I'm very happy with Patent Services USA. I like that they know what they need to do every step of the way. I looked around and reached out to other companies, and most of them didn't have the answers to my questions. Patent USA had good answers. They are very knowledgeable, professional and they have good customer service, they almost call me too many times! But I'll have that before having to deal with some of the others companies that don't call me at all.
I'll give them a 10 out 10.
