DuPont denied in request for preliminary injunction against MacDermid

MacDermid has announced that for the second time the Federal District Court in New Jersey, USA, has denied DuPont’s motion for a preliminary injunction.

This decision is part of a 2006 photopolymer plate patent infringement law suit in which DuPont sought preliminary injunction against certain MacDermid thermally developed flexographic printing products. MacDermid markets its thermal equipment under the LAVA trade name.

In its rulings, the court found that MacDermid has raised substantial questions regarding whether the ‘859 patent (DuPont’s US Patent No 6,773,859) is invalid and that DuPont failed to show that MacDermid’s defense that the patent is invalid was unwarranted. The court concluded that there are substantial questions regarding whether the ‘859 patent was an ‘obvious combination of elements in the prior art’.

Michael Siegmund, president, MacDermid Printing Solutions, said, ‘MacDermid is a technology-based company that makes a considerable investment in R&D. Our philosophy, culture and business practices are such that we would not, and do not, knowingly infringe any valid patent.’

Scot Benson, vice president sales added, ‘This has been our stance from the beginning. We were very confident that the court would continue to uphold our position; and they have.’
