March 3, 2014 – A Western Washington district court judge granted summary judgment of non-infringement of US Patent No. 7,648,023 relating to an endoscope pre-cleaning kit owned by defendant Cygnus Medical LLC. Judge Robert S. Lasnik ruled that the endoscope pre-cleaning kits manufactured and sold by plaintiff Medtrica Solutions Ltd. do not infringe either literally or under the doctrine of equivalents, because the accused product does not contain the weakened line limitation or its equivalent. The kits are marketed under the names Appli-Kit and Revital-Ox and composed of a standup pouch containing an enzymatic detergent and a sponge.
