Patent Search CN/US

Overview

Plan and execute a preliminary patent search for CN/US, then summarize novelty risks and gaps with a traceable search log.

Workflow

1) Scope the invention

• Extract the core technical problem, steps, and outputs.
• List essential features vs. optional features.
• Capture synonyms in EN + CN (translate key terms both ways).
• Define the jurisdiction scope (CN, US, and optionally WIPO/EPO) and time range.

2) Build search queries

• Start with 3-5 keyword clusters (problem, method, system, output, domain).
• Add technical terms, abbreviations, and synonyms; include Chinese equivalents when searching CN.
• If available, map to IPC/CPC classes and include them as filters.
• Add assignee/inventor filters only when narrowing is needed.
