    “1. Limitation 3(da) The issues on remand revolve essentially around limitation 3(da): Limitation 3(da) – storing the inputted biometric signature in a memory at a memory location defined by the provided card information; Ex. 1001, 12:61–63. Considering limitation 3(da) in our Original Decision, we explained that during an enrollment process the claimed “biometric signature,” e.g., a fingerprint, is not yet stored in the memory, and no memory location or address has been “defined,” as in “set” or “established,” in the memory for storing the fingerprint, until card information is received. Once the card information and fingerprint are received during enrollment, the card information provides data that establishes where, i.e., at what memory location or address, the system will store the fingerprint data.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentable

    “Tsukamura’s index number N index does not teach or suggest much more than Hsu’s using “an account number or employee number, to access a fingerprint database (44) and retrieve reference fingerprint data previously stored there during an enrollment procedure.” Compare Ex. 1004, code (57), with Ex. 1005, 4:7–11. That is, both references arguably teach defining, i.e., setting or establishing, a certain location in a database for biometric data. For example, as described above, Tsukamura’s fingerprint template Temp is Id. 4:7–11, 50–54. However, neither Petitioner, nor Mr. Lipoff, persuasively explain how or why Tsukamura’s fingerprint template Temp is set or established “at a memory location defined by the provided card information” as recited in claim limitation 3(da). Taking a close look at Petitioner’s testimonial evidence as to claim 3, we first note Mr. Lipoff testifies that Tsukamura’s index number specifies the physical memory location in the memory. Thus, Tsukamura discloses defining, dependent upon the “index number N index,” a memory location for storing a biometric signature (e.g., a fingerprint template), i.e., the memory location is specified by the index number, under the Second Construction. In my opinion, if the Tsukamura implementation were used for Sanford-Hsu database, each user/account number would specify a different entry (index number) in the database. Ex. 1006 ¶ 394. This is consistent with our understanding of Tsukamura, and we can agree that Tsukamura teaches defining—that is, setting or establishing—a location for storing the biometric signature at “index number N index.” See Ex. 1005, 4:7–11. But, concomitant with the Federal Circuit’s point, such an associative link does not sufficiently explain how one of ordinary skill in the art would have understood Tsukamura’s IC card information to define “as in ‘set’ or ‘establish[]’” a memory location, as our claim construction requires. See Section II.C.3.” slip op. at 22

Although neither party actually identifies that term as needing interpretation and neither party actually provides a claim construction analysis to support its respective position, the parties do dispute whether the evidence presented shows a “trigger,” both presumably giving that term its plain and customary meaning. In other words, while both parties appear to agree “trigger” carries its plain meaning, in application, the parties’ dispute regarding the particular limitations including that term appears to turn, not over what the evidence discloses, but only on whether the disclosure satisfies the plain meaning of “trigger” (see infra § II.E.2). Accordingly, while we apply the plain meaning of “trigger” in this proceeding, and in doing so, we address which party has properly applied the plain meaning and, in doing that, we address the scope properly afforded to “trigger.” That analysis, however, is done below in the context of the limitation in which this issue arises (see id.).” slip op. at 8

    “has now been developed, and in view of both parties’ arguments, we find Petitioner has persuasively shown that modifying Ono’s peripheral device (i.e., communications module 44) to include an input device/physical actuator like the one described for Ono’s remote controller 69 to control the display of image data from a particular user’s computer would have been obvious to a skilled artisan at the time of the invention. More specifically, Petitioner has shown persuasively Ono shows that the use of an input device/physical actuator to send a signal that causes a participant’s computer to transmit and control the image data presented on a shared display in an image display system was a known technique (see Ex. 1005 ¶¶ 7, 44–48, 66– 71, 77–78, 80–89, 144, Figs. 3, 6, 8, 9; Ex. 1002 ¶¶ 85–100, 121–127) and available location for such an input device/physical actuator to initiate the transmission of data (see Ex. 1007 ¶¶ 6, 18, 20, 22–23, 26, 28, 46, Fig. 1; Ex. 1002 ¶¶ 92–100). Petitioner has also persuasively shown that a skilled artisan recognized benefits to giving a participant the ability to locally control the display of their computer’s image data.

When Ono and Corbett are considered together as a whole from the perspective of a skilled artisan, therefore, it is clear that applying a similar input device/physical actuator to Ono’s peripheral device would have been recognized to result in the benefit of providing a participant with the same ability to send a signal that causes a participant’s computer to transmit and control the image data presented on a shared display from their computer within an image display system. As a result, a motivation has been established because the combination is an application of a known technique to derive a known benefit using prior art elements according to their established functions.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

    “that, from their perspective, the plain meaning of the term “trigger” does not exclude intervening steps between a user’s action on an input device and the ultimate transfer of the user selected arbitrary media content. Pet. Reply 11– 12 (indicating that “trigger” encompasses “a process that begins with and thus is triggered by a user pressing a button followed by an ‘image transfer’ from a PC to a projector”). For its part, Patent Owner maintains (at least implicitly) that intervening steps are excluded from the plain meaning. Neither party addresses with more specificity why, or why not, the scope of “trigger” supports their positions, however. Having now the complete record before us, we find that out preliminary assessment was wrong because the plain meaning of the term “trigger” does not exclude intervening steps between the cause-and-effect relationship of the trigger and the result it is intended to cause. Take, for example, a simple gun. Pulling the “trigger” to fire a gun necessarily includes intervening steps to occur: the trigger releases a hammer that, in turn, contacts a blasting cap within a bullet casing, which is what actually causes the gunpowder to ignite (i.e., fire) and expel the bullet. And there is no evidence in this record to suggest that this customary understanding of the word “trigger” is any different in the electrical arts, other than the trigger and result are generally electrical in nature, rather than mechanical. We find no clear disavowal of claim scope within the intrinsic record of the ’951 patent to indicate that the term “trigger” was intended to be understood any differently to exclude any intervening steps between a user’s action on an input device and the resulting transfer of user selected arbitrary media content. intervening steps would exist because the input device does not actually do the transferring of the media content; instead, the claims recite the transferring is “from the transmitter to the wireless communications network and [then] to the base node.” See Ex. 1001, 11:3–48, 27:62–28:1 (claim 1), 28:62–67 (claim 9), 29:42–46 (claim 16), 30:36–44 (claim 21) (emphasis added). A skilled artisan would have recognized that there would be intervening steps between the input device being acted upon and the content being displayed by base node’s display. See Ex. 1083 ¶¶ 11–12. In the claims, the input device is analogous to a gun’s trigger, the user carrying out a user action on the input device is analogous to pulling a gun’s trigger, and the transfer of user selected arbitrary media content is analogous the gun expelling a bullet. In both cases, there can be, and usually are, intervening steps, moreover, in both cases, inadvertent things can happen that may prevent the intended result (e.g., in the case of a gun, the hammer can jam; in the case of an input device, a connection can be rejected). Nevertheless, in both cases, the trigger is the thing that initiates an automated process that leads to a particular result, unless a conditional error occurs.” slip op. at 31

Deforche solves this problem by using the processing device’s pre-installed drivers, which can be for a human interface device, to set up a modem/host communication interface for communication. Id. ¶¶ 4, 9. Because “[d]ata traffic from the computer device towards the wireless communication network and vice versa is routed over this modem/host communication interface and uses the generic communication protocol provided by the preinstalled generic driver,” Deforche states this “has the advantage that the need for a specific driver for the communication between the wireless modem device and the computer device can avoided” and “the advantage that a user can use the wireless modem device on a computer device on which he has no administrator rights, i.e. a computer specific driver for the wireless modem device.” Id. ¶ 9. “The motivation-to-combine analysis is a flexible one.

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “stated by Patent Owner. Ex. 2001 ¶ 25. This proposed level of skill is nearly identical to that proposed by Petitioner. Unlike Dr. Larson, however, Dr. Ricketts states his “opinion,” without stating the facts, data, or factors that he considered in reaching his opinion. Accordingly, we give his testimony little probative weight. 37 C.F.R. § 42,65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). For purposes of this Decision, based on the prior art, the sophistication of the disclosed technology in the ’593 patent, and Dr. Larson’s testimony, we adopt Petitioner’s definition of the level of ordinary skill, which is that a person of ordinary skill in the art would have had: at least a bachelor’s degree in electrical engineering or a related subject and two or more years of experience in the field of RF circuit design and/or power supplies for RF circuits, or at least five years of work experience and training in the design and development of RF circuits and/or power supplies for RF circuits. Less work experience may be compensated by a higher level of education, such as a master’s degree.” slip op. at 15

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed petitioner constructionDecided for petitioner

    “on the construction of the claim term “power efficiency,” we agree with Petitioner and its declarant, Dr. Larson, that a person of ordinary skill (i.e., a degreed engineer with two or more years of experience in the field of RF circuit design and/or power supplies for RF circuits) would have understood that to determine the power efficiency of a circuit, one would measure the components or characteristics of power, such as voltage and current, to determine the output power of the power supply compared to its input power. Based on our construction of the claim term “power efficiency,” we also note that the claims only require performing a bypass function when the efficiency threshold is exceeded. The claims do not require a power efficiency ratio to be measured or calculated. Thus, we decline Patent Owner’s attempt to limit the claim term “power efficiency” to a ratio.” slip op. at 30

    “Section II.D.2 of this decision), Hau teaches a bypass controller 74 (purple) which receives a signal Pdet from a power detector (pink) and activates a bypass switch 72 (purple) when the signal Pdet exceeds a predetermined threshold (in response to a power efficiency of the power supply exceeding a predetermined threshold). Id. at 28 (citing Ex. 1007, 5:43–51, 6:57–7:20). According to Petitioner Hau discloses that the strength of the signal Pdet, the power output of the amplifier PA1, and the supply voltage Vcc2 are all proportional. Id. at 29 (citing Ex. 1007, 6:22–44; Ex. 1003 ¶¶ 122–123. Petitioner concludes, therefore, that Pdet is an indicator of the power output by the DC-DC buck regulator at Vcc2. Id. Petitioner also concludes that because input power is supplied to the DC-DC buck regulator from a fixed voltage, Pdet is also an indicator of the power efficiency of the DC-DC buck regulator because higher power indicated at Pdet indicates greater efficiency relative to the fixed input power. Pet.29 (citing Ex. 1003 ¶ 123). Dr. Larson’s testimony supports Petitioner’s conclusions. Petitioner also asserts: when Pdet exceeds the predetermined threshold, Hau’s bypass controller 74 activates bypass switch 72 and deactivates the DC- DC converter (which is a PWM switching device in the combination of Hau and Yoshida) (deactivates the switching device) to pass the input voltage directly to the output voltage Vcc2 (passes the input voltage to the output voltage node). Pet. 30 (citing Ex. 1007, 5:44-51, 6:61, 66; Ex. 1003 ¶¶ 125-126).” slip op. at 39

  • Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightUnpatentableMotivation foundUnpatentable

    “According to Petitioner, it would have been obvious to a person of ordinary skill “to set Hau’s predetermined threshold to correspond to the point at which a fixed power supply (e.g., the bypass pathway of Hau) becomes more efficient than the down-converted power supply, as taught by Sahu.” Pet. 50–51 (citing Ex. 1007, 6:63–66; Ex. 1003 ¶¶ 166–167). Petitioner also asserts a person of ordinary skill “would have recognized that Sahu’s efficiency graph shows performance for a particular modulation scheme”, and that the resulting efficiency of the system using that modulation scheme “correlates with the efficiency of the communication waveform in that scheme (based on a communication waveform efficiency).” Id. at 51 (citing Ex. 1003 ¶ 168). Petitioner concludes that a person of ordinary skill “would have understood and found it obvious that basing the predetermined threshold of Hau on the point where a fixed power supply becomes more efficient as taught by Sahu is programming the threshold voltage based on a communication waveform efficiency.” Id. at 51 (citing Ex. 1003 ¶ 168). We find Petitioner’s contentions persuasive. Patent Owner asserts it is “hindsight” to rely on Sahu. PO Resp. 51 (a person of ordinary skill “would not have equated Sahu’s fixed-supply system with Hau’s bypass pathway without the benefit of hindsight”). According to Patent Owner, “Petitioner used the disclosures in the ’593 patent as a road map for reasons to combine Sahu and Hau/Yoshida.” Id. (citing Ex. 2001, ¶¶ 174–75). Patent Owner also asserts a person of ordinary skill “would have recognized that Figure 8(a) of Sahu “relates to specific devices that were tested in Sahu.” Id. at 50. We find these assertions unpersuasive. We have discussed above the” slip op. at 57

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “The parties agree that formal education could substitute for practical experience, and vice versa. Pet. 6, PO Resp. 18. The parties’ proposed levels of ordinary skill appear to be substantially similar, supported by testimonial evidence, and consistent with the asserted prior art and the types of problems and solutions identified in the ’738 patent. See, e.g., Ex. 1001, 1:6–61. Although we discern no difference in the outcome of this decision from choosing one over the other, we adopt Petitioner’s proposed level of skill for this decision. The outcome of our decision would be the same under Patent Owner’s proposal.” slip op. at 7

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

    “We find insufficient support in the specification or prosecution history to narrow the term “haptic effect” to only one that has not been modified or combined with another haptic effect. The ’738 patent still refers to combined or modified haptic effects as a “haptic effect.” Ex. 1001, 11:35–38 (“a haptic effect may further be modified or combined with another haptic effect” and “the haptic effect can include one or more haptic effects”). We also find no support for importing into the construction of “haptic effect” the ’738 patent’s example in which a haptic effect can be “based on the proximity signal and the touch sensor signal.” That is already an explicit claim limitation. Id. at 14:19–20 (“generate a haptic output signal based at least in part on the first [proximity] and second [touch] sensor signals”). Including that limitation as part of the construction of “haptic effect” would render the limitation superfluous. See Apple, Inc. v. Ameranth, Inc., 842 F.3d 1229, 1237 (Fed. Cir. 2016) (“The Board was correct to not include in its construction of ‘menu’ features of menus that are expressly recited in the claims . . . . Construing a claim term to include features of that term already recited in the claims would make those expressly recited features redundant.”). We also disagree with Patent Owner that the ’738 patent’s references to haptic effects modified or combined with other haptic effects are unclaimed embodiments. The ’738 patent discloses that a proximity-based haptic effect may be combined with a touch-based haptic effect, such as when “a particular haptic effect associated with a particular control on a user interface element [is] further . . . modified or combined with another haptic effect based on the proximity sensor signal,” or when “the haptic effect [to be output by the processor] . . . include[s] a haptic effect meant to confirm ‘pushing’ on a virtual button.” Ex. 1001, 11:32–40. These examples are consistent with the claim language and we find no credible evidence in the record that these embodiments are intended to be excluded from the claimed invention. Thus, we agree with Petitioner that it would be incorrect to construe the term “haptic effect” to include the extraneous limitations Patent Owner proposes. We also agree with Petitioner that a person of ordinary skill in the art reading the ’738 patent disclosure would have understood that a combined or modified haptic effect is still a haptic effect.” slip op. at 11

  • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)UnpatentableUnpatentable

    “To show anticipation under § 102, a petitioner must locate every element in a claim, arranged as recited in the claim, in a single prior art reference. See Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1369 (Fed. Cir. 2008). The limitations may be present in the reference “either explicitly or inherently.” In re Schreiber, 128 F.3d 1473, 1477 (Fed. Cir. 1997). In making this determination, we consider the reference “together with the knowledge of one of ordinary skill in the pertinent art.” In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994) (citing In re Samour, 571 F.2d 559, 562 (CCPA 1978)).” slip op. at 13

    “We find Petitioner’s arguments persuasive and disagree with Patent Owner’s arguments to the contrary. Ku discloses summing two overlapping vibration signals, one “based at least in part on” data from a proximity sensor and another “based at least in part on” data from a touch sensor. Ex. 1008, Fig. 12 (items 705, 710, and 715). The summed signal 715 is the basis for generating what the user would perceive as a single haptic effect. See Ex. 1004 ¶ 210–212. This meets limitation 1F. We agree with Petitioner’s argument as to why there would have been a motivation to modify Pratt to include Ku’s teachings. Petitioner’s argument is not merely that Pratt was ready for improvement; Petitioner persuasively argues that a person of ordinary skill in the art would have had reason to add Ku’s method for confirming that the user has touched the intended icon to Pratt’s system. Both Pratt and Ku already disclose using both proximity and touch data in generating a haptic effect, and based on the evidence of record, we are of the view that combining the two teachings would not have been uniquely challenging or otherwise beyond the level of ordinary skill in the art. See Leapfrog Enters., Inc. v. Fisher-Price, Inc., 485 F.3d 1157, 1162 (Fed. Cir. 2007) (“Leapfrog presents no evidence that the inclusion of a reader in [electronic children's toys] was uniquely challenging or difficult to one of ordinary skill in the art.” (citing KSR, 550 U.S. at 419–420))” slip op. at 32

    “person of ordinary skill in the art (“POSITA”) “would have at least a bachelor’s degree in electrical engineering or a related field and at least two years of experience with lighting technology.” Pet. 2 (citing Ex. 1017 ¶ 35). 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 . . . . [and] that it is important to provide light that evenly illuminates the target subject or object to minimize reflected glare and shadows.”). 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). Patent Owner disputes Petitioner’s contentions regarding what a POSITA would have understood. Prelim. Resp. 12–13 (“[O]ne of ordinary skill in the art would have understood that analog and digital cameras have different operating principles and lighting requirements [and] Petitioner’s lack of appreciation for the suitability and unsuitability of different lights for different applications infects and dooms its invalidity analysis.” (citing Ex. 2036 ¶¶ 36–47)). and years of experience required for a POSITA. Pet. 2; Prelim. Resp. 12. For purposes of this Decision, we consider a person of ordinary skill in the art to have a bachelor’s degree in electrical engineering or related field and two years of practical experience in lighting technology, and that additional experience may substitute for education and vice versa, which is consistent with the level of skill reflected in the ’729 patent and prior art of record. See Exs. 1001, 1005–1010, 1012–1015; see also Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and need for testimony is not shown” (quoting Litton Indus.
