Narrative Opinion Summary
The case involves a patent infringement dispute between Louisville Bedding Company and Perfect Fit Industries, Inc. over the interpretation of United States Patent No. 5,249,322. Perfect Fit raised the defense of collateral estoppel, contending that the patent claims had been previously construed by Judge Simpson in a related case with Pillowtex Corporation and should not be re-litigated. The court applied the four-element test for issue preclusion, finding that the issues in question were identical, actually litigated, necessary to the prior judgment, and that Louisville Bedding had a full opportunity to litigate. Judge Simpson's interpretations, crucial to the prior judgment of non-infringement, were deemed preclusive. The court rejected Louisville Bedding's arguments against collateral estoppel, citing the finality of the prior settlement and the necessity for uniformity in patent claim construction as articulated in the Markman decision. Consequently, the court denied Louisville Bedding’s motion for partial summary judgment, affirming the preclusive effect of Judge Simpson’s prior claim interpretations and maintaining their applicability in the current litigation.
