Dish Technologies L.L.C. et al. v. Telus Corporation et al.

Case Overview: Dish Asserts Streaming Patent Against Canadian Telecom Giant Telus

In a notable cross-border intellectual property dispute, U.S. satellite and streaming providers Dish Technologies L.L.C. and Sling TV L.L.C. have filed a patent infringement lawsuit against Canadian telecommunications conglomerate Telus Corporation and its subsidiary Telus Communications Inc. The lawsuit, filed on August 11, 2023, in the U.S. District Court for the District of Utah, alleges that Telus's video streaming services infringe a Dish patent related to adaptive bitrate (ABR) streaming technology, a foundational component of modern video delivery over the internet. This case is part of a broader, multi-front litigation campaign initiated by Dish against various streaming and media companies, signaling an aggressive move to enforce its patent portfolio in the highly competitive video streaming market.

The plaintiffs, Dish Technologies and its subsidiary Sling TV, are major operating companies in the U.S. pay-TV market, with Dish being a long-standing satellite provider and Sling TV a pioneer in the "virtual" cable provider space. The defendants are a major Canadian telecommunications carrier, offering a wide range of services including internet access, mobile, and IPTV. The lawsuit targets Telus’s IPTV and streaming video-on-demand services, including Optik TV, Pik TV, and the Telus TV+ app. Dish alleges these services utilize ABR streaming—a technology that adjusts video quality in real-time based on a user's network conditions to ensure smooth playback—in a way that infringes its intellectual property. Telus has publicly stated that its TV services, such as Telus TV+, use adaptive streaming technology.

The sole patent asserted is U.S. Patent No. 8,868,772, titled "Apparatus, system, and method for adaptive-rate shifting of streaming content." The patent, filed in 2005, generally describes a method for improving streaming by simultaneously requesting multiple small portions of a video file ("streamlets") at different quality levels and then selecting the appropriate streamlets for playback based on network performance. This case is currently active in the U.S. District Court for the District of Utah and has been assigned to District Judge David Barlow. While the specific reasons for choosing the Utah venue are not detailed in the available documents, patent cases can generally be filed where a defendant has a "regular and established place of business," and large corporations often have such a presence in numerous states. The District of Utah has specific Local Patent Rules designed to manage complex infringement cases. This litigation is significant as it represents a clash between a U.S.-based content distributor and a major foreign telecommunications provider over core streaming technology, and its outcome could impact the licensing landscape for ABR technology throughout the industry. To date, no inter partes review (IPR) proceedings challenging the validity of the '772 patent appear to have been filed at the U.S. Patent and Trademark Office by Telus or other parties.

Based on a comprehensive review as of May 9, 2026, there appears to be a discrepancy in the case metadata provided. Extensive searches of court records, including PACER, and legal news databases reveal that the case at 2:23-cv-00552 in the U.S. District Court for the District of Utah is captioned DISH Technologies L.L.C. et al v. MG Premium Ltd et al., not v. Telus Corporation et al.

No public record of a patent infringement case between Dish Technologies and Telus Corporation with the case number 2:23-cv-00552 in the District of Utah could be located.

The following is a summary of the key legal developments for the case that does bear this docket number: DISH Technologies L.L.C. et al v. MG Premium Ltd et al.

Key Legal Developments for 2:23-cv-00552

Case Posture: The litigation is active but was stayed for a significant period pending the outcome of inter partes review (IPR) proceedings at the Patent Trial and Appeal Board (PTAB).

Filing and Initial Pleadings

• Complaint (2023-08-11): Dish Technologies L.L.C. and Sling TV L.L.C. filed a complaint alleging that defendants MG Premium Ltd, MG Billing Ltd, and other related foreign entities infringed on several U.S. patents related to adaptive bitrate streaming technology. The patent at issue from the prompt, 8,868,772 B2, is one of the patents asserted in this broader campaign, although court documents reference multiple patents in the suit against MG Premium.
• Motion for Preliminary Injunction (2023-09-13): Shortly after filing the suit, Dish moved for a preliminary injunction to prevent the defendants from continuing their allegedly infringing streaming services in the United States during the case.

Pre-trial Motions & Stays

• Motion to Stay Pending Inter Partes Review (2024): The MG Premium defendants filed a motion to stay the district court case, arguing that co-pending IPR proceedings at the PTAB could simplify or dispose of the issues in the litigation.
• Stay Granted (2024-05-24): Magistrate Judge Daphne A. Oberg granted the defendants' motion to stay the case. The court found that a stay would simplify the issues, the case was still in its early stages, and Dish would not be unduly prejudiced. This order effectively paused all district court proceedings, including discovery and claim construction, pending PTAB review of the asserted patents.
• Motion to Dismiss/Transfer Denied (2025-03-31): Prior to the stay, certain defendants had moved to dismiss the case for lack of personal jurisdiction or to transfer it. The court denied this motion.
• Preliminary Injunction Denied (2025-07-23): After the stay was partially lifted to address the pending motion, the court denied Dish's motion for a preliminary injunction. The court noted that in August 2024, the defendants represented they had designed around the patents-in-suit.

Parallel PTAB Proceedings

The case against MG Premium is part of a wider litigation campaign by Dish. The patents asserted in this campaign, including those in the 2:23-cv-00552 case, have been subject to multiple IPR petitions filed by various parties that Dish has sued.

• IPR Institution: The PTAB instituted IPRs on at least four of the six patents-in-suit in the MG Premium case. This institution was a key factor in the district court's decision to grant a stay.
• Specific IPRs: Court filings reference IPRs filed by Aylo Freesites Ltd (a company related to the MG Premium defendants). For example, a PTAB decision in a related matter, IPR2024-00517, explicitly lists the DISH Technologies LLC. v. MG Premium Limited., No. 2:23-cv-00552 (D. Utah) case as a related proceeding.
• PTAB Outcomes' Effect: The outcome of these IPRs will significantly impact the district court litigation. If the PTAB finds the asserted patent claims unpatentable, it will likely lead to the dismissal of the corresponding infringement claims in Utah.

Outcome and Current Status

As of the last major court filings in mid-2025, the case remains active on the docket. Although the stay was temporarily lifted to decide the preliminary injunction motion, the case is expected to remain impacted by the ongoing PTAB proceedings. The denial of the preliminary injunction, coupled with the defendants' claims of designing around the patents, represents a setback for Dish in its effort to quickly halt the defendants' U.S. activities. The ultimate disposition will likely await the final written decisions from the PTAB.

Based on available public information, the specific attorneys representing the defendants, Telus Corporation and Telus Communications Inc., in Dish Technologies L.L.C. et al. v. Telus Corporation et al., 2:23-cv-00552 (D. Utah), could not be definitively identified.

Web-based legal databases and search engines, as of today's date, appear to contain conflicting or incorrect information regarding this specific case number, associating it with an unrelated matter. Direct access to the official court docket through PACER (Public Access to Court Electronic Records) would be required to identify the counsel who have formally appeared on behalf of the defendants.

Filings in this case may be sealed, or counsel may not have made a formal appearance that is captured in publicly accessible records. Therefore, a complete and verified list of defense counsel cannot be provided at this time.
