What if my invention contains someone else's patent?

1, inquire about the patent status and whether it has expired. If it has expired, you can continue to apply for a patent normally.

2. The patent is not invalid. Under normal use, then you can only obtain the patent authorization or purchase the patent use right. Otherwise there will be the possibility of patent infringement.

If the technical scheme of the original patent is simply combined and the two patents still work independently, then the invention will not be novel and creative, and such an invention will not be approved or authorized to apply for a patent.
