    “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged.

Cir. 2006). “Instead, the benefits, both lost and gained, should be weighed against one another.” Id. (quoting Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000)). Based on the record presented, there appear to be advantages to cradle integration as well as advantages to using a standalone cradle. Assessing all of the evidence presented, though, we are persuaded that a person of ordinary skill in the art would have been motivated to integrate the cradle into the computer of the combined Denison-Roatis system, as Petitioner contends. Most importantly, Deguchi discloses that various devices of the time required a cradle for communication between a portable device and host device and then expressly states that it would have been “desirable” instead to provide for a “direct connection” between a portable device and host device “for data exchange and storage without the need for an intermediary type connection such as a cradle.” Ex. 1004 ¶¶ 4–14. Both Denison and Roatis disclose communication between a host device (computer) and portable device (electronic key) for data exchange and storage. Further, all three references disclose wireless communication with a portable device. See Ex. 1002 ¶¶ 41, 77, 85; Ex. 1003 ¶¶ 69, 129, claim 2; Ex. 1004 ¶¶ 39–42. Thus, a person of ordinary skill in the art, having all three references available, would have understood that it would have been desirable to have a direct connection between the electronic key and computer, rather than using a cradle as an intermediary between the two. We credit the opinion of Mr. Allison (who is the only declarant to provide testimony on issues concerning patentability in this proceeding) that a person of ordinary skill in the art would have been motivated to integrate the cradle into the computer of the combined Denison-Roatis system. See Ex. 1013 ¶¶ 117–120. Mr. Allison’s testimony is consistent with the references themselves. See id. ¶¶ 114–122. He also testified as to the known problems with cradles, which integration with the computer would avoid. See Ex. 2002, 33:18–34:1 (“There’s a lot of trade-offs with cradles. Any accessory adds one more thing to carry around, one more thing to break, where you might place it, those kind of things.”).” slip op. at 32
