As a leading global dedicated IC foundry service provider, TSMC continues pioneering advanced technology by investing considerable resources and efforts into technology development. To protect the Company's R&D achievements and strengthen its technology leadership, TSMC establishes a strong patent and IP management system, and works closely with various patent offices for technical exchanges and training, assisting patent examiners to achieve a better understanding about the Company's advanced technical contents and the patent examination process accelerating. The number of TSMC's patent applications in Taiwan has ranked first for three consecutive years. In addition, TSMC was ranked No. 6 among the 2018 US patent assignees according to IFI CLAIMS. The Company accumulates over 36,000 patent grants worldwide as of the end of June, 2019.


Close Ties with Domestic and International Patent Offices through Advanced Technology Trainings

TSMC has established a strong internal IP management system, which includes worldwide patent profiling strategy, in-depth invention mining for comprehensive protection, application monitoring throughout prosecution and regular patent landscape monitoring. TSMC has established a diversified reward system to encourage its employees to file their inventions, and has also built a robust patent and IP management system with a hierarchical review process to ensure the quality of patent applications.

Externally, TSMC works closely with both domestic and international patent offices, where the main markets of our products locate, through technical exchanges, to help patent examiners achieve a better understanding of the technical content that TSMC provided and accelerate the patent examination process. Those efforts will contribute to a high quality patent protection. For example, TSMC delivers speeches on advanced technology to the semiconductor group at USPTO Annual Tech Fair every year, which has attracted hundreds of patent examiners and their supervisors to join.

Visits by Patent Related Entities to TSMC

Unlike the fragmental knowledge described in the general patent specification, TSMC's sharing gave us a thorough understanding on the semiconductor's evolutionary toward 10 nanometer technology, which helps to create a better patent environment.
