Some trademarks cannot be registered in India. Some common reasons when a trademark in India cannot be registered are:

• If they lack distinctiveness and likely to cause deception or confusion;
• If they are likely to hurt religious sentiments of any community;
• If they contain any scandalous or obscene matter cannot be registered either;
• Trademarks that are prohibited under the Emblems and Names Act, 1950;
• Trademarks of shapes which are purely functional or necessary to obtain a technical result or which give substantial value to the goods.
