Career Experience

Professional Background

February 2012 - February 2017: Served as an invention patent examiner in the Optoelectronics Department of the CNIPA Patent Office. She handled the full substantive examination process for communication-field invention patents, used domestic and international databases for prior-art search, drafted office actions, and communicated with patent agents and applicants. During this period, she closed more than 500 patent examination cases with strong quality and efficiency.
Quality control and research: Served as a member of a departmental examination quality assurance group, taking part in regular office-action quality review and difficult-case panel discussions. She was also selected for communication soft-science research and measurement-testing specialty research groups, participating in patent-law and field-specific patent research projects.

Drawing on years of patent examination experience, she contributes to agency quality control, difficult-case analysis, service-standard optimization, and risk-control system building for clients.

Examiner-Grade Comparison

Why this background fits communication and electrical FTO.

FTO work in communication and electrical technologies often requires careful interpretation of claim language, functional module mapping, signal-flow analysis, control-logic comparison, system architecture review, and equivalent-infringement risk assessment. Liu's invention examination training gives her a structured way to move from technical decomposition to search, from distinguishing features to examination logic, and from claim reading to practical risk conclusions.

Quality and Service

Embedding patent quality discipline into client service.

In market-oriented IP service, Liu reviews matters through document quality, claim stability, grant strategy, potential infringement risk, and future enforceability. This helps companies build a more reliable decision framework across patent filing, reexamination, FTO, overseas portfolio planning, and difficult patent cases.
