Kephart Consulting v. RealNetworks SAFR: Facial Recognition Patents Dismissed Without Prejudice
Kephart Consulting, LLC filed suit against RealNetworks, LLC — operating as SAFR — in the Southern District of New York, asserting two computer vision and facial recognition patents. The case closed in just 58 days via a voluntary dismissal without prejudice, leaving both asserted patents fully alive for future enforcement.
Early voluntary exit leaves SAFR’s facial recognition exposure unresolved
On January 15, 2025, Kephart Consulting, LLC filed a patent infringement action against RealNetworks, LLC d/b/a SAFR in the U.S. District Court for the Southern District of New York before Judge Jessica G. L. Clarke. The complaint asserted two patents — US10796137B2 and US10248849B2 — directed at computer vision, facial recognition, and related processing systems, targeting RealNetworks’ SAFR platform and its associated devices, methods, and processor-readable media.
The case closed on March 14, 2025 — just 58 days after filing — when Kephart Consulting filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), available as of right where the defendant has not yet answered or moved for summary judgment. Critically, Kephart expressly designated the dismissal as without prejudice as to the asserted patents, meaning the patents survive and may be re-asserted in a future action. Each party was ordered to bear its own costs and attorneys’ fees.
A 58-day lifecycle is notably short even for pre-answer dismissals, suggesting the parties may have reached a private arrangement, that Kephart reassessed its claim strength after filing, or that strategic timing considerations — such as claim mapping refinement or forum selection review — prompted the withdrawal. The public record is silent on any settlement terms. Because the dismissal is without prejudice, RealNetworks cannot treat this as a final resolution of its exposure under either asserted patent.

Voluntarily dismissed without prejudice: what this means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right, no court order needed
Federal Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order at any time before the defendant has served an answer or a motion for summary judgment. Kephart exercised this right unilaterally. The rule is purely procedural — it carries no merits determination and leaves no adverse judgment on record. The court played no adjudicatory role in the outcome.
No merits adjudicationPatents survive: Kephart retains full right to re-file
A dismissal without prejudice does not extinguish the underlying claim. Kephart explicitly stated the dismissal is ‘without prejudice as to the asserted patents,’ meaning US10796137B2 and US10248849B2 remain fully enforceable. Kephart may re-file against RealNetworks SAFR — or any other party — at a later date, subject to the applicable statute of limitations. This is materially different from a dismissal with prejudice, which would bar re-filing on the same claims.
Patents remain liveRealNetworks SAFR faces unresolved patent exposure
RealNetworks secured no invalidity ruling, no non-infringement finding, and no covenant not to sue. Its SAFR platform remains potentially exposed to re-assertion of both patents. Because the defendant had not yet answered, it incurred no substantive litigation costs in defending the merits. However, the lack of a with-prejudice dismissal or a license means SAFR’s IP risk management team should treat this as an open matter requiring continued monitoring.
Exposure unresolvedFacial recognition sector: litigation risk remains live
Companies deploying AI-driven facial recognition and computer vision systems — including identity verification, access control, and surveillance platforms — should note that neither asserted patent has been invalidated or licensed through this action. The without-prejudice dismissal is consistent with a strategic pause rather than a genuine resolution. Competitors operating in the SAFR product space should conduct FTO reviews against US10796137B2 and US10248849B2 before product launch or expansion.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly designates the withdrawal as without prejudice to the asserted patents. This phrasing is legally significant: it forecloses any argument that the claims were resolved on the merits or that Kephart waived its enforcement rights. The costs-each-party provision is standard for pre-answer Rule 41 dismissals and does not indicate a negotiated resolution. No invalidity, non-infringement, or unenforceability determination was made with respect to US10796137B2 or US10248849B2.
US10796137B2 & US10248849B2 — Facial Recognition and Computer Vision Systems
US10796137B2 (application US16/372346) and US10248849B2 (application US15/716355) are U.S. utility patents directed at computer vision and facial recognition technologies, covering devices, methods, systems, and processor-readable media. The patents’ application numbers suggest sequential development across the 2017–2019 filing window, a period of rapid commercial deployment of AI-driven identity systems. The claims encompass processor-implemented recognition workflows relevant to real-time facial analysis platforms such as SAFR.
Both patents sit at the intersection of machine learning-enabled image processing and identity verification — one of the most actively litigated and commercially contested technology areas in current IP practice. Any company offering facial recognition, access control, or biometric authentication software operating on devices or in the cloud should treat these patents as active risk vectors. The without-prejudice dismissal of this action means neither patent has been narrowed, invalidated, or licensed through this proceeding, preserving full enforcement leverage for the patent holder.
Should you run an FTO against US10796137B2 and US10248849B2?
R&D teams and product counsel at companies building or deploying facial recognition, biometric authentication, or computer vision pipelines — including access control, identity verification, surveillance analytics, and edge AI devices — should treat these two patents as active clearance items. The without-prejudice dismissal against SAFR means no claim scope has been adjudicated, leaving the full breadth of both patents available for assertion against third parties.

What this case signals for the computer vision and facial recognition IP landscape
A 58-day voluntary dismissal without prejudice rarely signals the end of a patent dispute — it often marks a tactical reset.
Without-prejudice dismissals often precede re-filing or licensing pressure
Patent plaintiffs who dismiss under Rule 41(a)(1)(A)(i) retain all future optionality. This pattern is consistent with a plaintiff reassessing forum, refining claim charts, or pursuing a negotiated licence before committing to full litigation cost. RealNetworks should not treat this closure as permanent resolution of its exposure under either asserted patent.
Each-party-bears-own-costs signals no settlement payment was recorded
The express costs-each-party term in the dismissal notice suggests no monetary settlement was memorialised in the public filing. That said, private side agreements are not required to be filed. IP teams monitoring this case should note the public record is silent on any licence grant or royalty payment — the absence of evidence is not evidence of absence.
Kephart v RealNetworks — key questions answered
A without-prejudice dismissal under Rule 41(a)(1)(A)(i) means Kephart retains the right to re-file suit against RealNetworks or any other party for infringement of US10796137B2 and US10248849B2. No merits ruling was made, no invalidity finding issued, and no covenant not to sue was recorded in the public docket. The patents remain fully enforceable.
Kephart Consulting asserted two patents: US10796137B2 (application US16/372346) and US10248849B2 (application US15/716355). Both cover computer vision, facial recognition, and related processing systems, methods, and processor-readable media. The accused product was RealNetworks’ SAFR AI facial recognition platform.
The public record does not disclose the reason for the rapid dismissal. Possible explanations include early settlement or licensing discussions not memorialised in public filings, Kephart reassessing its claim mapping or litigation strategy, or a strategic decision to refile in a different forum or with a refined complaint. The costs-each-party term is consistent with a mutual agreement to stand down rather than a plaintiff concession.
Federal Rule of Civil Procedure 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order before the defendant serves an answer or a motion for summary judgment. In this case, RealNetworks had not yet answered, so Kephart could file a unilateral notice of dismissal. The rule is procedural only — it carries no merits determination and requires no judicial approval.
Yes — indirectly. Because the dismissal is without prejudice and no invalidity ruling was issued, US10796137B2 and US10248849B2 remain live enforcement tools against any party whose products fall within the claim scope. Companies building facial recognition, biometric authentication, or computer vision systems should conduct FTO reviews against both patents regardless of this case’s outcome.
