Abstract:It has been a controversial issue whether to introduce patent infringement punitive damage originated from English Law in Tai Wan region of PRC.. The evolution route for patent infringement punitive damage is not only the process of refuse firstly, then introducement, following abandonment, soon after re-establishment ,but also the reflection of attitude change for from those legislators towards patent protection in Tai Wan region. There are three material causes to explain why legislative authority has altered the attitude on patent infringement punitive damages so frequently and fundamental differently, namely as the incompatibility with the Civil Law and absence of non-operability in judicial practice, as well as lack of ability to take the legislative purpose to prevent patent from infringement. During the process of amending Patent Law in Mainland, it is better not to follow Tai Wan region when considering whether to introduce or to refuse the patent infringement punitive damages.
