???3. Canon

????Patents earned: 4,055

????Representative patent: "Focus Detection Apparatus"

????Country: Japan

????Camera king Canon leads the list for Japan, plunking down in third place. The company, which achieved a personal best of more than 4,000 patents, has been a mainstay in the top five of the annual list for nearly three decades. A majority of Canon's patents fall under the category of pictorial communication, which includes television. An example of one such patent blueprints a device "for performing automatic focus adjustment control effectively used with an imaging apparatus such as a video camera." That's one way Canon keeps new ideas in its line of sight.
