Turn Your Innovative Idea Into a Valuable Business Asset
When you work with Mark Trenner, you're not getting a document filer — you're getting a translator between the worlds of engineering and law. Flat-fee pricing. No billable hour anxiety. No surprises.
You've Built Something Remarkable.
Now You Need to Protect It.
If any of these sound like you, you're in the right place.
You have an invention that could change your industry — but you're not sure if it's patentable or where to even start.
You're worried about legal costs spiralling out of control. You've heard the horror stories about surprise attorney bills.
You know you need to act fast — a trade show, product launch, or investor meeting is coming up — but you don't know the timeline.
You've tried to navigate the USPTO yourself, or hired someone who didn't explain what was happening, and you ended up confused or denied.
You're building a brand and you need to know that nobody else can use your name, logo, or tagline in your market.
You've talked to attorneys who clearly didn't understand the technical details of what you built — and you spent half the call explaining basic engineering.
You're not alone — and you don't need to figure this out by yourself. Nobody understands your invention better than you do. My job is to listen first, then apply 20+ years of engineering and legal expertise to build your moat.

When you work with me, you aren't just getting a legal technician. Since founding Trenner Law Firm in 2004, my goal has been to put the inventor's needs first — and to speak your language.
With a background in Electrical and Environmental Engineering and over two decades of hands-on IP practice — including serving as in-house senior patent counsel at the National Renewable Energy Laboratory (NREL) — I grasp the intricacies of complex hardware, software, and mechanical systems without needing a long "learning curve" at your expense.
As a business owner myself, I know what it feels like to need professional help and worry about what it's going to cost. That's why I work on flat fees, explain everything in plain English, and make myself available when it matters — including outside regular business hours.

What Inventors & Entrepreneurs Say
Real reviews from real clients on Google.
"I found Mark Trenner of Trenner Law Firm, LLC to be the most confident and knowledgeable patent attorney I've had the pleasure to work with. This was my 4th patent attorney/agent and I'd definitely hire Mark above all others — and that's from a Physics Nobel Prize Candidate and serial inventor telling you his work is top notch. Stop looking as you've found the best. I'm impressed and very pleased!"
"I had a fantastic experience working with Mark from Trenner Law Firm. He was professional, respectful, and extremely knowledgeable. Mark took the time to explain everything clearly and made the entire process smooth and stress-free. I truly felt like I was in good hands."
"As a designer, finding a good patent attorney is a challenge. Trenner Law exceeded my expectations and does a great job at explaining in layman's terms how best to develop a robust and defendable patent at a reasonable price."
"Mark did a great job assisting me with my trademark. At first, after applying on my own, my trademark was denied — but after an appeal through Mark they accepted it. If I were to do it all over again I would go through Mark at Trenner Law Firm."
