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.
3) Run searches in public databases
  • Use at least one CN database and one US database.
  • Include Google Patents as a cross-jurisdiction sweep.
  • Optionally use WIPO PATENTSCOPE or Espacenet for broader coverage.
  • Reference site list: references/patent-search-sites.md.
4) Triage and record results
  • Scan titles/abstracts; keep candidates that overlap with the essential features.
  • Open claims for the top hits; record claim elements that match or differ.
  • Keep a log with: database, query, filters, date, and top hits.
5) Assess novelty risk
  • For each candidate, mark: full match / partial match / non-match.
  • Identify distinguishing features (potential novelty points).
  • Call out risky overlaps and missing evidence (gaps).
6) Produce a preliminary novelty search report
  • Include: scope, queries, databases, key hits, and novelty assessment.
  • State limitations (public sources only, no paid databases, time constraints).

Output checklist

  • Search scope and assumptions
  • Keyword clusters (EN/CN)
  • Databases used and date
  • Query strings and filters
  • Top results summary (title, year, link)
  • Novelty assessment and risk notes
