“whether the motion to amend meets the statutory and regulatory requirements set forth in 35 U.S.C. § 316(d) and 37 C.F.R. § 42.121.” See Lectrosonics, Inc. v. Zaxcom, Inc., IPR2018-01129, Paper 15 at 4 (PTAB Feb. 25, 2019) (precedential). A “patent owner bears the burden of persuasion to show, by a preponderance of the evidence, that the motion to amend complies” with the applicable statutory and regulatory requirements. 37 C.F.R. § 42.121(d)(1). Specifically, a patent owner must demonstrate the following: (1) the amendment proposes a reasonable number of substitute claims; (2) the amendment responds to a ground of unpatentability involved in the trial; (3) the amendment does not seek to enlarge the scope of the claims of the patent; and (4) the amendment does not introduce new matter. See 35 U.S.C. § 316(d); 37 C.F.R. § 42.121(a)–(b). For the reasons explained below, Patent Owner satisfies its burden of persuasion to show that the amendments comply with the applicable statutory and regulatory requirements.” slip op. at 8

“Both parties rely on expert testimony for their respective positions relating to the number of years of experience needed to attain ordinary skill, but neither expert cites supporting evidence for their testimony. See Ex. 1002 ¶ 33; Ex. 2002 ¶ 15. Our decision is the same regardless of whether the length of experience is two years or three. We find Patent Owner’s proposed “wireless communications” is more consistent with the ’958 patent than Petitioner’s proposed “telecommunication,” which encompasses a variety of technologies including, e.g., landline and wireless telephones, cable, and satellite. See Ex. 1001, 1:11–62 (describing the invention in terms of wireless communications). Accordingly, we adopt a modified version of Petitioner’s proffered level of ordinary skill in the art, substituting “wireless communications” for “telecommunication.” Neither party, moreover, indicates the overall result would change based on a different definition.” slip op. at 18

“We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13. For the above reasons, we do not agree with Petitioner that the recited second type SIB lacks any requirements, nor do we interpret claims 7 and 8 such that the first type SIB could be a second type SIB.” slip op. at 19

“(d) Limitation 7h: Analysis We agree with Patent Owner that Petitioner’s arguments with respect to limitation 7h are insufficient because they fail to address the limitation as written and improperly incorporate previous arguments by reference. For example, Petitioner did not map the recited “group identifier” when opposing Patent Owner’s Revised Motion to Amend. See Opp. 16–17. In its Sur-reply, Petitioner contends that limitation 7h’s requirement of transmitting the group identifier was previously “set out in Patent Owner’s prior papers,” but does not refer to any specific papers or exhibits. Pet. Surreply 11–12. We decline to search for and piece together Petitioner’s arguments and evidence to develop a persuasive theory of unpatentability. See 37 C.F.R. section 42.6(a)(3). Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet. Sur-reply 12. This conclusory statement is not supported by any citations to evidence and was improperly introduced in the Sur-reply. Moreover, whether it was obvious to determine what system information is broadcast is not commensurate with the claim scope because limitation 7h requires that the broadcasting (not the broadcast content) be based on a comparison of the value tag. See supra III.B.4 and IV.B. Further, we are not persuaded that Lee’s transmitting by broadcast is” slip op. at 26

In denying the Petition, the Prior Decision noted that “Petitioner has taken no steps to explain or respond to the effect of these developments on its argument.” Dec. 7. This remains true. Nevertheless, we agree with Petitioner that our Prior Decision gave insufficient consideration to the Petition’s assertion that “U.S. Patent No. 7,613,926 [(“the ’926 patent”), i.e., an intermediate patent in the priority chain of the ’086 patent] fails to claim priority to the ’639 provisional application and instead the earliest priority document cited in the ’926 patent is [the ’194 patent].” Pet. 5 (citing Ex. 1012, col. 1, ll. 8–32); see Req.

“a formally defined safety policy” and allows checking “with certainty, that the proof is valid and hence the foreign code is safe to execute.” Ex. 1004, 107. Thus, Petitioner argues that one of ordinary skill in the art would reasonably understand Necula to teach that its proof-carrying code adds to the foreign code, consistent with the construction of “append” that we apply herein, and Petitioner articulates sufficient reasoning with rational underpinning to apply that teaching to Swimmer’s representation of DSP data. See Pet. 46–49. This is not an instance, for example, in which Petitioner relies on a characterization of the problem provided by the patent to derive its reasoning. Cf., e.g., Mintz v. Dietz & Watson, Inc., 679 F.3d 1372 (Fed. Cir. 2012). Indeed, Patent Owner’s contention that “the storage of the DSP in a database is one of the key features that distinguishes the ‘086 Patent over the prior art” dilutes the strength of its argument. The contrary positions of the parties’ declarants in their testimonial evidence creates a genuine issue of material fact, which we resolve in the light most favorable to Petitioner for purposes of this Decision. 37 C.F.R. § 42.108(c). Accordingly, we conclude that Petitioner has made a sufficient showing also with respect to these elements, and that Petitioner demonstrates a reasonable likelihood of prevailing on its challenge of claims 1 and 9.

Petitioner’s proposed construction parallels a statement made in the Specification of the ’194 patent. Ex. 1012, col. 1, ll. 44–47. Patent Owner “does not dispute” this proposed construction, which we adopt for purposes of this Decision. Prelim. Resp. 5. 2. “database” Challenged independent claim 42 recites “a database of Downloadable security profiles.” Petitioner contends that “[t]he broadest reasonable interpretation of the term ‘database’ includes ‘a collection of interrelated data organized according to a database schema to serve one or more applications.’” Pet. 15. Patent Owner also “does not dispute” this proposed construction, but argues that “the practical import of Petitioner’s proposed construction for the term ‘database,’ is that log files, such as Swimmer’s audit trail, do not fall within the scope of the claims.” Prelim.

“i. Jaffray MICCAI 2001 Teaches “a translatable treatment couch coupled to the rotatable gantry via a communications network” Claim 6 requires “a translatable treatment couch coupled to the rotatable gantry via a communications network.” As Petitioner explains, the linear accelerator in Jaffray MICCAI 2001 is an Elekta SL-20.

A technical note describing the SL-20 explains as follows: “The hardware/software interaction of the SL-20 makes it particularly suitable for automated data collection. Communication between the control processor and the accelerator, gantry and patient couch is handled by a pair of high-speed serial links. These are daisy-chained through three separate control areas distributed throughout the machine.” Ex. 1015, 220. “[R]ecourse to extrinsic evidence is proper to determine whether a feature, while not explicitly discussed, is necessarily present in a reference.” Telemac Cellular Corp. v.

“We agree with Patent Owner that using a computer-controlled treatment couch does not necessarily mean the treatment couch is connected to the gantry via a communications network, as claim 6 requires. See PO Resp. 28. As Patent Owner explains, controlling the couch with a computer “says nothing about how, if at all, the table would be coupled to the rotatable gantry.” Id. In addition, Petitioner’s standard-feature argument, even if correct, is not enough to show the Jaffray Publication necessarily discloses the disputed communications network feature. See Rexnord Indus., LLC v. Kappos, 705 F.3d 1347, 1355 (Fed. Cir. 2013) (explaining that “anticipation by inherent disclosure is appropriate only when the reference discloses prior art that must necessarily include the unstated limitation”). Thus, we find Petitioner has not shown the Jaffray Publication expressly or inherently discloses “a translatable treatment couch coupled to the rotatable gantry via a communications network,” as claim 6 requires, and consequently has not met its burden to show the Jaffray Publication anticipates claim 6. 4.

“We are not persuaded by this reasoning. As Petitioner observes, the embodiments of the ’624 patent identified by Patent Owner are characterized as “examples,” and a person of ordinary skill “would understand that the example scenarios of the specification are not necessarily limiting on the claims.” Reply 3 (citing Ding Supp. Decl. ¶ 6). In addition, Petitioner notes that claim language in related patents owned by Patent Owner explicitly refers to participants, evidencing Patent Owner’s understanding “how to expressly create participant-specific voting requirements in claims.” Id. at 3. At the oral hearing, Patent Owner suggested that explicit reference to participants in such other claim language “was because it wanted to clarify that each participant got a single vote,” and explained its position that, in the claims at issue in this proceeding, “participant is implicit in the claim language as it is.” Tr. 78:16–25. But the claims are directed to a “communications apparatus,” and recite “votes” in the context of what the “particular communications channel” “receives.” Nothing within the structure of the claims requires resolving the origin of such votes. Furthermore, Patent Owner’s proposed construction is inconsistent with the construction it agreed to before the district court in the Qualcomm Litigation. In that litigation, the parties agreed that the term “vote” should be construed as “a binary expression (to use or not to use),” a construction that makes no reference to the origin of the “vote” as from a participant or otherwise. Ex. 1014, 6. We see no compelling reason to excuse the inconsistency by adopting a narrower construction when the Board applies a claim-construction standard (broadest reasonable interpretation) that could only result in the same or a broader construction. See Amazon.com, Inc. v. Barnesandnoble.com, Inc., 239 F.3d 1343, 1351 (Fed.

“Patent Owner responds that “the Gerten device is not capable of and expressly teaches away from performing this functionality.” PO Resp. 15 (citing Melendez Decl. ¶ 33). Patent Owner contends that “Gerten’s disclosure is directed toward eliminating channels for use in an entire piconet as opposed to eliminating channels for use by certain participants within a piconet.” Id. at 16 (emphasis added). Patent Owner argues that Gerten does not disclose a selection kernel capable of maintaining synchronization between a master and more than one slave in a piconet, with the master and one slave using a default set of channels while the same master and a different slave use a different set of channels. Id. We are not persuaded that the absence of a specific teaching of such a selection kernel supports the conclusion that one of skill in the art would understand Gerten to function in the manner Patent Owner suggests. In this instance, Petitioner refers to two embodiments of Gerten “in which a first participant communicates with a second participant via a normal sequence and with another participant via an adaptive hopping sequence.” Reply 5. First, Figure 3 of Gerten is reproduced below. Figure 3 illustrates “methodology for determining and communicating channels to be avoided to a remote device.” Ex. 1003, col. 2, ll. 4–6. As illustrated in the drawing, a master unit performs a discovery process (block 110) upon connecting with a new slave unit. Ding Decl. ¶¶ 60, 64. If the slave unit is capable of using interference avoidance, the master unit begins the process of determining a modified set of channels for use (block 120). Id. ¶ 45. If a second slave unable to use interference avoidance enters the piconet, standard frequency hopping is used. Supp. Ding Decl. ¶ 9. Under Patent Owner’s characterization of Gerten, entry of the second slave into the network would require the first slave necessarily to revert back to the default hopping sequence. Id. ¶ 10. But this would undermine the stated benefits of Gerten, which explicitly discloses: The above process can be applied to a Bluetooth example and includes identification of a Bluetooth device’s ability to support interference avoidance, the measurements of signal strength on all channels and identification of which channel should not be used without violating the FCC rules, a method of modifying the Bluetooth hop sequence so that it will avoid channels containing strong or fixed interferers while still supporting standard Bluetooth hopping with other non-enabled members of the piconet and a method of relating necessary interference avoidance information to the remote Bluetooth devices.
