Robinson v. Global Semiconductor Alliance: FOCL Patent Claim Dismissed in 64 Days
Kay C Robinson Jr brought an infringement action against the Global Semiconductor Alliance in Michigan’s Eastern District, asserting US11108397B2 covering fiber-optic connected logic (FOCL) technology. The court dismissed Robinson’s cause of action without prejudice in just 64 days — leaving the door open for future re-filing.
FOCL infringement claim ends early — but the dispute may not be over
On July 10, 2024, Kay C Robinson Jr filed an infringement action against the Global Semiconductor Alliance (GSA) in the United States District Court for the Eastern District of Michigan, asserting US11108397B2. The patent covers fiber-optic connected logic (FOCL), a technology relevant to high-speed semiconductor interconnect architectures. Robinson appeared to act pro se, with no plaintiff law firm recorded in the public docket.
The case was resolved on September 12, 2024, when Judge Jonathan J.C. Grey ordered Robinson’s cause of action dismissed without prejudice. A dismissal without prejudice means the claim has not been adjudicated on its merits: Robinson is legally permitted to re-file the same infringement action at a future date, subject to applicable statutes of limitations and procedural requirements.
The 64-day resolution is notably short, suggesting the dismissal was likely procedural rather than the product of substantive litigation. The public record does not specify whether the dismissal arose from a motion to dismiss, a court-initiated order, or a voluntary action by Robinson. The absence of defendant counsel on record and the brevity of the proceedings are consistent with early-stage procedural hurdles common in pro se patent filings.

Dismissed without prejudice: what the ruling means for both parties
Dismissal without prejudice leaves the merits untouched
A dismissal without prejudice is a procedural termination — the court has not ruled on whether US11108397B2 is infringed, valid, or enforceable. No judgment on the merits has been entered. This is distinct from a dismissal with prejudice, which would bar Robinson from re-filing the same claim. The legal dispute over the FOCL patent remains formally unresolved.
No merits adjudicationRobinson retains the right to re-file — under the right conditions
Because the dismissal is without prejudice, Robinson can potentially bring a new infringement action on US11108397B2 against GSA or other parties. However, re-filing would require satisfying pleading standards under Iqbal/Twombly, complying with local patent rules, and acting within applicable limitations periods. The brevity of this case suggests Robinson may need to strengthen the complaint before any future filing.
Re-filing remains possibleGSA escapes judgment — but cloud on the patent persists
The Global Semiconductor Alliance obtains a clean exit from this proceeding without any finding of infringement or validity. No injunction, damages, or adverse ruling was entered. However, because the dismissal is without prejudice, GSA and its member companies cannot treat the US11108397B2 dispute as permanently closed. The FOCL patent remains in force and could support a future, better-pleaded action.
Dispute not permanently resolvedSemiconductor interconnect IP: unresolved risk for FOCL adopters
US11108397B2 covering FOCL technology has not been invalidated or held unenforceable. Companies in the semiconductor interconnect and photonic integration space that rely on fiber-optic connected logic architectures should note that the patent survived this proceeding without challenge on the merits. The lack of a substantive ruling means the patent’s scope and enforceability remain untested in court.

Official order — verbatim text
The court’s order that Robinson’s cause of action is ‘DISMISSED WITHOUT PREJUDICE’ is a narrow procedural disposition — it carries no assessment of infringement, patent validity, or claim construction. The phrase ‘in accordance with the Order entered on this date’ indicates a separate substantive order drove the dismissal, the contents of which are not reproduced in the public verdict record. For GSA, this provides immediate relief without res judicata protection against future claims on the same patent.
US11108397B2 — Fiber-Optic Connected Logic (FOCL) technology
US11108397B2 was filed as application US16/681744 and covers fiber-optic connected logic (FOCL) — a semiconductor interconnect architecture that uses optical fiber rather than conventional electrical pathways to connect logic components. FOCL technology is relevant to high-bandwidth, low-latency semiconductor designs and intersects with emerging co-packaged optics and photonic integration trends. The patent’s grant indicates the claims survived USPTO examination as novel and non-obvious.
FOCL-type architectures are gaining commercial relevance as data centre, HPC, and AI accelerator workloads push the limits of copper-based interconnects. A patent covering foundational aspects of fiber-optic logic connectivity could pose enforcement risk across a wide range of semiconductor and systems companies. The absence of any IPR or validity challenge to date means the patent’s claims have not been stress-tested against the prior art landscape — a strategically significant gap for potential defendants.
Should you run an FTO analysis against US11108397B2?
Any company developing, manufacturing, or commercialising products that incorporate fiber-optic connected logic — including co-packaged optics modules, photonic integrated circuits, and high-speed optical interconnect chiplets — should assess exposure to US11108397B2. The patent has not been invalidated, and this case ended without claim construction. If your architecture routes logic signals over optical fiber in ways that could read on the patent’s independent claims, FTO analysis is warranted.

What this case signals for the semiconductor interconnect IP landscape
A fast pro se dismissal rarely closes an IP story — especially when the underlying patent is uncontested on the merits.
Without-prejudice dismissals in pro se patent cases often precede re-filed actions
When individual inventors file pro se and face early dismissal, the cause is frequently procedural deficiencies — not a lack of substantive patent rights. Robinson retains US11108397B2 and the legal ability to re-file. Competitors and trade associations in the semiconductor interconnect space should monitor the patent and any continuation applications for renewed enforcement activity.
US11108397B2 has never been challenged on validity — a meaningful gap
No IPR, PGR, or district court invalidity ruling appears in the public record for this patent. This case was dismissed before any substantive defense was mounted. For companies developing or commercialising FOCL-adjacent technologies, the patent’s claims remain untested and potentially enforceable — warranting a proactive freedom-to-operate review.
Jr. v Global — key questions answered
Dismissed without prejudice means the court terminated Robinson’s infringement action on procedural grounds without ruling on the merits of the FOCL patent claim. Robinson retains the legal right to re-file a new action asserting US11108397B2, subject to applicable statutes of limitations and pleading requirements. No finding of infringement or invalidity was made.
Yes. The dismissal without prejudice did not invalidate or limit US11108397B2. The patent’s claims were never construed or challenged on their merits in this proceeding. The patent remains in force, and Robinson or any subsequent assignee could assert it in future litigation against GSA or other parties in the semiconductor interconnect space.
The 64-day duration and absence of recorded defendant counsel suggest the dismissal was procedural — potentially arising from deficiencies in the pro se complaint, failure to serve, or a court-initiated screening order. The public record does not specify the precise grounds. Cases involving pro se plaintiffs in patent matters are frequently dismissed at an early stage for failure to satisfy heightened patent pleading standards.
FOCL refers to an interconnect architecture in which optical fiber replaces conventional electrical conductors to carry signals between logic components on or between semiconductor devices. As AI, HPC, and data centre applications drive demand for higher bandwidth and lower latency, FOCL and co-packaged optics technologies are gaining commercial traction — making patents in this space increasingly strategically significant.
Yes, a dismissal without prejudice does not bar Robinson from re-filing. However, any new complaint would need to meet the pleading standards established under Twombly and Iqbal, comply with local patent rules in the chosen district, and be filed within the applicable statute of limitations. Individual GSA member companies could also potentially be named as defendants in a future action if their products implement FOCL-covered architectures.
