The application related to a process control system which used program objects corresponding to components of the process to provide information to an operator. The hearing officer followed the four-step approach to the assessment of patentability under section 1(2) approved by the Court of Appeal in Aerotel/Macrossan [2006] EWCA Civ 1371 in determining whether the invention was excluded from patentability. He held that claims to a workstation with the objects stored on it were excluded as claims to a computer program, but claims to a process control system comprising the objects were held not to be excluded.
