    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “We find that Petitioner’s description is consistent with the prior art and patent specification currently before us. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself may reflect an appropriate level of skill). For purposes of our Decision, we adopt Petitioner’s definition of the level of ordinary skill in the art as “a Bachelor’s degree in electrical engineering or a similar field, and 1–2 years of experience researching and developing antennas used in RFID applications.” See Pet. 8. In addition, we note that we agree with Patent Owner’s statement that the distinction between the parties’ proposals is not material to any dispute before us and we find that our determinations would be the same under either definition of the person of ordinary skill in the art.” slip op. at 6

      “provide an express construction of the full breadth of a claim term. “The Board is required to construe ‘only those terms ... that are in controversy, and only to the extent necessary to resolve the controversy.’” Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019). As such, we proceed in line with Federal Circuit case law, which “prescribes—deciding only the issues necessary to resolve the dispute before it.” Nichia Corp. v. DSS, Inc., No. 2022-1704, 2023 WL 7211097, at *3 (Fed. Cir. Nov. 2, 2023) (citing Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017)). The Federal Circuit has long recognized that “[c]laim construction is a matter of resolution of disputed meanings and technical scope” and that claim construction may be required in an obviousness context “when the meaning or scope of technical terms and words of art is unclear and in dispute and requires resolution in order to determine obviousness.” U.S. Surgical Corp. v. Ethicon, Inc., 103 F.3d 1554, 1568 (Fed. Cir. 1997). In order to determine whether Petitioner’s obviousness grounds meet their required burden of proof, we need not expressly state the full scope of this claim term. Thus, we are within our authority to proffer a construction that determines the scope of a claim term in a manner sufficient to determine whether the asserted art teaches the claim. In other words, there may be other ways to meet the disputed limitation, but for the purposes of our Decision, it is proper to expressly determine a claim term’s scope only as much as is required to resolve the disputed issues before us.” slip op. at 17

      “In the Petition, Petitioner states that it is unnecessary to construe any claim terms or phrases (Pet. 12–14), but for two phrases in claim 1, Petitioner specifically argues that the prior art teaches or suggests the phrase under each of two alternate meanings (id. at 34–35, 37). In the Institution Decision, we agreed with Petitioner’s primary understanding of these phrases and, as a result, did not reach the alternative contentions. Inst. Dec. 33 n.18, 38 n.21. At trial, Patent Owner states that claim construction is unnecessary to resolve the issues disputed in this proceeding. PO Resp. 6; Tr. 46:4–16.

    • BurdenNot shown unpatentable

      “motivated to add error processing to Garcia’s mobile phone so that it could address errors before transmitting the check image in order “to avoid wasting communications resources and adding delays.” Pet. 42. But, Petitioner does not support this rationale with a persuasive explanation or evidence. Indeed, we assume that Petitioner’s theory is that the error checking at the mobile device would have conserved bandwidth and reduced delay because it would have allowed the mobile device to identify some unsuitable images before they were sent to the payee bank; however, the Petition does not actually include an explanation to this effect. Rather, it simply states that an ordinary artisan would have known that mobile telephone networks (such as that used by Garcia) “are bandwidth and resource-constrained, and that communications over such networks takes time.” Id.; see also Ex. 1002 ¶ 115. However, all networks have bandwidth and resource constraints, and all communications take time, and neither the Petition nor Dr. Mowry explain why these considerations would have been relevant to an ordinary artisan implementing Garcia. Indeed, the Petition next asserts that “Byrne provides the requisite solution to this problem” (Pet. 42), but neither the Petition nor Dr. Mowry identify any problem. For example, Dr. Mowry does not testify that an ordinary artisan would have expected Garcia’s system to consume excessive bandwidth or incur for claim 2). In addition, Petitioner recognizes that the verification process is performed by the payee bank in Garcia, yet does not address the fact that its proposal would apparently shift a portion of the verification process to the mobile phone. See Pet. 40–44. Dr. Mowry’s trial testimony casts further doubt on Petitioner’s rationale for this claim. Dr. Mowry testifies that conserving bandwidth would “potentially” have been one of the goals of an ordinary artisan “depend[ing] on how precious their resource is.” Ex. 2020, 68:12–24. But Dr. Mowry “wouldn’t necessarily characterize [Garcia] as bandwidth intensive.” Id. at 76:13–23. In addition, he disagreed that “in the Garcia system, the motivation would have been to shift it to the client side for the verification,” noting simply that “[t]here are tradeoffs” associated with doing the verification processing on either the client or the server. Id. at 241:22– 242:13. Petitioner attempts to limit the impact of Dr. Mowry’s answers (Pet. Reply 16); however, the fact remains that Petitioner has the burden of proof, and it does not identify persuasive evidence to support its contention. Petitioner’s Reply asserts that these considerations were “particularly important in 2006, when 3G bandwidth was at a premium” (id. at 22 (citing Ex. 1029 ¶ 49)), but neither Petitioner nor Dr. Mowry provide analysis or evidence to support this conclusory assertion. Moreover, the Petition also fails to address whether the proposed combination would have, in fact, conserved communications resources or reduced delays. In Petitioner’s proposed combination, Byrne’s thin client application would be downloaded to Garcia’s mobile phone at each use (which would require communication resources and incur latency), but the Petition fails to address whether the net result of the proposed combination 148:1 (Dr. Mowry agreeing that the impact of downloading the thin client is not discussed in his report). Moreover, Garcia touts the “speed” of its process, stating that its “immediate processing . . . allows the immediate availability in the user’s account” (Ex. 1003, 7:18–8:3), which indicates that an ordinary artisan would not have perceived a problematic delay in Garcia’s system. Petitioner’s attempt to shift the burden to Patent Owner to determine whether or not its purported benefits would be realized (see Pet. Reply 17) is unavailing. In its Reply, Petitioner cites testimony from Dr. Mowry (see Ex. 1029 ¶ 37), but it simply compares the size of a compressed image with the size of a “large” application. This evidence does not outweigh the other evidence above, and it was submitted too late to remedy the Petition. See supra § II.A.; see also Trial Practice Guide 73 (explaining that a 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”). Finally, on this record, we are also not persuaded by Petitioner’s” slip op. at 60

      “would have been motivated to implement Garcia’s application by downloading, onto the mobile device, a thin client application, as disclosed by Byrne. See Pet. 19–25. Byrne touts the benefits of downloading a thin client rather than storing an application on a user’s device (Ex. 1004 ¶¶ 45– 46; see also id. ¶¶ 47–48), and Dr. Mowry testifies that an ordinary artisan would have understood downloading a thin client to be a well-known way of distributing software in the relevant time period and suited for mobile devices (Ex. 1002 ¶¶ 64–65, 70). In addition, Dr. Mowry testifies that a thin client improves security and ease of software maintenance. Id. ¶ 65 (citing Ex. 1004 ¶¶ 46–47); see also Ex. 1033, 140:11–141:2 (Dr. Creusere agreeing that thin clients “dramatically simplif[y]” software maintenance), 143:13–20 (agreeing that security is important for financial data); Ex. 1005 ¶¶ 20–21 (evidence that the general background knowledge in the art identifies security as a concern for remote check deposit).14 In addition, we agree with Petitioner (see Pet. 21–22; Ex. 1002 ¶¶ 66, 72) that an ordinary artisan would have understood such an implementation to apply a known 14 Patent Owner’s argument that security and software maintenance would have instead weighed against the proposed combination (see, e.g., PO Sur-reply 9–10) is untimely because it was not advanced in the Response and is not fairly responsive to the Reply. See supra § II.A; Pet. Reply 15–16 (noting that the Response had not addressed these issues). Moreover, even if this argument had been properly raised, it would not be persuasive because Patent Owner does not identify persuasive evidence to support its position. See, e.g., Icon Health & Fitness, Inc. v. Strava, Inc., 849 F.3d 1034, 1043 (Fed. Cir. 2017) (“Attorney argument is not evidence.”). (Garcia’s mobile phone) with predictable results. We are also persuaded that a person of ordinary skill in the art would have been motivated to implement Garcia’s application such that the application provides a user-interface and controls the image capture device, as disclosed by Byrne. See, e.g., Pet. 22–23. Garcia suggests that the application should perform these functions (see Ex. 1003, 5:1–6:10, 9:19– 10:18), and we credit Dr. Mowry’s testimony that an ordinary artisan would find this desirable (see Ex. 1002 ¶¶ 65, 67). Moreover, the references lend themselves to the combination because Garcia and Byrne both describe remotely depositing a check via the Internet using software on a user’s device that opens an interactive session, and both perform substantially similar steps. See Pet. 22–23; Ex. 1003, 9:21–10:3, 10:10–18, 11:7–15; Ex. 1004 ¶¶ 41, 48, 174–175, 177–178. Finally, Dr. Mowry testifies that the ordinary artisan would have had a reasonable expectation of success in implementing the combination, and he provides supporting analysis and evidence. Ex. 1002 ¶¶ 68–72; see also Ex. 1029 ¶¶ 38–39. We credit this testimony from Dr. Mowry because it draws reasonable inferences and is supported by the cited evidence.” slip op. at 25

Petitioner argues each of Cooper and Baldwin teaches each limitation of each independent claim, and Petitioner presents its combination of references separate from its comparisons of Cooper and Baldwin to the claims, without clearly stating how the references are to be combined or how those combined teachings satisfy particular limitations.

      “Patent Owner contends, and we agree, that Cooper does not teach that its receiver identifies which of two streams is expected to result in a lower latency, as required by limitation [1d]. PO Resp. 36–52. Where Cooper describes receiving a multiplexed composite signal, Cooper teaches always identifying the normal mode packet stream for decoding when it is available, without regard to latency, and identifying the robust mode packet stream for decoding only when the normal mode packet stream is not available, such as when normal mode packets are lost. E.g., Ex. 1004, 7:8–8:28. In fact, it would be inconsistent with Cooper’s teachings for the receiver to select the robust mode packet stream when the normal mode packet stream is available: Cooper teaches that “[u]nder normal conditions, the error signal is not active on the error signal line E. In response, the selector 230 couples the normal mode packet stream to the multi-standard decoder 240, and the multi-standard decoder 240 begins to generate the content representative signal from the normal mode packets . . . .” Ex. 1004, 7:32–37 (emphasis added). Although Cooper also teaches that its receiver can decode the robust mode packet stream to avoid “undue delay” “at the beginning of any broadcast or channel change,” we find that Cooper does so only when the normal mode packet stream is not available. Ex. 1004, 17:23–45; see also Ex. 1004, 3:1–3. Specifically, Cooper states that “at the beginning of any broadcast or channel change,” there is a period of time (i.e., Tadv ) when the receiver’s delay device 220 is being filled. Ex. 1004, 17:23–26 (emphasis added). Cooper explains that waiting until delay device 220 is full would cause “undue delay when a receiver is switched on or a channel is changed.” Ex. 1004, 17:26–30. To address this delay, Cooper’s receiver decodes the robust mode packet stream, which “is immediately available,” so that a video signal can be presented until “the normal mode packet stream becomes available,” at which point the receiver switches to decoding the normal mode packet stream. Ex. 1004, 17:30–42. Consequently, we find that Cooper teaches that, at a channel change, its receiver receives (and decodes) the robust mode packet stream until it receives the normal mode packet stream. We disagree with Petitioner’s contrary argument that Cooper’s receiver receives both streams in this situation (see Reply 4–16), and, at a minimum, Petitioner has not persuasively shown that Cooper teaches or suggests this (see Ex. 2015, 82:22–85:13 (describing different scenarios but acknowledging that “Cooper doesn’t really illuminate either of these”)). Further, Cooper’s description of Figure 3 is consistent with our understanding of Cooper description of a channel change. Specifically, that portion of Cooper states: Time t0 may represent the time when the receiver is turned on, or when a user specifies a new content source to receive. During the time, Tadv, between t0 and t4, robust mode packets “a” to “j” are loaded into the delay device 220, and normal mode packets, designated “0” through “9” are received. At time t4, the normal mode packet “A” becomes available from the demultiplexer 210 and delayed robust mode packet “a” becomes available from the delay device 220. Under normal conditions, . . . the selector 230 couples the normal mode packet stream to the multi-standard decoder 240, and the multi-standard decoder 240 begins to generate the content representative signal from the normal mode packets, as described above. This is illustrated by the cross hatching 301 in the normal mode packets “A” through “G”. Ex. 1004, 7:24–39. Cooper includes this description in order to explain its typical operation as well as to illustrate the relative timing of the robust mode packet stream and the normal mode packet stream. See Ex. 1004, 7:24–25, 7:40–8:28. This passage teaches that normal mode packets designated with capital letters (e.g., “A”) are displayed after time t4 under normal conditions; however, it does not address which (if any) packets are displayed between time t0 and time t4. As a result, we understand this passage of Cooper to indicate that “0” to “9” are simply placeholders, which” slip op. at 13

      “Having considered the parties’ arguments and evidence, we are persuaded that Copeland discloses this limitation. Copeland analyzes a flow’s statistics (including start time, end time, number of bytes, and number of packets) “to determine if the flow appears to be legitimate traffic or possible suspicious activity” and computes a concern index for the flow if it appears suspicious. E.g., Ex. 1007, 3:31–35, 7:38–67, 16:36–17:5. We find that Copeland’s concern index qualifies as a “badness factor for the flow . . . [that] provides an indication of whether the flow is exhibiting undesirable behavior,” as required by claim 9. E.g., Ex. 1007, 3:31–40, 4:30–33, Fig. 1 (identifying “‘bad’ flow(s)”). As Dr. Jeffay explains, an ordinary artisan would have understood that suspicious activity (such as a probe or network attack) is undesirable behavior. Ex. 1003 ¶¶ 211–212.

      “on an integrated circuit package substrate for connecting with a printed circuit board.” PO Resp. 9–12; Sur-reply 1–2. Petitioner disagrees. Reply 6. But, because we find that Petitioner has shown that Chin suggests implementing its invention in an IC9 package substrate as Patent Owner’s proposed construction would require (infra § III.D.2.), we need not resolve this dispute. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Patent Owner advocates limiting the scope of this claim term to include only the contact pads in a particular location (i.e., the PCB-side of the IC package substrate),10 but the intrinsic record does not support importing such a limitation into the claim. Patent Owner identifies (and we perceive) no passage in the intrinsic record that redefines the term “contact pads” or disavows part of its scope. See Thorner v. Sony Computer Ent. Am.

      “we agree with Petitioner that Chin explains that its “concepts apply equally to an integrated circuit package substrate.” Pet. 22. In particular, we find that Chin discloses an IC package substrate. See Ex. 1004, 1:61–62 (referring to “a substrate used inside a BGA package”); see also Ex. 1003 ¶¶ 28–30 (Dr. Choi explaining that a BGA is a type of IC package). We credit Dr. Choi’s testimony on this point because it is logical and supported by cited evidence. See, e.g., Ex. 1014, 45;12 Ex. 1016, 5–7. We are also persuaded that Chin expressly suggests implementing its invention in an IC package substrate. Chin begins its description by stating that “[t]he present invention relates generally to the design and fabrication of printed circuits and multi-layered substrates.” Ex. 1004, 1:7–8 (emphasis added). Chin also states that its invention “is illustrated by way of example, and not by way of limitation,” in its figures. Ex. 1004, 3:26–27. Similarly, Chin’s final paragraph states that alternative implementations “will be apparent to those skilled in the art,” and it states that “semiconductor implementations . . . are contemplated as within the scope of the present invention” as they use “similar layered printed circuit routing techniques.” Ex. 1004, 5:54–6:10. Moreover, as background for its invention, Chin addresses problems encountered as signal speed increases and explains that “excess parasitics that limit the bandwidth” are caused by an impedance mismatch between landing pads and their associated interconnect conductors. Ex. 1004, 1:35–56. Chin then states: One example is the use of a ball-grid-array (BGA) package in a multi-gigahertz printed circuit board. The landing pads of current state of the art BGAs are typically 25–30 mils in 12 Unless otherwise noted, our citations refer to page numbers added to an exhibit by Petitioner or Patent Owner rather than the document’s native page numbers. diameter, which is significantly larger than the typically 5 mil microstrips used in interconnecting conductors. Another example is a substrate used inside a BGA package. Typical solder ball landing pad sizes for current technology BGA substrates are on the order of 20–25 mil, significantly larger than the typically 3 mil traces used in microstrip interconnects. Ex. 1004, 1:56–65 (emphasis added). Accordingly, given the context provided by Chin (see Ex. 1004, 1:7–8, 5:54–6:10), we find that a person of ordinary skill in the art would have understood this passage (see Ex. 1004, 1:61–65) to suggest applying Chin’s disclosure to an IC package substrate.

Dr. Brogioli acknowledged that he never even analyzed whether the features of Walker that he argues are not enabling are required in the claims of the ’868 patent. Ex. 1032, 84:1-85:22 (testifying that he did not recall performing an analysis about whether the claims of the ’868 patent required allowing users to edit different parts of the same file at the same time, user collaboration, concurrency among user actions and editing, or locking a document). Moreover, other than pointing to the allegedly deficient teachings of Walker itself, Dr. Brogioli cites to no evidence of record in support of his testimony that a POSITA would not have a reasonable expectation of success in implementing Walker.

      “we are not persuaded by Patent Owner’s claim construction position that the claims require the virtual server to transmit information about files locally stored on the client device (in addition to virtual server files) as part of the fourth claim element. With regard to the claim language, we agree with Patent Owner that “the one or more files associated with the particular user storage account” recited in the fifth claim element finds antecedent basis in the prior recitation of “information relating to one or more files associated with the particular user storage account” in the fourth claim element. By its plain language, what this means is that at least some of the “information” that is transmitted from the virtual server under the fourth element must be related to the “userselected file” that is subsequently uploaded from the client device under the fifth element. Cf. Yamaha Corp. v. ESS Tech., Inc., 82 F.3d 435, 1996 WL 146499, *3 (Fed.

Thus, contrary to Petitioner’s arguments, we are not of the view that files referenced in the fourth and fifth elements are completely “distinct.” But this does not necessarily imply, as Patent Owner suggests, that the virtual server must already be in possession of information relating to locally stored files at the point of the transmitting step of the fourth element and prior to the uploading step of the fifth element.
