I think our customer service speaks for itself. Give us, or have that someone you're trying to convince give us call or chat with us on our website live Monday-Friday 10AM-7PM. We'll happily answer your questions or get you in the right direction. Success rate is tough to answer when it comes to patents and trademarks. That is because the success is not necessarily tied to performance but more so tied to what your invention is. If you invent a cure for cancer, you're success is going to be 100%! For provisional patent apps, they are not examined by the US Patent Office and so we can guarantee it 100% that you will get "patent pending" status or we'll fix it. For full non-provisional utility patent apps, however, it's up to the patent examiner at the US Patent Office to decide if he or she thinks your invention is unique enough.
