With over ten years of experience in patent agency, I specialize in patent invalidation requests, administrative litigation, third-party observations, and reexamination proceedings. I possess strong technical comprehension skills, enabling me to conduct evidence retrieval and collection for invalidation cases and third-party submissions, draft petitions and complaints, prepare statements of opinion during invalidation procedures, and participate in oral hearings. My expertise covers the fields of chemical engineering, chemistry, and mechanical technologies, including reexamination, invalidation, patent administrative litigation, and patent infringement litigation.
