I have my own company, and then the patent is granted to a company to operate. Can I continue to use it myself, or continue to authorize other companies? Nonexclusive grant

General patent authorization won't restrict me or authorize me to other companies, only myself and the authorized company can use it exclusively ~ unless there are clear conditions when signing the contract that I won't use the patent after authorization ~ (generally I won't do this ~ it's no different from selling patents) and the exclusive authorization time won't be too long ~ generally 1 year, 3 years, 5 years. Will not exceed 10 years (loss)
