Patterson Belknap’s attorneys are deeply involved in the complex issues facing the biotechnology industry. Our practice includes highly experienced trial attorneys with extensive technical knowledge in the field. A number of our attorneys have Ph.D.s in molecular and cell biology, immunology, and biochemistry.
We represent biotechnology companies in a broad range of litigation matters, including patent infringement cases, patent licensing and other contractual disputes. We represent both patent holders and accused infringers in cases involving a wide variety of subject matters, such as monoclonal antibodies and fragments, expression of recombinant proteins, DNA and RNA probes, analysis of polymerase chain reaction (PCR) products and genetic transformation techniques.
Patterson Belknap litigators try cases in federal court in every judicial Circuit and regularly represent clients in alternative dispute resolution proceedings. We have also assisted in foreign counterpart litigations by coordinating positions, preparing witnesses, and assisting foreign counsel at trials.
The technical knowledge of our attorneys enables the Firm to represent clients not only in patent infringement litigation but also in AIA trial proceedings and complex reexamination proceedings before the U.S. Patent & Trademark Office. In addition, we negotiate patent licenses, counsel on new product launches and provide opinions concerning validity and infringement of biotech patents.
