VDPP v. Axis Communications: Voluntary Dismissal Without Prejudice After 147 Days
VDPP, LLC filed a patent infringement action against Axis Communications AB in the Eastern District of Texas, asserting two imaging and video processing patents. The case closed after just 147 days when VDPP voluntarily dismissed without prejudice under Rule 41(a)(1)(A)(i) — before Axis had answered or moved for summary judgment.
Early voluntary exit in E.D. Texas imaging patent dispute
On 6 September 2024, VDPP, LLC filed a patent infringement action against Axis Communications AB in the Eastern District of Texas before Judge Rodney Gilstrap. VDPP asserted two patents — US9716874B2 and US10021380B1 — covering technology relating to variable tint materials and continuous adjustable imaging filter systems, in connection with products described as faster state-transitioning 3Deeps filter spectacles using multi-layered variable tint materials. Axis Communications AB, a Swedish security camera and network video company, was the named defendant.
The case concluded on 31 January 2025 when VDPP filed a Notice of Voluntary Dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), dismissing all claims against Axis Communications without prejudice. The Court accepted and acknowledged the dismissal, directing the Clerk to close the case. Critically, Axis had not yet answered the complaint or moved for summary judgment at the time of dismissal, which is the procedural prerequisite enabling a plaintiff to dismiss unilaterally as of right under Rule 41(a)(1)(A)(i).
The 147-day duration suggests the case ended well before any substantive litigation activity such as claim construction or discovery. A without-prejudice dismissal preserves VDPP’s ability to refile identical claims, which may indicate ongoing negotiations, a strategic venue reconsideration, or a licensing discussion. The public record does not disclose whether any settlement or licensing agreement was reached, and the mutual cost-bearing order is consistent with a negotiated exit rather than a contested termination.

Dismissed without prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i) allows plaintiff to dismiss as of right
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss a case without a court order if the defendant has not yet served an answer or a motion for summary judgment. Axis had done neither, so VDPP held the unilateral right to dismiss. The Court’s order acknowledged — rather than granted — the dismissal, confirming it was self-executing.
Procedural dismissal — no merits rulingWithout prejudice: the door remains open for VDPP
A dismissal without prejudice means VDPP retains the right to refile the same claims on the same patents against Axis Communications in any competent court. No finding was made on infringement, validity, or claim scope. This contrasts with a dismissal with prejudice, which would bar VDPP from reasserting these patents against this defendant. The public record does not disclose whether a licensing deal or settlement was reached alongside the dismissal.
Refiling right preservedAxis escapes judgment — but faces ongoing exposure
Axis Communications obtained no invalidity finding, no non-infringement ruling, and no covenant not to sue. The without-prejudice dismissal means the same patents could be asserted again. Axis bears its own legal costs under the mutual cost order, consistent with an early exit before significant defence expenditure. However, the absence of any merits adjudication leaves Axis without estoppel protection against future assertion of US9716874B2 or US10021380B1.
No estoppel protection securedVariable tint imaging patents remain live enforcement risks
Because neither patent was adjudicated, both US9716874B2 and US10021380B1 remain enforceable assets in VDPP’s portfolio. Companies operating in network video, adaptive imaging, or variable-opacity optical systems — particularly those selling into the US market — should note that these patents survived this litigation cycle without a validity challenge. VDPP’s willingness to refile in E.D. Texas suggests continued enforcement intent.

Official order — verbatim text
The Court’s order confirms a procedurally clean dismissal: VDPP exercised its as-of-right entitlement under Rule 41(a)(1)(A)(i) before Axis had answered or moved for summary judgment. The phrasing ‘ACCEPTS AND ACKNOWLEDGES’ — rather than ‘GRANTS’ — is significant, confirming the dismissal was self-executing and required no judicial approval. The mutual cost-bearing order is standard in such exits and does not imply fault or settlement. No merits ruling was made on infringement or validity of either asserted patent.
US9716874B2 & US10021380B1 — variable tint imaging and optical filter technology
US9716874B2 (application no. US15/212114) and US10021380B1 (application no. US15/907614) cover technology described in connection with faster state-transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials. The patents sit at the intersection of adaptive optical systems and imaging signal processing — a domain with direct relevance to smart camera hardware, variable-opacity lens systems, and network video capture devices. US10021380B1 carries a B1 designation, indicating it issued without post-issuance amendment.
For companies in network video surveillance, adaptive imaging, or smart optical hardware — such as Axis Communications’ core product lines — these patents present a non-trivial claim scope risk. VDPP’s decision to assert both patents simultaneously is consistent with a portfolio enforcement approach, where parallel claims across related patent families increase the cost and complexity of an invalidity defence. Neither patent has been adjudicated on the merits in this proceeding, meaning their enforceability and claim scope remain untested in court.
Should you run an FTO against US9716874B2 and US10021380B1?
Any manufacturer or distributor of network video cameras, smart imaging systems, adaptive optical lenses, or variable tint display products with US market exposure should treat these two patents as live risks. VDPP’s without-prejudice dismissal preserves full enforcement rights, and the 3Deeps variable tint claim language may read on imaging components beyond the named defendant’s product range. R&D and product teams launching new camera or optical filter hardware should conduct FTO analysis before market entry.

Portfolio viewWhat this case signals for the imaging and network video IP landscape
An early voluntary exit in E.D. Texas — before answer — typically signals strategic repositioning, not retreat.
Without-prejudice dismissal is not the end of VDPP’s enforcement strategy
Rule 41(a)(1)(A)(i) dismissals before answer are often used as reset mechanisms — to change venue, consolidate cases, or finalise a licensing deal without court involvement. VDPP’s pattern of assertion in E.D. Texas and the short 147-day lifecycle suggests this case served a negotiation function rather than a full litigation campaign.
Axis holds no IP clearance — an FTO review of both patents is warranted
With no invalidity finding and no covenant not to sue, Axis Communications and any similarly positioned network video manufacturer retains full exposure to US9716874B2 and US10021380B1. Companies in adaptive imaging, smart camera, or variable-opacity optical systems should treat these patents as active risks requiring FTO analysis before expanding product lines.
VDPP’s two-patent portfolio structure suggests coordinated licensing pressure
Asserting two related continuation-style patents simultaneously is consistent with a portfolio licensing strategy designed to complicate invalidity challenges and increase settlement pressure. Firms receiving demand letters citing either US9716874B2 or US10021380B1 should map the full family before responding.
Judge Gilstrap’s docket creates predictable procedural leverage for plaintiffs
E.D. Texas under Judge Gilstrap moves on a compressed schedule. The ability to file, generate settlement pressure, and dismiss before answer — with no adverse cost order — is a well-documented tactic in this district. Defendants in similar actions should seek early claim construction guidance to neutralise this leverage before costs escalate.
VDPP v Axis — key questions answered
The dismissal without prejudice in Case No. 2:24-cv-00727 means VDPP, LLC retains the right to refile identical claims against Axis Communications on US9716874B2 and US10021380B1. No finding was made on infringement or validity. The dismissal was self-executing under Rule 41(a)(1)(A)(i) because Axis had not yet answered or moved for summary judgment.
The 147-day duration suggests the case ended before meaningful substantive litigation. VDPP filed the voluntary dismissal before Axis answered, which is consistent with a licensing negotiation, strategic venue reassessment, or a decision to consolidate enforcement efforts. The public record does not disclose the underlying reason for the early exit.
VDPP asserted two patents: US9716874B2 (application US15/212114) and US10021380B1 (application US15/907614). Both relate to variable tint optical filter technology and imaging systems, described in connection with continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials.
No. A dismissal without prejudice provides no estoppel protection. Axis received no covenant not to sue, no invalidity ruling, and no non-infringement finding. VDPP is legally free to refile claims based on US9716874B2 and US10021380B1 against Axis in any competent US court at a future date.
Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure allows a plaintiff to voluntarily dismiss a case without a court order if the defendant has not yet served an answer or a motion for summary judgment. In this case, Axis had done neither, so VDPP was entitled to dismiss as of right. The Court’s order acknowledged — rather than granted — the dismissal, confirming its self-executing nature.
