Lassen Peak Secures Foundational Patents for Handheld Terahertz Weapon Scanner, Strengthening Commercial Moat

New updates have been reported about Lassen Peak.

Lassen Peak has reinforced its commercialization strategy for the AirFrisk handheld concealed-weapon scanner by securing two additional U.S. patents that collectively lock down both the device architecture and its method of use, bringing the company’s total issued patents to six. The new apparatus patent (No. 12,332,342), granted in June 2025, protects the physical scanner and its proprietary single-chip radar design, while the method-of-use patent (No. 12,405,367), issued in September 2025, covers the operational process for non-invasive weapon detection at stand-off distances without physical contact. Together, these assets create a dual-layer intellectual property position that executives can view as a meaningful barrier to entry for competitors and a key value driver as Lassen Peak moves toward commercial deployment with law enforcement and public safety agencies. This portfolio builds on the company’s 10-year FCC Spectrum Horizons experimental license obtained in 2023 for the 280–320 GHz band, which provides an enabling regulatory framework for continued development, field testing, and early customer validation.

At the core of Lassen Peak’s offering is a battery-powered, handheld system operating at 304–311 GHz, in the true submillimeter-wave range that delivers sufficient resolution to distinguish weapons from benign items such as phones and wallets—capability typically associated with fixed, infrastructure-style screening systems. The company’s Radar System on Chip integrates a phased array with 24 receivers and 8 transmitters on a single die, programmable into 48–192 channel combinations, and uses coherent detection to enhance signal quality while staying within a mobile power envelope. Management describes this combination of chip-level integration, AI-enabled imaging, and submillimeter-wave operation as the technical foundation that makes the form factor and use case viable, positioning AirFrisk as personal field equipment rather than a gate-based checkpoint solution. To address regulatory and reputational risk around civil liberties, Lassen Peak has added constitutional rights expert Scott Greenwood, former ACLU General Counsel Emeritus and a policing best-practices leader, to its board to guide deployment standards and mitigate legal exposure for agencies. For investors and potential partners, the patents, spectrum access, and governance structure collectively signal a maturing platform with defensible IP, a defined regulatory pathway, and a clear strategy to integrate advanced sensing technology into frontline public safety operations.
