“On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms. See e.g., Ex. 1001, 10:17–11:14, 12:65–13:8, 14:20–24. On the whole, however, we do not discern on this record how specific experience in textile engineering and fiber science of a person of ordinary skill would materially alter the outcome at this stage of the proceeding. For purposes of this decision only, we apply Patent Owner’s proposed definition of a person of ordinary skill in the art, except for the requirement of five years of experience in measurement and analysis of coefficient of friction. The level of skill in the art remains an open issue in this proceeding.

Because our determination that Petitioner demonstrates at least one challenged claim meets the threshold for institution (see SAS Inst., 138 S.

“We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard. Luminara Worldwide, LLC v. Liown Elecs. Co., 814 F.3d 1343, 1353 (Fed. Cir. 2016) (“Absent lexicography or disavowal, we do not depart from the plain meaning of the claims.”); In re Am. Acad. Of Sci.

Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). We note that the ’854 patent specification sets forth a definition for the coefficient of friction between the surfaces of the mesh material and the slide surface. Ex. 1001, 4:38–46. As stated above, however, we do not expressly construe any claim term at this stage of the proceeding. Should the parties address the construction of “coefficient of friction” at trial, we will make a determination after the close of evidence and any hearing.” slip op. at 13

Patent Owner responds that “Petitioner and its expert rely on conclusory statements regarding a person of ordinary skill in the art” such that Dr. “Hochwald’s conclusory opinion should be given no weight.” PO Resp. 4–5 (citing Ex. 1002 ¶¶ 21–24). Notwithstanding Patent Owner’s arguments, Dr. Hochwald declares that “[a]ll of the opinions contained in this declaration are based on the documents I have reviewed and my professional judgment, as well as my education, experience, and professional knowledge.” Ex. 1002 ¶ 17. Such documents include the “’098 patent (EX1001), the prosecution history of the ’098 patent (EX1017), the prior art references cited herein, and other Hochwald bases his proposed level of ordinary skill on the relevant documents. Moreover, Patent Owner does not offer a proposed level of ordinary skill in the art or even argue that a different level would result in a different analysis by Dr. Hochwald or any other declarant. See id.

“In any event, even if we generally adopt what Patent Owner refers to as an agreed upon plain and ordinary meaning and construe “detecting a person at the entrance” as limited to “detecting a person at an exterior,” and further construe “exterior” as referring to the exterior of an area defined by some type of a “demarcation line” according to the ’098 patent’s description of Figure 1 (see Ex. 1001, 6:40–50), the Petitioner persuasively shows that the prior art teaches the limitation (including when the “demarcation line” defines the exterior of a building), as discussed further below. Accordingly, it is not necessary to explicitly construe the limitation any further or to construe any other claim terms, because any construction would not impact the analysis of Petitioner’s asserted grounds.

“shows that the ’384 provisional does not contemplate transmitting “video of the person at the entrance” to a “remote peripheral device by which a user of the remote peripheral device may view the video of the person at the entrance,” using “a graphic user interface,” as claim step 1c requires. Disclosure in the ’384 provisional of a generic laptop or other remote peripheral device that may be capable of viewing video in isolation is not possession of the claimed invention. In other words, as Petitioner persuasively shows, “[c]ommunication of actual video to the remote peripheral device was not countenanced in the provisional, and [Patent Owner] fails to identify evidence to the contrary.” Id. at 9. That is, as Petitioner also argues, “[w]ritten description support is not established simply by identifying peripheral devices such as PDAs and laptop[s] in the provisional and arguing that such devices were ‘capable of’ displaying video, nor by the provisional’s disclosure of ‘communications’ between the central computer and said peripheral devices.” Id. at 8–9 (citing Tech. Licensing Corp. v. Videotek, Inc., 545 F.3d 1316, 1331–32 (Fed. Cir. 2008)). Under the rationale and holding of Tech. Licensing Corp., even if “a person skilled in the art might conclude” that the ’384 provisional’s disclosed system is capable of performing the same function of viewing the particular video at a remote peripheral device, this is not enough to show adequate written description. See id. at 1334 (“This evidence persuaded the trial court that a person skilled in the art might conclude that R21 and R26 establishing a level shifted signal [as recited in the ’250 patent claims at issue], but that was all,” and that evidence is insufficient to satisfy written description for a level shifted signal), 1333–34 (“The pertinent question is not whether a person skilled in the art could look at both Figure 3 [from the earlier-filed ’323 application] and Figure 16 [from the ’250 patent at issue] and determine that the resistors in the former perform a similar function to the resistors in the latter. Rather, the issue is whether a person skilled in the art would understand from the earlier application alone, without consulting the new matter in the ’250 patent, that the inventor had possession of the claimed ‘other circuit’ in 1992 when the ′323 application was filed.”). Even if there is a disclosure in the ’384 provisional of a system that merely is capable of providing for the viewing of live streaming or recorded video at the remote peripheral device of “the person at the entrance,” this still is not sufficient written description for claim 1, step 1c. Rather, claim 1 requires “a graphic user interface” (which facilitates and controls the viewing) at “the remote peripheral device,” because it requires “providing a [GUI] to a remote peripheral device by which a user of the remote peripheral device may view the video of the person at the entrance.”14 There is no disclosure in the ’384 provisional for providing a GUI to a remote peripheral device.

“evaluated the subject matter of Riis during examination of the ’624 patent, we agree that Riis was before the Office, as discussed in connection with our analysis of the first part of the Advanced Bionics framework, above. Examiner T presumably was aware of Riis by virtue of having initialed an IDS containing Riis in the ’624 patent’s application and also by virtue of having initialed an IDS containing Riis in the ’067 Application, but Examiner T did not apply Riis in connection with the examination of the ’624 patent. On this record, Patent Owner also fails to show that the claims of the child application leading to the ’624 patent are substantially similar to those of the parent ’814 patent in which Examiner S considered Riis, and, thus, consideration of Riis during the prosecution of the ’814 patent does not equate to consideration of Riis during the prosecution of the ’624 patent. Regarding Patent Owner’s argument (2) that Petitioner fails to sufficiently show how the Examiner erred in evaluating the prior art, we find Petitioner’s arguments demonstrate that Examiner T, the examiner of the ’624 patent, did not apply Riis (or Wypych or Tatarka) during the examination of the’624 patent. As Petitioner argues, the error lies in that “the Examiner failed to consider the relevance of Riis as it applied to the pending method claims,” because although “Riis was considered during examination of the parent ’999 application, Riis was not similarly considered during examination of the ’018 application which led to the ’624 patent.” Pet. 76–77.

However, we disagree with PARC that a person of ordinary skill would have considered the term “assertion” to exclude facts.

And we agree that the two terms have different meanings in claim 1 based on the plain meaning of each term. However, the specification refers to “stor[ing] facts and assertions about a user’s behavior and interests,” which simply appears to identify a single category of data for storage, i.e., “facts and assertions,” without specifying a clear difference between “facts” and “assertions.” See Ex. 1001, 3:21–22.

“Patent Owner fails to identify any statement in the ’384 provisional mentioning “a remote peripheral device configured to . . . communicate with said computerized controller for viewing an image from said video camera” as claimed. Although Patent Owner shows a system that may be configurable to communicate with a computerized controller for viewing an image from a video camera, Patent Owner does not cite to clear support showing that a remote peripheral device is so configured in the ’384 provisional. Consequently, we find Petitioner’s showing sufficient for purposes of institution, although we do not consider this issue closed. Neither party mentions why this issue is important in this case. We assume that it is because the issue of whether Klein is prior art turns on the priority date of the ’581 patent. For purposes of this Decision, Petitioner has shown sufficiently that Klein does constitute prior art. Petitioner’s showing is also sufficient to shift the burden of production going forward to Patent Owner to show that the ’581 patent is entitled to the benefit of the ’384 provisional by demonstrating written description support under § 112 for all limitations of the claims.

Patent Owner contends that Petitioner’s modification of Vaios would require its video camera to incorporate numerous additional components which would destroy Vaios’s video camera and render its local computer system superfluous. Prelim. Resp. 43–47, 52–62. Patent Owner has not explained sufficiently why it would be necessary to transfer all components of the Vaios’s local computer system 12 to its video camera 10.

“The Final Written Decision acknowledged the disclosure in the ’182 Application of the objective of lengthening usable echo train durations while achieving desired image contrast characteristics. Final Dec. 22 (citing Ex. 1014, 4). We concluded this disclosure was similar to the disclosure of the key feature in Purdue Pharma. Id. (citing Purdue Pharma, 230 F.3d at 1327). UVAPF disputes that conclusion, arguing that the comparison with Purdue Pharma is not “meaningful,” because we purportedly overlooked the importance of lengthening the usable echo train duration while achieving comparable image contrast, and the relationship between this “primary objective” and the echo time ratio. Req. Reh’g 8–9. The Final Written Decision, however, specifically considered this “primary objective” described in the ’182 Application—including both the echo train duration and image contrast aspects. Final Dec. 22. We further concluded the alleged relationship between that key feature and the echo time ratio, which is not described in the ’182 Application, was insufficient to direct a skilled artisan to the recited echo time ratio limitations. Id. As we explained, the patent in Purdue Pharma similarly described a key feature and claimed a particular ratio related to that feature, but the court held the written description was inadequate because it failed to describe that ratio or ascribe any particular importance to that ratio. Id. at 20–22 (citing Purdue Pharma, 230 F.3d at 1326–28). The same is true of the claimed echo time ratio and the disclosure of the ’182 Application, which does not identify any such ratio much less describe its significance. Id.

“not have been considered because they were untimely. Req. Reh’g 9–11. GE did not cite the Purdue Pharma case until the Petitioner Reply. See Paper 27, 13–14. We disagree that GE’s arguments were untimely, however, because Purdue Pharma was cited to rebut arguments made by UVAPF in its Patent Owner Response. In the Patent Owner Response, UVAPF argued that a person of ordinary skill would have been able to derive the full range recited for the echo time ratio limitations based on an example provided in the ’182 Application. Paper 21, 55–58. GE argued in the Petitioner Reply that UVAPF’s position is precluded by Purdue Pharma, which held that whether a claimed ratio can be derived from the written description is immaterial if the disclosure does not describe the ratio or direct a person of ordinary skill to the ratio as a part of the invention. Paper 27, 13–14 (citing Purdue Pharma, 230 F.3d at 1328). Thus, Purdue Pharma was cited to respond directly to arguments made by UVAPF in its Patent Owner Response, and GE’s arguments based on Purdue Pharma were not untimely. In addition, UVAPF also contends GE untimely raised its arguments that the ’182 Application does not provide sufficient support for the “at least twice” aspect of the echo time ratio limitations. Req. Reh’g 11–13. To the contrary, GE argued in the Petition that the ’182 Application failed to adequately support the “at least twice” limitation. Pet. 11–12 (“[N]owhere does the ’182 application make a comparison of the [effective echo time] of a pulse sequence derived according to the disclosed method, much less delineate a range with a boundary of ‘at least twice’ that of any other echo time.”).
