Protection of IPRs of Four-Wheeler – Cars (Including Electric Cars) Manufacturing Companies Under Indian IPR Laws

The Indian four-wheeler automobile industry—spanning internal combustion engine (ICE) cars and the rapidly evolving electric vehicle (EV) segment—is highly innovation-driven. Automotive companies invest significantly in drivetrain technologies, electrification, battery chemistry, advanced electronics, autonomous and ADAS systems, telematics, industrial design, safety systems, and manufacturing processes.

To protect their innovations, investments, and brand reputation, auto manufacturers rely on India’s multi-layered IPR regime under patents, trademarks, designs, copyrights, semiconductor layout design laws, and trade-secret protection.

1. Relevant Indian IPR Laws for Car & EV Manufacturers
