Validity search

Sometimes a supplementary search related to a patent that has already been granted is required. The aim can be to determine the strength of the protection of a patent to be sold or licensed, or to search for novelty bars to revoke the competitor’s patent.

Please note that neither the grounds for granting a patent nor the term of a patent are questioned in this search. The search is not carried out on patents granted by the Finnish Patent and Registration Office (PRH).

Outcome of the search

A validity search focuses on determining the search strategy and the databases used, and in addition it focuses on examining patent databases and also international non-patent literature published before the filing date of the patent in question. Such publications are also searched for that may be significant for the assessment of novelty or inventiveness of the patented invention.

The search report includes information on cited documents, used databases, patent classes and key words. The cited documents are classified in three categories:

  1. Significant when considering the novelty and inventiveness of the invention
  2. General state of the art
  3. Cited for other reasons
