    “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.

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. The Petition notes that Aspar transfers “thin layers of very good thickness homogeneity and with a high crystalline quality,” but the Petition never asserts that Lee’s direct deposition method fails to provide these same or similar qualities.

    “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

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.

At this time, Patent Owner does not dispute Petitioner’s proposed construction of “electrode section.” See generally Prelim. Resp.

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.

    “We interpret the term “heartbeat signals” as “periodic signals.” The term “heartbeat” appears only once in the in the specification outside of the claims: “the ‘heartbeats’ of the ping are set at a high rate, such as 100 or even 1000 per second.” Ex. 1001, 18:7–13. The disclosure of “the heartbeats” having a “rate” defined in “per second” terms indicates that they are periodic, as is generally recognized for heartbeats, i.e. human heartbeats. The term “heartbeat signals” appears in the challenged claims in conjunction with the detection of an anomaly (claim 12, “wherein the controller detects an anomaly in heartbeat signals from the remote unit”) and in conjunction with “skips” (claim 13, “wherein the anomaly includes skips of heartbeat signals”; claim 14, “when the anomaly includes a predetermined number of skips of the heartbeat signals”; claim 15, “when skips of the heartbeat signals are less than the predetermined number”). Accordingly, the heartbeat signals allow for the detection of an anomaly therein, indicating that they are typically predictable, and for the detection of skips of heartbeat signals, indicating that they are periodic. In view of the specification and the claims, and the parties’ arguments, we find that the plain and ordinary meaning of “heartbeat signals” is “periodic signals.”” slip op. at 12

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.

    “Turning to the disputed term “automatically” in this context, we agree with Patent Owner that the plain meaning of the term “automatically” is that the “control system” can, on its own and without human intervention, perform the subsequently recited step. Resp. 11–15; see also Pet. 10 (Petitioner agreeing this is the plain meaning). This is supported by the Specification, which states, inter alia, that “the entire system is controlled by the controller CPU” and describes alternative embodiments where (1) the system is fully in control and where (2) user input identifies targets. Ex. 1027, 12:23–25, 13:25–44, Figs. 14, 15. However, we also agree with Petitioner that just because the claimed “control system” is configured/programmed to perform (i.e., capable of performing) some tasks “automatically” (i.e., entirely on its own), this does not mean user input (e.g., from a surgeon) must be altogether excluded. Pet. 10–11. In fact, user input must be possible and is within the scope of the independent claim. “By definition, an independent claim is broader than a claim that depends from it, so if a dependent claim reads on a particular embodiment of the claimed invention, the corresponding independent claim must cover that embodiment as well.” Littelfuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed. Cir. 2022). Here claim 2, requiring automatic target identification, and claim 5, requiring user input on target identification, each depends from claim 1 and illuminates its scope, which must be broad enough to encompass both. Thus, although requiring (in claim 1) that a “control system” can perform certain recited functions, and that some are performed (according to claim 2) “automatically,” that same “control system” must also be capable of allowing a user input on the locations of targets for laser treatment (according to claim 5). Such optional user input required by dependent claim 5 is described in the Specification, which includes embodiments where a surgeon can adjust the size, location, and shape of the treatment pattern, can determine the optimal cutting contours in patients, and can provide “user input” to define targets or adjust computer-defined parameters as necessary. Ex. 1027, 10:55–45; 10:67–11:2, 13:25–55, 13:63–14:2. Regardless, the configuration of independent claim 1’s “control system,” which must be programmed to and capable of performing its own recited steps/functions, is not diminished by the requirements of either dependent claim.

Based on the record, we conclude that, even if it would have been potentially advantageous to in some way incorporate the use of Baikoff’s and Li’s OCT imaging and measuring into Swinger’s system and method for cataract surgery (for example, to replace the use of ultrasound imaging with OCT), we agree with Patent Owner that, other than the (ultimately) conclusory testimony of its witness Dr. Izatt (see, e.g., Ex. 1001 ¶¶ 110, 144, 151, 161, 163–165, 168), there is no persuasive evidence that the person of ordinary skill in the art would have combined these references with the result being a control system configured to (automatically or not in practice) image cataractous eye tissue, identify the targets therein (capsule and lens) to be cut with a laser, and then operate that laser to actually make those cuts based in some part on that imaging. See Resp. 15–34. We credit Dr. Kang’s testimony that, as of the invention, the person of ordinary skill in the art would not have relieved the surgeon of responsibility for identifying cutting regions for laser capsulotomy and cataract surgery (as taught by Swinger), and relegated such task to a computer, which subsequently performs the procedure.

Dr. Kang takes issue with Petitioner’s positions that Baikoff and Li teach or suggest such reliance on a computer because, according to Dr. Kang, neither Baikoff nor Li (and indisputably not Swinger) teaches using a computer to identify laser cutting regions or to control laser surgery, and, in fact, they suggest reliance on a surgeon to interpret their OCT images to plan a subsequent surgery. See, e.g., Ex. 2087 ¶¶ 36–38, 42, 46, 62–66. We further credit Dr. Kang’s testimony that Petitioner fails to adequately explain, even were the ordinarily skilled artisan intent on combining Baikoff’s and Li’s OCT imaging systems with Swinger’s cataract surgery system, how it would have been accomplished to overcome the “substantial challenges” and achieve the claimed invention.

They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
