Patent Prosecution

We have extensive experience in all areas of patent prosecution, handling not only patentability assessments, inventorship determinations, application preparation, and worldwide filing and initial prosecution strategy development, but also appeals, reexaminations, reissues, and interferences. We also work with and direct our foreign associates in local prosecution, oppositions, appeals, and cancellation proceedings in order to maintain a coherent and consistent strategy throughout the world. Our comprehensive experience in the law of intellectual property, in concert with our superior knowledge of technical subject matter, enables our attorneys to develop prosecution strategies as unique as the invention itself. Our ability to maximize the return on client investment results from formidable legal skill and experience; thorough preparation; precise accuracy and an uncommon level of imagination, working in complete harmony with the creative thinking of our clients.
