1Opinion of the Court
CLARK, Circuit Judge:
Invalidity for obviousness 1 is the broad subject of this patent appeal. A subsidiary issue is joined on the trial court’s application of the doctrine of file wrapper estoppel. The imitator who was successful in the court below cross-appealed from the court’s refusal to award it attorney’s fees. 2 Because we reverse the trial court’s determination of obviousness and its invocation of an estoppel against the patentees, the attorneys’ fee issue is eliminated; but the case must be remanded for an accounting.
