    “Turning to the substantive issues, we find the District Court’s “mirror tracking mode” construction to be well-reasoned and supported by the record, and we therefore adopt that construction and its reasoning. As the District Court points out, both the “double the distance” and “same size” aspects of its construction are expressly discussed in the ’109 patent, which is incorporated in the ’110 patent. See Ex. 2008, 16 (citing Ex. 1021, 2:5–27, Figs. 5A, 5B), 40 (citing “same reasons set forth regarding the term ‘it appears to mimic a reflection of a mirror’” in support of construction of “mirror tracking mode”).

    “Post-institution, Patent Owner invites us to construe limitation 1[f]’s recitation of “mirror tracking mode” and limitation 1[c]’s recitation of “adaptive transformation mapping.” PO Resp. 9–14. Regarding the latter, Patent Owner explains that “[i]n the District Court Litigation, ‘adaptive transformation mapping’ was construed as ‘continuously variable transformation mapping’ and ‘transformation mapping’ was construed as a ‘selected set of image transformations.’” Id. at 14 (citing Ex. 2008, 14, 37; Ex. 2013 ¶¶ 25, 27).

    “persuasively address limitation 1[f]’s “mirror tracking mode.” In particular, Petitioner does not address persuasively the requirement, as explained in Section II.B above, that mirror tracking mode involves processing camera-captured images in a way that “maintains roughly the same size regardless of the user movement.” At odds with this requirement, Petitioner founds its case on an assertion that “Haan teaches the claimed mirror tracking mode” because “if the viewer is within 35 cm of the camera, a tracking mode is entered, applying resizing transformation.” Pet. 44 (emphasis added) (citing Ex. 1005 ¶¶ 75–76, 80–82, 90–94, 97; Ex. 1003 ¶¶ 205–210). The resizing transformation Petitioner references actually involves magnifying the user’s image by an amount that changes based on the user’s position relative to the camera, quite the opposite of maintaining image size regardless of the user movement. Ex. 1005 ¶¶ 75–76, Fig. 8. Thus, Petitioner’s initial position is unpersuasive. Petitioner’s shift to Haan’s “reflective mirror mode and conventional mirror period in the dual mode” is also unavailing. Reply 8. Consistent with Patent Owner’s arguments, Petitioner does not provide persuasive evidence that these operating states of Haan’s device involve any processing of camera-captured images. Sur-reply 13–14. To the contrary, Haan suggests that anytime its device provides an unmagnified image, it comes from a reflection off a physical reflective surface. See, e.g., Ex.1005 ¶ 76 (“This can be done for instance by using the device as a simple mirror, i.e. not displaying an image on the display device, but using the device in the reflective mode.”) (emphasis added), ¶ 92 (“a simple reflective mode, to act as a mirror”), ¶ 29 (“for a first range of positions, no image is displayed, whereby the reflective layer acts as a mirror, and for a second range of positions, the recorded image is displayed.”) (emphasis added). We also find unpersuasive Petitioner’s Reply arguments based on Haan’s disclosure of smoothly transitioning from “using the device as a simple mirror” (i.e., using a physical reflecting surface) to displaying a magnified image. Reply 11 (citing Ex. 1005 ¶¶ 76, 80). To the extent this may establish a point around the transition at which Haan’s system displays an image with relatively little magnification, it does not establish that Haan teaches, suggests, or renders obvious holding the displayed size roughly constant, “regardless of the user movement.” Indeed, given Haan’s focus on helping the user see things more clearly with image magnification, Petitioner’s argument that it would have been obvious to hold the size of the image constant is not persuasive. See, e.g., Ex. 1005 ¶ 4.” slip op. at 23

    “Ex. 1005 ¶ 0111. Dr. Rubin testifies, succinctly, that “I do not believe that a [person of ordinary skill] would understand that Tajima uses the term ‘information regarding the key’ to refer to the key. If Tajima meant to say the ‘key,’ there would be no need to use the phrase ‘information regarding the key.’” Rubin II Decl. ¶ 41. He further testifies that “[w]hen Tajima wishes to refer to a ‘key,’ it does so directly” (citing many instances where Tajima makes explicit reference to keys). Id. ¶ 42 (citing Ex. 1005 ¶¶ 67, 70, 71, 75, 77, 86, 88, 89). We find Dr. Rubin’s reasoning on this issue persuasive. On the other hand, we find Dr. Bhattacharjee’s response less convincing.

Lacking support for disclosure of an encryption key in Tajima itself, Dr. Bhattacharjee turns to other references, including Foster. Id. ¶¶ 7–9. Dr. Bhattacharjee testifies that “Foster’s use of the term ‘key information’ to describe information that includes the key and additional information . . . explains why Tajima did not just say ‘key’ when referring to the information attached to the data fragments.” Id. ¶ 8. Dr. Bhattacharjee’s testimony is unconvincing. In Foster, there is explicit disclosure of including the encrypted title key itself in the header extension. Ex. 1006 ¶ 66 (“As depicted, header extension 118 includes encrypted title key 112 . . . “). In contrast, Dr. Bhattacharjee cites no similar disclosure in Tajima. In fact, Dr. Bhattacharjee’s reliance on other references to support anticipation runs contrary to the rule that “[a] claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros., Inc. v. Union Oil Co. of Cal., 814 F.2d 628, 631 (Fed. Cir. 1987) (emphasis added). We do not find Dr. Bhattacharjee’s testimony based on Foster and other references convincing of anticipation by Tajima. Nor do we find Petitioner’s alternative obviousness challenge based on Tajima persuasive. Pet. 22. The Petition includes a single-sentence explanation of this obviousness contention: “Even if Tajima had not disclosed that its key information includes the corresponding key, that would have been an obvious and conventional way to implement what Tajima discloses—i.e., a system that needs only the key information to decrypt data fragments and not additional key management infrastructure.” Id. (citing paragraph 104 of his initial declaration mirrors the Petition and provides no record citations to support his opinion of obviousness. Such unsupported expert testimony is entitled to little weight. “Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.” 37 C.F.R. § 42.65(a); PTAB Consolidated Trial Practice Guide 40 (Nov. 2019) (“Trial Practice Guide”) (“Opinions expressed without disclosing the underlying facts or data may be given little or no weight.”).6” slip op. at 17

As Petitioner points out, both Tajima and Foster are in the field of securing data, as is the ’116 patent. Pet. Reply 13–14 (citing Ex. 1005 ¶ 44; Ex. 1006 ¶ 3). Dr. Bhattacharjee testifies, “Tajima and Foster also both describe techniques for securing data using encryption and securely storing keys with encrypted data.” Bhattacharjee II Decl. ¶ 35 (citing Ex. 1005 ¶¶ 109–114; Ex. 1006 ¶¶ 64–71). Patent Owner argues Foster’s disclosure of a KEK would have been “redundant” to Tajima’s key-securing obfuscation technique. PO Resp. 18. We find this argument is unavailing. As Petitioner points out, Patent Owner’s argument “ignores Tajima’s vulnerability that Foster’s key-encryption addresses.” Pet. Reply 16. More specifically, “[r]equiring an attacker to obtain KEKs to decrypt Tajima’s encryption keys in addition to de-obfuscating them is not ‘redundant’ to only having to de-obfuscate them.” Pet. Reply 16 (emphasis omitted) (citing Bhattacharjee II Decl. ¶¶ 41–44). We find that Petitioner’s argument for combining the references is persuasive for the reasons given. Patent Owner further argues that Tajima and Foster address different problems and disclose solutions that are “fundamentally at odds.” PO Resp. 9–16, 25–27. Patent Owner asserts that “Foster’s system requires synchronizing the transmission of encrypted content packets with the keys used to encrypt those packets, so that each packet can be viewed immediately upon receipt.” Id. at 15 (emphasis omitted). Patent Owner attaching it to a different data fragment, the problem Foster sought to solve is the ‘need . . . for a key used to encrypt content to be itself encrypted, and transmitted as an integral part of the [same] content.’” Id. (alterations in original) (citing Ex. 1006 ¶ 7). We are not persuaded by this argument. As noted supra, for the reasons given, we find that both Tajima and Foster are in the field of securing data from unauthorized access. Pet. Reply 13. Furthermore, as Petitioner points out, we find that in Petitioner’s combination of Tajima and Foster, Tajima’s data (which does not require synchronization) is secured, not Foster’s. See Pet. 34–36 (providing reasons for encrypting Tajima’s keys); Pet. Reply 17–18 (“Synchronization of Foster’s data is irrelevant to Tajima-Foster because Tajima-Foster does not restore Foster’s data.”). Thus, we find that Patent Owner’s argument based on the need to synchronize Foster’s data for streaming is unavailing. We have considered Patent Owner’s other arguments and find them lacking. See, e.g., Patent Owner’s Sur-reply, which repeats the arguments that Tajima and Foster are in a “different field,” “fundamentally at odds,” “[i]n direct contrast,” and that applying Foster’s KEK teachings to Tajima would be “redundant.” PO Sur-reply 2–9.

Citing this testimony, Patent Owner argues, “Shyu’s anti-piracy system is a prototypical attempt to achieve security through obscurity, to the extent it proposes to conceal or obscure the encryption algorithms.” PO Resp. 33. Petitioner does not persuasively respond to this argument. Pet. Reply 20–21. Petitioner argues that “Shyu does not use secret algorithms.” Id. at 20. Instead, according to Petitioner “Shyu selects from among known algorithms to secure different data segments.” Id. However, we find Shyu’s disclosure that “the scrambling algorithm and the key word for the source data are dynamically changed to effectively guard against piracy” is telling evidence that the underlying algorithms themselves are not secure, and therefore Kerckhoff’s principle applies here. See Ex. 1016, 1:37–39. We also find persuasive reasoning in Patent Owner’s assertion that “[c]ombining associated with maintaining multiple encryption algorithms and tracking encryption algorithm ‘metadata,’ without providing any substantial security.” PO Resp. 34–35. In sum, for the reasons given, we agree with Patent Owner that Petitioner fails to prove sufficiently that a person of ordinary skill would have been motivated to combine Tajima and Rivest. Further, Petitioner fails to demonstrate that even assuming that Tajima and Rivest would have been combined, a person of ordinary skill would have further combined their teachings with Shyu.” slip op. at 25

Although we agree that the respective articulations are “somewhat different,” they are generally similar, and our Decision does not depend on nuanced distinctions regarding the level of ordinary skill. Indeed, Dr. Goodrich describes his proposed articulation as “approximate,” such that “more work experience could compensate for less education or more education could compensate for less work experience.” Ex. 2007 ¶ 50.

    “We agree with Patent Owner’s contention that the emphasized sentence defines the term “content-related.” See PO Resp. 15–16 (Patent Owner arguing that “[t]here are thus three strong indications of lexicography: (1) ‘content-related’ is set off by quotation marks; (2) the patentee used the word ‘is’ to describe the term ‘content-related’; and (3) the patentee states what ‘content-related’ is ‘understood to mean.’” Nor does Petitioner disagree that the sentence is definitional. See Tr. 8:15–16 (referring to the “term content-related as it’s defined in the specification”). Indeed, in the Starz litigation, the district court also treated the sentence as definitional, a fact that we find significant as a matter of comity. See Ex. 1018, 111:24–112:1 (district court judge stating at Markman hearing, “I’m going to adopt . . . the express definition provided in the specification”). But like the district court, we discern insufficient reason to adopt the additional gloss that Patent Owner seeks to apply to the definition of “content-related.” That is, Patent Owner proposes that we additionally construe the phrase “syntactical meaning” within the definitional statement to arrive at Patent Owner’s proposed construction. PO Resp. 16–20. According to Patent Owner, “[t]he specification makes clear, through its use of consistent and repeated examples, that ‘syntactical meaning’ requires a specific relationship between the data segments within a data file: succeeding data segments within a data file must be ordered so as to present the content in its intended sequence when rendered.” Id. at 17 (citing VirnetX Inc. v. Cisco Sys., Inc., 767 F.3d 1308, 1317–19 (Fed. Cir. 2014); Alloc, Inc. v. ITC, 342 F.3d 1361, 1368–71 (Fed. Cir. 2003)). Patent Owner adds that the claims, the context provided by the problems solved by the ’794 patent, and the cross-examination testimony of Petitioner’s expert, Dr. Freedman, all support this additional aspect of Patent Owner’s proposed construction. Id. at 18–20. Relying on additional direct testimony by Dr. Freedman, Petitioner counters this position as “improperly import[ing] limitations from the specification that are not required by the claims” and “render[ing] other portions of claim 1 superfluous.” Reply 3 (citing Ex. 1016 ¶ 22); see Tr. 10:18–20 (Petitioner explaining at oral hearing that “the syntax information is simply just identification information which is used to find out what the order of the files is. But the identification information does not by itself indicate the order. It’s just an identifier.”). We agree with Petitioner that it would be imprudent to adopt Patent Owner’s additional gloss because, “[w]hile claims must be construed in light of the specification, . . . limitations from the specification are not to be read into the claims, . . . for ‘[i]t is the claims that measure the invention.’” Golight, Inc. v.

It is apparent that the Applicant for the ’794 patent understood how to define terminology recited in the claims, but chose to limit its definition of “content-related” in terms of the broader phrase “syntactical meaning” rather than through narrower specific reference to presentation order. In addition, claims 1 and 9 already specify “sequentially outputting the first and second data segments according to their chronological sequence,” which supports Petitioner’s observation that requiring an additional sequential order to “content-related . . . data segments” renders other portions of claim 1 superfluous.

As such, a statement during prosecution qualifies as a disavowal of claim scope only if it is “so clear as to show reasonable clarity and deliberateness” and “so unmistakable as to be unambiguous evidence of disclaimer.” Id. at 1325 (citations omitted). “Consequently, for prosecution disclaimer to attach, [Federal Circuit] precedent requires that the alleged disavowing actions or statements made during prosecution be both clear and unmistakable.” Id. at 1325–26. “The party seeking to invoke prosecution history disclaimer bears the burden of proving the existence of a clear and unmistakable disclaimer that would have been evident to one skilled in the art.” Mass.

Patent Owner is correct that Rosenberg’s threshold is set at the time of the utterance in Rosenberg’s claim 5 and cites Petitioner’s declarant as “conceding” issues regarding how “Rosenberg’s volume threshold is determined.” PO Resp. 20–21. But this argument and the ostensible concession do not squarely address the proposed combination, which combines Fu’s teaching of an adjustment unit that “compares the volume of the ambient noise received . . . to a predetermined threshold” with Rosenberg’s teaching that such “a threshold may be ‘determined based on the volume of [an] ambient audio signal.’” Pet. 39, 40 (emphasis omitted) (quoting Ex. 1006, 14:28–30). While Patent Owner argues that “Petitioner has not proposed using a predetermined/pre-set threshold or a previously established threshold based on environmental noise in the combination of Hart-787 with F[u] and Rosenberg” (PO Resp. 46), we find, on the contrary, that the Petition describes a combination based predetermined threshold” and on a threshold “determined according to an environmental noise level.” Pet. 29–30. Thus, we find Petitioner’s unpatentability grounds do not suffer from the issues Patent Owner argues are a consequence of the purported use of the same sound data for the “first sound data” of claim limitation 1.a and for the “second sound data” of claim limitation 1.c. We do not agree with Patent Owner’s arguments regarding Fu’s teachings with respect to limitation 1.e’s “transition from a first state having a first volume level to a second state having a second volume level that is less than the first volume level” because these arguments similarly do not address the proposed combination. See PO Resp. 26–30. The Petition cites Hart-787 for attenuating the volume of an audio-producing device when a wake word is issued. Pet. 32–34, 43–44. The Petition cites Fu for adjusting volume of an audio-producing device if the level of ambient noise exceeds a predetermined threshold. Id. at 36–39, 44–45. Thus, even if Fu teaches only increasing the volume of an audio-producing device if the predetermined threshold is exceeded, the Petition relies on the combination of teachings of Hart-787 and Fu, and Patent Owner’s argument that neither reference teaches “decreasing a controllable appliance’s volume output when a previously established volume threshold is exceeded” (PO Resp. 30) does not address the combination proposed. Patent Owner’s argument that “Petitioner has not proposed modifying Fu to decrease a controllable appliance’s volume output when a volume threshold is exceeded” (PO Resp. 30) similarly does not address the combination proposed in the Petition. We also find that the preponderance of the evidence supports Petitioner’s showing regarding the motivation to combine the references.” slip op. at 23

A reference is considered “publicly accessible” if it was “disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art, exercising reasonable diligence, can locate it.” Id. at 1355–56 (citing In re Wyer, 655 F.2d 221, 226 (CCPA 1981)). Petitioner treats this requirement as having two aspects, namely (1) whether a person of ordinary skill could reasonably have found RemoteCentral.com and (2) whether such a skilled artisan could reasonably have found RadioShack on RemoteCentral.com. Reply 8–13; see also Tr. 33:25–34:8 (Patent Owner asserting that there are two aspects to the analysis on public accessibility: “The first is whether a [person of ordinary skill in the art] would have known to arrive at the website containing the prior art reference.

Specifically, after a petitioner has presented “evidence sufficient to establish a reasonable likelihood that the reference was publicly accessible before the critical date of the challenged patent,” such that trial is instituted, “some limited opportunities exist for the petitioner to present new evidence later.” Hulu at 13–14. These “limited opportunities” include “in a reply to the patent owner response,” provided that the additional evidence is “responsive to the prior briefing” and provided that the additional evidence does not require “completely reopen[ing] the record, by, for example, changing theories after filing a petition.” Id. at 14–15.

Rather, the 7 Patent Owner appears to refer incorrectly to Exhibit 1040 instead of Exhibit 1041 when identifying “articles allegedly referring to RemoteCentral.com.” See Sur-reply 5–6. progression within the instant proceeding comports well with the Hulu framework. During the preliminary proceeding, Petitioner came forth with “evidence sufficient to establish a reasonable likelihood that [RadioShack] was publicly accessible before the critical date of the challenged patent,” just as Hulu demands. Hulu at 13; Inst. Dec. 23 (“[W]e determine that Petitioner’s showing regarding public accessibility of RadioShack is sufficient under the standard we apply at this stage of the proceeding.”). Patent Owner challenges RadioShack’s status as a printed publication in its Response, just as Hulu contemplates. Hulu at 15; PO Resp. 28–41. And Petitioner submits additional evidence that replies to that challenge without changing its theory that RadioShack qualifies as a printed publication by virtue of its accessibility on the RemoteCentral.com web site and in light of date indicia on RadioShack itself.8 See Hulu at 15–16; Reply 7–13. Moreover, in determining that Petitioner’s additional evidence directed at RemoteCentral.com is properly considered, we are further mindful of the Federal Circuit’s endorsement that “the petitioner in an inter partes review proceeding may introduce new evidence after the petition stage if the evidence is a legitimate reply to evidence introduced by the patent owner.” Anacor Pharm., Inc. v. Iancu, 889 F.3d 1372, 1830–81 (Fed. 8 In its Reply, Petitioner also relies on evidence of publication of RadioShack on Radio Shack’s own public website and on “a third location,” hifi-remote.com.

    “Patent Owner asserts that in Petitioner’s analysis of claim 16, “Petitioner reads out any distinctions between ‘at least a subset’ and ‘a subset.’” PO Resp. 45. Petitioner responds that “[t]he Board should reject Patent Owner’s argument that ‘the subset’ must be a ‘proper subset,’ i.e., a set that is less than the full set of outgoing data.” Pet. Reply 5. Petitioner cites dictionary definitions and other additional authorities to support this conclusion. Pet. Reply 5–6 (citing, e.g., Exs. 1022, 1023, 1024). For example, A Dictionary of Computing defines “subset” as “[a] set T whose members are all members of S,” and contrasts this with a “proper subset.” Ex. 1023, 3. Petitioner further points out that the antecedent basis of “at least a subset” for “the subset” in claim 16 supports its construction. Pet. Reply 6. In our Final Written Decision, after considering Petitioner’s evidence and the language of the claim, we found that the references to “subset” in claim 16 should be construed broadly enough to read on providing any portion of the outgoing data, up to and including all the data, and not a proper subset. FWD 24–25.

We agree with Petitioner that Patent Owner’s argument is not convincing.

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.

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Petitioner’s proposed level of ordinary skill does not differ materially from that presented by Mr. Welch. Both require a bachelor’s degree in many of the same fields and roughly one to two years of experience with USB protocols or USB product development. The arguments presented by Petitioner and Patent Owner do not indicate that the outcome of this case would change depending on the level of ordinary skill in the art. We, therefore, adopt Petitioner’s description, which we determine to be consistent with the level of skill reflected in the asserted prior art references. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). We note, however, that we would reach the same conclusions under either proposed level of ordinary skill.” slip op. at 8

  • BurdenDecided for patent owner

    “Proof of conception must be by “corroborating evidence which shows that the inventor disclosed to others his ‘completed thought expressed in such clear terms as to enable those skilled in the art’ to make the invention.” Coleman v. Dines, 754 F.2d 353, 359 (Fed. Cir. 1985) (citing Field v. Knowles, 183 F.2d 593, 601 (CCPA 1950)); see also Mahurkar v. C.R. Bard, Inc., 79 F.3d 1572, 1577 (Fed. Cir. 1996) (corroboration requirement “arose out of a concern that inventors testifying in patent infringement cases would be tempted to remember facts favorable to their case by the lure of protecting their patent or defeating another’s patent”). Similarly, an inventor’s testimony alone is insufficient to establish an earlier reduction to practice. Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1169–71 (Fed. Cir. 2006). Instead, a party seeking to prove an actual reduction to practice must proffer evidence corroborating that testimony. Id. at 1170. The sufficiency of corroboration is determined according to a “rule of reason.” Price v. Symsek, 988 F.2d 1187, 1195 (Fed. Cir. 1993). This, however, does not dispense with the requirement that some independent evidence provide corroboration. Coleman, 754 F.2d at 360. The requirement of “independent” corroboration requires evidence other than the inventor’s testimony. In re NTP, Inc., 654 F.3d 1279, 1291–92 (Fed. Cir. 2011). 3. Discussion We find that Patent Owner has not met its burden of establishing that Mr. Kuster conceived and reduced to practice his invention prior to the filing dates of Hsiao or He. By itself, Mr. Kuster’s testimony is insufficient to establish that he reduced his invention to practice prior to the November 23, 2010, filing date or Hsiao or the June 2, 2010, filing date of He. “Throughout the history of the determination of patent rights, oral testimony by an alleged inventor asserting priority over a patentee’s rights is regarded with skepticism, and as a result, such inventor testimony must be supported by some type of corroborating evidence.” Woodland Tr. v. Flowertree Nursery, Inc., 148 F.3d 1368, 1371 (Fed. Cir. 1998) (quoting Price, 988 F.2d at 1194). Patent Owner has failed to provide sufficient independent evidence corroborating Mr. Kuster’s testimony.” slip op. at 20

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

    “We do not agree with this argument. “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” MCM Portfolio LLC v. Hewlett-Packard Co., 812 F.3d 1284, 1294 (Fed. Cir. 2015) (quoting In re Keller, 642 F.2d 413, 425 (CCPA 1981)). Moreover, “[a] person of ordinary skill is also a person of ordinary creativity, not an automaton,” so the fact that it would take some creativity to carry out the combination does not defeat a finding of obviousness. KSR, 550 U.S. at 421; see also ClassCo, Inc. v. Apple, Inc., 838 F.3d 1214, 1219 (Fed. Cir. 2016) (“The rationale of KSR does not support [the] theory that a person of ordinary skill can only perform combinations of a puzzle element A with a perfectly fitting puzzle element B.”). We find there is support for making this combination of He and Cheng in the testimony of Dr. Baker that addition of a controller is “conventional” in USB flash drives. Baker Decl. ¶ 167. We find that for the reasons given by Dr. Baker, a person of ordinary skill would have added a controller to He. We determine that the combination of He and Cheng teaches each limitation of claim 11. We address Patent Owner’s argument that there are objective indicia of obviousness, infra. We conclude that Petitioner has demonstrated that claim 11 would have been obvious over He and Cheng.” slip op. at 37

  • Obviousness (§103) › Objective indicia / secondary considerations › Long-felt need / failure of othersDecided for patent owner

    “attorney argument, not evidence.” Pet. Reply 26. We agree. Patent Owner does not back up its argument with testimony or other credible evidence. To demonstrate long-felt need, a patentee must point to an “articulated identified problem and evidence of efforts to solve that problem” which were, before the invention, unsuccessful. Tex. Instruments v. Int’l Trade Comm’n, 988 F.2d 1165, 1178 (Fed. Cir. 1993). All Patent Owner proves, if anything, is that after the USB 3.0 specification issued, a number of companies rushed in to provide contacts that met the new standard. Patent Owner does not demonstrate that they failed where Mr. Kuster succeeded. In fact, there is no evidence that Mr. Kuster ever commercialized his invention.8 8 Victorinox never paid for the work Mr. Kuster did on the USB 3.0 memory device, and to Mr. Kuster’s knowledge, never marketed the product. Kuster Dep. 22:21–24:13. Patent Owner contends “Mr. Kuster’s invention filled the existing need for a durable yet slim USB flash drive compatible with USB 3.0 that was easy to manufacture.” PO Resp. 77. But instead of presenting independent evidence of failure of the others to solve known technical or manufacturing problems, Patent Owner relies on generalized statements concerning the need for USB 3.0 connectors and solutions by others that Patent Owner contends have not been successful. PO Resp. 74–77. We are not persuaded by Patent Owner’s argument that Mr. Kuster’s alleged invention filled a long-felt need where others failed.” slip op. at 29

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

    “The principal difficulty with Patent Owner’s arguments is that they improperly conflate transferring desktop information with the claim’s 4 The ’288 patent instead uses the uncommon acronym “PAUNTSC,” presumably a result of incorrectly printing “L/” as “U.” recitation of “capturing” desktop information. Indeed, Dr. Bhattacharjee concedes that “the desktop information as described in the ’288 patent is transferred in digital form,” even as he maintains his opinion that desktop information is not limited to digital capture by the ’288 patent. Ex. 1020 ¶ 11. There is thus no dispute among the expert witnesses, nor the parties, that the ’288 patent describes the digital transfer of desktop information. As Dr. Bhattacharjee explains, this is a consequence of the fact that “the [’288] patent describes and claims transferring desktop information only after it is encoded.” Ex. 1020 ¶ 12. Because such encoding occurs only after the desktop information is captured, “the captured desktop information could either be digital or analog.” Id. The aspects of the intrinsic record that Patent Owner identifies as supporting its proposed construction are, in fact, consistent with this distinction between capture and transfer. For example, the “advantage of the invention” identified by Patent Owner is specifically described by the ’288 patent as raising clarity on the video communication terminal when “[d]esktop information of a PC is transferred directly in a digital coded bit stream mode without converting digital signal to analog signal.” See Ex. 1001, 2:35–39 (emphasis added). This is, moreover, consistent with the portion of the prosecution history Patent Owner identifies and which also makes clear that “the desktop information of a PC is transferred in a digital coded bit stream.” Ex. 1002, 159 (emphasis added). Petitioner’s expert, Dr. Bhattacharjee “agree[s] the desktop information as described in the ’288 patent is transferred in digital form,” even though it is not captured in digital form. Ex. 1020 ¶ 11. And although the ’288 patent’s remarks about the “second” prior-art” slip op. at 14

    “Both proposals appear reasonable on the record before us. Although we invited the parties “to address whether material differences exist between their respective proposals and what impact, if any, the different proposed levels have on the obviousness analysis,” neither party has done so. See Dec. 11 n.3. We apply the proposal articulated by Patent Owner, but we would reach the same conclusions under either proposal.” slip op. at 12

  • Expert testimonyPetitioner expert creditedDecided for petitioner

    “skill in the art] would be motivated to combine even when bandwidth is shared”: (1) “the shared nature of the bandwidth only highlights that reduced bandwidth usage for desktop information provides the capability of a higher quality signal for the live stream without any extra costs in components or processing”; (2) because Kenoyer ’423 “does not disclose using a dedicated or fixed amount of bandwidth . . . , any reduction in bandwidth would reduce overall usage”; and (3) “even in a dedicated environment, Kenoyer ’423’s reduced bandwidth needs for desktop information would reduce the amount of dedicated bandwidth that is required, potentially saving costs or power.” Reply 12 (citing Ex. 1020 ¶¶ 31–32). These reasons are directly responsive to arguments raised by Patent Owner in its Response and are therefore properly considered. See 37 C.F.R. § 42.23(b). We also find such reasons, which are supported by additional testimony by Dr. Bhattacharjee, adequately explain how Patent Owner’s distinction is accommodated within Petitioner’s expressed rationale of “minimizing bandwidth usage.” See Ex. 1020 ¶¶ 31–32. Second, Patent Owner contends that, if “Kenoyer ’423 were interpreted as teaching reducing bandwidth, it does so in a different manner than in Becker.” PO Resp. 37. Specifically, “Becker addresses bandwidth reduction by using signal compression techniques,” Patent Owner says, while “Kenoyer ’423 prevents the increase in bandwidth . . . by dynamically sharing bandwidth when both a live view of the presenter and the presenter’s computer screen are being shared.” Id. Dr. Bhattacharjee disputes this distinction by observing that Kenoyer ’423’s technique still “reduces the number of bits required to convey the same video information,” and is thereby broadly encompassed as a form of “signal compression.” Ex. 1020 ¶ 33. Dr. Rosing does not specifically disagree with Dr. Bhattacharjee’s characterization. See generally Ex. 2022 ¶ 99. Regardless, both Becker and Kenoyer ’423 support Petitioner’s rationale of “minimizing bandwidth usage.” Patent Owner inadequately explains how a distinction in the precise manner that might be accomplished by the two references diminishes the support provided by the rational underpinnings identified by Petitioner. See PO Resp. 37 (Patent Owner making the conclusory statement that “[a]s such, Petitioner fails to provide a valid motivation for combining Becker and Kenoyer ’423”).” slip op. at 26
