    “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). Patent Owner does not, however, identify any way that those claim constructions affect our analysis of the parties’ patentability disputes.

    “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

    “Patent Owner’s expert, Dr. Goodrich, proposes what Patent Owner characterizes as “a somewhat different level,” namely “an individual with at least a bachelor’s degree in Computer Science or related area and two years of experience developing software tools and/or computer systems for use in the area of audio or video creation, encoding, and/or distribution.” PO Resp. 13; Ex. 2007 ¶ 50. 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. Because we find Petitioner’s proposal reasonable, consistent with the level of skill reflected by the prior art, and supported by Dr. Freedman’s testimony, we adopt it for this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art). We nevertheless note that we would reach the same ultimate conclusion that claims 1, 3, 5, 9, 12, 13, and 15 (but not claims 20 and 21) have been shown to be unpatentable by a preponderance of the evidence were we to adopt Patent Owner’s proposal.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for patent owner

    “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. Wal-Mart Stores, Inc., 355 F.3d 1327 (Fed. Cir. 2004) (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 (Fed. Cir. 1985) (other citations omitted). 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.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalDisclaimer not foundDecided for petitioner

    “As a basic principle of claim interpretation, prosecution disclaimer promotes the public notice function of the intrinsic evidence and protects the public’s reliance on definitive statements made during prosecution.” Omega Engineering, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed Cir. 2003) (citing Digital Biometrics, Inc. v. Identix, Inc., 149 F.3d 1335, 1347 (Fed. Cir. 1998)) (emphasis added). 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. Inst. of Tech. v. Shire Pharms., Inc., 839 F.3d 1111, 1119 (Fed. Cir. 2016). And “[s]tatements by the patent owner are not considered in a vacuum; rather, the skilled artisan would look at the record as a whole in assessing claim scope.” Galderma Lab’s v. Amneal Pharma, 806 F. App’x 1007, 1010 (Fed. Cir. 2022) (citing Wang Labs., Inc. v. Toshiba Corp., 993 F.2d 858, 867 (Fed.

We have reviewed the prosecution history, which we summarize supra § I.A.3., and we have particularly reviewed those portions highlighted by Patent Owner. See PO Resp. 32–40. We reach the same conclusion as the district court in the Starz litigation that the standard for attachment of prosecution disclaimer is not met. See Ex. 1018, 109:15–22 (district court stating at Markman hearing, “I’ve also carefully reviewed the portions of the prosecution history relied on by VideoLabs, including the patentee’s arguments regarding the Shin and Rosenau references, and I’m up [sic: not6] persuaded there was a clear and unmistakable disclaimer of all assignment rules that perform assignments by using exact timing information”). slip op. at 20

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.

    “addressed squarely by the principles set forth in Hulu, which addresses the standards at the institution stage and during the trial for evaluating evidence proffered to show asserted art qualifies as a printed publication. 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. Although Patent Owner contends that “[t]his is not an example of permissible rebuttal evidence, but rather a belated attempt to fill a gap in the evidence in the Petition,” we disagree. See Sur-reply 6. 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. Reply 14. As we discuss below, we determine that the presence of RadioShack on RemoteCentral.com is sufficient to qualify RadioShack as a printed publication. We therefore do not reach the issue of whether presence on either the Radio Shack web site or on hifi-remote.com is an improper new theory raised by Petitioner in its Reply. See Tr. 8:13– 9:23 (Petitioner discussing whether reliance on hifi-remote.com presents a different theory than set forth in the Petition). Cir. 2018); see also Vidstream LLC v.

    “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.

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.

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.

    “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.

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.

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.

    “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.

  • RemandOther

    “After this proceeding was remanded by the Federal Circuit, we invited the parties to address a proposed procedure that would include additional briefing regarding the impact of the prior holdings that claims 1–3, 5, and 10–20 are unpatentable, and the parties filed their respective proposals. Papers 78–80. In its proposal, Petitioner suggested that Patent Owner “has waived the right to address the patentability of claims 4, 8, and 9” because “Patent Owner never separately argued for the patentability of these claims.” Paper 79, 1; see MaxLinear, 880 F.3d at 1378 n.4 (“On remand, the Board may consider whether CRESPE has waived arguments concerning these claims.”). But those claims were not challenged in the earlier proceedings that held claims 1–3, 5, and 10–20 unpatentable. Rather, those claims were only challenged in this proceeding with respect to art that was not at issue in the earlier proceedings. In advancing its contention, Petitioner effectively makes the untenable argument that Patent Owner must provide separate reasons for the patentability of claims 4, 8, and 9, even when we determine that its own case-in-chief for those claims is insufficient. In addition, Petitioner’s proposal requests briefing on the issues of “whether claims 6, 7 and 20 materially alter the [unpatentability] analysis on which the prior [unpatentability] determinations rested.” Id. We have considered, and deny, that request. The Federal Circuit’s remand order noted that the fact that “MaxLinear was not a party to the other IPRs is . . . irrelevant since Cresta, the predecessor in interest to CRESPE, was party to the original determination.” MaxLinear, 880 F.3d at 1377. But the Federal Circuit’s order does not state or suggest that the fact that different prior art was considered in the earlier proceedings is similarly irrelevant. Indeed, we agree with Patent Owner that “[t]he Federal Circuit has not ordered the Board and the parties to start over from scratch, and certainly not with new prior art.” Paper 80, 3; see Ariosa Diagnostics v. Verinata Health, Inc., 805 F.3d 1359, 1367 (Fed. Cir. 2015) (“The Board may control its own proceedings, consistent with its governing statutes, regulations, and practice.”). Patent Owner is correct that “[a]llowing new prior art to be considered on remand after the Final Decision on the merits would essentially be starting a new IPR proceeding.” Paper 80, 9. As Patent Owner asserts, “[t]he parties and the Board would have to argue and consider new grounds, new expert testimony would have to be taken and presented, and a new Final Decision would have to be rendered.” Id. The Federal Circuit’s instruction is limited: “We remand this case to the Board so that it may consider the patentability of the surviving disputed dependent claims 4, 6-9, and 21.” MaxLinear, 880 F.3d at 1378. We have complied with this instruction in two ways: first, by applying the Federal Circuit’s instruction regarding the collateral-estoppel impact on challenged claims 1–3, 5, and 10–20; and, second, by clarifying that Petitioner’s argument regarding the combination of Van De Plassche and Ishikawa compels a conclusion that Petitioner’s showing is insufficient with respect to claims 4, 6–9, and 21, independent of any conclusion previously reached with respect to independent claims 1 and 17. While the Federal Circuit includes language in its remand order that might be construed as suggesting applying different prior art in the latter analysis, 880 F.3d at 1377, the scope of this proceeding is limited by the prior art and the arguments in the Petition here.

Ct. at 1356 (“in an inter partes review the petitioner is master of its complaint”); see Paper 80, 8 (Patent Owner addressing potential ambiguity of Federal Circuit’s instruction).” slip op. at 35

    “Experience is but one of several factors that may be considered when determining the level of ordinary skill in the art. See, e.g., In re GPAC, 57 F.3d 1573, 1579 (Fed. Cir. 1995) (identifying factors as 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 a given case, every factor may not be present, and one or more factors may predominate.” Id. Patent Owner’s distinction relates to a portion of one factor (education) in a determination that involves several factors. The significance of the level of ordinary skill in the art is the role it plays in an obviousness analysis. See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966); Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Patent Owner does not explain persuasively how the alleged omission by Petitioner impacts the obviousness analysis.

    “Importantly, we find that Patent Owner did not exhaust avenues available to it in attempting to secure answers to its questions from Dr. Hashemi. The line of questioning involving Exhibit 2008 occurred late in the day, “well after the close of business on the east coast,” and an attempt by the parties to telephone the Board during the deposition was unsuccessful. See Opp. 3; Ex. 2006, 154:24–155:4. The parties discussed contacting the Board the following day, and continuing the deposition the day after that, when Petitioner would make Dr. Hashemi available for further cross-examination after receiving guidance from the Board. Ex. 2006, 155:5–157:13. Rather than proceed in this fashion, Patent Owner decided to abandon the line of questioning and passed the witness for redirect: “I think after we talked about it a bit, I think we will withdraw our questions on this document and just move on to redirect.” Id. at 157: 22–25 (emphasis added). Dr. Hashemi could have answered the questions and sought a protective order that would insulate his answers from the public record, providing the Board with the information needed to perform a focused evaluation of the credibility and reliability of specific statements in his testimony. But a significant measure of responsibility for whether Dr. Hashemi’s testimony is tainted with bias lies with Patent Owner for declining to pursue the issue to a point of greater clarification. Indeed, we are limited in how strongly we can fault Petitioner for failing to submit a clarifying declaration from Dr. Hashemi, in light of Patent Owner’s decision to “withdraw” the questions at issue. Because the evidence is insufficiently developed, we are similarly limited in the degree to which we can draw adverse inferences from Dr. Hashemi’s refusal to answer questions, and unable to conclude, by a preponderance of the evidence, that Dr. Hashemi’s testimony is tainted by an undisclosed bias.

    “We find the ’212 Patent is directed to data for a particular user (see, e.g., ’212 Patent, Abstract). This conclusion is supported by the Specification. Indeed, all discussion in the ’212 patent is directed to a pedometer for use by and relying on data obtained from an individual user. Thus, the Specification suggests that the term “calibration” should be construed as a process that correlates a user’s stride rate and stride length. The Oral hearing confirms this conclusion. In the Oral Hearing, Petitioner’s counsel, Mr. Doshi, responded to a request to identify the calibration and the plurality of calibrations as follows: JUDGE STEPHENS: So what are you pointing at in the 212 patent as being [a] calibration and the plurality of calibrations? MR. DOSHI: That’s in column 5. So at column 5 it says that after a proper warm up the user completes a sample run or walk on the track at normal pace, et cetera, et cetera. So it's saying that here’s S1 and following completion of the first run, so here it’s saying you’re doing different walks at different speeds . . .where you're having the user walk at different walking speeds and measuring their step size as you do that (Trans. 21:1–10; see also Tr. 19:4–7) JUDGE ZADO: Okay. And then so taking that further then, I understand your argument to be that in the 212 patent the runner for the first sample S1 will run at one pace and that’s, according to Petitioner, that's one calibration and then the runner will run at a second pace for the S2 sample and that’s the second calibration, and then the runner will run at a third pace and then that's the S3 sample and then that's a third calibration? Is that Petitioner's argument? MR. DOSHI: Yes 13 (Tr. 22:4–11). Therefore, based on Petitioner’s statements at the Oral Hearing, the term “calibration” should be construed as the process of taking a sample that correlates step rate and step length for an individual.” slip op. at 13

The technology of the ‘212 Patent implicates other fields, such as Sports Medicine, Exercise Science, and Physiology. I believe that a bachelor’s degree in one of these fields, or a similar field, with at least two years of practical experience working with pedometers and/or health or fitness trackers or sensors, or an advanced degree in one of these areas, could qualify one as a PHOSITA in this case (Ex. 2001 ¶ 26).

    “Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved (In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004)). Here, Petitioner has persuaded us that Levi is from the same field of endeavor as the ’212 Patent –– pedometers that count the number of steps taken to calculate distance traveled (see Pet. 20). Specifically, although Levi adds a navigation feature, Levi is directed to a pedometer that, in pertinent part, adjusts step size according to step frequency in order to estimate distance traveled by a user (Levi, 6:6–43). Levi states “[t]he present invention for a ground speed/distance sensor is an improvement over a common hiker’s pedometer” and “[t]he present invention analyzes the frequency of a user’s footsteps to aid in the detection of future footsteps, and further to aid in determining the size of footsteps taken by the user” (Levi, Abstract, 2:57–60, 2:65–67). Similarly, the ’212 Patent is directed to a pedometer and specifically, a pedometer that calculates actual stride lengths of a user based on relative stride rates (’212 Patent, Abstract). Thus, both the ’212 Patent and Levi are from the same field of endeavor –– pedometers or devices that include or rely on pedometers.

We further credit Mr. Blackadar’s testimony that an ordinarily skilled artisan would have been motivated to improve Jimenez using Levi’s dynamic step size algorithm, to improve the calculated distances (Ex. 1005 ¶¶ 92). Indeed, we find that an ordinarily skilled artisan would have been motivated to combine the teachings of Jimenez and Levi to “monitor [ ] the distance traveled more accurately than prior pedometers that calculated distance based on average stride length” (Pet. 31 (citing Ex. 1005 ¶ 90), 32 (citing Ex. 1005 ¶ 92)). In particular, we find that, given it was known a user’s stride length could vary with stride rate, as admitted by Patent Owner (PO Resp. 52), an ordinarily skilled artisan would have been motivated to implement a data processor that accounted for this relationship, such as that described in Levi (Pet. 32–33 (citing Ex. 1005 ¶¶ 93–94)).” slip op. at 49

    “Mr. Mombers, a Group B inventor, testified to the ITC that he conceived of the signal processor of claim 1, the sole independent claim of the ’792 patent, and thus conceived of every claim of the ’792 patent. All of the evidence presented to the ITC that was submitted and argued here is consistent with Mr. Mombers’s assertion. Patent Owner corroborated this testimony by stating that Favrat is prior art under § 102(e), meaning it is “by another.” Considering the entire admissible record, we determine that a 19 In re Land, 368 F.2d 866 (Fed. Cir. 1966), is also distinguishable because the patents were related. preponderance of the evidence demonstrates that Favrat is “by another” as required by § 102(e).” slip op. at 23

    “Consequently, with regard to claims 3, 6–10, and 12–17, Patent Owner has failed to carry its burden of establishing when the ’792 patent “was made.” As a result, the safe haven of § 103(c) does not apply, and we need not reach the question of common ownership or obligation of assignment as of the filing date of the ’792 patent. b) Claims 18–23 The evidence provided by Petitioner does not address claims 18–23. See Ex. 1212, 5–6. That is, Patent Owner did not assert these claims were conceived and reduced to practice at an earlier date. Given the absence of evidence to the contrary, the presumption that the ’792 patent “was made” as of its filing date applies. Our inquiry is then whether as of that date, Favrat and the ’792 patent were “owned by the same person or subject to an obligation of assignment to the same person.” See 35 U.S.C. § 103(c)(1). As explained above, Patent Owner asserts, with supporting evidence, that Favrat and the ’792 patent were commonly owned as of the filing date of the ’792 patent. Petitioner provides no evidence to the contrary regarding 23 Petitioner contends, without supporting evidence, that because the references asserted against Patent Owner in the ITC proceeding predated even the May 2001 date, Patent Owner changed to rely upon the filing date of the ’792 patent as the priority date.

Rather, Petitioner provides argument and evidence regarding common ownership and obligation of assignment for dates prior to the filing date of the ’792 patent. See Pet. Reply 17–24. We need not consider this argument and evidence as it does not pertain to the date at issue (i.e., the filing date of the ’792 patent, which is the date that claims 18–23 were made). In light of this, Patent Owner has demonstrated that claims 18–23 are subject to the safe haven of § 103(c). Consequently a ground of unpatentability based on obviousness may not be asserted against Patent Owner for these claims.” slip op. at 27

    “because it is in response to Patent Owner’s argument in the Response that Favrat is not prior art under § 102(a). See PO Resp. 22 n.2; Paper 71, 1. However, this does not end our inquiry. If the assertion that Favrat is prior art under § 102(a) was required to be in the Petition, then the fact that the issue was raised in Patent Owner’s Response does not cure that oversight. As the Federal Circuit recently emphasized, It is of the utmost importance that petitioners in the IPR proceedings adhere to the requirement that the initial petition identify “with particularity” the “evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3). Intelligent Bio-Systems, 821 F.3d 1359, 1367–68 (Fed. Cir. 2016); see also 37 C.F.R. § 42.104(b)(2) (requiring a petition to specify the specific statutory grounds under 35 U.S.C. § 102). Prior to filing of the instant Petition, Petitioner knew from Patent Owner’s contentions in the ITC proceeding that the safe haven of § 103(c) was a potential issue. See Ex. 1207, 3. Even armed with this knowledge, Petitioner chose not to assert in the Petition that Favrat is prior art under § 102(a). If Petitioner had asserted both § 102(a) and § 102(e), perhaps Patent Owner would have chosen a different response and the evidence in this proceeding would have developed differently. In the particular circumstances of this case, adding consideration of § 102(a) at this late date would deprive Patent Owner of due process. Consequently, we do not consider Petitioner’s contention that Favrat is prior art under § 102(a).” slip op. at 29

    “the ‘first sensing circuit’ and the ‘second sensing circuit’ sense power simultaneously,” and further argues “[n]or does Patent Owner present any argument with reference to, e.g., the 459 Patent specification or prosecution history as to why this additional limitation should be read into this claim.” Pet. Reply 23. Petitioner’s reply, however, fails to recognize that Petitioner bears the burden of demonstrating that Mullin anticipates the claim, including providing sufficient evidence and argument in support of its proposed claim interpretation. The Petition fails to provide a sufficient explanation to support that “when both” should be construed in the manner asserted by Petitioner, particularly when the more natural reading of the claim language conveys that two sensing circuits sense power at the same time. Although Petitioner provided a second declaration from Mr. McAlexander in reply to Patent Owner’s response, neither that declaration nor Mr. McAlexander’s first declaration provides sufficient support for how claim 2 would have been understood by a person of ordinary skill to show that it is anticipated by Mullin. See Exs. 1007 and 1011. Because Petitioner failed to persuasively prove that claim 2 requires only that one of two sensors senses power for the motor controller to determine that power is applied to the second input, Petitioner has not shown by a preponderance of the evidence that claim 2 of the ’459 patent is anticipated by Mullin.” slip op. at 14

    “Mot. 15. Patent Owner’s attorney argument, which cites no evidence, does not support the contention that the proposed amended claim would not have been obvious to a person of ordinary skill in the art. Nonobviousness cannot be established by attacking the references individually when unpatentability is predicated upon a combination of prior art disclosures. See In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986). Even if each prior art reference is “missing at least two of the required limitations,” that has limited bearing on whether a combination of those references renders the claim obvious. Similarly, Patent Owner provides insufficient support for its implicit argument that one would not combine the references because, individually, they provide a “complete solution” to the problem they intend to address. Where “a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 416 (2007). Thus, Patent Owner’s suggestion that there “is no reason one of skill would engage in mixing and matching,” fails to adequately address whether the combination would have been obvious. See Mot. 15.” slip op. at 28

    “We agree with Petitioner that, for Mullin to anticipate claim 1, Mullin need not disclose power sensed at COM. See Pet. Reply 19–22. The claim language does not require power to be sensed at any specific location, only that one sensing circuit senses “power applied to” the first and second inputs, and the other senses “power applied to” the second and third inputs. Patent Owner does not direct us to any persuasive disclosure in the ’459 patent to support its contention that claim 1 requires that power be sensed at the second input. See PO Resp. 21–26. Similarly, although Dr. Horenstein states that “the Mullin circuit is incapable of providing unique information that power has been connected to COM,” a point not in dispute, Dr. Horenstein provides only conclusory assertions and no persuasive explanation for why claim 1 would be understood to require such “unique information” for the second input. See Ex. 2001 ¶¶ 56, 63. Moreover, in Mullin, when a sensor detects power at either P2 or P3, power is necessarily applied to COM (neutral) to complete the circuit, even if the sensor does not directly detect power at COM. As Dr. Horenstein explained, “at least two inputs from the source of AC power – generally line and neutral – would have to be connected in order to complete the circuit and enable the flow of power to the motor.” Ex. 2001 ¶ 53. Mr. McAlexander similarly explained that by the very nature of alternating current, “the flow of electric charge periodically reverses direction.” Ex. 1011 ¶ 12. Thus, when alternating current is applied to Mullin’s input P2 and COM it will “be input from the input P2 and return by way of the COM, and at other times it will be input from the COM and return by way of the input P2.” Id. ¶ 13. The same is true of P3 and COM. See id. As shown by Petitioner, Dr. Horenstein confirmed during cross-examination that, when AC power, as referred to in Mullin, is applied to the power input P2 and common input COM as shown above, the opto-isolator ISO1 senses this power and outputs a corresponding signal, [and] when Mullin’s AC power is applied to the power input P3 and common input COM as shown above, the opto-isolator ISO2 senses this power and outputs a corresponding signal. Pet. Reply 22; see also Ex. 1010, 68:24–69:19. Accordingly, the testimony of Mr. McAlexander and Dr. Horenstein supports our determination that Mullin discloses a first sensing circuits that “senses power applied to the first and second inputs” and a second sensing circuit that “senses power applied to the second and third inputs,” as well as a motor controller that is “operable for determining that power is applied to the first input when the first sensing circuit senses power,” as required by claim 1.” slip op. at 11

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

    “Ex. 2001 ¶¶ 104–105. Thus, Dr. Horenstein contends there is a lack of a motivation to combine the references because opto-couplers are simpler and require fewer parts than the current based sensor of Nordby. In KSR, the Supreme Court rejected the Federal Circuit’s rigid application of its “teaching, suggestion, motivation” test in favor of an expansive and flexible approach. 550 U.S. at 415. The Supreme Court noted that often, it will be necessary: to look to interrelated teachings of multiple patents; the effects of demands known to the design community or present in the marketplace; and the background knowledge possessed by a person having ordinary skill in the art, all in order to determine whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue. Id. at 418. Moreover, the Federal Circuit has explained that: an implicit motivation to combine exists not only when a suggestion may be gleaned from the prior art as a whole, but when the “improvement” is technology-independent and the combination of references results in a product or process that is more desirable for example because it is stronger, cheaper, cleaner, faster, lighter, smaller, more durable, or more efficient. Because the desire to enhance commercial opportunities by improving a product or process is universal – and even common-sensical – we have held that there exists in these situations a motivation to combine prior art references even absent any hint of suggestion in the references themselves. In such situations, the proper question is whether the ordinary artisan possesses knowledge and skills rendering him capable of combining the prior art references. Dystar Textilfarben GmbH & Co. Deutschland KG v. C.H. Patrick Co., 464 F.3d 1356, 1368 (Fed. Cir. 2006). In this case, Patent Owner’s contention that there is no motivation to substitute one sensor for another is not supported by anything beyond conclusory statements. Moreover, contrary to the assertion that voltage and current sensors are “not substitutable,” Nordby expressly states that “[v]oltage (potential) sensing may be used, or alternately, current (flow) sensing may be used. Since the sensing scheme is used only to detect the presence or absence of voltage or current on the sensed line and does not require any significant accuracy, the cost of either type of sense circuitry can be made very low.” Ex. 1004, 4:43–48. In light of the evidence that current and voltage sensors were known to be interchangeable, Patent Owner’s contention that there was “no reason one of skill would have sought to replace those voltage based opto-isolator systems with the bulky current transformer and attendant circuitry of Nordby,” is insufficient to demonstrate the combination of references was not obvious.
