Yes. Under Article 115 EPC, any third party may file observations concerning the patentability of an invention claimed in a published European patent application. They must be filed in writing in an EPO official language (English, French or German), and must state the grounds on which they are based. There is no prescribed EPO form for this. The person submitting the observations is not a party to the patent grant proceedings, and is therefore not informed by the EPO about their further outcome.
The observations are communicated without delay to the applicant or proprietor, who may comment on them. If they call into question the patentability of the invention in whole or in part, they must be taken into account in any proceedings pending before a department of the EPO until such proceedings have been terminated, i.e. they must be admitted into the proceedings. If the observations relate to alleged prior art available other than from a document, e.g. from use, this should be taken into account only if the alleged facts either are not disputed by the applicant or proprietor or are established beyond reasonable doubt. Observations by third parties received after the conclusion of proceedings will not be taken into account and will simply be added to the file (see Guidelines for Examination, E-VI, point 3 and Rule 114 EPC).

Since 2 July 2012, third parties have been able to submit observations to the International Bureau about prior art in published PCT applications if they believe that the invention claimed lacks either novelty or inventive step. They can do this as from the date of the international publication and up to 28 months from the priority date. They can use WIPO’s ePCT system or the Patentscope search system.
As explained in WIPO's FAQs, observations are transmitted to any competent International Searching Authority, and/or International Preliminary Examining Authority involved in the processing of the application during the international phase, if the International Bureau has not yet received the international search report, supplementary international search report or international preliminary report on patentability (Chapter II of the PCT) respectively. To the extent that the observations are received by those Authorities in time to be taken into account in drawing up their respective reports, any prior art referred to in the observations should be considered, provided that either a copy of the prior art is included, or it is otherwise immediately available to the examiner. The observations are also transmitted to the designated Offices promptly after the expiration of 30 months from the priority date. The designated Offices are, however, not obliged to take them into account during national processing.
For more general information about third-party observations in the international phase, see WIPO's FAQ , or contact WIPO's PCT Information Service as follows:
