“Dr. Mowry further attests that “A POSITA would have understood Glines’s disclosure of providing content from an origin source would have included supporting more than one origin source (e.g., more than one website or content provider[)].” Ex. 1008 ¶ 262 (citing Ex. 1002, 12:11–22 (storing replica files that originate at an origin server 40), 13:21–14:3 (requesting “example.com”)). That statement, however, goes only to what Glines might be capable of doing, not to whether one would have modified Glines to do so. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (“[o]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed inventions.”). Dr. “content providers” limitation, stating that it “would have been nothing more than replicating Glines’s teaching of storing and providing content associated with one origin server, with expected results.” Ex. 1008 ¶ 263. That statement, however, is unsupported, and moreover, does not explain how such replication would occur or what results would be expected. Prelim. Resp. 25–26. At this stage in the proceeding, Dr. Mowry’s testimony amounts to a “conclusory generalization” that does not provide the “reasoned explanation” sufficient to show that a limitation missing in the cited art was taught by the knowledge in the art.

“CLAIM CONSTRUCTION B. In an IPR, we construe a patent claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b). This generally includes “construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” Id. The ordinary and customary meaning of a claim term “is its meaning to the ordinary artisan after reading the entire patent,” and “as of the effective filing date of the patent application.” Phillips, 415 F.3d at 1313, 1321. Neither Petitioner nor Patent Owner argues that we need to construe any claim terms explicitly. See Pet. 2–3; Prelim. Resp. 9. However, the parties’ positions depend on interpreting the claim language in a particular way, and we discuss the relevant claim language below in the context of the parties’ arguments regarding the prior art.

“At this stage, we find Petitioner’s arguments persuasive and disagree with Patent Owner. Patent Owner appears to equate a “fabrication profile” with a toolpath description, but nothing in the plain language of claim 1 supports that narrow interpretation. The ’774 patent describes a “fabrication profile” broadly and states that the profile can simply “include the dictionary [of configuration information],” or be “used to determine which machineready representation is available or suitable for a target printer.” Ex. 1001, 23:49–52. The preliminary evidence suggests that Douglas’s “operational parameters” would count as a “fabrication profile” because it is “the basis for generation of a machine-ready representation of the three-dimensional model that is executable on the target printer.” Id. at 23:37–39; see infra Section III.C.8. We also disagree that Petitioner’s argument is impermissible hindsight, because it is based on the disclosures in Douglas and Mark, and Petitioner has articulated a sufficiently persuasive reason to combine those references without referring to the ’774 patent itself. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”). Finally, Petitioner appears to rely on Mark for providing a particular example of a fabrication profile, not to replace Douglas’s overall system in which the 3D printer can receive “operational parameters” rather than just G-code. See Pet. 8–10, 17–23; see also Ex. 1005 ¶ 41 (the print queue, which stores tool instructions, may be maintained locally on printers 204 or on print servers 208); see In re Mouttet, 686 F.3d 1322, 1332 (Fed.

“We note that, as discussed below, we are able to determine whether to institute inter partes review of the ’713 patent without expressly construing the term “from multiple print heads or deposition lines.” See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

As for Patent Owner’s argument that Petitioner has failed to carry its burden to identify how the claims are to be construed, we disagree on the present record. Although Petitioner does not provide a preferred construction for the single term it proposes requires construction, Petitioner does identify which of its two alternative constructions applies to each of its asserted grounds of unpatentability. Pet. 6 (“Under the first construction, [the obviousness grounds] are applicable, and [the anticipation ground] would be excluded from the claim scope. Under the alternative construction, all of [the asserted grounds] are applicable.”).

“limitations of clauses 1.3 and 1.4, but concedes that Haley does not disclose that its driver member has “at least one longitudinal edge with a plurality of spaced-apart protrusions,” as required by clause 1.4. 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. Pet. 13. Petitioner provides side-by-side colored figures from the ’776 patent and from Lai, reproduced below, to illustrate its argument. Pet. 14.

“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). We also note that at this stage of the proceeding, Patent Owner does not dispute that Petitioner has identified the correct corresponding structure.

“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

Patent Owner argues, however, that Petitioner has “fail[ed] to identify any structure in the ’007 Patent to perform the claimed function.” Prelim. Resp. 10. We disagree.

“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

“On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms. See e.g., Ex. 1001, 10:17–11:14, 12:65–13:8, 14:20–24.

“We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard.
