Caliper won its case by convincing a US court that patent lawyer Dr. Bertrain Rowland represented both Aclara and Caliper during overlapping periods, that he misused Caliper’s trade secrets, and that Aclara should be liable for Dr. Rowland's actions. Alcara claimed that it did not know that Dr. Rowland was also acting for its competitor.
The companies also have two outstanding patent disputes.
