The Taiwan Intellectual Property Office (TIPO) amended the “Joint interview program for related invention patent applications”, which came into force on May 10, 2013. According to the original program announced on October 1, 2012, the TIPO would promulgate the IPC groups applicable to the related invention patent applications for the joint review program in January and July of each year based on the date on which the request for substantive examination was filed. Under the amended program, the limitation to the IPC groups has been removed so that the applicants are encouraged to apply for the joint review grogram to expedite the examination of patent applications.
