“We decline Patent Owner’s invitation to construe “during a frame” of “independently controlling simultaneous data acquisition with each of the first and second channels during a frame” by importing the extraneous limitations “at some point between the beginning and the end of the exposure interval during which the image sensors capture a single image.” As pointed out by Petitioner, Patent Owner’s proposed construction is unsupported by the language of claim 22 and the ’180 Specification because Specification does not disclose an exposure interval nor suggest “during a frame” is limited to an exposure interval. Patent Owner and its expert Dr. Saber cite only extrinsic evidence (Exs. 2006, 2009) to support its argument that claim 22 should be limited to an “exposure interval during which the image sensors capture a single image.” See PO Resp. 16–17; Ex. 2020 ¶ 64. Similarly, Patent Owner relies only on extrinsic evidence (e.g., Ex. 2011, 1; Ex. 2022, 1; Ex. 2020 ¶ 66) to limit “during” to “at some point between the beginning and the end.” See id. at 18. When considered in the context of claim 22 and the ’180 Patent Specification which do not limit “during a frame” to an exposure interval, we find that we cannot rely on Patent Owner’s citations to extrinsic evidence to yield a reliable construction for “during a frame.” As demonstrated in the analysis below, we need not provide an explicit construction for “during a frame” to resolve the parties’ disputes regarding the merits of the patentability challenges. See Realtime, 912 F.3d at 1375. We apply the ordinary and customary meaning for “during a frame.” To the extent that an explicit identification of the ordinary and customary meaning may aid the understanding of our analysis, consistent with the language of claim 22 and the ’180 Patent Specification, we find that the ordinary and customary meaning for “during a frame” is “during the period of time that data for an image frame is acquired.” See Ex. 1001, code (57), 20:6–24, 25:23–35.” slip op. at 12

See Dynamic Drinkware, 800 F.3d at 1379–1380. For a claim in a later-filed application to be entitled to the filing date of an earlier application, the earlier application must provide written description support for the claimed subject matter. Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010). To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997); see also VasCath v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed.

Patent Owner’s arguments fail to meet this burden of production because, aside from addressing deficiencies of written description support the ’854 Provisional Application provides written description support for all of the limitations of the claimed invention. See PO Resp. 60–64; PO Sur-reply 25–28. Specifically, Patent Owner does not address written description support in the ’854 Provisional Application for “independently controlling simultaneous data acquisition with each of the first and second channels during a frame”––limitation [22.3]––the heart of the parties’ claim construction disputes addressed above in Section II.A. See PO Resp. 60–64; PO Sur-reply 25–27. Accordingly, Patent Owner has not met its burden of production in coming forward with evidence or argument to show possession of the claimed invention in the ’854 Provisional Application. As a result, the burden of production does not shift back to Petitioner, and, therefore, the ’180 Patent is not entitled to the benefit of the August 25, 2004, filing date of the ’854 Provisional Application.” slip op. at 23

“We adopt the definition clearly and unambiguously set forth in the specification, which was likewise adopted by the Court in the related litigation. See Pet. 7–8, 55; Pet. Reply 1–2 (district court construing the term to mean “the time the image sensor collects and integrates signal from the scene”). The specification states that the integrated photo-charge “is directly related to the time the image sensor collects and integrates signal from the scene,” and that “[t]his is known as integration time.” Ex. 1001, 4:4–7.

- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed board ownOther
“We construe “during a frame” to mean the period during which data for a single frame of an image is captured. The limitation is satisfied where the per-channel integration time is effectuated during the frame; it does not require that the integration time be re-determined mid-frame, nor does it require actuation of a “charge integration switch.” The specification’s only use of the phrase confirms this reading: “each camera channel is controlled during a frame under an independent integration time.” Ex. 1001, 3:45–50. Consistent with that usage, the specification describes selecting an integration time for each channel and then integrating the photo-signal “within a single frame of data,” and describes placing the charge-integration switch in a state to allow charge to accumulate for the selected period and then transferring the accumulated charge upon completion of the integration period. Id. at 4:51–54, 11:3–18. We decline Patent Owner’s proposal to require in-frame actuation of a charge-integration switch, for the same reason we decline to import that structure into “integration time.” We also decline to read the phrase to require mid-frame re-determination of the integration time, because the patent’s own embodiment selects an integration time and then integrates charge during the frame under that selected time. Ex. 1001, 4:51–54, 11:3– 18. So construed, “during a frame” is not redundant of the independentclaim limitation: it adds that the per-channel control occurs within a single frame (intrascene), as distinct from adjustment from one frame to the next (interscene).” slip op. at 15

In addition, we agree with Petitioner that one of ordinary skill in the art “would have found it obvious to use Parkin’s CoFeB layer in place of Bowen’s electrodes to increase TMR” in light of Parkin’s explicit teachings. Pet. 27; Ex. 1024 ¶ 133. In particular, Parkin explicitly teaches that “very high TMR values are unexpectedly found for MTJs with highly textured (100) MgO tunnel barriers but with nominally amorphous storage layers.” Ex. 1062, 18:49–51. Notably, Parkin provides that “[t]he TMR of the device of F[igure] 3A is nearly two times higher than the highest TMR ever reported in prior art devices using conventional alumina tunnel barriers.” Id. at 18:63–65; Pet. 27. And as we discuss above, Parkin teaches that Figure 3A’s MTJ may be inverted, such that the storage layer is formed beneath the tunnel barrier. Ex. 1062, 17:7–10. In addition, we agree that one of ordinary skill in the art would have had a reasonable expectation of success in modifying Bowen in the manner Petitioner proposes, as forming electrodes with CoFeB alloys was known. Pet. 28. As Petitioner argues, “forming electrodes with CoFeB alloys in MTJs was known and had been successfully done,” and thus we are persuaded that “one of skill would have found it to be a straightforward, predictable, and desirable improvement to TMR, Hf, and Hc in Bowen’s” slip op. at 21

“We find unavailing Patent Owner’s arguments that Bowen teaches a “radically different manufacturing process[] from the claimed invention,” and that Bowen “went to heroic lengths to provide a crystalline (001) bottom electrode that provides a template for epitaxially growing a crystalline MgO(001) layer.” PO Resp. 2 (emphasis omitted). Patent Owner describes in detail Bowen’s specific manufacturing process, including the specific structure of the MTJ manufactured, and argues the claimed invention differs. PO Resp. 30–33. These arguments are inapposite. Petitioner cites the specific teachings Petitioner relies on from Bowen, rather than adopting the entirety of Bowen’s process or MTJ. See, e.g., Pet. 21–36 (citing the portions of Bowen—that in combination with Parkin—teach claim 1).

“A reply may only respond to arguments raised” in the patent owner response. 37 C.F.R § 42.23(b). The Consolidated Trial Practice Guide states that responding “does not mean proceed[ing] in a new direction with a new approach,” and “[w]hile replies . . . can help crystalize issues for decision, a reply . . . that raises a new issue or belatedly presents evidence may not be considered,” that is, “Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.” Consolidated Trial Practice Guide § II.I (last updated Dec. 12, 2025) (“CTPG”), available at https://www.uspto.gov/patents/ptab/trial-practice-guide. We are not persuaded by Patent Owner’s assertions that Petitioner’s reply arguments on Parkin should not be considered. As discussed supra Section II.D.3.i above, the Petition includes the assertion that if Parkin’s CoFeB electrodes were used to modify Bowen, the MgO polycrystalline or single-crystal layer would still have the same 001 orientation. Pet. 33–34 (citing Ex. 1024 ¶ 129; Ex. 1062, 9:58–10:2, 18:49–51; Ex. 1005, 4:30–32). Petitioner’s support in the Petition references disclosures relating to Parkin’s Figure 3A (Ex. 1062, 18:49–51), which discloses a MgO(100) tunnel barrier, and the Petition also notes that the structure of Figure 3A may be inverted. Pet. 40 (citing Ex. 1062, 17:7–10). Patent Owner’s arguments, in large part, are related to Petitioner’s arguments in the Reply relating to Parkin’s Figure 11. Parkin’s Figure 11 is an embodiment where the structure of the devices of Figure 3A is inverted. See Ex. 1062, 22:29–33. We do not find that Petitioner’s arguments that are at issue in the Reply represent a new direction in its approach—the Petition is clearly based on the assertion that if Parkin’s CoFeB electrodes are used in Bowen, the device would have a MgO(001) tunnel barrier layer. Further, the Petition refers to Parkin’s disclosure that the device in Figure 3A may be inverted, which would be encompassed by the Figure 11 embodiment. Moreover, in the Institution Decision, we invited additional briefing on whether Parkin’s storage magnetic electrode was an amorphous ferromagnetic electrode, which relates to Parkin’s Figure 11 (Dec. 28–29). We are also not persuaded by Patent Owner’s argument that the Petition’s assertions do not correspond to what Petitioner argues in the Reply because they were referred to in the section pertaining to limitation 1[e]. The Petition includes a cross-reference in the limitation 1[d] discussion on the tunnel barrier layer limitation: “if Sunai’s or Parkin’s CoFeB electrodes are used as described in Claims 1[e] and 2 in this Ground, one of skill would understand that the MgO . . . would still have the same (001) orientation.” Pet. 33. Further, Petitioner’s arguments in its Reply properly respond to arguments made on contested issues. Patent Owner’s contentions on the merits in its Response are largely based upon the assertion that the modified MTJ of Bowen would not have a MgO(001) layer as claimed. See PO Resp. 4–10, 18–48. Petitioner’s reply arguments on Parkin relate to whether there would be a MgO(001) layer in its structure, so we find that Petitioner’s arguments on Parkin in its Reply (Pet. Reply 2–5) and the related evidence are appropriately responsive. slip op. at 17

“We find that there is sufficient evidence in support of Petitioner’s assertion of the rationale to replace Bowen’s electrodes with CoFeB and anneal them. As discussed supra Section II.D.ii.2, Parkin’s Figure 11 depicts and describes a storage electrode that may be composed of amorphous CoFeB, with the formation of a MgO(001) barrier layer atop it. See Ex. 1062, 22:29–66. Patent Owner argues that Parkin’s benefits are because its CoFeB electrode is amorphous (PO Resp. 51–52), but this is not accurate. In Parkin, the CoFeB amorphous electrode crystallized at the interface layer between the barrier and the electrode. Id. at 19:6–19. Parkin discloses that higher TMRs were attributable to the crystallization of CoFeB. Id. at 18:63–19:22. Parkin also discloses that its completed CoFeB- MgOH(001)-CoFeB device was annealed with resulting high TMRs. Id. at 17:60–18:16. These disclosures provide support that one of skill in the art would have been motivated to replace Bowen’s electrodes with CoFeB and anneal to crystallize them because of the known improvements of TMR. Additionally, Parkin’s disclosures support that the results of the combination would have been predictable. That is, Parkin actually discloses an amorphous CoFeB electrode, formation of a MgO(001) tunnel barrier on the amorphous electrode, and annealing the assembly, with a resulting high TMR. Accordingly, Petitioner has provided reasoning with rationale underpinning for the motivation to combine. See KSR, 550 U.S. at 415 (“[t]he combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results”).” slip op. at 31

“We agree with Petitioner that the ’690 patent does not limit the term “probe” to channel assessment. Pet. Reply 2–4. Reviewing the intrinsic evidence, the “Technical Field” of the ’690 patent states that “some embodiments relate to channel assessment probes,” implying others do not. Ex. 1001, 1:13–14. The ’690 patent further states that “receiver determined probes may be used in a variety of applications” including to “discover hidden nodes” and “off-site network diagnosis.” Id. at 2:20–27. In addition, the ’690 patent states that probes may be used for “network maintenance procedures,” to “replicate a potential problem, reach or discover a distant or previously undetected node on the network, or assist with network admissions procedures.” Id. at 4:25–38. Turning to the claims of the ’690 patent, the evidence of record does not establish that the independent claims recite anything unique or specific to channel assessment (although their scope covers that purpose). Furthermore, dependent claim 7 of the ’690 patent recites that the “probe” is used to diagnose a network problem, and dependent claim 13 recites that the “probe” is used to identify a hidden node. Restricting the independent claims to probes used solely for channel assessment would be contradictory to these dependent claims. Littlefuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed.

“We agree with Petitioner that a “physical layer probe” is “a probe that relates to the physical layer.” The term does not appear per se in the specification of the ’960 patent, nor in the prosecution history, but only in claims 9, 17, and 19. However, the term “physical layer” is well-known and is the first layer in the Open Systems Interconnection (OSI) network model. See, e.g., Ex. 1021, 35–40, 69; Ex. 1002 ¶¶ 49–50. The physical layer is used to transmit digital bits over a network, and defines the timing, mechanical, and physical network characteristics required for transmitting the data bits. Hence, a “physical layer probe” is a probe that relates to the physical layer. We need not, and do not, construe the term further to resolve the parties’ dispute. See Realtime, Vivid Techs., supra.

“We have considered Petitioner’s arguments and Dr. Shamos’s testimony in light of Oborne’s disclosure, but find Patent Owner’s arguments and Dr. Malek’s responsive testimony to be more persuasive. We agree with Dr. Malek that, in Oborne, “device fingerprinting simply refers to identifying a device and the user associated with that device.” Ex. 2009 ¶ 111. Specifically, paragraph 26 of Oborne (quoted above) discloses authentication of a user, where “device fingerprinting” is utilized to verify a user’s identity where a user exclusively uses a client device such as a smartphone or laptop computer. Ex. 1011 ¶ 26 (emphasis added). The use of the device fingering for determining the device identity in order to authenticate a user is corroborated by the disclosures in paragraph 47 of Oborne which refer, in part, to the “<client_details” which can include a “<client_type>smartphone” and “client_fingerprint>font list, MAC address, memory size, memory.” Id. ¶ 47 (emphasis added). So, contrary to Petitioner’s arguments, we do not discern any disclosure in Oborne that “device fingerprinting” ties a token to a particular device. See, Ex. 1011 ¶¶ 26, 47. Rather, Oborne’s disclosures support Dr. Malek’s testimony that, contrary to Petitioner’s position, “device fingerprinting could be used to limit a token to a set of fingerprinted devices, such as each device belonging to the user.” Ex. 2009 ¶ 113. Moreover, Petitioner (and Dr. Shamos’s) statement that “the first device’s fingerprint would not match” the fingerprint for the second device merely provides a possible outcome of device fingerprinting, but does not explain why one of ordinary skill would be motivated to use device fingerprinting to make the “second device’s token . . . invalid in the first device,” or make the “token for the second device . . . a new credential,” or point to disclosures in Oborne that would support such a motivation. See Pet. 34–35; Ex. 1005 ¶ 228. Thus, we find that Petitioner’s contentions as to this limitation lack sufficient specificity to explain how Oborne teaches the limitation. See Netflix, Inc. v. DivX, LLC, 84 F.4th 1371, 1377 (Fed. Cir. 2023) (“Ultimately, it is the petitioner’s burden to present a clear argument.”); Intelligent Bio-Sys. v.

We further agree with Patent Owner that Oborne’s disclosure of “device fingerprinting” is limited, and does not describe how it would be implemented for a user with two devices. See PO Resp. 41–42. Therefore, Dr. Shamos’s cited Declaration testimony is “conclusory, adds little to the conclusory assertion for which it is offered to support, and is entitled to little weight.” Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB August 24, 2022) (precedential); see also 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”).” slip op. at 41

Ex. 1012 ¶¶ 97, 99; Pet. 60. Although a credential image would presumably need to be retrieved or generated in some manner, and associated with the key signatures in some manner, Petitioner also does not sufficiently explain how this would work in the proposed combination, or how the user would transmit the scannable key signature to the recipient. Although proof of physical or bodily incorporation is not required, a satisfactory explanation of “how the combination of the . . . references [is] supposed to work” is necessary to support “a conclusion that a relevant skilled artisan would have been motivated to make the combination and reasonably expect success in doing so.” Personal Web Techs., LLC v.

“Petitioner has provided sufficient articulated reasoning to support the rationale for the combination of Oborne and Purves for the teaching of the limitation “requesting the credential.” As Petitioner points out (Pet. Reply 15), in the discussion of claim 23, the Petition refers to claim 22, which requires “generat[ion] of the credential.” IPR487, Pet. 37; see also Ex. 1005 ¶ 301. That discussion explains that a person of ordinary skill in the art would be motivated to combine Oborne and Purves because “the teachings of Purves would be recognized as useful to add new credentials to the digital wallet of Oborne’s PPT apparatus (for example, where a user had not yet added any credentials, or where adding further credentials were desired).” IPR487, Pet. 35 (citing Ex. 1005 ¶ 295). Dr. Shamos testifies that the credential that Purves teaches is a new gift card or reloadable prepaid card. Ex. 1005 ¶ 294 (citing Ex. 1013 ¶ 83). The Petition explains that a person of skill “would generate the new credential,” as Purves teaches that a customer may obtain a new gift card or prepaid card. IPR487, Pet. 37 (citing Ex. 1013 ¶ 83). Dr. Shamos testifies that “when the processor determines that no matching credential is stored” “a new credential would be generated because “the purpose of Oborne’s tokens is to represent a credential” and “by generating the new credential, the user becomes able to benefit from 9 We note that Patent Owner does not assert that there would be any security concerns with the combination of Oborne and Purves under this ground, which is based on the Purves’ embodiment concerning requests for a gift card or prepaid card credential. See PO Resp. 48–50. 49 Oborne’s tokenization system, and if the credential was already stored, there would be no reason to generate it, since it would already exist.” Ex. 1005 ¶ 298. For claim 23, which “requests the credential from the issuing agency,” Dr. Shamos further testifies that “when new credentials were generated upon user request, such as the gift and prepaid cards taught by Purves. . ., it would be natural for the issuer to store such new credentials, at least until they were sent to the recipient, and more practically for as long as they remained valid, so that the issuer’s system would confirm their existence and validity.” Id. ¶ 304. Patent Owner does not present any arguments challenging the sufficiency of Petitioner’s showing as to claim 22. As explained for claim 22, Petitioner relies upon Purves to teach the generation of a credential like a gift card or reloadable prepaid card, which would be useful to have as a credential in Oborne, and Patent Owner does not dispute this rationale. IPR487, Pet. 35; see generally PO Resp. As Petitioner also explains, a user would want to store credentials like a gift card or reloadable prepaid card in Oborne’s PPT, at least until they were sent to the recipient, “and more practically for as long as they remained valid, so that the issuer’s systems could confirm their existence.” IPR487, Pet. 38. As Dr. Shamos testifies, this is taught by Purves’ disclosure of retrieving the user’s “payment account information from the payment account issuer,” with user’s consent, and the issuer responding with information for data for establishing a virtual wallet including a “payment account in a virtual wallet.” See Ex. 1005 ¶ 301 (citing Ex. 1013 ¶¶ 83, 107–108 (“The user may then indicate that they desire to add a new payment account to their virtual wallet”)).

“We also find Dr. Malek’s testimony on this point more persuasive than Dr. Shamos’s testimony. See Ex. 2009 ¶¶ 165–170; Ex. 1048 ¶¶ 35–39; 72 Pet. Reply 27–28 (citing Ex. 1048 ¶¶ 55–60). For example, Dr. Shamos testifies that the combination’s use of obscured credential images would not “have risked exposure of the key signatures themselves since the image does not depict or otherwise convey the key signatures.” Ex. 1048 ¶ 37. However, although Petitioner fails to sufficiently explain the proposed combination, as discussed above, presumably there is some relationship between the credential image and the key signatures, since the proposed combination purportedly allows for the user to identify items that were previously selected for release, in order to provide the relevant key signatures to the recipient. Pet. 62–63; Ex. 1005 ¶ 367; Ex. 1048 ¶ 33. In contrast, Dr. Malek testifies, and we agree, that providing an unencrypted image of a credit card, for example, would inform potential attackers of the payload of the credential that is being attempted to be securely transmitted which is a security vulnerability. Ex. 2009 ¶ 169. Although Dr. Shamos testifies that Purves teaches associating wallet items with obscured or representative images and that such representative images were routinely used in virtual wallets, Ex. 1048 ¶¶ 35, 38 (citing Ex. 1013 ¶ 85), we do not find this persuasive in the context of the proposed combination with Stafford’s system for securely storing, transmitting, and authenticating credential information relating to an entity, with use of key signatures. Ex. 2009 ¶ 160; Ex. 1012 ¶ 2. Accordingly, Petitioner’s generic reasons for the proposed combination, coupled with Petitioner’s lack of specificity as to the proposed combination, leads us to determine that Petitioner’s reasons explaining why a person of ordinary skill in the art would have combined Stafford and 73 Purves are not persuasive in light of the teachings of those references and the testimonial evidence provided by Dr. Shamos, as discussed above. Further, as also discussed, the prior art fails to teach an “OVER engine” as claimed. Therefore, Petitioner has not established by a preponderance of the evidence that the claims 1, 15, and 21 are unpatentable over Stafford and Purves. We determine that Petitioner has not demonstrated by a preponderance of the evidence that claims 3–5, 7–14, 16, 18–20, 22–26, and 28–33, which depend from claims 1, 15, and 21, are unpatentable over Stafford and Purves. Further, we have reviewed Petitioner’s showing for the obviousness of claims 2, 6, 17, and 27 over Stafford, Purves, and Neafsey (Pet. 79–81), and the argument and evidence presented fail to remedy the deficiencies of the associated independent claims.

Petitioner contends that Lys is prior art to the ’546 patent at least under pre-AIA 35 U.S.C. § 102(b). Pet. 2–3. 5 JP2006-228529, published August 31, 2006 (Ex. 1006, code (43)) (“Hiroyuki”).

Patent Owner applies Petitioner’s asserted level of ordinary skill in the art. PO Resp. 7–8. For the purposes of this Decision, we adopt the assessment offered by Petitioner as it is consistent with the ’546 patent and the prior art before us. See Okajima v.

“The “context” is typically evaluated by reviewing the intrinsic record. See e.g., Regeneron, 130 F.4th at 1380–84. Here, as discussed above, the ’546 patent has multiple disclosures where a curtain lamp has a single light-emitting diode in one light-emitting diode string. See Ex. 1001, 1:33–36, 6:15–20, 6:27–40, 8:25–45. In particular, the ’546 patent similarly discloses a first curtain lamp with one LED in one light string, as well as a second curtain lamp, which provides further support for Petitioner’s proposed interpretation. Id. at 8:25–45. Although Patent Owner argues that Figures 7 and 8 disclose multiple LEDs and light strings in curtain lamps, other embodiments and claims explicitly indicate single components in a “curtain lamp.” “[T]here is a strong presumption against a claim construction that excludes a disclosed embodiment.” See In re Katz Interactive Call Processing Patent Litig., 639 F.3d 1303, 1324 (Fed. Cir. 2011). Given that certain embodiments and claim 8 disclose a curtain lamp with one light string with one LED, we decline to interpret the claim to prohibit Petitioner’s interpretation. Additionally, we do not find that Petitioner’s claim interpretation renders the claim terms nonsensical or illogical. See Becton, 616 F.3d at 1255. Patent Owner asserts otherwise, arguing that Petitioner’s interpretation is based upon a “nonsensical” or “absurd[]” argument, there is no reason to have both a master and slave control unit to operate a single LED, and the interpretation renders most of the components superfluous. See PO Sur-reply 12; PO Resp. Supp. Br. 5. As discussed above, however, although the ’546 patent does not appear to provide any explanation for why there are master and slave control units to operate a single LED, the patent nevertheless discloses that in embodiments. This situation is also distinguishable from Becton, where “unequivocal language” of the claim recited “spring means ‘connected to’ the hinged arm,” such that interpreting the spring means and the hinged arm as the same structure would have rendered the claim nonsensical. Becton, 616 F.3d at 1254–55. Becton further found that interpreting the spring means and hinged arm as the same structure would be inconsistent with descriptions of the elements in the specification. Id. Here, in contrast, the ’546 patent Specification is replete with disclosures of a curtain lamp having one light string with one LED, and claim 8 is directed to the same. Accordingly, we adopt Petitioner’s interpretation of these claim elements.” slip op. at 36

“Although Patent Owner argues that Petitioner’s arguments in the Reply on “light strings” and “curtain lamp” as they relate to a single LED are improper, we do not agree. As Patent Owner acknowledges, the Petition and Dr. Schubert’s original declaration stated that a “curtain lamp” is “commonly understood to be one or more light strings.” See PO Sur-reply 12; see also Pet. 8; Ex. 1003 ¶ 37. Patent Owner did not contest Petitioner’s interpretation in its Response. See PO Resp. 15. Patent Owner did, however, argue that Kuang did not teach or suggest “light strings” in any form and therefore did not teach a “curtain lamp” under Petitioner’s definition of the same. PO Resp. 15–17. A petitioner reply may respond to arguments raised in a patent owner’s response under 35 U.S.C. § 42.23(b), and here Petitioner’s argument that a light string may have a single LED is properly presented in its Reply in response to Patent Owner’s arguments. Further, Patent Owner was not only aware that Petitioner had taken the position that a “curtain lamp” could be a single “light string,” but Patent Owner also did not dispute Petitioner’s interpretation.8 Our view, therefore, is that Petitioner’s argument that a curtain lamp may be a single LED is proper because it is corollary to Petitioner’s reply arguments on light strings. That is, Petitioner’s assertion follows from the reply arguments on light strings and the unopposed interpretation of curtain lamp as a single light string. Additionally, to the extent there could be any prejudice to Patent Owner by these light string and curtain lamp arguments, Patent Owner has had opportunities to address them by supplemental briefing.” slip op. at 32
