EPO: T1691/15, European Patent Office (EPO), Board of Appeal, T1691/15, 27 July 2016

An EPO board held that, during opposition proceedings, copies of complaints about file specific issues sent by a party to EPO departments other than the opposition division, as well as the responses to these complaints, should be sent to the other party. The other party also needs to be notified of complaints about the work of the search and examining division, since the primary examiner forms part of the opposition division.
