Elizabeth Isaac helps businesses, innovators, entrepreneurs, and artists assess and protect their inventions, brands, designs, and creative works to leverage their intellectual property portfolios and enhance their business options. She counsels clients regarding a breadth of intellectual property with an emphasis on creatively and strategically identifying wholistic and dynamic ways to improve the value of various creative and technological assets.

Elizabeth’s practice includes all areas of intellectual property, patent preparation and prosecution, due diligence, trademarks, copyrights, entertainment law, and Internet law as well as licensing, transactional, and litigation matters. Her patent work includes patent drafting and prosecution for clients in a variety of industries such as medical devices, industrial products and systems, food and beverage industry products and systems, consumer products and methods of manufacturing, product packaging, cable analytics, and energy. In addition to patent prosecution, Elizabeth analyses the proprietary technology of target companies and conducts freedom to operate and state of the art analysis.

Her trademark work encompasses brand portfolio management, clearance, prosecution, issuing and responding to cease and desist letters, and the negotiation of trademark settlement agreements. Her design and copyright work includes creative works portfolio management, design patent and copyright preparation and prosecution, as well as validity and ownership analysis.

In addition to helping diversify the intellectual property portfolios of clients, Elizabeth assists businesses and individuals in navigating and mitigating the risks associated with the intellectual property rights of others. She negotiates deals between rights holders and third parties seeking to obtain permission to use protected inventions, brands, designs, music, and film.

Her transactional practice extends to drafting licensing, services, subscription, terms of use, development, and publishing agreements—touching all forms of intellectual property.

Elizabeth was recently tapped to serve on the 2018 Board of Directors for deadCenter Film. The deadCenter Film Festival is located in the exact center of the United States and showcases independent local filmmakers as well as international luminaries. In 2017, she was named one of The Journal Record’s “Achievers Under 40.”

Prior to working at Dunlap Codding, Elizabeth clerked for Justice Bill Meier at the Second Court of Appeals of Texas in Fort Worth and served as a research assistant for Dean Laurie Jones at the Oklahoma City University School of Law. She served as a Youth Service Corps Coordinator at the Ghost Ranch Conference Center in Abiquiu, New Mexico, and as a Felony Prosecutor Assistant and Public Relations Intern at the District Attorney’s Office in Palestine, Texas. Elizabeth received her B.A. degree, magna cum laude, from Austin College in Sherman, Texas in Communication with a Media Focus.
