      “Id. The Director neither addressed the merits of Petitioner’s challenges nor found that our prior consideration of those merits was faulty. Accordingly, we understand that we need not reconsider our conclusion that Petitioner had demonstrated a reasonable likelihood of proving that claims 1, 2, 7–9, 11, 12, and 20–24 were unpatentable or that the merits of patentability set forth in the Petition warranted institution of inter partes review.” slip op. at 5

    • BurdenDecided for petitioner

      “The question before us, therefore, is whether the Petitioner’s proffered explanation that it has proposed a different claim interpretation before the Board because the District Court may decline to adopt the narrower claim interpretations it advocates there is sufficient. We find that Petitioner’s explanation is sufficient because it follows the Director’s exemplary logic. Whether a district court has already or might in the future decline to adopt constructions that a petitioner proposes in related district court litigation merely reflects the timing of when a dispute over claim interpretation will be resolved. The Director and Patent Owner both recognize that, to resolve the dispute over claim interpretation that exists here, a decision-maker must determine “a single claim construction that best captures the true meaning of the patent claim.” Remand 4; PO Remand Br. 3. Based on the record presented by the parties to date in this proceeding, no dispute exists that the disputed claim terms mean what Patent Owner says they mean in the Litigation. Accordingly, we find that, at this stage of the proceeding, it is undisputed that Patent Owner’s interpretations of the claim terms represent the “single claim construction that best captures the true meaning of the patent claim.”8 Under that claim interpretation, we” slip op. at 8

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for patent owner

      “In Straight Path, the Federal Circuit held that the claim language “is connected to the computer network” has a facially clear meaning, that “the query transmitted to the server seeks to determine whether the second unit is connected at that time, i.e., connected at the time that the query is sent.” Straight Path, 806 F.3d at 1360.11 The Federal Circuit held that the query asks “whether the device ‘is’ connected, not whether it was connected or whether it is still registered as being connected even if that registration information is no longer accurate.” Id. The Federal Circuit further explained that “[i]t is not a reasonable interpretation of the claim language . . . to say that it is satisfied by a query that asks only for registration information, regardless of its current accuracy.” Id. The Federal Circuit explained, “[w]hen claim language has as plain a meaning on an issue as the language does here, leaving no genuine uncertainties on interpretive questions relevant to the case, it is particularly difficult to conclude that the specification reasonably supports a different meaning. The specification plays a more limited role than in the common situation where claim terms are uncertain in meaning in relevant respects.” Id. at 1361. Accordingly, the Federal Circuit construed the limitation “is connected to the computer network” as “is connected to the computer network at the time the query is transmitted to the server.” Id. at 1363.” slip op. at 11

      “and NetBIOS fail to determine whether a computer or process is connected to the computer network. PO Resp. 35, 49–51. In view of our construction of this claim limitation, we agree with Patent Owner. Microsoft Manual discloses that once a computer is registered with the WINS server (which is a NetBIOS Name Server (NBNS)) as active and on-line, the WINS server maintains a database of names and addresses as active and on-line by (1) releasing names once a computer is shut down properly and (2) requiring a renewal time period in which a computer must reregister. Ex. 1012, 62– 63, 68–69. Microsoft Manual discloses that in response to User Datagram Protocol (UDP) name queries, “a mapping in the database does not ensure that the related device is currently running.” Id. at 68. Microsoft Manual further explains that a “local WINS database should periodically be cleared of released entries and old entries that were registered at another WINS server but did not get removed from this WINS database for some reason.” Id. at 150. In other words, Microsoft Manual discloses that the WINS database may include entries of computers that are not currently connected to the WINS network. Accordingly, a query to as to whether a second process “is connected to the computer network” in Microsoft Manual will not determine whether the second process is connected to the WINS network at the time that the query is transmitted to the server. As discussed above in our claim construction analysis above (see Section I.E.1), a query as to whether a process “is connected to a computer network” or has an “on-line” status asks “whether the device ‘is’ connected, not whether it was connected or whether it is still registered as being connected even if that registration information is no longer accurate. It is not a reasonable interpretation of the claim language . . . to say that it is satisfied by a query that asks only for registration information, regardless of its current accuracy.” Straight Path, 806 F.3d at 1360. Microsoft Manual discloses that the WINS server has information that a process “was” connected to the computer network, and that information may no longer be accurate. See Ex. 1012, 68, 150. As such, we determine that Microsoft Manual does not disclose the claimed “is connected to the computer network,” “on-line status,” or “is accessible,” as construed herein. Similarly, NetBIOS discloses a registration process for resources or nodes to receive a unique name by registering a name. Ex. 1014, 379. During a name query (discovery), a datagram is sent requesting the name and address of another resource. Id. at 396. The NBNS maintains a database of resource names through explicit name deletion, where the node specifies a deletion function and implicit name deletion, which occurs when a node ceases operation. Id. at 379. NetBIOS explains that implicit name deletion “is a frequent occurrence.” Id. Implicit name deletion is managed by assigning nodes a specified lifetime for registered names, where a name is silently released if a node fails to refresh the registered name before the lifetime expires. Id. NetBIOS further discloses a mechanism where the NBNS may correct the information stored after an incorrect response is provided to a requesting node. See id. at 409. However, similar to Microsoft Manual, NetBIOS discloses that the information stored by the NBNS may be incorrect, and, therefore, will not determine whether a second process is connected to the computer network at the time that the query is transmitted to the server. Therefore, NetBIOS also does not disclose the claimed “is connected to the computer network,” “on-line status,” or “is accessible.” Given that the combination of Microsoft Manual and NetBIOS fails to teach or suggest the claims as construed, we need not reach the remaining arguments presented by Petitioner and Patent Owner.” slip op. at 19

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

      “Petitioner contends that “WINS is an implementation of NetBIOS” and, therefore, Petitioner contends that “one having skill in the art would have known about and been motivated to combine Microsoft Manual with NetBIOS.” Id. at 34 (citing 67 Ex. 1004 ¶¶ 88–89). We are persuaded by Petitioner that the combination is reasonable because Microsoft Manual demonstrates that Microsoft TCP/IP has combined the elements of NetBIOS and Microsoft Manual in the same manner in which Petitioner proposes to combine NetBIOS and Microsoft Manual. See 67 Ex. 1012, 3, 11. Microsoft Manual discloses that Microsoft TCP/IP for Windows NT provides support for application interfaces, including NetBIOS for establishing logical names and sessions on the network. Id. at 11. Microsoft Manual describes that “[w]hen WINS servers are in place on the network, NetBIOS over TCP/IP resolves names on a client computer by communication with the WINS server.” 67 Pet. 34 (quoting 67 Ex. 1012, 62). We are persuaded that Microsoft TCP/IP for Windows NT utilizes NetBIOS features for name resolution, as disclosed by Microsoft Manual, and a person with ordinary skill in the art would have readily combined the disclosures of Microsoft Manual and Microsoft Manual.” slip op. at 25

    • PTAB / AIA Trials › Real party in interest / privityRpi dispute resolved for petitionerDecided for petitioner

      “A petition for inter partes review must identify “all real parties in interest.” 35 U.S.C. § 312(a)(2). The Office Patent Trial Practice Guide provides guidance regarding factors to consider in determining whether a party is a real party in interest. 77 Fed. Reg. 48,756, 48,759–60 (Aug. 14, 2012). Considerations may include whether a non-party “funds and directs and controls” an IPR petition or proceeding. Id. at 48,760. Additional relevant factors include: the non-party’s relationship with the petitioner; the non-party’s relationship to the petition itself, including the nature or degree of involvement in the filing; and the nature of the entity filing the petition. Id. Generally, a party does not become a “real party-in-interest” merely through association with another party in an unrelated endeavor. Id. A party also is not considered a real party in interest in an inter partes review solely because it is a joint defendant with a petitioner in a patent infringement suit or is part of a joint defense group with a petitioner in the suit. Id. Whether a party who is not a named participant in a given proceeding is a “real party-in-interest” to that proceeding “is a highly fact-dependent question.” Id. at 48,759. There is no “bright line test.” Id. Courts invoke the term “real party-in-interest” to describe relationships and considerations sufficient to justify applying conventional principles of estoppel and preclusion. Id. Here, even assuming this contention is timely, Patent Owner has failed to provide any evidence, besides the mere fact that the other parties are co-defendants in a lawsuit or alleged infringers, to support the contention that Petitioner has failed to name all of the real parties in interest. That one fact, without any further proof of control or involvement by these parties in this proceeding, is insufficient to establish that Petitioner has failed to name” slip op. at 11

      “ii. Petitioner’s Expert Patent Owner asks that we “dismiss [Petitioner’s] Expert Declaration and disqualify [Petitioner’s Declarant] for making and using a false writing.” PO Resp. 9. Patent Owner contends that Petitioner’s Declarant falsely claimed that certain patent applications were patents by listing them under the heading “Patents” in his Resume. Id. at 8–9. A Patent Owner Response is not the proper vehicle to seek to exclude testimony. See 37 C.F.R. § 42.64(c). Moreover, even if it were the proper vehicle, we are not persuaded that the alleged “falsehood” that Patent Owner identified—listing patent applications, which are clearly identified as such, under a heading titled “Patents”—is, in any way, misleading. Thus, we decline Patent Owner’s request that we dismiss Dr. Vishwanath’s testimony.3 C. Motion to Amend As discussed above, in the Motion to Amend, Patent Owner requests” slip op. at 12

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “i. Level of Ordinary Skill in the Art Neither party puts forward a succinct definition of the level of ordinary skill in the art. Petitioner’s declarant, however, has put forward a detailed discussion of various references dated before April 20064 (the date Patent Owner now alleges is the priority date) related to subject matter of the ’990 patent. See Ex. 1005 ¶¶ 20–74, 94–99. We have reviewed that discussion and the references cited in those paragraphs. We have found it accurately reflects the teachings of the references. Moreover, we agree with Petitioner’s declarant that the references are analogous to the claimed invention, and, as such, represent the level of skill in the relevant art at the time of the invention. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (finding that the Board did not err in concluding that the level of ordinary skill was best determined by the references of record); In re Oelrich, 579 F.2d 86, 91(CCPA 1978) (“[T]he PTO usually must evaluate . . . the level of ordinary skill solely on the cold words of the literature.”); see 4 We accept this date as the priority date only for the sake of argument. also Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

    • ScopeMotion to amend, deniedDenied

      “We agree with Petitioner and find, based on the Patent Owner’s own arguments, that these terms improperly broaden the scope of the claims. As Patent Owner explains, the added language is broad enough to include the removed items, and is intended to reflect the entire genus of “monitoring equipment” and “communications devices” that “are capable of communication and capable of receiving signals.” Mot. to Amend 4, 5. Thus, the claim has been broadened to not only include the listed species that have been removed, but anything falling within the claimed genus. Accordingly, we find that this amendment impermissibly broadens the claim. As for the second change in the claim language, we find that Patent Owner has failed to show why removal of the entire passage “wherein, the communication device receives a signal via any of one or more products listed in any of the plurality of product grouping categories,” would not impermissibly broaden the scope of claim 154. The deletion of this limitation necessarily broadens the claim in that limitation’s aspect. See In re Clement, 131 F.3d 1464, 1468 (Fed. Cir. 1997) (“For example, a reissue claim that deletes a limitation or element from the patent claims is broader in that limitation’s aspect.”). Given that Patent Owner has entirely deleted this limitation and Patent Owner bears the burden of showing entitlement to the amendment, it was incumbent on Patent Owner to explain why removing this entire passage from claim 154 would not broaden the scope of the claim. See In re Bennett, 766 F.2d 524, 526 (Fed. Cir. 1985) (en banc) (“[A] claim is broadened if it is broader in any respect than the original claim, even though it may be narrowed in other respects.”).” slip op. at 17
