Patent Validity and Invalidity Search

Prior-art research to inform patent validity, invalidity and dispute-related questions.

A practical, informed approach

Validity and invalidity searches review patent and non-patent literature against a defined patent, claim set or technical issue. Results are organised to help the client understand potentially relevant disclosures and the limits of the search.

Who this service is for

Inventors, technology businesses, R&D-led organisations, universities and companies assessing or protecting technical innovations.

Typical workflow

  1. Define the patent and question
  2. agree search scope and date limits
  3. search relevant sources
  4. review key references
  5. provide a structured report.

Key considerations

Search results depend on scope, sources and available records; they do not determine a court or Patent Office outcome.
