    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Decided for petitioner

      “A district court stay of the litigation pending resolution of the PTAB trial allays concerns about inefficiency and duplication of efforts.” Fintiv Order 6. That is the case here. Thus, the first Fintiv factor strongly weighs against exercising the authority to deny institution. Id. Under the second Fintiv factor, the proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision weighs against exercising our authority to deny institution because there is no trial date scheduled. Id. at 9; see Ex. 1031, 3. slip op. at 8

    • PTAB / AIA Trials › Institution threshold (reasonable likelihood / more likely than not)InstitutedInstituted

      “To institute an inter partes review, we must determine “that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a). The Board, however, has discretion to deny a petition even when a petitioner meets that threshold. Id.; see, e.g., Cuozzo Speed Techs., LLC v. Lee, 136 S. Ct. 2131, 2140 (2016) (“[T]he agency’s decision to deny a petition is a matter committed to the Patent Office’s discretion.”). For the reasons that follow, we grant institution of inter partes review.” slip op. at 2

      “have a bachelor’s or equivalent degree in computer science or a related field and at least 2 years of experience in multimedia processing or delivery using internet protocols.” Pet. 10 (citing Ex. 1002 ¶¶ 67–68). Petitioner further states that “a person with less formal education but more experience, or more formal education but less experience, could have also met the relevant standard for a POSITA.” Id. Patent Owner submits a similar definition (see Prelim. Resp. 13–14), but states that a POSITA “would understand that . . . the subject of the patent is a software-based solution to broadcasting multimedia streams, and the skillset and expertise in hardware-based systems would not make one knowledgeable about software-based systems.” Prelim. Resp. 13–14. We determine that no express finding is necessary, on the present record, and that the level of ordinary skill in the art is reflected by the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978). The difference in how each party characterizes a POSITA’s work experience does not change our analysis or conclusions based on the present record. Should Patent Owner dispute Petitioner’s definition during trial, we encourage Patent Owner to explain how a software-focused definition would affect any obviousness analysis in our final written decision.” slip op. at 10

      “B. Merits 1. Level of Ordinary Skill in the Art According to the Petition, Here, a Person of Ordinary Skill in the Art (“POSITA”) at the time of the claimed invention would have a bachelor’s or equivalent degree in computer science or a related field and at least 2 years of experience in multimedia processing or delivery using internet protocols. . . . A person with less formal education but more experience, or more formal education but less experience, could also meet the standard. Pet. 19 (citing Ex. 1007 ¶¶ 68–69). Patent Owner provides a different definition: A person of ordinary skill in the art at the time of the inventions in the ‘002 Patent would have had a bachelor’s degree in computer science or a related field, and at least two years of experience working in the field of software systems used in generating and broadcasting multimedia streams. An individual with less technical education but more experience, or vice versa, could also qualify as a person of ordinary skill in the art. Prelim. Resp. 12 (citing Ex. 2006 ¶ 59) (emphasis added). Patent Owner argues that the definition must include experience in software systems because the invention is a software-based solution. Id. at 12–13 (citing Ex. 2006 ¶ 60). At this stage, our decision would be the same under either definition. Should Patent Owner dispute Petitioner’s definition during trial, we encourage Patent Owner to explain how a software-focused definition would affect any obviousness analysis in our final written decision.” slip op. at 9

      “There is no dispute that (1) Avellan’s user initiates the request and eventually receives the stream and (2) gateway server 134 receives a request for a media stream for playback on a broadcast channel. See id. at 32–39; Pet. 22. The issue here is whether claim 1 requires that the recited “content provider” originates the request. We agree with Petitioner that claim 1 does not require this. Prelim. Reply 7. Apart from being received from the content provider, claim 1 does not limit the request’s origin in any way. Rather, claim 1 only requires that the request is received from the content provider. Ex. 1001, 14:51–54. Claim 1 recites “comprising” in the preamble of the method (id. at 14:50), which is a encompasses user-originated requests that are received from other entities. With this understanding of the claim, we preliminarily agree with Petitioner that Avellan discloses limitation 1a through its communication path from network 150 to user computers 1041–104n via gateway platforms 1301–130n. Pet. 22. That is, Avellan’s gateway platform 134 receives a request for at least one media stream, and claim 1 does not exclude user-originated requests. See id. We agree that the content can be video from CNN, BBC, ESPN, or other live-streaming television feeds. Id. at 24 (citing Ex. 1003, 8:18–21). Thus, at this stage and on this record, we agree with Petitioner that Avellan discloses limitation 1a. See id. at 22. ii. Remaining Limitations Apart from the arguments discussed above, Patent Owner does not present arguments specifically directed to the other limitations of claim 1. See Prelim. Resp. We determine that Petitioner’s arguments made in connection with those limitations are sufficient at this stage and on this record. Pet. 24–32. We agree with Petitioner that Avellan teaches obtaining content from the networks 150 and 152, as recited in 1b; rendering a webpage by a browser at gateway 134, as recited in 1c; generating the screen captures at gateway 134, as recited in 1d; and assembling and providing the media stream when gateway server 134 compresses the image or video format and sends it to the browser 106, as recited in 1e and 1f. Id. at 24–29. Petitioner has provided a sufficient rationale at this stage why a method with the subject matter recited in lg and 1h would have been obvious. Id. at 29– 32. Conclusion At this stage and on this record, it is reasonably likely that Petitioner would prevail in showing that claim 1 is unpatentable as obvious over Avellan. The Petition’s merits are compelling because Petitioner’s challenge plainly leads to a conclusion that claim 1 is unpatentable.” slip op. at 12

      “stipulation would only eliminate the District Court’s consideration of Haddad204. Despite the stipulation, the District Court would still have to consider invalidity of every claim the Petition addresses and would still have to consider the Alie, Baggenstoss, and Park references. Cf. Stellar at 4 (“Petitioner’s invalidity arguments in the district court are more expansive and include combinations of the prior art asserted in these proceedings with unpublished system prior art, which Petitioner’s stipulation is not likely to moot.”). In other words, “Petitioner’s stipulation does not ensure that [this proceeding] would be a ‘true alternative’ to the district court proceeding.” Id. at 3–4. Because of the remaining overlap between the Petition and the District Court proceeding, Fintiv factor four weighs strongly in favor of discretionary denial.” slip op. at 15

      “for back side illumination (BSI), which appears to teach or suggest a textured region with surface features “located on the light incident side of the semiconductor layer and configured to interact with incident [EMR].” Pet. 22–27 (citing Ex. 1006, Fig. 5, ¶¶ 53, 68, 96; Ex. 1004 ¶¶ 39–40, 88–95, 101–107). As Petitioner and its expert explain, a person of ordinary skill in the art would have been motivated to modify Figure 5 of Alie into a BSI device because BSI devices allow more incident light to reach the semiconductor layer, resulting in more light being absorbed, an increase in the quantum efficiency, and an improvement in the signal to noise ratio. Pet. 25–26 (citing Ex. 1006 ¶¶ 68, 70; Ex. 1004 ¶¶ 39–40, 92, 95). Patent Owner argues that Alie does teach, suggest, or disclose “a textured region comprising a plurality of shallow trench isolation features.” Prelim. Resp. 9–11. But it appears Petitioner has at least shown Alie teaches or suggests this element. See discussion supra. Patent Owner further argues that Petitioner fails to present any proof that a person of ordinary skill in the art would have been motivated to modify Figure 5 of Alie into a BSI device. Id. at 11–15. But, in our view, Petitioner has provided an adequate motivation to modify Alie—so that more light will be absorbed, yielding an increase in the quantum efficiency and an improvement in the signal to noise” slip op. at 18

      “B. Discretionary Denial Based on Hulu The Hulu decision held that “[b]ecause the patent claims already stand invalid, it is unnecessary to institute another proceeding to review them for patentability under other grounds.” Hulu at 2. The decision reasoned that “[i]n the event the Federal Circuit reverses the district court’s decision, Petitioner may raise such invalidity arguments in the district court on remand.” Hulu at 3 (remanding the panel’s institution decisions and denying institution). The Hulu rationale is grounded in the statutory estoppel provisions of 35 U.S.C. § 315(e) that apply only to a “final written decision;” statutory estoppel does not prevent a petitioner from raising the same invalidity grounds in district court if the petition is denied. See Intuitive Surgical, Inc. v. Ethicon LLC, 25 F.4th 1035, 1041 (Fed. Cir. 2022) decision.”). Even if inter partes review is instituted but later terminated with respect to a petitioner, e.g., after settlement, no statutory estoppel attaches to the petitioner, a real party in interest, or privy. See 35 U.S.C. § 317(a) (“If the inter partes review is terminated with respect to a petitioner under this section, no estoppel under section 315(e) shall attach to the petitioner, or to the real party in interest or privy of the petitioner, on the basis of that petitioner’s institution of that inter partes review.”). Thus, discretionary denial would not eclipse Petitioner’s ability to assert invalidity of the Challenged Claims in the District Court litigation. The Petition explains that the District Court granted a Motion to Dismiss and found all of the Challenged Claims to be patent ineligible under 35 U.S.C § 101. 130 Pet. 2 (citing Ex. 1025, 10, 14; DKR Consulting LLC v.

In the Show Cause Paper, Petitioner confirms the scope of the District Court Judgment as applying to all of the challenged claims of the ’678 and ’237 patents. See Show Cause Paper at 6 (“All challenged claims are subject to the district court’s Order and Judgment.”). All of the Challenged Claims in this proceeding having been found invalid, we see no reason to institute inter partes review.

In his supplemental declaration, Dr. Sundaresan further testifies that: I agreed with this POSITA definition when preparing the Declaration, and I continue to hold the opinion that the POSITA definition is both correct and appropriate based on the disclosures of the ’104 patent and the prior art analyzed in the Declaration. Ex. 1055 ¶ 17. Dr. Sundaresan further testifies that “[i]f I did not agree with the POSITA definition, then it would not have been included in paragraph 8 of the Declaration.” Id. ¶ 18. Dr. Sundaresan’s inclusion of the definition of the level of ordinary skill in his original declaration indicates that he agrees with the definition, as confirmed by his cited subsequent testimony. We note that, even with Patent Owner’s arguments, the record is clear that Patent Owner was on notice of Petitioner’s proposed definition of the level of ordinary skill at the time of the Petition. Pet. 7; cf. Corephotonics, Ltd. v. Apple Inc., 84 F.4th 990, 1006 (Fed. Cir. 2023) (holding that Petitioner is not required to anticipate all arguments in its Petition and allowing consideration of reply where patent owner had sufficient notice of petitioner’s position and adequate opportunity to respond).” slip op. at 14

      “explained below, we agree with Petitioner that Patent Owner’s additional requirement of evaluating the calibration data to determine the boundaries of the area represented by a grid point should not be included in the construction of either “grid point” or “non-uniform grid point.” Instead, based on the full record, we discern no reason to alter our prior construction of “grid point” as “a point associated with representative calibration data for an area” and maintain that construction for this Final Written Decision. The construction of “grid point” we adopt is supported by the Specification of the ’104 patent. Namely, the ’104 patent discloses that “[i]n general, a non-uniform grid point (NUG) may represent the signal characteristics and/or calibration data over a given region,” and “NUGs represent an area of collected calibration data.”18 Ex. 1001, 3:50–60. The district court identified the second quoted passage, which is identically recited in the ’104 patent (see Ex. 2018, 3:56–60) as “provid[ing] a clear indication of the meaning of ‘grid point.’” Ex. 2012, 19 (emphasis added). We agree with the district court’s analysis. Although the ’104 patent does not explain how a generic “grid point” might differ from the described “nonuniform grid point,” we do not find this distinction pertinent to construing “grid point” in this case because neither party raises this issue. Also, based on the claim wording “non-uniform grid point,” a “non-uniform grid point” is a type of grid point. See Pet. Reply 3 (explaining why that plain meaning supports Petitioner’s proposed construction). Furthermore, the district court construed “grid point” only, not “non-uniform grid point.” Ex. 2012, 18–20.” slip op. at 27
