“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

“We have reviewed the relevant deposition testimony, in which Dr. Miller was asked to identify the standard he used when construing claim terms in his Declaration. Ex. 1025, 27:1–34:14. We agree with Petitioner that Dr. Miller did not provide responses sufficient to conclude that he was aware of and/or applied the correct claim-construction standard. See id. at 27:5–6 (“I used what is generally accepted in the field.”), 27:9–11 (“So to – for construing the claim terms is providing a definition of what the term is. So I provided a general definition for the terms.”), 30:3–6 (“Well, that’s the standard that I used for construing the claim terms in this Declaration. I don’t know if that’s the legal qualification for construing claim terms.”), 32:18–23 (“broadest reasonable interpretation” would mean “when you’re defining a term that you would define it in a way that is, first of all, reasonable, that it makes sense and that it’s broad, meaning general and that it’s interpreting the phrase or the term”). Nevertheless, we are not persuaded that the appropriate remedy is exclusion of Dr. Miller’s testimony. As Patent Owner asserts, “[t]he role of the expert witness under the Federal Rules of Evidence is to ‘help the trier of fact to understand the evidence or to determine a fact in issue.’” Paper 24, 2–3 (quoting Fed. R. Evid. 702) (emphasis by Patent Owner). As Patent Owner further asserts, Petitioner does not “impugn[]” Dr. Miller’s credibility as an expert in the subject matter at issue. Id. at 3–4. We agree with Patent Owner that “Petitioner’s attack on the sufficiency of the evidence is improper in a motion to exclude.” Id. at 4 (citing Microsoft Corp. v. Surfcast, Inc., Case IPR2013-00292 at 52–53 (Paper 93) (PTAB Oct. 14, 2014)). We accordingly deny Petitioner’s Motion to Exclude.” slip op. at 13

“Petitioner alternatively argues in its Reply that “Because Dr. Miller did not apply the correct claim construction standard, his opinions on claim construction (Ex. 2001, §§16-21) should be afforded no weight.” Reply 2. Although we agree that the weight to be accorded to Dr. Miller’s testimony on claim construction is impacted by the uncertainty of the analytical procedure he followed, we are not persuaded that his testimony should be discounted wholesale. Dr. Miller provides relevant opinions on a number of issues, particularly including how a person of ordinary skill in the art would understand certain terms in light of the Specification, that are helpful to us as the trier of fact. “There is no more certain test for determining when experts may be used than the common sense inquiry whether the untrained layman would be qualified to determine intelligently and to the best possible degree the particular issue without enlightenment from those having a specialized understanding of the subject involved in the dispute.” Ladd, Expert Testimony, 5 Vand.

“shared “in real time utilizing a second network protocol . . . ,” and dependent claim 59 recites that information is processed “to create, in real-time, messages in at least two other message formats . . . .” Petitioner argues that the Specification of the ’843 patent expressly defines “real-time”: “In the context of the present description, real-time may include any response time that may be measured in milli- or microseconds, and/or is less than 1 second.” Ex. 1001, col. 3, ll. 35–38. Accordingly, Petitioner proposes that “‘real-time’ should be construed as responses that occur in less than one second.” Pet. 13. Patent Owner contends that the definition from the Specification should be adopted. PO Resp. 15. We construe “real-time” as Petitioner proposes, i.e., as including responses that occur in less than one second. The first part of the quote cited above provided in the Specification (“may be measured in milli- or microseconds”) is not limiting because any response time, no matter how large or small, may be measured in milli- or microseconds.” slip op. at 16

“been reached in association with the storage request.” Petitioner proposes that “threshold” be construed consistent with a dictionary definition it provides, as a “value above which something is true or will take place and below which it is not or will not.” Pet. 13–14 (citing Ex. 1016, 5). Observing that the Specification of the ’843 patent uses “threshold” in the context of an elapsed time, Petitioner further proposes that this construction “include the maximum value (i.e., time-out) of a timer.” Id. (citing Ex. 1001, col. 8, ll. 21–25, col. 8, ll. 47–51). We agree, and accordingly construe “threshold” as Petitioner proposes.3 3. “heterogeneous networks” Dependent claim 55 recites that the “apparatus is operable such that the first network and the second network are heterogeneous networks.” The Specification of the ’843 patent defines “heterogeneous networks”: “In the context of the present description, heterogeneous networks may refer to any different communication networks with at least one aspect that is different.” Ex. 1001, col. 7, ll. 26–29. In light of this explicit definition, for purposes of this Decision, we construe “heterogeneous networks” as Petitioner proposes, i.e., as “networks having at least one aspect that is different.” Pet. 14 (citing 3 Patent Owner advocates for the same construction advanced by Petitioner, but omits inclusion of the maximum value of a timer. PO Resp. 15. Although Patent Owner asserts that the construction is otherwise “the definition provided by the ‘843 Patent,” it does not cite to the ’843 patent to support its assertion, and we are unable to identify such a definition in the patent. Nevertheless, we agree with Petitioner that any distinction between the constructions is not material to any grounds. See Reply 6.” slip op. at 16
