Patents Act, 1992

Power of Court to make declaration as to non-infringement.

54.—(1) A declaration that the use by any person of any process, or the making or use or sale by any person of any product, does not and would not constitute an act of infringement of a patent may be made by the Court in proceedings between the person and the proprietor of the patent or the holder of an exclusive licence under the patent, notwithstanding the fact that no assertion to the contrary has been made by the proprietor or licensee, if it is shown that—

(a) the plaintiff has applied in writing to the proprietor or licensee for a written acknowledgement the effect of which, if given, would be similar to that of the declaration claimed, and has furnished him with full particulars in writing of the process or product in question; and

(b) the proprietor or licensee has refused or neglected to give such an acknowledgement.

(2) The costs of all parties in proceedings for a declaration made by virtue of this section shall, unless for special reasons the Court thinks fit to order otherwise, be paid by the plaintiff.

(3) The validity of a patent in whole or in part shall not be called in question in proceedings for a declaration made by virtue of this section, and accordingly the making or refusal of such a declaration in the case of a patent shall not be deemed to imply that the patent is valid.
