Professional Background

Nearly a decade in the patent profession, holding the Chinese patent attorney qualification with five years of practice and focused on the full patent lifecycle in mechanical engineering. She has served a number of well-known domestic manufacturers in automation, intelligent equipment and precision machinery, and has extended into medical devices — surgical instruments, rehabilitation aids and in-vitro diagnostic equipment. In 2024 she founded Hefei Zhihai Yida Patent Agency (General Partnership), where she is responsible for quality control across all patent work and for building the team. Under her leadership the firm has been listed in several local “targeted service support” programmes and has obtained pre-examination qualification from major Chinese IP protection centres — so client cases can use the fast-track pre-examination channel and reach grant far sooner.

Representative Cases

· During her practice at Zhihai Yida, the grant rate for concluded invention-patent cases is 77.27% (including voluntary withdrawals; figures as of 21 August 2026; excluding voluntary withdrawals the rate approaches 100%)
· Led patent portfolio planning for several equipment-manufacturing and electronics companies
· Handled a number of patent reexamination and invalidation cases, keeping clients’ core patent rights stable
