“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

“5 At the oral argument, when challenged on its reliance on paragraph 322, Petitioner argued that paragraph 321 of Beel teaches this limitation. Tr. 22:26–23:24. Petitioner did not make this argument in the Petition and, instead, raised it for the first time during oral argument; thus, it will not be considered. See Dell Inc. v.

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

“1. “closed loop” The term “closed loop” is recited in each independent claim. Petitioner asserts that in the Delaware action , the district court construed “closed loop” as “gas pathway within a display housing containing gas that is essentially isolated from external air.” Pet. 11 (citing Ex. 1026, 1). Petitioner asserts that the district court’s construction is the proper construction, in light of the specification and the prosecution history of the ’740 patent. Id. at 11–12. Petitioner explains: The ’740 patent refers to the gas/air, circulating through a closed loop as the circulating gas/air and also as the “isolated gas.” (Ex. 1001, 9:64–10:3, 10:7–9, 10:56–58, 11:30–12:6 (claims reciting circulating gas/air), 3:30–[39], 3:50–52 (specification referring to gas in the closed loop as “circulating gas” and “isolated gas”), FIG. 1.) Moreover, as noted above, the Applicant distinguished the claims from the Thielemans prior art based on the argument that the closed loop must be separate from and in addition to the open loop. (Ex. [1031], pp. 44-45, 160 (Responses filed on 01/07/2019 and 08/15/2019).) The Court’s “closed loop” construction should apply here, though Applicant notes that this claim construction does not affect the applicability of the prior art in this Petition because the art teaches the separate loops. Id. at 12. Petitioner’s characterization of the prosecution history with respect to the Thielemans reference is inaccurate. Our review of the cited portions of the prosecution history reveals that the Applicants did not argue to the Examiner that the closed loop and the open loop must be isolated from each other and cannot mix. Rather, the Applicants argued that Thielemans discloses having an open loop or a closed loop, not both an open loop and a closed loop. Ex. 1031, 44–45, 160. The Applicants also argued that Thielemans’s closed loop is not “about” and is not “encircling” the electronic image assembly. Id. at 160.

“legally sufficient motivation for modifying Paulraj, but only attempted to show that the modification “could” have been made by one of ordinary skill in the art which is not enough for a showing of obviousness. Sur-reply 8–9. We disagree with Patent Owner. Establishing that certain technique was well-known to one of ordinary skill in the art at the effective filing date of the challenged patent constitutes sufficient motivation to make a modification in accordance with what was well-known in the art to one of ordinary skill, absent factors not present here. Indeed, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. That would be the situation where a technique was well-known to one of ordinary skill in the art, unless there is actual difficulty in making the application. The “improvement” here, although not articulated by Petitioner, is inherent with the technique, not requiring use of separate antennas for transmitting and receiving, i.e., eliminating the need for additional parts. Further, it is not necessary to show that a modification is the “best option,” because any “suitable option” would suffice. See Intel Corporation v. Qualcomm Incorporated, 21 F.4th 784, 800 (Fed. Cir. 2021). Here, Patent Owner does not assert that one of ordinary skill in the art would have had difficulty modifying Paulraj to use some of the same antennas both for transmitting and for receiving. Nor does Patent Owner dispute that it was well known to one of ordinary skill in the art to use the same antenna(s) for both transmitting and for receiving. We further note the following description in the Specification of the ’083 patent: “The typical CT/MD [cellular telephone/mobile device] has one transmitter and one receiver (T/R), with one antenna.” Ex. 1001, 1:47–48. That statement is fully consistent with Petitioner’s assertion that it was well-known to use the same antenna for transmitting and for receiving. For the foregoing reasons, notwithstanding Patent Owner’s arguments to the contrary, we determine that Petitioner sufficiently has shown that it would have been obvious to one of ordinary skill in the art to modify Paulraj such that some of the same antennas would be used both for transmitting and for receiving, according to limitations 1[b], 1[d], and 1[e].” slip op. at 36

“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.

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.

“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

Nor does Petitioner respond to our inquiry about whether collateral estoppel maybe applied on a limitation by limitation basis. See Pet. Reply 27. At the hearing, however, Petitioner confirmed that resolution of the issue is not necessary to our final determination. JUDGE ROSS: Do we even need to decide the collateral estoppel issue? I mean, it seems to me that if your petition clearly made out your case for the combination of Richardson and Zhao, then we don't even need to reach that. MR. CHANDRA: That’s exactly right, Your Honor. That is our position, as well. We believe collateral estoppel applies, but you don't need to decide that issue in order to find these claims unpatentable. As I mentioned before, these are the same references. We have fairly sought out all of the portions of Richardson, we cited to specific portions. Not just relying on collateral estoppel, but the teachings of the reference itself. So, while this is an issue, we believe that collateral estoppel should apply. It does not have to apply in order to find the challenged claims unpatentable. Tr. 19:9–20. We are persuaded, as discussed in Section II.G., that Petitioner has shown where Richardson in combination with Zhao meets each limitation of the claims of the ’203 patent. Accordingly, we need not address whether Petitioner has demonstrated sufficiently that collateral estoppel applies here.” slip op. at 14
