    “In order to determine whether an invention would have been obvious at the time the application was filed, we consider the level of ordinary skill in the pertinent art. Graham, 383 U.S. at 17. In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (quotation omitted). Petitioner contends a person of ordinary skill in the art “would have possessed at least a four-year degree in electrical engineering, chemical engineering, physics, or material science, or a closely related field, and at least two years of experience in semiconductor device design or fabrication, including the processing of semiconductor materials, analysis of device operation, or the development of new device topologies.” Pet. 5–6. Petitioner contends “[a]dditional education could substitute for professional experience and vice versa.” Id. at 6. Patent Owner contends that a person of ordinary skill in the art would have had “at least a four-year degree in electrical engineering, physics, material science, or a closely related field, and three years of professional work experience in the epitaxial growth, design, and fabrication of semiconductor electronic devices, including those of GaN.” PO Resp. 7 (citing Ex. 2009 ¶ 82). Upon review of the evidence of record and the parties’ arguments, we adopt Petitioner’s definition of the person of ordinary skill in the art as it is consistent with the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (holding that the prior art itself can reflect the appropriate level of ordinary skill in the art). We note, however, that the conclusions reached in this Decision would be the same under either proposed definition of the ordinarily skilled artisan. See Ex. 2009 ¶ 83 (Dr. Schubert testifying that his opinions would be the same under either proposed definition); Ex. 1033 ¶ 9 (Dr. Shealy testifying that the differences in proposed definitions of the ordinarily skilled artisan “would not change the outcome of the invalidity analysis in any material manner”); PO Resp. 7; Pet.

    “compensated GaN layer above the barrier layer, and a gate contact above the compensated GaN layer.” Ex. 1001, 5:12–18. Petitioner contends the term “compensated” indicates that the step of compensating the GaN layer has already occurred, such that the term “compensated GaN layer” should be construed as a “‘[d]oped GaN layer formed with a step to passivate its impurities’ which is a ‘product-by-process’ limitation.”5 Pet. 12–14. And, because compensation with hydrogen was the “critical step” distinguishing the claims from the prior art, and because hydrogenation in as-grown III-nitride materials had been well known for over a decade by 2009, Petitioner contends “compensated” “cannot be interpreted as mere hydrogen presence in as-grown material, a well-known property of doped GaN.” Id. at 15. Patent Owner contends “compensated GaN material” should be construed as “a semiconductor GaN gate material in which one type of impurity (for example, donor) cancels the electrical effects of the other type of impurity (for example, acceptor).” PO Resp. 11 (citing Ex. 2009 ¶ 92) (emphasis added). Patent Owner contends this construction is consistent with the IEEE dictionary, which defines “compensated semiconductor” as 5 Given that product-by-process steps in a device claim are not entitled to patentable weight, Petitioner contends “the prior art only need show a material with passivated impurities to show unpatentability, not the step to achieve it.” Pet. 15–16. “[a] semiconductor in which one type of impurity or imperfection (for example, donor) partially cancels the electric effects of the other type of impurity or imperfection (for example, acceptor).” PO Resp. 14 (quoting Ex. 2004). Patent Owner contends its construction is also consistent with the written description of the ’294 patent, which explains that a compensated GaN material is part of the gate and includes a p-type impurity that imparts an electrical effect (i.e., conductivity), as well as a second impurity, e.g., hydrogen, that partially cancels the electrical effect of the p-type impurity, rendering the layer semi-insulating. Id. at 14–15 (citing Ex. 1001, 3:10–13, 3:43–45). On this record, we construe “compensated GaN layer” as “a GaN layer in which one type of impurity (for example, donor) partially cancels the electric effects of the other type of impurity (for example, acceptor).” This is consistent with the disclosures of the ’294 patent, the IEEE dictionary definition, and the construction ultimately adopted by the ITC. Ex. 2004, 3; Ex. 1049, 16–17 (ITC construing “compensated GaN layer” to mean “a GaN layer in which one type of impurity partially cancels the electrical effects of another type of impurity”); Ex. 1001, 3:43–45 (explaining that the compensated GaN layer of the ’294 patent is formed through the “passivation of a p-type impurity using hydrogen”). For the reasons set forth below, however, we decline to construe “compensated GaN layer” as a product-by-process claim term (as asserted by Petitioner), or to limit the compensated GaN layer to a gate material (as asserted by Patent Owner).” slip op. at 11

  • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner

    “There are two exceptions to the general rule that we apply the ordinary and customary meaning of a claim term: (1) when a patentee sets out a definition and acts as his own lexicographer, or (2) when the patentee disavows the full scope of a claim term either in the specification or during prosecution. See Thorner, 669 F.3d at 1365. The standards for lexicography and disclaimer, however, are “exacting.” Id. at 1366. There is no argument that the patentees acted as their own lexicographer to redefine the term “compensated GaN layer.” With respect to disavowal, a “patentee may demonstrate intent to deviate from the ordinary and accustomed meaning of a claim term by including in the specification expressions of manifest exclusion or restriction, representing a clear disavowal of claim scope.” Thorner, 669 F.3d at 1366 (quoting Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1325 (Fed. Cir. 2002)). As noted by Patent Owner, the title of the ’294 patent is, in part, “Compensated Gate MISFET” and much of the discussion of the ’294 patent is of a compensated GaN layer that is directly below the gate contact and above a barrier layer and operates in conjunction with the gate contact to control the on/off state of the transistor. PO Resp. 12–14. We are presented with insufficient argument or evidence to conclude, however, that these disclosures rise to the level of a disclaimer. For example, although the title of the ’294 patent is directed to a “Compensated Gate MISFET,” claim 1 is more broadly directed to “[a] column III Nitride transistor.” Ex. 1001, 5:12, code (54). Nor are we directed to an expression or statement of manifest exclusion in the ’294 patent that would serve to disclaim any “compensated GaN layer” that is not directly below the gate and/or that does not function in concert with the gate electrode to control the on/off state of the transistor. See Thorner, 669 F.3d at 1366. With respect to the stated goals of the invention, as noted by Patent Owner, one of the primary purposes of the compensated GaN layer of the ’294 patent is to reduce gate leakage and gate capacitance. Ex. 1001, 2:13– 19, 3:18–21 (“[U]sing a compensated semiconductor layer 38 leads to low gate leakage during device operation.”). We cannot use the goals of the invention, however, to rewrite the claims or insert terms that are not present. See Thorner, 669 F.3d at 1366. Moreover, the prior art of record indicates that a compensated GaN layer that is below the gate contact and above a barrier layer, but not part of the active gate structure, may also “decrease the leakage current between the gate and the drain.” Ex. 1006 ¶¶ 44 (“Even when a positive bias of 5 V or higher is applied to the gate electrode, no significant gate-leakage current is observed.”), 61. As such, evidence of record suggests that a person of ordinary skill in the art would have understood that one of the primary goals disclosed in the ’294 patent is achieved regardless of whether the compensated GaN layer is part of the gate, or simply in close vicinity to the gate. In view of the foregoing, we are not persuaded that the written description of the ’294 patent indicates that the “compensated GaN layer” must be part of the gate structure.” slip op. at 17

  • Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for petitioner

    “To be probative, Patent Owner must prove there is a nexus between the presented evidence and the merits of the claimed invention. See Demaco Corp. v. F. Von Langsdorff Licensing Ltd., 851 F.2d 1387, 1392 (Fed. Cir. 1988). A rebuttable presumption of nexus applies when the “patentee shows that the asserted evidence is tied to a specific product and that the product ‘is the invention disclosed and claimed.’” Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (quoting Demaco, 851 F.2d at 1392). “That is, presuming nexus is appropriate ‘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.’” Id. (quoting Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1072 (Fed. Cir. 2018)). If the praise is not limited to the features of the claimed invention, the patent owner may still prove nexus “by showing that the evidence of secondary considerations is the ‘direct result of the unique characteristics of the claimed invention.’” Id. at 1373–74 (quoting In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996)). Patent Owner contends that the compensated gate of the ’294 patent “was a breakthrough invention and resulted in the first commercially viable enhancement-mode GaN transistor.” PO Resp. 60 (citing Ex. 2009 ¶¶ 192– 193, 197; Ex. 2021). Patent Owner further contends that this achievement required the counter-intuitive use of a compensated gate material in the gate structure, and represented “a technological leap that laid the foundation for viable enhancement-mode GaN transistors.” Id. at 61–62. For this achievement, Patent Owner contends the inventor, Dr. Alex Lidow, received the 2015 SEMI Award. Id. at 60 (citing Ex. 2021). Upon review of Patent Owner’s evidence and the parties’ arguments, we find that Patent Owner’s objective indicia evidence is entitled to little, if any, weight. The evidence of praise relied upon by Patent Owner is not clearly linked to the claimed invention or any particular product having each of the claimed features of the ’294 patent. Ex. 2021. For example, the 2015 SEMI award was provided to Dr. Lidow “for commercialization of GaN power devices.” Id. An article explaining the award indicates that “high cost” previously “limited [the] commercial success” of GaN technologies, but Dr. Lidow was able to overcome these issues, “from resolving packaging limitations to establishing a low-cost supply chain,” “through persistence.” Id. This praise is not demonstrably linked to the claimed invention or any particular device, and does not mention the use of a compensated gate, or any other relevant feature recited in the claims. In view of the foregoing, we determine that Patent Owner’s objective evidence of non-obviousness is entitled to little, if any, weight.” slip op. at 20

    “Petitioner demonstrates by a preponderance of the evidence that a person of ordinary skill in the art would have had reasons to combine Eckhardt’s teaching of narrow spectrum UV light in the range of 220 to 310 nm to disinfect skin (Ex. 1004 ¶¶ 31, 69–70), with Sosnin’s teaching of a KrCl excimer lamp having a narrow band UV emission at 222 nm to kill bacteria (Ex. 1005, 320). In particular, Petitioner shows that a person of ordinary skill in the art would have wanted to obtain the benefits of Eckhardt’s teaching of disinfecting skin using any light source capable of sterilization or disinfection and would therefore have considered Eckhardt’s suggestion of using narrow spectrum UV light in combination with Sosnin’s disclosure of using germicidal excimer lamps within the range of wavelengths taught by Eckhardt. See KSR, 550 U.S. at 417 (stating that the “mere application of a known technique to a piece of prior art ready for the improvement” suggests obviousness). The teachings of both Eckhardt and Sosnin support Petitioner’s combination. In particular, both references teach using UV lamps with narrow bands or monochromatic emissions to sterilize surfaces. Eckhardt teaches “light source 7 may be any light source that emits light capable of sterilization or disinfection” and may be a UV light source such as a lamp that “may emit narrow spectrum light (e.g., a line spectrum) or broad spectrum light” including UVA, UVB, and UVC light. Ex. 1004 ¶ 31. Eckhardt also teaches flash light source 7a generates a flash sufficient for sterilization or disinfection and may be a xenon flash lamp having a wavelength in the range of 220 to 310 nm. Id. ¶¶ 43, 70. Additionally, Eckhardt teaches “[t]he sterilization/disinfection units previously described are designed to have a beneficial effect when used on bare skin.” Id. ¶ 69. Sosnin teaches using excimer lamps for sterilization and specifically discloses a KrCl lamp which generates photons having wavelengths of 222 nm. Ex. 1005, 320. We find that Eckhardt would have led a person of ordinary skill to consider using a 222 nm excimer lamp because that wavelength falls within the range of UV light (220–310 nm) suggested by Eckhardt, and the range known to provide disinfection. Ex. 1004 ¶ 70; Ex. 1005, 320 (describing “the high rate of bactericidal effect of excilamps”). We find that Eckhardt also supports Petitioner’s contention that it was within the knowledge of a person of ordinary skill in the art to use UV light in the range of 254 nm for disinfection, even though that wavelength presented safety concerns.

    “Although Patent Owner is correct that Petitioner does not direct us to any disclosure of a heating member having a length that “falls within the claimed range,” such a disclosure in the art is not required for a showing of obviousness. See, e.g., In re Huang, 100 F.3d 135, 136 (Fed. Cir. 1996). In Huang, the claim required a racquet grip comprising a textile layer and a polyurethane layer, and that the ratio of their thicknesses be “larger than approximately 0.18.” Id. at 137. The prior art disclosed a textile layer and polyurethane layer in thickness ratios ranging from 0.111–0.142. Id. at 136. Although the prior art did not disclose a ratio in the claimed range, the Federal Circuit affirmed the Board’s obviousness rejection because the evidence showed that “one of ordinary skill in the art would have experimented with various thicknesses to obtain an optimum range.” Id. at 139; see In re Aller, 220 F.2d 454 (CCPA 1955) (affirming an obviousness rejection of a claim to a chemical process reciting use of 25– 70% sulfuric acid at 40–80 degrees when the prior art disclosed the same reaction with 10% sulfuric acid at 100 degrees); In re Hill, 284 F.2d 955 (CCPA 1960) (affirming an obviousness rejection of a claim to a chemical process conducted at 150–250 degrees when the prior art disclosed the same reaction at 300 degrees). The Federal Circuit also noted that “Huang does not contend that he has achieved unexpected results by increasing the thickness of the polyurethane layer.” Huang, 100 F.3d at 139–140. Those principles apply with equal force to the facts in this case. Here, the evidence of record demonstrates that heaters having a length that spans some percentage of the length of the disposable aerosol forming substance were known in the art. For example, Robinson discloses one embodiment wherein heating element 72 has an elongated portion that extends into tobacco segment 89. Ex. 1006, 27:35–39, Fig. 3. Greim likewise discloses a heating element having some length, which may be inserted into a plug of an aerosol-forming substrate. Ex. 1007, 13, Fig. 4. Adams discloses similar information. Ex. 1008 ¶ 45 (“The axial length of the projection 72 is selected so that it does not extend all the way through the tobacco plug.”), Fig. 7. Following the reasoning in Huang, these disclosures of a heater having some length, albeit not necessarily a length in the claimed range, are sufficient to demonstrate obviousness if there is evidence demonstrating “one of ordinary skill in the art would have experimented with various [lengths] to obtain an optimum range” and there is no evidence that the claimed range provides unexpected results.

    “24. Pet. 20–26. Focusing on independent claim 1’s limitation “a compound selected from cysteine, cystine, thiamin, methionine, and mixtures of two or more thereof,” Petitioner asserts Brown’s disclosure of “pea flour” meets this limitation because “pea flour contains cystine, thiamine, and methionine.” Id. at 22–23 (citing Ex. 1012 (Brown) ¶ 364; Ex. 1003 (Tarte) ¶¶ 121–125; Ex. 1050/Ex. 1059 (Jahreis), 39, 41, 86; Ex. 1106, 3, 6–7). Petitioner qualifies that its mapping of “pea flour” to this claim limitation is based on the interpretation of “compound” as “not . . . limited to free compounds.” Id. at 22 n.7. Specifically, Petitioner states that the mapping is based on Brown’s “pea flour, which contains proteins having the claimed sugar and sulfur compounds.” Id. at 12; see Ex. 1003 ¶ 105 (reiterating this statement). Brown states, in pertinent part, “[a] muscle replica comprising pea flour, sunflower oil, and glucose.” Ex. 1012 ¶ 364. Dr. Tarté states in his declaration that a person of ordinary skill “would have understood that pea flour includes cystine, methionine, and thiamine.” Ex. 1003 ¶¶ 121–125. On cross-examination, Dr. Tarté stated that this mapping to the claim is based on an understanding that Brown’s proteins satisfy the sulfur compound limitation. Ex. 2032, 33:19–34:12; 98:11–99.9 (“[I]n as much as . . . Patent Owner considers proteins to satisfy the sulfur compound claim, then . . . the pea protein flour of Brown also satisfies the [sulfur] compound claim.”), 117:9–118:8. Patent Owner asserts that the Petition’s anticipation ground must fail if the claimed compound limitation does not extend to proteins. PO Resp. 13. Because we adopt the District Court’s construction of the claim term “compound,” Petitioner’s contention that Brown anticipates the ’096 patent necessarily fails. See Verdegaal Bros., 814 F.2d at 631 (“A claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.”). Petitioner concedes that the viability of this ground depends on construing the term “compound” to include whole proteins, and has failed to present evidence in this proceeding that Brown discloses a sulfur compound that is separate from a protein. Tr. 50:21–52:13 (Petitioner’s counsel conceding that the anticipation ground is not viable under the District Court’s claim construction for “compound”). Thus, Petitioner has not shown by a preponderance of the evidence that claim 1 is unpatentable as anticipated by Brown.” slip op. at 19

  • Obviousness (§103) › Analogous artNon analogous artDecided for patent owner

    “The analogous-art test requires a showing that a reference is either in the field of endeavor of the challenged patent or is reasonably pertinent to the problem with which the inventor was concerned in order to rely on that reference as a basis for unpatentability. In re Oetiker, 977 F.2d 1443, 1447 (Fed. Cir. 1992). Patent Owner argues that Petitioner fails to establish Crane as analogous art under this legal framework. PO Resp. 36–40; PO Sur-Reply 1–2. First, Patent Owner asserts Crane is not “from the same field of endeavor” as the ’096 patent. Id. at 37 (citing Ex. 2030 (Qian Decl.) ¶ 86). Based on this record, the ’096 patent is directed to food products while Crane, on the other hand, relates to “methods for producing recombinant functional heme-binding proteins.” Ex. 1001, 1:22–25; Ex. 1014, code (57). As Patent Owner points out, Crane does not even mention food products or any flavor functionality of heme-binding proteins. PO Resp. 37. Petitioner does not address Crane’s field of endeavor in its Petition or Reply. See Pet. 36–50; Pet. Reply 1 (“Petitioner . . . relies on the arguments made in the Petition for Ground 1 and 3A-3D”). We agree with Patent Owner that Crane is not from the same field of endeavor as the ’096 patent. Next, Patent Owner asserts the Petition fails to explain how Crane’s recombinant heme-binding protein is pertinent to the problem addressed by the ’096 patent inventors. According to Patent Owner, the problem solved by the inventors was “to provide meat-like-food products that overcome the limitations of prior-art meat substitutes.” PO Resp. 38. Crane, however, is directed to producing recombinant heme-binding proteins with complete heme incorporation. Ex. 1014 ¶¶ 3–5; Ex. 2030 ¶ 87. Neither Crane nor the Petition addresses how this is relevant to improving meat-associated flavors or aromas in food flavor additives. See generally, Ex. 1014; Pet. 36–50. The Petition asserts that Crane’s recombinant heme-binding protein, if used in place of Conrad’s blood/hemoglobin, which is added to improve taste, “would have produced the proteins with a high degree of purity.” Pet. 47–48. The Petition asserts that the benefit of high purity is greater control over the amount added and consistency in the end product. Id. at 48.” slip op. at 21

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

    “argument at trial, we do not agree with Patent Owner that Petitioner’s basis for improving the nutritional content of the food product of Giacino is unsupported by the record. Proulx identifies iron deficiency as “a major nutritional problem, affecting over 2 billion people[.]” Ex. 1019, 1518; Ex. 1003 ¶ 93; see also Pet. Reply 25. Based on the evidence in this record, Giacino’s compositions lack a significant source of iron. Ex. 1003 ¶¶ 387, 407. Furthermore, like Proulx, Giacino’s composition is intended to be an additive to food products. Specifically, Giacino’s composition is intended to be added to synthetic meat fibers, that may benefit from a source of iron, by mimicking not only the “meaty flavor” or aroma of meat, but the nutritional profile of conventionally sourced beef as well. Ex. 1003 ¶ 410; Ex. 1015, 7:22–26. This reasoning is supported by Petitioner’s expert, Dr. Tarté. Ex. 1003 ¶ 410. Patent Owner acknowledges the nutritive aspect of the addition is a “bonus” to the flavor impact. PO Sur-Reply 25–26. Proulx explicitly teaches adding leghemoglobin as an additive to food (“food fortificant”), therefore a POSITA would have had a reasonable expectation of success in doing so. Ex. 1019, Abs.; see id. at 1521 (“added with tortillas”). Even if the addition of Proulx’s leghemoglobin were to produce autooxidation and impact Giacino’s meaty flavor, the benefit of Proulx’s leghemoglobin as an additive to a food composition is not disputed and supports the combination. “The fact that the motivating benefit comes at the expense of another benefit, however, should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another. Instead, the benefits, both lost and gained, should be weighed against one another.” Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000). Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (“a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine”). Moreover, the evidence of record regarding the asserted negative effect on aroma and flavor due to heme proteins is that this negative impact is merely a possibility. Ex. 2030 ¶ 76 (Dr. Qian states that heme proteins have an “unpredictable effect” and refers to statements made in related patent prosecution that “fortification [with] iron has a potential negative effect on organoleptic quality of maize products, in that soluble forms of iron can cause oxidative rancidity,” quoting Ex. 1148, 2715). Based on the evidence of record, the benefit of adding heme protein taught by Proulx outweighs the potential negative effect that it may have on Giacino’s flavoring additive. Thus, the preponderance of the evidence in this record supports Petitioner’s assertion that a POSITA would have been motivated to nutritionally fortify Giacino’s meat flavoring composition by adding Proulx’s soy leghemoglobin.” slip op. at 31

    “Having considered the evidence and arguments, we determine that the preponderance of the evidence favors Petitioner. Petitioner demonstrates that a person of ordinary skill would have had a reason to modify Richardson’s jump starter with Lai’s overcharge-protection circuit. Pet. 69. In particular, Petitioner shows that in order to protect against dangerous overcharging conditions in Richardson’s jump starter, a person of ordinary skill would have replaced diode 35 in Richardson with a switched overcharge-protection circuit, as taught by Lai, with the predictable result of cutting off recharging of jump starter batteries 22 from vehicle battery 28 in the event an over voltage protection threshold is crossed. See Ex. 1003 ¶ 174. Patent Owner’s argument that Richardson teaches away is not persuasive. Richardson’s teaching of recharging techniques supports the combination with Lai, rather than teaches away, because a system such as Richardson’s that permits recharging would have a need for safety protection and excessive recharging prevention. Further, claim 11 does not require preventing recharging in every situation, but rather only prevents recharging of “a normal voltage of the battery.” Ex. 1001, 6:11–12. In any event, Richardson does not criticize, discredit or discourage investigation into preventing recharging. See In re Fulton, 391 F.3d 1195, 1201 (Fed.

    “with Petitioner that the ’236 patent is not entitled to the 2014 priority date of the original application, or any date earlier than April 21, 2021, which is the filing date of the ’236 patent. Whether the Specification complies with the written description requirement calls for a comparison of the scope of the claim with the scope of the description to determine whether the inventor has demonstrated possession of the claimed invention. See Ariad, 598 F.3d 1336 at 1353; Power Oasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1306 (Fed. Cir. 2008). The independent claims of the ’236 patent each require (1) a load detection sensor “configured to detect presence of a vehicle battery” and (2) a reverse polarity sensor “configured to detect polarity of a vehicle battery.” Ex. 1001, 5:16–27 (claim 1), 6:7–22 (claim 13), 6:65–7:13 (claim 18), 8:1– 15 (claim 23). The Specification of the ’236 patent does not expressly disclose both a load detection sensor and reverse polarity sensor configured to perform the recited functions. Instead, the Specification identifies a single circuit, the “automatic detection module,” that “can automatically detect[] whether the load is detected” and “whether the electrode is connected with the automobile storage battery reversely.” Ex. 1001, 2:51–54. We are persuaded by Petitioner’s arguments that the disclosure of a single circuit capable of performing two functions does not demonstrate the inventors had possession of an invention that requires two separate sensors configured to perform separate functions as recited in the claims. See Ariad, 598 F.3d 1336 at 1352 (“[A] description that merely renders the invention obvious does not satisfy the [written description] requirement.”); Purdue Pharma L.P. v. Faulding Inc., 230 F.3d 1320, 1323 (Fed.

For all of the foregoing reasons, we agree with Petitioner that the Specification of the ’236 patent does not provide adequate written description support for distinct “load detection” and “reverse polarity” sensors, and, therefore, the challenged claims are not entitled to a priority date earlier than April 21, 2021, the filing date of the ʼ236 patent.” slip op. at 12

Petitioner asserts that a person of ordinary skill in the art at the time of the alleged invention would have had “at least a Bachelor’s Degree in a relevant engineering discipline such as electrical engineering and at least two years of relevant experience in the design and/or development of automotive electrical systems, or a Masters or more advanced degree in a relevant engineering discipline such as electrical engineering.” Pet. 5. Dr. Wood’s testimony supports Petitioner’s assertion. See Ex. 1003 ¶ 45. We adopt Petitioner’s description of an ordinarily skilled artisan as consistent with the ’077 patent and the asserted prior art.” slip op. at 13

    “[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.” Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

    “Conclusion About Obviousness for Claim 1 For the reasons discussed above, Krieger teaches the invention covered by claim 1. See supra §§ III.D.2(a)–(g). Hence, Petitioner has shown by a preponderance of the evidence that claim 1 is unpatentable under § 103 as obvious over Krieger.” slip op. at 27

    “1. Principles of Law In an inter partes review, the petitioner bears the ultimate burden of persuasion to show unpatentability, which never shifts to the patent owner. Dynamic Drinkware LLC v. National Graphics, Inc., 800 F.3d 1375, 1379– 1380 (Fed. Cir. 2015). “However, when a patent owner attempts to antedate an asserted prior art reference, the patent owner takes on a temporary burden of production.” Medtronic, Inc. v. Teleflex Innovations S.À.R.L., 68 F.4th 1298, 1303 (Fed. Cir. 2023) (citing Dynamic Drinkware, 800 F.3d at 1378– 79)). “Once that burden is met, the burden shifts back to the petitioner.” Id. “[A] patent’s claims are not entitled to an earlier priority date because the patentee claims priority. . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120,” including a written description in the earlier-filed application that satisfies § 112. In re NTP, Inc., 654 F.3d 1268, 1276–77 (Fed. Cir. 2011) (citations omitted)); see also Research Corp. Techs., Inc. v. Microsoft Corp., 627 F.3d 859, 870–71 (Fed. Cir. 2010). “[T]he hallmark of written description is disclosure,” and “the test [for satisfaction of the written description requirement] requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). The written description “must ‘clearly allow persons of ordinary skill in the art to recognize that [the inventor] invented what is claimed,’” and “reasonably” convey to those skilled in the art “that the inventor had possession of the claimed subject matter as of the filing date.” Id. (alteration in original). Stated another way, “one skilled in the art, reading the original disclosure, must immediately discern the limitation at issue in the claims.” Purdue Pharma L.P. v. Faulding Inc., 230 F.3d 1320, 1323 (Fed. Cir. 2000). To provide sufficient written description support, “[a] ‘disclosure” slip op. at 13

    “3. Reason to Combine Petitioner contends it would have been obvious to a person of ordinary skill in the art to combine (1) Eckhardt’s method of disinfecting skin using any light source that emits light capable of sterilization or disinfection, with (2) Sosnin’s KrCl or XeBr light sources, which generate photons having a wavelength of 222 nm and 282 nm, respectively. Pet. 21– 22 (citing Ex. 1003 ¶¶ 40, 81; Ex. 1004 ¶¶ 31, 69; Ex. 1005, 1547). Petitioner contends a person of ordinary skill would have been motivated to combine the teachings of Eckhardt and Sosnin for several reasons: (1) Eckhardt’s teaching of using any light source capable of sterilization or disinfection, and specifically “narrow spectrum light (e.g., a line spectrum)” would have suggested to a person of ordinary skill in the art to incorporate other well-known germicidal UV light sources like Sosnin’s, and both references teach that their light sources kill bacteria; (2) a person of ordinary skill would have implemented Eckhardt’s high-level disclosure of using UV- C light to disinfect skin with Sosnin’s 222 nm excimer lamp because Sosnin’s lamp’s wavelength is within the range of 220 to 310 nm suggested by Eckhardt; (3) the effectiveness and relative safety of directing UV-C light of 222 nm on bare skin for disinfection was already understood by persons of ordinary skill in the art, even though there was general caution against exposing skin to excessive UV radiation. Pet. 22–24 (citing Ex. 1003 ¶¶ 40, 81–92; Ex. 1004 ¶¶ 5, 31, 69, 70; Ex. 1005, 1545–47; Ex. 1011 ¶¶ 28, 40; Ex. 1013 ¶ 8; Ex. 1015, 2:22–67; Ex. 1016, 2:23–26; Ex. 1017, 58).” slip op. at 25

    “with our analysis of the effective filing date of original claims 12–18 that Patent Owner does not meet its burden to demonstrate the inventor’s possession in the ’626 provisional of generating photons of at least two single line wavelengths. Having considered the additional disclosures of the ’626 provisional Patent Owner points to in its RMTA (see RMTA 9), we find that none of these disclosures describe using both 222 nm and 254 nm single line wavelengths. See Ex. 1008 ¶¶ 8, 12, 27, claim 9; Ex. 2047, 6–9. For example, the recitation of “apparatus that consists of a NUV source, ESP, ozone generator, mercury lamps, and humidifier with controls as defined in claims 3–8 and any combination therein” in claim 9 of the ’626 provisional generally identifies various sources that may be used, but would not have indicated to a person of ordinary skill that the inventor had possession of generating single line wavelengths of 222 nm and 254 nm. Mr. Lawal’s testimony supports this finding. Ex. 1053 ¶¶ 1–12. Accordingly, we determine that Patent Owner does not meet its burden to demonstrate written description support for generating photons of at least two single line wavelengths, in claims 19–25 of its RMTA.19 Because Patent Owner has not satisfied the statutory and regulatory prohibition against introducing new matter in the revised proposed substitute claims, we deny the RMTA as to claims 19–25. 35 U.S.C. § 326(d)(3); 37 C.F.R. § 42.221(a)(2)(ii). Accordingly, we need not reach the patentability challenges Petitioner raises with regard to claims 19–25.” slip op. at 77
