PTAB challenges

Proceedings overview

U.S. Patent 11,677,798 B2 has been the subject of four AIA trial proceedings at the Patent Trial and Appeal Board (PTAB). Two of these proceedings (IPR2024-00043 and IPR2024-00901) resulted in Final Written Decisions, but the specific claim-level outcomes (which claims were invalidated or sustained) are not publicly detailed in the readily available search results. The other two proceedings (IPR2024-00517 and IPR2025-00470) were denied institution on procedural grounds. Given the lack of specific invalidation details for the concluded IPRs, the defensive posture for a defendant is complex; the patent has faced challenges, but the extent to which its claims have been narrowed is unclear from public summaries.

IPR2024-00901 — fuboTV Media Inc. / Aylo Freesites Ltd. v. DISH Technologies L.L.C.

• Type: Inter Partes Review
• Filed: 2024-05-13
• Status: Final Written Decision was issued on 2025-04-29.
• Judge panel: Not publicly available in the search results.
• Petition grounds: Details regarding the specific claims challenged, prior art asserted, and statutory basis (§ 102 / § 103) are not publicly detailed in the search results.
• Institution decision: Instituted on 2024-08-13. The reasoning for institution is not publicly detailed in the search results.
• Final Written Decision (if issued): A Final Written Decision was issued on 2025-04-29. However, the specific claims invalidated or held patentable, and the panel's reasoning, are not publicly detailed in the search results.
• Settlement / termination: Not indicated as settled or terminated prior to FWD.
• Appeal: No specific appeal to the Federal Circuit for this IPR (IPR2024-00901) against US11677798B2 was found in the search results. General CAFC case numbers listed in the patent's metadata do not explicitly link to this specific IPR.
• Defensive value: This proceeding resulted in a Final Written Decision, indicating a full review of the challenged claims. However, without knowing the specific claims that were invalidated or sustained, it is difficult to assess the direct impact. Defendants should investigate the full FWD to understand which claims, if any, remain enforceable.

IPR2024-00043 — Google LLC v. DISH Technologies L.L.C.

• Type: Inter Partes Review
• Filed: The filing date is not explicitly available in the current search results, but it was confirmed to challenge U.S. Patent 11,677,798 [cite: 41 (previous search)].
• Status: A Final Written Decision was issued.
• Judge panel: Not publicly available in the search results.
• Petition grounds: Details regarding the specific claims challenged, prior art asserted, and statutory basis (§ 102 / § 103) are not publicly detailed in the search results.
• Institution decision: The institution date is not explicitly available in the current search results, nor is the reasoning for institution.
• Final Written Decision (if issued): A Final Written Decision was issued for this IPR. However, the specific claims invalidated or held patentable, and the panel's reasoning, are not publicly detailed in the search results.
• Settlement / termination: Not indicated as settled or terminated prior to FWD.
• Appeal: No specific appeal to the Federal Circuit for this IPR (IPR2024-00043) against US11677798B2 was found in the search results.
• Defensive value: This IPR concluded with a Final Written Decision. However, without access to the full decision detailing the claims' validity, its direct defensive value is undetermined. Further investigation of the FWD is necessary to understand which, if any, claims survived or were canceled.

IPR2025-00470 — WEBGROUP CZECH REPUBLIC, A.S. v. DISH Technologies L.L.C.

• Type: Inter Partes Review
• Filed: 2025-01-17 [cite: 15 (previous search)]
• Status: Not Instituted - Procedural. The institution was denied on 2025-05-16. [cite: 15 (previous search)]
• Judge panel: Not publicly available in the search results.
• Petition grounds: Challenged claims 1-25 of U.S. Patent 11,677,798B2. The grounds were asserted as obviousness/anticipation based on prior art that was "substantially the same" as previously presented to the Office. [cite: 15 (previous search)]
• Institution decision: Denied institution on 2025-05-16. [cite: 15 (previous search)] The Board exercised its discretion under 35 U.S.C. § 325(d) due to the petitioner's "failure to identify any material error in the Office's prior evaluations, coupled with its reliance on substantially the same art." The petition was deemed "redundant, untimely, and unsupported," implying "litigation gamesmanship." [cite: 15 (previous search)]
• Final Written Decision: Not applicable as institution was denied.
• Settlement / termination: Not applicable as institution was denied.
• Appeal: Not applicable as institution was denied and such decisions are generally non-appealable.
• Defensive value: The procedural denial under § 325(d) means that claims 1-25 were not substantively reviewed for patentability by the PTAB in this proceeding. This outcome does not invalidate any claims but indicates that the petitioner's grounds were considered a rehash of prior arguments, potentially hardening these claims against future challenges using the same prior art. For a new defendant, this indicates that presenting substantially similar prior art or arguments may face a similar discretionary denial.

IPR2024-00517 — (Petitioner Not Publicly Listed) v. DISH Technologies L.L.C.

• Type: Inter Partes Review
• Filed: The filing date is not explicitly available in the search results.
• Status: Not Instituted - Procedural.
• Judge panel: Not publicly available in the search results.
• Petition grounds: Details regarding the specific claims challenged, prior art asserted, and statutory basis are not publicly detailed. It was confirmed to challenge U.S. Patent 11,677,798 [cite: 41 (previous search)].
• Institution decision: Denied institution on procedural grounds. The specific date and detailed reasoning for the procedural denial are not publicly available in the search results.
• Final Written Decision: Not applicable as institution was denied.
• Settlement / termination: Not applicable as institution was denied.
• Appeal: Not applicable as institution was denied.
• Defensive value: Similar to IPR2025-00470, this procedural denial does not invalidate any claims. Without the specific reason for denial, it's harder to gauge the precise defensive implications, but it signals that the petition did not meet the procedural thresholds for IPR initiation.

Strategic summary

Two IPRs, IPR2024-00043 and IPR2024-00901, proceeded to Final Written Decisions. However, the available public search results do not explicitly detail which specific claims of US11677798B2 were invalidated or sustained in these decisions. Without this crucial claim-level granularity, it is impossible to definitively state which claims are CANCELED vs. SUSTAINED vs. UNTESTED. The remaining claims are therefore presumptively still valid for assertion, pending review of the full FWDs.

Regarding the estoppel landscape, for IPR2025-00470, the institution was denied under 35 U.S.C. § 325(d) because the petition presented "substantially the same prior art or arguments previously were presented to the Office" [cite: 15 (previous search)]. This means that WEBGROUP CZECH REPUBLIC, A.S. (and its privies) would likely be estopped from challenging claims 1-25 of the '798 patent in district court or other PTAB proceedings using the grounds that were raised or reasonably could have been raised in that IPR petition. For a defendant currently being asserted against, this specific prior art and line of argument might be unavailable if they are in privity with Webgroup Czech Republic. For the other "Not Instituted - Procedural" case (IPR2024-00517), without the specific denial reason and petitioner, the estoppel implications are less clear. For the two IPRs that went to FWD, a petitioner (and its privies) is estopped from asserting in future proceedings any invalidity ground that was raised or reasonably could have been raised during those IPRs (35 U.S.C. § 315(e)(2)). This means that any prior-art grounds actually adjudicated in the FWDs, and any that could have been asserted with reasonable diligence, are unavailable to the petitioners (Google LLC, fuboTV Media Inc., Aylo Freesites Ltd.) and their privies in subsequent litigation.

A pattern signal is that DISH Technologies L.L.C. is actively defending its patents, as evidenced by the procedural denials of some IPRs and the completion of FWDs in others. The multiple IPR filings by different petitioners (Google, fuboTV, Aylo Freesites, Webgroup Czech Republic) indicate that the patent family is a significant target for validity challenges, likely due to its assertion in numerous district court litigations by DISH.

Recommended next steps

• For defendants currently facing assertion of U.S. Patent 11,677,798 B2 by DISH Technologies L.L.C., the absolute priority is to obtain and thoroughly review the full Final Written Decisions for IPR2024-00043 and IPR2024-00901. These documents will contain the precise claim-by-claim outcomes, the prior art considered, and the PTAB's reasoning. This information is critical for understanding the scope of the surviving claims and informing any potential invalidity defenses.
• Given the challenges in obtaining detailed outcomes from public summaries, consider direct access to the USPTO's Patent Trial and Appeal Board End-to-End (PTAB E2E) system or engaging a firm with such access to retrieve the specific orders for these proceedings.
• For IPR2025-00470, the denial under § 325(d) for presenting "substantially the same art" means that any new challenge should carefully curate its prior art and arguments to avoid a similar discretionary denial, focusing on genuinely new grounds or demonstrating a material error in the Office's prior evaluations.
• Since the patent is undergoing active litigation (as noted in the previously generated sections), any ongoing or new PTAB filings should consider the implications of potential parallel litigation denials (Fintiv factors) and estoppel effects.
• No active proceedings are currently pending beyond the FWDs issued in IPR2024-00043 and IPR2024-00901, and the denials of institution for IPR2024-00517 and IPR2025-00470. Therefore, no immediate trial-stage milestones are relevant for these specific proceedings against US11677798B2.
