    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

      “We agree that Patent Owner’s proposed claim construction is wholly unsupported by, and inconsistent with, the language of independent claims 1, 7, and 13, and the aims of the ’670 Patent Specification. See Ex. 1001, 2:3– 25, 9:32–10:5, 12:51–67, 18:54–19:6, 19:26–42, 20:12–26. Moreover, the cited extrinsic evidence––testimony by Patent Owner’s expert Dr. Lomp–– does not support Patent Owner’s proposed construction because it is internally inconsistent and also undermined by Dr. Lomp’s inconsistent deposition testimony. See Ex. 1036, 11:6–17, 12:9–12; Ex. 2010 ¶¶ 40, 48. Similarly, the extrinsic evidence cited by Petitioner (e.g., Exs. 1037, 1038, 2009) undermines Patent Owner’s position emphasizing the intended recipient devices of SIB1. In summary, we decline to adopt Patent Owner’s proposed claim construction because it is unsupported by the claim language, the ’670 Patent Specification, and the cited extrinsic evidence. with the ordinary and customary meaning which does not include limiting SIB1 to an ordinary legacy SIB and excluding MTC specific SIBs or SIBs intended for MTC devices. In addition, we need not construe explicitly any other claim term or phrase. See, e.g., Nidec Motor Corp. 868 F.3d at 1017 (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v.

      “would have had a bachelor’s degree from an accredited program in electrical engineering, computer engineering, computer science, or equivalent training, and at least two years of professional experience relating to wireless communication technology” and “[l]ack of professional experience can be remedied by additional education, and vice versa.” Pet. 15–16 (citing Ex. 1003 ¶¶ 19–21). Patent Owner does not dispute Petitioner’s definition. See generally PO Resp. We find that “at least” in Petitioner’s formulation of the level of skill in the art is vague and open-ended. Otherwise, we adopt Petitioner’s definition of a person of ordinary skill in the art because it is consistent with the level of skill reflected by the ’670 Patent Specification and the prior art of record. slip op. at 14

      “filing date. As explained above, the burden of production shifted to Patent Owner to show that Wallen is not prior art because the ’670 Patent is entitled to the earlier January 20, 2012, filing date of foreign priority application GB1201000. 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. Cir. 1991) (“[T]he applicant must . . . convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention . . . now claimed.” (emphasis omitted)), Ariad Pharm. Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1352 (Fed. Cir. 2010) (en banc) (“[I]t is the specification itself that must demonstrate possession.”). Patent Owner’s arguments fail to meet this burden of production because, aside from addressing a system information block 1, Patent Owner’s arguments do not substantively address how GB1201000 provides written description support for any other limitations of the claimed invention. See PO Resp. 43, 57. 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 foreign priority application GB1201000, the burden of production did not shift back to Petitioner, and,” slip op. at 18

      “primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) including a master information block (MIB).” See Pet. 41–42 (citing Ex. 1003 ¶¶ 70–75; Ex. 1005 ¶¶ 76, 77, 83–84). Petitioner implicitly acknowledges that Wallen does not expressly disclose a physical broadcast channel (PBCH), but relies on Berggren for confirming that the LTE standard specifies that a PBCH carries the MIB. See Pet. 42–43 (citing Ex. 1003 ¶ 74; Ex. 1007 ¶¶ 73–75). According to Petitioner, “a person of ordinary skill in the art would have been motivated to transmit Wallen’s MIB using a PBCH as taught by Berggren.” Pet. 43 (citing Pet. 33–38). In particular, Petitioner asserts that a person of ordinary skill in the art “would have been motivated for Wallen’s LTE system to utilize the LTE standard implementation details taught by Berggren,” and “it would have been predictable and beneficial for Wallen’s user equipment to receive the MIB in the [PBCH], as was standard in LTE.” Pet. 34 (citing Ex. 1003 ¶ 58), 37 (citing Ex. 1003 ¶ 63). According to Petitioner, “the combination is nothing more than ‘the predictable use of prior art elements according to their established functions.’” Pet. 38 (citing KSR, 550 U.S. at 417). Based on the entire record developed during trial, we are persuaded by a preponderance of the evidence that Petitioner provides sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to modify Wallen’s broadcast MIB with Berggren’s teachings of using a PBCH for transmitting broadcast MIBs.

And having studied the intrinsic record of the ’153 patent, we are in accord. But, we decline to further limit the construction of “TPC command accumulation” in the manner proposed by either party––i.e., (1) each TPC command adjustment must be summed to cumulatively affect transmission power (as proposed by Petitioner) or (2) a TPC command value must be added to an integrator.

      “offers nothing to suggest that its card information ‘tells you’ where to store the fingerprint data.” ASSA ABLOY AB, 2025 WL 3134960 at *3. Reversing our determinations as to Hsu, the Court found that the testimony of Petitioner’s declarant, Mr. Lipoff, “merely confirms the associative link between the card information and the biometric data. Still missing is any non-conclusory testimony that Hsu’s card information determines the memory location of the biometric data.” Id. at 8. Therefore, on remand, a central question is whether Petitioner has shown sufficiently that Tsukamura cures this deficiency. Petitioner has not done so. In the Petition, Petitioner relies on Tsukamura for teaching a specific location for storing fingerprint data. See Pet. 75 (stating that “Tsukamura’s index number specifies the physical memory location in the memory”). Petitioner argues that “[t]hus, Tsukamura discloses defining, dependent upon the “index number N index,” a memory location for storing a biometric signature (e.g., a fingerprint template), i.e., ‘a memory location is specified by the card information.’” Id. at 75–76 (citing Ex. 1006 ¶ 215). In support, Petitioner’s declarant, Mr. Lipoff, testifies that “[i]f the Tsukamura implementation were used for Sanford-Hsu database, each user/account number would specify a different entry (index number) in the database.” Ex. 1006 ¶ 394. Tsukamura’s index number N index does not teach or suggest much more than Hsu’s using “an account number or employee number, to access a stored there during an enrollment procedure.” Compare Ex. 1004, code (57), with Ex. 1005, 4:7–11. That is, both references arguably teach defining, i.e., setting or establishing, a certain location in a database for biometric data. For example, as described above, Tsukamura’s fingerprint template Temp is stored in flash ROM 35 at a defined index number N index in the database. Id. 4:7–11, 50–54. However, neither Petitioner, nor Mr. Lipoff, persuasively explain how or why Tsukamura’s fingerprint template Temp, stored at index number N index, is commensurate with “means for defining, dependent upon the received card information, a memory location in a local memory external to the card” as recited in claim limitation 13[C].

Cir. 2019). The parties do appear to disagree on the meaning of “trigger,” however. Although neither party actually identifies that term as needing interpretation and neither party actually provides a claim construction analysis to support its respective position, the parties do dispute whether the evidence presented shows a “trigger,” both presumably giving that term its plain and customary meaning. In other words, while both parties appear to agree “trigger” carries its plain meaning, in application, the parties’ dispute regarding the particular limitations including that term appears to turn, not over what the evidence discloses, but only on whether the disclosure satisfies the plain meaning of “trigger” (see infra § II.E.2). Accordingly, while we apply the plain meaning of “trigger” in this proceeding, and in doing so, we address which party has properly applied the plain meaning and, in doing that, we address the scope properly afforded to “trigger.” That analysis, however, is done below in the context of the limitation in which this issue arises (see id.).” slip op. at 8

      “has now been developed, and in view of both parties’ arguments, we find Petitioner has persuasively shown that modifying Ono’s peripheral device (i.e., communications module 44) to include an input device/physical actuator like the one described for Ono’s remote controller 69 to control the display of image data from a particular user’s computer would have been obvious to a skilled artisan at the time of the invention. More specifically, Petitioner has shown persuasively Ono shows that the use of an input device/physical actuator to send a signal that causes a participant’s computer to transmit and control the image data presented on a shared display in an image display system was a known technique (see Ex. 1005 ¶¶ 7, 44–48, 66– 71, 77–78, 80–89, 144, Figs. 3, 6, 8, 9; Ex. 1002 ¶¶ 85–100, 121–127) and available location for such an input device/physical actuator to initiate the transmission of data (see Ex. 1007 ¶¶ 6, 18, 20, 22–23, 26, 28, 46, Fig. 1; Ex. 1002 ¶¶ 92–100). Petitioner has also persuasively shown that a skilled artisan recognized benefits to giving a participant the ability to locally control the display of their computer’s image data. See Ex. 1002 ¶¶ 87–91; Ex. 1008 ¶¶ 4, 19–20, 27–28; Ex. 1009 ¶¶ 10–13, 39–10, 70–72. When Ono and Corbett are considered together as a whole from the perspective of a skilled artisan, therefore, it is clear that applying a similar input device/physical actuator to Ono’s peripheral device would have been recognized to result in the benefit of providing a participant with the same ability to send a signal that causes a participant’s computer to transmit and control the image data presented on a shared display from their computer within an image display system. As a result, a motivation has been established because the combination is an application of a known technique to derive a known benefit using prior art elements according to their established functions.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

      “that, from their perspective, the plain meaning of the term “trigger” does not exclude intervening steps between a user’s action on an input device and the ultimate transfer of the user selected arbitrary media content. Pet. Reply 11– 12 (indicating that “trigger” encompasses “a process that begins with and thus is triggered by a user pressing a button followed by an ‘image transfer’ from a PC to a projector”). For its part, Patent Owner maintains (at least implicitly) that intervening steps are excluded from the plain meaning. Neither party addresses with more specificity why, or why not, the scope of “trigger” supports their positions, however. Having now the complete record before us, we find that out preliminary assessment was wrong because the plain meaning of the term “trigger” does not exclude intervening steps between the cause-and-effect relationship of the trigger and the result it is intended to cause. Take, for example, a simple gun. Pulling the “trigger” to fire a gun necessarily includes intervening steps to occur: the trigger releases a hammer that, in turn, contacts a blasting cap within a bullet casing, which is what actually causes the gunpowder to ignite (i.e., fire) and expel the bullet. And there is no evidence in this record to suggest that this customary understanding of the word “trigger” is any different in the electrical arts, other than the trigger and result are generally electrical in nature, rather than mechanical. We find no clear disavowal of claim scope within the intrinsic record of the ’951 patent to indicate that the term “trigger” was intended to be understood any differently to exclude any intervening steps between a user’s action on an input device and the resulting transfer of user selected arbitrary media content. intervening steps would exist because the input device does not actually do the transferring of the media content; instead, the claims recite the transferring is “from the transmitter to the wireless communications network and [then] to the base node.” See Ex. 1001, 11:3–48, 27:62–28:1 (claim 1), 28:62–67 (claim 9), 29:42–46 (claim 16), 30:36–44 (claim 21) (emphasis added). A skilled artisan would have recognized that there would be intervening steps between the input device being acted upon and the content being displayed by base node’s display. See Ex. 1083 ¶¶ 11–12. In the claims, the input device is analogous to a gun’s trigger, the user carrying out a user action on the input device is analogous to pulling a gun’s trigger, and the transfer of user selected arbitrary media content is analogous the gun expelling a bullet. In both cases, there can be, and usually are, intervening steps, moreover, in both cases, inadvertent things can happen that may prevent the intended result (e.g., in the case of a gun, the hammer can jam; in the case of an input device, a connection can be rejected). Nevertheless, in both cases, the trigger is the thing that initiates an automated process that leads to a particular result, unless a conditional error occurs.” slip op. at 31
