Engajer Inc. v. Microsoft Co. — Dismissed Without Prejudice (63 Days)
Engajer Inc. filed a patent infringement action against Microsoft in the Southern District of Florida, asserting US10956965B1 covering interactive marketing presentation technology. The case was dismissed without prejudice in just 63 days — not on the merits, but because Engajer, as a corporate entity, failed to obtain licensed counsel eligible to practice in the district.
A procedural dismissal before Microsoft ever answered on the merits
On 12 March 2025, Engajer Inc. filed a patent infringement action against Microsoft Co. in the U.S. District Court for the Southern District of Florida (Case No. 9:25-cv-80339), asserting U.S. Patent No. 10,956,965 B1. The patent relates to providing webpages used to configure interactive marketing presentations over a network — a technology domain directly relevant to cloud-based marketing and presentation platforms.
The case closed on 14 May 2025, just 63 days after filing. The dismissal was without prejudice, entered after the court accepted a Magistrate’s Report and Recommendation. The operative reason was not a substantive deficiency in Engajer’s patent claims, but a procedural one: as a corporate entity, Engajer was required to be represented by licensed counsel eligible to practice in the Southern District of Florida — a requirement it had not satisfied.
The court was explicit that nothing in its order should be construed as an indication of the merits of Engajer’s claims, leaving the door open for refiling once proper counsel is secured. The 63-day resolution suggests the representation defect was identified early — likely flagged at or shortly after the initial case management stage. Whether Engajer intends to refile with counsel, and what response Microsoft might mount on the merits, remains unknown from the public record.

Dismissed without prejudice: what this ruling means for both parties
Corporate entities cannot self-represent in federal court
Under long-standing federal precedent, a corporation — unlike a natural person — cannot appear pro se in federal court. It must be represented by a licensed attorney. The Southern District of Florida’s dismissal reflects this rule: Engajer’s failure to obtain eligible counsel rendered the action procedurally defective. The court accepted the Magistrate’s Report and Recommendation and closed the case on this basis alone.
Procedural — no merits adjudicatedWithout prejudice: Engajer can refile — but timing matters
A dismissal without prejudice means the case is terminated but Engajer’s claims are not extinguished. The court expressly confirmed Engajer may initiate a new action after obtaining eligible counsel. However, refiling introduces risks: statutes of limitations continue to run, and any delay in securing counsel and refiling could affect the damages window or create estoppel arguments. The public record does not disclose whether Engajer has retained counsel since dismissal.
Refiling permitted with counselMicrosoft escapes without a merits ruling — for now
Microsoft faces no finding of infringement, invalidity, or any substantive determination regarding US10956965B1. All pending motions were denied as moot, meaning Microsoft’s litigation exposure on this patent has not been resolved — only deferred. If Engajer refiles with counsel, Microsoft will need to respond on the merits. The procedural dismissal provides no precedential shield against a properly filed future action asserting the same patent.
No merits shield — exposure persistsInteractive marketing patent remains live and unadjudicated
US10956965B1 has not been invalidated, narrowed, or found unenforceable. Any competitor operating in the interactive marketing presentation or network-configured presentation technology space should treat this patent as an active enforcement risk. The procedural dismissal offers no comfort on infringement exposure. Companies developing or deploying configurable web-based marketing presentation tools should conduct freedom-to-operate analysis against this patent.

Official order — verbatim text
The court’s order is unambiguous that the dismissal carries no merits weight: point 3 explicitly states nothing should be construed as an indication of the merits of Engajer’s claims. The operative basis was the corporate representation rule — not claim invalidity, non-infringement, or any substantive patent law doctrine. For Microsoft, this means no collateral estoppel protection. For Engajer, the patent’s enforceability and claim scope remain entirely intact, and the dismissal functions as a procedural reset rather than a defeat.
US10956965B1 — Interactive marketing presentation configuration technology
U.S. Patent No. 10,956,965 B1, filed under application number US15/424763, covers technology for providing webpages that enable users to configure interactive marketing presentations delivered over a network. The patent sits at the intersection of web application design and digital marketing infrastructure — a domain that has grown significantly with the proliferation of cloud-based SaaS platforms. The granted patent number suggests it issued from a relatively mature prosecution process.
Strategically, this patent is relevant to any platform that enables users to build, configure, or deploy interactive presentations or marketing experiences via a browser-based interface. That description encompasses a wide range of products across the enterprise SaaS, marketing technology, and cloud productivity sectors. The patent has not been subjected to IPR or any merits-based court challenge to date, meaning its claims remain unscrutinised in adversarial proceedings — a factor that elevates FTO risk for competitors.
Should your product team run an FTO against US10956965B1?
Any organisation developing or commercialising web-based tools that allow users to configure and deploy interactive marketing presentations should conduct a freedom-to-operate assessment against US10956965B1. This is particularly relevant for SaaS marketing platforms, cloud productivity suites with presentation or content creation features, and digital experience platforms. The patent’s claims have not been narrowed by litigation or IPR — they stand as granted.
PatSnap Eureka’s FTO Search Agent can map the claim language of US10956965B1 against your product’s technical architecture, surface potentially conflicting claim elements, and identify prior art that could support a validity challenge if needed. Given that this patent remains unadjudicated on the merits, early FTO work is the lowest-cost risk management step available to product and IP teams operating in the interactive marketing technology space.

What this case signals for the interactive marketing IP landscape
A procedural dismissal against a tech giant still leaves a live patent in play — and signals how assertion strategy could evolve.
Pro se corporate filings fail at the threshold — every time
Federal courts consistently require corporate plaintiffs to retain licensed counsel. Patent owners operating without in-house legal resources should treat counsel retention as a prerequisite to filing, not an afterthought. A dismissed case still consumes resources and may reset litigation momentum.
Without prejudice dismissal leaves US10956965B1 as an active threat
The court’s express confirmation that no merits determination was made preserves Engajer’s enforcement position. Competitors in configurable web-based marketing presentation technology — particularly cloud platform operators — should not assume this case closed the matter. An FTO analysis against US10956965B1 remains prudent.
Engajer v Microsoft — key questions answered
The case was dismissed without prejudice because Engajer Inc., as a corporate entity, failed to obtain licensed counsel eligible to practice in the Southern District of Florida. Federal courts require corporations to be represented by an attorney — they cannot appear pro se. The court accepted the Magistrate’s Report and Recommendation on this basis and expressly stated no merits determination was made.
No. The court explicitly stated that nothing in its dismissal order should be construed as an indication of the merits of Engajer’s claims. US10956965B1 was not found invalid, unenforceable, or not infringed. The patent remains fully granted and unadjudicated on the merits, preserving Engajer’s ability to assert it in future litigation.
Yes. A dismissal without prejudice does not extinguish the underlying claims. The court’s order expressly confirmed that Engajer may initiate a new action once it obtains eligible counsel. However, refiling carries practical risks including the running of statutes of limitations and a narrower damages window, so timing and counsel selection will be strategically significant.
US10956965B1 covers providing webpages used to configure interactive marketing presentations over a network. This claim scope is potentially relevant to Microsoft’s cloud and productivity products — including tools that enable web-based configuration of presentation or marketing content. Because no merits ruling was made, Microsoft’s exposure under this patent remains unresolved.
In U.S. patent litigation, a dismissal without prejudice terminates the current action but leaves the plaintiff’s substantive claims intact. The plaintiff may refile the case, subject to applicable statutes of limitations and court rules. It is procedurally distinct from a dismissal with prejudice, which bars refiling of the same claims. In this case, the dismissal was purely procedural — no patent law merits were adjudicated.
