“Beel actually discloses the following: [0321] On the peripheral device 32 the video packets are received at the corresponding plug and play port, e.g. the USB port 11, read by the Human Interface Driver (HID) interface handler 13, unpacked to remove HID protocol headers in an unpacker 20 and then transmitted to the communications network by a transmitter 21. The network can be wireless for example WiFi or LiFi network. [0322] Having been routed over a communications network to the base unit 33, the incoming stream is read from the communications interface such as a WiFi access point 22, unpacked in an unpacker 25, decoded in a decoder 26 and then inserted into a suitable composition such as an OpenGL based composition in the compositor 29 for display on a central display device. Ex. 1005 ¶¶ 321–322 (emphasis added to portions quoted by Petitioner). Patent Owner notes that “[t]he Petition mistakenly cites to ¶ 322 of Beel but quotes ¶ 321.” PO Resp. 20 n.3. However, it appears that Petitioner has grafted together a portion of paragraph 321 that introduces peripheral device 32 with a portion of paragraph 322, which discusses features of base unit 33. However, this grafting has been done in such a way as to convey (incorrectly) that peripheral device 32, not base unit 33, includes unpacker 25, decoder 26, and compositor 29 that process the first processed video data received by the first peripheral device to generate second video data. Dr. Almeroth’s testimony, which copies Petitioner’s incorrectly altered quotation to paragraph 322 of Beel, is unreliable as to this claim limitation and is entitled to no weight.4 Thus, Petitioner has no expert testimony on which to rely for this claim limitation.” slip op. at 19

“5 At the oral argument, when challenged on its reliance on paragraph 322, Petitioner argued that paragraph 321 of Beel teaches this limitation. Tr. 22:26–23:24. Petitioner did not make this argument in the Petition and, instead, raised it for the first time during oral argument; thus, it will not be considered. See Dell Inc. v. Acceleron, LLC, 884 F.3d 1364, 1369 (Fed.

Even if we were to consider this new argument, it would not be persuasive. As Patent Owner observes (PO Resp. 20), any processing performed by peripheral device 32 in paragraph 321 is on data received from the processing device and destined for the base station via the network, rather than data flowing in the direction of the first processed video data of claim 1.” slip op. at 22

“We do not agree with Patent Owner’s arguments disputing Petitioner’s backward compatibility rationale for combining the teachings of Yan and Takeda. Patent Owner’s arguments are misplaced because they are premised incorrectly on Takeda’s teachings being limited to 5G NR (i.e., standalone 5G NR), and the proposed combination requiring “mixing standards and behaviors.” To the contrary, Petitioner explicitly asserts that “Takeda states that its teachings are applicable to both 4G and 5G”––i.e., non-standalone 5G. Pet. 14 (citing Ex. 1007 ¶ 239). Likewise, instead of mixing 5G and 4G standards and behaviors as argued by Patent Owner, Petitioner merely proposes retaining Yan’s 4G method of allocating UL channel resources sets with Takeda’s teaching of 5G NR BWPs. See Pet. 14–15. We credit Dr. Roy’s testimony that a person of ordinary skill in the art would have been motivated to modify Takeda’s teachings with Yan’s teachings to provide Takeda with backwards network capability because it is supported by the cited evidence of record. See Ex. 1002 ¶¶ 105, 106 (citing Ex. 1007 ¶ 239; Ex. 1031, 1, 3; Ex. 1033, 5:23–31; Ex. 1034, 10; Ex. 1035, 1, 5; Ex. 1037, 31). Moreover, as pointed out by Petitioner, Dr. Shimony’s deposition testimony regarding the usefulness of backward compatibility and the importance of a non-standalone UE having the ability to communicate over both 4G and 5G standards supports Dr. Roy’s testimony, yet undermines Patent Owner’s arguments. See Ex. 1050, 178:16–182:16; Pet. Reply 14–15.

“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.

Accordingly, we need not address whether Petitioner has demonstrated sufficiently that collateral estoppel applies here.” slip op. at 14

“Our Practice Guide states, that “[o]nce a trial is instituted, the Board may decline to consider arguments set forth in a preliminary response unless they are raised in the patent owner response.” Consolidated Trial Practice Guide (“Practice Guide”), 52 (Nov. 2019) (citing In re Nuvasive, Inc., 842 F.3d 1376, 1381 (Fed. Cir. 2016) (explaining that a patent owner waives an issue presented in its preliminary response if it fails to renew the issue in its response after trial is instituted)).12 In addition, in our Scheduling Order, we stated that “Patent Owner is cautioned that any arguments not raised in the response may be deemed waived.” Paper 9 at 10; see also Practice Guide, 94 (same). Patent Owner confirmed at the Oral Hearing its understanding that arguments raised in its Preliminary Response and not reasserted in its Patent Owner Response were not appropriate for consideration during trial. Tr. 4:10–6:17. Petitioner does not identify any particular argument raised in the Patent Owner Preliminary Response that is not present in the Patent Owner Response. But, in this Final Written Decision, we do not consider arguments made in the Patent Owner Preliminary Response and instead assess only those fairly presented in the Patent Owner Response.” slip op. at 15

Claims 1–11 are unpatentable as obvious over the Richardson-based grounds; the Yu and Paparrizos grounds do not establish unpatentability.
RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“Petitioner contends that a person of ordinary skill in the art, “[a]s of the claimed priority date of July 3, 2014, . . . would have been a person with a bachelor’s degree in electrical engineering or its equivalent and two years of experience in the field of electrical engineering including some experience in design of battery charging systems.” Pet. 21 (citing Ex. 1003 ¶¶ 19–30). Patent Owner “does not propose a different level of skill in the art[.]” PO Resp. 16. In light of the record before us, we adopt Petitioner’s proposal regarding the level of ordinary skill in the art, because it is supported by the testimony of C. Arthur MacCarley and not disputed by Patent Owner.” slip op. at 11

“Petitioner submits there are no formal claim constructions necessary in this proceeding[.]” Pet. 22. Patent Owner also “does not propose any terms need to be construed.” PO Resp. 15. As neither party proposes an express construction for our consideration and because we determine that claim construction is not necessary, we do not expressly construe any claim terms. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (holding that “only those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy”); see also Nidec Motor Corp. v.

- PTAB / AIA Trials › §315(e) estoppelNot reached
“arguments relating to whether the prior findings are “necessary to the determination” or whether estoppel applies to arguments relating to Richardson being inoperative. See Pet. Reply 27. 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. Petitioner’s alternative allegations based on Epower-20/Epower-21 are considered below.” slip op. at 18
