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.

- 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

“the application describe the claim limitations exactly,” the application must demonstrate to persons of ordinary skill in the art that the applicants invented a composition including those limitations. Wertheim, 541 F.2d at 262. On its face, the range of “at least 0.01 wt. %” encompasses a range that is broader than 0.01–35 wt. %, and Patent Owner does not sufficiently explain why a person of ordinary skill in the art would understand from merely a disclosure of 35 wt.% that the inventors were in possession of the entire claimed range for copper, cobalt, or nickel in the magnesium composition.” slip op. at 11

“On this record, the term “at least 0.01 wt. %” in the ’740 patent encompasses values for nickel, copper, and cobalt that are higher than the 35 wt. % (nickel and copper) and 20 wt. % (cobalt) limits outlined in the parent and grandparent applications. Accordingly, we determine that there is a reasonable likelihood that claim 19 of the ’740 patent is not entitled to the benefit of the filing dates of its priority applications. Challenged claims 20–61 and 63–75 depend from claim 19 and there is no argument presented that these claims have independent written description support in Doud. For example, there is no evidence presented that any of these dependent claims narrow the ranges for each of copper, nickel, and cobalt recited in in the ’295 application for these claims.7 Accordingly, for purposes of this Decision, we apply Doud as prior art to challenged claims 19–61 and 63–75.” slip op. at 12

“as the ’740 patent. For example, Doud and the ’740 patent both disclose a method of forming a novel magnesium composite that includes melting an AZ91D magnesium alloy containing 90 wt. % magnesium, 9 wt. % aluminum, and 1 wt. % zinc. Ex. 1005 ¶¶ 45, 47; Ex. 1001, 21:43–51, 22:48–53, 33:32–43, 34:9–12. To this alloy is added either 7 wt. % nickel or 10 wt. % copper. Ex. 1005 ¶¶ 45, 47, 53, 57; Ex. 1001, 21:48–51, 22:53–56, 33:35–36, 34:12–13. These additives are mixed in the magnesium alloy at a temperature that is less than the melting point of copper or nickel, and the casting is then cooled. Ex. 1005 ¶¶ 45, 47, 53, 57; Ex. 1001, 21:51–54, 22:56–58, 33:35, 34:12-13. Doud reports that nickel and copper, when added to molten magnesium, will form Mg2Ni and CuMg2 intermetallic, galvanically-active, in situ precipitates. Ex. 1005 ¶¶ 12–13. Doud discloses that the dissolution rate of the resulting casting material is either 325 mg/cm2-hr (nickel) or 50 mg/cm2-hr (copper) in a 3% KCl solution at 90° C. Ex. 1005 ¶¶ 45, 47, 53, 57; Ex. 1001, 21:60–62, 22:61–63, 33:41–43, 34:15–17. Doud also discloses that the average particle diameter of the additives used in the invention is generally “at least about 0.1 microns” and “typically no more than about 500 microns.” Ex. 1005 ¶ 6. Petitioner explains how the identified disclosures of Doud anticipate independent claim 19. Pet. 39–40. Petitioner also identifies where the limitations of dependent claims 20–61 and 63–75 are disclosed in Doud. Id. at 41–45.

The scope of the claims must be less than or equal to the scope of the enablement. The scope of enablement, in turn, is that which is disclosed in the specification plus the scope of what would be known to one of ordinary skill in the art without undue experimentation.” National Recovery Techs.

In particular, we are persuaded based on the record at this stage of the proceeding that the Specification does not enable the full scope of the claims. The Specification focuses on dolastatin/auristatin derivatives and does not describe novel ADCs having non-dolastatin/auristatin derivative drug moieties. Ex. 1001, Abstract. For example, the Specification states that “there is a clear need in the art for dolastatin/auristatin derivatives having significantly lower toxicity, yet useful therapeutic efficiency [sic]” and purports that “[t]hese and other limitations and problems of the past are addressed by the present invention.” Id. at 4:25–29 (emphasis added).

Based on this disclosure, we concluded that “the Korean Application’s description of cracks in the ‘coating layer’ does not necessarily mean that those cracks are confined to the outer zinc layer and fail to reach the inner alloy layer.” Id. at 10.” slip op. at 4

“article whose surface has at least one empty or concave part.” Id. at 11 (citing Ex. 1001, 1:66–67; Ex. 1007 ¶ 15). Patent Owner agrees. PO Resp. 15. The ’253 patent states that “[t]he term ‘hollow body’ is understood to mean any article whose surface has at least one empty or concave part.” Ex. 1001, 1:66–67. Where an inventor defines specific terms used to describe an invention, we will give effect to those definitions, as long as they are set out “with reasonable clarity, deliberateness, and precision,” “so as to give one of ordinary skill in the art notice of the change” in meaning. In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994). Here, the phrase “is understood to mean,” as used in the ’253 patent, signals that the inventor presents a clear, deliberate, and precise definition. Accordingly, we interpret “hollow body” as having the definition given it in the ’253 patent, “any article whose surface has at least one empty or concave part.”” slip op. at 6

“supporting its proposed construction of “incorporate” as “insert.” First, Petitioner argues that the language of the ’253 patent requires a construction of “incorporating” as encompassing “inserting” rather than as limited to “attaching.” Reply 2–4. Both parties argue that the “incorporating” recited in the challenged claims must occur before the mold closes to form the hollow body. PO Resp. 16; Reply 2–3. We agree. Ex. 1001, 6:2–14 (“. . . after said step of incorporating, closing said mould . . .”). Thus, it is important to note the processes that the ’253 patent describes as occurring before, during, and after mold closure. Because “incorporating” must occur before mold closure, the process of “incorporating” may not be limited to any process that the patent describes as occurring during or after mold closure. Petitioner is correct that the ’253 patent describes a process in which a preassembled structure for supporting an accessory “may . . . be fastened by welding to the wall of the hollow body, upon closing the mould,” i.e., during, not before, mold closure. Ex. 1001, 4:23–30. Thus, the language of the ’253 patent does not support construing the term “incorporating” as limited to “attaching.” Petitioner also argues that both parties agreed in the related infringement suit in District Court that the proper construction of “incorporating” under the Phillips standard, used in that forum, was “inserting.” Reply 7–8 (citing Ex. 1010, at Ex. A, 4). Specifically, in that litigation, Patent Owner agreed that the correct construction of “incorporating at least one of an accessory or a duct within the hollow body” was “inserting an accessory or duct into the hollow body.” Ex. 1010, at Ex. A, 4. Here, we apply the broadest-reasonable-interpretation standard. 37 C.F.R. § 42.100(b) (2016). “The broadest reasonable interpretation of a claim term may be the same as or broader than the construction of a term under the Phillips standard. But it cannot be narrower.” Facebook, Inc. v. Pragmatus AV, LLC, 582 F. App’x 864, 869 (Fed. Cir. 2014) (non-precedential). Here, for the term “incorporating,” Patent Owner’s proposed broadest reasonable interpretation (“attaching”) is narrower than the Phillips construction Patent Owner has advanced (“inserting”). Thus, “attaching” cannot be the broadest reasonable interpretation of “incorporating.” Other than Patent Owner’s proposed “attaching” construction, the only construction the parties have proposed either in this case or in the related District Court case is Petitioner’s proposed “inserting” construction. PO Resp. 15–20 (discussing only “inserting” and “attaching” constructions); Reply 2–9 (Petitioner arguing in favor of “inserting”); Ex. 1010, at Ex. A, 4 (both parties proposing “inserting”). The ’253 patent supports such a construction, because it describes at least some of its embodiments as involving only insertion of an object between the sheets that will form the hollow body before mold closure. Ex. 1001, 4:23–30. Accordingly, for the foregoing reasons, we adopt Petitioner’s proposed construction of “incorporating” as “inserting.”” slip op. at 10

“Finally, Patent Owner directs us to the testimony of Professor Tim Osswald as support for its view that “incorporate” should mean “attach.” PO Resp. 16 (citing Ex. 2001 ¶¶ 40–42). In relevant part, this testimony states that, “[a]fter reading the specification of the ’253 patent, one of ordinary skill in the art would understand and interpret the word ‘incorporating’ to mean ‘fastening’ or ‘attaching’ so that the accessory or duct becomes part of the hollow body.” Ex. 2001 ¶ 42. Professor Osswald does not cite any evidence in support of his testimony. “[C]onclusory, unsupported assertions by experts as to the definition of a claim term are not useful.” Phillips v. AWH Corp., 415 F.3d 1303, 1318 (Fed. Cir. 2005) (en banc). Accordingly, we give little weight to Professor Osswald’s statement regarding the proper construction of “incorporate.” See In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1368 (Fed. Cir. 2004) (“[T]he [PTAB] is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations . . . .” (citations omitted)).” slip op. at 9

“preform which has at least one opening for that purpose, to be applied to the inside surface of the wall of the expanded hollow body.” Id. at 3:62–4:3. Patent Owner argues that this teaching is insufficient to disclose attaching the surge cup to the wall of the hollow body before the mold closes. PO Resp. 23–24. We agree that Linden does not teach attaching its accessory to the inside wall of the fuel tank before the mold closes around the preform. Instead, in Linden, the mold halves are closed around the preform and the mandrel, and “a suitable blowing agent . . . is introduced under pressure” through the mandrel, causing the preform to expand to press “against the inside wall defining the mold cavity,” and only then is the holding means for the accessory displaced to be brought into contact with the inner wall of the expanded preform, welding the holding means to the wall. Ex. 1003, 7:27–55, 8:11–29, Figs. 1–3. But, as discussed above, we disagree with Patent Owner about the proper construction of “incorporating” in the challenged claims. Claim 1 requires only that an accessory or a duct be “incorporat[ed] . . . within the hollow body” before mold closure occurs, and we construe “incorporating” to mean “inserting,” without requiring “attaching.” Thus, it is unimportant that Linden fails to teach attaching the surge cup to the wall before mold closure. All that is required is that Linden disclose inserting the surge cup into the preform before mold closure, and Linden does disclose this. Id. at 3:62–4:3, 7:27–49, Figs. 1–3. The next question is whether Linden discloses “after said step of incorporating, closing [the mold] in a way which eliminates any interface between said at least one of said accessory or said duct and an external atmosphere outside of the hollow body.” As discussed above, Linden discloses closing the mold halves after placing the additional body within the preform. But Linden discloses that “[a]t its lower end the preform 28 is pressed around the mandrel 14 by virtue of closure of the mold halves 10a and 10b.” Id. at 7:40–42, Fig. 2. Because mandrel 14 is hollow, id. at 6:35–39; 6:46–54, it is not completely clear that closure of Linden’s hollow body around mandrel 14 necessarily eliminates any interface between the additional body inside Linden’s hollow body and the atmosphere outside the hollow body. On the other hand, the closure of the mold described in the ’253 patent occurs with blowing nozzle 6 “positioned between the two parts of the [mold],” and “blowing air is injected under pressure via the nozzle,” which is quite similar to the use of hollow mandrel 14 in Linden. Ex. 1001, 5:50–57. Given the similarity between Linden’s method and the method described in the ’253 patent, we determine that Petitioner has shown by a preponderance of the evidence that Linden discloses the limitation of claim 1 requiring the step of, “after said step of incorporating, closing [the mold] in a way which eliminates any interface between said at least one of said accessory or said duct and an external atmosphere outside of the hollow body.” The final question with respect to claim 1 is whether Linden discloses that the additional body incorporated within the hollow body “is supported by a preassembled structure which comprises at least one device configured to anchor said preassembled structure to an internal wall of the hollow body.” Petitioner argues that Linden’s “[h]olding means 24 is a preassembled structure” in which “leg members 44, 45” have “enlarged foot portion[s] 36.” Pet. 18 (citing Ex. 1003, 9:23–34). We agree. “[H]olding means 24 . . . substantially comprises first and second support or leg members 44, 45,” and “support or leg members 44, 45 are each provided with an enlarged foot portion 36 of substantially plate-like configuration.” Ex. 1003, 9:23–34. Even if Linden’s holding means 24 were not in the aggregate the recited “preassembled structure,” each leg member 44, 45, taken together with its respective foot portion 36 is. Ex. 1001, 4:26–28 (describing a “preassembled structure” as “for example, an arm provided with a tab for fastening to the wall of the hollow body”). Linden’s “foot portions 36 are pressed against the inside surface, which is still hot and thus plastic, . . . of the hollow body . . . thereby to produce a welded joint between the foot portions 36 and the inside surface.” Id. at 9:34–42. Petitioner has shown by a preponderance of the evidence that Linden discloses the limitation of claim 1 requiring that the accessory or duct be “supported by a preassembled structure which comprises at least one device configured to anchor said preassembled structure to an internal wall of the hollow body.”” slip op. at 19
