Lassen Peak Secures Foundational Patents for Handheld Terahertz Weapon Scanner

New updates have been reported about Lassen Peak.

Lassen Peak, Inc. has strengthened its commercialization prospects for the AirFrisk handheld concealed weapon scanner with two new U.S. patents that collectively secure both the device’s architecture and its method of use, bringing the company’s total issued patents to six. Patent No. 12,332,342 covers the physical apparatus, including a proprietary single-chip radar design, while Patent No. 12,405,367 protects the operational process for non-contact, stand-off detection of concealed weapons, creating a layered IP position that management describes as a commercial moat for investors and future law enforcement customers. These patents build on a 10-year FCC Spectrum Horizons experimental license awarded in early 2023 for operation in the 280-320 GHz band, enabling ongoing field testing and development at true submillimeter-wave frequencies that can differentiate weapons from benign items such as phones and wallets.

AirFrisk is engineered as a field-portable, battery-powered device rather than fixed infrastructure, aiming to become standard issue personal equipment for officers, comparable to body cameras or conducted energy devices. The system is driven by a proprietary radar system-on-chip integrating a phased array of 24 receivers and 8 transmitters, configurable into up to 192 transmit/receive combinations, with coherent detection to enhance signal-to-noise performance at low power levels suitable for handheld use. Co-founders CEO Hatch Graham and Chief Scientist Dr. Ehsan Afshari emphasize that the patents protect the core innovation of coherent radar above 300 GHz on a single chip, which underpins both imaging resolution and safety characteristics. To manage legal and reputational risk as the technology moves toward deployment, Lassen Peak has also assembled governance expertise around civil liberties, including board member Scott Greenwood, a prominent constitutional rights attorney and former ACLU general counsel, to help ensure the product’s use aligns with constitutional policing standards and mitigates liability for adopting agencies.
