APPLE, INC. v. Touchmusic Entertainment LLC

This case, IPR2025-00700, involves an inter partes review (IPR) proceeding initiated by technology giant Apple, Inc. against Touchmusic Entertainment LLC at the Patent Trial and Appeal Board (PTAB). Apple, Inc. is a well-known operating company that designs, manufactures, and markets consumer electronics, software, and online services. Touchmusic Entertainment LLC appears to operate as a Patent Assertion Entity (PAE) or Non-Practicing Entity (NPE), as evidenced by its engagement in patent litigation against Apple and the assignment of the patent at issue to Ziklag IP LLC for IPR proceedings.

The sole patent challenged in this IPR is US Patent 6,182,128, titled "Internet based global content distribution system and method." This patent broadly covers systems and methods for distributing content globally over the internet. While the specific accused product or service from Apple triggering this IPR is not explicitly detailed in publicly available summaries of the IPR petition or institution decision, given the patent's scope, it likely relates to Apple's extensive content distribution platforms, such as iTunes, Apple Music, or the App Store.

The procedural posture places this case before the Patent Trial and Appeal Board (PTAB), a specialized administrative court within the United States Patent and Trademark Office (USPTO). The PTAB has already instituted this inter partes review, meaning it has determined that there is a reasonable likelihood that Apple would prevail in demonstrating the unpatentability of at least one challenged claim of US Patent 6,182,128. The PTAB serves as a critical venue for challenging patent validity on prior art grounds (35 U.S.C. §§ 102 or 103), often offering a more expedited and cost-effective alternative to district court litigation for accused infringers like Apple.

This case is notable as it exemplifies Apple's aggressive and consistent strategy of utilizing IPRs to challenge patents asserted against its products and services, particularly those held by NPEs. The institution of this IPR is also noteworthy given recent changes at the PTAB, where the USPTO Director now personally reviews all institution determinations and has sometimes issued discretionary denials. The fact that this IPR was instituted suggests that Apple presented a sufficiently strong challenge to the validity of the "Internet based global content distribution system and method" patent.

This case is currently pending, with an Inter Partes Review (IPR) instituted by the PTAB. There is also a parallel district court litigation that has experienced significant activity, including a motion to dismiss and an appeal to the Federal Circuit.

Here's a chronological overview of the key legal developments and outcomes:

*District Court Litigation: Ziklag IP LLC v. Apple Inc. (originally Touchmusic Entertainment LLC v. Apple Inc.)*

• 2024-03-02: Initial Complaint Filed. Touchmusic Entertainment LLC filed an initial complaint against Apple Inc. in the United States District Court for the Northern District of Illinois, alleging infringement of US Patent No. 6,182,128. The '128 patent expired on March 5, 2018. The complaint sought damages for infringement from March 2, 2018, to March 5, 2018.
• 2024-05-24: Amended Complaint Filed; Plaintiff Substituted. Ziklag IP LLC, formed in Tennessee on April 18, 2024, filed an amended complaint, substituting itself as the plaintiff. Ziklag alleged that Touchmusic assigned the '128 patent to it on April 18, 2024. The amended complaint asserted the same claims for infringement of the '128 patent as the initial complaint.
• 2024-05-31: Joint Motion to Stay Discovery Deadlines. Apple and Ziklag filed a joint motion to stay discovery deadlines, including those under the Northern District of Illinois Local Patent Rules, pending the disposition of Apple's forthcoming motion to dismiss.
• Forthcoming Motion to Dismiss by Apple. Apple intended to file a motion to dismiss Ziklag's claims as time-barred, arguing that Touchmusic lacked the power to file suit due to its suspended corporate status in California from August 1, 2014, to April 12, 2024. Apple further asserted that Touchmusic's revival of its corporate status and the subsequent assignment of the patent to Ziklag after the statute of limitations expired did not defeat Apple's statute of limitations defense. Both parties agreed that resolving this threshold issue before discovery or claim construction would be efficient.
• 2025-05-02: Appeal to Federal Circuit. Touchmusic Entertainment LLC filed an appeal to the U.S. Court of Appeals for the Federal Circuit, case number 25-1733. This indicates that a substantive decision, likely the motion to dismiss, was issued by the district court before this date, and Touchmusic (or Ziklag, as its successor in interest) appealed.
• 2025-10-09: Federal Circuit Order Granting Extension. The Federal Circuit issued a "TEXT ONLY" order granting a motion to extend time to file the appendix for Appellant Ziklag IP LLC, setting a new deadline of October 15, 2025.

Parallel PTAB IPR Proceedings: IPR2025-00700 (Apple Inc. v. Touchmusic Entertainment LLC / Ziklag IP LLC)

• 2025-05-13: IPR Petition Filed. Apple Inc. filed IPR2025-00700 challenging US Patent 6,182,128.
• 2025-10-31: Ziklag IP LLC Appoints Counsel for IPR. Ziklag IP LLC, identified as the owner of U.S. Patent No. 6,182,128 by assignment from Touchmusic Entertainment LLC, appointed practitioners as its attorneys to transact business in the USPTO associated with the inter partes review. This confirms Ziklag IP LLC as the Patent Owner in the IPR proceeding.
• Status: Instituted. The PTAB has instituted this inter partes review.

Other Related PTAB Proceedings:

• 2025-10-10: Amazon Web Services Inc. Files IPR. Amazon Web Services Inc. also filed an IPR against Touchmusic Entertainment LLC / Ziklag IP LLC for US Patent 6,182,128 (IPR2026-00047). This IPR was instituted on April 6, 2026, and is currently pending. This indicates a broader challenge to the '128 patent by major tech companies.
