Mr. Larson is one of the most down-to-earth people you could ever meet. It’s not every time that you meet someone, especially certain professionals, and feel an instant liking for them. I never felt like he was just trying to push through my application process like I was a part of an assembly line of other clients. I could tell that he was truly interested in the product that I needed IP protection for. The advice that he gave was sound and solid. He was always available if I needed to call for a follow up question, either by phone or email. I highly recommend anyone needing intellectual property protection for their idea or product consider using Larson & Larson. They are true professionals, Bill Larson is a great guy and attorney. - James Jones Jr.

There is not enough room to give kudos to Larson & Larson. Really Bill, Mickey EVERYONE at the firm is extraordinary! I have used them for several patents and trademarks. I will never need nor use a different patent attorney. Once I get moving on the ones in the que, I am submitting 7 more with them. If you are looking to file your first patent or your 10th, Larson & Larson will give you all the expertise you will need to be a complete success. Oh, they do not just collect a check and vanish. They keep in constant communication all the way through. In fact Frank just emailed me this morning that they got government approval for "The Jar Dragon". I am soooo excited!
God bless you Bill Larson and the entire family at Larson & Larson because that is what they have become. FAMILY!

After 20 years from the original registration of our company trademark, Larson & Larson was proactive in letting us know of the need to renew (which we certainly didnt have on sight), and expeditiously Mickey and Bill prepared the necessary paperwork to keep the protection for another term. Hopefully in 20 years you can remind me again!
