Research Of Patent Ontology Based Product Innovation Design Technology

Patent is the biggest information source in the world, which contains 90-95% world technology information. Patent information is contained in the patent literature on the application of patented inventions of the technical content, the scope of patent protection, who owns the patent and validity of the content of such information. Effective use of patent information will play a multiplier effect in product innovation design.This article will focus on the needs of product innovation design, establish the patent ontology to analyze and express the implicit innovation knowledge in patent literature, and explore the research of patent ontology based product innovation design technology by the support of TRIZ innovation theory.Firstly, the article establishes a patent ontology according to the patent features and needs of product innovative design. Then Raised patent ontology based product innovation design method by technical system evolution theory and conflict matrix theory, both of which are contained in TRIZ. According to this method, developing the support systems of patent ontology based product innovation design by ontology editing tools like protege. Lastly use the system to complete the development of new products.
