Excellent patent attorney
Mr Claiborne was an incredible asset in every step of the patent process. His deep understanding of both the legal and technical sides of the patent application gave me a ton of confidence. Plus, his experience with the patent processing and excellent communication made the application process much smoother than I anticipated. He took the time to deeply understand the subject matter - those details really mattered and made for a much more effective final patent application. Overall, his dedication, expertise, and thoroughness in handling a patent application were exceptional. I highly recommend him to anyone seeking a knowledgeable and detail-oriented patent lawyer.

Success with 2 trademarks - Highly recommend!
I enlisted Anthony Claiborne’s trademark services. I was able to secure 2 trademarks with his professional help. He was timely, updated me through the process and accomplished the goal all while being professional and a joy to work with. His price was very fair as well! I will be enlisting him for his services again as my company grows and I need further trademark help. I highly recommend him!!!

Quick, Accurate, Complete
Anthony took the time to completely understand the scope and nuances of my invention. He used his engineering and understanding of patent law to guide my application, adding value but not overstepping. I feel fortunate to have met him, and have him on my team.

Rock Star IP attorney
Anthony Claiborne goes above and beyond the call of duty. He not only provides prudent and practical advice, but a calm and compassion that pulled me down from the ceiling during a very angst ridden IP contract negotiation. He is also a seasoned pro who knows how to tread softly on the slippery slope so that your rights are protected in a non-adversarial fashion. He is also easily accessible, and returned my calls and emails promptly. Attorney Claiborne is a rare gem who I would highly recommend to friends and family for all their patent, trademark, and intellectual property needs. Thank you again, Anthony for being my staunch advocate.

Pleasure working with Anthony
It was great to work with Anthony over the past few months. I had conducted consultations with various trademark lawyers. From the get go, it was clear that Anthony was very experienced, informative, and kind. Anthony was extremely communicative, providing updates and thoroughly explaining every step of the patenting process. I also appreciate how Anthony was genuine and approachable. We've just received our trademark registration certificate in the mail. We are very satisfied with his work and would recommend his services to anyone!

Exactly what I needed
Working with Anthony is great. I specified my situation and what I wanted. And he was very clear about what he'd deliver and at what cost. This completely eliminated ambiguity for me and I highly value that!

Very Helpful & Insightful
Anthony is fantastic. I was lucky enough to run into him at a Microsoft event, only weeks before my provisional patent was expiring. He quickly helped us complete our application and file before our provisional expired. I would highly recommend working with Anthony and plan to use him for all of our patent needs in the future.

Pulsed Hydraulics Reference
Anthony Claiborne was originally retained by our company to handle patents. Over an eight-year period, he filed and obtained eight patents on our behalf. Some were very complex and required substantial research. We moved our patent business to Anthony from another attorney and are glad he is returning to practice law as we had an excellent relationship and look forward to working with him in the future.

High marks!
I hired Anthony Claiborne in 2018 to get the rights to my book back from the publisher, who had defaulted on royalty payments and was not responding to my phone calls. In relatively short order, Mr. Claiborne successfully negotiated terms with the publisher and I won the rights back. I found him to be very responsive and helpful. I never felt I was being put on the "back burner" or ignored. I couldn't be happier with the process and the result.

design patent
I hired Anthony to help me file a patent. I spoke with him over the phone and explained my design to him and provided him with patent drawings. With the information from our discussion, and the drawings, Anthony was able to put together and submit a design patent application. Anthony kept me informed throughout the whole application process and answered any questions I had along the way. My design is currently patent pending. I am anxiously waiting for the approval.
