Our Intellectual Property attorneys have worked with international businesses, public interest organizations, sole proprietors, public figures, authors, and other clients to protect their intellectual property. We can help protect yours, too.

Overview

The firm handles a variety of intellectual property matters, from routine matters like registering trademarks and copyrights, to complex litigation involving patent validity and infringement, inequitable conduct, copyright, trademark, and trade dress infringement, and appropriation of trade secrets.

We are an experienced extension of your team

Our team includes lawyers who are nationally ranked in The Best Lawyers in America and other national listings, and attorneys who have served in professional organizations focusing on intellectual property issues.

We always seek to resolve disputes for our clients in the most cost-effective manner possible, but sometimes, litigation is unavoidable. In such cases, our team will complement the skills of your in-house IP team by bringing our extensive courtroom experience to the table. We distill even the most complicated intellectual property matters to simple concepts, easily understood by both judges and juries.
