“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.

“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.

“1. Motivation to Combine Becerra and Couckuyt Petitioner argues that a person of ordinary skill in the art would have been motivated to combine the teachings of Becerra and Couckuyt because such a person would have recognized that Couckuyt discloses useful techniques of assigning data to Becerra’s charts, including assigning data to each axis. Pet. 34 (citing Ex. 1005 ¶¶ 19, 52, Fig. 5; Ex. 1003 ¶ 224). Petitioner contends that Couckuyt discloses associating data from a “spreadsheet document” with a chart, such as a “bar graph.” Id. at 35 (citing Ex. 1006, 6:1–37; Figs. 3a, 3c). below. Petitioner’s annotations to Figure 4 identify “Drop Zones” in red and “Data Fields” in Blue. Id. at 36. Petitioner contends Couckuyt discloses a “drag-and-drop user interface (DDUI) . . . associated with a data source, such as the two-dimensional data source 300,” and Figure 4 illustrates the DDUI permitting “value data fields and the characteristic data fields . . . to be dragged and dropped into drop zones.” Id. at 35–36 (citing Ex. 1006, 7:10–13). Petitioner contends that a “primary benefit of the charting DDUI is that the user can quickly change the data that is being presented in the chart,” and using Couckuyt’s techniques, a user can “quickly change the data” and see the desired effects. Id. at 36 (citing Ex. 1006, 1:18–19; Ex. 1003 ¶ 228). Petitioner contends that when Becerra’s control panel includes multiple charts, Couckuyt’s techniques would allow dragging-anddropping data from a data source to multiple charts, and would simplify the process of assigning data to multiple control panel components. Id. at 36–37 skill in the art would have also had a reasonable expectation of success combining Becerra with Couckuyt because the combination would amount to nothing more than incorporating Couckuyt’s well-known drag-and-drop techniques into Becerra’s system. Id. at 37 (citing Ex. 1003 ¶¶ 229–231). Patent Owner responds that Couckuyt focuses on selecting a data icon that corresponds to dragging and dropping data fields, not dragging and dropping data, while Becerra teaches that selecting various data ranges from the spreadsheet is desirable. PO Resp. 36–37 (citing Ex. 1004 7:48–52; Ex. 2001 ¶ 146). According to Patent Owner, a person of ordinary skill in the art would not have been motivated to merely select data fields that do not limit the selected data in any way. Id. Patent Owner further argues Becerra’s method of binding components to a spreadsheet range and extracting formulas from a spreadsheet teaches away from the multiple chart generation scheme of Couckuyt that uses drag and dropping of data fields. Id. at 37. According to Patent Owner, Couckuyt is directed to the need for a charting DDUI that can generate multiple charts at the same time and such a need does not exist in Becerra which in turn is focused on creating a control panel that is an interactive graphics simulation.

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).

“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).

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.

“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

“a) Whether Dr. Almeroth’s Testimony should Be Given Little Weight Patent Owner argues that we should give little weigh to the testimony of Dr. Almeroth because Dr. Almeroth’s testimony is allegedly inconsistent across the related inter partes reviews. PO Resp. 11–16; PO Sur-reply 21– 22. We have reviewed the disputed portions of Dr. Almeroth’s testimony and, when read in context, we are not persuaded that the testimony is inconsistent so as to be afforded little weight.

“Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the Deutschland Gmbh v. Mylan Pharms. Inc., 66 F.4th 1373, 1377 (Fed. Cir. 2023) (quoting In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004) (citations omitted). We are persuaded by Petitioner that Mardiks meets at least the second test because both the ’237 patent and Mardiks “are directed to solving the same problem of using standard, pre-installed generic drivers, such as human interface device (HID) drivers, to access programs stored on peripheral devices.” Pet. Reply. 3–5; See Ex. 1001, 5:38–40; Ex. 1026 ¶¶ 3, 28. We, thus, are not persuaded by Patent Owner that Mardisk is non-analogous art. slip op. at 16

“term “pre-installed generic driver.” Pet. 13; PO Resp. 9–10. Those proposed constructions are consistent with the lexicographic definition provided in the ’002 patent. In a section titled “Definitions,” the ’002 patent states: The term “pre-installed generic driver” is intended to mean a driver which is installed on a processing device such as a computer as a standard driver, e.g. is installed with the installation of the operating system. Such a driver is standard for the operating system and can drive a standard class of peripheral devices coupled to or connected to the processing device. Ex. 1001, 14:32–38.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“Patent Owner’s arguments are unpersuasive. We are not persuaded that these differences between Kaplan, Ahmed, and Deforche are dispositive. To the contrary, we find the differences establish why a POSITA would have further modified Kaplan and Ahmed with the teachings of Deforche. Deforche expressly teaches that a disadvantage of wireless modems is that they require installation of an appropriate driver before applications running on the computer device can use the functionality of the wireless modem to connect to wireless networks. Ex. 1030 ¶¶ 2–3. 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. Any need or problem known in the field of endeavor at the time of and addressed by the patent can provide a reason for combining the elements in the manner claimed.” Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1379 (Fed. Cir. 2023) (internal quotations omitted). As the Federal Circuit held, “[t]here is a motivation to combine when a known technique has been used to improve one device, and a [skilled artisan] would recognize that it would improve similar devices in the same way.” Intel Corp., 61 F.4th at 1380. Here, Deforche establishes that utilizing an operating system’s preinstalled generic driver to provide a generic protocol communications between the processing device and a peripheral device was known for improving wireless modems because it does not require administrator rights and a specific driver to be installed to enable communications between the wireless modem device and the processing device.” slip op. at 20
