Abstract

[Purpose/Significance] Under the background of economic globalization and production globalization, the filing of patent invalidation requests is a common means to obstruct the international patent layout and strategic implementation of competitive enterprises. Studying the key factors influencing the tendency of patent invalidation requests in the United States and analyzing their operation mechanism aims to help Chinese enterprises better understand the risks of patent invalidation requests, take corresponding measures to reduce the probability of patent invalidation requests, protect their technological innovation achievements, and enhance their competitiveness in the international market. [Method/Process] Taking the data of patent invalidation litigation in the United States as the research object, the key factors that cause patent invalidation requests were identified from five dimensions: patent relevance, legal stability, technical value, market value and industrial field. On this basis, the interactive relationship between various factors and the mechanism of patent invalidation requests were analyzed by constructing a structural equation model. [Result/Conclusion] The results show that legal stability, market value and industrial field will directly affect the occurrence probability of invalidation requests, while there is an indirect relationship between patent relevance and technical value and the occurrence of invalidation requests.

Key words： American invention patent; the tendency of patent invalidation request; key influencing factors; operation mechanism; structural equation model
