Neither party presents any arguments relating or referring to the level of ordinary skill in the art.

Specifically, Kim explains that, “[i]f detecting a user gesture, namely, if receiving an input event from a user through the touch screen, the mobile device determines the type of an input event.” APPLE-1004, [0053].

In response, the blades of grass 105 displayed in the area of the screen swiped by the user are caused to bend or sway as if contacted by the user’s finger during the swipe.” Ex. 1004 ¶ 28. Because this description expressly refers to “swiping” or moving the finger “across” the display screen, it does not encompass a mere tap, or contact by the user that does not move on the display screen. If a single-tap-contact embodiment for moving the blades of grass in the background wallpaper is disclosed, it would be in an embodiment different from the swiping embodiment. Here, Petitioner is relying only on the swiping embodiment for moving the blades of grass in the background wallpaper. Thus, we disagree with Patent Owner that Hackborn discloses no need to distinguish a tap from a swipe. We find that in the swipe embodiment, it is important to distinguish a tap from a swipe, and thus there is reason, as Petitioner contends, for one of ordinary skill in the art to look to Westerman for implementation details on how to make such a distinction. Specifically, for recognizing a swipe from a tap, Westerman describes determining whether the finger path displacement exceeds a predetermined threshold (Ex. 1005 ¶¶ 19, 61), and examining the initial velocity of the contact at contact’s touchdown (Ex. 1005 ¶¶ 19, 62). As for Patent Owner’s noting that in several instances Hackborn generally refers to a user’s finger contacting items on the wallpaper, that does not undermine Petitioner’s positions, because in the “swipe” embodiment, the referenced contact would be a swipe, and not a single tap without any motion of the finger.” slip op. at 17

    “Pet. 39. This reasoning is unpersuasive. The reference in claims 17, 37, and 38 to “the at least some of the plurality of images” identifies the at least some of the plurality of images first recited in claim 1 on which claim 17 depends, and the at least some of the plurality of images first recited in claim 23 on which claims 37 and 38 depend. According to independent claims 1 and 23, however, the displaying in sequence of the at least some of the plurality of images must be based in part on the magnitude of the first contact. Pet. vii–vii, xiv. The social networking posts and images contained therein images, identified by Petitioner as being displayed in sequence by automatically moving one-by-one, have not been shown by Petitioner as being displayed based in part of the magnitude of the user contact, as Patent Owner correctly notes. PO Resp. 32–35. In its Reply, Petitioner attempts to change its reasoning for claims 17, 37, and 38 by shifting to rely on the background wallpaper of grass swaying in response to user swiping. Reply 13–14. This shift in reliance is a belated new argument and not entitled to consideration. We decline to consider it. Accordingly, Petitioner has not proved by a preponderance of the evidence that claims 17, 37, and 38 would have been obvious over Hackborn and Westerman. E.” slip op. at 27

    “We agree with Petitioner. The evidence of record, including the ’892 patent and its prosecution history,9 indicates that the ordinary and customary meaning of “transitioning . . . from . . . to” encompasses both direct and indirect transitions. Looking first to the claim language itself, the word “directly” appears in claims 1, 6, and 10, but not claim 14, presumptively suggesting that claim 14 was intended to more broadly capture systems with either direct or indirect transitions. See CAE Screenplates Inc. v. Heinrich Fiedler GmbH, 224 F.3d 1308, 1317 (Fed. Cir. 2000) (“In the absence of any evidence to the contrary, we must presume that the use of . . . different terms in the claims connotes different meanings.”). Holding otherwise would fail to give any effect to the word “direct” as it appears in claims 1, 6, and 10. See Stumbo v. Eastman Outdoors, Inc., 508 F.3d 1358, 1362 (Fed. Cir. 2007) (denouncing claim constructions methodologies that render phrases in claims superfluous).” slip op. at 12

    “predictable and well-motivated variation of G.987.3, at the time of the claimed invention, to include a direct transition between the ONU’s two low-power states. See KSR v.

If a person of ordinary skill can implement a predictable variation, § 103 likely bars its patentability.”). We credit Dr. Sergienko’s testimony that a person of ordinary skill in the art would have been motivated to reduce power consumption and would have looked to ways of modifying G.987.3 to further that design goal. See Ex. 1003 ¶ 70; see also Ex. 1007, 97 (“For a variety of reasons, it is desirable to reduce the power consumed by an ONU as much as possible . . . .”). We also credit Dr. Sergienko’s testimony that there were only a small number of ways to modify the state transitions in G.987.3’s ONU, and that it would have been obvious to consider those possibilities. Ex. 1003 ¶ 70. Patent Owner does not contest this. Dr. Litvin concedes, for Patent Owner, that “there is no conceivable way the [ITU] did not consider the proposed transition” between the ONU’s two low-power states when drafting G.987.3, although he contends the standards body prohibited such direct transitions as “a conscious and reasoned design choice.” Ex. 2007 ¶ 108; see also id. ¶ 109 (opining that there were only four possible choices for transitions in the ONU, and the ITU “undoubtedly considered all of them, including the direct transition from . . . Listen and . . . Asleep”); PO Resp 24 (conceding that “G.987 explicitly considered the very direct transitions that Petitioner say would be used”). We also find persuasive Petitioner’s additional or alternative argument that Röger would have motivated modifying G.987.3 by allowing the ONU, while in sleep mode, to periodically turn on its receiver and check for messages from the OLT, which would have been direct transitions between “first” and “second” states as recited in claim 1. Pet. 20–22 & n.4; Ex. 1003 ¶¶ 82–84. The evidence suggests that modifying G.987 as Petitioner proposes would have been within the abilities of a person of the ordinary skill in the art at the time of the claimed invention—either to add a direct transition between Listen and Asleep states or to allow the ONU, while in its sleep (both transmitter and receiver off) mode, to periodically turn on its receiver temporarily to listen for polling messages from the OLT, as Röger teaches.

    “We do not reach a resolution on the issue of relative cost between a wired LAN versus a wireless LAN, because Petitioner’s assertion that wireless LANs “were often cheaper and easier to install” is nebulous by use of the imprecise word “often.” “Often” cheaper permits “often” not cheaper. Much depends on how many access points would exist in the wired LAN. Petitioner does not discuss that consideration in the context of Horn. Also, we are persuaded by Petitioner’s other stated reasons for implementing Horn’s LAN as a wireless LAN: (1) that a wireless LAN can be more convenient to users, and (2) Baumgartner provides adequate motivation by disclosing transmission of video from server 36 via communications network 34 such as the Internet over link 48 implemented wirelessly to user computer equipment 22 such as a personal computer. Pet. 29–32. We are persuaded that a wireless LAN provides more user convenience by enabling the user equipment accessing the external network to be flexibly located within the range of the LAN without need to have wires installed to run to those locations. That is true whether there is only one user equipment or there are multiple user equipment, one per user. In the case of only one user equipment, the user can access the external network from a wide range of locations and change that location flexibly. In the case of multiple user equipment, one per user, each user can access the external network from his or her own preferred location, and also change that preference at any time without regard to whether wires have been installed to the preferred location.” slip op. at 22
