The biggest similarity between the two is that both have authorized patents. The difference is: the concept of patent authorization amount is greater than the patent ownership amount, that is, the authorization amount includes the ownership amount. The reason is that the patent after authorization may have different legal consequences due to specific legal reasons, such as 1. being invalidated. The patent after invalidation is invalid from the beginning, but because it has been authorized before, it will be counted in the authorization amount. 2. Considered as giving up. Patents require the payment of annual fees. If the annual fees are expired and the annual fees are not paid, the authorized patent will be deemed to have been abandoned. 3. The patent protection period expires. Patents have a protection period, which is 10 years for utility models and designs, and 20 years for invention patents, which are calculated from the date of application. After the patent expires, it becomes invalid and can be used by anyone. The above three situations cannot be counted in the ownership. The ownership refers to the patents that are still valid at the time of calculation. The intellectual property service team is here to answer your questions and hope to help you
