Special rules pertain when you invent something while working for a company, and depending upon the patent trademark law of the state you live in, it may be difficult for you to make a cent off such an invention. Even if you invent something in your spare time your company may have a claim on it, so be sure to consult a patent attorney before you patent anything.

Even the best patent attorney can't help you if you don't cooperate fully. Patent trademark law is complex and can require a great deal of information and research, so don't feel pestered if your attorney is always contacting you. It's all in your best interest, after all.

Patent trademark law is very particular when it comes to names, so be sure to make a thorough search before you attempt to trademark a name for any invention, process, or item. Many companies won't bother to sue even so, but they might if they think your using their trademarked name might harm them in some way.
