The appellant (Zietsman) instituted action in the court of the Commissioner of Patents against three respondents for damages for alleged infringement of his South African patent no 92/9925. The respondents failed to deliver their pleas timeously and were barred from doing so. They applied for removal of bar, extension of time to plead, and for security for costs. The appellant had offered security of R40,000 to each of the first and second respondents. Regarding the third respondent, there was correspondence in which the appellant agreed to provide security (with quantum contested), and the third respondent demanded R250,000. The Commissioner of Patents (De Vos J) directed the appellant to provide security for costs to all respondents in the amount of R250,000, removed the bar, granted extension of time, and ordered the appellant to pay costs including costs of two counsel. The appellant appealed against the security order and the costs orders.
