    “In response, we conclude that the most natural reading of limitation [l] results from examination of the entire limitation: “locating encryption information that identifies encrypted portions of frames of video within the requested portions of the selected stream of protected video.” Ex. 1001, 27:54–57. The “within” most naturally connotes where the encrypted portions of frames of video occur, as opposed to determining where the encryption information may be located. Patent Owner’s interpretation is not wrong, i.e., the limitation could be read as Patent Owner suggests, leading to a narrower construction, but we are not persuaded that the construction of limitation [l] must be so limited, on the basis of the words themselves. We continue to reject Patent Owner’s interpretation that limitation [l] requires locating encryption information within the requested portions of the selected stream of protected video. See Inst. Dec. 27–30; 1st Final Dec. 8. Although it is apparent that encryption information can be found within the requested portions, we are not persuaded that the claim language or ’588 Patent implicitly or explicitly requires such a relationship. Likewise, although embodiments disclosed in the Specification of the ’588 Patent are consistent with Patent Owner’s more restrictive construction, the Specification also is consistent with the more grammatically correct construction as well. Thus, we construe limitation [l] as requiring that the encrypted portions of frames of video be within the requested portions of the selected stream of protected video, but we do not construe limitation [l] as requiring that the encryption information be within the requested portions of the selected stream of protected video.” slip op. at 15

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.

    “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. Pet. 14–17 (citing Ex. 1004 ¶¶ 8, 30–32; Ex. 1005, Fig. 3, ¶¶ 7, 39, 46–48; Ex. 1021; Ex. 1003 ¶¶ 72–76). Petitioner further argues that Bluetooth headsets were widely available, that incorporating the headset involved known methods yielding predictable results, and that one of ordinary skill would have reasonably expected to succeed in combining the teachings of Willgert and Mooney. Id. at 17–19 (citing Ex. 1004 ¶ 10; Ex. 1005, ¶ 8; Ex. 1017, 1, 3; Ex. 1021, 2; Ex. 1003 ¶¶ 77–79). Patent Owner does not specifically address the issue of motivation to combine Willgert and Mooney. See generally PO Resp. We find, based on the record, that Petitioner has proved by a preponderance of the evidence that a person of ordinary skill in the art would have been motivated to combine Willgert and Mooney as proffered by Petitioner with a reasonable expectation of success.” slip op. at 31

    “with Chishti-876’s purported teaching away and disparagement, we note again that “round-tripping” is defined in the Specification as “the technique of moving a first tooth out of the path of a second tooth, and once the second tooth has moved sufficiently, moving the first tooth back to its previous position before proceeding to a desired final position of that first tooth.” Ex. 1001, 13:8–12. Chishti-876 teaches that its “path scheduling algorithm determines the treatment path while avoiding ‘round-tripping,’ i.e., while avoiding moving a tooth along a distance greater than absolutely necessary to straighten the teeth. Such motion is highly undesirable, and has potential negative effects on the patient.” Ex. 1005, 14:46–51. The Petition does not expressly address this teaching in Chishti-876, nor does it address the prior Board finding in the ’444 IPR, in which the Board recognized that this teaching constitutes a teaching away from round-tripping. See Ex. 1008, 11– 12. On this record, it appears that Chishti-876 teaches away from “moving a tooth along a distance greater than absolutely necessary to straighten the teeth.” In short, Chishti-876 disparages “moving a tooth along a distance greater than absolutely necessary to straighten the teeth” (Ex. 1005, 14:46– 51) which is a broad statement that appears to encompass the more specific round-tripping movement taught in Becker. Petitioner itself concedes that “indirect movement was understood to be avoided if possible.” Pet. 17. Although Petitioner attempts to characterize indirect movement or round-tripping as a preferable or necessary option (see, e.g., Pet. 15–17), these arguments are insufficiently supported on this record.” slip op. at 27

    “if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. 35 U.S.C. § 103(a); see also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved based on underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) any objective indicia of nonobviousness.7 Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). An obviousness determination requires finding a reason to combine accompanied by a reasonable expectation of achieving what is claimed in the challenged patent. See Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1367 (Fed.

    “tripping” as “any motion of a tooth in any direction other than directly toward the desired final position.” Ex. 1004, 4:12–13. Chishti-511 teaches minimizing round-tripping (“teeth are moved in the quickest fashion with the least amount of round-tripping”), but acknowledges that “[r]ound-tripping is sometimes necessary to allow teeth to move past each other.” Id. at 4:9–15. In an attempt to counter Patent Owner’s teaching away arguments, Petitioner relies heavily on Chishti-511’s statement that “[r]ound[-]tripping is sometimes necessary.” See Pet. 29–30; see also Ex. 1003 ¶ 83 (Dr. Yadav relying on Chishti-511). This reliance is unavailing, because as noted above, Chishti-511 defines “round-tripping” more broadly than is claimed here. Indeed, in the ’444 IPR, the Board stated that “the ‘round tripping’ described in Chishti ’511 is something different than the ‘round tripping’ required by the ’444 patent.”10 Ex. 1008, 16. Despite being aware of this prior finding 10 In the ’444 IPR, the Board employed the same construction of “round-tripping” that we use here. Compare Ex. 1008, 6, with Section II.C supra. (see Pet. 6), Petitioner here fails to address the difference between Chishti- 511’s round-tripping and the claimed round-tripping. That is, Petitioner places great weight on Chishti-511’s statement that “round-tripping is sometimes necessary,” but has not established that Chishti-511 contemplates round-tripping as claimed, as opposed to some other, different movement pattern encompassed by Chishti-511’s broader statement about round-tripping.” slip op. at 21

    “discussion of “need[ing] collision-free treatment paths,” skilled artisans would have turned to Becker. Pet. 23–24 (citing Ex. 1004, 4:15–22). But on this record, and especially in view of the teachings away from round-tripping, Petitioner does not demonstrate a reasonable likelihood that a skilled artisan would have combined Becker’s movement pattern with the Chishti systems and Sachdeva. In particular, the Petition and supporting materials lack sufficient argument and evidence for us to conclude that a person of ordinary skill in the art would have had reason to apply Becker’s movement pattern in the context of an aligner treatment. Becker is a textbook relating to the orthodontic treatment of impacted teeth. Ex. 1006, 1 (Title). Patent Owner correctly states that “Becker is a different orthodontic treatment modality compared to the Chishti references,” using “braces and numerous brackets, wires, and rubber bands, with the wire-and-bracket systems being attached directly and permanently to the teeth.” Prelim. Resp. 21–22; see also supra Section II.D.4. “Becker involves traditional orthodontic practice: manual, by-eye adjustment of its archwires, elastic thread, and palatal wires by a treating orthodontist in repeated office visits.” Prelim. Resp. 22. Chishti-511, in contrast, uses “treatment planning software” to “pre-stag[e] a series of tooth positions from which a sequence of appliances can be manufactured.” Id. On this record, we agree with Patent Owner that “Becker at best shows that round-tripping was an option in limited circumstances involving wire-and-bracket treatment.” See Prelim. Resp. 3. Petitioner does not direct us to any persuasive evidence that using aligners to effect Becker’s tooth transposition “would be appropriate or even possible.” Id. at 22. As Patent Owner correctly notes, Petitioner does not point to any teaching in Becker regarding aligner treatment or corresponding treatment planning software. Id. at 23. Nor are we directed to any portions of Chishti-511, Chishti-876, or Sachdeva that mention using aligners to transpose teeth. These omissions are important because “[i]n contrast to treatment with braces, in which wires are manually adjusted by the orthodontist to move teeth reactively, aligner treatment involves treatment planning in which a detailed path of teeth is calculated in advance.” Id. at 4. Given these differences, Petitioner has not persuasively explained why Becker’s tooth movement pattern and mechanism would have been of interest to a skilled artisan who was” slip op. at 25
