RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“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

“patent describes that “angular position transducer 78 is placed on top of swing leg pivot shaft 24” and that “pivot shaft 24 is rotationally fixed to the connector plate and duplicates the angular movements of swing leg 20 about the pivot shaft.” Ex. 1001, 12:15–16, 12:20–22, Figs. 5, 7. The ’723 patent also describes that “[a]ngular position transducer 78 is mounted inside . . . protective can 90 . . . which is bolted to hinge bracket 28 via an upright holding arm 92” and that “trigger pin 94 projects upwardly from the top surface of pivot shaft 24 and cooperates with angular position transducer 78 to generate an angular position signal.” Id. at 12:28–33, Fig. 5. These descriptions expressly convey that angular position transducer 78 is on pivot shaft 24 and mounted inside protective can 90 that is bolted to hinge bracket 28.

“through the undermold.” The term “aperture only partially extending through said undermold” was added to the claims of the ’254 parent application by amendment. Ex. 1021, 103–105; Ex. 1020, 6:60–8:47. With this amendment, the claims of the ’254 patent align with Figure 7, reproduced below. Figure 7 of the ’254 Patent (Figure 7 of the ’153 patent is identical to Figure 7 of the ’254 patent except for minor stylistic changes). As can be seen, the aperture occupied by drop line 12 extends partially through the undermold to compression lug 20 while the aperture occupied by feeder cable 14 extends completely through the undermold. This suggests a construction of “aperture extending partially through the undermold” where such aperture does not extend completely through the undermold. Such a construction of “aperture extending partially through the undermold” is consistent with the plain meaning of “extending partially.”” slip op. at 62

“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

T- Mobile USA, Inc., 522 F.3d 1299, 1306 (Fed. Cir. 2008). The test for determining compliance with the written description requirement under § 112(a) is whether the original disclosure of the earlier-filed application reasonably would have conveyed to one with ordinary skill in the art that the inventor had possession of the claimed subject matter at the time of the earlier-filed application. Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc).

We agree with Petitioner there does not appear to be support for limitation [1(j)] in the ’653 application. We find that the disclosure of the ’653 application—limited to general teachings of a smart card, an operating system, and a smart card manager—is insufficient to show possession of limitation [1(j)]. See Ex. 2001 (’218 patent), 4:47–56. As we explained above, “[e]ntitlement to a filing date does not extend to subject matter which is not disclosed but would be obvious over what is expressly disclosed.” Lockwood, 107 F.3d at 1571−72. The ’653 Application contains no disclosure of replacing applications, even if the disclosure might render such replacing obvious, it is not sufficient to show the possession required to establish entitlement to a priority date.

“We agree with Petitioner that, even if the applications were stored in “generic memory” as Patent Owner contends, Zhu provides adequate security and would not undermine Petitioner’s motivation to combine. See Intel, 61 F.4th at 1380 (“It’s not necessary to show that a combination is the best option, only that it be a suitable option.”). Indeed, Zhu addresses the problem Patent Owner contends it would cause in the combination.3 As Zhu 3 Patent Owner argues that Petitioner should be precluded from discussing Zhu’s encryption embodiment because it was not raised in the Petition. See Sur-Reply 6–7. We disagree. The claims do not recite anything about how the data should be stored. Thus, it is not surprising that the Petition did not address it. Patent Owner raised the teaching away argument regarding the security of the data. See PO Resp. 12–16. Petitioner relies on the exact same mapping, same motivation, and same arguments why Zhu accounted for certain limitations. See Reply 4–11. Petitioner’s Reply merely explained that Zhu did address the problem Patent Owner contended would “teach away” from the combination. Indeed, Patent Owner was aware of Zhu’s teachings and addressed them in their Patent Owner Response. The Federal recognizes, “[l]oading one of the smart card applications already resident on the smart card to another memory location on the mobile device can provide sufficient memory for the selected smart card application, but can also create a security problem.” Ex. 1006 (Zhu), 3:25–34. To address this problem, Zhu proposes encrypting these applications in generic memory which “reduces the possibility of unauthorized access to the information.” Id. at 3:59–61, 8:30–55, 9:28–33; Ex. 1033 (Smith Supp. Decl.) ¶¶ 5–6. Although acknowledging this disclosure, Patent Owner’s expert, Dr. Weaver, testifies that Zhu’s encryption is inadequate and that encryption would have certain drawbacks. See Ex. 2002 (Weaver Decl.) ¶ 69. We find this testimony, which directly contradicts the teachings of Zhu that encryption is an adequate solution, lacks sufficient support to be entitled to much weight. Dr. Weaver provides no citations to support his contention that a person of ordinary skill at the time of the invention would find encryption so inadequate or problematic as he now contends. Moreover, we find that Dr. Weaver’s testimony on cross examination provides an additional, independent basis to give this testimony little weight. On cross examination, Dr. Weaver contended that there was nothing uniquely inadequate about the particular encryption scheme disclosed in Zhu, but rather that his “opinion was more general, that encryption schemes known in the 2012 time frame were all breakable with computing power and time,” and thus, inadequate Circuit has explained that “the petitioner in an inter partes review proceeding may introduce new evidence after the petition stage if the evidence is a legitimate reply to evidence introduced by the patent owner.” Anacor Pharm., Inc. v. Iancu, 889 F.3d 1372, 1380–81 (Fed. Cir. 2018). That is the case here, so we find that Petitioner’s arguments and evidence regarding Zhu’s encryption are proper. for storing payment applications in a mobile device’s general memory. Ex. 1027 (Weaver Tr.), 26:11–23; see also id. at 23:3–8 (“[D]oes encryption ever provide a sufficiently high security to permit storing payment application on a mobile device’s general memory? A. No”); 24:15–25:23 (testifying all publicly known encryption schemes in 2012 were breakable). However, when confronted with the fact that the ’724 patent discloses storing payment application on general baseband memory using an encryption method that was breakable, id. at 26:24–29:7, Dr. Weaver testified that this encryption method was sufficient to allow storing payment applications in general baseband memory even though it was “not perfectly secure,” id. at 29:8–14. Dr. Weaver provides no explanation or rationale why the encryption method in the ’724 patent, which he admits suffers from the same drawbacks he identified with respect to Zhu, is sufficient, but other encryption methods would not be sufficient. In its Sur-reply, Patent Owner attempts to rehabilitate Dr. Weaver’s testimony with justifications and qualifications not found in his original testimony. Sur-Reply 7–8. Yet, Dr. Weaver’s testimony discussed above was clear and unequivocal. See Ex. 1027 (Weaver Tr.), 24:15–29:14. Patent Owner made no effort to redirect his testimony at his deposition, so it cannot now do so through mere attorney argument. We find the inconsistency between Dr. Weaver’s treatment of Zhu and his treatment of similar disclosure in the ’724 patent exposes the insufficient reasoning supporting his opinions regarding the adequacy of Zhu’s use of encryption in the combination. Accordingly, we give no weight to his testimony that a skilled artisan would not have combined Zhu with a Buhot/GPC system due to security concerns. In contrast, we find the testimony of Mr. Smith regarding the use of encryption and the tradeoffs with the benefits of adopting Zhu’s memory management technique, which he offers in his Supplemental Declaration, to be well-reasoned, consistent with the disclosure of Zhu and the ’724 patent4, and entitled to substantial weight. See Ex. 1033 (Smith Supp. Decl.) ¶¶ 4–15. As Petitioner recognizes, “‘[a] given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.’” Allied Erecting & Dismantling Co. v. Genesis Attachments, LLC, 825 F.3d 1373, 1381 (Fed. Cir. 2016). As Mr. Smith and Dr. Weaver testified, decryption without access to the security keys is an extremely computationally intensive and time-consuming process. Ex. 1033 (Smith Supp. Decl.) ¶¶ 6–8; Ex. 1027 (Weaver Tr.), 23:17–25:2; see also Ex. 10175, 132. Mr. Smith testifies that the benefits of using encryption would be sufficient to resolve the security concerns Patent Owner raises, and that any burden of generating a certificate would be outweighed by the benefits of using encryption and the memory advantages Zhu’s technique would offer.

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

“19 We also determine that claim 19 does not particularly point out and distinctly claim the invention sought to be patented, as required by 35 U.S.C. § 112(b), because “the microorganisms” in element [19B] lacks antecedent basis.” slip op. at 78
