Trevor Cloak wrote an article on discrimination on the basis of sexual orientation or gender alone being unlawful.

From the food and beverage industry to the software and technology sector, Trevor acts as an advocate for clients operating in a variety of disciplines with respect to their intellectual property transactional, prosecution, enforcement, and litigation needs. Whether he is defending a food and beverage client from a threatened temporary restraining order concerning the use of a trademark or negotiating a complex master software subscription services agreement on behalf of a multibillion-dollar software client, Trevor fluidly ties together his transactional and litigation knowledge and experience to zealously advocate for his clients. Accordingly, he is able to find unique and possibly overlooked transactional-based arguments to raise in connection with litigations and to analyze intellectual property-related agreements with a litigant’s eye, both to help clients better negotiate their positions and to avoid potential pitfalls in the future.

Trevor has experience representing clients with respect to all aspects of intellectual property due diligence, in drafting and negotiating technology, software, and software-as-a-service agreements, Hosted Services Agreements, Master Software Development Agreements, Hosted Reseller Agreements, and Mobile Application End User License Agreements. Trevor also counsels clients with respect to trademark, copyright, and patent licenses, joint development agreements, non-disclosure and confidentiality agreements, employee invention assignments and confidentiality agreements, website terms and conditions, privacy policies, coexistence agreements, and settlement agreements. He is also knowledgeable regarding data security and data breach issues, trade secret law, domain name disputes, and rights of publicity and assists clients with trademark and copyright prosecution, enforcement, and litigation.

Trevor taught Introduction to Technology Law and Ethics as an adjunct professor at the University of Pennsylvania Law School, Masters in Law program.

Trevor earned his bachelor's degree from Middlebury College where he graduated summa cum laude in environmental studies and chemistry. Trevor earned his law degree from Vanderbilt University Law School where he was an Order of the Coif and a member of the Vanderbilt Law Review. During law school, he interned at the U.S. Attorney's Office for the Eastern District of Pennsylvania. Following law school, he clerked for the U.S. Court of Appeals for the District of Columbia.
