“29. In my opinion, the POSITA at the time of the alleged invention of the Asserted Patents would have had a (1) a Bachelor’s degree in a pertinent discipline, such as computer science, electric engineering, computer engineering, or a related field and (2) have 2–4 years of experience in working with computing devices and have an understanding of indexed search systems utilized by such computing devices. 30. I am aware that Petitioner has provided its own definition . . . . 31. I believe Petitioner’s definition is not meaningfully different from my definition of a POSITA. My opinions would not change regardless of which definition of POSITA is applied. Ex. 2001 ¶¶ 29–31. In our Decision on Institution, we adopted Mr. Haeberli’s formulation, finding it to be consistent with the evidence then of record, including the asserted prior art and the ’490 patent. Dec. 9. Following a review of the full record, we agree with Mr. Haeberli’s statement that Petitioner’s definition of one of ordinary skill in the art is “not meaningfully different” from Mr. Haeberli’s for the purposes of this proceeding. We continue to view Mr. Haeberli’s proposed definition as consistent with the ’490 patent and the asserted prior art, and we apply it in our analysis below. However, our analysis of the issues below would have been the same had we instead adopted Petitioner’s proposed definition.” slip op. at 9

“In our Decision on Institution, the only term that we found it necessary to construe was the term “string separator character” in claim 1. We preliminarily construed this term to mean “a single-character string separator.” Dec. 11, 30–31. We invited the parties to address the appropriateness of this construction over the course of the trial. Id. at 11, 31. In its briefing, Patent Owner agrees with the Board’s preliminary construction, arguing that it is “consistent with the intrinsic evidence.” PO Resp. 8 (citing Ex. 1001, claims 8 and 20). Patent Owner further argues that a person of ordinary skill would have understood a multi-character Boolean operator such as “AND” to be “a search syntax instruction rather than a string separator.” Id. at 9 (citing Ex. 1059, 162; Ex. 2001 ¶ 112). Petitioner’s Reply Brief does not address the issue of claim construction. See generally Reply Br.; see also Pet. 11 (“Unless otherwise noted, Petitioner applies the plain and ordinary meaning of all claim terms below.”). Following our review of the full record, we determine that it is not necessary to construe this or any other claim term for the purposes of this Decision.2 See Nidec Motor Corp. v.

- Expert testimonyPetitioner expert discountedPatent owner expert creditedDecided for patent owner
“Having reviewed the evidence of record, we find Mr. Haeberli’s testimony to be more persuasive and better supported by the evidence. According to Dr. Terveen, “[r]obust programming languages such as C and C++, together with well-developed operating system and UI frameworks, . . . allowed an ordinary programmer to build a UI that supported incremental searching, as evidenced by the numerous prior art systems that implemented such functionality, including Entourage, Eudora, Emacs, Canon Cat, SwyftWare, and others. Ex. 1100 ¶ 43 (citing Ex. 1004, 8–9, 161; Ex. 1021, 125, 127, 129; Ex. 1039, 102–103; Ex. 1043, 385–389). The relevant question, though, is not whether it would have been possible to build a user interface that supported incremental search, but whether it would have been “simple and straightforward” to execute an incremental search of multiple partial search strings on large, indexed multi-file databases such as those described in the Lotus Notes references, as Dr. Terveen alleges. None of the prior art discussed in the “State of the Art” section of Dr. Terveen’s initial declaration, taken individually or together, discloses incrementally searching a plurality of files using two partial search strings. See Ex. 1003 ¶¶ 32–33, 37, 40; Ex. 2001 ¶ 100. Thus, creating a user interface might be “simple,” but the evidence suggests that the back-end execution of an incremental search is not. See, e.g., Ex. 1021, 126 (Raskin, concluding that “almost all interface-building tools make it easy to implement delimited searches and difficult or impossible to implement incremental searches”).” slip op. at 23
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable
“different approach from that taken in Lotus Notes. The difference between Raskin’s sequential scanning method and the index-based system described in Wilcox is that sequential scanning by definition can only scan one document at a time as each document is loaded into a “buffer.” See, e.g., Ex. 2020 ¶ 35. Lotus Notes, however, only needs to load the index into memory for a user to be able to locate the single index entry identifying all instances of an indexed term across all indexed files. In fact, Raskin acknowledges that indexing may be necessary to maintain an acceptable response time. Ex. 1021, 132 n.10; see also id. at 129 (indexing speeds search times). Mr. Haeberli’s third and final reason for concluding that one of ordinary skill would not have been motivated to combine Raskin’s incremental search with Lotus Notes is that at the time using incremental searches would have presented “extreme technical difficulties.” Ex. 2001 ¶ 101. Here again we find Mr. Haeberli’s explanation more persuasive than Dr. Terveen’s opinion that combining the teachings from Raskin with Lotus Notes’ teachings “would have required only simple and straightforward software modifications.” Ex. 1003 ¶ 80. According to Mr. Haeberli, “there are serious technical challenges with implementing the complex search strategies of the challenged claims in the systems on which Dr. Terveen relies.” Id. ¶ 96. As Patent Owner argues: searching across a set of files to find specific files requires the system to identify which files are in the set, access those files (which are often not loaded in active memory), search their contents, determine which files contain matches to search criteria, and then present results to the user; all tasks that do not exist in the same way (or at all) for a search confined to text in a single open file already loaded into memory. Sur-Reply 9; see Ex. 2020 ¶¶ 15, 35–36. There would have been other challenges as well. For example, “[t]he type of sequential scanning typically employed to search a single open document is very time and resource intensive if employed to search a large set of documents.” Ex. 2020 ¶ 15. Also, “[i]mplementing incremental search in the Lotus Notes indexed system would necessarily require a larger index, which would slow down, rather than increase the search speed.” PO Resp. 23; see Ex. 2020 ¶ 33. Finally, Raskin itself concludes that “even if incremental searching is advantageous, ‘almost all interface-building tools make it easy to implement delimited searches and difficult or impossible to implement incremental searches.’” Ex. 2001 ¶ 96 (emphasis added by Mr. Haeberli) (quoting Ex. 1021, 126). In short, Mr. Haeberli presents three significant reasons why there would have been no motivation or expectation of success in combining the teachings of Wilcox with those of Raskin. Dr. Terveen’s opinion to the contrary, on the other hand, is not supported by evidence. Dr. Terveen testifies that “[a] POSITA would have been motivated to perform Lotus Notes’ multi-string search incrementally for the reasons stated by Raskin: speed, effectiveness, and ease of use.” Ex. 1003 ¶ 78 (citing Ex. 1021 ¶¶ 125–127). The evidence, however, not only fails to support Dr. Terveen’s testimony, but also demonstrates that one attempting to make the proposed combination would not have reasonably expected the proposed combination to result in greater speed or effectiveness.” slip op. at 27

AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). See 37 C.F.R. § 42.100(b). Under that standard, we generally give claim terms their ordinary and customary meaning, as would be understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history. See Phillips, 415 F.3d at 1313–14.

“The ’286 patent uses the term “heavy chain” or “heavy chains” repeatedly; however, we find no express definition of the term. See generally Ex. 1001. Rather, the ’286 patent uses the term “heavy chain” in relation to antibody structure in a way that suggests the term is standard and well known in the art. See, e.g., id. at 3:19–59 (Background). The parties’ briefing on the technology reinforces this fact. See Pet. 5–14 (“The basic structure of natural IgG comprises four protein chains—two identical heavy chains (shown in red) and two identical light chains (shown in blue)—which are arranged in a Y-shaped configuration: . . . (EX1013, 112-13; EX1002, ¶¶23-30.)”); Prelim. Resp. 3–4 (“Natural or wild type Igs have a particular structure made of two identical light (L) chains and two identical heavy (H) chains. See EX2008 at ¶ 23. Each Ig heavy chain consists of three constant domains (CH1, CH2, and CH3) and one variable domain (VH), which is also isotypes, or a functional derivative and/or fragment of these. In a preferred embodiment, Ig-like molecules are produced that are antibodies of the IgG isotype because IgG antibodies e.g. have a longer half life as compared to antibodies of other isotypes. Ex. 1001, 11:9–21. As noted above (see supra Section I.C), IgG antibodies’ heavy chains have three constant domains, but IgE and IgM have four. Thus, Patent Owner’s argument that heavy chain means one variable and three constant domains, and two differently-binding Fab arms, ignores embodiments of the invention. consistent with the definition of heavy chain in the ’286 Patent. See EX2008 at ¶ 24; EX1001 at 11:58–66.”). This is also how the ’286 patent generally uses the term. See Ex. 1001, 11:58–12:1. But, the Specification does not limit its embodiments to only IgG antibodies because it also describes that the invention may be “IgG1, IgG2, IgG3, IgG4, IgA, IgE, and IgM” type antibodies, and fragments. Ex. 1001, 11:9–21; see also supra n.10 (quoting the ’286 patent’s definition of antibody). Other embodiments would not necessarily have the heavy chains as argued by Patent Owner. There is no evidence of record that the ’286 patent’s claims or the Specification generally use or limit the term “heavy chains” (or “heavy chain”) in any way deviating from its ordinary and customary meaning in the art. Therefore, at this stage of the proceeding, we decline to expressly interpret this claim language. 2. Summary on Claim Construction At this stage of the proceeding, we expressly construe no claim terms and give each claim term the ordinary and customary meaning it would have had to the person of ordinary skill in the art as of the invention date. See Nidec Motor Corp., 868 F.3d at 1017. If either party intends to further argue claim construction at trial, they should do so in a clearly designated section of their briefing so as to expressly identify such arguments. See, e.g., 37 C.F.R. § 42.104(b)(3) (content of petition); see also Board’s Consolidated Trial Practice Guide (CTPG) at 46, 48–45 (Nov. 2019).12 Claim construction arguments should not be relegated to patentability arguments on the facts.” slip op. at 16

“In brief summary, these limitations require one CH3 heavy chain to have a positive amino acid substituted in place of a neutral one, the other CH3 heavy chain to have a negative amino acid substituted in place of a neutral one, and that when the heavy chains are expressed by culturing the host cell these positive and negative amino acids interact and the antibody produced is a heterodimeric antibody. Petitioner asserts that Lazar expressly teaches engineering two CH3 domains so that, when expressed, they interact and form a heterodimeric CH3 interface by making neutral-to-positive and neutral-to-negative amino acid substitutions at known interacting residues on each CH3 domain, e.g., S364E (changing neutral serine to negative glutamic acid at residue 364) on one CH3 domain, and L368K (changing neutral leucine to positive lysine at residue 368) on the other CH3 domain; or T366D (swapping neutral threonine for negative aspartic acid at residue 366) on one CH3 domain and L351K (swapping neutral leucine for positive lysine at residue 351) on the other CH3 domain; that these residues were known in the art to be respective interfacing contact residues; that these modifications favor Fc heterodimerization; and that they result in a heterodimeric antibody (proof-of-concept shown by synthesizing and screening).

Petitioner further asserts, however, that it would have been obvious “to replace Haley’s hydraulic lifter with the claimed ‘lifter,’ disclosed by [Lai]”. Pet. 13. (citing Ex. 1003 ¶ 54). Dr. Vallee’s cited Declaration testimony provides his opinion on this issue, which is consistent with Petitioner’s argument. Petitioner also asserts that “Lai discloses an electrically-powered, mechanical lifting mechanism with a structure that is essentially identical to the ‘lifter member’ disclosed in the ’776 patent.

“Petitioner asserts the term “lifter member” in the claims of the ’776 patent is “a means-plus-function term” because the claims “lack any ‘recital of structure, material, or acts in support thereof’ for the ‘lifter’ element.” Pet. 7 (citing 35 U.S.C. § 112(f)). Petitioner also asserts “[t]he Federal Circuit held that the term ‘lifter member’ in the related patents is a means-plus-function term subject to §112(f).” Pet. 7. Petitioner cites no authority for this assertion. We understand this assertion to refer to the decision in Kyocera Senco Indus. Tools Inc. v. Int’l Trade Comm’n, 22 F.4th 1369 (Fed. Cir. 2022), identified by Petitioner as a related matter. Pet. 2. In this case, which involved patents from the same family as the ’776 patent (see Section I.C of this Decision), the Federal Circuit concluded that “§ 112 ¶ 6 applies to the ‘lifter member’ limitation, and it must be construed to cover only ‘the structure, materials, or acts described in the specification as corresponding to the claimed function and equivalents thereof.’” Id. at 22 F.4th 1379–1381. “Where multiple patents derive from the same parent application and share many common terms, we must interpret the claims consistently across all asserted patents.” Samsung Elecs. Co. v. Elm 3DS Innovations, LLC, 925 F.3d 1373, 1378 (Fed. Cir. 2019) (citing SightSound Techs., LLC v. Apple Inc., 809 F.3d 1307, 1316 (Fed. Cir. 2015) (internal quotation marks omitted). Patent Owner asserts that Petitioner: fails to comply with the requirement of 37 C.F.R. § 42.104(b)(3) to specifically identify the structure in the specification associated with that element. As ‘lifter’ is present in every challenged claim under all four grounds, Petitioner’s failure to provide a claim construction for ‘lifter’ is fatal to its Petition. Prelim. Resp. 13. We disagree. First, the claims in the ’776 patent do not use the single word “lifter” alone. The term used in some of the claims, see, e.g., independent claims 1 and 17, and the claims dependent from claims 1 or 17, is “lifter member.” We recognize that the written description in the ’776 patent states “the rotary-to-lifter 100 is also sometimes referred to herein as a ‘lifter member,’ or simply as a ‘lifter.’” Ex. 1001, 9:5–7. This suggests that that term “lifter” is intended to mean the “lifter member,” which makes the use of either term a distinction without a substantive difference. Moreover, neither independent claims 9 or 24, nor the claims dependent from claims 9 and 24, use the word “lifter” or “lifter member. Second, as stated in Petitioner’s Preliminary Reply, the Petition “identifies the portions of the specification that describe the corresponding structure for the ‘lifter’ when comparing its structure to that of the Lai prior art.” Prelim. Reply 1. The Petition provides a colored version of Figure 12 from the ’776 patent (reproduced below) and identifies the following corresponding structures from the Specification of the ’776 Patent: The “lifter member” of the ’776 patent includes a rotatable cam lifter 100 (yellow [ ]), with pin 104, 106, and 108 (green) on its face surface that engage protrusions 92 (blue) on the driver member 90 (orange). ’776 patent, 9:30–46, 16:34–48, Fig. 12. The ’776 patent also discloses two-pin variants: lifter members 465 and 480 in Figs. 31, 33. [citing] ’776 patent, 32:15–30, 32:48–63. Petition at 13. Based on the record before us, we determine that this identification of corresponding structure is sufficient to satisfy 37 C.F.R. § 42.104(b)(3).

“to mean “a chamber that is distinct from the displacement volume of the hollow cylinder and contains part of the working air volume during operation.” Pet. 8. According to Petitioner “there is nothing in the intrinsic record or any of the claims of the ’776 patent that prevents the ‘main storage chamber’ from being in the hollow cylinder, so long as it is distinct from its separately-recited ‘displacement volume.’” Id. at 9 (emphases added). Patent Owner asserts that “[g]rounds 2 and 4 each requires this Board to interpret the ‘storage chamber’ to be the same structure as the hollow cylinder.” Prelim. Resp. 31. According to Patent Owner, “[t]he Federal Circuit, considering both parties’ claim construction arguments, rejected that construction.” Id. Patent Owner does not provide any citation to support its reference to the Federal Circuit decision. It appears to be a reference to the Kyocera decision considering review of the ITC determination. See Kyocera, 22 F.4th at 1383. That decision, however, construed claims in a related patent to “require two distinct structures: the main storage volume and a smaller “hollow cylinder” contained within the main storage volume. Based on the record before us, Petitioner’s proposed construction is consistent with the Federal Circuit’s construction, which states two structures can be distinct even if one distinct structure is “contained within” the other distinct structure. Although the parties dispute the construction of the “storage chamber” claim limitation, this dispute relates only to Grounds 2 and 4. See Prelim. Resp. 31. We need not resolve it to determine whether to institute review. The parties are welcome to develop their arguments regarding this claim limitation during trial. 3. Conclusion Regarding Claim Construction Our claim construction analyses in this decision to institute a trial do not preclude the parties from arguing their proposed constructions of the claims during trial. Indeed, the parties are hereby given notice that claim construction, in general, is an issue to be addressed at trial. Claim construction will be determined at the close of all the evidence and after any hearing. The parties are expected to assert all their claim construction arguments and evidence in the Petition, Patent Owner’s Response, Petitioner’s Reply, or otherwise during trial, as permitted by our rules.” slip op. at 19

“gas pressure system” recited in the preamble of independent claims 1 and 17. Prelim. Resp. 21–22. Patent Owner further argues that Petitioner, through its comparison of claims 1 and 17 to Haley, improperly implies that the “gas pressure system” can be “limited to a distinct portion of a power tool.” Id. at 23. Patent Owner contends that such an interpretation is improper because the “gas pressure system” must refer to “the entire system,” because the “structure of the claims themselves . . . include[s] . . . every component of the tool.” Id. We disagree. The “gas pressure system” recited in the preambles of claims 1 and 17 expressly refers to a system that is “for a power tool” and thus does not necessarily refer to “the entire” tool or “every component of the tool.” Ex. 1001, 39:6 (claim 1), 40:51 (claim 17). Neither claim 1 nor claim 17 recites, for example, the lifter or driver, which are required elements of an “entire” tool. Id. at 39:6–22 (claim 1), 40:51–67 (claim 17). The lifter and driver are introduced in dependent claims 2 and 18. Id. at 39:23–30 (claim 2), 41:1–9 (claim 18). Still other necessary components of a tool, e.g., a motor and power source, are introduced in dependent claims 5 and 19. Id. at 39:40–42 (claim 5), 41:10–13 (claim 19). By contrast to claims 1 and 17, independent claims 9 and 14 recite a “portable fastener driving tool” and expressly recite many necessary components of such a tool including the driver, lifter, prime mover, and power source. Id. at 39:54 (claim 9), 40:20 (claim 14). Accordingly, we find that the “gas pressure system” of claims 1 and 17 broadly refers to a portion of a power tool rather than the “entire system” or “every component of the tool.” slip op. at 8

“Patent Owner further argues Nakazawa teaches away from Petitioner’s asserted modification in which Glaug’s lower non-perforated layer is added to Nakazawa’s diffusion sheet. Prelim. Resp. 42. Specifically, Patent Owner argues Nakazawa teaches that its embodiment in which the second absorbent material is wrapped in a hydrophilic sheet has the advantage of preventing leakage of super absorbent polymer (“SAP”) from the second absorbent material without impeding permeation of excretory fluid through the hydrophilic sheet. Id. at 43 (citing Ex. 1008 ¶ 85, Fig. 15). Patent Owner further relies on Petitioner’s argument that Nakazawa’s hydrophilic layer is analogous to the lower non-perforated layer in Glaug. Id. (citing Pet. 93–94). Therefore, Patent Owner argues, Nakazawa teaches that Glaug’s fluid acquisition system would impede permeation of fluid rather than promote it. Id. Patent Owner’s teaching away argument is unavailing based on the current record. Patent Owner improperly relies on Petitioner’s contention in its anticipation challenge based on Nakazawa, and characterizes it as an argument about Glaug. As further discussed in Section II.G below, Petitioner’s anticipation challenge is based on analogizing Nakazawa’s hydrophilic sheet to a core wrap feature identified in Patent Owner’s infringement contention in parallel district court litigation. See Pet. 92–93. Contrary to Patent Owner’s argument, Petitioner’s obviousness contention does not argue Nakazawa’s hydrophilic layer is analogous to Glaug’s nonperforated fibrous layer.
