Trenner Law Firm: Intellectual Property Counsel for Tennessee Innovators
Knoxville, Tennessee, is a city with a strong foundation in creativity and innovation. Its dynamic community of entrepreneurs, inventors, and forward-thinkers makes it a hub for new ideas. East Tennessee has built a strong reputation for engineering, research, manufacturing, healthcare innovation, energy technologies, and entrepreneurial growth. From emerging startups and family-owned businesses to university-driven research and technical innovation, Knoxville and the surrounding region continue to produce companies solving meaningful technical and commercial challenges.
As a patent attorney licensed in Tennessee for the past eight years, I work with inventors, founders, engineers, entrepreneurs, and businesses throughout Knoxville and East Tennessee to protect inventions, brands, and intellectual property through strategic patent and trademark counsel.

My connection to East Tennessee extends well beyond my legal practice. My family has deep ties to the region through the University of Tennessee community, where both my son and daughter currently attend school. That connection has given our family the opportunity to spend significant time in downtown Knoxville, attending Tennessee Volunteers football games, supporting university athletics, and experiencing the entrepreneurial energy that makes this region unique.
Outside of my practice, my family and I have also spent countless weekends enjoying East Tennessee’s outdoor culture, camping, hiking, and fishing throughout the mountains, lakes, and public lands that define this part of the state.
Those personal connections, combined with my engineering background and patent practice, give me a genuine appreciation for the people, businesses, and innovation culture that drive Knoxville and East Tennessee.
