On the rights and interests of patents

The patent itself is only a technical document and does not involve the distribution of rights. If you want to have some rights, you can draft another contract.

According to you, it is still uncertain whether it is a service invention. If it is a service invention, the applicant can only be the company, not you. Your right is to be an inventor, and you can get a reward or reward (if the product is produced, it is a reward), which the company should give you.
