Any registered trademark which is not renewed will be in the expired category. However, the registrar will not allot such mark for a period of 1 year from the date of expiry. Hence you can apply for renewal for your mark. However, there will be a penalty that will be levied in that case. After 12 months of expiry of the mark, if the application for renewal is not made, such marks come under the abandoned category. Anyone is free to register such mark.
