    “On remand, the Board is to determine “[w]hether the alleged inconsistency in [Petitioner’s] treatment of map images compared to other first/second versions of claim elements supports rejecting [Petitioner’s] theory on claim-construction or other merits grounds is a matter for the Board to consider in the first instance on remand, constrained by any relevantly similar now-final findings of fact and conclusions of law in the ’020 PGR and related proceedings” (CAFC Dec. 16). Thus, the two issues on remand are (1) the construction of the second map image and (2) whether A3UM teaches or suggests the claimed “second map image” under that construction.” slip op. at 10

    “c. Analysis We agree with Petitioner that the “second map image” should be construed as the map image in the second person view. Reply 5. Under Petitioner’s proposed construction, the terms “first” and “second” identify which person view that the map image is within. Id. The map image’s connection to the person view is important to how the user interacts with the interface because selecting the map image in one view does something different than selecting the map image in another, as recited in claims 14 and 46.” slip op. at 12

    “Here, we disagree with Patent Owner’s argument because it is based on the premise that the second map image is different from the first in a way that is not reflected in the claims. See Section II.C.3 supra. Even if “the claims consistently use the terms ‘first’ and ‘second’ to refer to separate and distinct elements,” A3UM’s first and second map images are separate and distinct elements for at least the reason they are included in separate and distinct views in the interface. See Pet. 63; Reply 5. As discussed in Section II.C.3, the second map image is the map image in the second person view. Here, Petitioner sufficiently shows that A3UM provides the same functionality for each person, including displaying the person in the Faces view with their name within A3UM’s overall user interface. See Pet. 62 (citing Ex. 1003, ¶215; Ex. 1005, 418–420). Patent Owner does not dispute this. See PO Resp.; Sur-reply. For the same reasons why A3UM teaches the “first map image” with respect to a first person view recited in claims 1 and 31, Petitioner has shown that A3UM also teaches the “second map image” in the second person view. See FWD 53–56. In sum, Patent Owner’s arguments are unpersuasive because they are based on an incorrect claim construction, and Petitioner has shown that claims 13 and 45 are unpatentable. 5. Claims 14–16 and 46–48 Apart from the arguments analyzed above, Patent Owner does not present separate arguments directed to the subject matter of claims 14–16 burden to show that the challenged claims are unpatentable. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). We have reviewed Petitioner’s arguments and evidence submitted in connection with the remaining limitations and find them persuasive as they are consistent with and supported by the evidence of record.

    “1. Motivation to Combine Becerra and Couckuyt Petitioner argues that a person of ordinary skill in the art would have been motivated to combine the teachings of Becerra and Couckuyt because such a person would have recognized that Couckuyt discloses useful techniques of assigning data to Becerra’s charts, including assigning data to each axis. Pet. 34 (citing Ex. 1005 ¶¶ 19, 52, Fig. 5; Ex. 1003 ¶ 224). Petitioner contends that Couckuyt discloses associating data from a “spreadsheet document” with a chart, such as a “bar graph.” Id. at 35 (citing Ex. 1006, 6:1–37; Figs. 3a, 3c). below. Petitioner’s annotations to Figure 4 identify “Drop Zones” in red and “Data Fields” in Blue. Id. at 36. Petitioner contends Couckuyt discloses a “drag-and-drop user interface (DDUI) . . . associated with a data source, such as the two-dimensional data source 300,” and Figure 4 illustrates the DDUI permitting “value data fields and the characteristic data fields . . . to be dragged and dropped into drop zones.” Id. at 35–36 (citing Ex. 1006, 7:10–13). Petitioner contends that a “primary benefit of the charting DDUI is that the user can quickly change the data that is being presented in the chart,” and using Couckuyt’s techniques, a user can “quickly change the data” and see the desired effects. Id. at 36 (citing Ex. 1006, 1:18–19; Ex. 1003 ¶ 228). Petitioner contends that when Becerra’s control panel includes multiple charts, Couckuyt’s techniques would allow dragging-anddropping data from a data source to multiple charts, and would simplify the process of assigning data to multiple control panel components. Id. at 36–37 skill in the art would have also had a reasonable expectation of success combining Becerra with Couckuyt because the combination would amount to nothing more than incorporating Couckuyt’s well-known drag-and-drop techniques into Becerra’s system. Id. at 37 (citing Ex. 1003 ¶¶ 229–231). Patent Owner responds that Couckuyt focuses on selecting a data icon that corresponds to dragging and dropping data fields, not dragging and dropping data, while Becerra teaches that selecting various data ranges from the spreadsheet is desirable. PO Resp. 36–37 (citing Ex. 1004 7:48–52; Ex. 2001 ¶ 146). According to Patent Owner, a person of ordinary skill in the art would not have been motivated to merely select data fields that do not limit the selected data in any way. Id. Patent Owner further argues Becerra’s method of binding components to a spreadsheet range and extracting formulas from a spreadsheet teaches away from the multiple chart generation scheme of Couckuyt that uses drag and dropping of data fields. Id. at 37. According to Patent Owner, Couckuyt is directed to the need for a charting DDUI that can generate multiple charts at the same time and such a need does not exist in Becerra which in turn is focused on creating a control panel that is an interactive graphics simulation.

Nor does Petitioner respond to our inquiry about whether collateral estoppel maybe applied on a limitation by limitation basis. See Pet. Reply 27. At the hearing, however, Petitioner confirmed that resolution of the issue is not necessary to our final determination. JUDGE ROSS: Do we even need to decide the collateral estoppel issue? I mean, it seems to me that if your petition clearly made out your case for the combination of Richardson and Zhao, then we don't even need to reach that. MR. CHANDRA: That’s exactly right, Your Honor. That is our position, as well. We believe collateral estoppel applies, but you don't need to decide that issue in order to find these claims unpatentable. As I mentioned before, these are the same references. We have fairly sought out all of the portions of Richardson, we cited to specific portions. Not just relying on collateral estoppel, but the teachings of the reference itself. So, while this is an issue, we believe that collateral estoppel should apply. It does not have to apply in order to find the challenged claims unpatentable. Tr. 19:9–20. We are persuaded, as discussed in Section II.G., that Petitioner has shown where Richardson in combination with Zhao meets each limitation of the claims of the ’203 patent. Accordingly, we need not address whether Petitioner has demonstrated sufficiently that collateral estoppel applies here.” slip op. at 14

  • BurdenDecided for patent owner

    “With respect to Petitioner’s allegations that rest on AAPA, we determine Petitioner has failed to show that claims 2, 10, and 11 are unpatentable. Our rules require that a petition for inter partes review must base the asserted challenges on “prior art consisting of patents or printed publications.” 35 U.S.C. § 311(b); 37 C.F.R. § 42.104(b)(2) and (4). And, a petitioner who relies on applicant admitted prior art as the basis, or part of the basis, of a ground, runs afoul of § 311. Qualcomm, 134 F.4th at 1365; see also USPTO Memorandum, Enforcement and Non-Waiver of 37 C.F.R. § 42.104(b)(4) and Permissible Uses of General Knowledge in Inter Partes Reviews (Jul. 21, 2025), available at www.uspto.gov/sites/default/ files/documents/aapa_memo_final__signed.pdf. We acknowledge but reject Petitioner’s position that its combinations discussing AAPA do not “rely” on AAPA but rather rely on U.S. Patent No. 5,793,185 (“the ’185 patent”), described in the ’203 patent as prior art. Pet. Reply 26. A petition for inter partes review must identify, “in writing and with particularity, each claim challenged, the grounds on which the challenge 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); 37 C.F.R. § 42.104 (b)(4). Here, Petitioner’s contention that the Grounds 2 and 5 actually rely on the ’185 patent when discussing AAPA is inconsistent with the Petition. In particular, the Petition does not cite to or direct our attention to any specific details from the ’185 patent to support its challenges. See generally Pet. 54–57, 76–77. Accordingly, Petitioner has failed to show, by a preponderance of the evidence, that claims 2, 10, and 11 would have been unpatentable over the combination of Richardson, Zhao, and AAPA as well as over the combination of Yu, Paparrizos, and AAPA.

  • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportDecided for petitioner

    “Patent Owner bears the burden of production to establish that its claimed invention is entitled to an earlier priority date for this fact-intensive issue. See In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1375–76 (Fed. Cir. 2016). We agree with Petitioner that the email chain does not support Patent Owner’s conception claim because it “does not discuss depositing a planarization layer, as required by both independent claims.” Pet. Reply 3. Patent Owner asserts that the inventor’s discussion of “PML” (polymer multi-layer) encapsulation in the email chain shows their conception of the claimed planarization layer because the ’389 patent describes that PMLs “‘[t]ypically’ include[e] ‘a planarization layer’ that ‘is provided to give a planar surface’ for deposition of an upper layer,” and “‘address ‘any point defects (i.e. pin holes)’ that might appear in the barrier layer’s surface.” PO Resp. 6 (quoting Ex. 1001, 1:31–37, 1:41–44, 1:56–62). We disagree with Patent Owner for two reasons. First, the challenged patent’s specification does not corroborate that the inventors conceived the claimed planarization before the challenged patent’s priority because it did not exist at the time of the email. Whether the inventors, at the time of filing, considered PMLs to typically include a planarization layer as of the claimed priority date does not support the allegation that they conceived of that same planarization layer more than a year earlier. Moreover, the ’389 patent’s teaching that “[t]ypically, for PML structures, a planarization layer 106 is formed” (Ex. 1001, 1:30–31) shows that the inventors recognized PML structures and planarization layers were distinct because only a subset of PML structures formed planarization layers, even if they do so typically. Thus, the inventor’s discussion of a PML layer in the email chain does not evidence their conception of the claimed planarization layer, as Patent Owner contends. Additionally, even if we were to understand the inventors’ mention of PML encapsulation in the emails, together with the discussion of patterning techniques for an organic layer, as discussing a planarization layer, such discussions are evidence of brainstorming ideas, rather than documenting the path taken with the claimed invention. For instance, the inventors use phrases like “don’t know if this will work,” “these are all just ‘undeveloped’ ideas,” and “looking forward to keep this discussion rolling.” Ex. 2006, 1; see also Ex. 1034, 59:22−59:18. As Petitioner argues, and we agree, these are more theoretical and future-development discussions than an exchange of a definite idea. Pet. Reply 2−3 (citing Hybritech Inc. v.

    “B. Whether Petitioner Relies on Applicant Admitted Prior Art Patent Owner asserts we should “not consider” Yamazaki-based challenges because Petitioner included Applicant Admitted Prior Art (AAPA) in those grounds. See PO Resp. 16 (citing Qualcomm Incorporated v. Apple Inc., 134 F.4th 1355 (Fed. Cir. 2025)) (holding that AAPA may not be part of the basis for an inter partes review). We disagree.

Because “[t]he Petition identifies disclosures in Ghosh that independently demonstrate the same teachings for which the AAPA is cited,” we agree with Petitioner that it does not improperly rely on AAPA for any of its challenges.

  • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner

    “C. Whether Yamazaki, Weaver, and Palanisamy Are Printed Publications under 35 U.S.C. § 311(b) Patent Owner asserts that Yamazaki, Weaver, and Palanisamy do not qualify as printed publications under 35 U.S.C. § 311(b) because they only qualify as prior art under § 102(e). PO Resp. 17. According to Patent Owner, “[e]ven though the Federal Circuit has held that such references are ‘printed publications’ under 311(b), to preserve arguments on appeal, Patent Owner submits that such an interpretation is inconsistent with the plain statutory language, the precedent, and non-public accessibility of an unpublished patent application.” Id.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundUnpatentable

    “Yamazaki does not involve multiple devices on a substrate” and Ghosh teaches “non-selective deposition of at least the barrier layer.” PO Resp. 31. We disagree with this argument because it attacks Yamazaki and Ghosh individually, rather than the combination of Yamazaki’s selective deposition and Ghosh’s plurality of devices that Petitioner asserts. See In re Keller, 642 F.2d 413, 426 (CCPA 1981). We also disagree with Patent Owner’s criticism that Petitioner fails to explain why skilled artisans would have ignored Ghosh’s non-selective deposition method for barrier layers on multiple devices. PO Resp. 32. This argument attacks a straw man as Petitioner does not propose modifying Ghosh’s method with Yamazaki’s selective deposition. See Pet. 21–23. Rather, Petitioner proposes modifying Yamazaki’s selective deposition method by applying it to Ghosh’s teaching of encapsulating a plurality of OLED devices. Id. Next, Patent Owner asserts that skilled artisans would not have extended Yamazaki’s single-device fabrication/encapsulation method to a plurality of devices on a substrate because doing so would “multiply defects and errors, drop the yield exponentially, and increase the cost.” PO Resp. 34. Patent Owner asserts that precision/defect problems would be particularly acute when using Yamazaki’s inkjet method to print devices’ electro luminescence layers. Id. at 35–36. We disagree. Even if extending Yamazaki’s method to Ghosh’s multiple devices comes at a cost of potential defects, that tradeoff would not undermine Petitioner’s proffered combination given Petitioner’s articulated benefits outline above, including facilitating manufacturing display panels for OLEDs with improved throughput, improved productivity, and reduced manufacturing costs, as compared to fabricating/encapsulating just a single device. See Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000) (“The fact that the motivating benefit comes at the expense of another benefit, however, should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another.”). It also does not matter that “inkjet printing yielded devices of half the efficiency than spin coating,” as Patent Owner asserts (PO Resp. 35), because Petitioner does not need to show that Yamazaki’s inkjet printing would be the best option for batch fabrication/encapsulation, only that it would was a suitable one from which the prior art did not teach away. See Par Pharm., Inc. v. TWi Pharms., Inc., 773 F. 3d 1186, 1197–98 (Fed. Cir 2014). That is, Petitioner does not need to show that Yamazaki’s inkjet method was an improvement over other known fabrication/encapsulation methods, so long as it was a known fabrication/encapsulation method and skilled artisans would understand that implementing it for a plurality of devices had known advantages over fabricating/encapsulating a single device, which Petitioner identifies. See Pet. 22. We also agree with Dr. Subramanian that skilled artisans would have a reasonable expectation of success in making the proposed combination given similarities between the references (both are directed to encapsulation of an OLED display device with multiple thin-film layers and at least the first encapsulation is selectively deposited) and because “as the ’389 patent admits, in the prior art it was conventional to use batch fabrication to manufacture OLED display devices with thin-film encapsulation.” Ex. 1003 ¶ 86. As Dr. Subramanian explains, a particular advantage of inkjet printing is that it scales well to larger areas and it was known at the time of the ’389 patent that inkjet could be used to print multiple devices on a glass substrate. Ex. 1032 ¶¶ 2, 27–28. Patent Owner’s argument that “Yamazaki’s methods are far from ready for manufacturing” (PO Resp. 34) goes well beyond what is necessary to show that skilled artisans would have had a reasonable expectation of achieving what is claimed. See Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1367 (Fed. Cir. 2016). Given Petitioner’s analysis outlined above, we agree with Petitioner that it would have been obvious to skilled artisans to fabricate and encapsulate multiple OLED devices on a substrate using Yamazaki’s ink-jet methods. slip op. at 15

Next, Patent Owner faults Petitioner for failing to show that using Ma’s Liq dopant in Diekmann’s/Suzuki’s ETL would result in lower diffusion or higher efficiencies as compared to Diekmann’s/Suzuki’s preferred n-dopants, which included cesium, barium, or lithium fluoride. PO Resp. 31–35; see PO Sur-reply 4–5. We disagree with Patent Owner’s argument because Petitioner does not need to show that Ma’s Liq n-dopant “was an improvement in a categorical sense” over Diekmann’s/Suzuki’s n-dopants, so long as Ma’s n-dopant was known and one skilled in the art would understand that implementing it had advantages. See Intel Corp. v. Pact XPP Schweiz AG, 61 F.4th 1373, 1381 (Fed. Cir. 2023) (quotation marks omitted); In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004) (“[O]ur case law does not require that a particular combination must be the preferred, or the most desirable, combination described in the prior art.”). Petitioner does not assert skilled artisans would have used Liq because it was a superior to Diekmann’s/Suzuki’s preferred dopants, but because doping ETLs with Liq had known benefits including lower driving voltage and enhanced power efficiency from enhanced carrier injection increased transport conductivity, as compared to an undoped device. Pet. 37 (citing Ex. 1010, 813). That other potentially suitable or even superior n-dopants were also known does not make Liq nonobvious. Given Liq’s benefits outlined above, Petitioner has articulated sufficient reasoning with rational underpinning to support the legal conclusion that its proffered combination of Ma’s known dopant in Diekmann’s/Suzuki’s device would have been obvious to one skilled in the art.

    “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.

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.
