  • Disclosure Requirements (§112) › Written description (Ariad)Written description adequateEntitled to earlier dateDecided for patent owner

    “We consider the disclosures of the Provisional Application, which refer to cases 1 and 2, in which requests are redirected to an origin server for lower popularity content and to a parent server for medium popularity content at steps 522 and 524 as shown in Figure 5, respectively, wherein the edge server receives a redirect from the popularity service without a “followme” flag. See Ex. 1011 ¶¶ 43, 44. The Provisional Application also discloses that, by comparison, if there is a “follow-me” redirect sent to the edge server, it obtains and caches a resource as shown at step 528 for higher popularity content. Id. ¶ 44. On this record, as Patent Owner asserts, these disclosures are consistent with technical reasons provided in the Provisional Application for instructing the edge server not to cache unpopular resources. See Ex. 1011 ¶¶ 68–69. In light of these disclosures, we preliminarily find support for Dr. Shenoy’s testimony that, even with the words “instruction to not cache” are not literally recited in the Provisional Application, caching and not caching are alternative options that indicate the instruction to the edge server that will be implemented for each option. See Ex. 2014 ¶ 56. Further, these disclosures provide support for Dr. Shenoy’s testimony that the disclosures “reasonably convey to those skilled in the art that Patent Owner had possession of the edge server receiving an instruction to not cache the resource (and instead simply forward the redirect).” Id. In re Johnson states that “it is not true that the factual context out of which the question under § 112 arises is immaterial. Quite the contrary. Here, . . . the ‘written description’ in the [] specification supported the claims in the absence of the limitation, and that specification, having described the whole, necessarily described the part remaining.” See Johnson, 558 F.2d at 1019. This is consistent with M.P.E.P. § 2173.05(i) which states, “[i]f alternative elements are positively recited in the specification, they may be explicitly excluded in the claims.” M.P.E.P. § 2173.05(i). Further, “the failure of the specification to specifically mention a limitation that later appears in the claims is not a fatal one when one skilled in the art would recognize upon reading the specification that the new language reflects what the specification shows has been invented.” All Dental Prodx, LLC v. Advantage Dental Prod., Inc., 309 F.3d 774, 779 (Fed. Cir. 2002). Even though we do not discern that the Provisional Application explicitly discloses an “instruction to not cache,” at least on this preliminary record, and for the purposes of this Decision, there is positive recital of instructions to cache in the Provisional Application and Petitioner has provided sufficient supporting evidence that caching and not caching are alternative options. Further, there is sufficient evidence, in the context of the disclosures of written description support in the Provisional Application, providing support for Dr. Shenoy’s testimony that Patent Owner had possession of an edge server receiving an instruction to not cache the resource. Nonetheless, we invite additional briefing on these issues, including issues relating to alternative options of caching and not caching. On this preliminary record, we find that the ’573 patent has a priority date of April 2, 2008, which predates the earliest possible date on which Newton-471 could be effective as prior art, September 30, 2014 (the date on which the earliest application in the priority chain of Newton-471 was filed). Accordingly, we preliminarily find that Newton-471 is not prior art to the challenged claims. Thus, on the present record, Petitioner has not demonstrated a reasonable likelihood that it would prevail in showing that claims 1–20 are anticipated by Newton-471.” slip op. at 13

    “application must comply with the written description requirement of 35 U.S.C. § 112.” Zenon Envtl., Inc. v. U.S. Filter Corp., 506 F.3d 1370, 1378 (Fed. Cir. 2007) (quoting Lockwood v. Am.

To comply with the “written description” requirement of 35 U.S.C. § 112, first paragraph, an applicant must “convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention. The invention is, for purposes of the ‘written description’ inquiry, whatever is now claimed.” Vas-Cath, Inc. v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed. Cir. 1991) (emphasis omitted). The invention claimed does not have to be described in ipsis verbis to satisfy the written description requirement. Union Oil Co. v. Atlantic Richfield Co., 208 F.3d 989, 1000 (Fed. Cir. 2000). The question of written description support should not be confused, however, with the question of what would have been obvious to the artisan. Whether one skilled in the art would find the claimed invention obvious in view of the disclosure is not an issue in the “written description” inquiry. In re Barker, 559 F.2d 588, 593 (CCPA 1977). “A description which renders obvious the invention for which an earlier filing date is sought is not sufficient.” Lockwood, 107 F.3d at 1572.” slip op. at 11

Petitioner argues that “Beaumont does not describe a specific interface for manually entering [policy and rules] preferences, Hasan discloses a GUI for exactly this type of policy specification.” Id. at 14 (citing Ex. 1003 ¶ 70). Petitioner asserts that Hasan discloses that its Java-based, “platform independent” GUI takes the form of a “familiar tree structure” and allows administrators to “configure device and service configuration data and policy information.” Id. (citing Ex. 1006, code (57), 7:7–26, 8:19–29, 18:9–20). Petitioner asserts that the combination of Beaumont and Hasan would have been straightforward, and a person of skill “would have been motivated to incorporate Hasan’s GUI so that administrators could conveniently configure preferences for Beaumont’s DNS servers through an intuitive interface.” Id. (citing, inter alia, Ex. 1003 ¶¶ 70–71; Ex. 1007 ¶ 23). Patent Owner does not present any arguments on the rationale to combine. See generally Prelim. Resp.

  • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted

    “We agree with Patent Owner that its understanding of a policy as a rule is consistent with the disclosure in the ’517 patent that “a policy may be created by generating a decision tree representing the ATC rules.” See Ex. 1001, 9:1–3. We do not agree with Patent Owner, however, that Beaumont in combination with Hasan does not disclose the claimed policy features as claimed. As discussed above, Petitioner relies upon Beaumont in combination with Hasan with its teachings on the use of Java-based GUIs in the form of a tree structure that allows administrators to configure device and service configuration data, as well as policy information. See Ex. 1006, code (57), 7:7–26, 8:19–29. For the policy teachings, Petitioner relies upon Beaumont’s “content provider DNS server that directs requests (traffic) according to a preference table (policy).” Pet. 15–16 (citing Fig. 1, ¶¶ 6, 17, 23). Petitioner also asserts that the Beaumont-Hasan GUI would enable an administrator to set policies for a selected content delivery server to allow setting server preferences and rules. Id. at 17–18 (citing, inter alia, Ex. 1007 ¶¶ 76–77). In support, Dr. Lin testifies that: The Beaumont-Hasan GUI would enable an administrator to select a content delivery server (e.g., in Japan) and set policies for that server. Hasan, 8:30–36, 10:25–34, 10:53–67; Beaumont, [0031]. For example, given the description in Hasan, selecting a server would bring up a menu enabling an administrator to assign the preferences shown in Fig. 3 of Beaumont. Hasan, 10:25–34; Beaumont, Figs. 2, 3, [0029]–[0031]. A POSITA would thus have recognized the combined GUI to “support[] the setting of said at least one policy using a decision tree representing rules” because it is presented in a “familiar tree structure” and would allow users to set server preferences and rules. Ex. 1003 ¶ 77 (emphasis added). Beaumont provides support for Dr. Lin’s testimony. Beaumont discloses that “rules such as selecting one [a server] based on user preferences can be used . . . [f]or example, a preference number can be assigned to each content delivery server and a destination domain.” Ex. 1007 ¶ 31. Beaumont further states that “FIG. 3 shows an illustrative example of incorporating preference numbers in a column.” Id. Thus, contrary to Patent Owner’s arguments, Beaumont discloses that rules or policies, represented by the preference number, are represented in the table shown in Figure 3 of Beaumont. Dr. Lin also testifies that in the Beaumont-Hasan combination “the GUI supports the setting of” policy is taught. Ex. 1003 ¶ 77. Hasan provides support that service policies can be modified by the use of a GUI. See Ex. 1006, 8:30–36, 10:25–34, 10:53–67. Accordingly, in the combination of Beaumont and Hasan, wherein the preference database is replaced by the GUI decision tree, Petitioner has provided sufficient evidence at this juncture that the combination of Beaumont and Hasan teaches that the GUI obtains a policy, the preference number, for the direction of network traffic, where the GUI supports the setting of the policy using a decision tree representing rules.” slip op. at 19

    “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.

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

  • 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

    “Second, Patent Owner and Dr. Howell assert that a person of ordinary skill in the art “would have understood upon reading the second German application that the capsule features described would be intended to be combinable with each of the described embodiments.” PO Resp. 40; Ex. 2017 ¶ 61. But Patent Owner and Dr. Howell do not explain how a barcode could be used in the devices depicted in Figures 16–18, which place the detection means 2.4.2 on the outer circumference of the flange (not its underside) and rely on toothed-rings physically interacting with either the chamber, retaining arms, or a pinion. Ex. 1047, 12:22–31, 13:8–18. Indeed, the second German priority application explains that means 2.4.2 physically interacts with retaining arms 30 (embodiments of Figures 16 and 17) or a pinon (embodiment of Figure 18), and if means 2.4.2 were not present in these embodiments the capsule would either “drop through into a waste container” or could not be inserted through the insertion shaft. Id. at 12:22– 27, 13:9–12, 13:16–35 (noting that in the embodiment disclosed in Figure 18 a pinon interacts with means 2.4.2 and only when means 2.4.2 “is formed complementary to the teeth of the means” can the capsule be inserted). At no point does the second German application identify means 2.4.2 as a barcode or suggest a barcode could be used as the detection means. The second German application also states that A person skilled in the art is also aware that for example the insertion shaft may also contain a sensor, for example a camera, clear, however, that element 27 is part of the brewing chamber, and not the capsule. Ex. 1047, 12:27–31, 13:5–8, 13:21–26, 15:36. Thus, we are not persuaded that the toothed ring is in fact on the bottom side of the flange. which senses the shape of the means 2.4.2. For example, it would be possible, in the present case, for the shape of the teeth and/or the spacing between the same to be sensed. This signal, in turn, is passed to a control means, which frees, for example, the brewing chamber if the capsule is the correct one. Ex. 1047, 14:11–19. Again, despite using a camera to determine if a capsule is “the correct one,” the second German application does not suggest using a barcode in place of the toothed-ring structure, or suggest moving the location of the detection means 2.4.2 from the outer surface to the underside of the flange. This reinforces that the inventors did not contemplate using a barcode in the embodiments depicted in Figures 16–18.” slip op. at 23

    “As asserted by Petitioner, Jarisch teaches how to move a code in a centrifugal brewing system to the bottom of the flange and how to configure a light-conductive material so that the detector’s light source will reach the bottom of the flange. Pet. 48–49; Pet. Reply 23–24 (Ex. 1003 ¶¶ 184–185; Ex. 1005 ¶¶ 82–84, Fig. 5). And, although Figure 61 of Yoakim discloses a flare in its brewing chamber, bodily incorporation is not required, and we are directed to no persuasive argument or evidence that Yoakim could not be configured with a straight chamber, as generally depicted in Figure 5 of Jarisch. Pet. Reply 24 (noting that Dr. Howle’s testimony on this subject is “conclusory” and depends on “bodily incorporation”). As such, we credit the testimony of Mr. Jobin that a person of ordinary skill in the art would have sought to place the code at the bottom of the flange and would have had a reasonable expectation of success in so doing.17 Ex. 1003 ¶ 184. Patent Owner further contends that Yoakim requires that the capsule holder be capable of receiving a set of multiple volume capsules and that 17 As discussed above, Mr. Jobin has extensive experience in the design of brewing devices. Conversely, Dr. Howle has limited experience in this field and is not one of ordinary skill in the art. Although Mr. Jobin’s testimony is more persuasive regardless of the discrepancy in experience between the two declarants, when this difference in design experience is considered, it only serves to increase the weight we give to Mr. Jobin’s testimony. there is a “snug fit” to avoid “unbalances.” PO Sur-reply 8 (citing Ex. 1004 ¶¶ 205, 479, 484, 507, 512). According to Patent Owner, Petitioner does not explain adequately how the use of Jarisch’s “straight chamber” with a capsule holder that does not engage with the side wall of the capsule would allow insertion of the multiple volume capsules or permit a “snug fit.” Id.; PO Resp. 28. Patent Owner’s assertion that Yoakim discloses the use of certain capsules that might not fit into a device with Jarisch’s non-flared structure is ineffective to undercut the sufficiency of Petitioner’s showing on this point. As noted by Patent Owner, Yoakim discloses the use of certain capsules which might not fit into a device with Jarisch’s non-flared structure. But Petitioner is not seeking a bodily incorporation of Yoakim and Jarisch, and other embodiments of Yoakim do not require the type of flared capsule identified by Patent Owner. Ex. 1004, Fig. 63. Moreover, we are directed to no persuasive evidence that Jarisch’s lack of contact between the capsule side wall and the holder would render the device inoperable or even less effective. Id. (citing Ex. 2019, 36:18–37:6; Ex. 1005 ¶ 23 (Jarisch explaining that its device includes a capsule holding means and that the capsule may be successfully driven in rotation). As such, we credit the testimony of Mr. Jobin that one of ordinary skill in the art would have understood how to design the chamber of Yoakim to allow reading of a barcode on the underside of the flange and that this design would allow for successfully receiving single-serve capsules and driving them in rotation.

    “Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence.

See 35 U.S.C. § 314(a). Where unpatentability rests on a document that is prior art to a challenged patent but for that patent’s priority claim to an earlier effective filing date, such a priority claim is not presumed valid. PowerOasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1305 (Fed. Cir. 2008) (noting that the USPTO does not routinely determine whether such priority claims meet the requirements of 35 U.S.C. § 120).” slip op. at 5

    “Patent Owner has shown sufficient written description support for the claims, including the disputed “detecting” limitation. The “decode-to-learn- ‘D’” description in the specification of the ’146 patent and in the provisional application to which the ’146 patent claims priority describe a specific procedure for the claimed “detecting, from the received wireless packet, the second header field which repeats the first header field.”3 See Ex. 1001, 2 Petitioner specifically asserts that Huang qualifies under 35 U.S.C. §102(b). Pet. 2, 19 (“by more than a year”). However, Huang’s patent issuance date of April 28, 2020 does not qualify under § 102(b) because it is less than one year before the December 29, 2020 filing date of the ’146 patent. Nevertheless, Petitioner has made an effective showing that Sun would qualify as prior art sufficient to shift the burden of production to Patent Owner. 3 Patent Owner does not explicitly show support for each of the applications in the priority chain. Patent Owner also cites to a Pre-Grant Publication rather than the underlying application despite the fact that such a Publication may include amendments to the originally filed application that would not evidence written description. See 37 C.F.R. § 1.215 (a); MANUAL OF PATENT EXAMINING PROCEDURE §1121; Ex. 2003, 7 (showing amendments 3:1–11; Ex. 2001 ¶ 35; Ex. 1008, 5–6; PO Sur-Reply 6.

  Claims 1–4, 6–16, 18–24, 28, and 29 are unpatentable as anticipated by Chen-069, which is prior art because the 2012 application lacks written-description support for their full scope.

    “ordinary skill in the art at the time of the invention of the ’948 patent would have had “(i) a Bachelor’s degree in Physics, Optical Sciences, or equivalent education or training, as well as (ii) approximately three years of experience in designing multi-lens optical systems.” Id. at 12 (quoting Pet. 13–14 (citing Ex. 1003 ¶ 28)). We also found that “[l]ack of work experience could have been offset by additional education, and vice versa,” and that one of ordinary skill in the art “would have understood the fundamentals of optical aberration theory, and understood and used standard techniques for making lenses cheaper and more effective, especially for lens systems used in mobile devices.” Id. (quoting Pet. 14; Ex. 1003 ¶¶ 28, 30). We also agreed with Petitioner and found that one of ordinary skill in the art “would have known how to use lens design software such as Code V, Oslo, and ZEMAX, and would have taken a lens design course or had equivalent training.” Id. (quoting Pet. 14; Ex. 1003 ¶ 29). We also agreed with Petitioner and found that one of ordinary skill in the art “would have regularly used such software to create new lens designs, often using pre-existing lens designs as a starting point and then performing routine optimizations to reach a desired design.” Id. at 12–13 (quoting Pet. 14; Ex. 1003 ¶ 29). Patent Owner does not identify a level of skill in the art that one would have had at the time of the invention of the ’948 patent or identify any shortcoming in Petitioner’s formulation. See PO Resp. 16–17. Because Petitioner’s definition of the level of skill in the art is consistent with the ’948 patent and the asserted prior art, we maintain it for purposes of this Final Written Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC, 57 F.3d at 1579; In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).” slip op. at 8

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

    “Patent Owner argues that construing the challenged “claims to include first and second lens elements having the same refractive power . . . is improper.” PO Resp. 21. According to Patent Owner, one of ordinary skill in the art “would construe the [’]948 [p]atent claims to include first and second lens elements in the form of a ‘doublet,’ which requires the respective lens elements to have opposite refractive power, and thus includes only configurations” of “positive-negative” and “negative-positive” for the first and second lens elements, respectively. Id. at 20–21. In other words, “[t]he proper construction of the ’948 [p]atent claims is that the first and second lens elements may have positive-negative or negative-po[sitive] refractive powers, but would not include first and second lens elements having the same refractive polarity,” according to Patent Owner. Id. at 26. Thus, the parties agree that the challenged claims should be construed to encompass at least a lens system having a first lens element with a negative refractive power and a second lens element with a positive refractive power. See, e.g., Pet. 33; PO Resp. 21. We conclude that such a lens system is consistent with the plain language of the challenged claims. See, e.g., Ex. 1001, 12:8–26, 13:14–38, 14:16–46 (reciting first and second lens elements without reciting a specific refractive power polarity for the independent claims). And we determine that no claim terms require further construction in light of our findings below. See, e.g., Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)) (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’”).” slip op. at 10

    “In sum, we determine that the 2012 application does not provide written description support for an imaging lens system with a negative refractive power first lens and a positive refractive power second lens. And the agreed scope of the challenged claims includes such a configuration, and thus, the written description of the 2012 application does not support the full breadth of the challenged claims. We therefore determine that the challenged claims of the ʼ948 patent do not benefit from the priority date of the 2012 application. Therefore, we determine that Chen-069 is prior art to the challenged claims of the ʼ948 patent.” slip op. at 23
