“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. Acceleron, LLC, 884 F.3d 1364, 1369 (Fed.

Even if we were to consider this new argument, it would not be persuasive. As Patent Owner observes (PO Resp. 20), any processing performed by peripheral device 32 in paragraph 321 is on data received from the processing device and destined for the base station via the network, rather than data flowing in the direction of the first processed video data of claim 1.” slip op. at 22

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.

“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

“a) Whether Dr. Almeroth’s Testimony should Be Given Little Weight Patent Owner argues that we should give little weigh to the testimony of Dr. Almeroth because Dr. Almeroth’s testimony is allegedly inconsistent across the related inter partes reviews. PO Resp. 11–16; PO Sur-reply 21– 22. We have reviewed the disputed portions of Dr. Almeroth’s testimony and, when read in context, we are not persuaded that the testimony is inconsistent so as to be afforded little weight. As Petitioner points out (Pet. Reply 2), Patent Owner’s arguments do not properly account for the context in which the testimony was given in the related inter partes reviews.” slip op. at 16

“Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the Deutschland Gmbh v.

Patent Owner agrees with Petitioner’s expert regarding the level of ordinary skill in the art. RMTA 19. Patent Owner’s declarant, Dr. Villasenor, notes that “obviousness must be viewed from the perspective of one of ordinary skill in the field of information security using cryptographic keys for encryption and decryption of digital data, and my opinions are rendered on the basis of the definition of the ordinary artisan set forth in the Petition in view of that further clarification.” Ex. 2010 ¶ 19.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“Patent Owner argues that there was no motivation to combine Peterka with Suzuki because Petitioner has argued that “Peterka can already identify content keys by using the allegedly unique sequence numbers or time stamps assigned to each message carrying a single content key.” PO Resp. 41–42 (citing Pet. 25). Patent Owner also challenges motivation to combine Suzuki because it “is not directed to a pay-by-time, pay-per-view, or subscription distribution model, in which a content key grants access to content that different clients must individually decide to purchase in discrete units or increments.” Id. at 36–37. Petitioner responds that, because Peterka disclosed alternative embodiments that did not use sequence numbers or time stamps to identify EMM/ECM messages, one of ordinary skill would have been motivated specifically assign identifications to individual keys as taught in Suzuki. Reply 22 (citing Pet. 26). Petitioner also argues that whether Suzuki was directed to unpurchased content was irrelevant, because Suzuki is cited to show multiple key responses were conventional. Id. at 19–20. Patent Owner does not otherwise specifically address the issue of motivation to combine Peterka, Suzuki, and Bocharov. See generally PO Resp. Nonetheless the burden remains on Petitioner to demonstrate unpatentability. See Dynamic Drinkware, 800 F.3d at 1378. We find, based on the record, that Petitioner has proved by a preponderance of the evidence that a person of ordinary skill in the art would have had reason to combine the teachings of Peterka, Suzuki, and Bocharov as proffered by Petitioner with a reasonable expectation of success.” slip op. at 45
- ScopeMotion to amend, deniedDenied
“We agree with Petitioner that the substitute claims are broadening. Because the amended wording only requires the key request to be made “in response to detecting” the boundary, rather than “ahead of” the boundary, the request can occur before or after the boundary. This is not a fanciful or unlikely possibility — such delayed requests are specifically contemplated by the ’178 patent: [I]f the packager 104 is unable to obtain a new content encryption key from the WFM 102 prior to the expiration of the current content encryption key, the packager 104 will continue to use the current content encryption key until such time as it is able to obtain a new key from the WFM 102. Ex. 1001, 6:32–37. It should be noted that the fixed period duration for key rotation may be viewed as a "target" period, as the packager 104 may not expire a key on the exact boundary. Ex. 1001, 8:9–11. The key expiration time from the WFM 102 may be viewed as a "suggested" expiration time, as the packager 104 may not be able to expire the key at the exact specified time.” slip op. at 56
