Technical Areas

Partnering with Cardinal provides you access to an efficient and talented team with the expertise to manage a wide variety of research projects. In no small part due to this talented team and our broad range of expertise, the USPTO selected Cardinal to perform Patent Cooperation Treaty (PCT) searchers and prepare written opinions across all subject categories.

Our Highly-qualified professionals utilize sophisticated search strategies for each project, accounting for individual features and combinations using multiple classifications, subclasses, keywords and synonyms.

Our research professionals include patent attorneys*, patent agents, and former patent examiners, all with strong technical knowledge. They are also well-versed in the concepts of anticipation and obviousness which gives them further insight when reviewing identified documents. Each research project is facilitated by a patent attorney* with the requisite subject matter expertise who acts as project manager before, during and after each project.

It is no wonder that time and again, for searches in any technology areas, clients such as the USPTO choose Cardinal.

Biotechnology

For projects requiring nucleic acid and protein sequence searching, Cardinal searches GenomeQuest and STN databases in addition to our standard review of U.S. and foreign patent and non-patent literature databases. Our non-patent literature research covers PubMed and Medline, and ScienceDirect, as well as free databases such as Google, Google Scholar, and freepatents online. We efficiently search nucleotide and amino acid sequences using different algorithms including BLAST, fragment and motif searching, and we can limit the results to a particular percent identity of the target or query sequence. Electronic filtering of result sets includes, but is not limited to, priority dates, inventor names, keywords and organisms.
