Mark Leonardo’s intellectual property practice is centered on his client’s technology, products and brands in a wide range of industries that involve transactions, enforcement, technology transfer and counseling matters. Mark advises clients with respect to business and transactional aspects of intellectual property, including commercial exploitation and management of patent and trademark portfolios, patent and trademark procurement and opinion counseling on complex legal and technical issues. He assists clients in developing comprehensive and strategic patent and trademark portfolios that maximize a company’s competitive advantage, negotiating technology development, licensing and technology transfer agreements as well as litigation and pre-litigation protective measures.

Mark works with clients to acquire, develop and exploit intellectual property assets and has specific experience in developing arrangements where patents and brands are of ultimate value. He counsels clients regarding the development and enforcement of patent and trademark portfolios, including technology, consumer products, sporting, luxury goods, hotel and leisure, and apparel companies.

Mark is particularly active in counseling clients in connection with the acquisition and protection of intellectual property rights in corporate transactions, including strategies for protecting their organization’s intellectual property, evaluating the intellectual property of their prospective business partners, assessing merger candidates, corporate due diligence and intellectual property investigations in conjunction with acquisitions, divestitures and mergers, secured transactions, venture financing and public offerings.
