Realtime Adaptive Streaming LLC v. Sling TV L.L.C. et al.

I'll research this case across multiple sources to build a verified overview.

Case Overview & Background

Parties and business models. The plaintiff, Realtime Adaptive Streaming LLC, is a patent-holding entity — not an operating company. EchoStar/DISH's SEC disclosures describe it as "an entity that seeks to license an acquired patent portfolio without itself practicing any of the claims recited therein," and Fish & Richardson's fee affidavit identifies Realtime Data LLC d/b/a IXO as Realtime Adaptive Streaming's parent (EchoStar 10-K disclosure; Shartzer affidavit, ECF 308-1). The patents trace to inventor James J. Fallon and a 2001 priority date; Realtime Data had earlier run a long E.D. Tex./S.D.N.Y. campaign over the same family against Packeteer, Morgan Stanley, Thomson Reuters, CME, T-Mobile, Microsoft, Oracle, SAP, Dell and others (see the exhibit lists in IPR2018-01331). Judge Jackson noted DISH's characterization of Realtime as a "serial litigant" with "some 145 cases" created by a patent attorney to license and monetize patents — while expressly saying that did not affect the merits (ECF 326 at 3). On the defense side are the DISH/EchoStar family and its streaming affiliate: Sling TV L.L.C. and Sling Media L.L.C. (both Colorado-based), DISH Network L.L.C., DISH Technologies L.L.C., and originally EchoStar Technologies L.L.C. and set-top-box vendor ARRIS Group, Inc. (ARRIS settled out and was dismissed March 10, 2021). DISH/Sling were represented by Fish & Richardson (Ruffin Cordell, Adam Shartzer) with Wheeler Trigg O'Donnell as Denver counsel; Realtime by Russ August & Kabat (Philip Wang, Reza Mirzaie, Brian Ledahl, Neil Rubin).

Accused technology and asserted patents. Realtime's infringement contentions targeted DISH's Hopper with Sling / Hopper 3 DVRs, the DISH Anywhere and Sling TV / Sling Fire App streaming apps, and ARRIS transcoder hardware (e.g., MS4000) — i.e., ordinary H.264 (MPEG-4 AVC) encoding and adaptive-bitrate transcoding. Its theory was that H.264's switchable entropy coders, CAVLC and CABAC, are the claimed "asymmetric compressors," selected based on profile/level parameters and channel conditions (infringement contentions reproduced at RPX Insight). Two patents, with virtually identical specifications, survived to be litigated: U.S. 8,934,535, "System and Methods for Video and Audio Data Storage and Distribution" — a method of determining a parameter/attribute of an audio-video data block, selecting an asymmetric compressor from among several based on that parameter (and an "access profile"), compressing, and storing the result; and U.S. 8,867,610, "System and Methods for Video and Audio Data Distribution" — claim 1 adds "a throughput of a communication channel" to the selection step, i.e., choosing among compression algorithms (at least one asymmetric) for transmission. A third patent, U.S. 8,275,897, was asserted in the original complaint and dropped in the October 2017 amended complaint. Claim 1 of the '610 and claim 15 (with claims 1 and 14) of the '535 were the operative claims.

Procedural posture, venue, and why it matters. The case is Realtime Adaptive Streaming LLC v. Sling TV L.L.C., No. 1:17-cv-02097-RBJ (D. Colo.), assigned to U.S. District Judge R. Brooke Jackson in Denver. It did not start there by accident: Realtime initially filed against Sling in E.D. Tex. and D. Colo. simultaneously; on August 31, 2017 — four months after TC Heartland — it dismissed the Sling defendants from the Texas action and refiled in Colorado, where Sling TV and DISH are headquartered in Englewood, then consolidated all defendants (DISH Network, DISH Technologies, ARRIS) into the Colorado case by second amended complaint on November 6, 2017 ([EchoStar 10-K narrative](https://ir.echostar.com

I'll research this case systematically across dockets, PTAB, and appellate records.

Good foundation. Now let me dig into the docket timeline, PTAB proceedings, and the post-remand events.

Now let me pin down the Markman details, stay order, discovery disputes, and the '535 IPRs.

Realtime Adaptive Streaming LLC v. Sling TV L.L.C. — Litigation Timeline & Outcome

Bottom line: The case is concluded in defendants' favor on every axis. The '535 patent claims were invalidated at the PTAB and dropped; the '610 patent's asserted claims were held ineligible under § 101 (affirmed) and were then separately cancelled in ex parte reexamination; DISH's $3.9M fee award was vacated on appeal and, on remand, denied. DISH's appeal of that denial was dismissed by agreement on 2025-07-03. No trial, no verdict, no damages.

1. Filing and initial pleadings

Two strategic footnotes worth preserving:

• The original plaintiff's identity became the central PTAB issue. Realtime Data had assigned the patents to Realtime Adaptive Streaming before filing, then voluntarily dismissed and re-filed. The PTAB later held that the earlier, standing-deficient complaint did not trigger § 315(b) — a ruling that ultimately destroyed the DISH IPR. Sling TV, L.L.C. v. Realtime Adaptive Streaming, LLC, IPR2018-01331, Paper 9 (P.T.A.B. Jan. 31, 2019).
• Forum consolidation: parallel E.D. Tex. suits (including No. 6:17-cv-00567 and No. 6:17-cv-00421) were dismissed without prejudice on 2017-11-08 in favor of the Colorado action. Realtime also asserted the '535 against Hulu and others in C.D. Cal., producing the adverse § 101 rulings that later drove the fee fight.

2. Pre-trial motions of substance

• 2018-03-07 — Motions to dismiss / judgment on the pleadings DENIED. Arris and DISH's Rule 12(b)(6) § 101 motion (ECF 47) and Sling's Rule 12(c) motion (ECF 48) were denied from the bench at the scheduling conference. Judge Jackson deferred to claim construction: he was "satisfied with the merits of Judge Schroeder's view, and that is we need to get these terms defined and then see where we are." (Tr. 2018-03-07, ECF 308-7.)
• 2018-03-09 — Consolidation (ECF 72). Realtime v. Polycom (1:17-cv-02692) and Realtime v. Apple

I'll start by verifying the four known articles and searching for additional coverage.

Let me verify the 2019 IPWatchdog roundup and search for additional coverage.

Press and analyst coverage of Realtime Adaptive Streaming v. Sling TV

The fee fight, not the infringement case, drove the coverage. The single most substantive piece of press on this litigation is Dennis Crouch's Patently‑O piece of 2024‑08‑25, "Red Flags Waved Off," which reported that the Federal Circuit (Judge Alan Albright sitting by designation) vacated and remanded Judge R. Brooke Jackson's § 285 exceptional-case ruling in No. 2023‑1035, 113 F.4th 1348 (Fed. Cir. Aug. 23, 2024). Crouch flagged the number that made the case quotable: DISH/Sling was awarded $3.9 million in fees "for seven months of pre-trial litigation" — on a request of roughly $5 million — in a case that ended at summary judgment on § 101. He characterized the opinion as "an important new opinion on attorney fees patent cases under § 285," i.e., a data point about how much deference district courts actually get under Octane Fitness. (The $3.9M figure and the Sept. 20, 2022 fee judgment are corroborated by EchoStar's own SEC disclosure, cited in the earlier section of this case file.)

Two law-firm analyses dug into which "red flags" survived. Akin's IP Newsflash blog (2024‑11‑05, syndicated via Lexology) and Timothy Bianchi's National Law Review article, "Federal Circuit Weighs in on Exceptional Case Determinations in Realtime Adaptive Streaming v. Sling TV and Dish," both walked the district court's six red flags item by item. As Akin summarized, only the C.D. Cal. Google and D. Del. Netflix § 101 rulings against related '535 claims were treated as legitimate red flags; the Federal Circuit rejected reliance on Adaptive Streaming v. Netflix, 836 F. App'x 900 (different technology), on the PTAB's '535 obviousness decisions and the '610 ex parte reexamination office actions (different statutory question and broader BRI claim construction, insufficiently explained by the district court), on DISH's two-paragraph Feb. 11, 2021 notice letter (Akin noted the court's warning that blessing such letters "would [lead] every party [to] send such letters early in litigation to ensure entitlement to attorneys' fees"), and on Dr. Bovik's expert report. Bianchi's account is useful as an independent chronology — complaint 2017‑08‑31 on three patents, stay pending IPR, '535 claims 1–14 invalid, '610 summary judgment 2021‑07‑31, § 101 affirmance 2023‑05‑11, fee vacatur 2024‑08‑23 — and it matches the docket record in the prior section of this file. Akin's practice tip was aimed at litigators: tie each fee ground to the issue you actually won on.

The earlier burst of coverage was procedural, and centered on § 315(b). When the PTAB instituted DISH/Sling's petitions on 2019‑01‑31 in IPR2018‑01331/'‑01342, it held that service of the 2017 Texas complaint by **Realtime Data LLC — which had already assigned the patents to Realtime Adaptive Streaming — did not trigger the

I'll research the counsel of record for Realtime Adaptive Streaming in this case using docket records, court opinions, and firm sources.

Good initial results. Let me pull the docket sheet and confirm appearances, plus local counsel details.

Let me verify docket appearances and current firm affiliations.

Counsel of Record for Plaintiff Realtime Adaptive Streaming LLC

Bottom line: Realtime was represented throughout by a Los Angeles plaintiff-side patent boutique, Russ August & Kabat ("RAK"), with a single Denver attorney, Eric B. Fenster, serving as Colorado/local counsel. No in-house counsel for Realtime appears of record — consistent with Realtime being a non-practicing licensing entity. No sealed or "appearance-pending" gaps exist here; the representation is visible across the 2017 complaint, the December 2018 Markman hearing, the July 2021 pretrial conference, the fee litigation, and three Federal Circuit appeals (21‑2268, 23‑1035, 25‑1529).

Table of attorneys

Key docket/citation support

• July 16, 2021 trial-preparation conference transcript (ECF No. 308‑12) lists plaintiff's appearances as "Reza Mirzaie, Philip X. Wang, Jay Chung, Adam S. Hoffman and James N. Pickens, Russ August & Kabat … Eric B. Fenster, Eric B. Fenster, LLC."
• Jan. 11, 2019 Markman Order (D. Colo.) — Realtime represented by Ledahl/Mirzaie/Fenster team.
• Fed. Cir. No. 21‑2268 judgment (May 11, 2023): "Brian David Ledahl … argued for plaintiff-appellant. Also represented by Marc A. Fenster, Reza Mirzaie, James S. Tsuei, Philip Wang, Shani M. Williams."
• Realtime's CAFC opening brief (Jan. 26, 2023, No. 23‑1035) signed by Philip X. Wang, with RAK counsel table.
• Fed. Cir. No. 25‑1529 ECF No. 6 (Apr. 2, 2025): entry of appearance for Realtime by Mirzaie, Ledahl, Kroeger, Wang, Williams.
• DISH's Feb. 11, 2021 Rule 11/§ 285 notice letter (ECF No. 308‑5) addressed to "Philip Wang, Russ August & Kabat" as Realtime's counsel.

Caveats

• I could not query PACER directly; the appearance data above is reconstructed from court transcripts and opinions, Federal Circuit filings, and PACER-derived aggregators (Justia, CourtListener/UniCourt, Docket Alarm mirrors). Individual ECF entry-of-appearance numbers for each RAK attorney in the 2017–2019 window were not all independently verified.
• "Formerly of Russ August & Kabat" designations for Chung, Tsuei, Hsieh and Hoffman come from the firm's own 2022–2023 appellate briefing captions; current affiliations beyond that were not confirmed.
• The record is not sealed as to plaintiff's counsel, and no in-house attorney for Realtime appears on the docket.
• Although the case's liability phase ended with cancellation of the '610 claims and the 2025 appeal was dismissed (Fed. Cir. No. 25‑1529, July 3, 2025), RAK's Mirzaie/Ledahl/Kroeger/Wang/Williams group remained Realtime's counsel of record through that dismissal.

I'll research defendant counsel from docket records, opinions, transcripts, and Federal Circuit filings.

Let me pull the docket sheet and the district court opinions to confirm appearances, including ARRIS and EchoStar counsel.

Let me get the full defense appearance list from the 2018 scheduling conference transcript and the district court's summary judgment opinion.

Counsel of Record for the Defendants

Bottom line: The DISH/Sling/EchoStar side was represented from start to finish by Fish & Richardson P.C., an IP-only firm, with Ruffin B. Cordell (Washington, DC) as lead counsel and Adam R. Shartzer (Washington, DC) as the principal trial/appellate advocate — Shartzer argued both Federal Circuit merits appeals. ARRIS was also represented by Fish & Richardson, but by a separate Atlanta-based team (Noah C. Graubart, Jonathan B. Bright). In April 2021, roughly three months before the summary-judgment ruling, the four DISH/Sling entities added Wheeler Trigg O'Donnell LLP of Denver as local/trial co-counsel (Hugh Q. Gottschalk), whose $103,986.50 in fees became a line item in the § 285 award. No in-house DISH/EchoStar lawyer appears of record, and EchoStar Technologies L.L.C. and Sling Media, Inc. never had separate counsel appear — they were nominal defendants who went unrepresented on appeal.

Fish & Richardson P.C. — counsel for DISH Network L.L.C., DISH Technologies L.L.C., Sling TV L.L.C., Sling Media L.L.C. (and initially EchoStar Technologies L.L.C.)

Fish & Richardson P.C. — separate team for ARRIS Group, Inc. / ARRIS Solutions, Inc.

Wheeler Trigg O'Donnell LLP — Denver co-counsel / local trial counsel (retained April 2021)

Coverage/gaps to flag

• EchoStar Technologies L.L.C. and Sling Media, Inc. were named defendants, and Cordell's Jan. 23, 2018 entry of appearance expressly covered EchoStar Technologies. But neither filed an appearance at the Federal Circuit — the clerk's Sept. 14, 2021 notice in No. 21-2268 warned them that no entry of appearance, certificate of interest, or docketing statement had been filed, and the court "revised [the] official caption to reflect the non-participation of EchoStar Technologies LLC and Sling Media, Inc." (No. 23-1035, Doc. 8, Nov. 9, 2022). Consistent with the caption in the 2025 dismissal order, they were parties below but not appellants. Also note the earlier "Key legal developments" section's statement that EchoStar was dismissed in the Texas action (Feb. 2019) — that is a different case; EchoStar Technologies remained a nominal Colorado defendant without separate counsel.
• No in-house counsel for any defendant appears on the docket or in any appellate filing I reviewed. The Fed. Cir. certificates of interest identify only Fish & Richardson and Wheeler Trigg O'Donnell as the firms that appeared below.
• Nothing is sealed as to defense counsel, and there are no "appearance-pending" gaps: the same Fish team (Cordell, Shartzer, Livedalen, Ballanco) entered appearances in the 2025 appeal (No. 25-1529, Doc. 2, Mar. 26, 2025) and remained counsel of record through the July 3, 2025 stipulated dismissal.
• Verification caveat: I could not query PACER directly. Firm, office, and role attributions above are drawn from the March 7, 2018 scheduling-conference transcript (ECF 308-7), the March 2, 2018 proposed scheduling order (ECF 70/75), the June 4, 2018 ARRIS substitution motion (ECF 103), the § 285 papers (ECF 308-3, 308-5), the Federal Circuit entries of appearance and Rule 47.4 statements, and the court's published opinions. Individual ECF entry-of-appearance numbers for each Fish attorney in the 2017–2019 window were not all independently confirmed; the Riffe/Tishman/Mosteller/Dean/Ellis/Park/Utreja/Teel/Schrader group is documented as "appeared below" only through DISH's own Rule 47.4 disclosure, not through docket entries I inspected.
