In the case of infringement of patent rights, patentee can institute ................ in competent court.

Under Sections 104 and 108 of the Patents Act, 1970 a patentee enforces his rights by a "Civil suit" for infringement in a District Court or High Court, seeking an injunction and damages or an account of profits. Patent infringement is not a criminal offence under the Act, so a "Criminal complaint" does not lie.
