Leydig’s biotechnology attorneys and patent agents keep informed of the field’s advancements in medicine, agriculture, horticulture, veterinary products, food processing, and green technology. We have particular expertise with the patenting of nucleic acid sequences, proteins, antibodies, cell lines, vectors, and vaccines, as well as their applications, ranging from diagnostic assays to treatment methods and industrial processes.

Our services in the biotechnology space include providing legal opinions concerning freedom-to-operate (infringement clearance), patent validity, and patent enforceability; handling intellectual property due diligence investigations, such as those associated with technology and company acquisitions, financing, and the like; consulting on license agreements; preparing patent landscape reports; structuring and managing patent portfolios; and drafting and prosecuting patent applications.

We also routinely represent clients in adversarial proceedings, including litigation in the U.S. courts, and in inter partes reviews, reissues, post-grant reviews, and derivation proceedings before the U.S. Patent and Trademark Office. In addition, we represent clients in enforcement and invalidity proceedings before non-U.S. tribunals in cooperation with our numerous international colleagues.
