Tennant GmbH & Co. KG has applied to the Regional Court in Stuttgart for a further extension of the deadline for the statement of defence to 7 December 2011. The request was granted.
The reason given by Tennant for this request for an extension of the deadline is that expert opinion was currently being compiled by the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB). The subject under examination was the effectiveness of the ec-H2O technology.
Till now, Tennant had publicly maintained that the effectiveness of the so-called ec-H2O technology had already some time ago been substantiated by several studies.
