Validity Search

Product characteristics

We search international patent databases and non-patent literature. The scope of the search will be references that either alone or combined can challenge the validity of the patent. Upon conclusion of the search a report will be made which will include:

  • Specification of the aim of the search.
  • Description of the scope of the search.
  • Overview of references found, divided into categories depending on their relevance.
  • Detailed specification of the relevant parts of the references and analysis of why the examiner considered it relevant.
  • Search strategy and databases used for the search.

A claim chart that shows the correspondence between the prior art and the claimed feature can be added.

Specifications needed

We need the number of the patent or the patent application. We also need to know if there should be any claims or claim features that are more important than others.
