Under Section 120 of the Patents Act, 1970, a person is liable if he falsely represents that:

Section 120 covers a person who "falsely represents that any article sold by him is patented in India or is the subject of an application for a patent in India". Both false claims are covered, but a claim of foreign patent rights is not, and holding oneself out as a patent agent is dealt with under sections 123 and 129.
