Trademark maintenance involves actions that people or businesses take to keep their registered trademarks valid. Trademark maintenance generally consists of one or more of four elements, viz., payment of renewal fee, issue of a cautionary notice, submission of an affidavit of use, and docketing of proof of renewal of basic registration.
• The payment of renewal fee is generally performed every ten years (10) from the date of registration.
• A cautionary notice is used in some countries to show ownership of a trademark.
• The affidavit of use (also called a statement of use) is typically filed with the payment of renewal fee.
• The receipt issued by the Trademark Office, after the payment of the renewal fee, is docketed as proof of renewal of the first registration.
