Don Tiller

Don Tiller became fascinated with entrepreneurship based on technology and intellectual property. This led to law school at Texas Wesleyan University School of Law (now Texas A&M University School of Law) from 2004 to 2008. He has been practicing law since 2008 and is a registered patent attorney.

Don's early legal experience was heavily weighted toward litigation involving intellectual property or technology and has since evolved to include foundational transactional matters and patent and trademark prosecution.

Legal issues with respect to technology and intellectual property often center on the value of a particular piece of technology or intellectual property. After repeatedly digging into entrepreneurial economics, he decided to formalize his study of IP and technology valuation. In 2018, he completed an MBA with a primary interest in entrepreneurial finance within mature, emerging, and startup businesses.

Don Tiller brings all this experience to the table since founding D. Tiller Law PLLC in 2014. In one respect, he is a patent lawyer who practices intellectual property law. But his intellectual curiosity and holistic approach to connecting these varied interests provide clients with a much wider range of service. Tiller is a scientist and an attorney who works with entrepreneurial clients to foster an idea to grow it into a game-changing business venture.
