Cislo & Thomas LLP

Customer Testimonials The whole Cislo & Thomas, LLP team has been incredible, especially Dr. Wook Pak! Wook not only helped me achieve my patents quickly and effectively, but he has also been a mentor and friend. I appreciate all the hard work and recommend Wook for his work ethic, quick communication, guiding nature, and knowledge. Brain F. My firm, an invention/product development organization, has been with Cislo & Thomas for many years. We love these guys! They are professional, ethical, and so forth. Of course, they are human, and sometimes unexpected things happen—an every business, including every law firm we have worked with. Having been involved in too many patents and trademarks, I highly recommend them. Dan Cislo knows law. He sets the tone for professionalism and character. Wook Pak is an amazing and smart patent attorney, probably the best patent guy I've ever worked with. The support staff is also great, sharp, and friendly. Joe C. Wook Pak's and Dan Cislo's assistance has led to the acquisition of two patents, with two more in the works. My patents cover a food/supplement functional usage and production. Functional food patents are scarce, and obtaining them is difficult, but with their help, I was able to achieve what other patent attorneys consider impossible. Their expertise was priceless, and I trust them. Their work is top-notch, and their approach is creative and thoughtful. Patents do not always guarantee success, but I trust KC's legal guidance. Shawn H. Dr. Wook Pak was a pleasure to deal with. He was very professional when guiding us through the patent process. He was very attentive, communicative, and authentic. Dr. Wook Pak and Cislo & Thomas LLP highly recommend. Rick G. Cislo & Thomas has done all of the IP work for my company (The Black Tux); they have always provided great advice, fair prices, and are a pleasure to work with. I recommend them for patent, trademarks, or IP litigation. Andrew B. Dan Cislo and his team of experts in Trademark and Patent law have provided outstanding help for me as an inventor. They go above and beyond to help you understand the laws, filings, and IPRs. I have six patents in waiting or status and ten or more trademarks. It is the best law firm. Dr. Raymond Hall, DC, PILLO1
