ND 3:05-cv-90

Declaratory judgment action (with infringement counterclaims) relating to 6,375,104 and 6,109,553, farm machinery processors for disintegrating baled crop material.  Judge Rodney Webb construed the key limitation “a manipulator mounted inside the container for driving crop material into the disintegrator” as means-plus-function language and limited it to the structure disclosed.  Patentee stipulated that accused products did not infringe the ‘104 patent as construed because they lacked the “manipulator” limitation.  Claims and counterclaims for (in)validity and those relating to the ‘553 patent were all dismissed without prejudice to set up the appeal.
