A Trademark is a sign that is able to distinguish one enterprise’s goods from those of other enterprises. It is granted for a period of 10 years and can be renewed for every 10 years. Over time Trademark becomes synonymous with a company name, so that you don’t even need to see the name to recognize a particular business.Once a Trademark is granted to the owner then he can claim over it if he finds some third person using his (same) name by suing him in court or can also claim compensation from him.
