Patents Act, 1970
110. Right of licensee under section 84 to take proceedings
against infringement
Any person to whom a license has been granted under section 84
shall be entitled to call upon the patentee to take proceedings to prevent any
infringement of the patent, and, if the patentee refuses or neglects to do so
within two months after being so called upon, the licensee may institute
proceedings for the infringement in his own name as though he were the
patentee, making the patentee a defendant; but a patentee so added as defendant
shall not be liable for any costs unless he enters an appearance and takes part
in the proceedings.
