RulingsFinal written decision- 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. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).” slip op. at 9
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner
“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). Thus, Austin-Lane describes determining a notification method by which to provide an alert on an external device based on the current state of the external device as online as well as offline.” slip op. at 29

PO Resp. 7–10. Patent Owner also points to dependent claims 6–9 as relying on the preamble reciting “a deodorant stick” as antecedent basis for claim elements. Id. at 9. We agree. Petitioner does not provide argument to the contrary. See, e.g., Pet. 19 (arguing that Lesniak discloses a deodorant stick in the form of an antiperspirant stick).

The disclosures of KR ’754 cited by Patent Owner to show written description support show: (1) multiplexed terminals over respective channels, (see Ex. 1008 ¶¶ 65–66, Fig. 10); (2) differing the number of AID values in the batch acknowledgment (BA) information field when the number of terminals assigned to each channel differs, setting the length of each multiplexed group ACK differently, and, if necessary, aligning the lengths of the multiplexed group ACKs based on the channel with the longest assigned BA information by adding zero padding or repeatedly inserting BA information (see Ex. 1008 ¶¶ 66–70, Fig. 11); and (3) applying the use of the AID field padding and the use of BA padding in a downlink OFDMA trigger process during multi-user downlink transmission to align the length of the trigger when the AP notifies the terminals assigned to each channel by inserting zero padding or repeating AIDs (see Ex. 1008 ¶¶ 71–72, Figs. 11–12). KR ’754 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a trigger frame indicating uplink transmission for one or more terminals that includes an AID field used to identify whether the trigger frame includes a padding field, and the trigger frame including the padding field when the AID field is set to a specific value. In particular, we do not discern disclosure in KR ’754 that conveys that the inventor possessed the following: (1) a trigger frame indicating uplink transmission to one or more terminals and including an AID field used to identify whether the trigger frame includes a padding field; (2) the AID field for the trigger frame is set to a specific value, and (3) that trigger frame includes the padding field when the AID field is set to a specific value. We find misplaced Patent Owner’s argument that “KR ’754’s discussion about Figure 10 and Figure 11 would have been understood [by a POSITA] as disclosing a padding method used to improve predictability and consistency trigger frame” (Prelim. Resp. 12) because: (1) it addresses uplink transmissions and not a trigger frame indicating uplink transmission to one or more terminals; (2) it does not address that the padding field is included in the trigger frame when the AID field is set to a specific value; and (3) it is unsupported attorney argument regarding the understanding of a person of ordinary skill in the art. Argument of counsel cannot take the place of objective evidence. See Gemtron Corp. v. Saint-Gobain Corp., 572 F.3d 1371, 1380 (Fed. Cir. 2009). We also find misplaced Patent Owner’s argument that “the padding discussed by KR ’754 regarding its Figure 12 embodiment is not limited to downlink transmission and would have been understood by a POSITA as also being used to schedule uplink ones” (Prelim Resp. 14) because: (1) KR ’754 does not provide any suggestion that the same technique can be used for uplink transmission trigger frames; (2) Patent Owner’s argument does not address that the padding field is included in the trigger frame when the AID field is set to a specific value; and (3) Patent Owner’s argument is unsupported attorney argument regarding the understanding of a person of ordinary skill in the art. See Gemtron, 572 F.3d at 1380. For the foregoing reasons and based on this record, for the purpose of institution, we find that the ’186 Patent is not entitled to an effective filing date earlier than April 8, 2019 and find that Kim is prior art. We note that the limitations at the heart of the written description dispute were added in an amendment filed August 9, 2020. See Ex. 1002, 214–21.

“We do not agree with Patent Owner’s arguments because they are premised on Choi’s teachings as limited to AIDs transmitted via a control frame broadcast as a TIM element.

“We note that the identification of a Ph.D. as an example of “more formal education” creates a vast range of education relative to a bachelor’s degree. Thus, we treat the identification of a Ph.D. just as it is—an example—and not a requirement. In this case, “more formal education” can be satisfied by a level of education less than a Ph.D (but greater than a bachelor’s degree). Based on our review of the record before us, we determine that Petitioner’s stated level of ordinary skill in the art is reasonable because it appears consistent with the evidence of record, including the asserted prior art.

“Petitioner argues that one of ordinary skill in the art would have found the proposed modification obvious for several reasons. Pet. 30. For instance, Petitioner argues that “Unger contains an express teaching, suggestion and/or motivation to incorporate an element such as Smith’s torsional spring into the lower and/or upper mount assemblies 308, 312 to facilitate attachment and detachment.” Id. Namely, Petitioner points to Unger’s disclosure that device mounts 308, 312 may be flexible or resilient so that device mounts 308, 312 may be bent to engage a portion of hearing protection device 108 and are then allowed to return to a normal state to secure communication device 104 to hearing protection device 108. Id. at 30–31 (quoting Ex. 1004, 6:20–37). Petitioner adds that one of ordinary skill in the art would have understood this disclosure “to teach that mount arms 308, 312 could be removable from housing 304 (e.g., as mount arm 312 is in Figure 6) and/or they could be designed to be ‘flexible’ or ‘resilient’ such that they can be manipulated,” and “that ‘resilient’ is defined as ‘bouncing or springing back into shape, position, etc. after being stretched, bent, or, esp., compressed.’” Id. at 31 (citing Ex. 1002 ¶ 117). Thus, according to Petitioner, this disclosure of Unger suggests using a torsion spring. Id. In addition, Petitioner asserts that one of ordinary skill in the art would have understood Unger’s disclosure to “suggest the use of a torsion designed to impart this functionality.” Pet. 30 (citing Ex. 1002 ¶ 118). Petitioner also asserts that one of ordinary skill in the art would have “understood that there were a limited number of ways to impart the referenced resilient or flexible ‘manipulation,’” and “would have been motivated to look to various known solutions to impart the suggested functionality, including the torsional spring mechanism of Smith that is used in a similar hearing protection device application for a similar purpose as Unger’s mounting arms (to apply a clamping force).” Id. at 32 (citing Ex. 1002 ¶¶ 120–121). Other reasons for combining the references set forth by Petitioner are the proposed modification: (1) “would have involved applying a known technique to a known device ready for improvement to yield predictable results” (Pet. 39–49 (citing Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380 (Fed.

“distinct from “comminute[ion],” Petitioner offers only the testimony of its expert, Mr. Juzkow, who equates Tomioka’s “cutting” with “comminute[ion].” See Ex. 1003 ¶ 121. However, Mr. Juzkow provides insufficient reasoning to support his conclusion, particularly given the intrinsic and extrinsic evidence discussed above. In contrast, Patent Owner’s expert, Mr. Dantam, provides extensive reasoning, supported by citations to other evidence, to support his conclusion that Tomioka’s “dismantling” is not the claimed “comminution.” Thus, we give more weight to Mr. Dantam’s testimony than Mr. Juzkow’s testimony.

“obvious. Pet. 34–35. However, we agree with Patent Owner that Petitioner has also failed to show that it is more likely than not that Tomioka renders this limitation obvious. See Prelim. Resp. 28–31. To begin with, Petitioner’s contentions lack sufficient reasoning explaining why a person of ordinary skill would have modified Tomioka in the manner proposed. “[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). Petitioner merely asserts that a person of ordinary skill in the art could use the roller system in place of the dismantling disclosed for the embodiments in Figures 19 and 20. On this record, we find this bare contention insufficient. actual disclosure of Tomioka. The rollers in Tomioka are used to separate the “battery body” from the “resin package enclosing the battery body,” and Tomioka specifically discloses that this technique is designed to “avoid damaging the battery body.” Ex. 1005 ¶¶ 25, 26, 29; Ex. 2011 ¶¶ 72–73. Thus, there is a significant difference between what Tomioka teaches and what Petitioner proposes to use the roller system to do. In addition, as Patent Owner points out, Tomioka specifically discloses there are risks associated with mechanically crushing battery packs, such as “risk of sparking due to residual voltage if the battery units are damaged in the process.” Ex. 1005 ¶ 5. Although we do not agree with Patent Owner that this amounts to a “teaching away,” see In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994), we do believe that this teaching suggests a trade off that should be weighed in determining whether to make the modification, see Medichem S.A. v. Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). However, Petitioner has failed to account adequately, if at all, for this trade off.

“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

“a contact surface of said thermo-roller is heated to an elevated temperature of at least 250°F.” Petitioner shows persuasively that the temperature limitation is taught by the combination of Fugitt and Papermaking. Pet. 32–34. Fugitt discloses that “[t]he rolls of the calender may be steam heated.” Ex. 1004 ¶ 26. In a section titled “Heated Rolls,” Papermaking discloses that “Steam can be used up to 170°C [338°F] surface temperature.” Ex. 1010, 95, 98.

Based on these disclosures, we are persuaded by Mr. Zotterman’s testimony that it would have been “obvious to heat the thermo-roller of Fugitt to at least 250°F.” Ex. 1003 ¶ 159. combine Fugitt and Papermaking because of Papermaking’s status as a “trusted handbook[],” because both references disclose a method of manufacturing a paperboard structure with hot calendering,” and “because of the known advantages of heated rollers.” Pet. 36–37; Ex. 1003 ¶¶ 157, 159, 162. Petitioner’s contention is supported by Papermaking’s disclosures that, for cartonboard, “[p]recalendering is used before the coater to reduce roughness and porosity” and “[h]igh thermo roll temperatures (in some cases over 200°C) result in bulk savings because of the temperature gradient.” Ex. 1005, 80–82; see also Pet. 38; Ex. 1003 ¶ 164 (citing these disclosures). Papermaking’s disclosed range of “up to 170°C [338°F]” for steam- heated rolls (Ex. 1010, 98), overlaps the claimed range of “at least 250°F.” Patent Owner agrees.

Resp. 13 (noting that Petitioner does not identify other limitations in the challenged claims “allegedly lacking support in the ’202 patent family’s applications dating back to U.S. App. No. 11/550,634, filed on October 18, 2006”). Accordingly, we determine that Petitioner does not demonstrate that it is more likely than not that the challenged claims lack written support in the Specification (and the ’634 application). That is, on this record, it appears that the challenged claims properly claim priority to the ’634 application and, accordingly, have an effective filing date in October 2006.” slip op. at 17

Claim 16 is unpatentable as obvious over Ellsberry; the Board did not reach the Perego-422 or Perego-422 and Amidi grounds.

“On this record, we accept Petitioner’s statement of the level of ordinary skill in the art except that we omit the qualifiers “at least” before years of education and experience because they render the level ambiguous and may encompass levels that are beyond ordinary. Otherwise, we find Petitioner’s statement of the level of ordinary skill in the art consistent with the ’912 patent and the applied prior art references. Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (the applied prior art may reflect an appropriate level of skill).” slip op. at 12

“However, the subsequent emphasized sentences (id. at 8:54–60) could only be understood in favor of Petitioner’s interpretation. If “the command signal is passed through to both associated ranks” and “the command signal is sent to both memory devices,” each rank must have only one memory device. Thus, we agree with Petitioner that this passage means that a rank may have only one memory device. Patent Owner argues that this paragraph of the ’912 patent (id. at 8:44–64) must be read in conjunction with its Figures which show multiple memory devices per rank. PO Resp. 7 (citing Ex. 1001, 6:31–38, 20:64–65, 22:34–35, Figs. 1A, 1B, 2A, 3A; Ex. 2062 ¶¶ 106–107). However, the disputed paragraph refers to “certain embodiments” which do not necessarily correspond exactly to what the Figures depict, and the Figures are described as “exemplary” and “compatible with” or “in accordance with certain embodiments described herein.” See, e.g., Ex. 1001, 3:32–48. We find no statement here or elsewhere in the ’912 patent that a rank must include multiple memory devices, and cannot include a single memory device.” slip op. at 18

“We agree with Petitioner that the ’244 provisional does not provide written description support under § 112 ¶ 1 for claim 16 of the ’912 patent. There is no mention of “bank address” signals in the ’244 provisional. In order to find that “bank address” signals are present, according to Patent Owner’s arguments and the evidence presented, one would have to (1) assume at least that the ’244 provisional pertains to DDR memory modules (when there is no mention of DDR and there were other types of DRAM devices on the market) because Figure 1 suggests them by its use of chip select signals and the term “rank,” and because they were the most common at the time; (2) understand that DDR DRAMs use bank address signals according to the JEDEC standards; (3) recognize that bank address signals are not mentioned in the ’244 provisional; (4) infer that bank address signals would be included as part of the control signals (even though the other address signals are explicitly mentioned and set out separately); and (5) infer that the bank address signals are used for rank multiplication (when row/ and column/address could have been used for this purpose). This is a chain of inferences too long and speculative to show that the ’244 provisional demonstrates that the inventors had possession of the subject matter of claim 16.” slip op. at 29

“We agree with Petitioner on this issue, which is currently on appeal before the Court of Appeals for the Federal Circuit. Lynk Labs, Inc. v. Samsung Electronics Co., Ltd., Appeal No. 23-2346, Doc. 14, page 15 (Fed. Cir. Jan. 10, 2024). In an inter partes review, a petitioner “may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed publications.” 35 U.S.C. § 311(b). Ellsberry is a printed publication, having been published in December 2006, as Patent Owner acknowledges. See Ex. 1037, code (43) (publication date of Dec. 7, 2006); see also PO Resp. 54 (acknowledging publication in December 2006). Ellsberry is prior art at least under 35 U.S.C. § 102(e)(1), being “an application for patent, published under section 122(b), by another filed in the United States before the invention by the applicant for patent.” See Ex. 1037, code (22) (filing date of June 1, 2005). Thus, Petitioner asserts a permissible ground of unpatentability under 35 U.S.C. § 311(b) because it argues that claim 16 is unpatentable under 35 U.S.C. § 103(a) on the basis of prior art (Ellsberry), which is a printed publication. Accordingly, we determine that Ellsberry is prior art to the ’912 patent at least under pre-AIA 35 U.S.C. § 102(e)(1).” slip op. at 35
