as against him. We conclude that such fees and costs were improperly assessed against the appellant under 35 U.S.C. § 285, and remand the case to the district court for more explicit findings with respect to any fees and costs which may appropriately be assessed against the appellant pursuant to Rule 37, Fed. R.Civ.P.
Briefly stated the background of the controversy is as follows: In 1969 Frank J. and Marie Kaehni, owners of the patent in suit, filed infringement actions against Diffraction Company, manufacturer of the accused devices, and eight other parties, including the appellees here, who allegedly marketed the devices and were thereby exposed to derivative liability in the event infringement was established. The appellant Stillman represented the Kaehnis in all of these lawsuits. The Panel on Multi-District Litigation consolidated the cases and referred them to the District of Maryland. Thereafter, the parties agreed that the suit against Diffraction should proceed to trial on the issue of infringement, postponing for separate trials the contingent question of liability and damages against the other defendants. Prior to trial of the case, Diffraction and the appellees filed motions to dismiss which were denied. In the order of denial, the court stated that in the event there should be a finding of non-infringement it would entertain motions from the defendants for costs and attorney fees under 35 U.S.C. § 285. At the conclusion of a lengthy trial, the court exonerated Diffraction on all charges of infringement.2 The court further found that the allegations of infringement were frivolous and had been asserted without reasonable care or sufficient justification. Under these circumstances the court concluded that the case was “exceptional” within the meaning of Section 285 and awarded Diffraction reasonable attorney fees. In doing so, however, the court stated that “it must distinguish between overzealous clients and overzealous counsel, for § 285 is directed only at the former.”3 Accordingly, the award to Diffraction was charged only against the Kaehnis and not against their attorney, Stillman.
After Diffraction had prevailed on the merits, the defendant appellees renewed their motions to dismiss and recovery of attorney fees and costs. Following a hearing on the motions the court entered judgments jointly and severally against the Kaehnis and Stillman. Although stated specifically only in the order relative to the defendant S. S. Kresge Company, the awards in all of these cases were apparently based on both 35 U.S.C. § 285 and Rule 37.
The record in Diffraction as well as these appeals provides ample support for the district court’s finding that these were “exceptional cases” justifying an award under Section 285. The purpose of the statute is to permit the court to award fees in an extraordinary case to prevent gross injustice, and the cases before us, obviously instituted for purposes of harassment, are precisely the type of litigation calling for the imposition of the statutory sanctions. There is equal support in the record for the district court’s finding that Stillman, as attorney for the plaintiffs, was guilty of dilatory and vexatious conduct which unduly prolonged the course of this litigation. Despite that fact, however, we think the assessment against him under Section 285 was improper. In our opinion the sanctions are directed to the parties, and it is not the purpose of the statute to discipline uncooperative or overzealous counsel.4 This, of course, was the position of the district judge in the Diffraction case. While we can appreciate the reaction of the court to Still-
