  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Patent Owner asserts that a person of ordinary skill in the art at the time of filing “would have had a Bachelor’s degree in electrical engineering, computer science, or the like, and/or four or more years of experience in server-based applications” and that “[a]dditional experience may make up for a lack of education and vice versa.” PO Resp. 9. Because Petitioner’s proposed level of ordinary skill in the art appears to be consistent with the challenged patent and prior art, we adopt it and use “skilled artisans” to refer to people with such skill at the time the invention was filed. We do not perceive a substantive distinction between the parties’ definitions, but note that Petitioner’s definition provides more detail about the capabilities of skilled artisans. Also, the level of ordinary skill in the art can be evidenced by the references cited, and we find it commensurate with the cited references in this proceeding. See Okajima v.

    “device indicated by the session data” encompasses “determining a notification method based on” session data indicating the current state of the external device, where the current state of the device encompasses an online state as well as an offline state. See Pet. 53–54; Tr. 55:3–10 (The Board: “Are there any other states of an external device other than online or offline?” Patent Owner: “As far as I know, Your Honor, those are the only two[.]”), Tr. 65:24–66:1 (The Board: “When the claim says current state, they mean it’s online or offline?” Petitioner: “Correct.”), Tr. 20:23–21:8. The specification is consistent with the plain language of the claim in disclosing two examples of the claimed “current state,” namely, online and offline. Ex. 1101, 21:1–4. The specification discloses that the notification manager “queries session manager 456 to determine the user’s connectedness.” Id. at 21:6–8. The specification discloses that if the user is “online, notify by, for example, the user’s active session. If offline, notify by, for example, a txt [sic] message, call the user’s landline, call a friend of the user, and the like.” Id. at 21:1–4, 23:28–31.” slip op. at 13

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

    “Patent Owner’s expert witness, Dr. Goodrich, show written description support for providing a notification to an active external device, Patent Owner has not cited any portion of the 2009 Parent, nor any portion of the testimony of Dr. Goodrich, to show that the 2009 Parent provides written description support for determining a notification method by which to provide an alert to an external device based on the current state of the external device as offline. We highlight that Paragraphs 130 and 131 of the 2011 CIP Application disclose offline notification preferences for determining a notification method by which to provide an alert to an external device based on the current state of the external device as offline. Ex. 1110 ¶¶ 130–131. Specifically, paragraphs 130 and 131 describe that: the notification manager of the eventing and alerting subsystem 452 queries the configuration server 454 for the user's notification preferences and correlates these notification preferences with session manager 456 to determine the best notification method. That is, the notification manager queries the configuration server 454 and determines, for example, that the user has certain online notification preferences and certain offline notification preferences. If online, notify by, for example, the user's active session. If offline, notify by, for example, a txt message. . . . The notification manager of the eventing and alerting subsystem 452 then queries session manager 456 to determine the user's connectedness. Id. That is, if the user’s connectedness, or “current state” of the claimed external device, is offline, and the user’s offline notification preferences are “notify by txt message,” the notification manager will determine that the notification method for the external device having a current state of offline is by txt message. See id. Thus, the 2011 CIP Application describes a notification manager that queries a session manager to determine whether an external device is offline, and if the external device is offline, determines a notification method for providing an alert on the external device based on the current status of the external device as offline and the user’s offline notification preferences. Although we find this written description support for the determining limitation in the 2011 CIP Application, we do not find this written description support in the 2009 Parent.” slip op. at 25

    “As to the “determining a notification method” limitation (1.10), Petitioner asserts that Austin-Lane teaches determining: (1) the user device(s) to send the notification to (e.g., phone, PDA, notebook computer, desktop computer); (2) the communication protocol to use to send the notification, i.e., how to send the notification (e.g., SMTP (for email), SMS (for texts), HTTP (for web browsers)); and (3) the type of alert to provide, i.e., how to present the notification, (e.g., text, an icon, a pop-up window, a video, an email, an audible or tactile alarm), based on the current state of the at least one external device indicated by the session data (“presence information”), which may include whether and on which device(s) the user is online and/or whether and on which applications the user has an active session. Id. at 53 (internal citations omitted) (citing Ex. 1105 ¶¶ 4, 5, 29, 32, 33, 39, 46, 48, 61, 79, Fig. 1). We highlight that paragraph 61 of Austin-Lane discloses that: The type preferences 650 may include preferences for various notification types. . . . [A]uction alert #1 660 defines the following delivery precedence 663: (1) a web browser (if the user is online), (2) an IM client (if the user is online), (3) a mobile phone #1, (4) a PDA, (5) a mobile phone #2, (6) a pager, and (7) an email inbox. Ex. 1105 ¶ 61; see id. ¶¶ 74–77 (Describing that one of several notification methods for delivering an alert to a user’s device is determined based on the current state of the user’s device as online or offline).

Patent Owner does not argue that we should exercise discretion under 35 U.S.C. § 314(a) because Petitioner uses more than one petition to challenge the ’731 patent. challenges the alleged priority date of the ’731 patent (IPR2024-01489) (‘First Petition’) and the second petition assumes that the Patent Owner’s claimed priority date is valid, and addresses prior art references predating that priority date (IPR2024-01490) (‘Second Petition’).” Ex. 1019, 1. In accordance with the Consolidated Trial Practice Guide1 (“CTPG”), issued in November 2019, “there may be circumstances in which more than one petition may be necessary” including “when there is a dispute about priority date requiring arguments under multiple prior art references.” CTPG 59.

    “We do not agree. Petitioner notes that certain disclosures added to the April 2011 CIP application describe a “notification manager” to “determine the best alert notification method.” Pet. 27 (quoting Ex. 1110 ¶ 131; citing id. ¶¶ 90–93, 130–132, 145–147, 160). That does not mean that Petitioner construes the claim language to require determining the best method, only that disclosing a mechanism that “determine[s] the best alert notification method” provides written-description support for a requirement to “determin[e] a notification method.” Petitioner is clear in its position that the May 2009 application “does not describe how to determine a notification method or how to use ‘session data’ in the manner required by this claim limitation.” Pet. 27–28. Patent Owner asserts that the May 2009 application discloses “determining a notification method” through a channel alert server that can “determine the active devices of the subscriber . . . to provide a visual or auditory alert in the channel.” Prelim. Resp. 32 (quoting Ex. 1106 ¶ 39). That disclosure appears to address the claim language requiring an alert “based on the current state of the at least one external device indicated by the session data.” It does not, however, address the claim language “determining a notification method.” Patent Owner recognizes that Petitioner asserts disclosures in the prior art for “determining which devices to send the alert to, the protocols used to send the alert, and how alerts are presented.” Id. at 34 (emphasis omitted). But when Patent Owner asserts that the May 2009 application discloses determining how alerts are presented, it points to paragraphs that do not support the assertion. Id. at 35 (citing Ex. 1106 ¶¶ 23, 39). The first, paragraph 23, states that a “trigger may cause the information channel to change its appearance or to take other actions that may be implemented by the developer” and that “one action that may be implemented is to provide a notification to the user.” Ex. 1106 ¶ 23. Nothing about that indicates the system determines how an alert is presented. The second, paragraph 39, states that the channel alert server may “provide a visual or auditory alert in the channel” and that the “alert can appear as defined on other platforms.” Nothing about that indicates the system determines how an alert is presented. Patent Owner has not shown how the May 2009 application discloses a determining a notification method, as claimed. In Patent Owner’s view, Petitioner admits that the May 2009 application (which is the same as the asserted PCT publication) describes determining a delivery mechanism because Petitioner compares it to Austin-Lane, stating that the PCT publication “already includes a channel alert server that determines the active devices of the user and delivers an alert to the user’s device” and “discloses setting the same type of alert (stock alert) and presenting it in the same way (visually) as Austin-Lane.” Prelim. Resp. 35 (quoting Pet. 54) (emphasis omitted). But simply delivering an alert does not necessarily mean the notification method for that alert was determined. We conclude that Petitioner’s statement does not show the PCT publication discloses “determining a notification method” as claimed.” slip op. at 20

  • 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.

    “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. Thus, we find that the ’011 provisional application does not “clearly allow persons of ordinary skill in the art to recognize that [the inventors] invented what is claimed.” In re Gosteli, 872 F.2d 1008, 1012 (Fed. Cir. 1989); Lockwood v. American Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 8 Patent Owner contends that the statement in the ’253 patent regarding the “exemplary embodiment” of “forward flow” is referring to an embodiment in which the volume of the liquid drawn out from the lumen of the catheter is “approximately 0.2 ml.” PO Resp. 40–41 (citing Ex. 1001, 32:35–36; Ex. 1003 ¶ 126; Ex. 2014 ¶ 99).

    “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.

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. The parties also do not indicate that the outcome would differ based on the definition of the person of ordinary skill in the art. See Pet. 15; PO Resp. 6; Pet. Reply 1.” slip op. at 10

  • 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 ’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. 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.”” slip op. at 14

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

    “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 Ex. 1030 ¶ 29; 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).” slip op. at 21

  • Novelty / Anticipation (§102) › Prior-art status of a reference › Patents / published applications (effective date, provisional support)Reference is prior artDecided for petitioner

    “AIA § 102 draws a distinction between actually being entitled to a right of priority to, or the benefit of, a prior-filed application according to the definition of “effective filing date” of a claimed invention in AIA 35 U.S.C. § 100(i)(1)(B), and merely being entitled to claim a right of priority to, or the benefit of, a prior-filed application for prior-art purposes according to the use of “effectively filed” in AIA 35 U.S.C. § 102(d). 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. For example, a 2018 Memorandum to the Patent Examining Corps states, in the context of prior-art determinations, that “[t]he requirement that one of the claims in the patent [document] . . . be supported by the written description of the provisional application in compliance with pre-AIA 35 U.S.C. § 112, first paragraph (or AIA 35 U.S.C. § 112(a)), is not applicable when examining an application subject to the first inventor to file provisions of the AIA.” Robert W. Bahr, Memorandum re: Critical Reference Date Under pre-AIA 35 U.S.C. §102(e) (Apr. 5, 2018), available at http://www.uspto.gov/sites/ default/files/documents/dynamic_memo_05apr2018_0.pdf (emphasis added) (citing Dynamic Drinkware, 800 F.3d at 1381 n.2; 157 Cong. Rec. 3423 (2011) (explaining the distinction between being entitled to claim priority or benefit in AIA 35 U.S.C. § 102(d) and actually being entitled to priority or benefit under 35 U.S.C. § 119, 120, or 365)). This Memorandum further indicates: The date subject matter was “effectively filed” under AIA 35 U.S.C. § 102(d) for purposes of considering a U.S. patent, a U.S. patent application publication, or an international application publication as prior art under AIA 35 U.S.C. § 102(a)(2) is discussed in MPEP § 2154.01(b), and is not affected by Dynamic Drinkware or [Amgen v. Sanofi, 872 F.3d 1367, 1380 (Fed. Cir. 2017)] and is not being modified by this memorandum. Id. at 2. MPEP § 2154.01(b) explicitly states, as a result of the distinction discussed above, in application of the AIA version of § 102, “the question of whether a patent or published application is actually entitled to priority or benefit with respect to any of its claims is not at issue in determining the date the patent or published application was ‘effectively filed’ for prior art purposes.” MPEP § 2154.01(b) (emphases added).” slip op. at 31
