We understand the importance of thorough, in-depth patent research. Our veteran search professionals dig deep, drawing on their subject matter expertise and utilizing the best strategies and technologies to efficiently uncover the information you need.

With every search project, you receive a report that maps the results to your search goals. PDF copies of the references cited in most searches are accessible directly through our Search Report System. You’ll also receive a search history detailing the databases, classes and keywords used in the search. Standard search coverage includes English-based patent and non-patent literature, as well as English abstracts of many foreign language patents and published applications. Foreign-language specialists may be added to a project team to perform research on the full text of non-English documents. Each research project is facilitated by a project manager who is experienced in their technical field, and who acts as a valuable liaison – before, during and after each project.

We can customize specific
