Journal of Networking Technology Jiang Chunlin, Jia Longchuan 9 4 2018 http://www.dline.info/jnt/fulltext/v9n4/jntv9n4_2.pdf Collaborative and cooperative networks exist in different domains and the strength of such networks has been increasing due to knowledge transfer and sharing process. In patent filing basically the participating groups work together in the technology development and consequently share the application and benefit transfer. In the last few years a large number of groups and companies form a network and work for patenting in OLED. It is evident that OLED scores over LED in many respects. We in this work intend to analyze the patent filing and patent networking among Chinese groups and companies. Using a patent dataset we studied the patent network. We found that the Chinese enterprises tend to have a strong chain of networks, have reasonable R & D network and participate in the OLED technologies.
