“processor” to the spare processor, we determine that the claim is describing this transfer of identification of “boot processor,” which is required when transferring a boot processor’s functions to a spare because of the “problems [that] arise in attempting to idle (or eject) the boot processor.” Id. at 6:25– 27. This is confirmed by the language of limitation [1d], stating that the switching of the role of boot processor involves “changing a system identifier of the spare processor to that of the boot processor.” Thus, the firmware and operating system exchange this information identifying the boot processor, which is described in the specification as a device tree. See, e.g., id. at 13:21–35. The ’302 patent makes clear that accurate identification of which processor is the boot processor remains critical during runtime. See, e.g., id. at 6:25–27. Thus, Patent Owner is correct in requiring the system to have a way to identify the boot processor and to transfer this identification during runtime. However, as made clear in the embodiments described in the ’302 patent discussed above, this identification is for runtime purposes to accommodate runtime problems, not for booting purposes. Although Patent Owner may be correct that a function of the boot processor is to boot the system (PO Sur-reply 5), the problem identified in the ’302 patent is a problem relating to the runtime reassignment of the boot processor identity, to address a runtime need to identify the boot processor. See, e.g., Ex. 1001, 11:6–9. Accordingly, based on our analysis of the claims and specification, we determine that “switching the role of boot processor to a spare processor without shutting down the system’s operating system” means causing the system to identify the spare processor as the boot processor (e.g., in a device tree), which then causes the spare processor to appear as the boot processor to the system during runtime. Ex. 1001, 6:25–41, 11:4–18 (describing why boot processors are treated differently even after the boot process has completed); compare id. at 9:65–11:3 (process for recovering from loss of lockstep of a non-boot processor without using a spare), with id. at 11:4–43 (process for recovering from loss of lockstep of a boot processor using a spare because boot processors, during runtime, need special treatment); see also 14:66–15:21 (emphasizing that spares are only needed for recovering boot processors). We construe switching a “role of boot processor” to mean transferring an identification in the system of which processor is the boot processor. This construction comports with the embodiments described in the specification. We do not adopt an additional requirement that this procedure also requires designating which processor will boot the system in the next reboot, which is not disclosed in the specification.” slip op. at 24

“may swap processors that are failing, and perform the necessary bookkeeping to keep the operating system informed as to how to address the processors available, nothing in the Petition persuasively explains whether this generic processor swapping switches the boot processor role. As we explained in our claim construction section, the term “boot processor” is not merely a label of convenience to describe the processor that happened to have earlier booted the system. The role of boot processor is specifically switched to the spare; it is a piece of information tracked by the system. As we explain below, Petitioner does not adequately address the transfer of this information to make the system aware of which processor has the boot processor role. Petitioner asserts that “the BSP flag” of the IA-32 system is used to “determine whether a processor is the boot processor.” Pet. 17–18. Petitioner here is relying on a register used in IA-32 processors to identify whether or not they are the boot processor. This register is used during booting so that only the boot processor boots the system. See, e.g., Ex. 1008, 238–40, 710. This register does not appear to serve any further role, and Petitioner offers no persuasive evidence or argument that the processor register flag is exposed or copied to the operating system or APIC table. Petitioner’s proposed combination does not involve updating this register, nor does Petitioner explain how, even if the register were updated, it would meet the “switching” a “role of boot processor” in limitation [1d].” slip op. at 32

“whether they are the boot processor or not (Ex. 1008, 238, 710), Petitioner does not explain how such information is exposed to the BIOS or operating system, nor how it is changed during runtime, after its purpose has been fulfilled. In sum, even if Petitioner’s proposed combination swaps the spare processor for the processor that booted the system, Petitioner’s proposed combination does not appear to transfer the role of boot processor to the spare processor. At best, Petitioner’s proposed combination transfers the tasks of one processor to another.

There is no reason why one version of the hardware used to emulate the RFID function could not be RFID transponder circuitry. The issue is not whether an RFID transponder can emulate itself, but rather whether RFID transponder circuitry incorporated into a mobile communications device can be used to allow the mobile communications device to emulate a separate RFID transponder. For example, rather than requiring the person described in the Background of the ’947 patent to carry both a mobile phone and a “key with remote control for gaining access to his/her vehicle,” they need only carry the mobile communications device of the claims. The statement in the ’947 patent that “the present invention is related to an emulated radio frequency data input method” (Ex. 1001, 1:22–24), and the other references to emulation, are consistent with a conclusion that the claims encompass the “functional emulation” option as described above.

“Patent Owner “disputes the narrow range of educational experiences in the Petition’s POSITA definition, but does not otherwise dispute the remaining portion of the definition.” PO Resp. 12. Patent Owner contends that person of ordinary skill in the art: [W]ould have been someone “with at least a Bachelor’s degree in Electrical Engineering, Computer Science, or a related field, with a background in radio frequency communications and software development, as well as approximately two years of experience working with or researching radio frequency communication systems. Lack of work experience can be remedied by additional education, and vice versa.” PO Resp. 12 (citing Ex. 2004 ¶ 34).7 Based on a review of the record, we adopt Patent Owner’s proposed level of ordinary skill in the art, with its inclusion of a Computer Science background, because it is consistent with the evidence of record, including the asserted prior art and ’974 patent specification.

“We agree with Patent Owner’s description of the characteristics and operation of a wireless mobile phone, which are not in dispute. Also, the Specification’s description of wireless mobile phones is relied on by Patent Owner in its arguments regarding the construction of “voice call signal,” as discussed below. Nonetheless, Petitioner argues that it is unnecessary to construe the term, “wireless mobile phone.” Reply 4. We agree. The term “wireless mobile phone” is only used in dependent claim 19 (not in independent claim 12, as Patent Owner alleges), and the principal reference relied on by Petitioner (Willgert) explicitly discloses the use of a mobile telephone. Ex. 1001, 12:2; Ex. 1004 ¶¶ 30–32. For these reasons, and because our analysis of the issues set forth below is not dependent on Patent Owner’s proposed construction, it is unnecessary to adopt Patent Owner’s construction or otherwise construe the term “wireless mobile phone.”” slip op. at 12

“to an emulated radio frequency data input method” (Ex. 1001, 1:20–21), and the other references to emulation, are consistent with a conclusion that the claims encompass the “functional emulation” option as described above. However, there is no basis for adding the negative limitation proposed by Patent Owner (“without the use of a physical RFID transponder”). Omega Engineering, 334 F.3d at 1333 (rejecting a construction because “neither the plain text of the claims, the specification, nor the file wrapper justifies the imposition of this negative limitation”). See also BillJCo, LLC v. Apple Inc., No. 2023-2189, 2023-2190, 2025 WL 1417957, at *1 (Fed. Cir. May 16, 2025): Our court has “identified claim constructions that exclude a particular element as including a ‘negative limitation’ and held that such exclusions must find support either in ‘the words of the claim’ or through an ‘express disclaimer or independent lexicography in the written description that would justify adding that negative limitation.’” Ethicon LLC v. Intuitive Surgical, Inc., 847 F. App’x 901, 907 (Fed. Cir. 2021). Patent Owner’s argument that the claim language, “[a] transceiver . . . configured to output . . . RFID transponder [signals or data],” only makes sense “if the transceiver is not itself an RFID transponder” (Sur-Reply 10) is not persuasive. Examination of the complete version of the passage that Patent Owner only paraphrases — “[a] transceiver configured to output voice call signals in the first state and to output RFID transponder signals in the second state” — shows that the transceiver is capable of both voice call and RFID functions, and thus there is no inconsistency in allowing the RFID function to be performed by RFID transponder circuitry incorporated into the transceiver.” slip op. at 24

“Petitioner argues that this combination would have been motivated by the fact that Willgert teaches that integrating its communications unit into a mobile telephone designed for Bluetooth communication was a “highly user-friendly application,” and that it was well known practice to use a Bluetooth headset wirelessly communicating with the phone to enable hands-free phone calls, as specifically taught by Mooney.

“image capture device” refers to an imaging-based barcode reader and not a laser-based barcode scanner because we are persuaded that claim language and Specification support that interpretation and also because Patent Owner persuasively shows that a person of ordinary skill in the art would have understood the term as such. Claim 1 recites an “image capture device configured to capture an image.” Ex. 1001, 16:24–25. The plain meaning of the claim term requires that the image be captured, not just scanned. The claim further requires “generating an output based on the information embedded in the image,” requiring that information is retrieved from the captured image. Id. at 16:32–33. A device that does not capture an image is not an “image capture device” under the plain language of the claim. A laser-based barcode scanner employs light reflected from a laser beam to “generate an electrical signal that corresponds to the bars and spaces in the barcode being scanned.” See Ex. 2029 ¶¶ 42–43 (explaining in detail how laser-based barcode self-emitting a laser light across a code to be scanned, with a sensor tuned to capture the reflected light from the laser.”).

“We agree with Patent Owner that Wang fails to disclose limitation 1[a]. Wang discloses a portable electronic authorization device (PEAD) that can be used as a self-checkout terminal. Ex. 1004 ¶ 115. In this context, Wang discloses By entering the UPC code or barcode using keypad on the PEAD or scanning in the UPC code or barcode using the input device built into the PEAD such as a barcode scanner or OCR reader, the PEAD can generate the receipt with the list of item prices through the wireless network and Internet by querying the item price using the barcode as the index for price lookup table which is Stored in a Server System. Id. (emphasis added). As discussed above (Section III.C.1), we are persuaded by Patent Owner’s arguments that the claimed “image capture device” refers to an imaging-based device and not a laser-based barcode scanner. Petitioner does not contend that Wang’s disclosure of the barcode scanner necessarily refers to an imaging-based device, but argues that Wang’s disclosure is sufficient because “both imaging-based barcode scanners and laser-based barcode scanners constitute image capture devices.” Reply 11.

Drummond Drummond is a patent titled “Automated Banking Machine System and Method,” and “relates to an automated banking machine apparatus and system that are capable of use in a wide area network, and which provides a user with a remote electronic receipt or other record related to a transaction performed at the machine.” Ex. 1008, code (54), ¶ 2. Drummond discloses that its automated banking machine, may “initiate the sending of a non-paper transaction receipt to the customer,” “[t]he receipt may be sent using a wide area network, such as the Internet,” and “[t]he receipt may be an electronic receipt, for example a receipt in the form of an e-mail message.” Id. ¶ 247. 2. Claims 1, 4, 5, 7, 12, 17, 23, 26, 27, 29, 34, and 43 For this obviousness ground, Petitioner relies on the same arguments and evidence as its Ground 1a (anticipation by Wang), discussed above, for the majority of claim limitations.
