As a managing associate in our Intellectual Property team in Shanghai, I am a qualified PRC patent attorney with solid and rounded experience in handling patent matters.

I am particularly experienced in advising clients from technology-driven industries including telecommunications, mechanics and chemistry on patent searches, drafting, filing and prosecution, analysis of issues including patentability, validity, infringement and freedom-to‐operate, as well as transactional work and patent litigations in PRC. I also advise on the protection and enforcement of other IP rights and unfair competition.

Before joining the team at Bird & Bird, I worked as a Patent Examiner at SIPO and practised as a patent attorney at a leading Chinese IP firm.

One of my strengths is the patent validity matters, at both the offensive or defensive side. I have kept a general success rate of above 70% in my career so far. My twelve years of experience as a patent examiner and an attorney allows me to have a deep understanding about various factors in patent validity. I can advise clients on not only on the general strategy but also the detailed wording to increase the chance to obtain a decision in favour of my clients. Challenging the validity of a patent is almost a necessary process of an infringement case in China. I also advise clients about the consistency between the validity and infringement arguments.

I am fluent in both Mandarin and English.

  • I assisted a Canadian materials company, Neo to achieve favourable patent invalidation decisions announcing all the claims of three patents owned by its competitors are invalid. These decisions leads to two civil actions against Neo were dismissed.
  • I assisted a Dutch packaging company, Ardgah group to enforce its invention patent in China with a final decision containing injunction and damages. In the process of the infringement case, I successfully defended two rounds of invalidation actions filed by the defendants and maintain all the claims of the patent valid.

Beijing Higher Court accepted our arguments about the scope of disclosure of the prior art documents and whether some features of a design patent is functional.
