A trademark is a distinctive sign, symbol, word, phrase, logo, design, colour combination or combination thereof that identifies and distinguishes the goods or services of one business from those of others. Once registered, a trademark gives the owner the exclusive right to use it for the specified goods/services in India and take legal action against anyone who uses it without permission.
Under the Trade Marks Act 1999, trademarks can include: words (brand names), logos and device marks, slogans and taglines, 3D shapes of products, colour combinations (like Cadbury's purple), sound marks, and combinations of the above.
