This paper analyzed the current situation of ultrasonic fingerprint recognition patent application in the whole world, such as application trend, patent layout, innovation entity, technical branch, and the applicant constitution. This paper aimed to offer technical information for technician, and present patent information for enterprise. According to the forehead analysis, ultrasonic fingerprint recognition field is an intensely competitive market, the Chinese and American markets are hotter,where the resource centralized. The number of patents filed in China is the most in the world, proving China's strong research and development strength. The Chinese enterprise O-film has the most application in the world, which focused on module packaging. The most important part of the industrial chain is sensor. Those successful algorithms belong to a handful of enterprises.
