Petitioner makes additional contentions about what a POSITA would have understood. Id. (“A POSITA would understand that all types of cameras (e.g., analog and digital, photo and video) generally involve the same lighting considerations . . . .

Patent Owner contends that a POSITA would have at least: (a) a bachelor’s degree in electrical engineering, optical engineering, or a related field; (b) two years of practical experience in designing and developing lighting systems, particularly those integrated with electronic devices such as webcams or computer monitors; and (c) knowledge of user-interface considerations for consumer electronics . . . . Additional experience can substitute for education and vice versa. Prelim. Resp. 12 (citing Ex. 2036 ¶ 48).

The game processor also controls output signals to update the game process when appropriate. In addition, the game processor controls the redemption system of the present invention by calculating when prizes are awarded, calculating and updating prize lists and prize costs, and other functions, as described below. Ex. 1005, 9:18–27. As to the redemption system, Kelly discloses prize table 480 that is displayed to the operator. Ex. 1005, 34:64–65, Fig. 9a. In one embodiment, the operator can adjust prize characteristics for the game unit and any linked game units. Id. at 35:1–2. Kelly also discloses an alternative embodiment, however, in which selection of a specific prize from the table 480 can be based on random and/or statistical determination. Id. at 36:48–49. In this alternative embodiment, “random determination of whether a particular prize is to be awarded is also modified by statistical information to create a ‘best fit’ of prizes awarded according to the operator’s desired odds.” Id. at 36:63–66. awarded every 8,000 games, so if it is randomly determined that a third video console is to be awarded within, for example, the 3000th game, then a different prize, e.g., the next most valuable prize, can be awarded so that the desired odds are better met. Id. at 37:1–9. Thus, we find Petitioner has set forth sufficient evidence to show a reasonable likelihood that Kelly’s game processor can modify the variable parameters of the prizing structure to meet the mandated parameters of the desired odds, as called for in limitation [1.c.v].” slip op. at 23

“To remove Walker as prior art under §§ 102(a) and 102(e), Patent Owner must show either it reduced the invention to practice prior to Walker’s effective date, or that it invented prior to Walker’s effective date. In the case of the latter, Patent Owner must demonstrate conception prior to May 1, 2003, and reasonably continuous diligence throughout the entire critical period, which begins just prior to the Walker’s effective date and ends on the date of the invention’s actual or constructive reduction to practice. Patent Owner provides evidence purporting to show that it conceived of the invention prior to May 1, 2003. Patent Owner has not asserted that this evidence demonstrates actual reduction to practice, nor do we have sufficient evidence at this stage to make that determination. Further, Patent Owner’s earliest possible constructive reduction to practice (September 1, 2004) does not pre-date Walker’s effective date. Thus, at this stage, Patent Owner would need to show it invented prior to Walker’s effective date through evidence of conception and reasonable diligence to remove Walker as prior art. At this stage of the proceeding, without Patent Owner’s evidence of diligence, Patent Owner has not provided sufficient evidence to show that Petitioner fails to show a reasonable likelihood of prevailing in establishing that Walker is prior art. This issue of whether Walker is prior art to the ’164 patent will benefit from further development of the record during the trial proceeding.” slip op. at 31

“But the Detecting Limitations of claims 1, 19, and 20, merely require that a target be “detected.” The Detecting Limitations do not require that target detection be performed “aboard the reference UAV,” and claim 19 does not recite or require “machine learning.” Moreover, the Specification makes clear that the claims should not be limited to aspects of the disclosed embodiments, as Patent Owner proposes to do here. See, e.g., Ex. 1001, 2:56–59 (“The invention is described in connection with such embodiments, but the invention is not limited to any embodiment. The scope of the invention is limited only by the claims . . . .”) Patent Owner additionally fails to cite any lexicographic definition or clear and unambiguous disclaimer of claim scope sufficient to limit the claims in the manner it proposes.

“permission module,” as used in claim 1, has “a well understood structural meaning in the computer technology field.” 792 F.3d at 1350. Rather, the limitation in question is “drafted in the same format as a traditional means-plus-function limitation, and merely replaces the term ‘means’ with ‘nonce’ word ‘module,’ thereby connoting a generic ‘black box’ for performing the recited computer-implemented functions.” Id. And, while claim 1 recites the “outputs” of the permission module (i.e., a determination regarding the permissions of an aerial system), “the claim does not describe how the [permission module] interacts with other components in the [discrimination system] in a way that might inform the structural character of the limitation- in-question or otherwise impart structure to the [permission module] as recited in the claim.” Id. at 1351. We also reviewed the Specification, and we agree with Petitioner that the Specification identifies the following structure as corresponding to the claimed permission module: “storage on-board the disruption module 105, storage on-board the identification receiver 102, a remote computing system connected to the disruption module…, or [] any other suitable computing system.” See Pet. 12; Ex. 1001, 9:64–10:4. slip op. at 7
