NEC v. YI Technologies: Six-Patent AI Camera Dispute Dismissed With Prejudice
NEC asserted six AI vision and machine-learning patents against YI Technologies' full line of Kami and YI smart cameras, including fall-detection and cloud-monitoring products. Filed in E.D. Texas before Judge Rodney Gilstrap, the action ran 630 days before being dismissed with prejudice on NEC's unopposed motion, with each party bearing its own costs.
NEC's Six-Patent AI Camera Claim: How and Why It Ended
On 3 September 2024, NEC filed suit against YI Technologies, Inc. in the U.S. District Court for the Eastern District of Texas (Case No. 2:24-cv-00722), assigned to Judge Rodney Gilstrap. NEC asserted six United States patents — US10706336B2, US11373061B2, US11537814B2, US10223619B2, US10769468B2, and US10970995B2 — against an extensive range of YI and Kami branded smart camera products, including the Kami Indoor Camera, Kami Senior Care Camera, KamiCloud platform, Fall Detect by KamiCare, and at least twelve further devices.
The recorded basis of termination is Dismissed with Prejudice. The docket order states that the Court granted NEC's unopposed Rule 41(a)(2) motion to dismiss all claims with prejudice, with each party directed to bear its own costs and attorneys' fees. All pending requests for relief not explicitly granted were denied as moot, and the Clerk was directed to close the case. The specific terms underlying the parties' agreement are not disclosed in the available record.
The case ran approximately 630 days — nearly 21 months — before the voluntary dismissal with prejudice, suggesting substantive engagement between the parties before resolution. What drove the parties to this outcome, and whether any commercial arrangement was reached, is not disclosed in the public record. A dismissal with prejudice bars NEC from re-filing the same claims against YI Technologies on these six patents.

US10706336B2 — AI image recognition and smart camera analytics
Any company designing, manufacturing, or distributing AI-enabled cameras — including smart home cameras, outdoor security cameras, doorbell cameras, PTZ systems, or health-monitoring platforms with fall detection — should evaluate freedom-to-operate against NEC's six-patent family. This case demonstrates that NEC is actively enforcing these patents against a broad range of products in a plaintiff-friendly jurisdiction. The risk extends to cloud service providers supporting camera analytics and eldercare AI platforms.
Official order — verbatim text
The court's order granting NEC's unopposed Rule 41(a)(2) motion results in a dismissal with prejudice of all claims asserted by both parties. No substantive ruling on infringement, validity, or claim construction was made. The with-prejudice designation is legally significant: it operates as a final judgment on the merits for res judicata purposes, permanently barring NEC from reasserting these six patents against YI Technologies on the same facts.
Dismissed with prejudice: what the ruling means for both parties
Rule 41(a)(2) dismissal with prejudice explained
NEC filed an unopposed motion under Federal Rule of Civil Procedure 41(a)(2) asking the court to dismiss all claims with prejudice. Because the motion was unopposed, the court granted it without substantive analysis. A dismissal with prejudice is a final adjudication on the merits: NEC cannot re-file these same claims against YI Technologies under the six asserted patents in any future action.
Final — no re-filing permittedNEC relinquishes its infringement claims permanently
By securing a with-prejudice dismissal on its own motion, NEC voluntarily extinguished its right to pursue these six patent claims against YI Technologies. The patents themselves remain in force and enforceable against third parties — only the claims in this specific action against YI Technologies are barred. Whether NEC obtained any commercial benefit before filing the motion is not disclosed in the available record.
Patents survive; claims barred vs. YIYI Technologies walks away without a merits ruling
YI Technologies did not oppose the motion, obtaining closure of the litigation without a court ruling on validity or infringement of any of the six asserted patents. Each party bears its own costs and attorneys' fees per the court's order. The dismissal with prejudice provides YI Technologies a permanent shield against NEC re-asserting these specific claims — but no judicial finding of non-infringement or invalidity was made.
No merits ruling; costs absorbedAI camera sector: NEC's patent portfolio remains an enforcement risk
The six NEC patents cover AI-driven image recognition, object detection, and cloud analytics applied to smart cameras — a rapidly expanding product category. The with-prejudice dismissal resolves only the YI Technologies dispute. Other manufacturers of AI-enabled cameras, fall-detection systems, and cloud-based surveillance platforms remain exposed to these patents. Competitors and new entrants in this space should assess freedom-to-operate against NEC's portfolio.

R&D signals in the AI camera and computer vision patent space
Forward-looking patent intelligence derived from NEC v. YI Technologies — track portfolio trends, filing activity, and white space in AI-driven smart camera technology.
NEC's AI vision patent portfolio: depth and enforcement posture
NEC asserted six patents spanning multiple application generations in AI image recognition and cloud camera analytics. Monitoring NEC's continuation filings and new grants in this family can signal where the company is seeking to extend claim coverage — particularly relevant for companies developing next-generation on-device inference or edge AI camera systems.
NEC AI camera portfolioFiling trends: AI-powered fall detection and elder care monitoring
The inclusion of KamiCare fall detection among the accused products highlights a growing patent filing cluster around AI-based health monitoring through camera systems. R&D teams building eldercare, fall-detection, or ambient assisted living platforms should map the patent landscape before investing in this product category.
Fall detection AI patent trendsYI Technologies' patent position in the smart home camera market
YI Technologies operates across a wide smart camera product range — from budget indoor cameras to cloud analytics platforms — yet no defendant law firm or agent appears in the public record for this case. Understanding YI Technologies' own patent portfolio and defensive IP position can inform competitive intelligence for companies operating in the same Kami/YI product segment.
YI Technologies IP landscapeAdjacent white space: edge AI inference in low-power camera systems
NEC's asserted patents concentrate on recognition and analytics — but emerging white space exists in low-power edge AI inference architectures for battery-operated cameras (e.g., wire-free outdoor models), on-device privacy-preserving processing, and federated learning for camera networks. These areas may offer filing opportunities outside NEC's current claim footprint.

What this case signals for the AI camera and smart home IP landscape
Six patents, 17 products, and a 630-day run — this case maps the boundaries of NEC's AI vision enforcement strategy.
NEC's AI camera patents remain active enforcement tools against third parties
All six asserted patents — covering AI object recognition, fall detection, and cloud video analytics — survive this dismissal intact. Any camera or IoT platform company operating in the smart home or eldercare monitoring space should treat NEC's portfolio as an ongoing enforcement risk and conduct proactive FTO analysis.
E.D. Texas remains a go-to venue for AI camera patent assertions
NEC's choice of Judge Gilstrap's court in the Eastern District of Texas for a six-patent, multi-product AI camera dispute is consistent with the district's continued attractiveness for patent plaintiffs. Product companies facing assertion in this venue should prepare for expedited schedules and limited venue transfer success rates.
NEC v YI — key questions answered
NEC asserted six patents: US10706336B2, US11373061B2, US11537814B2, US10223619B2, US10769468B2, and US10970995B2. These patents relate to AI image recognition, object detection, and cloud-based camera analytics, and were asserted against a broad range of Kami and YI branded smart camera products and cloud services.
The case was dismissed with prejudice pursuant to NEC's unopposed Rule 41(a)(2) motion, granted by Judge Rodney Gilstrap on 26 May 2026. All claims asserted by the parties were dismissed with prejudice, with each party directed to bear its own costs and attorneys' fees. The specific terms underlying the parties' agreement, if any, are not disclosed in the available record.
A dismissal with prejudice is treated as a final judgment on the merits for res judicata purposes. NEC cannot re-file the same infringement claims against YI Technologies based on the six asserted patents and the same facts. However, the six patents themselves remain in force and NEC retains full rights to assert them against other defendants.
NEC accused a wide range of products including the Kami Indoor Camera, Kami Outdoor Security Camera, Kami Senior Care Camera, Kami Wire-Free Outdoor Camera, Kami mini, KamiCloud, Kami Doorbell Camera, Fall Detect by KamiCare, YI Dome 1080p Camera, YI Dome Guard 2K, YI Dome U Camera, YI Dome U Pro, YI Dome X Camera, YI Home 3 Camera, YI Outdoor 1080P PTZ Camera, YI Outdoor Camera, and YI Pro 2.
Yes. The dismissal with prejudice resolves only NEC's claims against YI Technologies. All six asserted patents — US10706336B2, US11373061B2, US11537814B2, US10223619B2, US10769468B2, and US10970995B2 — remain valid and enforceable against third parties. Companies manufacturing or selling AI-enabled cameras, fall-detection systems, or cloud video analytics platforms should conduct freedom-to-operate analysis against NEC's portfolio.
