“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).

“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

“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

“1. Level of Ordinary Skill in the Art Petitioner asserts that one of ordinary skill in the art “would have at least a Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related field, and 2-3 years of experience in memory system design,” or, alternatively, “a Master’s degree in one of those fields and 1-2 years of relevant experience.” Pet. 9 (citing Ex. 1003 ¶¶ 26–29). 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 in the event that trial is instituted.” Prelim. Resp. 7.

“Petitioner asserts that “that no construction is necessary for any terms for the purposes of this Petition as the challenged claims are invalid under any reasonable construction.” Pet. 9. Patent Owner states that “the Board need not construe any claim term in a particular manner to arrive at the conclusion that the Petition is substantively deficient.” Prelim.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable
“to combine Johnson and Moss is inadequate. See Prelim. Resp. 20–24. We tend to agree. In the “Motivation to Combine Johnson and Moss” section, the Petition first asserts that “Johnson and Moss are in the same field of endeavor,” which is insufficient without more to provide a motivation. See, e.g., Sisvel Int’l S.A. v. Sierra Wireless, Inc., 82 F.4th 1355, 1364 (Fed. Cir. 2023). The Petition then asserts that “[t]o provide enhanced flexibility, [one of ordinary skill in the art] in possession of Johnson would look to Moss to incorporate a plurality of delay elements to the data strobe signal.” Pet. 22. This is not persuasive because (a) Petitioner argues that Johnson already provides a plurality of delay elements, (b) Petitioner fails to explain where or how additional delay elements from Moss would be added to Johnson, and (c) Petitioner fails to explain how or why the modification would “provide enhanced flexibility,” or even what “enhanced flexibility” might mean in 9 “a first sampling circuit to sample the first delayed data signal based on the strobe signal” 10 “a second sampling circuit to sample the second delayed data signal based on the received strobe signal” this context. Petitioner also argues that “Moss further discloses that the size of the data path – i.e. the number of data pins in each data path – is a design choice well within the knowledge and ability of a POSITA, and expressly recites examples of 4, 8, and 16-bit wide data paths.” Pet. 23. We agree that varying the width of the data path would have been within level of ordinary skill and would have depended on the particular application, but the Petition fails to explain how or why that would have made it obvious to incorporate various elements of Moss into Johnson.” slip op. at 19

“Petitioner contends that “[a] POSITA would have been motivated to incorporate the termination circuitry disclosed in Greeff with the system of Meaney to achieve enhanced system performance and reliability.” Pet. 53 (citing Ex. 1002, app. A at 82). As support, Petitioner asserts that “Greeff’s termination circuitry ensures proper signal integrity and reduces reflections in high-speed data transmission systems.” Id. (citing Ex. 1006, 1:28–31, 4:10–12, 8:3–5; Ex. 1002, app. A at 82). Petitioner further asserts that “Meaney’s calibration techniques, when applied to the termination resistance and transistor drive strength of Greeff, would ensure that these parameters remain optimal throughout system operation.” Id. (citing Ex. 1002, app. A at 82); see also id. at 54 (“A POSITA would have found it obvious to apply Meaney’s calibration process to Greeff’s termination circuitry in order to optimize the termination resistance and drive strength of the termination circuitry.”). Petitioner adds that “[a] POSITA would have had a reasonable expectation of success in combining Meaney and Greeff.” Id. at 54. According to Petitioner, “[t]he integration of Greeff’s termination circuitry into Meaney’s system would have been straightforward and cost-effective,” any “required modifications are minimal, and the results of the combination are predictable, given the complementary nature of the technologies.” Id. (citing Ex. 1002, app. A at 82). Patent Owner does not dispute Petitioner’s analysis for this limitation. See Prelim. Resp. Based on Petitioner’s argument and evidence, we are persuaded that Petitioner has shown sufficiently for purposes of this Decision that its proposed combination of Meaney and Greeff teaches or suggests the recited “circuitry” of limitation 17a. We also are persuaded that Petitioner’s proffered reasoning for modifying Meaney’s system to include Greeff’s termination circuitry, namely, to ensure proper signal integrity and reduce reflections, is sufficient to support institution.

RulingsInstitution decision- PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Decided for petitioner
“the district court litigation was dismissed with prejudice on January 17, 2025. Prelim. Reply 1; Ex. 3001, 10. Accordingly, there is presently no parallel litigation to consider under Fintiv. Nevertheless, Patent Owner argues that “the dismissal of the complaint does not eliminate the relevance of the many Fintiv factors.” Prelim. Sur-reply 1. We disagree. Fintiv indicates that “[a] district court stay of the litigation pending resolution of the PTAB trial allays concerns about inefficiency and duplication of efforts.” Fintiv, Paper 11 at 6 (emphasis added). Here, we have not a stay of the district court litigation, but its dismissal with prejudice. See Ex. 3001, 10. Thus, concerns about inefficiency and duplication of efforts are not merely allayed, but are instead obviated.” slip op. at 11

“the same or substantially the same prior art or arguments previously were presented to the Office.” 35 U.S.C. § 325(d). The Board analyzes this issue under the following two-part framework set forth in the precedential Advanced Bionics case: (1) whether the same or substantially the same art previously was presented to the Office or whether the same or substantially the same arguments previously were presented to the Office; and (2) if either condition of [the] first part of the framework is satisfied, whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of challenged claims. Advanced Bionics, LLC v. MED-EL Elektromedizinische Geräte GmbH, IPR2019-01469, Paper 6, 8 (PTAB Feb. 13, 2020) (precedential). As an initial matter, there is no dispute that at least Garecau and TealLevel were not previously presented to the Office. See Prelim. Reply 2 (“Grounds 5 and 6 are based entirely on new references and therefore could not mirror [the prior art combinations asserted] by the Examiner.”); see generally Prelim. Resp. Garecau and TealLevel are the only two references in Grounds 5 and 6. See Pet. 3. Patent Owner does not argue that Garecau and TealLevel, or the arguments presented in these grounds, are the same or substantially the same as art or arguments previously before the Office. See generally Prelim. Resp. 10–16 (making no § 325(d) arguments based on Garecau or TealLevel or directed to Grounds 5, 6). Accordingly, because there is no dispute that Grounds 5 and 6 present art and arguments that were not previously before the Office, in this case we find that § 325(d) is not slip op. at 13

Petitioner ultimately bears the burden of persuasion to prove unpatentability of each challenged claim by a preponderance of the evidence. 35 U.S.C. § 316(e). This burden never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). The Board may authorize an inter partes review if we determine that the information presented in the Petition and Patent Owner’s Preliminary Response (and any additional authorized briefing of record) shows a reasonable likelihood that Petitioner will prevail with respect to at least one of the claims challenged in the petition. 35 U.S.C. § 314(a).” slip op. at 16
- Skill levelSkill level petitioner adoptedDecided for petitioner
“We additionally agree with Petitioner that the level of skill proposed by both parties is substantially the same. Specifically, both parties propose a similar education level (Bachelor’s degree in a relevant field of science or engineering) and similar experience (1–2 years of industry experience, including knowledge of sensor design and application development). We observe that in Patent Owner’s proposal, the recited experience is possibly a bit more specific than in Petitioner’s proposal (e.g., it recites “commercial app development” experience and some programming experience). See Prelim. Resp. 3 (emphasis added). However, at this stage and absent argument to the contrary, we discern no material difference between the parties’ proposals. Petitioner’s proposal is consistent with the level of ordinary skill reflected in the prior art references of record, and unlike Patent Owner’s proposal at this stage, is supported by declarant testimony. See Okajima, 261 F.3d at 1355. Accordingly, for purposes of this decision, we apply Petitioner’s definition of the person of ordinary skill in the art. We note, however, that were we to adopt Patent Owner’s proposal, the outcome of this Decision would be the same.” slip op. at 19
