Three Far Eastern manufacturers had their machines removed from this week's Bauma construction equipment show in Munich for product copying and patent infringements.
JCB successfully applied for court orders in Germany resulting in preliminary injunctions being served against manufacturers who were exhibiting the infringing machines.
As a result of the tough action, the machines had to be either removed from the show and impounded or concealed from view.
Tim Burnhope, JCB's group managing director of product development and commercial operations, said: "JCB will not tolerate blatant copying of its machines or infringement of internationally-recognised patents and in every instance will act quickly and decisively to stamp out such unfair practices.
“JCB invests many years and many millions of pounds developing and innovating new products and it's clearly unfair for any manufacturer to then simply free-ride on the results of that investment and research. As an industry we all have to unite to prevent such unlawful practices. "
The action in Germany concerned infringement of JCB’s intellectual property rights on its world-leading backhoe loader and Loadall machines by three separate Far Eastern manufacturers.
