Patent Oppositions

Patent Oppositions & Disputes

Once a patent is granted by the European Patent Office (EPO) there is a nine month window in which it can be challenged using the EPO Oppositions procedure. Follow this link for an outline of how the procedure works.

EPO opposition proceedings, if fully successful, automatically lead to total revocation of the European patent in all of the countries in which it has been validated. For an opponent this presents the opportunity for a very targeted attack on a competitor patent. For a patentee it presents considerable risk that rights will be lost or restricted throughout Europe. There is usually a great deal at stake in an Oppositions Procedure – and whether you are challenging or defending a patent you need a really experienced European Patent Attorney to maximize your chances of success.

We have one of the most experienced and successful patent oppositions teams in Europe. We have more than a dozen practitioners who regularly undertake oppositions work and at any given time we have upwards of 50 opposition cases in track. We are also accustomed to acting in Appeal Proceedings and can provide “Straw Man” services enabling a patent to be opposed without the identity of the patent opponent being disclosed (useful in a wide range of commercial circumstances). You can find profiles of our Patent Oppositions experts in the panel on the right.

Our offices in Munich and The Netherlands have been established to support our oppositions practice and are located close to the EPO buildings. Our patent attorneys are able to form constructive working relationships with EPO administration staff and with members of the Oppositions Divisions and the Boards of Appeal, and to keep up to date with changes in  procedural rules and working practices. Both offices can provide amenities for attorneys from other parts of Haseltine Lake Kempner and for their clients when preparing for Oppositions Proceedings.
