John J. O'Malley



Clients prize John’s wealth of creative ideas for growing and protecting their businesses. Naturally outgoing, he has developed an extensive network of contacts that benefit clients as he advances their interests. John works closely with clients of all sizes and types to develop strategies for building brands and developing and protecting U.S. and international trademark portfolios.

A significant part of his practice involves counseling startups and emerging companies on taking their business to the next level.

John’s trademark work includes providing clearance opinions as well as preparing and prosecuting trademark and copyright applications. He also routinely conducts IP audits and IP due diligence for banks, IP investment companies, venture capital firms and private equity investors. His work further extends to negotiating and drafting intellectual property agreements including licenses, confidentiality assignments, joint development, software development, and website development agreements. John regularly handles domain name disputes and acquisitions and counsels clients on IT, internet, website and e-commerce transactions.

Litigation can be an important and necessary step in protecting intellectual property rights and John has litigated and enforced rights involving trademarks, domain names, patents, copyrights, unfair competition, false advertising and the internet.

John is also an adjunct professor at Villanova University Charles Widger School of Law where he teaches IP Licensing and Strategy.
