Patent infringement suit from 2012 resolved; PSI's CSC-BF Continuous Backflush Screen Changer design does not infringe.

PSI-Polymer Systems Inc. Conover, N.C.  has reached an out of court settlement with Nordson PPS GmbH on a patent conflict originally filed by Kreyenborg GmbH against PSI in 2012.  The original lawsuit alleged that PSI’s CSC-BF Continuous Backflush Screen Changers infringed Kreyenborg’s patents. 

A Joint Motion to Dismiss with Prejudice was filed in the U.S. District Court, Western District of North Carolina, Statesville Division on September 5, 2014, stating that both parties had resolved and settled their disputes.

“We feel vindicated with this settlement, as we always felt the lawsuit was baseless,” said Glenn Woodcock, PSI president.  “We defended ourselves vigorously and are happy to report that our CSC-BF design does not infringe their patent.”

While the terms of the agreement remain confidential, PSI is free to continue to market, sell and support its current CSC-BF design around the globe, free from any claim by Nordson or Kreyenborg, PSI said in a prepared statement.
