“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.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner
“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

“However, we find that Fang is not cumulative of the art considered by the Examiner in prosecution. Further, Patent Owner does not direct attention to, and we do not see, how or where the Examiner considered Khalil for teaching removing the air line for directly connecting the external pump to connecting a pump housing to a diaphragm housing” (POPR 50), the Examiner specifically found that Khalil did not teach the diaphragm housing being fixed to a recessed surface of the pump housing (Ex. 1002, 24), for which Petitioner relies on Fang (Pet. 37). And we note that Petitioner relies on Fang for the element the Examiner found was not taught by the prior art, including Khalil. Ex. 1002, 24; Pet. 37. Accordingly, we determine that discretionary denial is not warranted because the asserted combinations, all of which include Fang, were not previously presented to the Office. Because we determine that part one of the framework is not satisfied, we need not, and therefore do not, turn to part two of the analysis, which concerns whether Petitioner demonstrates that the Office erred in a manner material to the patentability of the challenged claims. 5.

“We find that Holmberg expressly contemplates using its wall box within multi-dwelling units, notes that multi-dwelling wall boxes in the prior art were “typically provided” on every floor, and discloses that the multi-dwelling wall boxes would contain optical couplings for each resident on a given floor. Ex. 1004 ¶¶ 7, 34; Pet. Reply 8–10. In view of these disclosures, we credit the testimony of Dr. Kiaei that one of ordinary skill in the art would have sought to use Holmberg’s wall box in multi-dwelling units and would have seen a need to access the area behind spice tray 230 to connect and disconnect subscribers. Ex. 1003 ¶ 92; Ex. 1033 ¶¶ 7–8. Moreover, even if Holmberg were limited to mid-span locations and distributing drop cables, as opposed to distribution cables for individual subscribers, as asserted by Patent Owner, Patent Owner does not dispute that a technician would still need periodic access to the area behind splice tray 230 in these mid-span devices.

Thus, whether used in the manner contemplated by Petitioner or Patent Owner, Petitioner persuasively demonstrates that access to the space behind splice tray 230 in Holmberg would be necessary. With access behind splice tray 230 required, Petitioner persuasively demonstrates that one of ordinary skill in the art would have seen a benefit to replacing Holmberg’s fasteners or screws with a hinged connection, such as that disclosed in Battey, to allow easier access to the area behind the splice tray.

“art would not have modified Kurita in view of Lemoff because Lemoff positions the signal emitters near the fiber to emulate WDM without the need for an external optical multiplexer or a similar device and discourages using optical wavelength multiplexers for short distances because the complexity of the design is often cost prohibitive (PO Resp. 47–48), Lemoff does not appear to limit the usefulness of the fiber connector to any particular optical signal transmission distance. Petitioner relies upon Lemoff for a suggestion to combine Lemoff’s fiber connector configuration teachings with Kurita’s multiplexer teachings to enable fibers to be plugged Fig. 2) (Pet 29, 31; Reply 17–18). Regarding Patent Owner’s argument that one of ordinary skill in the art would not have combined Lemoff’s receptacle and ferrule with discrete components in Kurita because the fiber would need to be manually fixed and aligned with or without a ferrule and, therefore, would serve no purpose (PO Resp. 48), Lemoff’s fiber connector appears to fix and align the fiber adequately for wavelength division multiplexing without manual fixation or alignment being required (Ex. 1006, 5:65–6:2, Fig. 2; Reply 18). The challenged claims do not require any greater degree of fixing and alignment than that provided by Lemoff’s fiber connector. Regarding Patent Owner argument that Lemoff’s device is not physically combinable with Kurita’s WDM multiplexer due to Lemoff’s device’s small size (PO Resp. 47–48; Reply 17–18), “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.... Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art” (In re Keller, 642 F.2d 413, 425 (CCPA 1981)). Accordingly, we are not persuaded by Patent Owner’s argument.” slip op. at 26

“stopped single optical fiber because fixing it in place does not passively align it with the optical components (PO Resp. at 35–37) is not persuasive because fixing Kurita’s fiber (40) in place in accord with Lemoff’s teaching regarding the ferrule (255) inserted until being stopped by the receptacle (260) (Ex. 1006, 5:50–6:15, Fig. 2) would align Kurita’s optical array (20), and lens (30)) (Ex. 1004 Fig. 3) passively in the same manner that Lemoff’s ferrule (255), after being inserted until stopped by the receptacle (260), passively aligns the optical fiber (250) with the optical components (optical imaging element 220 and light emitters within emission apertures 120) (Ex. 1006, 5:50–6:15, Fig. 2; Reply 15–16). Regarding Patent Owner’s argument that the light from each of Kurita’s lasers (11) depicted in Figure 3 cannot pass through a separate focusing lens (30) pie shaped sector because the lasers (11) and collimating lenses (21) are arranged linearly rather than being arranged about a circular axis (PO Resp. at 37–42), we do not agree. Claim 1 requires “focusing means having n separate radial sectors on its surface, and each of said n collimated beams passes through a separate one of said n sectors of said focusing means” (Ex. 1001, 5:34–37), claim 2 requires “four lasers and four collimating lenses are each formed in a two-dimensional, two by two array [centered on the focal axis of lens 30], wherein said focusing means is a single focusing lens, and wherein each radial sector is a pie-shaped quadrant” (id. at 5:41–44), and claim 7 requires “focusing means having four separate quadrants on its surface, and each of said four collimated beams passes through a separate one of said quadrants of said focusing means” (id. at 6:35–38). Kurita meets those claim requirements. Kurita’s two by two array (10A) of lasers (11), collimating lens (21) array (20), and focusing lens (30) are shown in Kurita’s Figure 3 (cropped) as follows: The image is a portion of Kurita’s Figure 3 showing Kurita’s laser array, collimating lens array, and focusing lens (30). Relative to a point at the center of the laser array (10A) or the collimating lens array (20), each laser (11) and each collimating lens (21) is in a separate quadrant that can be a quadrant of a circle (pie-shape) on lens 30 (Reply 12– 13, Ex. 1003 ¶¶ 85–91).” slip op. at 23
