Narrative Opinion Summary
The case involves a dispute between Scantibodies Clinical Laboratory, Inc. and Scantibodies Laboratory, Inc., and Nichols Institute Diagnostics, Inc., centering on allegations of patent infringement. Nichols accused Scantibodies of infringing its patent regarding antibodies and assays for detecting human parathyroid hormone (hPTH), while Scantibodies countered with claims of patent invalidity. The district court ruled in favor of Nichols, finding the patent valid and infringed. However, a stay on the injunction was partially granted, allowing Scantibodies to continue sales to existing patients. Scantibodies appealed, arguing the district court misinterpreted the patent claim, and the appellate court agreed there was a likely error, granting a stay pending appeal. Nichols attempted a cross-appeal to address several legal issues but was dismissed as unnecessary since the judgment remained unchanged. The court ruled in favor of Scantibodies' motion for a stay and dismissed Nichols' cross-appeal, with each party bearing its own costs.
