Dear sir
As per section 109(2)
"In any suit for infringement of a patent by the holder of an exclusive licence under sub-section (1), the patentee shall, unless he has joined as a plaintiff in the suit, be added as 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."
Does this mean if the patentee does not take part in the proceedings shall be liable for costs.
