Section 90 – THE PATENTS ACT, 1970

(1) In settling the terms and conditions of a
licence under section 84, the Controller shall endeavour to secure—
(i) that the royalty and other remuneration, if any, reserved to the patentee or other
person beneficially entitled to the patent, is reasonable, having regard to the nature
of the invention, the expenditure incurred by the patentee in making the invention
or in developing it and obtaining a patent and keeping it in force and other relevant
factors;
(ii) that the patented invention is worked to the fullest extent by the person to whom
the licence is granted and with reasonable profit to him;
(iii) that the patented articles are made available to the public at reasonably affordable
prices;
(iv) that the licence granted is a non-exclusive licence;
(v) that the right of the licensee is non-assignable;
(vi) that the licence is for the balance term of the patent unless a shorter term is
consistent with public interest;
(vii) that the licence is granted with a predominant purpose of supply in the Indian market
and that the licensee may also export the patented product if need be in accordance
with the provisions of sub-clause (iii) of clause (a) of sub-section (7) of section 84;
(viii) that in the case of semi-conductor technology, the licence granted is to work the
invention for public non-commercial use;
(ix) that in case the licence is granted to remedy a practice etermined after judicial or
administrative process to be anti-competitive, the licensee shall be permitted to
export the patented product, if need be.
(2) No licence granted by the Controller shall authorise the licensee to import the patented
article or an article or substance made by a patented process from abroad where such
importation would, but for such authorisation, constitute an infringement of the rights of
the patentee.
(3) Notwithstanding anything contained in sub-section (2), the Central Government may, if in
its opinion it is necessary so to do, in the public interest,direct the Controller at any time to
authorise any licensee in respect of a patent to import the patented article or an article or
substance made by a patented process from abroad (subject to such conditions as it
considers necessary to impose relating among other matters to the royalty and other
remuneration, if any, payable to the patentee, the quantum of import, the sale price of the
imported article and the period of importation), and thereupon the Controller shall give
effect to the directions.
