Baker Laser Technology v. Seiko Epson: Laser Projection Suit Dismissed With Prejudice
Baker Laser Technology, LLC filed suit against Seiko Epson Corporation in the Eastern District of Texas, asserting US9185373B2 over alleged infringement of laser projection system technology. The parties jointly stipulated to dismiss all claims with prejudice after just 168 days, with each side bearing its own costs.
A fast-resolved laser projection dispute in Judge Gilstrap’s court
On November 13, 2024, Baker Laser Technology, LLC filed a patent infringement action against Seiko Epson Corporation in the Eastern District of Texas (Case No. 2:24-cv-00924), presided over by Judge Rodney Gilstrap — one of the most active patent judges in the country. The sole asserted patent, US9185373B2 (application no. US14/562172), covers laser projection system technology, a field directly relevant to Seiko Epson’s commercial projector and display portfolio.
The case closed on April 30, 2025, when both parties filed a Joint Stipulation of Dismissal with Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Judge Gilstrap acknowledged and accepted the stipulation, formally dismissing all claims with prejudice. Crucially, no damages award or injunctive relief was ordered — the parties agreed to bear their own costs and attorneys’ fees, which is a standard commercial settlement posture.
At 168 days from filing to closure, the case resolved substantially faster than typical E.D. Texas patent litigation, which often extends well beyond a year before trial. The expedited resolution and mutual cost-bearing arrangement is consistent with a confidential settlement reached between the parties, though the public record does not disclose financial terms. What drove the resolution — claim strength, licensing discussions, or commercial dynamics — remains undisclosed.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii) — joint stipulation ends the case permanently
A dismissal with prejudice under Rule 41(a)(1)(A)(ii) requires agreement from all parties who have appeared. It is the most final of voluntary dismissal mechanisms: the plaintiff is barred from refiling the same claims against the same defendant. Judge Gilstrap’s order acknowledges the stipulation but does not adjudicate the merits — the court made no finding on infringement or validity.
No merits rulingBaker Laser cannot reassert these claims against Seiko Epson
By agreeing to dismissal with prejudice, Baker Laser Technology permanently relinquishes the right to pursue this specific infringement action against Seiko Epson on US9185373B2. This is a significant concession unless offset by undisclosed licensing terms. The patent itself remains in force and could theoretically be asserted against other parties, but this avenue is now closed.
Claims permanently barredSeiko Epson secures finality — but the patent survives
Seiko Epson exits the litigation without any adverse merits finding. The with-prejudice nature of the dismissal provides strong protection against re-litigation by Baker Laser on these specific claims. However, US9185373B2 remains a live patent asset that could be asserted by Baker Laser or any future assignee against other laser projection competitors.
No liability findingQuick resolution signals negotiated exit, not a fought defence
A 168-day resolution in E.D. Texas — before any substantive motion practice or claim construction — strongly suggests the parties reached a commercial understanding. The mutual cost-bearing provision is consistent with a licensing or covenant-not-to-sue agreement. Other laser projection system manufacturers should note that US9185373B2 remains active and Baker Laser’s litigation posture may continue.

Official order — verbatim text
The court’s order is purely procedural: Judge Gilstrap acknowledged and accepted the joint stipulation without making any finding on infringement or patent validity. The phrase ‘all claims in this case are DISMISSED WITH PREJUDICE’ forecloses Baker Laser from refiling against Seiko Epson on these specific claims, but does not reflect a merits adjudication. The cost-neutrality provision — each party bearing its own fees — is consistent with a negotiated exit rather than a clear-cut win for either side.
US9185373B2 — Laser Projection System Technology
US9185373B2 (filed under application number US14/562172) covers laser projection system technology — a field encompassing the optical, electronic, and control architecture used to generate and project laser-based images. Laser projection systems are deployed across commercial projectors, digital cinema, large-venue displays, and increasingly in automotive and AR/VR contexts. The patent’s grant represents a potentially broad asset in a sector where Seiko Epson is a major commercial player.
For the laser projection and imaging display sector, US9185373B2 represents an enforcement risk that extends beyond this single defendant. Baker Laser Technology’s willingness to file in E.D. Texas — a high-cost, high-risk venue for defendants — suggests confidence in the patent’s claim scope. Competitors offering laser projection products, digital projectors, or optically similar display systems should treat this patent as a live enforcement asset and assess their product architecture against its claims.
Should your team run an FTO against US9185373B2?
Any company designing, manufacturing, or distributing laser projection systems in the US should assess exposure to US9185373B2 following this litigation. The fact that Baker Laser pursued Seiko Epson — a tier-one projector manufacturer — and reached a rapid resolution suggests the patent may carry commercial licensing weight. Product teams developing laser light engines, projection optics, or image-rendering display hardware should flag this patent for review.

Baker v Seiko — key questions answered
The case was dismissed with prejudice by joint stipulation on April 30, 2025, under FRCP 41(a)(1)(A)(ii). No merits ruling was issued on infringement or validity. Each party bears its own costs and attorneys’ fees. Baker Laser Technology cannot refile these claims against Seiko Epson.
Baker Laser Technology asserted US9185373B2, filed under application number US14/562172, which covers laser projection system technology. The patent remains in force following the dismissal and could be asserted against other parties in the laser projection and display space.
Dismissal with prejudice under Rule 41 permanently bars Baker Laser Technology from reasserting the same claims against Seiko Epson. However, it does not invalidate US9185373B2. Baker Laser retains the patent and may assert it against other defendants, or license it to third parties.
At 168 days from filing to closure, the case resolved well below the typical E.D. Texas patent litigation timeline. The joint dismissal with prejudice and mutual cost-bearing terms are consistent with a confidential settlement or licensing agreement, though the public record does not confirm financial terms. Pre-litigation licensing discussions may also have accelerated resolution.
Yes. The dismissal only protects Seiko Epson. US9185373B2 remains an active patent and Baker Laser Technology has demonstrated enforcement intent in E.D. Texas before Judge Gilstrap. Other laser projection system manufacturers and adjacent display technology companies should conduct freedom-to-operate assessments against this patent.
