Services we offer

Striving for excellence in all we do

Patent Filing

We draft and prosecute new patent applications for pharmaceutical and chemical companies from around the world. We understand the pharmaceutical development process, and specialize in protecting new molecules, as well as old molecules whose compound patent has expired. Our patent portfolios have withstood large-scale assaults from generic competitors, and significantly lengthened the lives of our clients' most valuable assets.


Clark began his career as a commercial litigator and well understands the nuances of the commercial litigation process. Clark acts as first chair for the firm's clients on smaller litigation matters and, depending on the complexity of the matter, plays supporting roles in cases involving patents, antitrust, false advertising, and breach of contract.

FDA Advice

We advise clients on FDA exclusivity periods and approval requirements, including 505(b) and (j) approval pathways, the latest biologics and orphan drug developments, and Orange Book and generic substitution issues. We understand the regulatory approval requirements for pharmaceutical and biological products, and work closely with our clients to develop patent strategies that withstand challenge and ensure the longevity of our clients' investments.

Clark understands the drug development process and has done a great job protecting our new drug products.
