      “1996) (“It is well-settled that, in interpreting an asserted claim, the court should look first to the intrinsic evidence of record, i.e., the patent itself, including the claims, the specification and, if in evidence, the prosecution history.”). Upon review of the parties’ arguments and the intrinsic record, we agree with Petitioner that the ’702 patent does not support a construction of “stackable add-on layer” that encompasses memory cells formed by sequential deposition on a substrate without being formed and then added to a separately formed substrate. Pet. 11–12. First, the plain language of the claim does not require merely a “layer” having a plurality of vertically oriented semiconductor memory cells, but rather “a stackable add-on layer” having a plurality of vertically oriented semiconductor memory cells; that plurality is bonded to the dielectric layer. Ex. 1001, 12:29–32. A construction that gives meaning to all words of the claim is preferred. Merck & Co., Inc. v. Teva Pharm. USA, Inc., 395 F.3d 1364, 1372 (Fed.

      “As discussed above, we do not understand a “stackable add-on layer” to include memory cells that are formed by sequential deposition on or above a substrate without being added to a separately formed substrate. It is undisputed, and indeed it is Petitioner’s assertion, that Lee’s memory devices are formed by sequential deposition. Pet. 16, 29 n.11, 51 (“In Lee, each level 3104 is deposited on the underlying level of array 3101.”). Therefore, Petitioner has not shown that Lee discloses every limitation of independent claim 13 under our claim construction. Thus, Petitioner does not demonstrate by a preponderance of the evidence that claim 13 would have been obvious in view of Lee. 3. Analysis: Claims 14–17 Claims 14–17 each depend, directly or indirectly, from claim 13. Petitioner’s arguments with respect to these claims do not remedy the deficiencies noted above with respect to claim 13. Pet. 31–41.

      “We agree with Patent Owner that Petitioner has not demonstrated that Aspar would improve Lee, would solve a problem in Lee, and that Petitioner is proposing to use Aspar in a way that is not disclosed in the reference. PO Resp. 49–50 (citing Ex. 2029 ¶¶ 153–162); Tr. 57:24–58:12; Pet. 61; KSR, 550 U.S. at 417 (asking whether a technique “would improve similar devices in the same way”), 420 (asking whether there was a known problem in the art), 421 (asking whether one of ordinary skill in the art had reason to “pursue the known options”); Intel, 61 F.4th at 1381 (explaining that obviousness may be demonstrated by showing that there was a known problem in the art (“cache coherency in multiprocessor systems”) and that a person of ordinary skill in the art would recognize that that the prior art solution to this problem (“global segmented secondary cache”) would improve the system of another prior art reference). Petitioner does not persuasively show that there was any known problem in the art with respect to Lee or its monolithic method of constructing memory arrays. Nor does Petitioner provide persuasive argument or evidence that Aspar’s wafer bonding would improve Lee’s memory device.10 For example, Petitioner states in a conclusory fashion that Aspar would address the known problem of “fabricating 3D structures,” but does not explain what those problems were or why Lee fails to solve them. Pet. 61. Dr. Sechen’s testimony merely parrots the Petition, providing no further analysis or explanation of what problem might exist in Lee when fabricating its 3D structures. Ex. 1003 ¶ 212.

      “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

      “The definiteness requirement of § 112(a) is satisfied when “a patent’s claims, viewed in light of the specification and prosecution history, inform those skilled in the art about the scope of the invention with reasonable clarity.” Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898, 910 (2014); see 37 C.F.R. § 42.100(b) (changing the claim construction standard used to review a claim proposed in a motion to amend from the broadest reasonable construction to the “same construction standard that would be used to construe the claim in a civil action under 35 U.S.C. [§] 282(b)”). Proposed substitute claim 104 generically requires “in situ precipitate” and also a specific type of in situ precipitate: “in situ galvanically-active intermetallic precipitate.” Mot. Appendix A. 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. Mot. Reply 4. As such, we do not find that this part of proposed substitute claim renders claim 104 indefinite.” slip op. at 22

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “We determine Patent Owner’s reading of the claim limitation is the better one. The limitation begins with the verb “locating,” and it therefore makes sense that the clause would recite what is located (i.e., encryption information) and where it is located (i.e., within the requested portions of the selected stream of protected video). In other words, it is reasonable that the second and third clauses of the limitation both modify the first clause (for example, as could perhaps be expressed through the use of commas as “locating encryption information, that identifies encrypted portions of frames of video, within the requested portions of the selected stream of protected video”).10 On the other hand, Petitioner’s reading of the limitation, 10 In general, we recognize that the use of commas to set off phrases in claim drafting is not consistent. We included commas above to illustrate Patent Owner’s understanding of the claim limitation. allowing only the second clause to modify the first, while not unreasonable, makes less sense. That is, the encrypted information identifies the encrypted portions of frames, which in turn are within the requested portions of the selected stream of protected video. Reading the claim in its entirety, the encrypted portions of frames would be understood to be located within the requested portions of the stream; it does not seem necessary for the claim to expressly recite that aspect. For example, the very next limitation— limitation [m] of claim 1—refers to “each encrypted portion of the frames of video” but does not expressly recite “within the requested portions of the selected stream.” Ex. 1001, 27:58–60. Thus, when limitation [l] recites “within the requested portions of the selected stream,” it seems more likely that the clause refers to where that encrypted information is located rather than simply to indicate the obvious location of the encrypted portion of the frames of video. We therefore view Patent Owner’s reading of the claim language as the better one.” slip op. at 13

I also agree that Patent Owner’s arguments attempt to recharacterize limitations [j] and [k] to raise issues that Patent Owner did not raise previously, in contravention of our Order that issues raised needed support from “where those issues were raised in previous briefings by the parties.” Paper 56, 2. I have addressed whether scalability and FEC are integral to how Chen operates above, as well as whether the Petition relies on those aspects, supra. The questions about how Chen operates and what portions of Chen are asserted in the ground of unpatentability were previously raised, but now are being considered or reconsidered, based on the Federal Circuit’s decision. In Patent Owner’s Remand Brief, pages 1–7, the citations to argument previously raised do not support the arguments now presented by Patent Owner on remand.

See PO Remand Br. 1 (citing PO Resp. 24–37 (the construction of “locating encrypted information . . . within requested portions”), 38–58 (referring to Patent Owner’s “common keys” argument)). 8 The Final Decision also addressed Petitioner’s Motion to Exclude (Paper 42). See Final Dec. 28–37 (granting-in-part, denying-in-part, and dismissing-in-part Petitioner’s Motion). Our determinations on that Motion were part of Petitioner’s appeal to the Federal Circuit.

Because the Federal Circuit did not address this aspect of the Final Written Decision and the Federal Circuit’s decision does not impact our previous rulings on the Motion, we maintain those rulings here. Additionally, on remand, Petitioner requested authorization to file a motion for sanctions, which we held in abeyance until the parties’ briefing on remand was complete. See Ex. 3003, 1.

      “Dr. Ducharme’s testimony that “the spacing of the chips in Zhang would not likely be so close as to create overheating issues” (Ex. 2002 ¶ 111) is unsupported by any disclosure of the actual spacing of Zhang’s chips. Consequently, his testimony that there would be no overheating concerns in Zhang due to the spacing of the chips is entitled to little, if any, weight. Dr. Ducharme further testifies that the components of Zhang’s driver “could easily increase the temperature of the LED 19 chips on the circuit board, which can cause LEDs to generate less illumination, burn out and otherwise adversely affect their performance.” Ex. 2002 ¶ 126. Dr. Ducharme further testifies that “[i]t is well-known that excessive operational temperatures can reduce the illumination provided by the LEDs, can decrease the operational lifetime of the LEDs, and if the temperature is sufficiently high, it can cause LED junction failure and a burnt-out LED.” Id. We agree with this testimony, which as discussed below, is consistent with Salam. Dr. Ducharme’s testimony concerning overheating issues caused by the driver components contradicts Patent Owner’s ’s contention that there would not be “an overheating issue with Zhang’s LED exit sign circuit in Figure 2.1.” PO Resp. 30. Regardless of whether Zhang’s LEDs in Figure 2.1 have a heat problem or not, Salam teaches the advantages of using a heat sink. Salam teaches that a heat sink will result in a higher efficiency of the LEDs and improved life. Ex. 1006, 16:38–43. The Federal Circuit, in DyStar Textilfarben GmBH & Co v. C.H. Patrick Co., 464 F.3d 1356 (Fed. Cir. 2006), stated that “the desire to enhance commercial opportunities by improving a product or process is universal–and even common-sensical . . . the proper question is whether the ordinary artisan possesses the knowledge and skills rendering him capable of combining the prior art references.” Id. at 1368.

Dr. Ducharme’s testimony is consistent with Petitioner’s contention that the combination of Zhang and Salam “would have been a straightforward combination of known components and technologies, according to known methods, to produce the predictable result of reducing/ mitigating heat effects in a circuit.” Pet. 17 (citing Ex. 1002 ¶ 106). Patent Owner next contends it would be extremely burdensome and costly to modify Zhang to add a heat sink layer because “each of the multiple chips mounted and epoxied to Zhang’s circuit board in the exit sign would have to be modified.” PO Resp. 30 (citing Ex. 2002 ¶ 112). Dr. Ducharme’s testimony repeats the Patent Owner Response verbatim and is entitled to little, if any, weight. Ex. 2002 ¶ 112.

    • Patent Eligibility (§101) › Alice/Mayo step one — 'directed to'IneligibleUnpatentable

      “3. Analysis On the full record developed during trial, we are persuaded by Patent Owner’s argument. Petitioner’s analysis of the independent claims described above only loosely corresponds to the actual limitations recited in the claim. The Federal Circuit has “cautioned that courts ‘must be careful to avoid oversimplifying the claims’ by looking at them generally and failing to account for the specific requirements of the claims.” McRO, Inc. v. Bandai Namco Games America Inc., 837 F.3d 1299, 1313 (Fed. Cir. 2016) (quoting In re TLI Commc’ns LLC Patent Litig., 823 F.3d 607, 611 (Fed. Cir. 2016)). Petitioner’s analysis of the claim limitations appears to do. Petitioner’s argument that “the essence of all the claims” is captured by a single claim element (f3) not only ignores that that limitation recites performing two specific software tasks simultaneously—which we are not persuaded is an abstract idea—but also asks us to disregard multiple technical aspects recited in the claims, such as identifying a link, determining whether an installation client is available on the device, invoking the installation client, and redirecting to the device an app store. See, e.g., Ex. 1001, 21:6–35. That is, under Step 2A of the Guidance, we are neither persuaded that limitation f3, which Petitioner points us to, recites an abstract idea (Prong 1), nor that the other limitations recited in the independent claims fail to integrate the alleged abstract idea into a practical application (Prong 2). Petitioner characterizes the claims as directed to multitasking, which Petitioner describes as representing a basic task in organizing human activity. Pet. 30. Although the Guidance recognizes certain methods of organizing human activity, including certain activity between a person and a computer, as constituting a patent-ineligible abstract idea, we are not persuaded that the claims here fall within the scope of such activity. See Guidance, 84 Fed. Reg. at 52 (listing fundamental economic principles or practices, commercial or legal interactions, and managing personal behavior or relationships as organizing human activity); October 2019 Update at 5 (“this grouping is limited to activity that falls within the enumerated sub-groupings . . . , and is not to be expanded beyond these enumerated sub-groupings except in rare circumstances”). The claimed invention may result in multitasking on the device, but the claims are directed to downloading and installing an application in the background instead of directing the user to an application, and do not recite an abstract idea. And although that process does result in improving user experience, the claims recite more than that mere result; they recite specific steps—invoking, without exiting the foreground software application, the installation client for downloading and installing applications on the device to run in the background—that accomplish the desired result. See Finjan, Inc. v. Blue Coat Sys., Inc., 879 F.3d 1299, 1305–06 (Fed. Cir. 2018) (finding a method that employs a new kind of file in a computer security system directed to a non-abstract improvement in computer functionality, rather than the abstract idea of computer security writ large). Petitioner thus fails to establish sufficiently that the claims are directed patent ineligible subject matter under Step 2A of the Guidance. We also agree with Patent Owner that the challenged claims are somewhat similar to those that the Federal Circuit held patentable in DDR Holdings. The claims there were directed to a method of generating a composite webpage that combined visual elements of a host website with content from a third-party, e.g., by combining the logo, background color, and fonts of the host website with product information from a merchant. DDR Holdings, 773 F.3d at 1248. When a user clicked on a link on the host website, the system would construct the composite web page comprising a look and feel description from the host website along with content based on product information from the merchant’s product catalog. Id. at 1250. The court held those claims were not directed at an abstract idea because they addressed the problem of retaining website visitors that, absent the claimed invention, would be instantly transported away from a host’s website after clicking on an advertisement and activating a hyperlink. Id. at 1257.” slip op. at 29

      “The parties present compelling argument and evidence that one of ordinary skill in the art would include those with experience in ophthalmology, as well as in the research, manufacture, and design of medical optics or medical lasers. Pet. 25; PO Resp. 9–10. The evidence of record also demonstrates that few individuals actually had such comprehensive experience. Rather, teams of individuals with different expertise and various academic degrees (Ph.D.s, B.S.s, and M.D.s) would work together to design laser surgery systems intended to make incisions in the lens of the eye. See, e.g., Ex. 1041 (several authors are M.D.s); Ex. 1042 (the authors’ degrees include Ph.D.s, an M.D., and a B.S.); see also Ex. 1053; Ex. 1054; Ex. 1055; Ex. 2010; Ex. 2019. Thus, we find that the person of ordinary skill in the art would have been either an ophthalmic surgeon or someone with a Ph.D., M.S., or B.S. degree in physics, biomedical engineering, or a related science such as nuclear engineering, having experience in researching, manufacturing, or designing medical optics or medical lasers (e.g., five years of experience for a Ph.D. or more to compensate for lesser degrees), and that such persons would have worked in collaboration with one another to fill any necessary gaps in knowledge (e.g., the engineer would consult the medical doctor on clinical issues or physiology and the medical doctor would consult the engineer on technical issues). This definition marries the two proposed by the parties.” slip op. at 11

      “summarized above, we find that the evidence of record does not support a conclusion that it would have been simple, straightforward, or otherwise routine to convert Swinger’s manual HeNe aiming system and Swinger’s surgeon-identification-of-target-tissue step to a computer-controlled, OCT-guided laser system. Even assuming that a person of ordinary skill in the art would have combined the teachings of Swinger and Baikoff to achieve a laser surgical system incorporating an OCT imaging system, that combination still would not have achieved the required “computer system” of the claims and all of its programmed surgical functionality, particularly, using a computer system to construct an anterior capsulotomy cutting region based on the image data. Petitioner relies on the ability of a person of ordinary skill in the art to configure Swinger’s computer control unit with the missing functionality, thus necessitating an electronic conversion of the steps performed using Swinger’s direct visualization method using a HeNe aiming beam to manually identify a surgical treatment region for laser surgery. Ex. 1039, 34:52–57; Ex. 2088 ¶¶ 55–59, 66. That conversion, however, involves the incorporation of OCT imaging technology as the basis for a computer-controlled system to plan and then implement the planned cataract surgery, two technological leaps that the record fails to show were known or suggested. In particular, the evidence of record does not support a conclusion that OCT was a well-known system used routinely, if at all, in the identification of treatment regions in the lens or lens capsule for cataract surgery, and further does not support a conclusion that a computer-controlled system to plan and to implement a planned cataract surgery in the lens was commonplace or even considered before the invention.” slip op. at 25

      “The evidence of record demonstrates, however, that modifying an existing corneal surgery system to image and perform surgery on the lens was not the simple task asserted by Petitioner. For example, in a patent application filed in November 2009, Petitioner asserted that due to the different depth ranges for the laser’s focus, “laser systems designed for corneal procedures do not offer solution[s] for the considerable challenges of performing surgery on the lens of the eye.” Ex. 2007, 4:65–67, 5:30–36, code (22). Similarly, in a different patent filed in December 2008, Petitioner outlined the various challenges in developing laser surgery systems for creating incisions in the lens, including the difficulty in focusing a laser beam that propagates through regions of the eye with different optical properties and different curvatures. Ex. 2014, 15:51–16:18, code (22). This patent then states: Because of all the described hard challenges, corneal surgical laser systems are qualitatively simpler than lens surgical lasers. This is well supported by the fact that even though corneal surgical systems were suggested about 40 years ago, none have been adapted successfully for lens surgery to date. Id. at 16:13–18. During prosecution of another patent filed in 2008, and in responses to office actions filed in 2012 and 2013, Petitioner argued that a corneal OCT system “simply will not work” on the lens and that it would not have been obvious to modify such an OCT system to image the lens. Ex. 2015, 898, 1591, 1788. This was because OCT systems designed to image the lens would be required to deliver and scan an imaging beam “to a depth ten times bigger and a depth range ten times bigger” than an OCT system designed to image the cornea. Id. at 1591. According to Petitioner, “it is not obvious” to modify an OCT imaging system to achieve a depth and scanning range that is ten times larger than that disclosed in the art.
