    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner

      “information” should be given its plain and ordinary meaning as “data,” and that Patent Owner’s narrower construction of “first information” and “second information” lacks sufficient support in the intrinsic record. We agree with Petitioner that the ’802 patent Specification defines “information” as data when it uses the phrase “information (i.e., data).” See Ex. 1001, 5:60–62 (“Information (i.e., data) to be transmitted may be received in a baseband digital system 250, such as a wireless digital baseband processor.” (emphasis added)), 11:30–32 (“In this example, the signals 911 and 912 carry the same information (data).” (emphasis added)). As the Federal Circuit has explained, a “specification’s use of ‘i.e.’ signals an intent to define the word to which it refers.” Edwards Lifesciences LLC v. Cook Inc., 582 F.3d 1322, 1334 (Fed. Cir. 2009). slip op. at 13

      “argument based on Fernandez alone, we find that Petitioner has not provided a sufficient evidentiary basis to support a motivation to remove the amplification from each of Fernandez’s signal generators 10A-10E and add a single power amplifier instead. See Pet. 76–77 Ex. 1003 ¶ 235. Petitioner’s only rationale for this modification to Fernandez is that “[a] single amplifier has several advantages compared to multiple amplifiers, including lower complexity, a single (vs. multiple) potential point of failure, and lower cost,” and that one of ordinary skill “would have found a single amplifier to be a simple matter of design preference.” Pet. 76–77. Dr. Almeroth simply repeats these cursory allegations without providing any further explanation or evidentiary support. Ex. 1003 ¶ 235. Moreover, Dr. Cooklev provides credible testimony that replacing Fernandez’s amplification in signal generators 10A–10E with a single amplifier would not necessarily have the advantages that Petitioner suggests. See Ex. 2013 ¶¶ 99, 104–105. For example, Dr. Cooklev testifies that a single amplifier would need to have a wider bandwidth than the multiple amplifiers used in Fernandez, which could cause potential stability issues. Id. ¶ 105. According to Dr. Cooklev, this wider bandwidth would require more circuit elements, and thus would not provide the reduction in space usage and power consumption that Petitioner asserts. Id. According to Dr. Cooklev, Montojo also points to several “substantial, and potentially impractical, drawbacks” of using a single amplifier for multiple signal generators, including power constraints imposed by spectral emission requirements and on-board battery capacity. Id. ¶ 104 (citing Ex. 1006 ¶¶ 7– 8). In light of this testimony, which we find credible, Petitioner has failed to provide sufficient explanation or evidence to support its assertion that one of ordinary skill would have found it obvious to replace the multiple amplifiers in Fernandez’s signal generators with a single amplifier.” slip op. at 65

      “We find credible and agree with Dr. Cooklev’s testimony that the predistortion signals from tables 17-1 and 17-2 “are cancelled out by Suzuki’s amplifier” 28. Ex. 2013 ¶ 50. Dr. Cooklev supports his opinion by referring to paragraph 1 of Suzuki, which states that Suzuki’s invention is directed to “a multi-band lookup table type predistorter” (such as the one implemented using lookup tables 17-1 and 17-2 in Figure 6) that “compensates for a distortion of a power amplifier.” Ex. 2013 ¶ 54; Ex. 1004 ¶ 1. Dr. Cooklev’s opinion is also supported by paragraph 3 of Suzuki, which explains that a conventional digital predistorter uses a lookup table “for linearizing non-linear characteristics of an amplifier.” Ex. 1004 ¶ 3; Ex. 2013 ¶ 54. Dr. Cooklev further supports his opinion by relying on Suzuki’s disclosure in paragraph 46 that power amplifier 28 is “subject to distortion compensation” by the predistorter, and that distortion components in the signal output by the amplifier are canceled by “distortion compensation data [that] are read out from the lookup tables 17-1 and 17-2 and provided to the adders 13-1 and 13-2, respectively.” Ex. 1004 ¶ 46; Ex. 2013 ¶ 54. And, Dr. Cooklev’s opinion is supported by Suzuki’s disclosure in paragraph 47 that the distortion compensation added by adders 13-1 and 13-2 add the distortion compensation data from lookup tables 17-1 and 17-2 “to perform distortion compensation (addition of predistortion)” to “signals to be transmitted.” Ex. 1004 ¶ 47; Ex. 2013 ¶ 54. Petitioner agrees that the distortion compensation data from lookup tables 17-1 and 17-2 “are added to the respective frequency band from” input signal ST “in order to predistort the output signal, which is then transmitted,” and does not dispute that the distortion compensation data from lookup tables 17-1 and 17-2 is ultimately cancelled out by the distortion created by amplifier 28. Pet. Reply 8. In light of the above evidence, we agree with Patent Owner that Suzuki’s distortion components from lookup tables 17-1 and 17-2 in Figure 6 (which Petitioner relies on for the first and second digital signals in limitations 10a and 10b) are cancelled out by the distortion created by power amplifier 28 before the signal is ultimately transmitted. We agree with Petitioner that these first and second digital signals include data in the form of distortion compensation data. However, because these signals are cancelled by the distortion from amplifier 28 before transmission, the data from these signals is never transmitted. Thus, the first and second digital signals identified by Petitioner (the distortion compensation data from lookup tables 17-1 and 17-2) do not comprise data “to be transmitted,” as limitations 10a and 10b require.” slip op. at 35

      “The claim language and specification define and describe an “activation cue” in functional terms: a data communication from an external source is received by the cell phone and recognized as an activation cue if it causes the switching element to be assigned its first (activated) state. Ex. 1001, 9:28–31, 9:42–46, 10:14–16, 13:55–60, 14:53–59, 15:4–6, 19:20–26. Patent Owner agrees that “upon an activation cue being received by portable electronic device 10, switching element 44b switches to its activated state.” Resp. 19 (quoting Ex. 1001, 10:14–16). The activation cue may be a predetermined bit sequence, a predetermined contactless data transmission, continuously emitted, pulsed, or punctual, but these are unclaimed non-limiting embodiments of the preferred form of data transmission. Id. at 9:25–26 (“for example a predetermined bit sequence”), 11:20–22 (“One example . . . emit an activation cue in the form of a predetermined contactless data transmission”), 14:65–15:3 (continuously emitted, pulsed or punctual cue).

      “operatively linked to said electronic circuit” under 35 U.S.C. Section 112, sixth paragraph or not, the result is the same. We note there is no presumption of applying means-plus-function analysis to the switching element, because the limitation does not use the words “means for” that would mandate such claim construction treatment, and “switching” may invoke structure as well as function. See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1349–1350 (Fed. Cir. 2015) (en banc) (holding that “use of the word ‘means’ creates a presumption that § 112, ¶ 6 applies”). Regardless, we look to the meaning of the claim phrase at issue in view of the specification. We determine that the ’294 patent provides a clear, concise meaning for the switching element upon which both parties rely for construction. Patent Owner’s express agreement with Petitioner, that the claimed switching element is described in the ’294 patent as “any type of device allowing data to be conveyed according to alternate data conveyance operations in response to an activation cue being received by transceiver 18 or not,’” is particularly telling because it is not consistent with Patent Owner’s argument that the switching element means “switching of the data.” Resp. 7, 31 (citing Ex. 1001, 9:28–318). The claim language does not recite, and the specification does not describe, the switching element as a device that switches the data. Therefore, we determine the claimed “data conveyance switching element” means any type of switching device that allows data to be 8 We presume Patent Owner’s citation to “Exh. 2001, 9:28-31” on page 7 was intended to be a citation to the ’294 patent (Ex. 1001), as cited on page 31. whether or not an “activation cue” is received by the cell phone “cue receiver.”” slip op. at 21

      “[external] data exchange device” as a device with a data transceiver coupled to a circuit that carries out the function of exchanging data. Pet. 7–8 (citing Ex. 1001, 2:14–17, 4:7–14, 9:3–6; Ex. 1003 ¶¶ 67–68). As above, whether we construe the “[external] data exchange device” under 35 U.S.C. Section 112, sixth paragraph or not, the result is the same. Patent Owner, quoting the description of a data exchange device in the ’294 patent, contends that a “[external] data exchange device” “can be any sort of data exchange device comprising an electronic circuit (not shown) therein and a data transceiver 9a.” Resp. 8 (quoting Ex. 1001, 9:4–6). Patent Owner also responds to the Petition by clarifying that “[a]n external data exchange device is not a transceiver but a device with a transceiver.” Id. (citing Ex. 2001 ¶ 48). Petitioner argues in reply that Patent Owner does not contest Petitioner’s mappings of Mooney’s “cordless telephone base unit” or “cellular network infrastructure” to the claimed data exchange devices, such that no construction is necessary to resolve the dispute. Reply 5 (citing Resp. 16–37; Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011)). Limitations [1.c] and [1.d] recite “a first [second] data transceiver operatively linked to said electronic circuit [in the cell phone],” both of which are defined functionally as “for exchanging data between said electronic circuit [in the cell phone] and a first [second] external data exchange device over a first [second] communication link.” Nothing in the the other independent claims, further limits the form or function of the “[external] data exchange device,” although a device external to the cell phone may invoke additional structure. We determine the plain meaning of “[external] data exchange device” as claimed and described in the ’294 patent governs: any [external] device that comprises an electronic circuit and data transceiver for exchanging data with the electronic circuit in the cell phone over a communication link. slip op. at 22

      “specification is the ‘single best guide to the meaning of a disputed term,’ . . . and ‘is, thus, the primary basis for construing the claims.’” Trs. of Columbia Univ. in City of New York v. Symantec Corp., 811 F.3d 1359, 1362 (Fed. Cir. 2016) (citations omitted). Although Patent Owner contends that the Specification disparages systems that impose significant restrictions on the possible choices of frequencies (PO Resp. 21), we find availing Petitioner’s contention that “[s]upport for Patent Owner’s construction is absent from the specification.” Pet. Reply 10. As Petitioner points out, Patent Owner’s claim construction “appears to be based on a single paragraph of the ’443 patent referring to preexisting ‘synchronization schemes [that] restrict the phase relationship and relative frequencies of the clocks.” Id. That is, the only reference by Patent Owner to the Specification is that the Specification states that “Some synchronization schemes restrict the . . . relative frequencies of the clocks, thereby eliminating the need for hardware arbitration [27]. Unfortunately, these schemes impose significant restrictions on the possible choices of frequences.” PO Resp. 26 (citing Ex. 1001, 6:32–36). We agree with Petitioner that such disclosure in the Specification “does not describe how these synchronization schemes ‘restrict the phase relationship and relative frequencies’ with any specificity.’” Pet. the Specification that some schemes impose restrictions on the possible choices of frequency is not a disparagement of any system that has limited choices of frequency or would preclude the claims from covering such prior art techniques. Instead, as Petitioner points out, the Specification of the ’443 patent states “[t]he preferred embodiment uses four domains […] so that domains may vary somewhat in size and still be covered by a single clock.” Id. (citing Ex. 1001, 5:57–59). As Dr. Baker testified in support of Petitioner’s contention, “the preferred embodiment of the ’443 patent relies on a single external master clock that distributes a signal to the local PLL of each domain.” See Ex. 1032 ¶ 9. Thus, although Patent Owner contends that clock signals generated based on a master clock cannot be interpreted to be generated independently of the clock signals generated for others of the plurality of domains (PO Resp. 49), we agree with Petitioner that such claim construction would “exclude[] the preferred embodiment of the ’443 patent,” which is disfavored. Pet. Reply 11. For the reasons discussed above, we conclude that “changeable independently” of the other domains does not require that the separate clocks in the plurality of domains be globally-asynchronous.” slip op. at 12

See Kimberly-Clark v. Johnson & Johnson, 745 F.2d 1437, 1445 (Fed. Cir. 1984). Here, Patent Owner does not provide any evidence showing every element of the claims in physical or tangible form, as required, but rather contends that the Specification refers to the Paper, wherein the Paper stated that simulation using a software, SimpleScalar, was performed. PO Resp. 16. We are persuaded by Petitioner’s contention that the SimpleScalar simulation was not an actual reduction to practice of the claimed invention. Pet. Reply 12.

And as Petitioner points out, “Patent Owner has produced no evidence of any physical prototype of the claimed microprocessor that could have validated the simulation.” Pet. Reply 13–14.

      “Here, we find that Petitioner has not met its burden to prove that one of ordinary skill in the art would have recognized that “the functional units of Georgiou operate asynchronously since they have different clocks.” Pet. 74 (citing Ex. 1002 ¶¶ 53–56, 211–219). Specifically, although Petitioner relies on Georgiou for teaching different clocks, Petitioner’s conclusory statement that such application would operate asynchronously requires gapfilling. Id.

Without evidentiary support, we are left with speculation and impermissible hindsight. See in Re Wagner, 379 F.2d 1011, 1017 (CCPA 1967). We decline to engage in speculation.

Patent Owner’s contention and the supporting testimony of Dr. Madisetti does not address Shiplacoff’s teaching of using a gesture, such as Shiplacoff’s flick gesture, to return to launch screen. We agree with Petitioner and Dr. Terveen in finding that Shiplacoff’s disclosure that “returning to the launch screen . . . is performed by performing a gesture” (Ex. 1004 ¶ 99) such as a flicking gesture (Ex. 1004 ¶¶ 126, 129; Ex. 1023 ¶ 13) teaches using a flicking gesture to return from home screen to launch screen.

Because Dr. Terveen’s testimony is consistent with and supported by the teachings of Shiplacoff as a whole (in contrast to that of Dr. Madisetti), we credit the testimony of Dr. Terveen in finding that using a gesture to return from home screen to launch screen as taught by Shiplacoff, where the gesture is a flick gesture as taught by Shiplacoff, yields the predictable result of using a flick gesture to return from home screen to launch screen.

We agree with Petitioner and Dr. Terveen, that based on the teachings of Shiplacoff (and, by incorporation, Duarte), a person of ordinary skill in the art would have recognized that a flick started in area 102 or near an edge of screen 101 and continuing onto screen 101 would be distinguished from a flick entirely within screen 101 based on location, and would perform a different function. Ex. 1023 ¶¶ 18–19. We also agree with Petitioner and Dr. Terveen, that Duarte teaches associating a gesture with one function when a modifier key is not pressed, and associating the same gesture with a different function when the modifier key is pressed, such that a flick performed when the key is not pressed would perform one function such as scrolling and a flick performed when the key is pressed would perform another, such as changing the display mode. Reply 15 (citing Ex. 2003 ¶ 64; Ex. 1023 ¶ 20).

      “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 has been shown to have a common starting point with the double tap. Thus, Petitioner’s showing is inadequate.

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].

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.

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.

      “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

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. In the Decision on Institution, we adopted Petitioner’s stated level of ordinary skill in the art. Inst. Dec. 8.

      “Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). Petitioner asserts that “no claim terms need be construed to resolve issues of controversy in the present Petition.” Pet. 3. Patent Owner agrees that “no formal constructions of any claim terms are necessary.” PO Resp. 7. We agree with the parties that no express construction of any claim term is necessary.” slip op. at 9

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

      “First, we find that Hackborn clearly discloses an embodiment in which swiping the finger, not just mere contact without motion (i.e., a tap), moves the blades of grass in the background wallpaper. Hackborn explicitly states: “In the example shown in FIG. 1, a user is swiping her finger across a touch-sensitive display screen of the computing device. 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
