Peter Prescott QC, sitting as a Deputy Judge in the UK High Court, noted that the EPO decisions are prescriptive, but not binding on the UK courts. With this in mind, the EPO's reliance on the word "technical" was criticised, but the judgment went on to say that the two modes of reasoning used by the UK courts and by the EPO, although different, would usually produce identical results on the same set of facts if properly applied. Another criticism suggests that the EPO are being too strict by insisting that an invention must provide a technical contribution to be inventive since, as evidenced by the judgment in Dyson v Hoover, the commercial background to an invention may be important when determining the presence or otherwise of an inventive step.
