“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
- Skill levelSkill level patent owner adoptedDecided for patent owner
“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
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner
“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

“Although a claim term that does not include the word “means” is presumed not to invoke a means-plus-function analysis, that presumption may be overcome if the limitation does not “recite sufficiently definite structure” or recites a “function without reciting sufficient structure for performing that function.” Williamson v. Citrix Online, LLC, 792 F.3d 2 Section 4(c) of the Leahy-Smith America Invents Act (“AIA”) redesignated 35 U.S.C. § 112, ¶ 6, as 35 U.S.C. § 112(f). Pub. L. No. 112- 29, 125 Stat. 284, 296 (2011). Because the ’703 patent has a filing date before September 16, 2012 (effective date of § 4(c)), we refer to the pre-AIA version of § 112. 1339, 1349 (Fed. Cir. 2015). Petitioner’s expert, Russell J. Hamilton, Ph.D., testifies that “the term ‘logic’ would not be recognized by one of ordinary skill in the art as providing sufficiently definite structure for performing the claimed functions,” and that “[l]ogic can be implemented in software, in hardware, and in combinations of hardware and software.” Ex. 1021 ¶ 122. The parties provide sufficient reasoning to overcome the presumption against a means-plus-function construction, and we accordingly construe “first logic” and “second logic” in accordance with 35 U.S.C. § 112 ¶ 6.” slip op. at 9

“untenable because its broad identification only of “computer software and/or computer hardware” as structure for performing the recited function is too generic. The law regarding construction of means-plus-function limitations as applied to computer-implemented elements is well-established: For computer-implemented means-plus-function claims where the disclosed structure is a computer programmed to implement an algorithm, “the disclosed structure is not the general purpose computer, but rather the special purpose computer programmed to perform the disclosed algorithm.” . . . This court permits a patentee to express that algorithm in any understandable terms including as a mathematical formula, in prose, . . . , or as a flow chart, or in any other manner that provides sufficient structure. Finisar Corp. v. DirecTV Group, Inc., 523 F.3d 1323, 1340 (Fed. Cir. 2008) (citations omitted). Patent Owner’s proposed construction is superior because it identifies the algorithm through explicit reference to the flow chart of Figure 4 and related disclosure in the Specification. Patent Owner’s position is supported by testimony of its expert, Sasa Mutic, Ph.D., who refers to those disclosures in opining that “the [’703] patent describes a process of steps for obtaining the result of properly positioning a patient to begin a treatment” and that “Fig. 4 of the [’703] patent provides a flowchart of a process for use of an embodiment of the invention.” Ex. 2012 ¶ 69. Petitioner takes the position that the ultimate scope of the corresponding algorithm “does not matter” because Petitioner contends that the challenged claims are unpatentable even under Patent Owner’s proposed construction. Pet. Reply 315, 3. Nevertheless, Petitioner attacks Patent Owner’s proposed construction as “implicitly adopt[ing]” two “additional but unreasonable limitations.” Id. First, Petitioner contends that “the claims do not require the performance of the function of the second logic to be fully automated and instead permit human interaction with the second logic.” Id. Second, Petitioner contends that blocks 520 (“Position Patient”), 525 (“Register Treatment Image Data with Simulator/Reference Image Data and Reposition Patient”), and 530 (“Position Clinical Treatment Machine”) of Figure 4 “need not be performed in their entirety by logic so long as the second logic is used for some step in each block.” Id. at 4. We find no inconsistency in these positions with Patent Owner’s proposed construction. In light of the foregoing considerations, we adopt Patent Owner’s proposed construction.” slip op. at 14
