    “Beel actually discloses the following: [0321] On the peripheral device 32 the video packets are received at the corresponding plug and play port, e.g. the USB port 11, read by the Human Interface Driver (HID) interface handler 13, unpacked to remove HID protocol headers in an unpacker 20 and then transmitted to the communications network by a transmitter 21. The network can be wireless for example WiFi or LiFi network. [0322] Having been routed over a communications network to the base unit 33, the incoming stream is read from the communications interface such as a WiFi access point 22, unpacked in an unpacker 25, decoded in a decoder 26 and then inserted into a suitable composition such as an OpenGL based composition in the compositor 29 for display on a central display device. Ex. 1005 ¶¶ 321–322 (emphasis added to portions quoted by Petitioner). Patent Owner notes that “[t]he Petition mistakenly cites to ¶ 322 of Beel but quotes ¶ 321.” PO Resp. 20 n.3. However, it appears that Petitioner has grafted together a portion of paragraph 321 that introduces peripheral device 32 with a portion of paragraph 322, which discusses features of base unit 33. However, this grafting has been done in such a way as to convey (incorrectly) that peripheral device 32, not base unit 33, includes unpacker 25, decoder 26, and compositor 29 that process the first processed video data received by the first peripheral device to generate second video data. Dr. Almeroth’s testimony, which copies Petitioner’s incorrectly altered quotation to paragraph 322 of Beel, is unreliable as to this claim limitation and is entitled to no weight.4 Thus, Petitioner has no expert testimony on which to rely for this claim limitation.” slip op. at 19

    “5 At the oral argument, when challenged on its reliance on paragraph 322, Petitioner argued that paragraph 321 of Beel teaches this limitation. Tr. 22:26–23:24. Petitioner did not make this argument in the Petition and, instead, raised it for the first time during oral argument; thus, it will not be considered. See Dell Inc. v. Acceleron, LLC, 884 F.3d 1364, 1369 (Fed.

Even if we were to consider this new argument, it would not be persuasive. As Patent Owner observes (PO Resp. 20), any processing performed by peripheral device 32 in paragraph 321 is on data received from the processing device and destined for the base station via the network, rather than data flowing in the direction of the first processed video data of claim 1.” slip op. at 22

    “gesture” must refer back to the same gesture reflects the plain meaning of the claim language. In each independent claim, the structure and usage of the language in dispute are the same. Only one gesture detection is recited, and there is no language reasonably indicating repetition or reiteration of detection for any reason at any time. Patent Owner’s position that to meet “the gesture” recitations, prior art “gestures” must all share a common starting point also makes sense and is appropriate. The same gesture must start from the same starting point or else it is not the same gesture. Specifying the understanding this way avoids treating two similar gestures as the same gesture, if they have different starting points. For instance, two taps may be the same in every way, except for their starting points. They are not the same gesture in the context of these claims.” slip op. at 19

    “Neither the tap-and-hold gesture in the bottom path of Kim’s Figure 7 nor the “long press input” and “long press event” of Kim such as that shown in Kim’s Figure 5 is the double-tap gesture Petitioner relies on to satisfy limitation [1.f]. Neither has been shown to have a common starting point with the double tap. Thus, Petitioner’s showing is inadequate. Limitation [1.i] recites: [1.i] when the magnitude of the duration of the gesture being detected on the touch screen on the object is greater than a second magnitude threshold, perform another operation. Pet. v. Petitioner explains: Kim teaches or renders [1.i] obvious. APPLE-1003, ¶62. Kim further describes “another operation” that is performed when the magnitude of the duration of the gesture is greater than a second magnitude threshold—specifically, a minimum threshold to be deemed an intentional touch. 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]. Kim states that, “[i]f an interrupt is not a request for the activation of the zoom mode as the result of determination in step 205, the mobile device can perform some action in connection with an interrupt (step 207),” shown in Figure 2a below. APPLE- 1004, [0050], FIG. 2a; APPLE-1003, ¶63. [Figure 2A of Kim is a flow diagram of a method for a touch-based control in a zoom mode (Ex. 1004 ¶ 20)] Kim additionally explains that if the mobile device determines that a detected user gesture does not correspond to any particular input event, “the mobile device disregards the received input event.” APPLE-1004, [0053]. Based on Kim’s disclosure of “disregarding” a received input, a POSITA would have understood that, for the detected interrupt (step 203) to be sufficient to cause the mobile device to “perform other action” (step 207), a magnitude greater than a minimum threshold value (e.g., the minimum threshold of an intentional user input) is relied upon, or rendered obvious, by Kim. APPLE-1004, FIG. 2a; APPLE-1003, ¶64. Thus, when the magnitude of the gesture is greater than a second magnitude threshold, the device “performs other action” (e.g., display requested menu). APPLE- 1004, [0050], FIG. 2a; APPLE-1003, ¶64. A POSITA would have understood that such an interrupt would be caused by a gesture that is longer in duration than the second threshold (as necessary to avoid the gesture from being disregarded), shorter than the duration necessary for a long press threshold, and a different gesture than a double tap gesture.

    “We agree with Patent Owner’s position that the language of the claim requires the fulfillment of all the listed conditions (for each “when” clause) to cause the performance of the recited function. As stated above, the natural reading of the conditions is that they are prerequisites; they must be satisfied for the program to perform the recited function(s). For the third scenario, for example, the condition that the first web page is displayed must be satisfied in order for there to be a hyperlink to a second web page, such that the program can detect whether the location of the first contact point corresponds to that hyperlink. Ex. 1001, 102:60−62, 103:32−33, 103:37−39. The duration of the first contact has exceeded the second duration threshold without ending that first contact, and with no movement of the first contact point. Ex. 1001, 102:66−67, 103:1−3, 103:33−36, 103:39−42.13 These conditions collectively set the characteristics of the gesture that endures for the required amount of time. “When” this particular gesture is detected, for 13 We note that other non-challenged claims, require determining that there is movement of the first contact and performing corresponding functions of displaying the movement. See, e.g., Ex. 1001, 108:9−24 (Claim 40, which depends from claim 1). the required duration, and recognizing the hyperlink is selected on the displayed first web page, then the three functions corresponding to these conditions in the third scenario are performed. This “when-then” relationship is conditional, as the parties seem to agree; but, we find, it is also causal. Because the cause of outputting the feedback with the actuator, displaying a menu, and further displaying a portion of the second web page to which the hyperlink pointed is that all the conditions were satisfied as required by the claim. Ex. 1001, 103:43−55. This is the plain and straightforward reading of the “when” clauses in claim 1.” slip op. at 15

    “Thus, Petitioner’s mapping as described above does not meet the requirements of the third “when” clause. We find that neither the snippet of Blumenberg nor the preview of Bhumkar is displayed in Petitioner’s proffered combination when the conditions of the third “when” clause are met. The condition of determining that the duration exceeds the “activation threshold” has no relationship to whether the display of the snippet or the preview occur. Blumenberg displays the link preview or snippet upon exceeding the 0.2 seconds or “selection threshold.” Ex. 1004 ¶ 49. Thus, there is no conditional relationship, much less a causal relationship between the display of the link preview or snippet and the “activation threshold” to which Petitioner has mapped the condition of the third “when” clause. The substitution of the snippet with Bhumkar’s “quick view” under Petitioner’s “simple substitution” rationale does not remedy the deficiency noted here. The function of “further display at least a portion of the second web page” (i.e., the “quick view”) is causally related to the “selection threshold,” and has no correlation to the duration determination, that the “activation threshold” has been exceeded. See Tr. 9:8−20 (Petitioner’s counsel arguing that “[t]here’s got to be correlation between them.”). Indeed, without a show of causality, the recited “further display” limitation is rendered irrelevant, in the Blumenberg-Bhumkar-Griffin combination. There is no need to “further display” because it already has been displayed, untethered to any condition recited in the third “when” clause.” slip op. at 41

    “We agree with Dr. Cockburn that the claims are not themselves programming code or even pseudo code. But they recite the functionality that the program instructions implement.15 We do not find useful Dr. Cockburn’s quibble with the word “instructions” recited in the claim as being too generic to import the understanding in the relevant art that programming logic is involved. Id. ¶ 55. Claim 1 recites more than mere “instructions.” As discussed above in Section II.E.1, the claim requires “one or more programs” and those “programs including instructions.” Ex. 1001, 102:56−59. We are persuaded by Dr. Mahon’s explanation concerning the perspective of a person of ordinary skill in the art and the implementation of instructions in programming logic that is executed by a processor, and that 15 Claim 42 is a method claim and does not recite the “program including instructions to” as claim 1 does. However, claim 42 does recite the processor and memory in parallel with the same functions recited in claim 1, and Petitioner has not argued that the scope of claims 1 and 42 differ in any material way. Ex. 1058 ¶ 55, n.3. Ex. 2008 ¶ 51. “from a software engineering standpoint, it would not be possible to implement a function that performs an action ‘when’ preconditions are met unless that function is designed to be executed because those preconditions have been detected.” Mahon Decl. ¶ 52. We credit Dr. Mahon’s explanations as they are reasoned and supported by the specification of the ’581 patent. Mahon Decl. ¶ 50. We are not persuaded by Dr. Cockburn’s rebuttal of Dr. Mahon’s reliance on the specification as supporting the understanding of a person of ordinary skill in the art because it dismisses the discussions of logic to implement the gesture detection and corresponding operations merely because these passages do not refer specifically to the three scenarios of the claim. Dr. Mahon’s discussion of general programming principles of conditional statements provides context relevant to the field of the invention. See Phillips, 415 F.3d at 1319 (“extrinsic evidence can help educate the court regarding the field of the invention and can help the court determine what a person of ordinary skill in the art would understand claim terms to mean” but warning about the flaws inherent in this type of extrinsic evidence). Accordingly, we are persuaded that Dr. Mahon’s testimony confirms the understanding of the plain and natural reading of the claim language to require a causal relationship between the conditions and the functions.” slip op. at 31

    “The difference between the parties’ positions is solely that Petitioner includes “human-computer interaction” as a relevant degree and “human computer interfaces” as relevant working experience. We need not resolve that difference, because no matter which stated level of ordinary skill is applied, all of our findings and conclusions would be the same and because neither party asserts the other party’s expert is not qualified as an expert.

    “We agree with Patent Owner (PO Resp. 13) that when Ording refers to user interfaces that are “intuitive and transparent,” “transparent” in that context does not mean optically transparent but something readily understandable, like the preceding word “intuitive.” That makes more sense in context. Patent Owner’s expert, Dr. Mahon, explains that Ording’s paragraph 28, where the phrase “intuitive and transparent” is found, is not concerned with optical transparency, but with increasing user satisfaction with portable devices by offering multifunctional operations on user interfaces based on finger input. Ex. 2012 ¶ 54. Neither Petitioner nor Dr. Cockburn explains why “transparent” in that context should mean optically transparent. We credit the testimony of Dr. Mahon, and reproduce paragraph 28 of Ording below: The various applications that may be executed on the device may use at least one common physical user interface device, such as the touch screen. One or more functions of the touch screen as well as corresponding information displayed on the device may be adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch screen) of the device may support the variety of applications with user interfaces that are intuitive and transparent. Ex. 1006 ¶ 28. We credit Dr. Mahon’s testimony that “Ording is addressing [in paragraph 28] user interfaces that are user-friendly and intuitive to navigate and operate.” Ex. 2012 ¶ 55.” slip op. at 33

    “The Zlider widget already is the least intrusive in the form as disclosed in the Ramos Paper/Ramos Video, placed off to the side of image content, not above and overlapping with image content. Petitioner’s semitransparency solution is for a self-created problem that otherwise does not exist, i.e., blocking the image by placing the Zlider widget directly over image content in Ording’s device. This is not reasoning with rational underpinning for making the Zlider widget partially semitransparent. Even assuming that the Zlider widget is properly placed directly over a camera image, making the Zlider widget semitransparent does not solve the intrusion problem, because the image and the Zlider widget may obscure each other, as shown in these illustrations provided by Patent Owner: [The illustrations show interference between a semitransparent Zlider widget and an underlying image] In its Reply, Petitioner asserts that it would have been well within the skill level of one of ordinary skill in the art to make adjustments to address a problem caused by such obscuring, such as by making the Zlider widget more visible as shown below: [The illustration shows one way Petitioner asserts one of ordinary skill in the art may apply to solve the obscuring issue (Reply 5–6)] Petitioner’s argument is misplaced. Although there may be graphic display techniques one of ordinary skill in the art may adopt to reduce the visibility problem if the Zlider widget were moved to directly above the image content as Petitioner proposes, that does not cure the problem of lacking a reasonable motivation to place the Zlider widget of the Ramos Paper/Ramos Video directly over image content. Still, there is the least obscuring and the least intrusion with the Zlider widget remaining where it is shown to be in the Ramos Paper/Ramos Video, side-by-side relative to the image content. It is irrational to make a modification that creates a problem, solely on the basis that a solution may be available to reduce the severity of the problem. Indeed, such a strained rationale shows that hindsight has played a part on Petitioner’s contention that a person of ordinary skill in the art would have put the Zlider widget over content as required by the claims.” slip op. at 30

    “Brown’s adapter tube 23 (i.e., the extended portion) does not extend radially from a longitudinal axis of valve assembly 13 (i.e., the toilet fill valve). Ex. 1021, Fig. 1. Mr. Jobin testifies that a POSITA would not be motivated to move adapter tube 23 from a vertical position to a radial position because “a radial extended portion is directly counter to the stated goals of Brown (e.g., reducing noise caused by turbulence), at least insofar system.” Ex. 2013 ¶ 251; see Ex. 1021, 1:9–62. Patent Owner’s argument is persuasive. Petitioner’s analysis and Dr. Cameron’s testimony is conclusory and does not sufficiently explain why a POSITA would be motivated to make the proposed modification to Brown. For example, Petitioner does not sufficiently explain how such a modification would result in a more compact toilet fill valve system that could be adapted to fit in more toilet tank designs. Further, neither Petitioner nor Dr. Cameron sufficiently address Mr. Jobin’s testimony regarding Brown’s desire for a quieter toilet. See Pet. Reply 23; Ex. 1036 ¶ 84.

  • Disclosure Requirements (§112) › Written description (Ariad)Written description adequateEntitled to earlier dateDecided for patent owner

    “description is an objective inquiry into the four corners of the specification from the perspective of a POSA. Using this test, the invention must be described in a manner sufficient to demonstrate that the inventor actually invented the claimed invention. Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010). “One shows that one is ‘in possession’ of the invention by describing the invention, with all its claimed limitations, not that which makes it obvious.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997). Written description is a question of fact judged as of the relevant filing date. Falko–Gunter Falkner v. Inglis, 448 F.3d 1357, 1363 (Fed. Cir. 2006). An ipsis verbis disclosure, however, is not necessary to satisfy the written description requirement. Vas–Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563 (Fed. Cir. 1991). The disclosure need only reasonably convey to a POSA that the inventor had possession of the subject matter in question, even if every nuance of the claims is not explicitly described in the specification. Id.; see Ariad, 598 F.3d at 1351. Patent Owner argues that the ’993 patent claims were “fully supported as of the filing date of at least the ’606 Application . . . March 11, 2004” because the ’606 Application discloses regulating water flow and a POSITA would know that appropriate devices for regulating water flow includes nonadjustable waterflow restrictors. PO Resp. 68; PO Sur-reply 28–30. Patent Owner’s argument is persuasive. The ’606 Application discloses: [W]hen the toilet fill valve 100 is open and water flows from the water inlet 103 to the water outlets 106 and into a toilet tank, an amount of water is also supplied to the bowl fill valve inlet 113 that flows through the bowl fill valve 109 and out the bowl fill valve outlet 116. By virtue of the manual setting of handle 119 valve 109 is regulated. In this manner, the flow of water is regulated so that enough water flows out of the bowl fill valve 109 to fill a toilet bowl without wasting any water down a drain. Ex. 1012, 47, ¶ 8 (emphasis added); see also Ex. 1001, 2:28–39. As can be seen from the passage above, the ’606 Application discloses regulating an amount of water supplied to a toilet bowl using a valve (i.e., a water flow regulator).

    “1. Analysis of Claims 1–18 Schuster is available as prior art if the ’993 patent is only entitled to its January 27, 2014, filing date and not entitled to claim priority to earlier filing dates of the parent applications. On its face, the ’993 patent claims priority to a number of earlier parent applications, including Application No. 12/786,904 (the ’904 Application) filed May 25, 2010, and the Application code 63. Petitioner contends that the ’993 patent is not entitled to claim priority to the filing date of the earlier parent applications, and, thus, Schuster, a parent application of the ’993 patent, is available as prior art.15 Pet. 91–92. Petitioner alleges that the earlier parent applications, specifically Application No. 12/786,904 (the ’904 Application), do not provide written description support for the ’993 patent’s claim term “water flow regulator.” According to Petitioner, “water flow regulator” encompasses both adjustable devices for restricting the flow of water (i.e., valves) and fixed devices for restricting the flow of water (i.e., restrictors). Pet. 15. Petitioner contends that the ’904 Application does not provide support for water flow restrictors and, thus, does not provide support for the broader claim term water flow regulators. Id. at 14–15, 91–92. Petitioner argues that only adjustable water flow devices (i.e., valves) are supported by the ’904 Application. Id. Petitioner, thus, asserts that earliest effective filing date of the ’993 patent’s claims is the filing date of its application, January 27, 2014. Id. at 92. To be entitled to claim the benefit of an earlier filing date under 35 U.S.C. § 120 each application in the priority chain must comply with the written description requirement of 35 U.S.C. § 112(a). See Hollmer v. 14 The parties do not dispute that the ’993 patent and the earlier parent applications, including the ’904 Application and the ’606 Application, have the same pertinent portions of their specifications. See PO Resp. 71, n.16; Ex. 1004 ¶ 324. 15 Schuster issued on January 31, 2012, from Application No. 12/786,904, filed on May 25, 2010. Ex. 1029, code (21), (22), (45).

    “2. Analysis of Claims 19 and 20 Claim 19 depends from claim 14 and additionally recites, “wherein the waterflow regulator comprises an adjustable water flow regulator that is configured to adjust the flow rate of the second portion of the water based at least in part on a setting of the adjustable water flow regulator.” Ex. 1001, 12:16–20. Claim 20 depends from claim 14 and recites the same additional limitation. Id. at 12:21–24. Claims 19 and 20, thus, require the water flow regulator to be an adjustable water flow regulator. Petitioner indicates that the earlier parent applications provide written description support for an adjustable water flow regulator. Pet. 91 (“[T]he ’904 application specification makes it clear that the adjustability of the bowl fill valve is a desirable and essential feature of the invention”); PO Surreply 28. Accordingly, Petitioner fails to meet its burden to show, by a preponderance of the evidence, that claims 19 and 20 are unpatentable over Schuster.” slip op. at 50

    “Patent Owner proposes that a person of ordinary skill in the art “would have a Bachelor of Science degree in Electrical Engineering, Computer Engineering, Computer Science, Human Computer Interaction, or a related technical field, with at least one year of experience working in the field of user interfaces and/or content management.” PO Resp. 11 (citing Ex. 2040 ¶ 53). The Decision on Institution adopted Petitioner’s proposed level of ordinary skill in the art. Inst. Dec. 10. We find Patent Owner’s stated level to be less precise than that proposed by Petitioner in that the modifier “at least” used by Patent owner imposes no upper bound on the amount of experience possessed by one of ordinary skill in the art. Also, Patent Owner states: “The difference between the Board’s definition and Patent Owner’s (EX2040. ¶53) does not change the arguments set forth herein.” PO Resp. 11.

    “In its Reply, Petitioner does not assert that the district court’s construction is incorrect. We agree with Patent Owner that the district court’s construction is better than Petitioner’s proposed construction, because for reasons indicated by Patent Owner, which are not disputed by Petitioner, settings in the computer, e.g., dedicated folders for each user are the user profiles, rather than simply data alone of any kind. Further, when asked about the appropriateness of the district court’s construction, counsel for Petitioner expressed that Petitioner has no objection to the Board’s adopting the district court’s construction for “user profile”: JUDGE LEE: So, you’d be fine with just going with the District Court’s construction? MR. HEINTZ: Yes, Your Honor. Tr. 15:22–24.

    “PO Resp. 30–31 (Figure 26 omitted). In its Reply, Petitioner still does not provide an articulated reason for placing user profile selection buttons, labeled with user names, within Horn’s panes 2601 or 2602. Reply 12–14. Although Horn does describe personalized profile, Petitioner points to no disclosure of Horn as to how a user would have selected his or her own profile from among a plurality of user profiles. Petitioner presents no reason for placing these user profile selection buttons, labeled with user names, gleaned from or suggested by Baumgartner, within either pane 2601 or pane 2602 in Horn’s workspace view. Further, pane 2602 contains “a list of all collections defined by MFS and the user,” and pane 2601 lists the source examined by the user to create his or her collections. Ex. 1005, 19:41–46. That disclosure suggests the contents of panes 2601 and 2602 are tied to one particular user. No rational basis is articulated by Petitioner to place user profile selection buttons within these panes which appear to be in the profile space of one user. For the foregoing reasons, Petitioner has not adequately accounted for limitation 16[b].” slip op. at 22

  • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

    “The test for sufficiency of a written description under 35 U.S.C. § 112 is whether the earlier application’s disclosure “reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). The specification must “clearly allow persons of ordinary skill in the art to recognize that [the inventor] invented what is claimed.” Id. The Court of Appeals for the Federal Circuit has explained: One shows that one is “in possession” of the invention by describing the invention, with all its claimed limitations, not that which makes it obvious. Id. (“[T]he applicant must also convey to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention. The invention is, for purposes of the ‘written description’ inquiry, whatever is now claimed.”) (emphasis in original). One does that by such descriptive means as words, structures, figures, diagrams, formulas, etc., that fully set forth the claimed invention.
