Patent Searching

Expert Research Teams

Our research teams are custom-assembled, based on the technology of the requested research. Each team in led by a project manager, who is a patent attorney* with the requisite subject matter expertise. The project manager acts as a valuable liaison before, during, and after each search project allowing you to get the results you need.

Our veteran search professionals include patent attorneys*, patent agents, and former patent examiners, all with extensive technical knowledge. They utilize sophisticated search strategies for each project, accounting for individual features and combinations using multiple classifications, subclasses, keywords, and synonyms. In addition, they are all well-versed in the concepts of anticipation and obviousness, which gives our researchers further insight when reviewing identified documents.
