Foras Technologies v. Kia Corp.: Firmware Lockstep Patent Dispute Ends in Joint Dismissal
Foras Technologies, Ltd. asserted US7502958B2 — covering firmware recoverable lockstep protection — against Kia Corporation and Kia America, Inc. in the Eastern District of Texas. The parties jointly moved to dismiss without prejudice after 351 days, representing a resolution of Plaintiff’s claims, with each side bearing its own costs.
Firmware security patent asserted against Kia resolves quietly in E.D. Texas
Foras Technologies, Ltd. filed suit against Kia Corporation and its U.S. subsidiary Kia America, Inc. on May 18, 2023, in the Eastern District of Texas before Judge Rodney Gilstrap. The complaint alleged infringement of US7502958B2, a patent covering a system and method for providing firmware recoverable lockstep protection — a fault-tolerance mechanism relevant to embedded computing systems in modern vehicles.
The case closed on May 3, 2024, when Judge Gilstrap granted the parties’ joint motion to dismiss. The court order reflects that the parties represented they had ‘resolved Plaintiff’s claims for relief’ against Kia, resulting in a dismissal without prejudice. Each party was ordered to bear its own legal costs and expenses, and all pending relief not explicitly granted was denied as moot.
The 351-day duration and joint nature of the dismissal are consistent with a negotiated resolution reached before significant pre-trial milestones. The without-prejudice designation technically preserves Foras’s right to refile, though the parties’ own statement of resolution suggests this is unlikely. The precise financial terms, if any, remain undisclosed in the public record.

Dismissed without prejudice: what the joint motion means for both parties
Joint dismissal without prejudice — no merits adjudication
A dismissal without prejudice means the court made no ruling on the merits of the infringement claims. The case was terminated by agreement of both parties via a joint motion. Under this procedural posture, Foras Technologies retains the theoretical right to refile claims against Kia based on the same patent, subject to applicable statutes of limitations and any private settlement terms.
No merits rulingParties confirmed a resolution — but terms are sealed
The joint motion explicitly states the parties ‘have resolved Plaintiff’s claims for relief’ against Kia. This language goes beyond a bare procedural dismissal and suggests a settlement agreement exists. However, any financial terms, licensing arrangements, or covenants not to sue are not disclosed in the public docket. The without-prejudice label means Foras did not formally surrender future rights, though the stated resolution makes refiling less commercially probable.
Likely settled — terms undisclosedForas preserves flexibility; resolution achieved pre-trial
Foras Technologies achieved a case resolution without proceeding to claim construction, summary judgment, or trial — stages that carry significant legal and financial risk for patent asserters. The without-prejudice dismissal preserves optionality on paper. Whether Foras secured a licensing fee or other commercial consideration from Kia cannot be confirmed from public filings.
Pre-trial resolutionKia exits litigation without prejudgment on validity or infringement
Kia Corporation and Kia America, Inc. avoided a court ruling on patent infringement or validity of US7502958B2. No injunction or damages award appears on the public record. Each party bearing its own costs is a standard feature of negotiated dismissals and does not indicate fault. Kia’s firmware and embedded systems architecture remain unchallenged as a matter of judicial record.

Official order — verbatim text
The court’s order closely tracks the joint motion language, granting dismissal on the basis of the parties’ own representation that claims have been ‘resolved.’ The without-prejudice designation is notable: it preserves Foras’s nominal right to refile but does not affirmatively indicate a covenant not to sue. The denial of all remaining relief as moot confirms no subsidiary claims or motions survived the dismissal. No validity or infringement findings were made.
US7502958B2 — Firmware Recoverable Lockstep Protection System
US7502958B2, filed under application number US10/973076, covers a system and method for providing firmware recoverable lockstep protection. Lockstep processing involves running redundant processor cores executing identical instructions simultaneously to detect faults — a foundational technique in safety-critical embedded systems. The patent’s firmware recovery dimension addresses how systems restore correct operation after detected fault divergence, a gap in earlier hardware-only lockstep implementations.
This patent sits at the intersection of functional safety and embedded firmware engineering — an increasingly contested space as automotive OEMs adopt ISO 26262-compliant microcontrollers across powertrain, chassis, and ADAS applications. Dual-core lockstep processors from suppliers such as Texas Instruments and Infineon are pervasive in modern vehicle ECUs. Any company developing or integrating firmware for safety-critical automotive controllers should evaluate whether their implementation overlaps with the claims of this patent and related continuations.
Should your team run an FTO against US7502958B2?
Automotive OEMs, Tier 1 ECU suppliers, and embedded software vendors developing firmware for lockstep-capable microcontrollers should consider a freedom-to-operate assessment against US7502958B2. The Kia dismissal without prejudice and the absence of a public license mean this patent remains formally enforceable. Companies deploying firmware recovery routines in dual-core lockstep architectures — particularly in ISO 26262-relevant applications — face the most direct exposure.

Foras v Kia — key questions answered
The case was dismissed without prejudice on May 3, 2024, pursuant to a joint motion filed by both parties. The parties represented that they had resolved Plaintiff’s claims. Each side was ordered to bear its own attorneys’ fees and costs. No merits ruling on infringement or patent validity was issued.
Foras Technologies asserted US7502958B2, titled ‘System and Method for Providing Firmware Recoverable Lockstep Protection,’ filed under application number US10/973076. The patent covers fault-tolerant embedded computing techniques relevant to safety-critical automotive electronic control units.
Technically yes — a without-prejudice dismissal does not bar Foras from refiling claims based on the same patent against Kia, subject to any applicable statute of limitations and any private settlement terms not visible in the public record. However, the joint motion’s language stating claims have been ‘resolved’ suggests refiling is unlikely in practice.
Foras Technologies was represented by Brett E. Cooper, Drew Bennett Hollander, Jonathan Randy Yim, Justin Kurt Truelove, and Seth Raymond Hasenour of BC Law Group PC and Truelove Law Firm. Kia was represented by Andrew Thompson Gorham of Gillam & Smith, LLP. The case was presided over by Judge Rodney Gilstrap.
