About

Provided by McCarter & English, LLP

Working dynamically across the core intellectual property law disciplines of patents, IP litigation, post-grant proceedings, trademarks, and copyrights, our Intellectual Property practice takes an integrated approach to delivering solutions that strengthen, defend, and enforce our clients’ innovations, brands, and original works. Our IP team of more than 100 lawyers and patent professionals combines technical and scientific acumen with legal skill and experience to collaboratively advance the assets and aspirations of today’s companies.

We have more than 65 patent lawyers, technical specialists, and patent agents spanning our nine offices who have industry training and/or advanced degrees in life sciences, technology, and engineering, as well as experience as former patent office examiners well versed in the intricacies of the US Patent Office.

An intelligent approach to the pursuit of our clients’ business objectives is a hallmark of our IP Litigation practice. We start with an assessment of our client’s goals and design the strategy that will best fit their situation. Our litigators have decades of experience litigating cases for some of the largest manufacturers and pharmaceutical companies in the world, and in some of the most complex cases in courts all over the country. Whether it is bet-the-company litigation or finding the most cost-effective way to respond to a nuisance action, McCarter’s litigation professionals bring the same experience to bear for each case.
