    “Petitioner contends: A person of ordinary skill in the art (“POSA”) at the time of the alleged invention of the ’223 patent would have had a university degree in chemistry and additional expertise or a second university degree in the field of electrical engineering, particularly optoelectronics, or alternatively a university degree in electrical engineering and additional expertise or a second university degree in the field of chemistry. The person of ordinary skill in the art has spent several years studying the structure and function of organic optoelectronic components, in particular OLEDs, and has detailed knowledge of the chemical structure of light-emitting organic layers and the transport of charge carriers to these layers. In this respect, the person of ordinary skill in the art works at the interface between electrical engineering/physics (charge carrier transport and light emission processes in optoelectronic components) and chemistry, in particular organic chemistry (materials and layer stack combinations suitable).

    “Based on the information presented, we find Petitioner has the better position. Patent Owner admits that joint vaporization means “two materials vaporize together.” Reply 21 (quoting Resp. 54). As Petitioner argues, “This is what Ma discloses.” Id. We agree with Petitioner that Ma describes a “two-component” electron transport layer having a “thickness with one value.” Id.; see Ex. 1007, 811 (reporting a “co-deposited” application of “BPhen:LiQ” that is “50 nm thick”). Ma’s disclosure, thereby, strongly “indicates that the two components were vaporized together––as opposed to creating a ‘macroscopically homogenous form’” prepared by sequentially vaporizing the individual components as Patent Owner “hypothesizes.” Reply 21 (citing Ex. 1020 ¶¶ 42–44; Ex. 2041 ¶¶ 155–157); see Resp. 54– 55; see also Ex. 1007, 811 (Ma’s description of its device fabrication, appearing in the third paragraph of the experiments section). Petitioner further advances evidence that “[p]reparing a layer that is ‘macroscopically homogeneous’ but potentially microscopically heterogeneous,” as Patent Owner postulates, “would introduce excessive variability and render the data noncomparable and unreliable, thus undermining the experiment’s purpose.” Reply 21 (citing Ex. 1020 ¶ 44); see Resp. 54–55. Patent Owner presents no counterargument or evidence that is persuasive to undercut Petitioner’s reasoning or evidence on that point. See Sur-reply 19–22. Petitioner also argues that an ordinarily skilled artisan would have recognized “that vaporizing materials together would best achieve Ma’s objective of assessing the current density using different Liq doping percentages.” Reply 22 (citing Ex. 1007, 811; Ex. 1020 ¶ 51). Here again, Petitioner’s evidence on point stands uncontested. See Sur-reply 19–22 (declining to contest that point). On this record, therefore, we agree with Petitioner that, as to the relevant disclosure in Ma, “the most natural interpretation of ‘co-deposition’ for forming a layer, particularly when there is nothing to indicate that the materials” are “vaporized sequentially,” is that the materials are co-deposited by joint vaporization. Reply 22 (citing Ex. 1020 ¶ 46–51). We further agree that, “[u]nder a preponderance standard, Ma’s disclosures are sufficient to render joint vaporization at least obvious.” Id. For the above reasons, we determine that Petitioner demonstrates by a preponderance of the evidence that Ma discloses joint vaporization as required by the challenged claims.” slip op. at 15

    “For purposes of this Decision, we adopt Petitioner’s definition of a POSITA. Petitioner’s witness (Mr. Cook) qualifies as a POSITA under this definition, and, therefore, is qualified to opine from the perspective of a POSITA on technical matters included within the areas of expertise prescribed by the definition. As indicated above, Petitioner’s definition of a POSITA does not require education in the field of optics and professional experience designing or analyzing optical apparatus, unlike Patent Owner’s definition. We are aware, however, that Patent Owner’s witness (Dr. Klopp) has more extensive experience with optical systems and methods than Petitioner’s witness (Mr. Cook).

Petitioner’s assertions that this would be the case consist solely of conclusory statements, supported only by citations to Mr. Cook’s declaration. Mr. Cook, however, simply repeats Petitioner’s conclusory statements, without providing sound technical reasoning supported by objective evidence to explain and support his opinions. Ex. 2003 ¶¶ 101– 102, 105, 195–198, 202.

As discussed above, Mr. Cook is qualified to opine from the perspective of a POSITA on technical matters included within the expertise of a person meeting Petitioner’s definition of a POSITA, which do not include optics and optical apparatus. We, therefore, credit Dr. Klopp’s opinion over that of Mr. Cook on this particular factual issue of how it is directly related to optical systems and methods about which Mr. Cook possesses limited relevant experience.

    “Based on the arguments and evidence, we disagree with Petitioner’s proposed construction requiring the corners to be rounded via a particular process, because doing so would improperly import a process of manufacture from the Specification into apparatus claims. See Cont’l Circuits LLC v. Intel Corp., 915 F.3d 788, 799 (Fed. Cir. 2019) (explaining that, generally, a novel product that meets the criteria of patentability is not limited to the process by which it was made, however, process steps can be treated as part of a product claim if the patentee has made clear that the process steps are an essential part of the claimed invention). Here, the portions of the Specification relied on by Petitioner (Ex. 1001, 2:10–20, 4:53–64) disclose a process for manufacturing but do not make clear that the process is an essential part of the claimed invention. We also disagree with Petitioner’s assessment of the prosecution history, i.e., that the claims were amended to distinguish the claimed rounded corners from Pfirsch’s rounded corners, which, presumably, are formed as an incidental result of lithography. On the contrary, the Examiner found (and Patent Owner acknowledged) that Pfirsch has rounded corners. Ex. 1002, 276, 295, 302. As Patent Owner correctly points out, the claims were amended during prosecution to include a “circular” contact to distinguish over Pfirsch’s square contact. See id.

    “is ‘known’ is not sufficient for a motivation to combine.” PO Resp. 47. However, the motivation-to-combine analysis is a flexible one, and the “known-technique” rationale is adequate to show a motivation to combine. For example, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417; see also Intel Corp. v.

Here, as discussed above, the record shows that top view rounding was a known technique to eliminate corners, and that corners were a known problem (e.g., corners tend to reach undesirable higher peak electric field leading to premature breakdown voltage). See, e.g., Ex. 1003 ¶¶ 37, 39, 42– 44, 55–57, 122, 133, 135–141; Ex. 1005, 7:57–8:4; Ex. 1006, 1:18–21, 2:19–39, 5:3–17, Figs. 6A–8B; Ex. 1011, 1:29–41; Ex. 1012; PO Resp. 13, 46 (citing Ex. 1011, 1:34–40); Ex. 2021 ¶ 87.

    “We agree that Kobayashi’ s Figure 5A solely cannot be relied upon as disclosing the claimed diameter. See Hockerson-Halbertstadt, Inc. v. Avia Group Int'l, 222 F.3d 951, 956 (Fed. Cir. 2000) (patent drawings not designated as being drawn to scale cannot be relied upon to define precise proportions of elements if the specification is completely silent on the issue). However, we do not agree that Petitioner failed to show Kobayashi suggests the recited diameter. We disagree with Patent Owner’s assertion that Dr. Liu’s “vague, purported ‘design considerations’” are “unsupported.” PO Resp. 43. Although Kobayashi is silent on the width/diameter of the trench contact in Figure 5A, Kobayashi discloses trenched gates having dimensions below 0.5 μm, which demonstrates that it was known in the art, and required no more than an exercise of ordinary skill in the art, to create trenched features of widths well below 1 μm. Kobayashi also discloses that the width of each trench, and the distance between the adjacent trenches (which includes the trench contact), must be selected to optimum sizes . . . [and] these sizes . . . have some degrees of freedom.” Ex. 1005, 7:42–48. This demonstrates a POSITA would seek to optimize trench contact width or diameter. Dr. Liu’s testimony regarding design considerations suggests the desirability of a reduced diameter trench contact, e.g., to minimize the width of the trench contact for purposes of easier filling, to minimize the total width of the unit cell, and to minimize manufacturing time by reducing etch back time. See Ex. 1003 ¶¶ 111–114. As Patent Owner acknowledges, “there is always a motivation to speed up the fabrication process or shrink feature sizes of semiconductors.” PO Resp. 43 (citing 2021 ¶ 131). However, contrary to Patent Owner’s arguments, these are not generic motivations “untethered” from Kobayashi. Id. Indeed, Kobayashi directly addresses the fabrication process (including new techniques to obtain trench widths under 0.5 μm) and the need to optimize the size of trench gates and the space in between (which includes the trench contact). Ex. 1005, 7:43–54, 7:19–9:53. Patent Owner also argues that Petitioner presents no evidence that modifying Kobayashi to have a diameter smaller than 1 μm is predictable. PO Resp. 44. We disagree. As discussed above, Petitioner points to Kobayashi’s teachings that the sizes are to be optimized and that the trench gate width is smaller than 0.5 μm, which suggests making other trench features of that width was within ordinary skill. Ex. 1003 ¶ 112. Furthermore, Kobayashi’s silence as to the dimensions of the trench contact suggests that the trench contact diameter dimension is likely in the ballpark of the other explicitly disclosed trenched feature dimensions and is a matter of routine optimization. In addition, Patent Owner advances no persuasive evidence that the claimed diameter produces unexpected results or is otherwise critical. Patent Owner also argues that reducing trench contact diameter has downsides (i.e., reduced ease of filling for metal plugs and reduced current carrying capacity) not addressed by Petitioner; however, Petitioner is not required to address those tradeoffs in its Petition, and we do not see how those tradeoffs would prevent the proposed combination. PO Resp. 44; see Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (“a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.”); Winner Int'l Royalty Corp. v.

Instead, the benefits, both lost and gained, should be weighed against one another.”). Here, Dr. Liu listed numerous benefits of having a reduced diameter, which weigh against the potential downsides raised by Patent Owner. Ex. 1003 ¶¶ 111–114.

The Federal Circuit has rejected this argument, holding that: a published patent application is, by its literal terms, a “printed publication.” So, when § 311(b) permits IPR challenges based upon “prior art . . . printed publications,” it includes within its literal scope challenges based upon a published patent application. And, by virtue of § 102(e)(1), a published patent application—this specific type of “printed publication”—is deemed prior art as of its filing date.

    “III. ANALYSIS A. Level of Skill in the Art Petitioner, relying on the testimony of Mr. Williams, contends that a person of ordinary skill in the art “would have had at least a bachelor’s degree in computer science, electrical engineering, or a similar field, and would have had approximately two years industry experience in networking or communication systems.” Pet. 3 (citing Ex. 1002 ¶¶ 55–58). Patent Owner does not dispute Petitioner’s proposal. PO Resp. 9. Petitioner’s proposal is consistent with the technology described in the Specification and the cited prior art. On the complete record, we adopt this level of skill.” slip op. at 9

    “We have considered the parties’ citations to the specification and find examples that support Petitioner’s view that the term “entity” is broad enough to encompass dispatchers and individual users. See e.g., Ex. 1001, 3:52–4:5, 7:18–20, Fig. 1). However, we find no disclosure that redefines “entity” or excludes dispatchers and individual users from the category of “entity.” Patent Owner’s best examples (e.g., Ex. 1001, 1:15–21, 3:59–62) are no more than non-limiting examples.

    “being present in another image or comparing that probability to a detection threshold.”). Dr. Saber was consistent with this testimony on cross-examination. Ex. 1051, 167–251. When I weigh the evidence, I find it to be one-sided, with all of the expert testimony weighing against Petitioner or avoiding the issue altogether. Thus, I would not find that Petitioner has met its burden to prove, by a preponderance of the evidence, that Zhao teaches claim limitation 1e. Moreover, even if the Majority is correct about how Zhao’s RCR algorithm works, all that shows is that the detection of object presence in a previous image can be used to disambiguate segments (e.g., limbs) of an already detected object (e.g., a person), not that it can be used to detect the object in the image in the first place, as required by the claim language. For this additional reason, I would not find that Petitioner has met its burden.” slip op. at 84

Reasons for Obviousness Based on Zhao On a limitation-by-limitation basis, Petitioner’s contentions of “obviousness” are primarily assertions of how a POSITA would have understood Zhao’s disclosures. For example, with regard to claim 1, Petitioner repeatedly asserts how “a POSITA would have understood Zhao” (Pet. 13, 18, 21, 27) and for each limitation contends that Zhao “disclosed or at least rendered obvious” (or a variation thereof) the limitation (id. at 13– 15, 17–18, 21, 23, 25–27).

  • Skill levelSkill level petitioner adoptedDecided for patent owner

    “III. ANALYSIS A. Level of Ordinary Skill in the Art The level of ordinary skill in the art at the time of the invention is a factual determination that provides a primary guarantee of objectivity in an obviousness analysis. Al-Site Corp. v. VSI Int’l Inc., 174 F.3d 1308, 1324 (Fed. Cir. 1999) (citing Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966); Ryko Mfg. Co. v. Nu-Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991)). Based on Petitioner’s contention, which Patent Owner does not dispute, we find that a person of ordinary skill in the art would have had a bachelor’s degree in mechanical engineering, chemical engineering, or a related field, and two years of experience in the research, design, or development of POCs and related hardware, software, and firmware. Compare Pet. 21, with Resp. 11. Our finding is supported by Dr. Knaebel’s testimony. Ex. 1003 ¶¶ 226–228. The level of ordinary skill in the art, as defined above, appears consistent with the disclosures of the asserted prior art and the written description of the invention provided in the ’614 patent.” slip op. at 8

    “Deane thus teaches that adsorbent housing 602 and adsorbent bed columns 508a, 508b—the asserted separation cartridge—are part of an apparatus that rests on a support surface such as a table or floor. Based on Deane’s disclosure, we find persuasive Patent Owner’s contention, and Patent Owner’s witness’s opinion, that Deane’s housing 602/adsorbent bed columns 508a, 508b (separation cartridge) cannot be removed from the receptacle by movement of the separation cartridge vertically downward. Resp. 37–38; Ex. 2001 ¶¶ 118–131. Neither Petitioner nor Petitioner’s witness, Dr. Knaebel, points to any evidence of record showing that one of ordinary skill in the art would have understood that Deane’s housing 602/adsorbent bed columns 508a, 508b (separation cartridge) could be removed from manifold 512 (receptacle) by moving housing 602/adsorbent bed columns 508a, 508b (separation cartridge) downward when the apparatus is resting on a table or floor, as taught by Deane. Pet. 42–43; Ex. 1078 ¶¶ 121–161. Petitioner fails to show that Deane’s housing 602/adsorbent bed columns 508a, 508b (separation cartridge) could be removed from the receptacle by movement of the separation cartridge in the downward (second) direction, as required by the removal direction limitation of claim 1. Petitioner, therefore, does not establish unpatentability under its axial movement theory.” slip op. at 26

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

    “Giving effect to “by movement relative to the receptacle,” when interpreting this phrase in combination with “a separation cartridge selectively removable from a receptacle,” requires that the separation cartridge is removable from the receptacle by movement of the separation cartridge itself. Interpreting the removal direction limitation to encompass a stationary separation cartridge, as Petitioner proposes, would render “by movement relative to the receptacle” superfluous. Specifically, Petitioner’s interpretation of “relative movement” does not accord weight to the recitation “movement relative to the receptacle,” which requires something other than the receptacle—the separation cartridge—to move in order for movement to occur with reference to or in comparison with the receptacle. Petitioner’s interpretation of “relative movement” as permitting removal of the separation cartridge from the receptacle when the separation cartridge remains stationary, is inconsistent with the plain language of removal direction limitation as a whole. The plain language of the removal direction limitation indicates that the separation cartridge must be removable from the receptacle by movement of the separation cartridge in a specified (first) direction. Claim 1 defines the first direction as a direction opposite the (second) direction in which the inlet and outlet are oriented. The plain language of the removal direction limitation, therefore, requires that the separation cartridge is removable from a receptacle by movement of the separation cartridge in comparison to the receptacle in a direction opposite the direction in which the separation cartridge’s inlet and outlet are oriented.” slip op. at 15

  • Strike new argumentNew argument disregardedDecided for patent owner

    “(a) Untimely new theory of unpatentability We agree with Patent Owner (Sur-Reply 4) that Petitioner’s relative movement theory is an impermissible new theory of unpatentability improperly presented for the first time in the Reply. Corephotonics, Ltd. v. Apple Inc., 84 F.4th 990, 1008–09 (Fed. Cir. 2023) (A petitioner may not raise in a reply “‘an entirely new theory of prima facie obviousness absent from the petition,’ even if the new theory is responsive to the patent owner’s response or the Board’s institution decision.”) (quoting Wasica Finance GmbH v. Continental Automotive Systems, Inc., 853 F.3d 1272, 1286 (Fed. Cir. 2017); see also Henny Penny Corp. v. Frymaster LLC, 938 F. 3d 1324, 1330–31 (Fed. Cir. 2019) (“We conclude that the Board did not abuse its discretion in . . . disregarding its [petitioner’s] new theory first raised in reply.”). Petitioner does not present the relative movement theory in the Petition, and instead presents it for the first time in the Reply. Pet. 42–43. Far from fairly meeting any argument introduced by Patent Owner in the Response, this new theory unfairly changes the thrust of the challenge.” slip op. at 27

    “3. “the rendered first webpage” Claim limitation 1dii recites “replacing the first and second objects within the 3D space with a window within a two-dimensional (2D) space in response to receiving the interaction, wherein the window includes the rendered first webpage.” Petitioner does not propose a construction for the term “the rendered first webpage” in the Petition. Pet. 13–14. Nevertheless, Patent Owner contends in the Patent Owner Response that “‘the rendered first webpage’ is the webpage that was requested by the user via the ‘first input’ from which the ‘first image’ was captured.” PO Resp. 13. As Petitioner summarizes, “[a]ccording to Patent Owner, ‘the rendered first webpage’ presented in 2D space ‘is the version that was previously received and rendered (e.g., stored in memory) from which the first image was captured. It is not a ‘live’ webpage from the Internet.’” Reply 6. Despite not proposing a construction in the Petition, Petitioner, in the Reply, asks us to construe “the rendered first webpage” to include either the previously received and rendered first webpage or a new (so called “live”) version of the first webpage rendered in response to receiving the user interaction of claim limitation 1dii. Reply 6–7. The plain and ordinary meaning of claim 1 supports Patent Owner’s argument. “To begin with, the context in which a term is used in the asserted claim can be highly instructive.” Phillips, 415 F.3d at 1314 (“To take a simple example, the claim in this case refers to ‘steel baffles,’ which strongly implies that the term ‘baffles’ does not inherently mean objects made of steel.”). Here, claim 1 refers to replacing the first and second objects with “the rendered first webpage,” which implies that the objects are not replaced with just any version of the first webpage. “Rendered” is in the past tense, suggesting a webpage that previously has been rendered. This is a clear reference to limitation 1ci, “rendering the first and second webpages.” Dr. Fuchs’ testimony is instructive. According to Dr. Fuchs, a skilled artisan “would have known that webpage rendering was a ubiquitous process for converting raw HTML code received from a web server into visible content.” Ex. 1003 ¶ 104. According to Dr. Fuchs, “[w]ebpage rendering is a core functionality of virtually all web browsers, and it would have been obvious to a [person of ordinary skill in the art] that rendering is a prerequisite step to obtaining ‘screen snapshots of actual web pages,’ as explained in Robertson’s companion Data Mountain paper.” Id. ¶ 105 (citing Ex. 1030, 5). Dr. Fuchs testifies that a skilled artisan “would have understood that Robertson’s 3D-GUI captures images of the rendered (first/second) webpages to obtain the webpage images on the object thumbnails.” Id. ¶ 107. Similarly, Dr. Fuchs testifies that “Gettman’s technique involves ‘cach[ing]’ ‘bitmap screenshots’ (captured first/second images) of rendered (first/second) webpages in local memory.” Id. ¶ 108.
