On Friday June 13, 2025, Wanhuida Intellectual Property and PatSnap jointly host a thematic salon focusing on the hot-button issues pertaining to patent assertion in the renewable energy and chemical industry at Wanhuida’s Beijing premises at Yiyuan Office Building, Friendship Hotel.

The three-hour salon has over 100 participants tuning in either visually or in person.

The event is kicked off with a very informative presentation made by Wanhuida Partner Tang Tiejun. Tiejun shares insights on “Patent Drafting Strategy: From the Perspective of Patent Invalidity Actions and Infringement Suits”. By delving into the fundamentals required in maintaining the validity of a patent, she offers, from the case law perspective, key takeaways on how to preemptively install in the drafting process guardrails to fend off possible invalidity actions and infringement suits.
