After you've submitted your application
Keeping your trade mark registered
Once your trade mark is granted, your first renewal documents needs to be filed between the fifth and sixth years after registration. Your next renewal documents are due between the ninth and tenth years after registration, or four years after your first renewal. From then, you can renew your trade mark every ten years indefinitely; however you will need to prove that you are still using the mark in commerce at regular intervals. If you don’t use it, you will lose it!
If you miss the filing deadline there is a grace period of six months to file the maintenance documents, however this does incur additional fees. If you miss both the initial filing date and the grace period your trade mark will expire and you will have to file a new application.
