"In the 1990s, applicants started to formulate claims for their computer implemented inventions in terms of the computer program, e.g. ‘Computer program for carrying out method X’ or ‘Computer readable medium for storing a computer program for carrying out method X’. The latter formulation and equivalents are referred to as a computer program product claims (CPPs). These formulations are clearly important for applicants as they are routinely included in patent applications in the field of computer technology. In this field, claim formulations along the following lines are common: * methods * systems (i.e. computer systems) * computer-implemented methods * computer programs * computer program products, storing a computer program."
