David May represents clients in all aspects of intellectual property law. He routinely assists clients in developing global IP portfolios with a focus on maximizing the commercial value of their IP.

What do you focus on?

Brands and Creations

I provide my clients with comprehensive brand management advice. This involves assisting clients in selecting, clearing and adopting new trademarks, registering marks with trademark offices worldwide and enforcing and defending their rights. I focus in identifying and implementing creative solutions to overcome complex issues. These include advising on “non-routine” trademark issues, such as those involving issues of false advertising, unfair competition, design and trade dress protection.


Protection of inventions and enforcement of patent rights is a fascinating aspect of my work. I enjoy analyzing prior art and advising on issues of patentability and in prosecuting patent applications involving various technologies. Over the years, some of these have included sports equipment, medical devices and methods, electronics, computer software, garments and business methods.


In the area of copyright law, I help with issues of authorship, copyrightability and registration of creative works. I represent clients in registering creative works with the U.S. Copyright Office.

Intellectual Property Enforcement

I assist in intellectual property enforcement proceedings and have successfully concluded numerous proceedings before the U.S. federal courts, the U.S. Trademark Trial and Appeal Board and before the World Intellectual Property Organization.

What do you see on the horizon?

Intellectual property owners are constantly having to properly identify and protect their assets against misappropriation and counterfeiting. In today’s global economy it will be more important than ever for companies to understand the nuances and differences in laws from one jurisdiction to another to suitably develop and commercialize their portfolios.
