“We are not persuaded, on this record, that Petitioner adequately establishes that Khatibi discloses a CTE in the claimed range of 16 to 22 µm/(m·°C.). Petitioner’s argument that Khatibi’s reported values meet this claim limitation are based solely on Dr. Randall’s testimony that Khatibi’s measurement method would produce results that would not significantly differ from results determined using the claimed method. See Pet. 16–18 (citing Ex. 1003 ¶¶ 56–60). Dr. Randall’s testimony, however, is largely conclusory and unsupported by adequate explanation and/or objective evidence. For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added). to little weight. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); Xerox Corp. v.

Mova Pharm. Corp., 225 F.3d 1306, 1311 (Fed.

“second surfaces of the electrolytic copper foil ranges from 3 to 92.” Ex. 1001, 13:62–63. Petitioner contends that “Kim teaches that the electrolytic copper foil (e.g., untreated or treated copper foil) having Rz less than 2 µm is advantageous toward battery efficiency and performance,” and, similarly, Griesi describes the use of untreated electrolytic copper foil with an Rz value less than 2 µm in printed circuit boards that are compatible with secondary batteries. Pet. 58–59 (citing Ex. 1012, claim 2, ¶¶ 13, 25, 27; Ex. 1003 ¶ 157). In particular, Petitioner notes that Griesi’s Figure 3.16 describes an “Rz value of 1.2 µm.” Id. at 59 (citing Ex. 1015, 53–54; Ex. 1003 ¶ 158). Petitioner asserts that “Dr. Randall explains that a POSITA would have also recognized another surface roughness-related parameter, Rpc, in Griesi as a potentially useful parameter that can be optimized to further enhance uniformity or generally improve Kim’s copper foil surface, for example, to prevent wrinkles or achieve other advantageous effects.” Id. (citing Ex. 1003 ¶ 159). Although Dr. Randall demonstrates that Griesi’s Pc (or Rpc) value is 19.2 over a 4 mm sampling length (Ex. 1003 ¶ 155), Petitioner does not contend that Griesi addresses this value, or indicates any benefit that might be derived from its use. Instead, Griesi’s Pc value appears to be an incidental finding, which is not discussed or analyzed in the reference. See incidental, unexamined finding would lead a POSITA to import Griesi’s Pc value into Kim’s copper foil, absent a hindsight desire to reconstruct the claimed invention. As such, Petitioner’s arguments with respect to Kim and Griesi are not persuasive. See Cheese Sys. Inc. v. Tetra Pak Cheese and Powder Sys., Inc., 725 F.3d 1341, 1352 (Fed. Cir. 2013) (“Obviousness cannot be based on the hindsight combination of components selectively culled from the prior art to fit the parameters of the patented invention.” (internal quotations marks omitted)).

“Because of Patent Owner’s shifting definitions of the education and experience level of the ordinarily skilled artisan, it is unclear on the complete record what precise definition Patent Owner and Dr. Senkevitch are applying when arguing the skilled artisan’s capabilities.

Moreover, as Petitioner correctly points out, the ʼ087 patent expressly teaches that the precise conditions for forming a protective polymeric coating “will vary depending upon factors such as, without limitation, the nature of the monomer compound, the crosslinking agent, the substrate, as well as the desired properties of the coating” and that such “conditions can be determined using routine methods.” Ex. 1001 15:1–15:5 (emphasis added); Pet. Reply 17.

“We disagree with Patent Owner. Although the claims of the ʼ087 patent recite obtaining the protective cross-linked polymeric coating “by exposing the device or component to a plasma,” the field of endeavor analysis in an analogous art inquiry does not exclusively turn on the claims at issue, but rather takes account of the entirety of a patent’s disclosure. See In re Bigio, 381 F.3d 1320, 1326 (Fed. Cir. 2004) (explaining that “the PTO must show adequate support for its findings on the scope of the field of endeavor in the application’s written description and claims” (emphasis added)); In re Mettke, 570 F.3d 1356, 1359 (Fed. Cir. 2009) (rejecting an argument that the field of endeavor was limited to a claimed “Internet terminal” when “the specification describes various communication media, including facsimile machines and email, as related to the invention.”). This is significant here because the ʼ087 patent discloses that “[t]he … invention relates to protective coatings” and specifically “relates to protective coatings for electronic or electrical devices and components thereof, and methods of forming such coatings.” Ex. 1001, 1:14–17. Based on this disclosure, we find that the ʼ087 patent’s field of endeavor relates to “protective coatings for electronic or electrical devices and components thereof” broadly, not just those formed on such devices or components via a plasma polymerization process as asserted by Patent Owner. Id. Although Cohen does not explicitly disclose that its crosslinked polymers constitute a “protective coating,” Cohen does disclose that its “copolymerizable mixture can be cast into films” (Ex. 1004, 2:61–62), that the polymerization can “effected in situ,” and that the polymers may be used in “numerous” electrical applications (id. at 5:17–25). Tr. 8:9–10:2, 27:2– 21; see Pet. Reply 5 (explaining how “Cohen described insulating polymers that could be applied as films and be used to protect substrates including cables and electrical coils.” (citing Ex. 1004, 2:60–63, 5:13–25)). These disclosures suggest strongly that Cohen’s crosslinked polymers––if cast into a film or formed in situ on an electrical device or component––would serve as a protective coating on that electrical device or component, even though Cohen does not expressly refer to its crosslinked polymers ipsis verbis as a “protective coating.” Thus, we find that Cohen is within the field of endeavor of the ʼ087 patent.” slip op. at 15

Patent Owner’s argument is flawed for two reasons. First, neither Svihra nor Ponsford were previously presented to the Office.

“justification for requiring a POSITA to have both an engineering degree and a medical degree. We agree, insofar as Petitioner has not clearly set out any particular explanation or evidence in support of its dual-degree requirement. In all other respects, we note that the parties’ proposed definitions are largely similar. Because we determine that Patent Owner’s proposed definition is reasonable and consistent with the ’028 patent and the cited art, we adopt Patent Owner’s definition for purposes of this Decision.

“Based on our review of the Petition, Petitioner explains that a driving motivation for a POSITA to modify Lundahl to include Larsen’s five panels is “to increase the flexibility of the device to ensure the light panels could be maintained at a distance of 2-4′′ from surface of the treatment area, whether the face, arm, or back, etc.” Pet. 29 (emphasis added). As Lundahl’s device is not flexible, and such flexibility would improve its ability to treat areas other than an average sized face, we determine, at this stage in the proceeding, that this motivation for the combination is sufficient.” slip op. at 20

“would have been motivated to modify Lundahl’s device by incorporating Larsen’s use of LEDs on the surface of the light applicators in place of Lundahl’s fluorescent tubes with a reasonable expectation of success. Prelim. Resp. 55. Patent Owner argues that Petitioner’s modification is based on improper hindsight bias because “Petitioner cherry-picks Larsen’s LEDs (together with the five panels) and purports to arrange them according to the [sic] ‘the uneven spacing’ of Lundahl’s fluorescent tubes.” Id. at 56 (citing Pet. 46–49; Ex. 1015 ¶¶ 175–80). According to Patent Owner, “Petitioner cannot on the one hand argue that a ‘POSITA would have understood that Larsen’s applicator is configured to uniformly illuminate a treatment surface of the patient,’ while on the other ignore Larsen’s teaching that the ‘light sources 17 are placed in regular row arrangements.’” Id. Patent Owner asserts that Petitioner’s proposed modification “mish-mashes aspects of Lundahl and Larsen ([while] avoiding the overall teachings of [challenged] claims.” Id. at 56–57. As discussed above, based on our consideration of the current record, Petitioner has provided sufficient motivation for employing Larsen’s flexible five panel configuration. These panels in Larsen already use LEDs as their light source. So, in our view, Petitioner’s incorporation of the five panels includes the lighting source, i.e., LEDs, for those panels taught by Larsen. Further, we note that Petitioner has persuasively asserted that a skilled artisan would have been motivated to use Larsen’s LEDs as they are more cost-efficient and last longer.

- Skill levelSkill level petitioner adoptedDecided for petitioner
“Petitioner, relying on the testimony of Mr. Brown, contends that a person of ordinary skill in the art (“POSA” or “POSITA”) as of the relevant date would be either: (1) a person with a B.S. in engineering or an equivalent field, with two-four years of academic or industry experience in aspiration embolectomy and thrombectomy or comparable industry experience who would, where appropriate, work or consult with others, including a physician, to develop embolectomy or thrombectomy devices; or (2) an interventional neurosurgeon with at least three years of experience developing and/or using medical devices in embolectomy or thrombectomy procedures, and who would, where appropriate, work or consult with others, including an engineer, to develop such a medical device. Pet. 11 (citing Ex. 1005 ¶ 48). Petitioner also contends that, “[a] person with less education but more relevant practical experience, or more relevant education but less practical experience, may also meet this standard.” Id. Patent Owner states that for purposes of its Preliminary Response, it accepts Petitioner’s proposed definition of POSA, but “reserves the right to propose its own description of a POSA if the Board institutes review.” Prelim. Resp. 8 n.3. For purposes of this Decision, we adopt Petitioner’s characterization because it is consistent with the level of skill in the art at the time of the invention as reflected by the ’402 patent and the cited prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“Petitioner provides a proposed construction for the term “[limited/limiting] to a positive amount of exit flow” recited in claims 3, 4, 13, and 15, as “the maximum permitted amount of positive exit flow in the distal direction, including no exit flow.” Pet. 15–16. Patent Owner asserts that “Petitioner’s proposed construction of ‘a positive amount of exit flow’ as ‘including no exit flow’ is plainly wrong.” Prelim. Resp. 9 (citing Pet. 15–16). Patent Owner also asserts that to the extent Petitioner “view[s] the claim term ‘flow in and out’ as encompassing only flow in or no flow at all, that would be plainly wrong too.” Id. Having evaluated the arguments and evidence before us on this record, we determine that construction of “[limited/limiting] to a positive amount of exit flow” is not necessary for purposes of this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”)). Turning to a different claim term, we note that neither party provided an explicit construction for the limitation in claim 1 of “control[ling] fluid address the proper claim construction for this term and to specifically discuss what is encompassed by “flow . . . out from the distal end.” We note that in the related cases (IPR2021-01466 and IPR2022-00608), we construed the term, “forward flow” to mean “an amount of liquid in the lumen that exits the distal end in the distal direction that is greater than 6 microliters of fluid.” Ex. 2007, 15; Ex. 2011, 13–14. Upon review of the parties’ arguments and the evidence of record, we determine that no terms require express construction for purposes of this Decision.

- Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted
“c) Analysis On the current record, we are persuaded that Petitioner has demonstrated a reasonable likelihood that the subject matter of claim 1 would have been obvious over the combined disclosures of Yang and Mullins. First, Patent Owner asserts that Yang does not disclose the limitation of “a controller . . . to control fluid flow in and out from the distal end.” Prelim. Resp. 21– 32. On the current record, we agree with Patent Owner that introducing a positive pressure pulse such as through the water hammer effect does not necessarily mean that there will be an overall distal end. See Ex. 2001 ¶¶ 53–54; Ex. 2005 ¶ 60; Ex. 2007, 51 n.12. This is especially true if an overall vacuum state is maintained in the catheter. See Ex. 2001 ¶ 56; Ex. 2007, 43; Ex. 2010, 125:11–18. Further, on the current record, we credit the testimony of Patent Owner’s declarant, Mr. Culbert, that to have flow out of the catheter’s distal end when it is in a patient, the pressure in the catheter needs to exceed mean arterial pressure. See Ex. 2001 ¶ 59; Ex. 2010, 126:15–21. Therefore, on the current record, we agree with Patent Owner that Yang may not explicitly disclose flow out from the distal end of the catheter. Whether Yang alone renders this limitation obvious may be explored further on a full trial record; however, because this limitation appears to be taught by Mullins and Petitioner has shown on this record that a POSA would have been motivated to combine the disclosures of Yang and Mullins, we are sufficiently persuaded that Petitioner has met its burden to show a reasonable likelihood that this limitation is rendered obvious by the combined disclosures of Yang and Mullins.” slip op. at 18
