Intellectual Property High Court Procedure Overview

The Japan Patent Office (JPO) appeal board functions as the court of first instance, and appeal decisions made on an appeal against a Final Decision of Rejection made by the JPO are subject to review by the Intellectual Property High Court (IPHC). The IPHC is a special branch of the Tokyo High Court that handles both ex parte and inter partes cases. If the IPHC finds that an appeal decision made by the JPO erred, and a judgment to rescind the Appeal Decision is finalized, and the procedure is returned to the JPO’s three-examiner Appeal Board for re-examination.

Duration

The average duration from commencement to disposition for ex parte suits handled by the IPHC in 2013 was 7.6 months. It was 12.4 months in 2003, and the duration has been declining steadily every year, according to the report made by the Administrative Bureau of Supreme Court of Japan in 2014.

Success Rate

According to the statistics reported by the JPO in 2013, 174 ex parte suits were filed with the IPHC in 2012. In the same year, 115 cases were dismissed and 37 cases were successfully returned to the JPO. This makes the average success rate of 24% in 2012. According to the report, the success rate in 2010 was approximately 22% and it was approximately 20% in 2011.
