Samsung Electronics Co., Ltd. v. CM HK Limited

[Samsung Electronics Co., Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) (Samsung), a global technology leader known for its vast portfolio of consumer electronics, mobile devices, and semiconductors, is the petitioner in this Inter Partes Review (IPR) proceeding. The respondent and patent owner, CM HK Limited, appears to be an entity asserting U.S. Patent No. 10,852,846 against Samsung. While there is a well-known operating company, China Mobile Hong Kong Company Limited ("CMHK"), which is a mobile network operator and a subsidiary of China Mobile Limited, the available information suggests that CM HK Limited in this patent litigation context may be a different entity or a vehicle for patent assertion, as it has filed a patent infringement lawsuit against Samsung in the Eastern District of Texas (Case No. 2:24-cv-00880). The specific product, service, or technology accused of infringement by CM HK Limited is not detailed in the provided search results but is the underlying basis for Samsung's challenge to the patent's validity.

The patent at issue, U.S. Patent No. 10,852,846, is currently under review for its validity by the Patent Trial and Appeal Board (PTAB) of the USPTO. While a detailed technical sketch of this specific patent is not explicitly provided in the search results, related IPR proceedings involving Samsung as a petitioner have challenged patents in the realm of wireless communication technologies, such as enhanced distributed channel access, device coexistence, and multi-user uplink transmission. The procedural posture of this case is an IPR, IPR2025-01023, which has been instituted by the PTAB, meaning the Board has determined there is a reasonable likelihood that Samsung would prevail on at least one challenged claim. The PTAB is a specialized administrative court within the USPTO that handles challenges to patent validity, often operating as a quicker and less expensive alternative to district court litigation. The Director of the USPTO has recently centralized authority over institution decisions, including discretionary denials, which now weigh heavily on factors like parallel district court proceedings and the timing of trial dates.

This case is notable due to its IPR linkage with potential parallel district court litigation initiated by CM HK Limited against Samsung. Samsung frequently utilizes IPRs as a key part of its patent strategy, proactively challenging the validity of competitor and Non-Practicing Entity (NPE) patents. The interplay between the PTAB's IPR process and any co-pending district court infringement suit highlights the ongoing strategic considerations for both patent owners and challengers in managing patent disputes. The outcome of this IPR could significantly impact the broader patent litigation landscape between these parties, potentially invalidating CM HK Limited's patent and influencing any associated infringement claims.

This case involves both district court litigation and a parallel IPR proceeding.

District Court Litigation (CM HK Limited v. Samsung Electronics Co., Ltd., E.D. Tex. Case No. 2:24-cv-00880)

• Filing & Initial Pleadings:

  • 2024-10-31: CM HK Limited filed a complaint for patent infringement against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the U.S. District Court for the Eastern District of Texas, accusing Samsung of infringing U.S. Patent Nos. 10,852,846 and 11,698,687.
  • 2025-01-28: CM HK filed an amended complaint for patent infringement.
  • 2025-01-28: CM HK served its infringement contentions.
  • 2025-03-04: Samsung served its invalidity contentions.

• Pre-trial motions of substance:

  • 2025-01-28: CM HK filed a motion to dismiss for lack of personal jurisdiction.
  • 2025-05-15: The Court granted CM HK's motion to dismiss, finding Samsung failed to establish that CM HK is subject to the court's specific jurisdiction. However, the Court allowed Samsung to seek jurisdictional discovery.
  • 2025-06-10: At the parties' request, the court vacated all deadlines from the Scheduling Order, pending jurisdictional discovery.
  • 2025-08-13: CM HK filed a Rule 11 motion for sanctions against Samsung in a related case in the Northern District of California (4:24-cv-06567), alleging procedural gamesmanship, legally deficient alter ego allegations, and strategic intent to delay adjudication.
  • The court denied CM HK's motion for sanctions, finding Samsung's alter ego theory credible enough to warrant jurisdictional discovery.

• Claim Construction (Markman) outcomes:

  • 2025-03-28: The parties exchanged proposed terms for construction under Patent L.R. 4-1.
  • 2025-05-13: The parties filed their Joint Claim Construction and Prehearing Statement.
  • A claim construction hearing has not yet been set as of the denial of CM HK's motion for sanctions.

• Discovery milestones:

  • 2025-08-12: Samsung vigorously pursued jurisdictional discovery, including filing a motion to compel.
  • In a related Northern District of California case (4:24-cv-06567), the court partially granted and partially denied CM HK's discovery letter regarding interrogatories and a 30(b)(6) deposition notice served on Samsung. The court denied CM HK's request to compel Samsung to identify corporate witnesses and provide deposition dates but granted CM HK's request to have Samsung verify interrogatory responses already provided.

• Final disposition or present posture:

  • 2025-08-20: The Texas litigation was stayed pending the outcome of a related California litigation.

Parallel PTAB IPR Proceedings (IPR2025-01023)

• Filing and Institution:

  • Samsung filed IPR2025-01023 challenging U.S. Patent No. 10,852,846 in June 2025.
  • The PTAB instituted a trial in this IPR proceeding. The precise institution date is not readily available in the provided snippets, but the case is currently listed as "Pending - Instituted."
  • 2026-04-06: The Patent Owner, CM HK Limited, filed its response to the petition.

• Effect of PTAB proceedings on district court litigation:

  • The district court litigation in the Eastern District of Texas was stayed pending the outcome of a related California litigation, which itself involved jurisdictional discovery and motions for sanctions related to the patents at issue, including 10,852,846.
  • The institution of the IPR by the PTAB could lead to a further stay of the district court litigation if it wasn't already stayed, or impact any existing stay.
  • 2025-10-17: USPTO Director John Squires reclaimed personal authority over all IPR and PGR institution decisions, effective October 20, 2025. This change emphasizes centralized control over institution decisions, with routine decisions issued as summary notices and detailed reasoning reserved for novel or important issues. This shift in policy might affect how future IPRs are handled or reviewed, but IPR2025-01023 was already instituted.

Outside Counsel:

The specific outside counsel firm representing Samsung in this particular IPR (IPR2025-01023) is not explicitly named in the provided PTAB document snippet, which only lists "Modi, Naveenet al" as counsel for Samsung Electronics Co., Ltd.. However, in a related patent infringement case in the Eastern District of Texas (CM HK Limited v. Samsung Electronics Co LTD et al, Case No. 2:24-cv-00880), Samsung is represented by:

• Elizabeth Louise Brann
  • Role: Counsel
  • Firm: Paul Hastings, LLP

It is common for Samsung to work with prominent IP litigation firms like Paul Hastings, LLP, for its patent disputes. While these specific attorneys are listed for the district court case, it's highly probable that attorneys from Paul Hastings or another major IP firm are also actively involved in the related IPR proceeding, working in conjunction with Samsung's in-house team. Without direct PTAB docket entries detailing outside counsel for IPR2025-01023 beyond the "Counsel Name" field, a definitive list of outside counsel for this specific IPR cannot be provided at this time.

The user is asking for the counsel of record representing CM HK Limited in the IPR2025-01023 proceeding and the related district court case. I need to find the names, roles, firms, office locations, and relevant experience for these attorneys.

I will start by looking for counsel in the IPR proceeding, then for the district court case.

My previous search for Samsung's counsel in the IPR only returned "Modi, Naveen et al" without a specific firm, so it's possible the PTAB record doesn't always explicitly list the firm in public snippets or the full record needs to be accessed. I will try to find a more detailed docket or document for IPR2025-01023.

For the district court case, I have the case number (2:24-cv-00880 E.D. Tex.). I will search for the docket to identify CM HK Limited's counsel.## Defendant Representatives
