Case law on the assessment of computer-implemented inventions can give the impression that prosecution of these cases involves different considerations from other inventions. It is this barrier that causes most problems for computer-implemented inventions at the EPO. A potential technical effect is a downstream effect in a technical process that is dependent upon certain conditions. SufficiencyThe consideration of sufficiency of disclosure is also the same for computer-implemented inventions as in other fields. However, the patentability of computer-implemented inventions is certainly possible and is based on the same first principles as any other invention.
