Methodology

Patent research is an art as well as a science and requires a constant stream of judgment calls by the researcher. Epsilon’s staff is rigorously trained and can be trusted to make competent decisions at critical junctures in the search process. Our researchers routinely deploy an effective combination of manual (using both USPC and CPC schedules), keyword, and assignee searching. We are well-versed in using Boolean logic to locate and extract the most pertinent references and have vast experience with IEEE, Google Scholar, PubMed, and dozens of other on-line literature databases. In addition to relying on the USPTO’s EAST system, we have various proprietary patent research tools at our disposal, including LexisNexis TotalPatent One.

Confidentiality and Security Measures

Epsilon takes confidentiality seriously, and the security of your client’s intellectual property is of utmost importance to us. We never off-shore our research.
