granted or the endorsement "licenses of right" has been made or is
deemed to have been made, the Central Government or any person interested- may,
after the expiration of two years from the date of the order granting the first
compulsory license or, as the case may be, the date of the grant of the first

invention is not available to the public at a reasonable price.
(2) Every application under sub-section (1) shall contain such
particulars as may be prescribed and the facts upon which the application is
based and, in the case of an application other than by the Central Government,
shall also set out the nature of the applicant's interest.
(3) The Controller, if satisfied that the reasonable
requirements of the public with respect to the patented invention have not been
satisfied or that the patented invention is not available to the public at a
reasonable price, may make an order revoking the patent.
(4) Every application under sub-section (1) shall ordinarily be
