The law recognizes trademarks as property and grants to the trader an exclusive right to use an individual mark.
One way to lose the right to a trademark is to abandon its use or fail to renew registration.
Loss of trademark right can also occur when it is transformed or when a term degenerates into a household name, as has happened with such well-known former trademark names as aspirin, cellophane, dry Ice, shredded wheat, thermos, and others.
