DuPont Narrows Scope of Patent Claim Against Heraeus

Share with Twitter Share with LinkedIn

WEST CONSHOHOCKEN, Pa., July 8, 2013 /PRNewswire/ -- Heraeus today announced important developments in the ongoing litigation with DuPont in Oregon.  The case is one of two involving patent claims by DuPont against Heraeus' solar cell pastes. The other case is pending in Delaware.

Significantly, when faced with Heraeus' motion for early termination of the lawsuit, DuPont was forced to narrow its claim, conceding that Heraeus' commercially available products do not literally infringe DuPont's patent.  DuPont's counsel stated on the record, "We do not assert literal infringement as to any of the products that are at issue in Heraeus' motion.  So that theory is simply not part of the case." This means that DuPont's allegations are now limited to a much weaker theory called the doctrine of equivalents, where the accused products do not fall within the literal scope of the patent-at-issue but are alleged to be similar enough for a finding of infringement.

While litigation is a lengthy process, and the case is not likely to be resolved soon, Heraeus believes it does not infringe any valid claim of the patent at issue.
