the person seeking them, be calculated on the basis of the amount that an exclusive licensee would reasonably have been expected to pay under the circumstances for his use of the design concerned: Provided that, if the person seeking damages intends to exercise this option, he shall give notice of his intention, in writing, to any exclusive licensee of the registered design concerned. (3) In determining the amount of damages in an action for infringement of copyright in a registered design, the Tribunal or the court, as the case may be, shall take the following factors into account, in addition to all other material considerations¾ (a) the extent and nature of the infringement; and (b) the amount which could be payable to the proprietor in respect of the use of the design by some other person; and (c) any dilatory conduct on the part of the proprietor of the design or the plaintiff in making the infringer aware that the design was registered. (4) If it is established, in an action for infringement of copyright in a registered design, that an infringement was committed and the Tribunal or the court, having regard to¾ (a) the flagrancy of the infringement; and (b) any benefit shown to have accrued to the person responsible for the infringement as a result of it; is satisfied that effective relief would not otherwise be available to the plaintiff or applicant, the Tribunal or the court, as the case may be, shall have power to award such additional damages as it thinks fit. (5) If it is established, in an action for an infringement of copyright in a registered design, that an infringement was committed but that at the time of the infringement the person responsible for it was not aware and had no reasonable grounds for suspecting that he was not entitled to engage in the infringing activity, the plaintiff shall not be entitled under this section to any damages against that person in respect of the infringement. (6) Where¾ (a) there has been a change in the proprietorship of a registered design, whether through assignment, transmission, operation of law or otherwise; or (b) an exclusive licence has been granted in respect of a registered design; the new proprietor or co-proprietor or the exclusive licensee, as the case may be, shall not be entitled to recover damages for any infringement of the copyright in that design which occurred during the period from the change in the proprietorship or the grant of the exclusive licence, as the case may be, until the change or the grant was registered in terms of section twenty-two, unless the registration was effected within six months of the change or the grant.
