With the global importance of intellectual property rights, companies in order to retain their R&D energy and innovation, have patented to ensure and consolidate its intellectual property rights. The need to deal withmassive information will be very popular in these years. How to effectively and quickly conduct patent analysis and forecasting, will be the future trend. In this study, the contribution is: (1) providing a method for rapidly creating a technology-function matrix. So that the general patent analysts can efficiently produce analysis matrix. (2) Proposing three forecasting methods proven to compare their prediction accuracy of great reference value. Especially for the 5G communications technology, through patent information analysis in this study sample of fourth-generation LTE-A communication technologies can be discerned. The industry can take the lead in predicting future market trends and potential, and to plan in advance and layout ready to grab market niche.
