Kephart Consulting v. AxxonSoft US: Security Patent Suit Dismissed Without Prejudice
Kephart Consulting, LLC filed suit against AxxonSoft US, Inc. in the Northern District of California, asserting two patents covering techniques for providing security to monitored areas. After 250 days, Kephart voluntarily dismissed all claims without prejudice before AxxonSoft filed any answer — leaving the door open for future litigation.
Early voluntary exit leaves AxxonSoft exposure unresolved
On 26 September 2024, Kephart Consulting, LLC — a patent licensing entity represented by Ramey LLP — filed an infringement action against AxxonSoft US, Inc. in the United States District Court for the Northern District of California (Case No. 4:24-cv-06770), assigned to Judge Kandis A. Westmore. The suit asserted two patents: US10796137B2 and US10248849B2, both directed to techniques for providing security and area surveillance, against AxxonSoft’s video management and security software products.
On 3 June 2025 — approximately 250 days after filing — Kephart filed a notice of voluntary dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i), dismissing all claims without prejudice. The dismissal was expressly stated to be without prejudice as to both asserted patents, with each party bearing its own costs. Because AxxonSoft had not yet answered or filed a motion for summary judgment, Kephart was entitled to dismiss as of right, requiring no court order.
The sub-nine-month resolution is notably swift for patent litigation in the Northern District of California, suggesting the parties may have reached an accommodation outside the public record, or that Kephart chose to withdraw strategically — perhaps pending claim refinement or to pursue alternative defendants. The public record does not disclose any settlement agreement or licensing terms. The without-prejudice dismissal means Kephart could refile against AxxonSoft on the same patents, subject only to statute of limitations constraints, leaving AxxonSoft’s exposure technically unresolved.

Voluntarily dismissed: what the without-prejudice exit means for both parties
Rule 41(a)(1)(A)(i) dismissal: a right, not a concession
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action as of right — without a court order — provided the defendant has not yet served an answer or motion for summary judgment. AxxonSoft had done neither, so Kephart’s notice was self-executing. This procedural posture means no merits determination was made; the court issued no ruling on infringement, validity, or claim construction.
No merits ruling enteredWithout prejudice: Kephart preserves the right to refile
The dismissal is expressly without prejudice as to the asserted patents. This is legally significant: Kephart is not barred from reasserting US10796137B2 or US10248849B2 against AxxonSoft in a future action, subject to the six-year statute of limitations for patent damages. The public record does not disclose whether a confidential settlement or licensing agreement accompanied the dismissal — that question remains open.
Refiling remains possibleAxxonSoft escapes judgment — but not permanently
AxxonSoft US obtained a clean exit from this action at an early stage without incurring a merits ruling against it. However, because the dismissal is without prejudice, the company cannot treat this as a final resolution of its patent exposure on the asserted claims. AxxonSoft should treat the dismissed patents as live enforcement risks until they expire, are invalidated, or a licence is confirmed.
Exposure persists post-dismissalSecurity software vendors face recurring NPE assertion risk
The filing pattern — early assertion, pre-answer dismissal, without-prejudice exit — is consistent with NPE licensing campaigns where initial suits are used to gauge defendant posture or secure licence discussions. Video management and physical security software vendors operating in the U.S. market should map their products against US10796137B2 and US10248849B2, as the same patents may be asserted again against AxxonSoft or deployed against competitors.

Official order — verbatim text
The dismissal notice invokes FRCP 41(a)(1)(A)(i) and expressly specifies that dismissal is without prejudice as to the asserted patents, with costs split. This language forecloses any inference of a merits concession by either party. Critically, the without-prejudice designation keeps both US10796137B2 and US10248849B2 live as enforcement assets. The cost-splitting provision is standard for Rule 41 voluntary dismissals and does not imply any monetary settlement or damages award.
US10796137B2 & US10248849B2 — Security Area Monitoring Techniques
US10796137B2 (App. No. 16/372346) and US10248849B2 (App. No. 15/716355) both relate to techniques for providing security surveillance to defined areas. The patents sit within the physical security and intelligent video analytics domain — a sector experiencing rapid growth driven by AI-enhanced monitoring, smart camera networks, and cloud-based video management systems. The application filing dates suggest these patents cover methods and systems for automated security event detection and area protection.
For video management software vendors, these patents represent a meaningful assertion risk. AxxonSoft’s product line — which includes AI-driven video analytics and physical security management — maps directly to the technical domain described in the asserted claims. With the without-prejudice dismissal preserving Kephart’s enforcement rights, competitors offering similar intelligent surveillance software in the U.S. market should treat both patents as live risks, particularly those commercialising AI-powered anomaly detection, perimeter monitoring, or access control integration features.
Should you run an FTO analysis against US10796137B2 and US10248849B2?
Any company developing or commercialising video management software, intelligent surveillance systems, or AI-driven physical security platforms in the U.S. market should conduct a freedom-to-operate analysis against both asserted patents. The without-prejudice dismissal of this action means Kephart Consulting retains full enforcement rights — and the filing pattern is consistent with a broader NPE assertion campaign targeting security software vendors.

What this case signals for the video security software IP landscape
A pre-answer voluntary dismissal in N.D. Cal. rarely represents a clean win for either side — it most often signals ongoing negotiations or strategic repositioning.
Without-prejudice dismissal is not closure — monitor for refiling
Kephart retains full rights to reassert US10796137B2 and US10248849B2 against AxxonSoft or any other security software provider. Any competitor operating in the physical security and video surveillance software space should treat these patents as active enforcement assets and track Kephart’s litigation docket for follow-on actions.
Pre-answer dismissals in NPE cases often follow off-record resolution
The 250-day window between filing and Rule 41 dismissal is consistent with early-stage licensing discussions. Whether a licence was granted to AxxonSoft is not publicly disclosed. Security software vendors facing similar claims from Kephart Consulting should investigate whether a licensing programme exists before incurring full defence costs.
Kephart v AxxonSoft — key questions answered
Kephart Consulting, LLC filed a patent infringement suit against AxxonSoft US, Inc. in the Northern District of California on 26 September 2024, asserting US10796137B2 and US10248849B2. On 3 June 2025, Kephart voluntarily dismissed all claims without prejudice under FRCP 41(a)(1)(A)(i), with each party bearing its own costs. No merits ruling was issued.
A without-prejudice dismissal does not resolve the underlying infringement claims. Kephart retains the right to refile suit against AxxonSoft on US10796137B2 and US10248849B2 within the applicable six-year damages window. AxxonSoft received no invalidity ruling, no non-infringement finding, and no covenant not to sue — meaning its exposure on these patents remains legally unresolved.
Kephart asserted two U.S. patents: US10796137B2 (App. No. 16/372346) and US10248849B2 (App. No. 15/716355). Both patents are directed to techniques for providing security to monitored areas — a technical domain that encompasses video analytics and physical security software, the core of AxxonSoft’s product portfolio.
Several strategic reasons are possible: the parties may have reached a private licensing or settlement agreement not reflected in the public record; Kephart may have chosen to withdraw to refine its claim charts or pursue other defendants first; or the filing may have been part of a broader licensing campaign where early dismissal preserves optionality. The public record does not confirm which scenario applies here.
Kephart Consulting was represented by Ramey LLP (William Peterson Ramey III) and Jennifer Ishimoto, alongside Susan S.Q. Kalra. AxxonSoft US was represented by Delahunty & Nash LLP (Micah David Nash) and Sughrue Mion PLLC (William H. Mandir and Peter S. Park). Ramey LLP is a known plaintiff-side patent litigation firm with an active NPE docket.
