Bajaj has received a patent for a new technology, which has been a bone of contention with rival TVS Motor Co. Earlier, BAL had applied for patent of this technology in 2004. Later, TVS unveiled a series of new products, which Bajaj alleged of patent infringement of its ExhausTEC technology and served notice to the Chennai-based firm in December, 2007.
“The Indian Patent Office granted Bajaj Auto a patent for its ‘ExhausTEC’ invention vide Patent No 231498 dated March 5, 2009. This grant was published in Patent Gazette, dated March 27, 2009,” Bajaj Auto Ltd (BAL) Vice-President (Business Development) S Ravikumar said.
Bajaj Auto claimed that ExhausTEC significantly improves low- and mid-range torque (tendency of a force to rotate an object about an axis) in a single cylinder four stroke engine, employing a chamber of predetermined volume attached to the exhaust pipe.
