Patent Armory v. Hexagon Manufacturing Intelligence: Dismissed Without Prejudice in 64 Days
Patent Armory, Inc. asserted US7256899B1 — covering wireless methods and systems for 3D non-contact shape sensing — against Hexagon Manufacturing Intelligence in the Eastern District of Texas. The case closed just 64 days after filing when Patent Armory voluntarily dismissed all claims without prejudice, leaving the door open for future action.
A 64-day lifecycle: voluntary exit before Hexagon ever had to respond
On April 1, 2024, Patent Armory, Inc. filed suit against Hexagon Manufacturing Intelligence, Inc. in the Eastern District of Texas before Judge Rodney Gilstrap, asserting infringement of US7256899B1. The patent relates to wireless methods and systems for three-dimensional non-contact shape sensing — a technology domain central to metrology and industrial inspection products in which Hexagon is a globally recognised leader.
On June 4, 2024, just 64 days after filing, Patent Armory filed a Notice of Voluntary Dismissal Without Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court accepted and acknowledged the dismissal, mooting all pending relief requests. Because no answer or motion for summary judgment had been filed by Hexagon, Patent Armory was entitled to dismiss as of right — no court approval was required and no merits determination was made.
The speed of dismissal is notable: at 64 days, the case closed before Hexagon’s counsel of record even appeared in the docket. Without prejudice status means Patent Armory is not barred from reasserting the same patent against Hexagon or others. The public record is silent on whether a settlement, licensing agreement, or purely strategic recalibration drove the voluntary exit — all three scenarios are consistent with this procedural outcome.
Filing to Dismissed without Prejudice in 64 days
64 days — well below the median E.D. Tex. patent case duration, suggesting early strategic resolution
Voluntarily dismissed without prejudice: what that means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s right to dismiss before defendant answers
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the opposing party serves either an answer or a motion for summary judgment. That threshold had not been crossed here. The dismissal is therefore self-executing — the court’s order simply acknowledges and accepts the notice. No merits ruling was issued and no findings of fact or law were made.
No merits adjudicationWithout prejudice: the distinction that keeps litigation risk alive
A dismissal without prejudice does not extinguish the underlying claims. Patent Armory retains the right to refile against Hexagon, assert the same patent against other defendants, or revisit the dispute if licensing discussions fail. A dismissal with prejudice, by contrast, would have permanently barred the same claims. The public record here is silent on what — if anything — was agreed between the parties; the without-prejudice outcome alone cannot confirm or rule out a private settlement.
Right to refile preservedHexagon exits without conceding — but the patent remains enforceable
Hexagon Manufacturing Intelligence faces no adverse finding, no injunction, and no damages award. It never filed an answer or mounted an invalidity challenge, so US7256899B1 emerges from this litigation unchallenged and fully enforceable. Hexagon’s product lines in 3D metrology and non-contact scanning remain potentially within the patent’s scope unless it has secured a licence or successfully designed around the asserted claims.
No invalidity findingPatent survives intact — sector-wide exposure for 3D metrology players
Because no invalidity or non-infringement determination was made, US7256899B1 retains its full presumption of validity. Other manufacturers and integrators operating in wireless 3D non-contact shape sensing — including competitors in industrial metrology, coordinate measuring, and structured-light scanning — should treat this patent as an active enforcement risk. Patent Armory’s willingness to refile quickly in E.D. Tex. is consistent with an ongoing licensing campaign.

Official order — verbatim text
The court’s order is purely procedural: it accepts and acknowledges the Rule 41(a)(1)(A)(i) notice and denies all pending relief as moot. No claim construction, infringement finding, or validity ruling is embedded in the text. The phrase ‘dismissed without prejudice’ is the operative legal outcome — it confirms that Patent Armory’s claims are terminated for now, but not extinguished. Hexagon obtained no declaratory judgment and secured no IP clearance through this proceeding.
US7256899B1 — Wireless 3D Non-Contact Shape Sensing
US7256899B1 (application no. US11/538753) protects wireless methods and systems for three-dimensional non-contact shape sensing — technology that enables the acquisition of spatial geometry data without physical contact, transmitted over a wireless link. This places the patent at the intersection of metrology, machine vision, and wireless communication. The application number suggests a mid-2000s filing window, consistent with early commercial deployment of wireless portable measurement systems in industrial and manufacturing environments.
The commercial significance of this patent is amplified by the target defendant: Hexagon Manufacturing Intelligence is among the world’s largest suppliers of industrial metrology hardware, including portable arms, laser trackers, and structured-light scanners — many of which incorporate wireless data transmission. A valid, enforceable patent in this space has potential licensing leverage across a broad cohort of OEMs, integrators, and end-users in aerospace, automotive, and precision manufacturing. Patent Armory’s decision to assert in E.D. Tex. before Judge Gilstrap — a highly experienced patent jurist — is consistent with NPE enforcement strategy.
Should your team run an FTO check against US7256899B1?
Any R&D team or product manager building systems that capture three-dimensional geometry data wirelessly — including structured-light scanners, LiDAR-integrated platforms, wireless CMM arms, or cloud-connected metrology devices — should assess exposure to US7256899B1. The patent survived this litigation without any validity challenge, meaning its claims carry full legal weight. If your product transmits 3D shape data over a wireless interface, a formal FTO analysis is warranted before commercialisation or market entry.
PatSnap Eureka’s FTO Search Agent can map the claims of US7256899B1 against your product’s technical specifications, identify relevant prior art that could support an invalidity argument, surface any continuation or divisional applications in the same family, and flag other entities that have been targeted by Patent Armory.

What this case signals for the 3D metrology IP landscape
A 64-day lifecycle in E.D. Tex. with no defendant appearance typically signals either a licensing resolution or a strategic pivot — not surrender.
Without-prejudice dismissals in E.D. Tex. frequently precede refiling or licensing demands
Patent Armory’s early exit under Rule 41(a)(1)(A)(i) preserves maximum flexibility. In patent licensing campaigns, this pattern often indicates behind-the-scenes negotiations rather than a decision to abandon enforcement. Practitioners monitoring this docket should watch for a fresh complaint against Hexagon or parallel actions against other metrology OEMs asserting the same patent.
US7256899B1 remains fully valid and enforceable — FTO exposure is unchanged
No invalidity challenge was mounted and no claim construction occurred. The patent’s presumption of validity under 35 U.S.C. § 282 is entirely intact. Any company whose products involve wireless acquisition of 3D point-cloud or shape data should assess whether their design-arounds or licensing position adequately address the claims of US7256899B1.
Patent v Hexagon — key questions answered
Patent Armory, Inc. filed a patent infringement action against Hexagon Manufacturing Intelligence, Inc. in the Eastern District of Texas on April 1, 2024, asserting US7256899B1. On June 4, 2024, just 64 days after filing, Patent Armory voluntarily dismissed all claims without prejudice under Rule 41(a)(1)(A)(i). No merits ruling was issued and no answer was filed by Hexagon.
A dismissal without prejudice does not bar Patent Armory from reasserting US7256899B1 against Hexagon or any other defendant. The underlying claims are preserved. Patent Armory could refile in the same or a different district, or pursue licensing demands, without being foreclosed by this dismissal. A dismissal with prejudice would have permanently barred the same claims — that outcome did not occur here.
No. The case was dismissed before any substantive proceedings — no claim construction, validity analysis, or infringement finding occurred. US7256899B1 retains its full presumption of validity under 35 U.S.C. § 282. No court has ruled on the merits of Patent Armory’s infringement allegations against Hexagon’s products.
