Patent Renewal
Patents become public at the end of the protection period. It can be explained as the annual payment of patent or utility model applications with patent renewal.
If the annual fees for the patent or utility models are not paid on time, the patent or utility model becomes invalid.
Most of the applications made are due to not tracking annual fees. Choosing patent companies that have the necessary hardware and software for application follow-up will allow you to retain the rights you have earned with intensive labor and money.
