Sudarshan Chemicals wins patent case against Clariant

Pune based pigment producer company Sudarshan Chemicals Ltd has won a patent case against German pigment manufacturer Clariant Produkte which was claiming that Sudarshan pigment, SudafastR Yellow 132 (PY191) has infringed its patent, Sudarshan said in a statement. It was also held that Clariant had issued unlawful threats to potential customers of Sudarshan.

The court will now assess damages to be paid by Clariant to Sudarshan as a result of its wrongful threats.

The court specifically stated that Sudarshan did not infringe Clariant's patent. The judgement was given by European Court of Justice based in Luxembourg in June 2012. The court also accepted that Sudarshan suffered severe losses during the period of three years, due to the discontinuation of exports of SudafastR Yellow 132, and compensation damages will have to be paid by Clariant to Sudarshan.
