I and my invention/product development firm have been working w Cislo & Thomas for years. We love these folks! They are professional, ethically of the very highest caliber, professional, etc. Of course they're human and sometimes unexpected things happen - that is true of every business, including every law firm w which we've ever worked. Having myself been involved w (way too) many patents, tm's etc. - I'd recommend these folks highly. Dan Cislo knows law well! And he sets the tone for professionalism and character. Wook Pak is a spectacularly brilliant patent atty - perhaps the smartest patent guy I've ever worked w over my many years. He listens, he learns your invention and your goals, he is articulate and sober, and he grounds you in the realities of patent law. Katherine's great as well - a notably sharp and responsive communicator. And the support staff is just what you'd want - sharp and nice folks who want clients satisfied.

The entire team at Cislo & Thomas, LLP is brilliant, but a big shoutout to Dr. Wook Pak! Wook not only helped me attain my patents quickly and efficiently, but has also been a mentor and friend. I appreciate all the hard work and highly recommend Wook for his professionalism, quick responses, guidance, and expertise.

Wook Pak and Dan Cislo have helped me acquire two patents with two additional patents in process. The patents are for the method of use and the method of production of a functional food/supplement. Patents on functional foods are extremely rare and hard to acquire, but with their help I was able to achieve what most other patent attorneys would consider extremely difficult if not impossible. Their council has been invaluable and I have complete trust and confidence in their legal guidance. Their work is nothing but top tier and their approach is both creative and highly thoughtful. I strongly recommend Cislo & Thomas for any of your IP work. they will simplify the process for you and help you obtain your IP in a efficient and effective manner.

Dr. Wook Pak was great to work with. Not only did he do a fantastic job of walking us through the patent process, he was patient and provided quality service. He was accessible, responsive, and genuine. Highly recommend Dr. Wook Pak and Cislo & Thomas LLP.

Dan Cislo and his group of experts in Trademark and Patent law have been outstanding for me as an inventor and my group, Hall Innovations, LLC here in Southern California. They go above and beyond to help you understand the pertinent laws and stay on top of all of our very important filings and issues. I have 6 patents either pending or in current status and probably 10 or more trademarks. I couldn't be more happy and pleased with the service they provide. They truly are worth every dime spent as Intellectual Property is so important to protect and have as a manufacter and entrepreneur. I would fully endorse this great law firm.
