Once you register a trademark, you can use an R symbol along with it, and it will be valid till 10 years from the date of registration. You can easily get a ™ within 2 days. But, to get an ®, it takes up to 3 months. According to the trademark rules of India, items like sound, logo, words, phrases, colours, images, symbols, initials or a combination of all these can be trademarked.
