Mr. Zhang Jie previously worked at the Mechanical Invention Examination Department of the China Patent Office. In 1997, he founded Sanju Environmental Protection, and in 2000, he established Sanju Sunshine Intellectual Property Agency. Sanju Environmental Protection successfully listed on the Growth Enterprise Market in 2010 and became a well-known company in the fields of energy purification and bioenergy.

After stepping down from all positions at Sanju Environmental Protection in 2011, he devoted all his efforts to the development of Sanju Sunshine, serving as Chairman of Beijing Sanju Sunshine Intellectual Property Service Group Co., Ltd. He worked tirelessly to build Sanju Sunshine into “the most respected intellectual property service organization,” one that can truly provide protection and support for corporate technological innovation.

After years of development, Sanju Sunshine has become a comprehensive organization providing services in the full spectrum of intellectual property industries, including rights applications, litigation protection, consulting research, IP operation, and innovation investment. It is ranked among Beijing's Top 100 Self-Owned Brands in the Business Service Industry, recognized as one of the first “National Intellectual Property Service Brand Institutions” by the State Intellectual Property Office, and one of the first “Demonstration Units for Intellectual Property Analysis and Evaluation Services.”

Mr. Zhang Jie has over 30 years of experience in intellectual property. He has witnessed the rapid development of China’s intellectual property industry and has been directly involved in the growth of Sanju Sunshine.

As a senior patent agent, with his professional perspective and judgment, he has helped Chinese corporate clients develop top-level litigation strategies and effective litigation technical measures. This has effectively solved the intellectual property challenges faced by these companies, promoting their healthy growth.

Representative cases include the patent invalidation and litigation case between Hanwang Technology and Japan’s WACOM, the “World’s No. 1 Knife” patent invalidation and litigation case, and the patent invalidation and litigation case between Feitian Trust and Israel's Aladdin. These typical cases have had a certain social impact.

With the company's further involvement in intellectual property operations and commercialization, Mr. Zhang has conducted extensive research on technology transfer, technology valuation in project investment, and has participated in numerous technology innovation project research, analysis, and investment review and decision-making. He has a unique and profound insight into the valuation of projects in energy conservation, environmental protection, new energy, new materials, and advanced manufacturing industries. He is a versatile expert in the intellectual property field.
