PATENTS
At Chandrakant M. Joshi, we safeguard innovation through end-to-end patent law services — from idea assessment to registration, enforcement, and renewal. Our approach ensures every invention receives strong, practical, and enforceable protection in India and across international jurisdictions.
A patent grants inventors exclusive rights over their creation — preventing unauthorized making, using, or selling of the invention. Governed by the Patents Act, 1970 and Patents Rules, 2003, patent protection strengthens business value, encourages research, and drives technological growth.
Our team blends technical expertise with legal insight to deliver results across industries such as pharmaceuticals, chemicals, electronics, software, mechanical engineering, and biotechnology.
