When is the Patent opposition filed in Japan?

From April 1, 2015 onwards, two patent opposition procedures are available:

  • Invalidation trial request:  This request can be filed by interested parties any time after grant (and even after the patent has expired), challenging one or more claims of a patent.
  • Opposition procedure: It can be initiated by anyone, but only within six months from the publication of granted patent.
