When applicants appeal Korean Industrial Property Tribunal (KIPT) decisions on unpatentability matters to the Korean Patent Court (KPC), they are usually frustrated at the decisions made by the court. Considering that most of judges at the KPC have limited technical background, it is extremely difficult for an appellant to persuade judges to overturn a KIPT decision sustaining the examiner´ s rejection on a patent application by discussing complex technical principles and theories as to why such an invention should be patentable. In other words, judges at the KPC customarily defer the technical aspects of an invention, ie whether an invention is patentable, to the KIPT because the KIPT is comprised of technical experts whose decisions are usually supported with precise and accurate technical reasons.
