EPO pilots online Third Party Observation (TPO) submission

On 1st August the European Patent Office (EPO) launched a pilot scheme which allows the submission of third party observations (TPOs) via an online form (accessible from the EPO website and linked from the EPO register).

TPOs allow third parties to comment on the patentability of a pending, published European application. There are no fees for doing so and observations may be made anonymously.

The EPO hopes that by facilitating and promoting the filing of well-structured and concise TPOs the quality of granted European patents will be improved and, in some cases, may lead to a reduction in the length of procedure.
