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 agent at a leading Chinese IP firm.One of my strengths is patent validity matters, on both the offensive or defensive side. I have kept a general success rate of above 70% in my career so far. My 12 years of experience as a patent examiner and an agent allow me to have a deep understanding about various factors in patent validity. I can advise clients on not only the general strategy but also the detailed wording to increase the chances of obtaining 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.
