Intellectual Property Law:

Intellectual property is a significant asset for companies in today’s competitive landscape. Protecting that asset is critical. Intellectual property is more than patents and trademarks — it is the people, practices and big ideas that keep a business running. No matter the industry, organizations need legal counsel that can identify, protect and enforce their ongoing IP rights and that can secure their freedom to operate in the marketplace.

Leon has twenty years of experience practicing IP law.  We focus on providing comprehensive legal strategies to support clients’ needs and goals.
