A five-member delegation led by Zhang Weibo, Deputy Head of the Chemical Invention Examination Department of the Patent Office, China National Intellectual Property Administration (CNIPA), and Wang Mingsong, Director of its Polymer Applications Division, recently visited ZYPEEK for a focused study of intellectual property practices. The delegation was accompanied by Sun Jian, Deputy Director of the Jilin Provincial Intellectual Property Centre.
ZYPEEK's Assistant to the Chairman, head of intellectual property, Research and Development Director and dedicated intellectual property engineer accompanied the visit and participated in the discussions.
PEEK Innovation and Intellectual Property Development
PEEK materials formed the industrial context for the visit. Established in 2006, Jilin Joinature Polymer Co., Ltd. (ZYPEEK) was listed on the STAR Market of the Shanghai Stock Exchange on 20 September 2023. The company specialises in the research, production and sale of polyether ether ketone (PEEK).
As of 30 June 2026, the company had obtained 44 domestic patents, including 31 invention patents, and seven international patents, including four invention patents, alongside multiple international certifications.
Industry Development, Patent Protection and Examination Services
The discussions focused on developments in the PEEK materials industry, the construction of corporate intellectual property systems and opportunities to improve patent examination services.
ZYPEEK introduced the characteristics of the PEEK industry and reviewed the company's development, current operations, strategic plans and competitive environment. The team outlined its technology development and intellectual property achievements, including the practical system used to protect its independently developed core technologies through patents.
The company also presented its approach to patent portfolio planning, patent licensing and transfers, intellectual property disputes, and the development of a specialist intellectual property team. Participants examined patent-related challenges in domestic and international markets.
With future technology development and upgrading in the PEEK industry in mind, the two sides exchanged views on patent examination standards in the polymer field, improvements to examination practices, and the commercialisation and use of patented achievements.
Practical Discussion and International Development
Dedicated discussions also addressed the drafting of formula-based patent claims, patent invalidation practice, overseas patent portfolio planning and applications, and cross-border intellectual property enforcement. Participants shared experience and discussed specific practical questions.
The visit provided professional guidance for addressing intellectual property challenges and improving the company's patent portfolio. ZYPEEK will continue to strengthen the standardisation and professional development of its intellectual property systems, combining protection and enforcement with risk management and the commercialisation of research results.
Through these efforts, the company aims to support the development of its international business and contribute to innovation and international development in the PEEK materials industry.
