“We do not agree that the references relied upon in the Petition are cumulative of the Banerjee and Epstein references previously considered by the Office. For example, during reexamination Patent Owner represented to the Office that neither Banerjee nor Epstein discloses or suggests “an actuator on the peripheral device, wherein said actuator is arranged in a way to enable the user to carry out a user action by actuating the actuator to trigger the processing device to transfer said user selected arbitrary media content to said wireless transmitter through said port to transmit said user selected arbitrary media content to the display node via the communications network” . . . .

Ex. 2001, 124–125 (emphasis added). Here, however, Petitioner relies primarily on the structures and operations disclosed by Ono, Ichieda, and Uchida to demonstrate it would have been known to include an actuator on a wireless peripheral device to trigger the transfer of a user selected arbitrary media content. See Pet. 31–33, 57–59, 77. Importantly, unlike Epstein or Banerjee, each of those references discloses display systems that include wireless peripheral devices that have actuators that are at least related to facilitating the transfer of image data from a personal computer to a projector for display. See id. As such, we find that Ono, Ichieda, and Uchida present information that is neither substantively similar nor cumulative of that disclosed or suggested by Banerjee and Epstein.

“Patent Owner’s assertion fails to undermine Petitioner’s contention because it does not actually address Petitioner’s point, which is that a skilled artisan would recognize, when a user slides switch 140 back to the ‘OFF’ position to allow image transfer to resume, that action would trigger image data transmission of user selected arbitrary media content from wireless through the wireless communications network for display. Instead, Patent Owner’s argument only addresses when a user slides switch 140 to the “ON” position to stop image transmission. On this record, we determine that Petitioner’s evidence and analysis shows sufficiently that Uchida and Grimshaw disclose this last claim element of claim 1. 4. Conclusion After considering Petitioner’s evidence and argument, we determine the information presented shows a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of claim 1 based on the combination of Uchida and Grimshaw (Ground 2). We also note that both parties rely on substantially the same evidence and arguments to address independent claims 9, 16, and 21. See Pet. 49–59 (claim 9), 64–66 (claim 16), 67 (claim 21); Prelim.

The caveat is that, although step [a] must be performed before step [b], it is within the scope of claim 1 if step [a] continues to be performed even after step [b] begins. Tr. 25:25–26:3 (Mr. Engel: “Well, I think in practicality, there would always be monitoring because there’s multiple media streams. So, you could have multiple alerts come in and the system could decide which one is more important. So, I don’t think you stop monitoring per se.”).

That said, the Board recognizes that there may be circumstances in which more than one petition may be necessary, including, for example, when the patent owner has asserted a large number of claims in litigation or when there is a dispute about priority date requiring arguments under multiple prior art references. In such cases two petitions by a petitioner may be needed, although this should be rare. Id.

“depends, recites “[a]n output buffer circuit for outputting data in the form of an input pulse train at a predetermined output impedance and slew rate.” Because Patent Owner contends that the asserted prior art fails to teach outputting data “at a predetermined output impedance” as recited in the preamble (PO Resp. 16), we first determine whether the term “at a predetermined output impedance” is limiting. “In general, a preamble limits the invention if it recites essential structure or steps, or if it is ‘necessary to give life, meaning, and vitality’ to the claim.” Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (citation omitted). “Further, when reciting additional structure or steps underscored as important by the specification, the preamble may operate as a claim limitation.” Id. “Conversely, a preamble is not limiting ‘where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.’” Id. (citation omitted).” slip op. at 10

“parlance carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising.’”)). “Predetermine” simply means “to determine beforehand.” Predetermine, MERRIAM-WEBSTER DICTIONARY, available at https://www.merriam-webster.com/dictionary/predetermine. As Petitioner observes, we typically understand “a” to mean “one or more.” See KCJ, 223 F.3d at 1356. Thus, the ordinary meaning of “a predetermined output impedance” is one or more output impedances determined in advance. Patent Owner does not point to any claim language to support its argument that a predetermined output impedance is limited to a single output impedance. As explained in more detail below, the specification does not redefine “a predetermined output impedance” to mean a single output impedance or exclude or disavow multiple output impedances from among those that can be determined in advance.” slip op. at 18

“second n-channel MOS transistor have a smaller device size with a smaller gate width than said first p-channel MOS transistor and said first n-channel MOS transistor.” In the Institution Decision, we preliminarily construed “smaller device size” and “smaller gate width” to be synonymous, rather than two separate requirements. Dec. 11–13. Patent Owner acknowledges the understanding set forth in the Board’s Institution Decision, and accepts that the proper comparison is between the combined device size of the P2, N2 pair with the device size of the combined device size of the P1, N1 pair. In other words, if the device size of P2 is less than the device size of P1, and the device size of N2 is less than the device size of N1, then the size requirements of claim 4 are satisfied. PO Resp. 16. Thus, it appears that Patent Owner does not contest our construction or propose an alternative. On the complete record, and for the reasons set forth in our Institution Decision, we maintain our construction of “smaller device size” and “smaller gate width” as synonymous.” slip op. at 22

“B. Claim Construction We construe a claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. [§] 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” 37 C.F.R. § 42.100(b); see also Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). Petitioner contends that “no claim elements need a formal construction for purposes of resolving controversies in this proceeding.” Pet. 5. Based on the record before us, we do not find it necessary to provide express claim constructions of any claim terms. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

“Zhang, in light of Zill’s suggestion, to generate wakeup packets at Zhang’s server 404 rather than at end user 406. Pet. 36 (citing Ex. 1004 ¶¶ 61, 62; Ex. 1003 ¶¶ 112–119). Petitioner contends that doing so would have allowed Zhang to accommodate more types of requesting computers, including legacy hosts that might not have the software or hardware to securely process Zhang’s query replies and generate wakeup messages. Id. at 36–37 (citing Ex. 1004 ¶¶ 61, 62, 64, 65, 77; Ex. 1005 ¶ 111; Ex. 1003 ¶ 113). Petitioner also argues that generating the wakeup messages at the server would improve security, as servers would have been able to operate better security features. Id. at 37 (citing Ex. 1004 ¶ 36; Ex. 1005 ¶¶ 40, 111; Ex. 1003 ¶¶ 114–115). Petitioner further argues that generating wakeup messages at the server would have reduced the quantity of messages exchanged containing sensitive information, reducing the risk of interception by a malicious actor. Id. at 37–38 (citing Ex. 1003 ¶ 116). Petitioner further argues that it would have been more efficient to generate the wakeup message at the server, as Zill suggests, as the server can include optimized hardware. Id. at 38 (citing Ex. 1003 ¶ 117). According to Petitioner, the combination would only require combining familiar elements according to known methods, to yield predictable results, and that a skilled artisan would have a reasonable expectation of success doing so. Id. at 38–39 (citing Ex. 1003 ¶¶ 118–119). Patent Owner does not yet contest these allegations. Upon consideration of Petitioner’s evidence, including Mr. Kardashov’s testimony, we are persuaded that Petitioner shows sufficiently that a skilled artisan would have had reasons, with rational underpinning, to combine the teachings of Zhang and Zill.” slip op. at 21
