Patents, on the other hand, give their owners the right to prevent others from using the technology defined by the patent claims, even if the technology was independently developed and there was no copying of a software or software code involved. In fact, one of the most recent EPO decisions clarifies the distinction, stating that software is patentable, because it is basically only a technical method executed on a computer, which is to be distinguished from the program itself for executing the method, the program being merely an expression of the method, and thus being copyrighted.
