A number of jursidictions are now allowing software and business methods to be patented. These include the United States and Japan. Information on Canadian patent legislation as it relates to technology which utilize the processing function of a computer is found in the Manual of Patent Office Practice Chapter 16.
Under the European Patent Convention and the patent laws of a number of countries members of the European Patent Organisation, computer programs and business methods as such are still expressly excluded from patent protection.
In practice, however, the approach has changed in recent years as the result of long-lasting intensive and controversial discussions and many decisions. The vast majority of applications are today considered not to claim abstract programs or business methods but to describe technical means like, for example, computer networks, for carrying out these programs or methods.
