    “iv. Claim 1 Conclusion Based on the complete record presented, Petitioner has shown that Gage teaches all limitations of claim 1. Thus, we determine that Petitioner has shown by a preponderance of the evidence that the subject matter of claim 1 would have been obvious over Gage. v. Independent claim 8 Independent claim 8 recites a method of “providing situation related information to a situation authority via a situational network,” wherein the method comprises “receiving, by a participant device, a roll call query soliciting a reply related to a status of a participant based on the participant being determined, by the situation authority, to be geographically proximate to the situation,” “receiving, by the participant device, a selection of a status response from the participant,” and “sending the status response to the central authority, wherein the status response is included in a roll call list.” Ex. 1001, 34:46–57. Petitioner generally refers to its contentions with respect to claim 1. Pet. 34–36. In particular, Petitioner contends that Gage teaches a subscriber device that communicates a status indicator to the disaster response system through a subscriber status reporting system that implements a “situational network” configured for use during disasters. Id. at 34 (citing Ex. 1005 ¶¶ 19, 25). Petitioner additionally contends that Gage’s “disaster response system” is a “situation authority” because the disaster response system detects an occurrence of a disaster affecting a region, receives and aggregates information related to the disaster, and then provides the information to various participants in the network.

    “repeatedly emphasized that an indefinite article “a” or “an” in patent parlance carries the meaning of “one or more” in open-ended claims containing the transitional phrase “comprising.” That “a” or “an” can mean “one or more” is best described as a rule, rather than merely as a presumption or even a convention. The exceptions to this rule are extremely limited: a patentee must “evince[ ] a clear intent” to limit “a” or “an” to “one.” The subsequent use of definite articles “the” or “said” in a claim to refer back to the same claim term does not change the general plural rule, but simply reinvokes that non-singular meaning.

EX2010, 52:3–54:5. Any of these connection points would be a trivial modification of Richardson’s embodiment. A PHOSITA would have understood how to implement this type of well-known configuration of an external battery charger and associated charging circuitry, which would have been as simple as wiring connections to the terminal anode and cathode of the batteries. The simplicity of this connection is why it is not surprising that Richardson describes such a pathway and leaves it “not shown” in the figures. Id.

Petitioner further alleges that the addition of a USB input circuit would provide for an alternative where traditional charging methods are lost, damaged. or otherwise unavailable. Id. at 45 (citing Ex. 1003 ¶ 88). Thus, Petitioner has provided sufficient reasoning with rational underpinnings to explain why a person of ordinary skill in the art would have modified the teachings of the applied references. See KSR, 550 U.S. at 418. We acknowledge, but are not convinced by, Patent Owner’s arguments that the nature of Richardson requires the ability to charge a high capacity battery and rapid recharging and therefore would not have led a person of ordinary skill in the art to include Zhao’s USB charging circuit in Richardson. See PO Resp. 25–31. In particular, we are not persuaded that Richardson is limited to high capacity, rapid recharging of batteries as Patent Owner suggests. Instead, Richardson broadly describes “an apparatus and method for temporarily delivering supplemental power to the electrical system of a vehicle” (Ex. 1005 ¶ 6) where “[t]he jump starter 10 may be configured for 12, 18, 24, 30, 36, 42 or 48 volts” (id. ¶ 34). According to Richardson, this may be achieved by using “two or more batteries of the same or different voltage levels . . . to achieve the voltage requirements of the vehicle to be started.” Id. By way of example, Richardson states that “if the batteries 23 are both 12-volt batteries, the system may be configured for 12- or 24-volt operation” and “[i]f the batteries 23 are 12-volt batteries and a battery 25 is a 6-volt battery, 18- or 30-volt configurations may be provided.” Id. Neither Richardson’s claims nor its specification require any particular charging capacity or charging time. See generally Ex. 1005. While a single, near-final paragraph of Richardson introduces the concept of rapid charging of the jump starter batteries to charge a fleet of vehicles, Richardson characterization is permissive or optional. For example, Richardson states The charging system of the vehicle may be used to charge the capacitors 21 and jump starter batteries 22. . . . This allows the capacitors 21 and jump starter batteries 22 to be fully recharged in about 1 to 5 minutes and can therefore start many vehicles in a row without becoming discharged. Id. ¶ 55 (emphasis added). We do not view this singular occurrence as supplanting the breadth of Richardson’s complete disclosure. Furthermore, the crux of Patent Owner’s argument is that because of Richardson’s goal of charging high capacity batteries a USB charger would require significant charging time. PO Resp. 29; Sur-reply 2–14 But, nowhere does Patent Owner allege that a USB charger would not work given sufficient time.11 See generally PO Resp. and Sur-reply. And, when faced with no alternative, the person of ordinary skill in the art must balance the trade-offs and consider charging slowly, or not at all. Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (explaining that “a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine”); see also Winner 11 Petitioner in its Reply presents some evidence of charging times using a USB input charger. Pet. Reply 4–7; Ex. 1044 ¶¶ 6–12, Appendix A. Patent Owner disputes the accuracy of Petitioner’s calculations. Sur-reply 2–11. But, whether Petitioner’s calculations are accurate or not, Petitioner’s proposed alternative modification does not remove the faster charging path and instead adds the convenience and flexibility of a secondary charging method where the primary and faster charging path is unavailable.

    “We find unavailing Patent Owner’s arguments that a pseudo-wire (“a type of emulated connection”) cannot be the same as a link (“a type of physical connection between router interface”). PO Resp. 20. In particular, claim 1 does not recite any requirement that a link be a physical connection, and thus, does not require that a link differs from the emulated connection of a pseudo-wire. As discussed above, during oral argument, Patent Owner acknowledges that a link is not limited to a physical connection. See Tr. 30:6–7. The ’775 patent itself provides no definition for “pseudo-wire” to support Patent’s Owner’s construction, and Patent Owner does not point to any disclosure in the ’775 patent for such support. As Petitioner points out, the ’775 patent instead supports a construction of “pseudo-wire” as comprising multiple links, wherein “[t]he first and second links constitute a first pseudo-wire pw1” and the second “pseudo-wire ps2 consists of the first link L1 and a second link L3.” Pet. Reply 7 (emphasis omitted) (citing Ex. 1001, 6:29–43).

Id. (citing Ex. 1042 ¶ 10). Although Patent Owner argues that the POSITA has always considered a pseudo-wire as a point-to-point link set up between input and output routers (PO Resp. 5–6), claims 1 and 6 do not recite that a pseudo-wire comprises a point-to-point link set up, and there is no support in the ’775 patent for specifically defining “pseudo-wire” as and limiting the term to a point-to-point link set up.” slip op. at 12

A reason to exclude an element may be found in “statements in the specification expressly listing the disadvantages of using” that element. Santarus, 694 F.3d at 1351. Another reason to exclude may be when the specification “distinguishes among” the element and alternatives to it. Inphi Corp. v. Netlist, Inc., 805 F.3d 1350, 1357 (Fed. Cir. 2015). As the Federal Circuit explained, “[t]he common denominator of these examples [(i.e., the reasons to exclude an element)] is disclosure of the element.” Novartis Pharm. Corp. v. Accord Healthcare, Inc., 38 F.4th 1013, 1017 (Fed. Cir. 2022). More particularly, “[s]ilence is generally not disclosure.” Novartis, 38 F.4th at 1017; see also Seabed Geosolutions (US) Inc. v. Magseis FF LLC, 8 F.4th 1285, 1288 (Fed. Cir. 2021). Accordingly, “the written description requirement cannot be met through simple disregard of the presence or absence of a limitation.” Novartis, 38 F.4th at 1017. Our reviewing court further notes that “it is possible that the written description requirement may be satisfied when a skilled artisan would understand the specification as inherently disclosing the negative limitation.” Novartis, 38 F.4th at 1017 (emphasis added, footnote omitted). Thus, “it is a question whether the application necessarily discloses that particular device . . . A description which renders obvious the invention for which an earlier filing date is sought is not sufficient.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed.

    “Here, as Petitioner points out, “the Challenged Claims . . . do not recite ‘means for’ or ‘step for.’” Pet. Reply 1. As the Federal Circuit stated, when a disputed claim limitation does not employ “means for” language, the presumption is that each of the terms conveys sufficiently definite structure or act and, thus, is not subject to § 112(f). See Dyfan, 28 F.4th at 1367. Based on the record before us, this presumption that each of the terms is not subject to § 112(f) is not overcome. Although Patent Owner argues that “to claim a means for performing a specific computer-implemented function and then to disclose only a general purpose computer as the structure designed to perform that function, amounts to pure functional claiming” (PO Sur-reply 5), the question here is whether “means for” analysis under § 112(f) applies at all. That is, as Patent Owner acknowledges, we must determine first whether the claim is even claiming a “means for” performing a function, “and then” determine whether the structure designed to perform that function is a general purpose computer. Id. As set forth in MPEP § 2181, the three-step analysis in determining whether § 112(f) applies begins with determining whether a claim limitation uses 1) the term “means” or “step” or 2) a nonce term used as a substitute for “means” that is a generic placeholder. See MPEP § 2181(I). We agree with Petitioner’s contentions during oral argument that Patent Owner’s arguments appear to be “based on adding a third general purpose computer structure category that triggers MPF treatment not supported by any case law.” Tr. 32:10–12. Accordingly, although Patent Owner argues that “claim 1 invokes § 112[(f)]” (PO Resp. 8, 18), and then provides extensive arguments with supporting testimony from Dr. Jakobsson as to the algorithm defining “local, secured information” (id. at 10–20 (citing Ex. 2016 ¶¶ 18, 38–51, 53–55)) and “algorithm of control logic 250” (id. at 21–25 (citing Ex. 2016 ¶¶ 37, 58)), the presumption that each of the terms is not subject to § 112(f) is not overcome; thus, we decline Patent Owner’s invitation to proceed to determining the corresponding algorithm.” slip op. at 18

In particular, Petitioner contends that a POSITA would have been motivated to integrate a PDK and RDC into a hybrid device by recognizing that Giobbi-157 and Giobbi-139 are “directed to similar operations,” “describe similar structures for performing those operations,” and have techniques that “are compatible with each other,” wherein combining the techniques “would have worked in the same manner already described in the references.” Id. at 21–22.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionTerm construed board ownDecided for patent owner

    “We do not agree with Patent Owner that “fixed” or “configurable” requires more than what is agreed to by the parties––i.e., the characteristics and operational parameters of the endpoint are either set prior to operation or can be set during operation. We disagree that the ’972 patent defines “fixed or a configurable endpoint” as “a number of descriptive fields of the endpoint.” Rather column 8, lines 5–6, of the ’972 patent states that “[a]n endpoint is defined by a number of descriptive fields,” which speaks more about the mechanism used to establish the characteristics and operational parameters of the endpoint than it does about how “fixed” or “configurable” would be understood by a skilled artisan. And the fact that an endpoint may be defined by descriptive fields does not inform a skilled artisan that “fixed” or “configurable” requires the endpoint to allow the processing device to correctly interpret and utilize the data from the endpoint. Correctly interpreting and utilizing data may be the goal, but that goal is not turned into a requirement of the claims because the recited endpoint is fixed or configurable. Similarly, there is no basis for making that goal a requirement simply because a fixed endpoint is described as providing basic functionality and a configurable endpoint is described as being configurable by the base unit either while pairing or via the processing device. As a result, we find little merit in Patent Owner’s contention that the language “fixed or a configurable” requires a process for setting up the characteristics and operational parameters of an endpoint within a device so that the processing device can correctly interpret and utilize the data of this endpoint. Patent Owner, however, will have an opportunity during trial to further develop this contention.” slip op. at 11

    “Having considered the arguments and evidence presented by both parties at this stage of the proceeding, we are persuaded that there is a reasonable likelihood Petitioners would prevail in showing that Beel discloses or suggests to a skilled artisan a base unit having a transmitter and a first peripheral device having a receiver and at least one fixed or a configurable endpoint, where the at least one fixed or a configurable endpoint is a data source or a data sink which is able to store or emit data, of the functional device exposed or made available on the first peripheral device. Petitioners’ offers evidence, supported by its expert declarant, that the endpoints disclosed in Beel are either fixed, such as a mass storage unit with predefined characteristics, or configurable, such as a virtual audio interface that may change configuration based on driver instructions or use context. Pet. 32–33. As Petitioners point out, the ’972 patent itself acknowledges that Beel’s Figure 11 illustrates a system comprising a combination of vendor-specific and standard endpoints, and further interprets these endpoints to correspond to drivers and host applications used for functionality like screen sharing and audio streaming, which demonstrates a direct conceptual and structural alignment between the ’972 patent and Beel. Id. Furthermore, Petitioner’s evidence demonstrates sufficiently that Beel describes a peripheral device acting as a virtual composite device capable of emulating different functions—such as a USB audio speaker—while rerouting the data stream (e.g., RTP audio stream) over the network. Id. For instance, Petitioners’ evidence demonstrates sufficiently Beel discloses or suggests that audio data can be captured by a virtual sound card interface implemented within the peripheral device, re-encoded, and transmitted to the base unit for playback or synchronization with video content. Id. In addition, Petitioners have demonstrated sufficiently that Beel’s architecture supports the requirement that the endpoint of the functional device—whether it is a camera, microphone, or speaker—is made available through or exposed on the peripheral device. Id. The functional device’s capabilities are effectively rendered accessible to the processing device by way of the peripheral device, which acts as an intermediary. Id. Petitioners’ evidence demonstrates sufficiently that this exposure can occur via logical interfaces, such as USB Audio Class (UAC) virtual drivers, that allow the processing device to recognize and interact with these endpoints using standard protocols. Id. Furthermore, Petitioners show sufficiently Beel discloses that the peripheral device may include software that facilitates communication with and presentation of media content on the processing device, further demonstrating that the endpoints are not only present but also actively used for data transmission. Id. Patent Owner’s arguments, at least at this stage of the proceeding, fail to undermine Petitioners’ showing because they are largely just that–– attorney arguments––without sufficient evidentiary backing and because they lack sufficient clarity regarding how the recited claim language distinguishes Beel’s disclosed system. First, Patent Owner makes several representations that Petitioners misplace its reliance on certain teachings or suggests found in Beel and that Beel does not support the contention Petitioners make, but Petitioners’ positions are backed the testimony of Dr. Almeroth and Patent Owner offers no contradictory evidence for why a skilled artisan would understand Beel differently. And, suffice it to say that, when the declaration of Dr. Almeroth is considered in juxtaposition with the cited evidence from Beel, we have found declarant Dr. Almeroth sufficiently persuasive to demonstrate Petitioner is reasonably likely to prevail on the point. For example, Patent Owner simply argues that “there is no indication in Beel of using any fixed or a configurable endpoint of the functional device exposed or made available on the first peripheral device” (Prelim. Resp. 31), but declarant Dr. Almeroth states that “Beel discloses that a peripheral device can act as a ‘virtual audio device’ using a USB Audio Class (UAC) interface,” which “indicates that endpoints of the functional device are ‘exposed or made available on the first peripheral device’” (Ex. 1002 ¶ 130 (emphasis added); see also id. ¶¶ 128–129). Patent Owner’s argument, without any evidentiary support, does little to undermine the opinion testimony from Dr. Almeroth about what Beel’s teachings would indicate to a skilled artisan.
