Kaustubh Nadkarni’s firm was always extremely user friendly and prompt. Every time I called his office; I would get an immediate response. His rates are quite reasonable and he held my hand through entire trademark process. My trademarks are secured and I’m very happy to recommend him to anyone who n eeds a trademark. He’s actually a one stop shop; as a result, I will use him my all of my business needs.

Mr.Kautsubh helped us register our brand! We tried to do this for 3 years with different lawyers and were refused. We wasted money and time. He carefully studied our case and gave us recommendations on how to get a result. We submitted new application with him and he was absolutely right! We regist ered the logo and then the word! Now we have a two registered trademarks! Kaustubh Nadkarni is honest, professional lawyer at a very reasonable price. We had a very difficult case and he helped us to get the result!!! Thank you so much! Excellent job! Highly recommend to everyone!

John Rizvi is a great patent attorney. When you work with him, you can appreciate his knowledge and passion with working with inventors and protecting their intellectual property. One thing I also appreciated about John was how he was able to write the patent in such a way to make sure that the paten t didn't get in the way of the invention process. This is good because as you work through the invention phase, its hard to say were the discovery will take you. New discovery may fall outside the patent. However, as the patent was written it allowed for some wriggle room. He has a great team and his team was nice and cordial when I was working with them to get the patent done. He has a great book called "Escaping the Gray." He sent this book to me once I became his client. When I started reading that book it was hard for me to put it down until I finished it. When I feel like I need some motivation, I think back on some of the exerts of that book of his own life experiences and it helps me keep trudging forward. He wrote that book for entrepreneurs. And his own experience of walking off the deep end and taking that big risk and how he had to cope with fear to help him move forward. Also from reading the book, he helps us inventors know that he knows how important our idea is to us, and how escaping the gray and transforming from inventor to entrepreneur is a journey well worth it!

My initial communication with John Rizvi’s office and staff was an introduction to what would manifest. From start to file, each phase and conversation was clear, upfront, and honest. Timelines, meetings and responses were kept and consistent. John, along with Noah, Ana, Giovanni and all displayed ef ficiency in their department of skill. The patent process was clean and thorough, allowing for ultimate comfort throughout. I’d absolutely recommend to anyone hoping to patent their idea(s).
