Did you give up the patent right from the beginning?

Depending on the specific circumstances, the termination of the patent right due to the expiration of the protection period or the abandonment of the patent right by the patentee only shows that the patent right is no longer protected by law, but the legitimacy of the patent right cannot be denied, because all legal relations that occurred before the patent right are valid. However, the patent right declared invalid is not invalid from the date of invalidation, but is regarded as invalid from the beginning.
