2014年获得技术专利最多的8大公司

    3. 佳能

    专利数量：4055项

    代表性专利：“焦点检测装置”

    国家：日本

    相机之王佳能位列第三，是排名最高的日本公司。该公司获得超过4000项专利，创下历史新高。近30年来，佳能一直稳居该年度榜单的前五名。佳能的专利主要为图像通信类，包括电视。其中一项专利构想了一种能够“通过使用视频摄像头等成像装置，有效执行自动调焦控制”的设备。佳能正是通过这种方式不断创新。

   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.
