A claim is unpatentable under 35 U.S.C. § 103 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 the subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of 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 skill in the art; and (4) if in evidence, so-called secondary considerations.

“We do not agree with Petitioner that the fact pattern before us is analogous to Rembrandt. The rationale to combine the teachings of Inoue and Smith provided in the Petition focuses on replacing incandescent bulbs with LEDs, and includes the generic statement that “[t]he numerous record-supported advantages, set forth in Smith provide a clear motivation for use of the teachings of Smith as applied to Inoue, so as to enjoy the advantages set forth in Smith.” Pet. 47. The testimony in Dr. Schubert’s Declaration at pages 99–100 cited in support of Petitioner’s Reply arguments was not cited or otherwise referenced in the Petition. See Pet. 46–55. We find that the Petitioner’s Reply is not responsive to the Institution Decision and is improper because it presents a new rationale to combine the teachings of Inoue and Smith that was not expressed in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Petitioner could have presented its rationale to make out a prima facie case of unpatentability in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Accordingly, we do not consider Petitioner’s new rationale to combine the teachings of Inoue and Smith presented for the first time in the Reply. Based on the entire record, but not including Petitioner’s new rationale and newly cited support to Smith and Dr. Schubert’s testimony (Exs. 1013, 1017) presented for the first time in the Reply, we are not persuaded that Petitioner sets forth in the Petition sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to modify the circuit of Inoue to include a light source or LED light source with a twinkling or flashing effect in view of Smith’s teachings. See Pet. 46–47, 49–50, 51–53, 55. Accordingly, we determine that Petitioner has not demonstrated by a preponderance of the evidence that the subject matter of independent claim 9 and dependent claims 3, 5, and 6 would have been obvious over the teachings of Inoue and Smith.” slip op. at 32

“Based on Petitioner’s citations to Holler, Inoue, and Dr. Schubert’s testimony (Ex. 1013), we are persuaded Petitioner sets forth sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to “use the resistive value as taught by Holler in the circuit of Inoue to control the illumination of the light sources so that the other illumination devices in the serial light string will not go dark or change illumination if one of the LEDs fails or becomes disconnected.” Pet. 27; see KSR, 550 U.S. at 418. Based on the entire record and including the reasons explained above in Section II.D.2. addressing anticipation of claim 1 by Inoue, we determine Petitioner shows by a preponderance of the evidence that the subject matter of claims 1 and 10 would have been obvious over Inoue and Holler.

“We observe that, aside from Declaration testimony of Mr. Altamura and accompanying exhibits, Patent Owner does not offer any additional evidence to establish reduction to practice. An inventor’s testimonial assertion of inventive facts requires corroboration by independent evidence. Brown v. Barbacid, 276 F.3d 1327, 1335 (Fed. Cir. 2002). The purpose of the corroboration requirement is to prevent fraud, by providing independent confirmation of the inventor’s testimony. Kridl v. McCormick, 105 F.3d 1446, 1450 (Fed. Cir. 1997). Without the requirement of independent corroboration, there would be a great temptation to commit perjury and the adverse party would be effectively precluded from a successful rebuttal. Price v. Symsek, 988 F.2d 1187, 1194–95 (Fed. Cir. 1993). A rule of reason applies to determining whether the inventor’s testimony has been corroborated. See id. at 1195. “The rule of reason, however, does not dispense with the requirement for some evidence of independent corroboration.” Coleman v. Dines, 754 F.2d 353, 360 (Fed. Cir. 1985). Accordingly, based on the entire record, we find that Mr. Altamura’s Declaration testimony is uncorroborated. Yu is prior art to the ’252 Patent because Patent Owner is unable to establish actual reduction to practice earlier than the July 31, 2006, filing date of Yu.” slip op. at 51

“On this record, we determine that the recitation “to achieve continuous presentation” is limiting and requires an amount of continuous (uninterrupted) playback/presentation after an upshift or downshift. The specification describes agent controller 702 determining whether to upshift based on a trigger threshold Θup, which itself is based on various factors including a current read ahead margin and a minimum safety margin. See Ex. 1001, 17:44–58. If agent controller 702 can sustain upshift quality, then it will upshift and request higher quality streams. See id. at 17:58–61. Conversely, when an upshift is not possible, agent controller 702 determines whether to downshift based a different threshold Θdown, which itself is based on the same sort of factors. See id. at 18:4–7. When the stream quality is not adequate, it downshifts. See id. at 18:7–14. These disclosures are similar to the language of claim 12, which recites “repeatedly generating a factor indicative of a current ability to receive the digital content at a rate sufficient for presenting the digital content as the digital content is received, . . . wherein the factor relates to a performance of the network” and “making the successive determinations whether to change the requested bit rate based on the factor to achieve continuous presentation of the digital content using the individually-requestable portions of the highest bit rate one of the copies determined receivable at that time.” Ex. 1001, 20:5–16 (emphasis added). That is, claim 12 refers to “achiev[ing] continuous presentation” based on what is “sufficient for presenting the digital content,” trading quality to ensure continuous playback.” slip op. at 14

“server comprises at least two servers and wherein at least one streamlet is requested from a first of the at least one server and at least one other streamlet is requested from a second server of the at least one server other than the first server.” Ex. 1001, 19:7–12. Petitioner references its mapping of the “at least one server” in claim 1 to Leaning’s server 1. Pet. 20 (citing Ex. 1004, 2:15–16, 2:18–22, 2:31–32, 5:8–14, Fig. 1), 23 (citing Ex. 1004, 6:13–26, 9:3–7, 16:6–12), 37; see supra §§ II.D.2.b–c. Petitioner contends that, “[t]o the extent Leaning does not disclose at least two servers wherein one sub-file (streamlet) is requested from a first server and another sub-file (streamlet) is requested from a second server such an arrangement would have been obvious in view of the knowledge of a [an ordinarily skilled artisan].” Id. at 37. Citing the common nature of such an arrangement, Petitioner contends that an ordinarily skilled artisan would have been motivated to provide multiple web servers containing the same sets of sub-files for streams in order to have redundancy in the system and allow for clients to establish connections with multiple servers and request a first sub-file from a first web server and, if the connection between the first web server becomes congested or the first web server otherwise fails or becomes unavailable, request a subsequent sub-file from the second web server. Id. at 37–38 (citing Ex. 1003 ¶ 85; Ex. 1012, 108,5 Fig. 4-11). Patent Owner does not dispute Petitioner’s analysis for claim 3. We are persuaded that it would have been obvious to implement Leaning’s server 1 as two servers that store different streamlets based on Dr. Houh’s uncontested testimony about system redundancy. See Ex. 1003 ¶ 85. His testimony is backed by a contemporaneous reference about HTTP that shows requests for different objects from different servers over parallel TCP connections. See, e.g., Ex. 1012, 108–09, Fig. 4-11. Thus, we determine that Petitioner has shown, by a preponderance of the evidence, that the subject matter of claim 3 would have been obvious over Leaning.” slip op. at 34

“Patent Owner does not address the level of skill. See Prelim. Resp.

If a different level of skill would affect the outcome in this case, the parties must brief that issue as well. The failure of Patent Owner to describe how a different level of skill in the art is determinative will be a forfeiture of that argument. If there is a dispute regarding the level of ordinary skill in the art, then the parties are also encouraged to submit evidence, other than conclusory expert testimony, that supports their position.

See PO Resp. 8–9. It is well settled that it is improper to read an extraneous limitation into a claim from the specification. See e.g., Commark Comm’s Inc. v. Harris Corp., 156 F.2d 1182, 1186 (Fed.

“3. “Inherent Resistance” Claim 10 uses the term “inherent resistance of the light source to which the light resistor is attached.” See Ex. 1001, 14:46–48. Petitioner asserts that “there is no ‘inherent resistance’ of an LED, but only the resistance of the LED at any particular operating current flowing through, and voltage across, the LED.” Pet. 21 (citing Ex. 1013, 29 ¶¶ 6–9). Petitioner also points out that the term inherent is not used in the ’794 Patent Specification. See id. Patent Owner does not explicitly address “inherent resistance” in terms of a claim construction. See Prelim. Resp. 6–9. In any event, when addressing an alleged lack of motivation to combine the teachings of the references, Patent Owner compares and contrasts incandescent bulbs, which according to Patent Owner, have an inherent resistance, and LEDs, which according to Patent Owner, do not exhibit self-regulating resistance. See Prelim. Resp. 20 (citing Ex. 2002 ¶ 67); see also id. at 23 (similar argument, citing Ex. 2002 ¶ 73). Indeed, Patent Owner asserts that “the word resistance is not useful when describing LEDs as opposed to incandescent bulbs. . . . LED lights have an exponential current vs. voltage relationship . . . rather than a linear current vs. voltage relationship as found in a simple resistance, such as seen in incandescent light bulbs.” Id. at 20 (citing Ex. 2002 ¶ 66). For the purpose of institution, we understand the term “inherent resistance” to mean the resistance at a particular operating current or voltage across the LED light source.

“Conclusion as to Claim 1 Based on the present record, Petitioner has not shown sufficiently that Havewala teaches at least the following limitations of claim 1: 1. “intercepting the request by a software client on the first device;” and 2. “determining by the software client if the file is physically located on the first device or if the file is a virtual file of a corresponding file physically stored on a second device by reviewing file metadata.” Petitioner does not identify any teachings from Adams that bear on these limitations. Therefore, Petitioner does not demonstrate a reasonable likelihood of success that it would prevail in showing that claim 1 is unpatentable.” slip op. at 24

“At this juncture, the parties only appear to dispute the educational background in the definition of the level of ordinary skill in the art. The only evidence in the present record regarding the educational background consists of Dr. McDaniel’s declarations in this case and in the underlying litigation. See Ex. 1003 ¶ 21; Ex. 2001, 14–15. We agree with Patent Owner that both of these declarations support that a person of ordinary skill in the art would have had either a bachelor’s or a master’s degree in computer science or electrical engineering or a related degree. Prelim. Resp. 2–3. Moreover, Petitioner does not explain why a master’s degree is necessary. Thus, we revise Petitioner’s proposed definition to conform to Dr. McDaniel’s testimony. We additionally remove the qualifier “at least” from Petitioner’s proposed definition, because this qualifier introduces ambiguity. Thus, for purposes of this Decision, we apply the following definition of the level of ordinary skill in the art: a POSITA would have been a person holding a bachelor’s degree or a master’s degree in computer science or electrical engineering or a related degree, with two years of training or experience with networking and file systems. This definition appears to be consistent with what is reflected by the content of the applied prior art references as well. Cf. Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (the applied prior art may reflect an appropriate level of skill). We note, however, that our analysis below would not change even if we adopted Petitioner’s definition as stated in the Petition.” slip op. at 10

“The instant limitation recites “intercepting the request,” which relies for its antecedent basis on the “accepting a request” limitation recited above. Therefore, this claim requires that the same “request” be both accepted and intercepted. See Baldwin Graphic Sys., Inc. v. Siebert, Inc., 512 F.3d 1338, 1342–43 (Fed. Cir. 2008) (noting that definite articles such as “the” and “said” create anaphoric phrases that refer to the initial antecedent phrase, and do not alter the meaning of the antecedent “in the slightest”). Petitioner, however, fails to identify any “request” that is both “accepted” and limitation, Petitioner relies on the “open” message sent to the file system as the recited “request” that is accepted. Id. at 20–22. For the “intercepting the request” limitation, however, Petitioner relies on an error message sent back from the file system to the application as the recited “request” that is intercepted. Id. at 33. Thus, Petitioner points to two different features of Havewala for teaching the same required “request” in claim 1. This is fatally inconsistent. Therefore, Petitioner fails to adequately demonstrate that Havewala teaches that the same “request” is first accepted and then intercepted, as required by the claim. Even were we to overlook the inconsistency in Petitioner’s analysis, Petitioner still fails to establish that Havewala teaches the claimed “request to operate on a file.” Petitioner relies for this limitation on an error message generated by the file system as the claimed “request.” Pet. 33. This error message, however, is not a “request to operate on a file,” as claimed. This error message is instead a response generated by the file system to a request from the application or operating system to open a file. Ex. 1005 ¶ 64. The response indicates that the request cannot be fulfilled because the target file has no data. Id. Havewala discusses its messaging paradigm with reference to Figure 6, which is excerpted below: steps performed in reconstituting a ghosted file from the sink. See Ex. 1005 ¶ 27. This excerpt depicts steps 601, 603, and 605. At step 601, the file system 16 receives an open command from an application 30. Id. ¶ 67. In this step, the “file system . . . notes that the ghosted file 14 does not contain the removed data 20.” Id. ¶ 68. Then, after the open command has already been received and processed by Havewala’s file system, the file system returns an error at step 603. Id. at Fig. 6. This “returned error” is what is intercepted by the ghosting filter 26, at step 605. Id. ¶ 68, Fig. 6. Figure 6 of Havewala and the associated text at paragraphs 67 and 68 demonstrate that the error message that is intercepted by Havewala’s ghosting filter is not a request; instead, it is a response to the “open” request. Petitioner’s argument that an error message is the claimed “request” is therefore unsupported by the evidence of record.” slip op. at 17

- Novelty / Anticipation (§102) › Anticipation standard (single reference, every element) › Inherent disclosureInherency foundInstituted
“We understand Petitioner to rely on an inherent disclosure of the certainty score in contending that Korten anticipates claim 1. See, e.g., ABS Glob., Inc. v. Cytonome/St, LLC, 84 F.4th 1034, 1042–43 (Fed. Cir. 2023) (“A claim is anticipated if ‘each and every element as set forth in the claim is found, either expressly or inherently, in a single prior art reference.’” (emphasis added). And inherency is a high standard. See, e.g., Cont’l Can Co. USA v. Monsanto Co., 948 F.2d 1264, 1269 (Fed. Cir. 1991) (“Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient. If, however, the disclosure is sufficient to show that the natural result flowing from the operation as taught would result in the performance of the questioned function, it seems to be well settled that the disclosure should be regarded as sufficient.”). We determine, on the limited record before us, that Petitioner has made a sufficient showing for institution that a certainty score would naturally flow from Korten’s validity and error determinations. Accordingly, upon review of the information in the Petition and corresponding evidence, including Patent Owner’s counter arguments, we determine Petitioner has sufficiently demonstrated, at this stage of the proceeding, that Korten discloses the subject matter of limitation 1[c].” slip op. at 24

“teachings of Korten with either Lehmann I or Lehmann II. Prelim. Resp. 22–26, 29 (referencing arguments for Ground 2), 35–36 (referencing arguments for Ground 2 directed to motivation to combine references). Patent Owner argues that, contrary to Petitioner’s assertion, the technology of Korten does not overlap with Lehmann II. Id. at 23. Specifically, Patent Owner argues that Petitioner and Dr. Foroosh fail to address how a person having ordinary skill in the art could have successfully combined the two-dimensional imaging of Lehmann II with the three-dimensional imaging of Korten. See id.; see, e.g., Pet. 31 (“Lehmann II is directed towards the analysis of [two-dimensional] images, whereas Korten is directed towards rendering and displaying [three-dimensional] models.”). Patent Owner argues that Petitioner should have been aware of this issue given the Board’s prior decision denying institution in IPR2023-00400. Prelim. Resp. 23. Patent Owner then itemizes a list of technical challenges with respect to combining a two-dimensional system with a three-dimensional system. Id. at 24. These challenges include that Petitioner does not explain “how one might associate a Z-coordinate of Korten with the color data obtained by the Lehmann II camera,” how a person having ordinary skill in the art “would have Korten’s processor align the [two-dimensional] color image areas obtained by the Lehmann II camera with the [three-dimensional] entity previously created by Korten, and then provide color values to the entity at aligned X-Y-Z points,” and “how to implement Lehmann II’s [two-dimensional] image into Korten’s [three-dimensional] model.” Id.; see also id. at 24–26 (discussing difficulties in using spectrophotometers to collect color data and associating two-dimensional color data with three-dimensional representations). Petitioner, concentrating on Lehmann II’s best fit technology, contends that “[a]lthough Lehmann II is directed towards the analysis of [two-dimensional] images, whereas Korten is directed towards rendering and displaying [three-dimensional] models, this difference is immaterial as it relates to determining the certainty score of the selected tooth shade value.” Pet. 31 (referencing Ex. 1015 ¶ 141); cf. Ex. 1015 ¶ 141 (providing the same testimony as is in the Petition). We have reviewed Patent Owner’s argument and determine, on the limited record before us, that Patent Owner identifies a weakness in Petitioner’s position. Petitioner’s contentions concerning motivation to combine Korten and Lehmann II seem to focus on a motivation for using Lehmann’s teachings of the subject matter of limitation 1[c], and does not address Petitioner’s reliance on Lehmann II for the subject matter of limitation 1[b], which recites the step of “determining a tooth shade value for at least one point on the tooth based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.” See Pet. 30 (mapping the requirements of limitation 1[b] to disclosures in Lehmann II); Ex. 1001, 21:33–37 (providing limitation 1[b]). Limitation 1[b] seems to require implementing teachings concerning two-dimensional color data from Lehmann II with three-dimensional color data collected at the step of limitation 1[a] by Korten’s system. As such, Petitioner’s reasoning may not be adequately supported by a rational underpinning. Cf. KSR Int’l Co., 550 U.S. at 418 (stating that, to facilitate the analysis of an obviousness position, the proponent should provide “some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”).
