The machines were either removed from the show and impounded or concealed from view as a result of the action.
JCB group managing director of product development and commercial operations Tim Burnhope 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 Backhoe Loader and Loadall machines by three separate Far Eastern manufacturers.
