On August 2, 2022, Scientific Applications & Research Associates (SARA), Inc. filed a Complaint against Zipline International, Inc. in the United States District Court for the Northern District of California for patent infringement, trade secret misappropriation, and unfair competition, stemming from Zipline’s misappropriation and use of SARA’s proprietary acoustic “detect and avoid” (DAA) technology for unmanned aerial vehicles (UAV’s).


SARA developed a first-of-its-kind acoustic collision avoidance technology for UAV’s and filed for patent protection on October 17, 2007.  U.S. Patent No. 7,606,115, entitled “Acoustic Airspace Collision Detection System”, issued on October 20, 2009.  Since then, SARA has continued to enhance its acoustic DAA technology and has partnered with major players in the UAV industry.


Zipline’s announcement, on June 7, 2022, that it had developed an acoustic DAA system comes on the heels of its recent announcements of a partnership with Walmart for deployment of home delivery drone services and of having raised $250 Million of new funding at a valuation of $2.75 Billion.


SARA’s development of acoustic DAA technology is a historic achievement that will allow small UAV’s to operate as delivery vehicles in compliance with FAA regulations.  The lawsuit filed by SARA represents SARA’s commitment to steadfast protection of its intellectual property, and the hard work and innovation of its world class team of engineers. 


Scientific Applications & Research Associates (SARA), Inc. v. Zipline International, Inc., No. 3:22-cv-4480 (N.D. Cal.). 


SARA is being represented by Maynard Cooper & Gale LLP.

Aviation Week editors chose the Golden Horde team (led by SARA as the Prime Contractor) as one of four DoD winners of their Laureate Awards for extraordinary achievements embodying the spirit of exploration, innovation, and vision. The write-up states:

"Showing the potential to upend military thinking in a way not seen since the creation of precision-guided munitions, the Air Force Research Laboratory demonstrated swarming technology for networked munitions. Tests demonstrated how collaborating weapons could be redirected in flight, synchronized to impact simultaneously, and hit two separate targets."
