Hepp Wenger Ryffel AG
is taking over
Dr. Graf & Partner AG


We are here for you

Both firms have already cooperated closely on a case-by-case basis in recent years. When Werner Graf wished to retire from the day-to-day business, the succession arrangement that has now been found was an obvious choice. In close coordination, we were able to jointly prepare the handover on January 1, 2021, thus ensuring continuity. Werner Graf will continue to be available to us in an advisory capacity for a while, if required.

The whole team at Hepp Wenger Ryffel is looking forward to new exciting tasks!

Martin Wilming will be happy to answer any question you might have concerning the above.

Hepp Wenger Ryffel

We are one of the largest patent attorney firms in Switzerland. But self-praise is not our strong point. Here is what iam Patent 1000 recently wrote about us:

One of the elite patent attorney groups in Switzerland and internationally, Hepp Wenger Ryffel is an obvious choice for prosecution and technical support in the most challenging cases. They are wonderfully responsive, incredibly skilled across all areas and combine it all into a cost-effective package.

Werner Graf

Werner Graf will continue to coach some IP projects under the name ‘SWISSPATENT Consulting’.
