 2000, more probable than it would be without the evidence. See Fed. R. Evid. 401(a) (defining evidence as relevant “if it has any tendency to make a fact more or less probable than it would be without the evidence”). The evidence is sufficient to support publication. Meanwhile, no evidence of record suggests that Krames was not a printed publication as of June 29, 2000. Thus, a preponderance of the evidence supports Krames’s prior art status. Patent Owner argues that Ms. Watters “never establishes a firm date when Krames was purportedly available to the relevant public.” Resp. 21. Patent Owner bases this argument by taking a tortured reading of Ms. Watters’s statement that “[m]embers of the interested public could locate a copy of [the Proceedings] on or after June 29, 2000, the date it was catalogued.” Id. (quoting Ex. 1020, 3); see also Sur-Reply 12–13. The best understanding of Ms. Watters’s statement, in view of the context of Ms. Watters explaining the library’s cataloguing process, is that a member of the interested public had two options: the person could choose to locate the Proceedings on June 29, 2000, or the person could choose to locate the Proceedings after June 29, 2000. Thus, the statement supports public availability as of June 29, 2000.” slip op. at 21
