“Beel actually discloses the following: [0321] On the peripheral device 32 the video packets are received at the corresponding plug and play port, e.g. the USB port 11, read by the Human Interface Driver (HID) interface handler 13, unpacked to remove HID protocol headers in an unpacker 20 and then transmitted to the communications network by a transmitter 21. The network can be wireless for example WiFi or LiFi network. [0322] Having been routed over a communications network to the base unit 33, the incoming stream is read from the communications interface such as a WiFi access point 22, unpacked in an unpacker 25, decoded in a decoder 26 and then inserted into a suitable composition such as an OpenGL based composition in the compositor 29 for display on a central display device. Ex. 1005 ¶¶ 321–322 (emphasis added to portions quoted by Petitioner). Patent Owner notes that “[t]he Petition mistakenly cites to ¶ 322 of Beel but quotes ¶ 321.” PO Resp. 20 n.3. However, it appears that Petitioner has grafted together a portion of paragraph 321 that introduces peripheral device 32 with a portion of paragraph 322, which discusses features of base unit 33. However, this grafting has been done in such a way as to convey (incorrectly) that peripheral device 32, not base unit 33, includes unpacker 25, decoder 26, and compositor 29 that process the first processed video data received by the first peripheral device to generate second video data. Dr. Almeroth’s testimony, which copies Petitioner’s incorrectly altered quotation to paragraph 322 of Beel, is unreliable as to this claim limitation and is entitled to no weight.4 Thus, Petitioner has no expert testimony on which to rely for this claim limitation.” slip op. at 19

Even if we were to consider this new argument, it would not be persuasive.

And the ’972 patent admits that Beel’s Figure 11 discloses the same endpoints depicted in the ’972 patent’s own Figure 4. Id. at 4:28–33, 16:44–67.

As additional support not separately emphasized by the parties in this connection, we note Dr. Almeroth’s technical explanation that, for data to pass from a functional device to a peripheral device, “both the functional device and the peripheral device must have ‘endpoints’”—a data source and a data sink—reasoning consistent with the ’972 patent’s definition. Ex. 1002 ¶ 125.” slip op. at 27

“First, we agree with Patent Owner that, under the ordinary meaning of the claim language, the endpoint is an endpoint of the peripheral device, and that it must be “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.” Ex. 1001, 23:11–17. The limitation thus identifies a structure—an endpoint, residing on the peripheral device, that is a source or sink and that corresponds to (is “of”) the functional device—through which the communication recited in subsequent element (g) is carried out. By its terms, it imposes no requirement as to the direction in which data flows; it requires only that the endpoint be a data “source” or a data “sink” that is able to “store or emit” data. The operative transmit-and-receive communication “from the functional device to the processing device via the . . . endpoint” is recited in subsequent element (g), which we take up separately below. The disputed question under this limitation is therefore the structural one: whether Beel discloses, on the peripheral device, an endpoint that is “of the functional device.” Because the inquiry is structural and non-directional, we are not persuaded that the audio-out orientation of Beel’s described embodiment, on which Patent Owner relies, is dispositive of this limitation. device. The ’972 patent expressly defines endpoints broadly “as data sources or sinks.” Ex. 1001, 7:64–67. And the ’972 patent admits that Beel’s Figure 11 discloses the same endpoints depicted in the ’972 patent’s own Figure 4. Id. at 4:28–33, 16:44–67. Beel’s Figure 11 and accompanying description disclose a “[m]ass storage device 12,” a “USB audio device 14,” and a “USB HID device 13” on the peripheral device. Ex. 1005, Fig. 11, ¶¶ 320–323. Patent Owner’s own declarant conceded that a mass storage device is “a type of endpoint” (Ex. 1034, 43:19–21), and that “audio devices are endpoints” (id. at 57:5–61:4). We give reduced weight to Patent Owner’s contrary position to the extent it rests on the premise that a reference cannot disclose an endpoint unless it uses the word “endpoint” (Ex. 2030 ¶ 94; Ex. 1034, 43:19–44:16, 72:18–73:12); a premise that is inconsistent with the ’972 patent’s own broad definition and with the ’972 patent’s admission regarding Beel’s Figure 11. As additional support not separately emphasized by the parties in this connection, we note Dr. Almeroth’s technical explanation that, for data to pass from a functional device to a peripheral device, “both the functional device and the peripheral device must have ‘endpoints’”—a data source and a data sink—reasoning consistent with the ’972 patent’s definition. Ex. 1002 ¶ 125. Third, we find that the endpoint Beel discloses is a data source or a data sink that is “able to store or emit data, of the functional device.” We begin with the words of the limitation. The endpoint need only be “able to store or emit data”—language of capability, not a requirement that particular data actually traverse the endpoint in operation, and still less in a particular direction. And the endpoint is defined by the character of the data it handles: it is “a data source or a data sink,” which the ’972 patent instructs An audio endpoint, so understood, is characterized as an audio source or sink; its structure is not tied to any single instance of an audio device. On that understanding, Beel’s disclosure establishes the required capability directly. Beel discloses that “audio data is captured through a virtual sound card interface added as a logical device over the physical interface provided in the peripheral device,” Ex. 1005 ¶ 43, that the peripheral device “acts as a composite device comprising for instance a (virtual) audio speaker device,” id. ¶ 317, and that “audio data is captured at this interface . . . internally in the peripheral device 32” and streamed over the communications network, id. ¶ 319. Beel thus shows the endpoint on the peripheral device actually storing and emitting audio—and, correspondingly, video—data, which is the very type of data produced and consumed by the audio/visual functional devices connected to the base unit, including the microphones, cameras, speakers, and displays. Id. ¶ 120. An endpoint shown to store or emit audio and video data is necessarily one that is “able to store or emit” such data; the capability the limitation requires is thus established by Beel’s disclosure.” slip op. at 26

The parties do appear to disagree on the meaning of “trigger,” however. Although neither party actually identifies that term as needing interpretation and neither party actually provides a claim construction analysis to support its respective position, the parties do dispute whether the evidence presented shows a “trigger,” both presumably giving that term its plain and customary meaning. In other words, while both parties appear to agree “trigger” carries its plain meaning, in application, the parties’ dispute regarding the particular limitations including that term appears to turn, not over what the evidence discloses, but only on whether the disclosure satisfies the plain meaning of “trigger” (see infra § II.E.2). Accordingly, while we apply the plain meaning of “trigger” in this proceeding, and in doing so, we address which party has properly applied the plain meaning and, in doing that, we address the scope properly afforded to “trigger.” That analysis, however, is done below in the context of the limitation in which this issue arises (see id.).” slip op. at 8

“has now been developed, and in view of both parties’ arguments, we find Petitioner has persuasively shown that modifying Ono’s peripheral device (i.e., communications module 44) to include an input device/physical actuator like the one described for Ono’s remote controller 69 to control the display of image data from a particular user’s computer would have been obvious to a skilled artisan at the time of the invention. More specifically, Petitioner has shown persuasively Ono shows that the use of an input device/physical actuator to send a signal that causes a participant’s computer to transmit and control the image data presented on a shared display in an image display system was a known technique (see Ex. 1005 ¶¶ 7, 44–48, 66– 71, 77–78, 80–89, 144, Figs. 3, 6, 8, 9; Ex. 1002 ¶¶ 85–100, 121–127) and available location for such an input device/physical actuator to initiate the transmission of data (see Ex. 1007 ¶¶ 6, 18, 20, 22–23, 26, 28, 46, Fig. 1; Ex. 1002 ¶¶ 92–100). Petitioner has also persuasively shown that a skilled artisan recognized benefits to giving a participant the ability to locally control the display of their computer’s image data. See Ex. 1002 ¶¶ 87–91; Ex. 1008 ¶¶ 4, 19–20, 27–28; Ex. 1009 ¶¶ 10–13, 39–10, 70–72. When Ono and Corbett are considered together as a whole from the perspective of a skilled artisan, therefore, it is clear that applying a similar input device/physical actuator to Ono’s peripheral device would have been recognized to result in the benefit of providing a participant with the same ability to send a signal that causes a participant’s computer to transmit and control the image data presented on a shared display from their computer within an image display system. As a result, a motivation has been established because the combination is an application of a known technique to derive a known benefit using prior art elements according to their established functions.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner
“that, from their perspective, the plain meaning of the term “trigger” does not exclude intervening steps between a user’s action on an input device and the ultimate transfer of the user selected arbitrary media content. Pet. Reply 11– 12 (indicating that “trigger” encompasses “a process that begins with and thus is triggered by a user pressing a button followed by an ‘image transfer’ from a PC to a projector”). For its part, Patent Owner maintains (at least implicitly) that intervening steps are excluded from the plain meaning. Neither party addresses with more specificity why, or why not, the scope of “trigger” supports their positions, however. Having now the complete record before us, we find that out preliminary assessment was wrong because the plain meaning of the term “trigger” does not exclude intervening steps between the cause-and-effect relationship of the trigger and the result it is intended to cause. Take, for example, a simple gun. Pulling the “trigger” to fire a gun necessarily includes intervening steps to occur: the trigger releases a hammer that, in turn, contacts a blasting cap within a bullet casing, which is what actually causes the gunpowder to ignite (i.e., fire) and expel the bullet. And there is no evidence in this record to suggest that this customary understanding of the word “trigger” is any different in the electrical arts, other than the trigger and result are generally electrical in nature, rather than mechanical. We find no clear disavowal of claim scope within the intrinsic record of the ’951 patent to indicate that the term “trigger” was intended to be understood any differently to exclude any intervening steps between a user’s action on an input device and the resulting transfer of user selected arbitrary media content. intervening steps would exist because the input device does not actually do the transferring of the media content; instead, the claims recite the transferring is “from the transmitter to the wireless communications network and [then] to the base node.” See Ex. 1001, 11:3–48, 27:62–28:1 (claim 1), 28:62–67 (claim 9), 29:42–46 (claim 16), 30:36–44 (claim 21) (emphasis added). A skilled artisan would have recognized that there would be intervening steps between the input device being acted upon and the content being displayed by base node’s display. See Ex. 1083 ¶¶ 11–12. In the claims, the input device is analogous to a gun’s trigger, the user carrying out a user action on the input device is analogous to pulling a gun’s trigger, and the transfer of user selected arbitrary media content is analogous the gun expelling a bullet. In both cases, there can be, and usually are, intervening steps, moreover, in both cases, inadvertent things can happen that may prevent the intended result (e.g., in the case of a gun, the hammer can jam; in the case of an input device, a connection can be rejected). Nevertheless, in both cases, the trigger is the thing that initiates an automated process that leads to a particular result, unless a conditional error occurs.” slip op. at 31

“term “pre-installed generic driver.” Pet. 13; PO Resp. 9–10. Those proposed constructions are consistent with the lexicographic definition provided in the ’002 patent. In a section titled “Definitions,” the ’002 patent states: The term “pre-installed generic driver” is intended to mean a driver which is installed on a processing device such as a computer as a standard driver, e.g. is installed with the installation of the operating system. Such a driver is standard for the operating system and can drive a standard class of peripheral devices coupled to or connected to the processing device. Ex. 1001, 14:32–38.

“Patent Owner’s arguments are unpersuasive. We are not persuaded that these differences between Kaplan, Ahmed, and Deforche are dispositive. To the contrary, we find the differences establish why a POSITA would have further modified Kaplan and Ahmed with the teachings of Deforche. Deforche expressly teaches that a disadvantage of wireless modems is that they require installation of an appropriate driver before applications running on the computer device can use the functionality of the wireless modem to connect to wireless networks. Ex. 1030 ¶¶ 2–3. Deforche solves this problem by using the processing device’s pre-installed drivers, which can be for a human interface device, to set up a modem/host communication interface for communication. Id. ¶¶ 4, 9. Because “[d]ata traffic from the computer device towards the wireless communication network and vice versa is routed over this modem/host communication interface and uses the generic communication protocol provided by the preinstalled generic driver,” Deforche states this “has the advantage that the need for a specific driver for the communication between the wireless modem device and the computer device can avoided” and “the advantage that a user can use the wireless modem device on a computer device on which he has no administrator rights, i.e. a computer specific driver for the wireless modem device.” Id. ¶ 9. “The motivation-to-combine analysis is a flexible one. Any need or problem known in the field of endeavor at the time of and addressed by the patent can provide a reason for combining the elements in the manner claimed.” Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1379 (Fed. Cir. 2023) (internal quotations omitted). As the Federal Circuit held, “[t]here is a motivation to combine when a known technique has been used to improve one device, and a [skilled artisan] would recognize that it would improve similar devices in the same way.” Intel Corp., 61 F.4th at 1380. Here, Deforche establishes that utilizing an operating system’s preinstalled generic driver to provide a generic protocol communications between the processing device and a peripheral device was known for improving wireless modems because it does not require administrator rights and a specific driver to be installed to enable communications between the wireless modem device and the processing device.” slip op. at 20

“it was “known to utilize ‘cues’ to help the user know what gesture to utilize and whether they are correctly performing the gesture (e.g., graphics such as movable images that help the user visualize the correct gesture and how to complete it successfully).” Pet. 40 (citing Ex. 1005, Abstract, ¶¶ 54, 62, 73). This sentence does not cure the deficiency noted above regarding Petitioner’s reliance on Ahn’s graphic shadow moving with a gesture. Chaudhri is relied on for the proposition that, Ahn’s graphic shadow is “[i]ndeed” a movable image known to give a user a visual cue. Id. But no such “cue” is provided in Ahn by the graphical shadow alone, because there is no movement of that object. The Petition does not present argument that a Chaudhri object is the movable object or how any of Chaudhri’s teachings of movable objects would have suggested to modify Ahn “to thereby move” the graphical shadow.” slip op. at 18

“the theory that Ahn’s graphic shadow moves. Reply 3−4. Petitioner interprets the sentences in Ahn we have analyzed above in conjunction with testimony of Dr. Terveen to argue that temporal descriptions in Ahn make it obvious for a person of ordinary skill in the art to drag in the right direction while continuing to press the graphic 1800. Id. (citing Exs. 1004 ¶¶ 117−119, Ex. 1023 ¶ 10). The Petition, however, relies on an Ahn disclosing a moving graphic shadow according to the embodiment of Figure 18(a), as described in paragraph 118. Petitioner now changes its theory of how Ahn’s graphic shadow would move according to paragraph 119, i.e., that although the graphic shadow is merely pressed (in the embodiment shown in Figure 18(b)) it would also be dragged while pressed. Reply 3. Not only is this a shift from the theory Petitioner presents in the Petition, it is not persuasive. As Patent Owner argues, and we agree, there is no cogent explanation for modifying the graphic shadow embodiment of Figure 18(b), especially in light of Ahn’s disclosure that the graphic shadow disappears when pressed and the menu list is displayed as emerging. Sur-reply 2−3. In other words, Petitioner’s new argument does not account for Ahn’s teaching that the objective of the graphic shadow is merely to notify the user of the start of the gesture, and once that start of the gesture is detected (the press on the graphic shadow), paragraph 119 informs us that there is no longer a need for the graphic shadow—it disappears from the display. Ex. 1004 ¶ 119. The Petition does not offer any argument for a theory in which the gesture of paragraph 119 (the press, not a touch and drag operation) results in graphic 1800 disappearing, while also moving during the disappearance. We are mindful that “[i]t is impermissible within the framework of section 103 to pick and choose from any one reference only so much of it as will support a given position to the exclusion of other parts necessary to the full appreciation of what such reference fairly suggests to one skilled in the art.” Bausch & Lomb, Inc. v. Barnes-Hind / Hydrocurve, Inc., 796 F.2d 443, 448 (Fed. Cir. 1986)). Consequently, we determine that Petitioner’s argument in Reply belatedly relying on the different embodiment of paragraph 119 is improper new argument, and that even if considered it is not persuasive.” slip op. at 20

“obviousness of the menus in the Ahn-Chaudhri combination following a user’s finger as the user performs the dragging gesture to open the menu.” Pet. Reply 2 (citing 01119-Petition, 26–33, substantially identical to Pet. 32– 40). However, again, the Petition does not explain an alternative theory in which Chaudhri supplements Ahn’s menu functionality to move that menu onto the screen, as opposed to teaching visual cues provided by gradual changes of the display during a gesture or the visual cue that an unlock image may provide during the unlock gesture. See Pet. 14–18 (describing Chaudhri teaching “visual differentiation” or “transitioning an optical intensity” between a user-interface object and the background, based on, e.g., transparency), 35–40 (same). In Reply, Petitioner adds evidence to attempt to support its contention that the combination teaches a menu following a user’s finger during a dragging gesture, involving references to Chaudhri’s discussion of a visual cue, further discussing Chaudhri’s unlock image. Ex. 1005 ¶¶ 54, 62, 74–79, Figs. 5A-5C (cited at Pet. Reply 4–5). With respect to these citations and arguments, even if they had been timely presented in the Petition, we agree with Patent Owner that they do not articulate a modification of Ahn with Chaudhri or a motivation to combine. PO Sur-reply 6. Additionally, we agree that these embodiments of Chaudhri are distinct from the cited portions of Chaudhri discussed with respect to this theory in the Petition, which relate not to the movement of displayed graphics, but to variations of optical intensity and visual cues. Id. at 6–7. We evaluate the Petition’s arguments in light of Petitioner’s statement in Reply that they require a teaching regarding “menus . . . following a user’s finger as the user performs the dragging gesture.” Pet. Reply 2. To the extent that the Petition shows that the combination of Ahn and Chaudhri would show visual changes as the user performs a dragging gesture, these do not relate to the movement of a menu, but rather to other optical effects. Thus, as we do not find that the Petition supports an Ahn-Chaudhri combination in which a menu follows a user’s finger as the user performs the dragging gesture to open the menu, as Petitioner argues, we determine that Petitioner has not shown limitation 2.d of claim 2 taught or suggested by the combination of Ahn and Chaudhri according to this theory.” slip op. at 31

“Petitioner argues that “even under [this] interpretation of Ahn, the only difference between Ahn and the claims is whether the animation occurs in direct correspondence with a user’s dragging gesture or after the dragging gesture is complete – a straightforward design choice if ever there was one.” Pet. Reply 3–4 (citing Ex. 1024, 99:16–108:20; Ex. 1023 ¶ 12). However, as Patent Owner argues (PO Sur-reply 7–8) this argument is presented in Reply and is an improper shift of theory from the Petition. Nevertheless, were we to consider it, we would not find it compelling; Dr. Terveen’s cited testimony repeats this bare statement and is not supported by any evidence or additional explanation.
