We retained the services of pKorn Law with regard to the registration of several trademarks for our ice cream parlor in Los Angeles. Petra advised us and guided us through the entire process of the trademark application with ease. We now have two registered trademarks and have already retained pKorn Law for further trademark application. Petra provided us with an excellent professional service and made the whole process very smooth for us as the client. We can highly recommend working with pKorn Law.
