“But before describing the embodiments cited by Patent Owner, the Specification plainly states: “Any terms not expressly defined herein have their conventional meaning as commonly understood by those having skill in the relevant art(s).” Ex. 1001, 4:64–67. Thus, the Specification itself cautions against construing the claim terms such as “secure identifier” as limited to the scope of the disclosed embodiments. Here, Patent Owner has not cited any express definition of “secure identifier,” or identified any explicit disclaimer of claim scope that might justify narrowing the scope of this claim term to specific embodiments disclosed in the Specification. In the absence of such a definition or disclaimer, we are not persuaded that the scope of the claim term “secure identifier” should be limited to specific aspects of the preferred embodiments cited by Patent Owner. See Prelim. Resp. 7–14. On this record, and at this stage of the proceeding, we decline to adopt Patent Owner’s proposed construction and preliminarily construe “secure identifier” as “a credential that can be used to securely verify the identity of a device, such as an airborne object or ground-based transmitter.”8” slip op. at 10
- Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateNot entitled to earlier dateDecided for petitioner
“’071 Application lack adequate written description support for the “secure identifier” claim limitation. For a patent claim to be entitled to the priority date of an earlier-filed application, the earlier application must provide complete written description support for the claim as required by 35 U.S.C. § 112(a). L.A. Biomedical Rsch. Inst. at Harbor-UCLA Med. Ctr. v. Eli Lilly & Co., 849 F.3d 1049, 1057 (Fed. Cir. 2017) (“L.A. Biomed”). To satisfy this requirement, the written description must “reasonably convey” to a person of ordinary skill in the art that the inventor had possession on the claimed priority date of each limitation of the later-claimed subject matter. L.A. Biomed, 849 F.3d at 1057. It is not enough that an earlier application’s disclosure “renders the later-claimed invention obvious;” as “the disclosure must describe the claimed invention with all its limitations.” L.A. Biomed, 849 F.3d at 1057. On this record, we agree with Petitioner that the ’153 Provisional and ’071 Application lack adequate written description support for the “secure identifier” limitation of claim 21. We have preliminarily construed “secure identifier” as “a credential that can be used to securely verify the identity of a device, such as an airborne object or ground-based transmitter.” See supra § II.B. As discussed above, the Specification of the ’959 Patent does not use the term “secure identifier,” but the Specification contains extensive discussion of the need for an identification credential that is secure (e.g., difficult for a bad actor to clone or impersonate). See, e.g., Ex. 1001, 1:56– 65 (discussing the need for a system that is difficult to “clone”), 10:20–49 (discussing the need “trust” between a drone and ground-based equipment, and the need for a way to verifying the drone’s credentials), 11:5–12:62 (disclosing the use of encryption and a rotating SSID to generate a secure identifier for a drone). None of the portions of the Specification cited above is present in the ’153 Provisional or the ’071 Application. See generally Ex. 1006, 1007. The ’153 Provisional and ’071 Application discuss the need for identifiers for low-altitude aircraft (see, e.g., Ex. 1006, 2; Ex. 1007, 9), but there is no discussion of any need for an identification credential to be secure or resistant to cloning or impersonation. See generally Ex. 1006, 1007. The ’153 Provisional and ’071 Application do not disclose the use of encryption, SSIDs (much less rotating SSIDs), or any other technologies for the purpose of verifying the authenticity of an identification credential. See generally id. Based on our review of the ’153 Provisional and ’071 Application, we preliminarily conclude that neither of these applications would have reasonably conveyed to a person of ordinary skill in the art that the inventor then had possession of the concept of the “secure identifier” that was later claimed in the ’959 Patent.” slip op. at 12

If Boolean modifiers are excluded from the definition of a “string separator character,” then the Londergan Search Bar and Search Builder features, which accept only Boolean operators, do not teach or suggest 16 As Patent Owner argues, the intrinsic evidence does not support this interpretation of the claim language.

Even Petitioner acknowledges in a footnote that it may not be appropriate to include the Boolean AND operator in the definition of “string separator character.” Petitioner argues: To the extent Patent Owner argues the Boolean AND operator is not a string separator character (which Petitioner does not acquiesce is appropriate), it would have been obvious to a POSITA when implementing Raskin’s teachings to perform the search incrementally to use a single-character string separator character, such as a plus sign, as was known in the art (e.g., EX1057, 60, 109, 129, 151), or a comma, as described by the Lotus Notes references (EX1059, 159-165), at least because a POSITA knew that a goal of the incremental search is to minimize the number of characters the user has to enter before obtaining the desired search results. Pet. 24 n.7. limitation [1.10].17 See Ex. 1061, 140–42. The Wilcox Search Bar similarly is limited to strings separated by a Boolean operator. See Ex. 1059, 160–62.

Id. at 163 (“If you want to search for documents that contain all of several words, type them in this box, separated by commas.”).

“extreme technical difficulties with even using incremental searches.” Prelim. Resp. 21, 25 (citing Ex. 1021, 126). Patent Owner argues that “[a] POSITA is not motivated to undertake a modification of the prior art with something that the art teaches would be difficult or impossible to do.” Id. at 21 (citing Natera, Inc. v. NeoGenomics Labs., Inc., 106 F.4th 1369, 1377–78 (Fed. Cir. 2024)). We do not interpret Raskin in this manner. Patent Owner points to a passage in Raskin stating, “almost all interface-building tools make it easy to implement delimited searches and difficult or impossible to implement incremental searches.” Ex. 1021, 126. There is a difference, however, between “difficult to implement” and “difficult to use.” For the end-user, Raskin concludes that “[f]rom the point of view of interface engineering, the advantages of incremental searching are so numerous and the advantages of delimited searches so few that I can see almost no occasions when a delimited search would be preferred.” Id. at 126 & n.7 (“A search is either incremental or excremental.”). It is reasonable to conclude that one of ordinary skill would have been motivated to choose a search method that offered numerous advantages to end-users. Finally, Patent Owner argues that “Raskin’s entire philosophy to user interfaces was incompatible with Lotus Notes.” Prelim. Resp. 22–25. According to Patent Owner, “Lotus Notes is all about centralized collaboration around documents, files, and file structures[,]” while Raskin “goes in a completely different direction, espousing the elimination of filenames and ‘hierarchical file structures’ including directories and folders.” Id. at 23 (citing Ex. 1021, 119). Patent Owner claims that modifying the Lotus Notes references with Raskin would “effectively render[] Lotus Notes’ functionality of hierarchical viewing of and responding to documents unusable.” Id. Petitioner, however, does not propose to incorporate Raskin’s views on hierarchical file structures into the combination of Wilcox and Londergan. It is not necessary for the entirety of Raskin’s teachings to be physically compatible with the Lotus Notes systems described in Wilcox and Londergan. Orthopedic Equip., 702 F.2d at 1013 (“Claims may be obvious in view of a combination of references, even if the features of one reference cannot be substituted physically into the structure of the other reference.”); In re Sneed, 710 F.2d at 1550. Raskin is cited for one purpose: its teachings regarding incremental search.

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

But on this record, they appear, at least preliminarily, to be equivalent. As Petitioner explains, both structures utilize a rotatable cam with pins to translate a driver (driver member 90 of the ’167 Patent and hammer 6 of Lai) into a position where the driver is ready for use.

“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).

“Reviewing the written description, we find no lexicographical definition or disavowal related to “owner identification information” in the ’404 patent.

Claim 8 of the ’404 patent recites that “owner identification information includes a name and a description of the owner of the mobile device” but, as Petitioner notes, the doctrine of claim differentiation suggests the term as used in claim 1 should be construed more broadly.

“After review of the ’404 patent’s description, we find no disclosure that pressing the panic button together with another button causes the panic button to ready itself to perform functions (1) and (2) as recited in limitation 1[d]. The closest descriptions we find to limitation 1[d] are that the safety switch readies the panic button to contact 911 (Ex. 1001, 6:59–62), that the panic button may be activated by pressing the panic button with another button (id., 3:59–67, and that the panic button may start a speech recognition process that can trigger the device (id., 7:61–62). Consequently, claim 1 is itself the best source for determining what the claim language means. We determine that the ordinary and customary meaning of the “ready itself” feature of claim 1 is that the panic button “prepares itself to be triggered to perform the panic button functions (1) and (2).” Since the intrinsic evidence is sufficiently clear to discern the meaning of the “ready itself” limitation, we do not resort to extrinsic evidence.

“Thus, the ’353 application describes that moving the safety switch into position readies the panic button to contact 911, which is not the same as the panic button being activated to ready itself to perform functions (1) and (2) required by claim 1 of the ’404 patent. Patent Owner’s reliance on disclosures elsewhere in the ’353 application is unavailing.

For example, while the ’353 application does mention voice activation with a codeword and activation by depressing of the panic button together with another button (see, e.g., Ex. 1006, 17, 21, 24–25), it does not mention that depressing the panic button together with another button causes the panic button to ready itself to perform recited functions (1) and (2). The application explains that “[t]he [panic] button can send a signal to a controller inside the device to activate [the code word activation] process” and “[t]he [panic] button can start the speech recognition process in one embodiment, to trigger the device.” Ex. 1006, 25. But that describes readying the device for activation by the code word, not readying the button to perform the recited functions. The ’353 application also mentions the word “ready” in relation to using a self-defense mechanism such as pepper spray, which does not appear to be related the readying of the panic button recited in claim 1. Ex. 1006, 15, 19–20. Petitioner has thus met its burden to demonstrate that claims 1–8 of the ’404 patent lack written description support for a panic button adapted to “ready itself” to perform the recited functions because the limitation is not present in the ’353 application to which the ’404 patent claims priority.3 Pet. 8–10.

“DiPerna964 discloses a separate “safety” switch that readies the panic button to contact 911 upon being pressed (Ex. 1028 ¶ 41), but there is no mention of pressing the panic button together with another button to cause the panic button to “ready itself” to perform panic button functions (1) dialing a public or private network for an emergency purpose and (2) activating the transmitting unit, as limitations 1[d] and 1[e] require. DiPerna964 mentions pressing two buttons together to activate the panic button (see, e.g., Ex. 1028 ¶¶ 17, 23–25, 27), but not to “ready itself” to perform recited functions (1) and (2). Petitioner relies on Strack’s triggering the collection of audio, video, and location data for transmission to a remote location as equivalent to a panic button readying itself to, when activated, perform the panic button functions (1) dialing a public or private network for an emergency purpose and (2) activating the transmitting unit. Pet. 15–17 (citing Ex. 1002 ¶¶ 76–88). We do not agree with Petitioner’s contention because Petitioner fails to explain how Strack’s button press that collects and then transmits audio, video, and location data would ready the panic button to perform recited functions (1) and (2). It appears that Strack’s button press readies the device, not the button, to perform the functions. As neither DiPerna964 nor Strack nor their combination teach or suggest limitations 1[d] and 1[e], we determine it is unnecessary to proceed further with the obviousness analysis. PAR Pharm., Inc. v.

Rolabo, S.L., 437 F.3d 1157, 1164 (Fed.Cir.2006) (stating that we consider motivation to combine and reasonable expectation of success only “if all the elements of an invention are found in a combination of prior art references”)).” slip op. at 21

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
