Patent Validity / Invalidity Searches

Invalidity Search or Validity Search is the most exhaustive search conducted after the grant of a patent. A search is conducted to identify patent or non patent literature filed or published before the earliest priority date of the subject patent. The search serves as a basis for a legal opinion against infringement or as due diligence prior to licensing, buying, or selling of a patent.

Since inception, we have handled more than 400 patent validity or invalidity searches. Our practical knowledge and over time experience of working for some of the top law firms and corporations in the world has helped us evolve various strategies to perform comprehensive validity/invalidity search and analysis.
