DH International v. Apple: NFC Patent Dispute Dismissed Pending PTAB Review

In a strategically calculated move, DH International, Ltd. dismissed its patent infringement lawsuit against Apple Inc. without prejudice on January 8, 2025, just 131 days after filing in the Northern District of California. The case—centered on U.S. Patent Nos. 7,628,333 and 9,022,294 covering NFC and mobile payment technologies—targeted some of Apple’s most commercially significant products, including iPhone 14 Pro, Apple Watch Series 8, Apple Watch Ultra, and Apple Pay-enabled devices.

Rather than proceed to costly litigation, both parties agreed to pause the dispute pending resolution of four Inter Partes Review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB). Critically, the dismissal preserved DH International’s damages window by tolling the six-year statutory damages period under 35 U.S.C. § 286, protecting its ability to recover royalties dating back to September 15, 2017.

For patent attorneys, IP professionals, and R&D teams operating in the NFC and mobile payments space, this case offers a textbook example of coordinated PTAB-district court litigation strategy—and the leverage that IPR proceedings can generate at the negotiating table.

Case Overview

The Parties

The Patents at Issue

This case involved two foundational patents covering NFC and mobile payment technologies:

• • U.S. Patent No. 7,628,333 — Covers NFC-based data transfer and transaction processing technology.
• • U.S. Patent No. 9,022,294 — Addresses mobile device transaction and NFC communication architecture.

Litigation Timeline & Procedural History

The complaint was filed on August 30, 2024, in the **Northern District of California**—a deliberate venue choice given Apple’s headquarters in Cupertino and the court’s deep familiarity with complex technology patent disputes.

The case moved swiftly. At the December 5, 2024 Initial Case Management Conference before **Chief Judge Trina L. Thompson**, both parties raised the possibility of staying proceedings pending PTAB resolution. Judge Thompson’s feedback regarding compliance with the Federal Judiciary Act directed the parties to seek dismissal rather than an indefinite stay—a procedural signal that accelerated resolution.

The case closed in just **131 days**, well below average district court patent litigation timelines. Four parallel IPR petitions (IPR2025-00172 and IPR2025-00173 confirmed in the record) were already in motion before PTAB, signaling that Apple’s defense team had rapidly mobilized a multi-front invalidity challenge.

The Verdict & Legal Analysis

Outcome

The case was **dismissed without prejudice** via joint stipulation (Dkt. No. 89-90, filed January 8, 2025), with each party bearing its own costs and attorneys’ fees. No damages were awarded, and no injunctive relief was granted or denied on the merits. Critically, the dismissal contains no admission of liability or concession on any claim or defense.

The § 286 Tolling Agreement: The Critical Clause

The most strategically significant element of this dismissal is the **tolling of 35 U.S.C. § 286**. Under standard patent law, plaintiffs can only recover damages for infringement occurring within six years prior to filing suit. By anchoring the tolling date to the **September 15, 2023 filing date** (the original lawsuit filing referenced in the stipulation), DH International locked in the ability to pursue damages for infringement dating back to **September 15, 2017**—spanning the bulk of Apple Pay’s commercial growth period.

If Apple argues § 286 in any subsequent refiling, the parties have agreed to resolve the damages dispute in **private arbitration**, using evidence and expert reports from the subsequent litigation. This arbitration carve-out is an unusual and sophisticated provision that effectively immunizes DH International’s damages claim from a statute of limitations defense.

PTAB Strategy as Litigation Leverage

Apple’s rapid filing of IPR petitions against both asserted patents reflects a well-established big-tech defense playbook: challenge patent validity at PTAB while simultaneously forcing district court proceedings to pause. With a PTAB institution decision carrying potential estoppel consequences and the possibility of claim cancellation, DH International faced significant incentive to accept a structured dismissal rather than risk litigating under a cloud of invalidity.

The four IPR proceedings—two confirmed (IPR2025-00172 and IPR2025-00173)—will now serve as the critical battleground. Should PTAB confirm the patents’ validity, DH International retains a fully preserved damages window and a contractually agreed venue (N.D. Cal.) for refiling.

Legal Significance

This case illustrates the **PTAB-first defense strategy** that large technology defendants routinely deploy against NPE (non-practicing entity) assertions. The Northern District of California’s receptiveness to this approach—evidenced by Judge Thompson’s direction to dismiss rather than stay—reflects broader judicial efficiency concerns with indefinite litigation holds.

The tolling provision also highlights an emerging negotiating dynamic: patent plaintiffs are increasingly demanding § 286 protections as the price of agreeing to IPR-driven dismissals, recognizing that multi-year PTAB proceedings can otherwise erode recoverable damages periods.

Industry & Competitive Implications

The NFC mobile payments patent landscape remains intensely active. Apple Pay’s dominance—combined with the proliferation of NFC-enabled wearables—makes Apple a recurring litigation target for NFC patent portfolios. This case follows a broader pattern of NPEs asserting foundational mobile payment patents against platform companies as licensing leverage.

The outcome reflects a **market reality**: when a patent holder faces a well-resourced defendant capable of mounting simultaneous PTAB and district court challenges, structured dismissals with preserved damages windows may represent optimal value capture—particularly where patent validity remains uncertain pending IPR resolution.

For companies in the NFC, fintech, and mobile device space, this litigation signals that patents covering transaction processing architecture from the mid-2000s remain commercially viable assertion vehicles, provided the holder can survive PTAB scrutiny. Licensing strategies in this space should anticipate IPR exposure as a near-certainty against major technology defendants.
