      “have had a bachelor’s degree in computer science, computer engineering, electrical engineering, human-computer interaction, or a comparable field and at least two years of professional experience in the design and development of graphical user interfaces (GUIs), human-computer interfaces, or equivalents thereof. Pet. 4 (citing Ex. 1003 ¶ 22). Petitioner’s declarant, Loren Terveen, Ph.D., testifies that “[s]uch experience could be obtained through research and study in a graduate program or through comparable exposure through industry employment, and additional years of experience could substitute for the advanced-level degree.” Ex. 1003 ¶ 22. Patent Owner agrees with this definition. PO Resp. 13 (citing Dec. 5). As Petitioner’s description of a person of ordinary skill appears commensurate with the subject matter before us, we apply Petitioner’s definition for purposes of this Decision. Also, the level of ordinary skill in the art can be evidenced by the references cited, and we find it commensurate with the cited references in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).” slip op. at 5

      “according to the Phillips standard.” Pet. 4. Patent Owner contends that under the plain language of claim 1, the “one or more criteria” is satisfied when a “movement parameter” of “the second input” is detected to be “above a movement threshold.” PO Resp. 14. Patent Owner contends that under the plain language of claim 27, the “second one or more criteria” is satisfied when “a duration parameter” of the “second input” is detected to be “above a duration threshold.” Id. at 15. Patent Owner contends that the plain language of limitations [1j] and [1k] requires an operation capable of detecting a second input by a second contact that includes movement across a display in a direction, determining whether the second input meets or does not meet the recited criteria, and triggers performance of each of the corresponding display actions as appropriate. Id. at 15–19. Patent Owner 15. Id. at 21–23. Patent Owner contends that the plain language of limitations [27d]–[27f] recited in claim 27 require an operation that enables the device to detect a second input by a second contact that includes movement across the display in a direction, determine whether the second input meets or does not meet the two recited criteria, and trigger performance of each of the recited display actions as appropriate. Id. at 19– 20. Patent Owner contends that for “the second input” recited in limitations [1j] and [1k], “the second input” must be detected in the same operational context. Id. at 23–24. In particular, Patent Owner contends that limitations [1j] and [1k], and similar limitations recited in claims 15 and 27, “require a single, common contact event as the starting point of the claimed logic operations.” Id. at 24; see id. at 25–26. We do not need to determine whether Patent Owner’s proposed constructions are correct, because under either Petitioner’s or Patent Owner’s proposed constructions, we find that the prior art would have rendered all challenged claims obvious as discussed below in our patentability analysis.” slip op. at 6

      “at 418; see also id. at 421 (“A person of ordinary skill is . . . a person of ordinary creativity, not an automaton.”). Patent Owner’s contention and the supporting testimony of Dr. Madisetti does not address Shiplacoff’s teaching of using a gesture, such as Shiplacoff’s flick gesture, to return to launch screen. We agree with Petitioner and Dr. Terveen in finding that Shiplacoff’s disclosure that “returning to the launch screen . . . is performed by performing a gesture” (Ex. 1004 ¶ 99) such as a flicking gesture (Ex. 1004 ¶¶ 126, 129; Ex. 1023 ¶ 13) teaches using a flicking gesture to return from home screen to launch screen. See Pet. 16, 22–24; Ex. 1003 ¶¶ 52–53, 59; Ex. 1023 ¶ 13; Reply 7–10. Because Dr. Terveen’s testimony is consistent with and supported by the teachings of Shiplacoff as a whole (in contrast to that of Dr. Madisetti), we credit the testimony of Dr. Terveen in finding that using a gesture to return from home screen to launch screen as taught by Shiplacoff, where the gesture is a flick gesture as taught by Shiplacoff, yields the predictable result of using a flick gesture to return from home screen to launch screen.

      “articulate why a person of ordinary skill in the art would have used Shiplacoff’s flicking gesture to switch from full screen mode to the launch screen. PO Resp. 47–49. Petitioner contends that Shiplacoff’s swipe up gesture teaches limitation [1j] by including a movement parameter above a movement threshold. Pet. 17–23. Petitioner contends that Shiplacoff teaches that a user can perform another gesture to return to the home screen. Id. at 23. Petitioner contends that when a gesture different from the swipe up gesture is used to return to the home screen, a person of ordinary skill would have used a flicking gesture because the flicking gesture has a different movement parameter than the swipe up gesture, namely, a movement parameter that does not meet the movement threshold. Pet. 23– 24 (citing Ex. 1004 ¶¶ 99–102, 167; Ex. 1003 ¶¶ 60–61). We agree with Petitioner for the reasons given in the Petition and as discussed above. We reiterate that using a gesture to return from home screen to launch screen as taught by Shiplacoff, where the gesture is a flicking gesture as taught by Shiplacoff, yields the predictable result of using a flicking gesture to return from home screen to launch screen. Ex. 1023 ¶ 13; Ex. 1003 ¶¶ 52–61; KSR, 550 U.S. at 416. We disagree with Patent Owner’s contention that Shiplacoff teaches away from using the flicking gesture to switch from full screen mode to the launch screen because, according to Patent Owner, Shiplacoff already uses the flick gesture to perform scrolling in full screen mode. PO Resp. 49–52 the same gesture in a given mode can be assigned to different functions depending on where, when, and how the gesture is input by the user, as discussed above. Reply 11–12 (discussing Shiplacoff’s teaching of associating the same tap gesture with different functions depending on where the tap occurs), 13–14 (discussing Duarte’s teaching of associating both a drag gesture and a scrolling gesture to the same mode). Ex. 1023 ¶¶ 16–19. We agree with Petitioner and Dr. Terveen, that based on the teachings of Shiplacoff (and, by incorporation, Duarte), a person of ordinary skill in the art would have recognized that a flick started in area 102 or near an edge of screen 101 and continuing onto screen 101 would be distinguished from a flick entirely within screen 101 based on location, and would perform a different function. Ex. 1023 ¶¶ 18–19. We also agree with Petitioner and Dr. Terveen, that Duarte teaches associating a gesture with one function when a modifier key is not pressed, and associating the same gesture with a different function when the modifier key is pressed, such that a flick performed when the key is not pressed would perform one function such as scrolling and a flick performed when the key is pressed would perform another, such as changing the display mode. Reply 15 (citing Ex. 2003 ¶ 64; Ex. 1023 ¶ 20). We agree with Petitioner that Shiplacoff does not teach away from using a flicking gesture to change from full screen mode to home screen because it “does not criticize, discredit, or otherwise discourage investigation into the invention claimed.” Reply 10 (quoting Depuy Spine, 567 F.3d at1327).” slip op. at 25

      “We agree with Petitioner. Lemay Web discloses that the style settings of width, height, pause, and repeat for the pocket watch images can be changed by changing the values for width, height, pause, and repeat in the HTML file. Ex. 1004, 89–90. This results in changing the size, duration, and frequency of the display of the multiple pocket watch image objects without changing the image files or the Java applet. Id. That is, the 12 image objects of Lemay Web can be uniformly formatted by applying and altering the style settings of the HTML file, which is stored separately from the image objects and the Java applet. Id. at 88– 89. In our Final Written Decision, we wrote that “Lemay Web discloses that the image files that are displayed as the animation object are separate from the HTML.” Ex. 1004, 88–89.” Dec. 22. The Federal Circuit wrote that “how the Board evaluated what constitutes separateness in the prior art software is less than clear.” Opinion, 13 n.7. To be clear, the animation of Lemay Web comprises 12 different pocket watch image objects. Ex. 1004, 89. The HTML file that contains the style settings for the 12 different pocket watch image objects is stored separately from the 12 different pocket watch image objects. Id. at 88–91. The style of the 12 different pocket watch image objects can be altered by changing the values of the style settings in the separate HTML file, thus allowing the style to be uniformly applied to each of the associated 12 pocket watch image objects when the pocket watch image objects are created on the web page. Id.; see Ex. 1030 ¶¶ 28–29; Dec. 21–22. In conclusion for issue (B), we find that Lemay Web teaches applying the style located in the separate HTML file to the pocket watch image objects when creating the pocket watch image objects on the web page. Therefore, Lemay Web’s style is “defined separately from any single object” as claimed. Because Lemay Web’s style can be applied to one object and more than one object and Lemay Web’s style is defined separately from any single object, we find that the prior art combination teaches limitations 1(c) and 1(g) under the proper construction of “style.”” slip op. at 12

      “What you see in the bottom right is an excerpt from the Lemay Web book . . . [y]ou can still use the Java applet just by putting this applet code into your HTML file. So this shows the animator class is going to be run within height or how big a window within the browser should be allocated in this applet. You can . . . tell the animator class how long to pause in between each image. So that’s a style that’s being applied to all of the multiple images that make up this animation. Ex. 2029, 746:23–747:7. Patent Owner then asked GoDaddy’s expert “for each unique animation you want to create with this animator class that’s shown here, you’re going to have to have a unique set of HTML code with the settings along with any of the images you’ll want to associate with the animator class, right?” Ex. 2030, 793:7–11. GoDaddy’s expert testified, with reference to Exhibit 2027, 80, that “Yeah. I’m not a hundred percent sure I understand your question, but yes, if you had six animations on a page, for example, you’d have six blocks of markup that looked like the markup at the bottom right of that slide, starting with applet.” Id. at 793:12–16. In addressing Patent Owner’s question about “each unique animation,” GoDaddy’s expert provided a hypothetical example of a web page having six animations, and explained that the six animations have six blocks of markup. Ex. 2030, 793:13–16. We find that this testimony means that if a web page has six unique animations, then for each unique animation, a corresponding HTML file contains the style settings for the image objects of that animation, such that the “six animations on a page . . . have six blocks of markup.” Id. We find that the subsequent testimony of GoDaddy’s expert cited by Patent Owner is consistent with the expert’s initial testimony that Lemay Web’s style is “applied to all of the multiple images that make up this animation.” Ex. 2029, 747:5–7. We also find that the subsequent testimony is consistent with and supported by the disclosure of Lemay Web, which teaches that an animation has a set of image files and is added to a Web page using the Animator applet. Ex. 1004, 88 (“[Y]ou’ll learn just enough about Java applets to set up animation on your Web page. . . . To create animation using Java and the Animator applet, you’ll need . . . [a] set of image files . . . that make up your animation.”); see id. at 88–91. That is, Lemay Web, consistent with the testimony of GoDaddy’s expert, discloses that the style settings for the animation of the pocket watch in the HTML file are uniformly applied to the 12 pocket watch image objects. Id. at 88–91.” slip op. at 17

      “We agree with Petitioner. The Board and Petitioner understood the meaning of “or” in the phrase “one or more objects” in Patent Owner’s proposed construction of style as meaning that “a style . . . can be associated with just one object.” Dec. 22; see Reply 4–5. The Federal Circuit “ultimately conclude[d] that Express Mobile’s proposed construction, with ‘or’ properly interpreted,” means “that the claimed ‘style’ must be capable of being applied to both one and more than one ‘object,’” and “remand[ed] for further proceedings in view of the correct claim construction.” Remand Opinion 13. In doing so, the Federal Circuit stated that “[i]t may be that under the correct claim construction, the Board finds that Lemay Web teaches the claimed ‘style’; however, that is still an open fact question for the Board to decide in the first instance.” Id. at n.6.

      “We agree with Patent Owner (PO Resp. 13) that when Ording refers to user interfaces that are “intuitive and transparent,” “transparent” in that context does not mean optically transparent but something readily understandable, like the preceding word “intuitive.” That makes more sense in context. Patent Owner’s expert, Dr. Mahon, explains that Ording’s paragraph 28, where the phrase “intuitive and transparent” is found, is not concerned with optical transparency, but with increasing user satisfaction with portable devices by offering multifunctional operations on user interfaces based on finger input. Ex. 2012 ¶ 54. Neither Petitioner nor Dr. Cockburn explains why “transparent” in that context should mean optically transparent. We credit the testimony of Dr. Mahon, and reproduce paragraph 28 of Ording below: The various applications that may be executed on the device may use at least one common physical user interface device, such as the touch screen. One or more functions of the touch screen as well as corresponding information displayed on the device may be adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch screen) of the device may support the variety of applications with user interfaces that are intuitive and transparent. Ex. 1006 ¶ 28.

      “The Zlider widget already is the least intrusive in the form as disclosed in the Ramos Paper/Ramos Video, placed off to the side of image content, not above and overlapping with image content. Petitioner’s semitransparency solution is for a self-created problem that otherwise does not exist, i.e., blocking the image by placing the Zlider widget directly over image content in Ording’s device. This is not reasoning with rational underpinning for making the Zlider widget partially semitransparent. Even assuming that the Zlider widget is properly placed directly over a camera image, making the Zlider widget semitransparent does not solve the intrusion problem, because the image and the Zlider widget may obscure each other, as shown in these illustrations provided by Patent Owner: [The illustrations show interference between a semitransparent Zlider widget and an underlying image] In its Reply, Petitioner asserts that it would have been well within the skill level of one of ordinary skill in the art to make adjustments to address a problem caused by such obscuring, such as by making the Zlider widget more visible as shown below: [The illustration shows one way Petitioner asserts one of ordinary skill in the art may apply to solve the obscuring issue (Reply 5–6)] Petitioner’s argument is misplaced. Although there may be graphic display techniques one of ordinary skill in the art may adopt to reduce the visibility problem if the Zlider widget were moved to directly above the image content as Petitioner proposes, that does not cure the problem of lacking a reasonable motivation to place the Zlider widget of the Ramos Paper/Ramos Video directly over image content. Still, there is the least obscuring and the least intrusion with the Zlider widget remaining where it is shown to be in the Ramos Paper/Ramos Video, side-by-side relative to the image content. It is irrational to make a modification that creates a problem, solely on the basis that a solution may be available to reduce the severity of the problem. Indeed, such a strained rationale shows that hindsight has played a part on Petitioner’s contention that a person of ordinary skill in the art would have put the Zlider widget over content as required by the claims.” slip op. at 30

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.

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.”). On the record before us, we do not agree that the ’171 Patent is entitled to a filing date earlier than Jan. 11, 2021. In particular, we do not agree that PCT ’199 describes the invention in enough detail such that a person of ordinary skill in the art could conclude that the inventor was in possession of the invention as of the March 4, 2016 filing date. The disclosures of PCT ’199 cited by Patent Owner to show written description support show: (1) transmission packets for multi-user uplink data, which includes padding such that multi-user upstream data transfers from each resource terminate at the same time (see Ex. 1012 ¶¶ 17–21); (2) performing padding on a trigger frame that triggers multi-user simultaneous transmission, where the trigger frame includes AID information of the performing preset padding before the FCS field of the trigger frame according to one embodiment (see Ex. 1012 ¶ 136, Fig. 20); and (4) inserting redundant AID information prior to the FCS field of the trigger frame, according to another embodiment (see Ex. 1012 ¶ 136, Fig. 20). PCT ’199 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a frame for allocating resource for uplink (UL) multi-user (MU) transmission to one or more terminals that includes the AID field set to a value related to a first padding field, when the padding field is included in the frame. In particular, we discern no disclosure that conveys that the inventor possessed the following: (1) an AID field for the MU UL resource allocation frame is set to a value, (2) that the AID field is set to a value related to the padding field, and (3) that the AID field is set to a value related to the padding field, and conditioned on the inclusion of the AID field in the frame. Moreover, to the extent that Patent Owner’s assertions are premised on the PCT ’199’s disclosure of a preset padding being performed before the FCS field of the trigger frame and the disclosure of inserting redundant AID information prior to the FCS field of the trigger frame, we note that these disclosures are directed to two embodiments. See Ex. 1012 ¶ 136, Fig. 20. PCT ’199 does not provide any suggestion that the two embodiments are used together, or that the redundant AID information of one embodiment can serve as a preset padding of the other embodiment.” slip op. at 16

PCT ’199 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a trigger frame indicating uplink transmission for one or more terminals that includes an AID field used to identify whether the trigger frame includes a padding field, and the trigger frame including the padding field when the AID field is set to a specific value. In particular, we discern no disclosure that conveys that the inventor possessed the following: (1) a trigger frame indicating uplink transmission to one or more terminals and including an AID field used to identify whether the trigger frame includes a padding field; (2) the AID field for the trigger frame is set to a specific value, and (3) that trigger frame includes the padding field when the AID field is set to a specific value. Moreover, to the extent that Patent Owner’s assertions are premised on the PCT ’199’s disclosure of a preset padding being performed before the FCS field of the trigger frame and the disclosure of inserting redundant AID information prior to the FCS field of the trigger frame, we note that these disclosures are directed to two embodiments. See Ex. 1012 ¶ 136, Fig. 20. PCT ’199 does not provide any suggestion that the two embodiments are used together, or that the redundant AID information of one embodiment can serve as a preset padding of the other embodiment. On the record before us, we also do not agree that KR ’754 describes the invention in enough detail such that a person of ordinary skill in the art could conclude that the inventor was in possession of the invention as of the March 17, 2015 filing date of KR ’754. The disclosures of KR ’754 cited by Patent Owner to show written description support show: (1) multiplexed terminals over respective channels, (see Ex. 1008 ¶¶ 65–66, Fig. 10); (2) differing the number of AID values in the batch acknowledgment (BA) information field when the number of terminals assigned to each channel differs, setting the length of each multiplexed group ACK differently, and, if necessary, aligning the lengths of the multiplexed group ACKs based on the channel with the longest assigned BA information by adding zero padding or repeatedly inserting BA information (see Ex. 1008 ¶¶ 66–70, Fig. 11); and (3) applying the use of the AID field padding and the use of BA padding in a downlink OFDMA trigger process during multi-user downlink transmission to align the length of the trigger when the AP notifies the terminals assigned to each channel by inserting zero padding or repeating AIDs (see Ex. 1008 ¶¶ 71–72, Figs. 11–12). KR ’754 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a trigger frame indicating uplink transmission for one or more terminals that includes an AID field used to identify whether the trigger frame includes a padding field, and the trigger frame including the padding field when the AID field is set to a specific value. In particular, we do not discern disclosure in KR ’754 that conveys that the inventor possessed the following: (1) a trigger frame indicating uplink transmission to one or more terminals and including an AID field used to identify whether the trigger frame includes a padding field; (2) the AID field for the trigger frame is set to a specific value, and (3) that trigger frame includes the padding field when the AID field is set to a specific value. We find misplaced Patent Owner’s argument that “KR ’754’s discussion about Figure 10 and Figure 11 would have been understood [by a POSITA] as disclosing a padding method used to improve predictability and consistency trigger frame” (Prelim. Resp. 12) because: (1) it addresses uplink transmissions and not a trigger frame indicating uplink transmission to one or more terminals; (2) it does not address that the padding field is included in the trigger frame when the AID field is set to a specific value; and (3) it is unsupported attorney argument regarding the understanding of a person of ordinary skill in the art. Argument of counsel cannot take the place of objective evidence. See Gemtron Corp. v. Saint-Gobain Corp., 572 F.3d 1371, 1380 (Fed. Cir. 2009). We also find misplaced Patent Owner’s argument that “the padding discussed by KR ’754 regarding its Figure 12 embodiment is not limited to downlink transmission and would have been understood by a POSITA as also being used to schedule uplink ones” (Prelim Resp. 14) because: (1) KR ’754 does not provide any suggestion that the same technique can be used for uplink transmission trigger frames; (2) Patent Owner’s argument does not address that the padding field is included in the trigger frame when the AID field is set to a specific value; and (3) Patent Owner’s argument is unsupported attorney argument regarding the understanding of a person of ordinary skill in the art. See Gemtron, 572 F.3d at 1380. For the foregoing reasons and based on this record, for the purpose of institution, we find that the ’186 Patent is not entitled to an effective filing date earlier than April 8, 2019 and find that Kim is prior art. We note that the limitations at the heart of the written description dispute were added in an amendment filed August 9, 2020. See Ex. 1002, 214–21.

      “We do not agree with Patent Owner’s arguments because they are premised on Choi’s teachings as limited to AIDs transmitted via a control frame broadcast as a TIM element.

Chu, Choi, and the testimony of Dr. Ding (Ex. 1003), we are persuaded Petitioner sets forth 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 combine Chu’s teachings with Choi’s use of specific AID or ΔAID values as indicators of the end of meaningful data and the beginning of padding that would allow client stations to reliably determine where the useful content of the trigger frame ends and where optional padding begins, with the benefits of improved parsing efficiency, enhanced synchronization, and reduced likelihood of misinterpreting padding as data as padding.

      “To the extent Patent Owner contends that a person of ordinary skill in the art need not be defined as of the critical date, we disagree. Under Section 103, we must determine “if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains” (emphasis added). “Obviousness is determined from the vantage point of a hypothetical person having ordinary skill in the art to which the patent pertains.” In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). Thus, we define the hypothetical person of ordinary skill in the art as of a time before the effective filing date. To the extent Patent Owner’s argument is that, to testify from the perspective of a person of ordinary skill in the art, one need not have been a person of ordinary skill in the art as of the critical date, we agree. Although one must at least possess ordinary skill in the art to testify from the perspective of a person of ordinary skill, [a]n expert need not have acquired that skill level prior to the time of the invention to be able to testify from the vantage point of a person of ordinary skill in the art.

      “C. Claim Construction The parties agree that no claim terms require express construction. Pet. 10; Prelim. Resp. 2–4. Patent Owner, however, notes that, in related district court litigation, Petitioner has asserted that some claims terms are indefinite. Patent Owner argues that the Petition should be denied because Petitioner has taken inconsistent claim construction positions between the district court and the Board. Paper 14 at 1–3 (citing Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025-00340, Paper 18 at 4 (PTAB Nov. 5, 2025) (informative); Revvo Techs., Inc. v. Cerebrum Sensor Techs., Inc., IPR2025-00632, Paper 20 at 4–5 (PTAB Nov. 3, 2025) (precedential)). Petitioner responds that, in the related district court litigation, the parties have narrowed the claim construction disputes and that Petitioner accords the plain and ordinary meaning to claim terms and no longer asserts that any claim term of the ’077 patent is indefinite. Paper 15 (citing, inter alia, Ex. 1126 (Defendants’ Responsive Claim Construction Brief)). The evidence supports Petitioner’s position because, in the related district court litigation, the defendants agree with the plaintiff (Patent Owner) that certain phrases in the ’077 patent claims should be given their “[p]lain and ordinary meaning” and are “not indefinite.” Ex. 1126, 6 (native page 1). Thus, the record does not show inconsistent claim construction positions that warrant denial under PTAB precedent. See Revvo, Paper 20 at 5 (addressing a situation in which a petitioner advances “different claim construction positions” in district court and at the PTAB). See Realtime Data, LLC v.

Resp. 20. Petitioner, however, points out this change in the Petition and acknowledges that it is after the identified critical date of August 20, 2015. See Pet. 28.

We understand Petitioner to be relying on disclosures in Bharadwaj-Prov059 for prior art teachings for its obviousness contentions. Patent Owner does not appear to dispute that Bharadwaj-Prov59’s disclosures are prior art, arguing instead that it is improper to rely “on matters in Bharadwaj beyond ‘incorporation by reference’ of the Bharadwaj-Prov59.” See Prelim.

      “Additionally, we credit the testimony of Dr. Almeroth, who opines that Kleve discloses that certain restrictions are sent with the request to generate a virtual key. Ex. 1003 ¶¶ 118–123. Specifically, Dr. Almeroth testifies that Kleve discloses that the virtual key “enable[s] the keyless drive system for the appropriate Temporary User during a given rental period.” Id. According to Dr. Almeroth, this “indicates that rental agreement restrictions were sent with the request so that the virtual key could be associated with said restrictions.” Id. (citing Ex. 1004 ¶¶ 39, 68 (“Once the rental period has expired the virtual key may be reset and cleared from the VCS.”)). Dr. Almeroth further testifies that the virtual key in Kleve is always generated after the rental agreement. Id. (citing Ex. 1004 ¶¶ 39 (“[O]nce the Temporary User selects the vehicle, pays the appropriate amount and signs a consent agreement, th[e]n the system may generate a virtual key to distribute to the Temporary User and VCS.”), 68). We do not agree with Patent Owner’s argument that Dr. Almeroth’s declaration testimony contradicts Kleve. See PO Resp. 27–29. Rather, as discussed previously, we find that Kleve’s vehicle owner can set a restriction, such as the rental start period, prior to step 214 in Kleve’s Figure 2 and that such restrictions can be associated with the e-key. We also do not agree with Patent Owner’s argument that (1) Dr. Almeroth’s declaration testimony contradicts his deposition testimony or that (2) Dr. Almeroth “admitted his testimony was wrong.” See PO Sur-Reply 7 (citing Ex. 2030, 27:5–10, 27:21–28:1). In a particular embodiment to which Dr. Almeroth was citing, he noted that the e-key is always generated after the rental agreement. See Ex. 2030, 26:14–20. Then the following exchange occurs: Q. So you use typically and always. So always does not refer to all of the embodiments of Kleve, is that fair? A. I think a person of skill in the art could read Kleve and understand that there are probably multiple ways in which the flow of actions among the parties could occur. And I think thinking about a real world scenario, in most cases you have an agreement before you would generate an eKey, but maybe, maybe not. I don’t -- I don't know that the real world is necessarily cut and dry. So reading -- a person reading Kleve would understand it’s describing embodiments where it’s always the case. That might be a pretty common scenario, but I don't know that it would necessarily be a hard and fast rule in every embodiment or in the understanding a person of skill in the art would have. Id. at 28:3–20. There is nothing in the deposition testimony by Dr. Almeroth that appears inconsistent with his declaration testimony nor does there appear to be the kind of admission touted by Patent Owner. Instead, it is Dr. Malek who takes an overly narrow view of Kleve that appears inconsistent with Kleve’s disclosure when read as a whole. See, e.g., Ex. 2001 ¶¶ 56–57. Therefore, we do not credit or agree with Dr. Malek’s testimony that Kleve teaches away from the concept of a virtual key created with the agreed-upon rental period as a restriction.

      “We have authority to determine whether to institute an inter partes review under 35 U.S.C. § 314 (2023) and 37 C.F.R. § 42.4(a) (2024). An inter partes review may be instituted if “the information presented in the petition filed under section 311 and any response filed under section 313 shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a). Upon consideration of the papers, we determine that the information presented in the Petition demonstrates that there is a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one challenged claim of the ’721 patent.” slip op. at 2

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “the effective filing date of the claimed invention, we consider the level of ordinary skill in the pertinent art at the time of the invention. Graham v. John Deere Co., 383 U.S. 1, 17 (1966). In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citing Custom Accessories, Inc. v. Jeffrey- Allan Indus., Inc., 807 F.2d 955, 962–63 (Fed. Cir. 1986)). “[O]ne or more factors may predominate.” Id. Petitioner argues that one of ordinary skill in the art at the time of the ’721 patent “would have a bachelor’s degree in electrical engineering, computer engineering, computer science, or a similar field, along with two years of experience designing or developing wireless networks, including long-term evolution LTE/4G and 5G new radio (NR) cellular technology.” Pet. 4 (citing Ex. 1003 ¶ 32). Petitioner adds that “[a]dditional education might substitute for some of the experience, and additional substantial experience might substitute for some of the educational background.” Id. at 4–5. Patent Owner at this stage of the proceeding does not provide an alternative definition for a level of skill in the art that one would have had at the time of the ’721 patent or identify any shortcoming in Petitioner’s formulation. See Prelim. Resp. 2. For purposes of this Decision on Institution, we adopt Petitioner’s definition of the level of skill for one of ordinary skill in the art. Pet. 4–5. We view the definition for the level of ordinary skill as consistent with the ’721 patent and the asserted prior art, and we apply it in our analysis below.” slip op. at 6

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededOther

      “Petitioner argues “that no claim terms need be construed to resolve issues of controversy in the present Petition.” Pet. 4. Patent Owner argues that at this stage, “claim construction is not required to resolve any issues.” Prelim. Resp. 2. We determine that no express constructions are needed for us to render our Decision on Institution. See, e.g., Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)) (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’”). Rather, at this stage of the proceeding, we apply the plain and ordinary meaning of the claim terms.” slip op. at 7

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successOther

      “IV. PRINCIPLES OF LAW A claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art. KSR Int’l Co. v. Teleflex, Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of non-obviousness, if present.5 See Graham, 383 U.S. at 17–18. When evaluating a claim for obviousness, we also must “determine whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)).” slip op. at 8
