55. Invalid clauses in license contracts

Any clause or condition in a license contract shall be null and void in so far as it imposes upon the licensee, in industrial or commercial field, restrictions not derived from the rights conferred by this Part on the registered owner of an industrial design, or unnecessary for safeguarding of such rights :

Provided that—

restrictions concerning the scope, extent, or duration of use of the industrial design, or the geographical area in or the quality or quantity of the products in connection with which the industrial design may be used ; and

obligations imposed upon the licensee to refrain from all acts capable of prejudicing the validity of the registration of the industrial design, shall not be deemed to constitute such restrictions.
