The Morrison Law Firm, which represented Robotic Vision Systems, Inc., appeals from the decision of the United States District Court for the Central District of California in which sanctions were ordered under Fed.R.Civ.P. 11. View Eng’g, Inc. v. Robotic Vision Sys., Inc., No. CV 95-1882 (C.D. Cal. June 26, 1996). Because the order containing the sanction was not final, and hence was not appealable, we' dismiss the appeal for lack of jurisdiction.
BACKGROUND
View Engineering, Inc. filed a declaratory judgment action against Robotic, alleging that one of Robotic’s patents was invalid and not infringed by View. Howard Stem, an employee of Robotic, believed that View infringed eight Robotic patents based upon his review of literature describing the accused View machines, his observation of machines at trade shows, and information received from View’s customers. Robotic thus counterclaimed for infringement of those eight patents. View apparently did not permit Robotic to inspect the accused machines pri- or to Robotic’s filing of its counterclaim.
Robotic repeatedly told View that when discovery was permitted, it would re-evaluate the infringement issue and withdraw any claim of infringement when information produced during discovery showed that any asserted patent was not infringed. During discovery, Robotic did review manuals for the accused machines and determined that they did not infringe two of the asserted patents. The charge of infringement with respect to those two patents was withdrawn. Shortly after View produced the manuals and other documents, it moved for sanctions.
The court granted View’s motion. It awarded sanctions against Morrison in the amount of seventy-five percent of View’s fees and costs for evaluating and defending against the counterclaims. The court arrived at that percentage based upon its finding that Robotic’s counterclaim for infringement of the eight patents included six patents for which Robotic failed to make a reasonable inquiry concerning whether infringement existed, as required by Rule 11. The court concluded that Robotic provided no factual basis for its counterclaim that View infringed the six patents. Rather, it found that in filing the counterclaim Robotic acted only upon the belief of Stern, one of its employees, not on a reasonable inquiry by counsel. The court found in effect that Morrison filed the counterclaim and then used discovery in order to determine if there was a factual basis for Robotic’s claim of infringement; the court concluded that this was a violation of Rule 11.
View filed an application for fees with the district court, but the court has not yet determined the amount of Morrison’s liability. Morrison now appeals the district court’s decision imposing Rule 11 sanctions.
DISCUSSION
Neither party in this case has questioned whether we have jurisdiction to hear this appeal. However, courts must always look to their jurisdiction, whether the parties raise the issue or not.
Under 28 U.S.C. § 1295(a)(1) (1994), our jurisdiction is limited to an appeal from a “final decision” of a district court.
*
The Supreme Court has stated that a final decision “generally is one which ends the litigation on the merits and leaves nothing for the court to do but execute the judgment.”
Catlin v. United States,
We have not previously determined whether a decision imposing Rule 11 sanctions is final and appealable before the amount of liability is decided. Several other circuits have decided that question and have held that a decision imposing Rule 11 sanctions is not final for purposes of appeal until the district court has decided the amount of liability.
See Cooper v. Salomon Bros. Inc., 1
F.3d 82, 85 (2d Cir.1993);
Southern Travel Club, Inc. v. Carnival Air Lines, Inc.,
Although it is our practice to follow precedent of the regional circuits on issues not unique to our areas of exclusive jurisdiction, we have adopted our own precedent on matters relating to our own appellate jurisdiction.
See Woodard v. Sage Prods., Inc.,
CONCLUSION
Because the district court has not yet determined the amount that Morrison is liable to pay as a sanction under Rule 11, the decision imposing sanctions was not final. *965 Therefore, we do not have jurisdiction over the present appeal and it is dismissed. When the district court enters an order determining the amount for which Morrison is liable, the case will be final for purposes of appeal.
DISMISSED.
Notes
None of the limited exceptions applies in this case. See, e.g., 28 U.S.C. § 1292(c) (1994).
