Validity / Invalidity Search Services

Ensuring Patent Strength. Enabling Informed IP Decisions.

Patentability — Final Code

What is a Validity / Invalidity Search?

A Patent Validity Search is performed to check whether a granted patent is strong, enforceable, and free from earlier undisclosed prior art.

A Patent Invalidity Search is conducted to identify prior art that can be used to oppose or revoke an existing patent by challenging its novelty, inventive step, or industrial applicability.

This search examines worldwide:

  • Granted patents
  • Published patent applications
  • Technical research papers
  • Journals and conferences
  • Books and standards
  • Market products and manuals
  • Non-patent literature (NPL)

For patent attorneys, patent lawyers, consultants, and patent companies in India, this search is a critical tool during litigation, licensing, and competitive strategy.
