The small car developed by Tata Motors is another milestone in evolution of automobile sector in India from imitators to innovators. The number of patents filed by the six top local auto makers in the country jumped 85 per cent in just 18 months since January 2005 against the 10-year period between Januray 1995 and December 2004, according to data from Evalueserve, a firm that tracks patent filings.In contrast, companies like Maruti Suzuki, Hero Honda and Ashok Leyland (which has a tie-up with Iveco) that depend on their global partners for the bulk of their technology account for just 2 per cent of all patents filed.
Among the companies, Chennai-based TVS Motors, is the leader in terms of the sheer volume of patent filings in Indi - the company has filed 131 patents to the Indian Patent Office since January 1995, of which 70 per cent have been filed since January 2005, speeding up after its joint venture with Suzuki ended in 2001.However, when it comes to the success rate, Tata Motors takes the top honours, with the ratio between patents filed and issued at 60 per cent.
