“7. Balancing the Fintiv Factors As discussed above, factors 1 and 3–5 each favor denial. Factor 2 is the only factor that favors institution because there is no trial date in the Parallel Proceeding and the evidence presented of a median time-to-trial for civil trials in that district suggests a potential trial date after the statutory deadline for a final written decision in this proceeding. However, Patent Owner also shows that discovery and any dispositive motions will be completed in the Parallel Proceeding well before the statutory deadline for a final written decision in this proceeding, which presents a risk of duplicated efforts given the unmitigated overlap in issues between proceedings. On balance, considerations concerning an uncertain trial date in the Parallel Proceeding under Factor 2 do not outweigh the more substantial reasons identified under the other Fintiv Factors. Thus, considering all of the factors holistically, we find on balance that the factors on this unique record weigh in favor of discretionary denial of the Petition. Accordingly, we exercise discretion to deny institution under 35 U.S.C. § 314(a).” slip op. at 15

- Expert testimonyPetitioner expert discountedDecided for patent owner
“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)).

RulingsFinal written decision- Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) appliesDecided for patent owner
“We determine that the evidence of record overcomes the presumption that § 112, para. 6 does not apply because “thrust-bearing element” does not recite sufficiently definite structure in this case. See, e.g., Pet. 22 (the term is not used here according to its common meaning). First, the word “element” is a “[g]eneric term[]” or “verbal construct[]” often “used in a claim in a manner that is tantamount to using the word ‘means’” because it does not “connote sufficiently definite structure.” Williamson, 792 F.3d at 1350. We find nothing in the ’121 patent or elsewhere in the record suggesting that “element” in the term “thrust-bearing element” should be considered other than a generic placeholder term. Second, although the term “thrust bearing” may connote certain structure, “thrust-bearing element” does not. A “thrust bearing” is “a well-known term of art in engineering and is ‘a bearing which sustains axial loads and prevents axial movement of a loaded shaft.’” Ex. 1003 ¶ 46 (citing Ex. 1017, 2147). “The balls of traditional thrust bearings are positioned inline with the axial force, as thrust bearings are designed specifically to transmit axial load.” Id. Here, however, “thrust-bearing” is hyphenated, and is therefore a phrasal adjective modifying “element” rather than the noun phrase “thrust bearing.”8 Further, there are “substantial differences”” slip op. at 15

“We largely agree with Petitioner. “[S]tructure disclosed in the specification is ‘corresponding’ structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim.” B. Braun Med. Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed.Cir.1997). The Specification of the ’121 patent “clearly links or associates” two components with the function of bearing axial thrust from the sowing disc: shaft 27 with flanging 30, and thrust-bearing plate 31. Ex. 1001, 3:25–35. Thrust-bearing plate 31 is expressly described as “bear[ing] on that surface of the disc which faces seal 24 . . . in order to withstand at least some of the axial load produced by the disc 16 on the seal 24. Ex. 1001, 3:28–31. Rotatably-mounted shaft 27 with flanging 30 is “fixed” to thrust-bearing plate 31 and therefore bears the axial load from the disc via the thrust-bearing plate. Id. at 3:25–28.10 10 Drive element 32 is described as part of thrust-bearing element 26 and permits thrust-bearing element 26 to be driven in rotation with sowing disc 16. Ex. 1001, 3:36–40. It is not described as bearing any axial load, however. Further, it is not necessary for the thrust-bearing element to rotate with the sowing disc for that element to bear axial load from the sowing disc. See id. at 3:58–59 (“Provision is also made for the thrust-bearing element 26 to be made idle and not driven in rotation by the [drive] shaft 20.”). Ultimately, however, whether drive element 32 is properly considered as part of the corresponding structure is not relevant to the outcome of this case. We disagree with Patent Owner that bearings 28 and seat 29 should be considered corresponding structure. The Specification does not associate these structures with any axial load-bearing function. Instead, bearings 28 and seat 29 are described as the means by which, and the location in which, shaft 27 is rotatably mounted. Ex. 1001, 3:25–27. Regardless, whether or not bearings 28 and seat 29 are considered corresponding structure does not affect the outcome of this case. In summary, we construe “thrust-bearing element” as a means-plus- function claim term under 35 U.S.C. § 112, para. 6. Its recited function is to bear thrust, or more specifically to “withstand at least some of the axial load produced by the disc on the seal.” The structure described in the Specification as corresponding to this function is shaft 27 with flanging 30, and thrust-bearing plate 31. We construe the limitation as directed to this structure, and equivalent structures.” slip op. at 21

“The question is not whether the patentee disclaimed coverage over structures in which the thrust-bearing element is not located entirely in the movable portion of the housing. Instead, we must simply ascertain what the patentee meant by “supported rotatably in the movable portion.” To answer this question, we look to the Specification, which “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315. “The construction that stays true to the claim language and most naturally aligns with the patent’s description of the invention will be, in the end, the correct construction.” Id. at 1316. Here, it is undisputed that in the sole embodiment described by the ’121 patent, the thrust-bearing element is supported by and entirely within the movable portion of the housing. Ex. 1001, Figs. 1, 2; Pet Post-Hearing Resp. 1; PO Post-Hearing Resp. 2. Construing “in the movable portion” to require the thrust-bearing element to be entirely within the movable portion both “stays true to the claim language and most naturally aligns” with the sole disclosed embodiment. Such a construction does not import the word “entirely” from the sole embodiment into the claims because the construction “arises from the claim language itself.” See SharkNinja Operating LLC v. iRobot Corp., 2024 WL 1132219, *2–*3 (Fed. Cir. 2024) (construing “primary brush assembly disposed within the round housing perimeter” to require that the primary brush assembly be “entirely within” the round housing perimeter is not an improper incorporation of “entirely” from embodiments into the claims because the construction “arises from the claim language itself”).

Petitioner does not contend, much less show, that these components are supported rotatably entirely in the movable second housing member 90. On the contrary, of the three components constituting VenHuizen’s thrust-bearing element, all of retaining hub 56 and most of shaft 55 are located in the fixed portion of the housing (first housing member 50), not the movable portion 90. See Ex. 1001, Fig. 6. Only handle 58 is ever located in the movable portion (when the fixed and movable portions are joined together). See id.

“We disagree with Patent Owner’s arguments because here Petitioner is not relying on some other disclosure to fill a missing limitation absent from Collinge, but is instead relying only on Collinge and the knowledge a person of ordinary skill in the art would possess when appreciating the teachings of Collinge. Petitioner is not suggesting Collinge needed to be modified to add the use of an APDU, but, rather, that Collinge’s disclosure already contemplated it based on the well-known background of the art. Petitioner shows by a preponderance of the evidence that “the Collinge Provisionals state the disclosures therein are intended to be used in a ‘standard’ PayPass transaction,” and that a person of ordinary skill in the art would have considered “the PayPass Specification (and EMV Specifications, with which the PayPass Specification complies) when reading Collinge.” Pet. Reply 8 (citing Ex. 1009, 8, 14–15, 22–23; Ex. 1050 ¶ 22). in a “standard” PayPass transaction and that a person of ordinary skill in the art would have known, at a minimum, that it would have been obvious from Collinge that the “first set of data” (i.e., the encrypted payload in Collinge) would have been “usable” by the application of Collinge “to formulate an application protocol data unit response,” as required by limitation [1.C]. Petitioner further demonstrates how Collinge discloses that the “first set of data” was “useable by the application to formulate” an APDU response in addressing limitation [1.E–3], which specifically requires “generating a response.” See Pet. Reply 11 (explaining that “[d]etails of how [the encrypted payload] is used to formulate an APDU response are explained where that is separately claimed”); see also id.

“In sum, Patent Owner asserts that the precise teachings of the asserted secondary references do not amount to detecting electrical conduction through the posterior tibial nerve. That argument does not consider that Petitioner relies on a combination in which Svihra’s approach is modified by the secondary references such that Svihra’s stimulation of the PTN is detected and used to automatically control the stimulation parameters. Pet. 21–28. As discussed, we view the references’ disclosures as supporting Petitioner’s contentions. f. Summary We conclude that Petitioner has identified sufficient reason that skilled artisans would have modified Svihra’s approach to incorporate the systems and techniques of Mann, DiLorenzo, Gerber, and Bourget, and that the asserted combination renders obvious claim 1’s limitations. Accordingly, this ground supports institution.” slip op. at 30

“35 U.S.C. § 325(d) because Amarenco and Mann previously were presented to the Office during prosecution of the ’742 patent. See Prelim. Resp. 17–18. According to Patent Owner, Petitioner has identified additional references that “supposedly teach[] only some of what was missing—stimulation of a branch of the posterior tibial nerve but not to treat overactive bladder or incontinence.” Id. at 18. Patent Owner’s argument is flawed for two reasons. First, neither Svihra nor Ponsford were previously presented to the Office. Because Patent Owner does not argue that we should deny institution of Petitioner’s Svihra-based ground under § 325(d), and because that ground relies on a combination of art not previously presented, Patent Owner’s § 325(d) argument is unpersuasive. In that regard, we determine that even if we were to conclude the Amarenco-based ground warranted discretionary denial, the Svihra-based ground would not be subject to such denial and may alone justify institution. See USPTO, SAS Q&As (June 5, 2018) at D1.11 Additionally, for the Amarenco-based ground, Petitioner relies on a combination including prior art that was not previously presented, and Patent Owner does not show that additional prior art is cumulative to art presented during prosecution. We determine that Petitioner’s Amarenco-based ground 11 Available at: https://www.uspto.gov/sites/default/files/documents/ sas_qas_20180605.pdf is not substantially the same as one previously presented to the Office. Thus, we decline to discretionarily deny institution under § 325(d).” slip op. at 8

“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.

“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
