Trenner Law Firm was built on a simple but powerful premise: intellectual property legal services should be accessible, transparent, and centered entirely on the client’s success. After years of working in traditional law firms, Mark realized that the standard billable-hour model often created a barrier between inventors and their legal counsel. He established Trenner Law to break that cycle, offering a modern, online-based practice that provides high-level expertise without the unpredictability of traditional billing.

What sets Mark Trenner apart is a deep-rooted technical foundation that allows him to speak the same language as his clients. With three engineering degrees—including a B.S. in Electrical Engineering and an M.S. in Environmental Engineering—Mark brings a unique perspective to every patent application. His background spans a vast array of technologies, from software and electronics to mechanical systems and renewable energy. This technical fluency ensures that the "nuance" of an invention is never lost in translation when communicating with the U.S. Patent and Trademark Office.

At Trenner Law Firm, the focus is on strategy rather than just paperwork. Whether you are an individual inventor, a scaling startup, or an established small business, you receive personalized attention directly from Mark. The firm’s hallmark is its flat-fee, project-based pricing. By eliminating the "ticking clock" of hourly billing, Mark encourages open communication, ensuring that clients feel comfortable asking questions and exploring strategies without fear of receiving an unexpected invoice.

Beyond patent prosecution, the firm provides a holistic approach to brand and asset protection. This includes:

• Provisional, non-provisional, and design patent filings;
• Federal trademark registration and brand protection strategy;
• Helping clients prioritize filings to maximize their budget and long-term business value.

With over 25 years of experience, Mark Trenner has helped hundreds of clients secure their ideas and scale their businesses. Based in Colorado but serving clients across the U.S. and internationally, Trenner Law Firm remains a dedicated partner for those who want to turn their innovations into protected, valuable assets.
