ThyssenKrupp Elastomertechnik has issued a statement suggesting that it is considering legal action against Yiyang Rubber and Plastics Machinery Group Co. Ltd for infringement of copyright.
TKE and Yiyang previously had a licence agreement under which Yiyang made machinery for Werner & Pfleiderer. That agreement expired in 1996, and was never renewed. When the agreement lapsed, Yiyag lost all rightsd to the Werner & Pfleiderer name, said a TKE statement.
TKE said Yiyang is now selling equipment bearing the W&P logo in many parts of the world, and this equipment is based on 1980s technology, with no improvements, such as crack-free hard coating and PES 5 intermeshing geometry.
This is potentially damaging to the W&P name, said TKE. It reminds customers that TKE has no relationship with Yiyang, and Yiyang has no rights to the W&P name, logo or technology.
