Furthermore, normal legal proceedings must be instituted within 8 days of a seizure if evidence obtained in the seizure is to be used in those proceedings. Such orders can in some cases be obtained in a matter of a few weeks. The plaintiff may be required to post a bond against the possibility that he will not succeed at full trial. However, this is not generally required. The plaintiff should act fairly promptly after learning of an infringement if he is to succeed.
Proceedings leading to a full determination of the issues proceeds more slowly, however.
Typically, the court appoints an expert and each party will probably appoint its own expert to cooperate with the court expert. Each court keeps its own register of experts, although there is no requirement that the expert is selected from that list if the court gives its reason as to why it has selected someone else. The function of these experts is to answer questions put to them by the court. These questions are formulated at hearings between the judge and the parties. Under the court's supervision, the role of the expert may be wide ranging from giving in camera advice to the judges to carrying out his own independent technical evaluation of the issues in the case.
