Blow of the Hammer – Heuking Kühn Lüer Wojtek Obtains Preliminary Injunction at "bauma 2010" Trade Show against Patent-Infringing Pile Driving Rig with Laser Measuring System

Heuking Kühn Lüer Wojtek's Düsseldorf-based patent law team jointly with the Düsseldorf patent attorneys of COHAUSZ & FLORACK obtained a preliminary injunction at Munich I Regional Court (presiding judge Dr. Peter Guntz) during the "bauma 2010" trade show on behalf of CP Test A/S which is part of Danish group Per Aarsleff A/S.

The preliminary injunction is based on the infringement of patent EP 0 737 262 B2 by Finnish company Junttan Oy, which offered a patent-infringing pile driving rig with laser measuring system at the open-air ground of "bauma", the world's largest trade show for construction machinery. CP Test A/S had previously developed and patented a corresponding system. It was possible to serve and enforce the preliminary injunction still during the trade show at Junttan Oy's booth.

The infringed patent concerns a system for pile driving rigs which drive down piles into the ground by hammer blows. A laser measuring system determines the penetration of the piles due to each blow of the hammer and thus also allows gaining reliable information on the load-bearing capabilities of various underground strata.

An appeal may be filed against the temporary injunction which only represents an interim court order.

Law firm of Heuking Kühn Lüer Wojtek, Düsseldorf; Dr. Anton Horn (Partner) and Melanie Künzel, LL.M. (Associate);
