Top company Trimble Navigation of Sunnyvale (NASDAQ: TRMB) joined the ranks of companies receiving FAA exemptions to use drones for commercial purposes this month. The exemption, called a Section 333 Exemption, brings Trimble and a number of engineering and infrastructure firms into a class that previously included a cohort of film production companies. Seven film companies have been granted FAA exemptions in 2014, beginning with six in September, thanks to efforts by the Motion Picture Association of America (MPAA). Many other leading multinational companies, ranging from Amazon to Domino's Pizza, have made strides in drone applications.
