      “The invention, a reciprocating massage device, is in a predictable field, namely the electro-mechanical arts. Also, there is no evidence that the recited quick-connect system is complex, even considering Patent Owner’s alleged understanding of it. Rather, Dr. Pratt testifies that many different types of connectors, whether they require alignment or not, were known. Ex. 1002 ¶¶ 54–58. Given the predictability of the electro-mechanical arts and lack of complexity of the recited quick-connect system, a low level of detail is required to satisfy the written description requirement. See RAI Strategic Holdings, Inc. v. Philip Morris Prods. S.A., 92 F.4th 1085, 1090 (Fed.

      “Contrary to Petitioner’s assertion, the Specification provides guidance as to what amount of deviation from a perfect cylinder is still “substantially cylindrical.” The Specification describes: Quick-connect system 600 includes a piston 602 that has a hollow-end bore 608 for receiving the shaft 621 of a massaging head 620. Located within the bore 608 of piston 602 is a cylindrical seat 604. Cylindrical seat 604 retains a magnet 606. Magnet 606 is illustrated with its north pole located flush with the seat and facing toward the opening in bore 608. Massaging head 620 includes a shaft 621 having a cylindrical pocket 622 at the distal end. Located within the cylindrical pocket 622 is a magnet 624. Magnet 624 is positioned so that its south pole is located at the distal end of shaft 621. Accordingly, when the shaft 621 of massaging head 620 is slid into opening in bore 608, the magnets 606 and 624 are attracted to one another and magnetically hold massaging head 620 firmly in place. Ex. 1001, 6:57–7:3. In view of the description of quick-connect system 600, the Specification sets forth a standard for ascertaining whether the bore and the seat located within the bore are “substantially cylindrical.” To wit, the bore and the seat within the bore are “substantially cylindrical” when the massaging head and magnet are respectively received therein so that the magnet in the seat and the magnet in the pocket of the massaging head can magnetically hold the massaging head firmly in place. Furthermore, Dr. Pratt testifies that “[m]agnetic connectors comprise a magnet on at least one of the two objects to be joined. These types of connectors are ubiquitous even today for driving threaded fasteners.” Ex. 1002 ¶ 56. Dr. Pratt also testifies that a POSITA would understand how to take into account certain variances, like runout. Ex. 2033, 25:3–17. Dr. Pratt’s testimony shows that magnetic connectors are well known and that a POSITA would be able to determine whether the bore and the seat within the bore were “substantially cylindrical” for a secure connection of the massaging head. In view of the foregoing, Petitioner has not persuaded us that the claim term “substantially cylindrical” recited in claims 13–16 fails to inform, with reasonable certainty, the shapes of the bore and the structure within the bore. Petitioner has not proven, by a preponderance of the evidence, that any of claims 13–16 are unpatentable under 35 U.S.C. § 112(b) as indefinite.” slip op. at 19

      “The invention, a reciprocating massage device, is in a predictable field, namely the electro-mechanical arts. Also, there is no evidence that the recited quick release connector is complex, even considering Patent Owner’s alleged understanding of it. Rather, Dr. Pratt testifies that a POSITA would be able to recognize a quick release connector for a particular application. According to Dr. Pratt, A person of ordinary skill in the art would consider a number of factors, depending on the context and specific application of the connector, to determine whether a connector provides a “quick release.” Such factors could include whether the connector is designed to manually and easily connect and disconnect two objects, and whether tools are necessary to do so. Other factors to be considered may be based on the specific application or operating environment. Ex. 1002 ¶ 58. Given the predictability of the electro-mechanical arts and lack of complexity of the recited quick release connector, a low level of detail is required to satisfy the written description requirement. See RAI Strategic Holdings, Inc. v. Philip Morris Prods. S.A., 92 F.4th 1085, 1090 (Fed.

Conclusion for Written Description For the reasons set forth above in sections II.C.1–3, Petitioner has not persuaded us that any aspect of claim element 34[e] lacks written description support.

      “Contrary to Petitioner’s assertion, the Specification provides guidance as to what amount of deviation from a perfect cylinder is still “substantially cylindrical.” The Specification describes that quick-connect system 600 includes two magnets with opposite poles facing each other: magnet 606 in the distal end of piston 602 and magnet 624 located in cylindrical pocket 622 of massaging head 620. Ex. 1001, 6:57–67, Figs. 6, 6A. The Specification further describes that “when the shaft 621 of massaging head 620 is slid into opening in bore 608, the magnets 606 and 624 are attracted to one another and magnetically hold massaging head 620 firmly in place.” Id. at 6:67–7:3. In view of the description of quick-connect system 600, the Specification sets forth a standard for ascertaining whether the pocket is “substantially cylindrical.” To wit, the pocket is “substantially cylindrical” when the pocket receives a magnet therein so that the magnets can magnetically hold the massaging head firmly in place. Furthermore, Dr. Pratt testifies that “[m]agnetic connectors comprise a magnet on at least one of the two objects to be joined. These types of connectors are ubiquitous even today for driving threaded fasteners.” Ex. 1002 ¶ 55.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed petitioner constructionDecided for petitioner

      “as adopted by the Board in the Institution Decision. The ’253 patent explicitly defines this term, stating: The term “forward flow” is used herein to define an amount of liquid in the lumen 662 that exits the distal end 664 in a distal direction. Forward flow is defined as greater than 6 microliters of fluid (approximately 1 mm of catheter length of ID 0.071″=5.7 μL). Ex. 1001, 38:18–23 (emphasis added). Moreover, in discussing problems with the prior art systems, the ’253 patent states that “[w]hen positive pressure exists at the distal end of the lumen, liquid from inside the lumen exits out from the distal end of the catheter in a distal direction. This is referred to as forward flow.” Id. at 3:8–11. In the ’253 patent, the patentee acted as its own lexicographer as evidenced by usage of language such as “is used herein to define,” “is defined,” and “is referred to as,” to discuss “forward flow.” We find that the definition of “forward flow” in the ’253 patent specification would provide a person of ordinary skill with “reasonable clarity, deliberateness, and precision” as to the meaning of the term. See Paulsen, 30 F.3d at 1480; see also Ex. 1034 ¶¶ 13–14. Thus, we construe 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.” We disagree with Patent Owner’s contention that our construction imports limitations from a single embodiment into the claims. As explained above, the ’253 patent clearly defines the term “forward flow” and this definition is not limited to a single embodiment. In fact, the ’253 patent indicates that, while “[f]orward flow is defined as greater than 6 microliters of fluid . . . [l]ess forward flow is also included in this definition.” Ex. 1001, 38:21–24. The ’253 patent specifies that “the amount of forward flow can be restricted to no greater than 2 microliters or, in a particularly beneficial embodiment, forward flow is approximately zero microliters.” Id. at 38:24– 29. This language indicates that our construction encompasses multiple embodiments from the ’253 patent. We also disagree with Patent’s Owner’s proposed construction of “forward flow” because it is not supported by the ’253 patent specification. Patent Owner contends that “there is ‘no forward flow’ until the full extent of the distal portion” exits the distal end and thus forward flow is prevented when only less than “the full extent of the distal portion” exits the distal end. PO Resp. 9 (emphasis omitted). To adopt Patent Owner’s proposed construction, we would have to essentially ignore the ’253 patent’s express definition of this term. Further, there is no support in the ’253 patent specification for “full extent” or “fully exiting.” We also agree with Petitioner that Patent Owner’s construction effectively eliminates the concept of preventing forward flow because, as Patent Owner acknowledges, it could allow, for example, 20 milliliters of fluid to exit the catheter, which could displace the thrombus into the patient’s vasculature, a problem that the ’253 patent seeks to avoid. See PO Resp. 10–12 (citing Ex. 2014 ¶¶ 48–51); Pet. Reply 8–9 (citing Ex. 1034 ¶¶ 14–15).” slip op. at 13

      “As discussed above, we construe “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.” Thus, for the ’011 provisional to provide support for this limitation, the provisional must demonstrate that the inventors had possession of preventing greater than 6 microliters of fluid out of the distal end of the catheter. While Patent Owner points to disclosures from the ’011 provisional application that describe the desire to have “a minimal amount of momentum transfer from the fluid column to the stuck clot to unstick the clot sufficiently” and “[t]he exiting movement of fluid [being] limited to a specific volume and/or pressure and is automatically and precisely controlled” to prevent the “possibility of overshooting,” these disclosures would not convey to one of ordinary skill in the art that the inventors were in possession of a device that limited forward flow to no greater than 6 microliters of fluid. PO Resp. 35 (citing Ex. 1003 ¶¶ 15, 16, 138). Patent Owner also contends that the ’011 provisional application provides “multiple examples of liquid flow exiting the distal end of the catheter such that no forward flow occurs, such as 1 microliter or 0.5 mm of column shift.” PO Resp. 36–37 (citing Ex. 1003 ¶ 91). However, the disclosure cited by Patent Owner provides ranges of liquid flow of “approximately 0.001 ml to approximately 1.0 ml, in particular, approximately 0.1 ml to approximately 0.5 ml” and exemplary length of shift distances of “approximately 0.5 mm to approximately 30 mm, in particular, approximately 0.5 mm to approximately 15 mm.” Ex. 1003 ¶ 91. There is nothing in the ’011 provisional application that specifically directs the person of ordinary skill to the portions of these ranges that fall within the ’253 patent’s definition of “forward flow” (i.e., no greater than 6 microliters of fluid). In fact, the majority of the cited ranges are greater than 6 microliters, going all the way up to 1,000 microliters, such that there would be forward flow in these examples. See Ex. 1034 ¶ 25; Purdue Pharma, 230 F.3d at 1326–27 (“[O]ne cannot disclose a forest in the original application, and then later pick a tree out of the forest and say here is my invention. In order to satisfy the written description requirement, the blaze marks directing the skilled artisan to that tree must be in the originally filed disclosure.”); Fujikawa v. Wattanasin, 93 F.3d 1559, 1571 (Fed. Cir. 1996). Further, we note that the ’253 patent differentiates between embodiments that allow forward flow and embodiments in which no forward flow occurs. See Ex. 1001, 32:58–60, 37:19–22; Pet. Reply 10–11. For example, the ’253 patent describes an embodiment in which the “momentum causes a small amount of fluid to move through the distal portion of the catheter [] and create a small distal movement of the clot.” Ex. 1001, 32:47– 51. This same embodiment is disclosed in the ’011 provisional application. Compare Ex. 1003 ¶ 126 with Ex. 1001, 32:16–60. The ’253 patent describes this disclosure as an “exemplary embodiment” in which the “flow of fluid forward . . . is intentional, which is in contrast to other exemplary embodiments herein where substantially no forward flow occurs.” Ex. 1001, 32:57–60; see also, id. at 37:19–22 (“Turning now to embodiments . . . without the forward flow”).8 The ’011 provisional application does not include the subsequent embodiments from the ’253 patent that are described as being “without the forward flow.” See Ex. 1005 ¶ 68; Ex. 1034 ¶¶ 22–23. This further demonstrates that the ’011 provisional application does not support the limitation of “prevent[ing] forward flow.” We also note that the ’011 provisional application does not contain adequate support for the limitation of “substantially prevent[ing] forward flow” even under Patent Owner’s proposed construction. While the ’011 provisional discloses “controlling the distal movement of the fluid column” (Ex. 1003 ¶¶ 15, 16), this does not support Patent Owner’s assertion that the ’011 provisional teaches that “the distal portion of the fluid column is substantially prevented from fully exiting the distal end.” PO Resp. 35–36. For example, as discussed above, the ’011 provisional application discloses permitting distal flow of up to 1,000 microliters, which would likely exceed the amount that could be characterized as the full distal portion. Ex. 1003 ¶ 91; Ex. 1034 ¶ 25.

      “Based on the above, we determine that, for prior-art determinations under AIA § 102, “there is no need to evaluate whether any claim of [a reference] patent document is actually entitled to priority or benefit under 35 U.S.C. 119, 120.” MPEP § 2154.01(b) (emphasis added). Rather, under the AIA, a reference patent document need only meet the “ministerial requirements” of §§ 119 and 120, and the provisional or other earlier application(s) to which the reference patent document claims a right of priority must “describe[] the subject matter” relied upon in the reference patent document as prior art. 35 U.S.C. § 102(d)(2). Patent Owner has not contested that Teigen meets the procedural requirements for claiming priority to the ’712 patent or the ’095 PCT application. Teigen also appears to meet the ministerial requirements for claiming priority to the provisional applications because it properly claims the benefit of these applications, the ’095 PCT application was filed co-pending with the provisional applications, and the applications share common inventors.

Although we agree with, and have primarily adopted Patent Owner’s definition for an ordinarily skilled artisan in this proceeding, our analysis and conclusions herein would not change even under Petitioner’s definition.

      “as adopted by the Board in the Institution Decision. The ’883 patent explicitly defines this term, stating: The term “forward flow” is used herein to define an amount of liquid in the lumen 662 that exits the distal end 664 in a distal direction. Forward flow is defined as greater than 6 microliters of fluid (approximately 1 mm of catheter length of ID 0.071″=5.7 μL). Ex. 1001, 36:18–23 (emphasis added). Moreover, in discussing problems with the prior art systems, the ’883 patent states that “[w]hen positive pressure exists at the distal end of the lumen, liquid from inside the lumen exits out from the distal end of the catheter in a distal direction. This is referred to as forward flow.” Id. at 2:62–65. In the ’883 patent, the patentee acted as its own lexicographer as evidenced by usage of language such as “is used herein to define,” “is defined,” and “is referred to as,” to discuss “forward flow.” We find that the definition of “forward flow” in the ’883 patent specification would provide a person of ordinary skill with “reasonable clarity, deliberateness, and precision” as to the meaning of the term. See Paulsen, 30 F.3d at 1480; see also Ex. 1030 ¶¶ 13–14; Ex. 2001 ¶¶ 53, 62.

      “As discussed above, we construed “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.” Thus, for the ’011 provisional to provide support for this limitation, the provisional must demonstrate that the inventors had possession of preventing greater than 6 microliters of fluid out of the distal end of the catheter. While Patent Owner points to disclosure from the ’011 provisional application which describes “a minimal amount of momentum transfer from the fluid column to the stuck clot to unstick the clot sufficiently” and “[t]he exiting movement of fluid [being] limited to a specific volume and/or pressure and is automatically and precisely controlled” to prevent the “possibility of overshooting,” it would not convey to one of ordinary skill in the art that the inventors were in possession of a device that limited forward flow to no greater than 6 microliters of fluid. PO Resp. 33 (citing Ex. 1003 ¶¶ 16, 138). Patent Owner also contends that the ’011 provisional application provides “multiple examples of liquid flow exiting the distal end of the catheter such that no forward flow occurs, such as 1 microliter or 0.5 mm of column shift.” PO Resp. 34 (citing Ex. 1003 ¶ 91). However, the disclosure cited by Patent Owner provides ranges of liquid flow of “approximately 0.001 ml to approximately 1.0 ml, in particular, approximately 0.1 ml to approximately 0.5 ml” and exemplary length of shift distances of “approximately 0.5 mm to approximately 30 mm, in particular, approximately 0.5 mm to approximately 15 mm.” Ex. 1003 ¶ 91. There is nothing in the disclosure of the ’011 provisional application that specifically directs the person of ordinary skill to the portions of these ranges which fall within the ’883 patent’s definition of no “forward flow” (i.e., no greater than 6 microliters of fluid). In fact, the majority of the cited ranges are greater than 6 microliters, going all the way up to 1,000 microliters, such that there would be forward flow in these examples.

See 35 U.S.C. §§ 100(i)(1)(B), 102(a)(2), 102(d)(2); MPEP § 2154.01(b). USPTO guidance also indicates that AIA § 102 prior-art reference effective-filing-date determinations differ from pre-AIA law.

Such a component is described by the ’400 patent as the RFID tag. See Ex. 1006, Fig. 5 (element 74).

This is the case here where Mosgrove’s wireless communication system exists already and is merely redirected. “[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” Id. at 417. Further, “any need or problem known in the field of endeavor at the time of invention and addressed by the patent can provide a reason for combining the elements [of the prior art] in the manner claimed.” Id. at 420. This is the case here where the techniques of Harold illuminate an advantage to be had using Mosgrove’s existing system (or a slightly modified Mosgrove system). We find a reason existed to combine and modify the prior art: efficiency and streamlining. See Dystar Textilfarben Gmbh & Co. Deutschland KG v. C.H. Patrick Co., 464 F.3d 1356, 1368 (Fed. Cir. 2006) (making things stronger, cheaper, cleaner, faster, lighter, smaller, more durable, or more efficient are universal motivators to combine/modify prior art). And, as Mosgrove’s disclosed key containers have wireless communication capability, simply specifying that the communications will be between the key container and the computer rather than between the key container and keypad is no technological leap. It would have required only the use of known components and techniques to yield predictable results, and we find there would have been a reasonable expectation for success.

      “ORDINARY SKILL IN THE ART Petitioner proposes that a person of ordinary skill in the art would have been “a person with at least a Bachelor’s degree in Electronics, Electrical, or Mechanical Engineering or related discipline, [and/]or at least three years of experience working with access control devices.” Pet. 8 (citing Ex. 1002 ¶ 19).10 Such a person of ordinary skill in the art could have both this level of education and experience without straying from Petitioner’s definition. Patent Owner neither contests Petitioner’s proposed definition of the ordinarily skilled artisan nor proposes an alternative. See generally Resp. Patent Owner’s witness, however, expressly adopts Petitioner’s definition. Ex. 2015 ¶ 20. We likewise adopt Petitioner’s proposed definition of the level of ordinary skill in the art and apply it here.11 hindsight, and is biased in favor of Petitioner because of employment history, and, hence, we should give his testimony “no weight.” See Resp. 9– 19. We do not agree with Patent Owner’s positions. The evidence shows that Mr. Comerford is qualified to testify on the issues in this proceeding, and we find his opinions are based on his understanding of the perspective of the ordinarily skilled artisan, his experience, the ordinary meaning of claim terms, and the disclosures of the prior art, are supported by evidence, and do not rely on the ’541 patent as a roadmap so as to infect his opinions with improper hindsight. See generally Ex. 1002; Ex. 1028; Ex. 1029. 10 We understand Petitioner’s proposed definition of the ordinarily skilled artisan to be inclusive regarding education and experience because such is reflected in Mr. Comerford’s cited testimony. See Ex. 1002 ¶ 19 (“I am such a person.”). 11 The parties use the acronym POSA to refer to the person of ordinary skill in the art. See generally Pet.; Resp.” slip op. at 12

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededDecided for patent owner

      “Petitioner states that “[f]or purposes of this IPR, Petitioner does not believe any claim term requires a construction in order to resolve if the Challenged Claims are unpatentable based on the prior art presented.” Pet. 21. Patent Owner indicates it agrees with Petitioner “that the terms of the Challenged Claims should be understood as written.” See Resp. 6–7. We agree with the parties and determine that no claim term requires express construction. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (holding that only claim terms that are in controversy need to be construed and “only to the extent necessary to resolve the controversy”); see also Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (applying Vivid Techs. in the context of an inter partes review). C.” slip op. at 13

    • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

      “In order to gain the benefit of the filing date of an earlier application under 35 U.S.C. § 120, each application in the chain leading back to the earlier application must comply with the written description requirement of 35 U.S.C. § 112.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1571 (Fed. Cir. 1997); see also 35 U.S.C. § 119(e)(1) (benefit of provisional application’s filing date requires disclosure of claimed invention “in the manner provided by the first paragraph of section 112”); Dynamic Drinkware, 800 F.3d at 1381–82 (“A reference patent is only entitled to claim the benefit of the filing date of its provisional application if the disclosure of the provisional application provides support for the claims in the reference patent in compliance with § 112, ¶ 1.”). “Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed. It extends only to that which is disclosed.” Lockwood, 107 F.3d at 1571–72. We agree with Petitioner that the ’773 provisional does not describe the key identification tag/device required by all claims so as to satisfy § 112. Such a component is described by the ’400 patent as the RFID tag. See Ex. 1006, Fig. 5 (element 74). The ’773 provisional, on the other hand, describes nothing that could be considered the claimed key identification tag or device “for attachment to the at least one key” as recited by claim 23 or “attaching a key identification device to a key” as recited by claim 45. Ex. 1002, 23:1–5, 24:32–35. Nothing in the ’773 provisional hints that anything, be it a tag or generic device, is attached to its otherwise disclosed key; therefore, we cannot agree with Patent Owner’s arguments. See generally Ex. 1005. The ’773 provisional merely indicates that a key can be contained in, removed from, and replaced in a key container module that can somehow sense the key’s presence, but provides no description as to how this sensing is accomplished, and certainly does not describe that anything attached to the key allows this sensing.

    • Strike new argumentNew argument disregardedDecided for patent owner

      “In our Trial Practice Guide we explain that a “[p]etitioner may not submit new evidence or argument in [a] reply that it could have presented earlier, e.g.[,] to make out a prima facie case of unpatentability.” Patent Trial and Appeal Board Consolidated Trial Practice Guide 73 (Nov. 2019)14 (“CTPG” or “Trial Practice Guide”) (citing Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1077–78 (Fed. Cir. 2015)). The Trial Practice Guide further explains that “‘[r]espond,’ in the context of 37 C.F.R. § 42.23(b), does not mean proceed in a new direction with a new approach as compared to the positions taken in a prior filing,” and “[w]hile replies and sur-replies can help crystalize issues for decision, a reply or sur-reply that raises a new issue or belatedly presents evidence may not be considered.” Id. at 74. “In most cases, the Board is capable of identifying new issues or belatedly presented evidence when weighing the evidence at the close of trial, and disregarding any new issues or belatedly presented evidence that exceeds the proper scope of reply or sur-reply.” CTPG 80 (Nov. 2019). The Board has regularly shown this capability. See Intelligent Bio-Systems, Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369–70 (Fed. Cir. 2016) (The Board refusing to consider reply brief arguments advocating a “new theory” of unpatentability under 37 C.F.R. § 42.23(b)); Apple Inc. v. e-Watch, Inc., IPR2015-00412, Paper 50, 44 (PTAB May 6, 2016) (“Accepting . . . 14 Available at www.uspto.gov/TrialPracticeGuideConsolidated. belatedly presented new arguments would be unjust to the Patent Owner and we decline to do so.”). Thus, we find any suggestion by Petitioner that Mosgrove’s entire key container or key compartment is the conductive container of Diaferia is a new and late argument, which we will not consider. Likewise, we find any suggestion by Petitioner that some sort of wire or cable (or something of that nature) might be used to connect a key put inside a conductive container to a key tag that is outside that conductive container so that the tag might be inserted into a key-sensing circuit is also a new and late argument, which we will not consider.” slip op. at 30
