This research focuses on joint patent applications which have been produced from joint Research & Development (R&D) collaborations. There has been limited past research in this area. This research compares and analyses joint patent applications from Japan, US and Europe, clarifying the differences and features for successful joint R&D through statistical analysis between these regions. The most important factors are the field of technology, the situation of cooperation, the difference of patent law and its practice in each region, the conditions of the joint R&D agreement, and the strategy for joint R&D. A conclusion will be drawn: The more advantageous the regulation of co-owned patents is, the greater the number of joint patent applications is filed in that country's patent office.
