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

“Regarding the “first static unidirectional electric drift field to aid the movement of minority carriers” limitation, Petitioner relies on the parent file history and cited references, arguing that “Payne’s downward-sloping graded-dopant concentration aids the movement of minority carriers from the surface layer to the substrate to the same extent to which Applicant relied on the prior art and admitted to the Patent Office that such carrier movement would occur under the same scenario.” Pet. 23. Petitioner also asserts that the direction in which carriers are forced with the concentration profile disclosed in Payne is downward, toward the substrate and away from the surface. Pet. 23–28 (quoting and citing Ex. 1046, 237–238, 253–254, 289– 290; citing Ex. 1003 ¶¶ 95–106; Ex. 1005, 5:7–17, 5:44–55; Ex. 1009, 2:11– 16, 2:67–3:18, Fig. 2; Ex. 1010, 2:27–32, 5:14–22; Ex. 1013, 431; Ex. 1030, 24).
