Compare Pet. 9 with PO Resp. 14. On this record, we adopt Patent Owner’s proposed definition, as it is more consistent with the prior art of record and the disclosures of the ’702 patent.

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.

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.

    “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.

    “Petitioner’s proposed definition of the person of ordinary skill in the art appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosure of the ’725 patent; however, we also agree with Patent Owner that such a definition should be flexible enough to include a person with a lesser academic degree and having experience working in the field, such as an engineer with clinical experience in ophthalmic surgery, as well as also including a medical doctor, such as an ophthalmic surgeon with experience working with medical optics and lasers, and that these people may collaborate. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

    “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.

PO Resp. 18–23. Petitioner relies on Li for this limitation, however, while Li discloses the use of OCT imaging to measure certain dimensions of the anterior chamber of the eye, Li suggests that a person of ordinary skill in the art manually use the measurement data collected by the system. (Ex. 1044, 1; Ex. 2087 ¶¶ 44–46). More specifically, as summarized by Patent Owner: Li does not suggest configuring the control system to do anything at all with the measurements that it makes, much less determine an anterior capsulotomy scanning pattern. Kang [Ex. 2087] ¶¶ 80, 128. To the contrary, Li’s suggestion of using measurements to “improve the fitting of AC-IOL” teaches a [skilled artisan] to manually use the measurement data. Id. Dr. Izatt testified that “in Li, the controller, so to speak, is a human.” Ex. 2057, 207:17–208:7; see also id., 207:20–21 (in Li, “the one who identifies the treatment region is the surgeon”).

    “The problem with Petitioner’s argument based on Leapfrog and the like is that Petitioner’s obviousness challenge does not simply require automating a manual step using commonplace modern electronics, but requires the conversion of one cataract surgery treatment region identification system into another. That conversion involves the incorporation of OCT imaging technology as the basis for a computer-controlled system to plan and implement eye surgery, two technological leaps that the record fails to show was 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 implement cataract surgery in the lens was commonplace. We recognize that Petitioner directs us to the testimony of Dr. Izatt who opines that a person of ordinary skill in the art would have found it obvious to, for example, use a controller to determine the claimed scanning pattern. Pet. 32–33; Reply 3–5; see also Ex. 1123 ¶ 31 (“Once the anterior capsule is identified, it is a relatively simple process to determine the location to place the capsulotomy.”). Here, however, we agree with Patent Owner that the Petition and supporting testimony fails to provide the requisite reasoned analysis with sufficient evidence to support Petitioner’s position on obviousness. In particular, absent some evidentiary support beyond Dr. Izatt’s and Dr. Tipperman’s opinions that it would have been obvious to program a controller to bridge the gap between the functionality disclosed in Swinger and the required functionality of the challenged claims, we are unwilling to accept this line of reasoning.

See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Such an expanded definition of the person of ordinary skill in the art, including aspects of both parties’ definitions, is appropriate here, based on our review of the record. Thus, we find that the person of ordinary skill in the art would have been someone with a PhD, MS, or BS degree in physics, biomedical engineering, or a related science such as nuclear engineering, having more or less experience in research, manufacturing, or designing medical optics or medical lasers (e.g., 5 years for a PhD or more to compensate for lesser degrees), or an ophthalmic surgeon, but 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).

Cir. 2016). “The reasonable expectation of success requirement refers to the likelihood of success in combining references to meet the limitations of the claimed invention.” Id. at 1367. The evidence of record suggests that the ordinarily skilled artisan would not have had a reasonable expectation of success in achieving the claimed invention based solely on Swinger’s, Baikoff’s, and Li’s teachings. Further, as our reviewing court has explained, “references to ‘common sense’—” or an ordinarily skilled artisan’s ordinary creativity, “whether to supply a motivation to combine or a missing limitation—cannot be used as a wholesale substitute for reasoned analysis and evidentiary support, especially when dealing with a limitation missing from the prior art references specified.” DSS Tech.

In particular, Dr. Cossairt’s testimony is supported by the following discussion in Hutchison: To calculate an average molecular formula for 1 it is necessary to know the number of gold atoms in the metal core. Given the average particle size (1.5 nm) this number is estimated to be ~101 by the method of Whetten et al. and leads to an estimated formula of Au101(PPh3)21Cl5. Ex. 2017, 12891.

In Petitioner’s view, an ordinarily skilled artisan would have had “at least a Ph.D. in chemistry, physics, chemical engineering, material science, or equivalent technical degree or equivalent work experience, with knowledge regarding nanoparticles and methods of synthesizing them” and “[a]dditional education might supplement practical experience and vice-versa.” Pet. 22 (citing Ex. 1002 ¶ 76). Patent Owner does not address Petitioner’s view or propose a counter definition. We determine that the level of ordinary skill is reflected in the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (specific findings on the ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985))). To the extent a more specific definition is required, we adopt Petitioner’s definition for purposes of this Decision, because that definition is unopposed and consistent with the disclosures of the asserted prior art references.” slip op. at 9

    “Based on our consideration of the record as a whole, we agree with the District Court that the molecular cluster compound of the claimed invention must have “sufficiently well-defined chemical structure such that all molecules of the cluster compound possess the same relative molecular formula.” Ex. 1091, 18. To the extent that this or any other claim term requires further discussion, we provide it in our analysis of the challenges. No further express claim construction is necessary for purposes of this Decision. See Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (“[C]laim terms need only be construed ‘to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))).” slip op. at 11

    “opinion, with supporting citations to evidence, that Banin describes gold clusters that range in size and, further, why the reference indicates that the suggested formula assigned to those clusters is based on a calculation that relies on the average of a wide distribution of particle sizes reported in the literature by Hutchison. Ex. 2030 ¶¶ 102–125; Ex. 2017, 12891. We assign persuasive weight to her testimony because it is supported by clear disclosures in Hutchison, which Banin explicitly identifies as the source of the procedures by which Banin synthesizes its gold clusters. In particular, Dr. Cossairt’s testimony comports with this discussion in Hutchison: To calculate an average molecular formula for [gold nanoparticle] 1 it is necessary to know the number of gold atoms in the metal core. Given the average particle size (1.5 nm) this number is estimated to be ~101 by the method of Whetten et al. and leads to an estimated formula of Au101(PPh3)21Cl5. Ex. 2017, 12891. In other words, as this disclosure makes plain, Hutchison calculates an average molecular formula for its gold clusters by estimating the number of gold atoms in the metal core based upon the average particle size of 1.5 nm. Id. Indeed, as Dr. Cossairt recognizes, Banin’s suggested molecular formula is exactly the same formula that Hutchison calculates based on the average molecular formula for the variably-sized gold clusters produced according to its process. Ex. 2030 ¶¶ 102–105. Dr. Cossairt provides persuasive reasons why a person of ordinary skill in the art would have understood that Banin’s suggested formula represents an average molecular formula for a disperse mixture of gold clusters that are not identical in size and do not have sufficiently well-defined chemical structure such that all molecules of the cluster compound possess the same relative molecular formula, as required for MCCs. Id. ¶¶ 102–125.” slip op. at 26

  • Strike new argumentNew argument disregardedDecided for patent owner

    “Our rules require a petitioner to explain with particularity, at the outset in the petition, why the patent it challenges is unpatentable. Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016). “Unlike district court litigation — where parties have greater freedom to revise and develop their arguments over time and in response to newly discovered material — the expedited nature of” inter partes review proceedings “bring with it an obligation for petitioners to make their case in their petition to institute.” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369 (Fed. Cir. 2016). Accordingly, Petitioner carries a burden to “identify with particularity” at the outset, in the Petition, “the grounds on which the challenged to each claim is based, and the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3). Although “the introduction of new evidence in the course of the trial is to be expected in inter partes review trial proceedings,” Genzyme Therapeutic Prods. LP v. Biomarin Pharm. Inc., 825 F.3d 1360, 1366 (Fed. Cir. 2016), the shifting of arguments is not, Wasica Fin. GmbH v. Cont’l Auto. Sys., Inc., 853 F.3d 1272, 1286 (Fed. Cir. 2017).” slip op. at 30
