An offence if it’s determined as collective crimes is a matter of assessing the norm and the purpose of punishment in terms of the explanation of elements of an offence we regard it as a single conduct in law. Although the object of evaluation could be one or several conducts of natural meanings, the result of the evaluation will be considered as a single unit. Performing over and over is nothing but a description of a phenomenon about the feature of the concept. There is no reason to reverse that legislator did not put the offence which is discussed predestinating the standpoints as several conducts into consider only because the copyright infringement by duplicated or spread might be done once. Even though the jurisdiction tried to carry out ”one offence, one punishment” policy expressed in the amendment of criminal law in 2005, there are still insufficient reasons to put plural acts as plural offences. Although the German Jurisdiction gives up using the concept collective crimes to serve ”unit” judgments, ”evaluation unit” has been developed as a result and applied for methods or ways which could comprise crimes. It is possible to work out ”evaluation unit” or to extend the concept of collective crimes while we solve the problem about how to determine the quantity of copyright infringement, not to mention the German copyright law has established the ”occupational crime” in Article 108a with intensive attention.
