Appeal from a judgment of the United States District Court for the Northern District of Texas, No. CA 3-83-1330-T. The district court determined that Gustafson, Inc.’s (Gustafson’s) United States Patent Nos. 3,383,924 (’924) and 4,443,587 (’587) were not invalid and were willfully infringed by Intersystems Industrial Products,
BACKGROUND
The ’924 and ’587 patents relate to devices that remove samples from pressurized pipes. On August 4, 1983 Gustafson sued Intersystems, alleging the latter’s model PS sampler infringed claims 1-11 of the ’924 patent. 1 On February 28, 1984, Gustafson’s ’587 patent issued and on June 7, 1984 Gustafson amended its complaint to assert that Intersystems’s models PTI and PDP samplers infringed claims 1, 7, 15 and 16 of that patent.
The district court made these findings and conclusions: (1) Intersystems’s model PS sampler infringed the ’924 patent; 2 (2) Intersystems’s models PDP and PTI samplers infringed the ’587 patent under the doctrine of equivalents; (3) The inventions defined in the asserted claims of the ’924 and ’587 patents would not have been obvious, 35 U.S.C. § 103 (1982), and were not anticipated, 35 U.S.C. § 102 (1982); (4) If Gustafson’s evidence were admissible, its lost profits would be $163,597; and (5) Gus-tafson “cannot recover damages because the Court cannot consider [Gustafson’s] evidence of lost profits.”
The district court having found that In-tersystems had willfully infringed and that this is an exceptional case, awarded Gustaf-son attorney fees. The relative findings read in their entirety:
14.Defendant Intersystems was aware of the existence of Plaintiff’s ’924 patent as of the date Plaintiff’s Original Complaint was filed.
15. Defendant Intersystems was aware of the existence of Plaintiff’s ’587 patent as of the date Plaintiff’s First Supplemental Complaint was Filed.
16. Defendant Intersystems took no action to ascertain whether the samplers it was producing would infringe on Plaintiff’s samplers patents.
17. Defendant designed, engineered and manufactured its Model PS sampler to compete with the Model R Gustafson sampler.
18. This is an exceptional case pursuant to 35 U.S.C. § 285.
ISSUE
Whether the district court clearly erred in finding Intersystems’s infringement willful.
OPINION
Introduction
The parties attempt to retry their cases on appeal. Except for the arguments on willfulness, none even remotely approaches a showing of reversible error. Hence a detailed discussion of those arguments would serve no useful purpose and would unduly lengthen this opinion.
It is sufficient to state that we find no reversible error in the district court’s: (1) finding that Intersystems’s model PTI and model PDP samplers infringed claims 1, 7, 15, and 16 of the ’587 patent under the doctrine of equivalents; (2) holding that those claims had not been shown to be invalid; (3) excluding plaintiff’s exhibit 29 as inadmissible hearsay,

F.2d 200, 202 (5th Cir.1976) (report of third-party statement inadmissible); (4) awarding no damages to Gustafson because none were proven,

Willful Infringement
Whether infringement is willful is a question of fact, findings on which are reviewable under the clearly erroneous standard of Rule 52(a), Fed.R.Civ.P.
CPG Prods. Corp. v. Pegasus Luggage, Inc.,
The district court found that Inter-systems “took no action to ascertain whether the samplers it was producing would infringe.” However, the district court also found that Intersystems was aware of each of the patents only “as of” the date on which suit was filed on each. Gustafson does not challenge that finding, but argues, from its version of bits and pieces of the record, that the court might have found earlier awareness of the patents. Gustafson forgets that we do not sit to find facts or to decide hypotheticals.
In a sequence of cases involving claims of willful infringement, this court has evolved a jurisprudence applicable to situations in which a product found an infringement at trial had been manufactured before the patent issued. In
State Industries, Inc. v. A.O. Smith Corp.,
It is obvious that a party cannot be held liable for “infringement”, and thus not for “willful” infringement, of a
nonexistent
patent, i.e., no damages are payable on products manufactured and sold before the patent issued. Whether an act is “willful” is by definition a question of the actor’s
intent,
the answer to which
In our patent system, patent applications are secret, and patentees are authorized to sue “innocent” manufacturers immediately after their patents issue and without warning. To hold such patentees entitled to increased damages or attorney fees on the ground of willful infringement, however, would be to reward use of the patent system as a form of ambush.
Because nothing of record indicates that Intersystems knowingly acted in disregard of Gustafson’s patent rights, the finding of willful infringement cannot stand.
Attorney Fees
At oral argument, Gustafson admitted that the award of attorney fees was based solely on the finding of Intersystems’s willful infringement. Because that finding is clearly erroneous, no basis exists for designating this an “exceptional” case or for granting attorney fees.

Notes
. Gustafson also asserted infringement of its United States Patent No. 4,389,906. The district court held that patent invalid in a November 12, 1986 partial summary judgment not challenged by Gustafson in connection with this appeal.
. The '924 patent expired on May 21, 1985. Hence Intersystems’s challenge to the injunction relates only to the '587 patent.
