So far, I am really enjoying using Patent Services USA. They are currently helping me to get a patent pending, and helping me to manufacture an invention product. This is my first time using them and the staff has been great. When I decided to get a patent, I contacted several companies and they were the only ones to call me back. They're available right when you need them and I don't have to wait for them to respond if I have a question. When I reach out to them, whether through e-mail or phone, they always respond immediately and provide great service. I hope they continue to do a great job and I would absolutely recommend them to future customers. They have prompt service, they are very friendly, and I can tell that they are up to speed with the work that they do. Everything has been going very well up to this point, so I'm happy!
