“On this record, we find Petitioner’s contentions persuasive. As noted above, Lee states the following: “[I]f the coloring disable bit indicates that the frame corresponds to a trigger frame related to multiuser transmission, the STA may not perform the change of the CCA level irrespective of information indicated by the coloring bit.” Ex. 1005 ¶ 68. Even though the coloring disable bit indicates that the frame corresponds to a trigger frame for multiuser transmission, Lee states that “the coloring disable bit can also be comprehended as a bit indicating that CCA level change is not performed.” Ex. 1005 ¶ 68. This supports Petitioner’s contention that the coloring disable bit is signaling information that indicates that a CCA level change is not allowed, even if it indicates other things as well.

“To the extent Patent Owner contends that a person of ordinary skill in the art need not be defined as of the critical date, we disagree. Under Section 103, we must determine “if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains” (emphasis added). “Obviousness is determined from the vantage point of a hypothetical person having ordinary skill in the art to which the patent pertains.” In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). Thus, we define the hypothetical person of ordinary skill in the art as of a time before the effective filing date. To the extent Patent Owner’s argument is that, to testify from the perspective of a person of ordinary skill in the art, one need not have been a person of ordinary skill in the art as of the critical date, we agree. Although one must at least possess ordinary skill in the art to testify from the perspective of a person of ordinary skill, time of the invention to be able to testify from the vantage point of a person of ordinary skill in the art. Rather, an expert can acquire the necessary skill level later and develop an understanding of what a person of ordinary skill knew at the time of the invention.” slip op. at 5

“On this record, it is not entirely clear that comparing a BSS color value to determine if a receiving station is in that BSS is prohibited by the claim’s recitation “not to use” a BSS color, as Patent Owner’s argument implies. Rather, claim 1’s recitation “not to use a Basic Service Set (BSS) color when signaling information indicates that an operation based on the BSS color is not allowed” appears directed to prohibiting a particular operation based on the BSS color, not necessarily disregarding the BSS color entirely. Further, comparing BSS values to determine BSS identity appears consistent with claim 1’s recitation that “the BSS color is an communication terminal recognizes that a BSS color collision has occurred.” On this record, it appears that BSS color would need to be identified to determine if a color collision occurs. See Prelim. Resp. 4 (“BSS color collisions occur when two or more BSSs operating on the same frequency channel (and overlapping in coverage area) use the same BSS color. See ’163 Patent at 2:46-59, 10:41-62. In other words, a wireless communication terminal receives a signal with the same BSS color that device understands applies to it, even though the signal is intended for another device in a different BSS (albeit using the same BSS color). When a color collision is detected, the wireless communication terminal reports to the base wireless communication terminal, which will indicate that a color collision has occurred. ’163 Patent at 3:16-20.”). In that light, we see some merit in Petitioner’s position that an “operation based on BSS COLOR (e.g., allowing access and re-using the channel) is not allowed” based on the Low Power/High Interference Indicator, even if some reference is made to the BSS color to resolve a condition precedent to that determination, namely whether the data are from a different BSS. See Pet. 53–54 (citing Ex. 1009 ¶ 26; Ex. 1003 ¶ 170). Petitioner’s second theory is based on setting the color field to a reserved value of “0000,” which Petitioner argues “indicates that operations based on BSS COLOR are not allowed and the receiving STA does not use BSS COLOR.” Pet. 54–55 (citing Ex. 1009 ¶¶ 25, 29; Ex. 1003 ¶ 172). On this record, we question how setting a color value to 0000 can teach the subject matter of claim 1, which also requires that “the BSS color is an identifier of a BSS.” Petitioner acknowledges that a reserved value of 0000 in the color field does not identify a BSS. See Pet. 54–55 (asserting that a that a COLOR field value of ‘0000’ does not represent a valid BSS identifier”). We also recognize, however, that claim 7, depending from claim 1, recites “the BSS color indicated by the signaling field of the PPDU is a predetermined value” and that claim 8, depending from claim 7, recites that the predetermined value is 0. Thus, Choudhury’s reserved value disclosures appear to teach this subject matter of claims 7 and 8, even if claims 7 and 8 are inconsistent with claim 1’s requirement that “the BSS color is an identifier of a BSS.” See Ex. 1001, 21:23–30 (disclosing that the BSS color value may be set to a predetermined value such as zero).” slip op. at 12

Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)).

Instead, the language in the prosecution history is consistent with the ordinary and customary meaning. That is, the applicant focuses on the location of the object relative to the area of game play, i.e., the foreground. For example, the applicant distinguishes Chu’s object as not being “background objects” because they “are featured in the forefront of [the] game play as primary objects to be manipulated or used during game play (see Chu at ¶¶ [0063]–[0065]).” Ex. 1002, 85 (emphasis added).12 The applicant continued by arguing that Chu’s objects “exist in the background, outside of the primary focus of game play and as unexpectedly interactive components, and are not themselves needed or required in order to play the game.” Id.

“As an initial matter, Bharadwaj and Sun are both analogous art to the ’210 Patent in that that they are both concerned with the design of the PHY data unit for supporting MU-MIMO transmissions in the downlink. SAMSUNG-1003, ¶¶153- 158. . . . In addition, both Bharadwaj and Sun describe MU- MIMO downlink PHY data unit structures in the context of 802.11ax.

[A] POSITA implementing Bharadwaj’s preamble designs would have been motivated to look to another reference, like Sun, for an understanding of the format of the user field that would support non-MU-MIMO allocations and the single-user transmission scenario. A POSITA would have combined the teachings of Bharadwaj with Sun to realize implementation details for the HE-SIG-A and HE-SIG-B fields of the HE MU PPDU to better support both MU-MIMO and non-MU-MIMO allocations. SAMSUNG-1003, ¶¶153-158. . . . . A POSITA would have found it obvious to look to Sun for modifying Bharadwaj to include the user field format for SU (non-MU-MIMO) allocation to complement Bharadwaj’s disclosure of the MU-MIMO user field format and to provide a more complete system that would allow HE MU PPDUs to support both MU-MIMO allocations for multiple users and non-MU-MIMO allocations for a single user. SAMSUNG- 1003, ¶¶153-158. The combination also would have been obvious and predictable for at least the following reasons: 1) both Bharadwaj and Sun describe designs for a PHY data unit (or PPDU) to support communications between an AP and a station within a high-efficiency Wi-Fi network, consistent with 802.11ax; 2) both Bharadwaj and Sun describe the PPDU design for supporting MU-MIMO downlink transmission as including HE- SIG-A and HE-SIG-B fields; and 3) Bharadwaj already describes the format for the user field for the MU-MIMO allocation, while also recognizing the single-user scenario, and the combination merely involves the addition to Bharadwaj of the user field format for the single-user allocation, as taught by Sun. SAMSUNG-1003, ¶¶153- 158. The combination is obvious also because elements of the combined system would each perform similar functions they had been known to perform in similar contexts outside the combination. SAMSUNG-1003, ¶¶153-158. . . . . A POSITA would have reasonably expected success implementing the combination, especially considering the substantially similar 802.11ax techniques described in each reference.

“Hays discloses that an advertiser can target particular ads at particular times, such as “air[ing] the Domino’s ad campaign” after a “game has been played for 45 minutes.” Ex. 1005 ¶ 22. Thus, an advertiser selects ads to run, and those ads become part of the pool from which the advertising matching and weighting system selects ads. See Ex. 1005 ¶ 22 (“Based on information associated with each of the available ad units (e.g., current game environment, game title genre, predicted player demographic information for current available ad unit, player geography, time of day, etc.), the advertisement server may then (through matching and optimization) distribute and deliver targeted advertisements to players’ gaming devices, where the advertisements may be integrated into the relevant game areas in real time.” (emphasis added)). Thus, we agree with Petitioner that the ad targeting described in Hays’s paragraph 22 happens before the matching and weighting system determines which ads to serve. Pet. Reply 3–4 (referring to Hays’s paragraph 22 and arguing that the “pre-selection plainly happens serve to a particular mobile device”). In other words, ads are pre-selected before they are ultimately selected by the matching and weighting system. Petitioner’s contentions and Hays’s disclosures are consistent with the ’056 patent’s written description, which states the following: The pre-selected content may be stored on a storage medium accessible by the server. Updated content may be chosen from pre-selected content based on at least one of the factors including a type of the mobile communication device, a telecommunication service, a subscription associated with the mobile communication device, and a service provider of the telecommunication service. Ex. 1001, 11:34–40. Thus, the ’056 patent discloses that content is selected from pre-selected content. Claim 9 similarly requires identifying “what preselected in-game video game content to send,” meaning that content is selected from pre-selected content. See Tr. 31:2–5 (Patent Owner’s counsel’s argument that “there must be a pre-selection of certain content that will be available from which to select once the request is received, and then the checking step is performed in the various claims here”), 31:21–23 (Patent Owner’s counsel’s argument that “[t]here must be some pre-selection of, you know, kind of narrowed down content, if you will, but then when the request comes in, you choose among that pre-selected content for the final selection”). On this record, we find that Petitioner’s contentions and Hays’s disclosure of selecting ads to serve from a pool of ads that are selected ahead of time are consistent with the written description of the ’056 patent and show how Hays teaches the pertinent claim limitations.” slip op. at 22

“Owner’s position to be that mere storage of content is not enough to show pre-selection of that content. For example, during oral argument, Patent Owner’s counsel argued as follows: I don’t think it’s just as simple as saying, well, anytime you store anything, it’s been pre-selected, because again, that kind of reads out pre-selection, as well. And the same thing with indexing. I think that’s simply too broad. There must be some pre-selection of, you know, kind of narrowed down content, if you will, but then when the request comes in, you choose among that pre-selected content for the final selection.

“The claim language itself suggests no such restrictions. Rather, the claim language simply recites video-game content that is usable in the video game. The claim language does not specify who or what must use the content or how it must be used. Thus, the claim language itself is broad and includes none of the restrictions Patent Owner would place on it. As Petitioner points out (Reply 5), the specification directly refutes Patent Owner’s position. The ’202 patent’s Figure 2A (reproduced above) is instructive. In this example, “several items 210, 220, 225, 230, and 235 are shown within scene 200,” and virtually any of these items may be changed by receiving updated content on the mobile communication device. For instance, the shirt 230 might be updated to include a logo associated with third party X (as shown). The poster 225 might advertise an upcoming movie for third party Y, and chalk board 220 may contain a handwritten advertisement for third party Z (as shown). Ex. 1001, 6:42–50. When an advertising contract changes, “the mobile communication device may thereafter download updated content reflecting a new graphic, shirt, or entirely new object, to place at 230.” Id. at 6:55–57. These are examples of updated video-game content (updated advertisements on posters, T-shirts, and chalk boards) that are usable (e.g., by the game or mobile communication device executing the game) in a video game that already exists on the mobile communication device. These are also examples of what Patent Owner argues are “skins” that correspond to existing ad units and that do not alter any function of the game. Patent Owner’s construction, then, would exclude the ’202 patent’s preferred embodiment. “Such an interpretation is rarely, if ever, correct and would require highly persuasive evidentiary support, which is wholly absent in this” slip op. at 12

Petitioner relies upon Lemoff for a suggestion to combine Lemoff’s fiber connector configuration teachings with Kurita’s multiplexer teachings to enable fibers to be plugged Fig. 2) (Pet 29, 31; Reply 17–18). Regarding Patent Owner’s argument that one of ordinary skill in the art would not have combined Lemoff’s receptacle and ferrule with discrete components in Kurita because the fiber would need to be manually fixed and aligned with or without a ferrule and, therefore, would serve no purpose (PO Resp. 48), Lemoff’s fiber connector appears to fix and align the fiber adequately for wavelength division multiplexing without manual fixation or alignment being required (Ex. 1006, 5:65–6:2, Fig. 2; Reply 18). The challenged claims do not require any greater degree of fixing and alignment than that provided by Lemoff’s fiber connector. Regarding Patent Owner argument that Lemoff’s device is not physically combinable with Kurita’s WDM multiplexer due to Lemoff’s device’s small size (PO Resp. 47–48; Reply 17–18), “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference....

Claim 1 requires “focusing means having n separate radial sectors on its surface, and each of said n collimated beams passes through a separate one of said n sectors of said focusing means” (Ex. 1001, 5:34–37), claim 2 requires “four lasers and four collimating lenses are each formed in a two-dimensional, two by two array [centered on the focal axis of lens 30], wherein said focusing means is a single focusing lens, and wherein each radial sector is a pie-shaped quadrant” (id. at 5:41–44), and claim 7 requires “focusing means having four separate quadrants on its surface, and each of said four collimated beams passes through a separate one of said quadrants of said focusing means” (id. at 6:35–38).
