Joe has secured two patents for me and always stays on top of the details. He's a very honest and moral man and treated me very well. If you're looking for a patent attorney, he's a very good choice. He will listen to your idea give an honest opinion on your chances.

Many thanks to Calhoun Law Firm. After obtaining a patent for my predecessor, Joe Calhoun organized and formed our holding company for commercializing the patented technology. He ably assisted us in many development activities, which eventually resulted in a purchase of our technology. If you are considering filing or commercializing a patent I strongly suggest you contact Calhoun Law Firm! Charles Worden Jr.

Calhoun Law Firm provided excellent legal representation in defending me in a breach of contract lawsuit. By the time the case settled, the opponent ended up paying me money rather than me paying them!

Joseph Calhoun did a wonderful job for my husband and me. We needed help with a business matter, and I felt very confident after speaking with him that I called the right law firm. I'm extremely happy with the work Mr Calhoun did on our behalf. He is very professional, and I highly recommend him! If I need legal help in the future, I will not hesitate to call him.
