JAMESBURY CORP., Plaintiff-Appellant, v. LITTON INDUSTRIAL PRODUCTS, INC., Defendant-Appellee.
No. 87-1106
United States Court of Appeals, Federal Circuit
Feb. 10, 1988
Donald R. Dunner, of Finnegan, Henderson, Farabow, Garrett & Dunner, Washington, D.C., argued for defendant-appellee.
Before SMITH, NIES, and ARCHER, Circuit Judges.
EDWARD S. SMITH, Circuit Judge.
Jamesbury Corp. (Jamesbury) sued Litton Industrial Products, Inc. (Litton), for infringement of its patent, United States patent No. 2,945,666 (the ‘666 patent). The United States District Court for the District of Connecticut granted summary judgment in favor of Litton on the issues of laches and estoppel.1 We affirm.
Issues
(1) Whether the district court erred in holding that the law of the case doctrine did not preclude it from reconsidering the initial denial of summary judgment in light of the subsequent history of the case.
(2) Whether the district court erred in holding that Jamesbury was barred by laches from recovering damages which occurred prior to the filing of its complaint.
(3) Whether the district court erred in holding that Jamesbury‘s suit for infringement was barred by equitable estoppel.
I. Background
(A) Litigation Involving the ‘666 Patent.
The ‘666 patent, which relates to the manufacture of ball valves, was issued on July 19, 1960, and assigned to Jamesbury. The ‘666 patent has been the subject of numerous suits since 1962. First, Jamesbury sued Pacific Valves, Inc. (Pacific Valves), for infringement in New Jersey in February 1962. Then, on July 10, 1963, Jamesbury filed suit against the United States in the Court of Claims for infringement, alleging that “the defendant has used numerous ball valves embodying the invention manufactured by Electric Boat Division, General Dynamics Corp., Groton, Connecticut, by Pacific Valves, Inc., Long Beach, California, and others.” On December 16, 1963, in response to a Government request to identify the “others,” Jamesbury named 10 companies, including Worcester Valve Co. (Worcester Valve) and Litton‘s predecessor in interest, UTD Corp., Contromatics Division (Contromatics).2
The Pacific Valves litigation was settled, and the case was dismissed in April 1965. In May 1965, Jamesbury filed suit against Worcester Valve in Massachusetts, and against the Lunkenheimer Co. in Ohio. The Court of Claims action was amended in June 1965 to name Worcester Valve specifically as an infringer. On May 16, 1967, Commissioner Lane issued a recommended decision in the Court of Claims case finding that claims 7 and 8 of the patent were valid and infringed by the Government‘s use of valves made by Worcester Valve and Electric Boat Division. Jamesbury also filed a declaratory judgment action in Texas against KTM Industries on October 30, 1970.3
On September 20, 1974, Trial Judge Colaianni issued a supplemental opinion in the Court of Claims case concluding that claims 7 and 8 of the patent were valid and infringed. The Court of Claims affirmed and adopted the opinions of Commissioner Lane and Judge Colaianni on July 11, 1975.5 In February 1980, Judge Colaianni filed a recommended decision assessing damages of $10.2 million. Of the total, 20 percent was attributable to ball valves manufactured by Contromatics.6 The case was later settled for $8 million.
(B) The Litton Litigation.
Jamesbury wrote to the president of UTD Corp. on October 12, 1967, advising him that, in the opinion of Jamesbury‘s Engineering Department, Contromatics’ ball valves infringed the ‘666 patent and that Jamesbury was prepared to discuss a licensing agreement. On October 31, 1967, UTD responded that its patent attorneys had studied the patent and had concluded that there was no infringement. UTD suggested a meeting with Jamesbury to discuss the issue. Jamesbury accepted UTD‘s invitation in a letter which included a copy of Commissioner Lane‘s ruling in the Court of Claims action. The letter noted that the patent had been held valid and infringed by the Government which “purchases its valves from various suppliers.” It closed with a statement that Jamesbury‘s patent attorney was available to discuss its position with UTD‘s attorneys. A meeting was held in December, but the issue was not resolved. On January 5, 1968, Jamesbury wrote to UTD that
[w]e have reported your position to our attorneys and the subject is under careful consideration.
Jamesbury had no further contact with UTD until this suit was filed on February 10, 1976.
Litton moved for dismissal based on the defenses of laches and equitable estoppel. Judge Blumenfeld, the district court judge originally assigned to this case, treated it as a motion for summary judgment since both parties relied on affidavits and other matters outside the pleadings. The motion was denied because the court determined that there were triable issues of fact concerning both defenses.7 Litton then moved for summary judgment on the ground that claims 7 and 8 were invalid for overclaiming. Judge Blumenfeld granted this motion, but the Second Circuit reversed because the test used by the district court to determine the patentability of a combination having a novel element was too narrow.8
On remand, Jamesbury requested that Judge Blumenfeld recuse himself which he did, and the case was reassigned to Judge Dorsey. Litton moved for summary judgment on the issues of laches, estoppel, and prejudgment interest. Judge Dorsey granted the motion on the defenses of laches and estoppel. Jamesbury appeals the November 5, 1986, grant of summary judgment by the district court on the laches and estoppel defenses.
II. Summary Judgment
Summary judgment, in a patent case as in any other type of case, is appropriate when there are no genuine issues of material fact and the movant is entitled to judgment as a matter of law.11 The district court must view the evidence in the light most favorable to the nonmoving party, and any doubt as to the existence of issues of material fact must be resolved in favor of the party opposing the motion.12 The movant bears the burden of demonstrating the absence of any genuine issue of material fact.13 However, when the movant has supported his motion as provided by
In reviewing the grant of summary judgment, we must determine whether the district court erred in concluding that there were no genuine issues of fact, and that Litton was entitled to judgment as a matter of law.16 In support of its motion for summary judgment, Litton submitted a list of
Jamesbury claims the district court erroneously assumed that (1) there was infringement by Contromatics beginning in 1963 and (2) Jamesbury was aware of it because in 1963 Jamesbury asserted that valves made by Contromatics for the Government infringed Jamesbury‘s patent. Jamesbury argues that it could not have charged Contromatics with infringement in 1963 because, by virtue of
[W]here a non-movant has failed to establish specific fact issues in response to a Rule 56 motion, he cannot later be heard to attack the judgment on the basis of matters that, had he but raised them earlier, might have precluded its grant. * * *
Having determined that the district court did not err in concluding there were no genuine issues of material fact left for trial, we must now decide if the court erred in holding that Litton was entitled to judgment as a matter of law.
III. The Law of the Case Doctrine
Jamesbury contends the law of the case on the issue of laches was established by the denial of Litton‘s original motion for summary judgment, and the denial of its motion for a directed verdict and failure to cross-appeal therefrom. According to Jamesbury, the law of the case is that laches is inappropriate for summary judgment, and the district court erred in departing from the law of the case in granting Litton‘s current motion for summary judgment.
The district court rejected Jamesbury‘s law of the case argument because neither the denial of the motion for directed verdict nor the original summary judgment motion had conclusively addressed Litton‘s arguments. Jamesbury argues that the district court erred because it did not consider the “crucial fact” that Litton failed to cross-appeal the denial of the directed verdict. But Litton‘s failure to cross-appeal the denial of its motion for a directed verdict on laches has no effect on the law of the case for the simple reason that Litton could not have cross-appealed that ruling. Only judgments can be appealed,24 and the judgment in this case was of the invalidity of the patent. No judgment was entered on the laches defense, so Litton could not have cross-appealed the denial of its motion for directed verdict on that issue.25 In addition, only a party adversely affected by a judgment can appeal,26 and Litton was not adversely affected by the invalidity judgment. Therefore, it is clear that Litton could not have cross-appealed the denial of its motion for directed verdict on laches, and its failure to do so has no effect on the law of the case.
As the district court noted, there is a judicial preference in favor of granting a judgment n.o.v. over a directed verdict. The rationale behind the preference is the effect of an appellate court‘s reversal of a judgment in each situation. With a directed verdict, the entire case must be retried if the judgment is overturned, while with a judgment n.o.v., the jury verdict can be entered as the judgment should the appellate court reverse. Thus, it is in the interest of efficient judicial administration for a court to withhold ruling on a motion for directed verdict in favor of deciding a motion for judgment n.o.v.27 Therefore, the district court was correct in holding that the denial of Litton‘s motion for directed verdict on laches did not conclusively determine that issue.
[O]n a renewed motion for summary judgment before a second judge, the district court must balance the need for finality against the forcefulness of any new evidence and the demands of justice. With respect to a non-appealable denial of summary judgment, the law of the case is not a limit on the court‘s jurisdiction, but a rule of practice which may be departed from in the sound discretion of the district court. The first judge always has the power to change a ruling; further reflection may allow a better informed ruling in accordance with the conscience of the court. A fortiori, if the first judge can change his mind after denying summary judgment, and change his ruling, a second judge should have and does have the power to do so as well.
The district court concluded that the long history of this case, which includes a full jury trial, required it to consider events subsequent to the original denial. Jamesbury‘s only response to this controlling case law was to argue that the court‘s balancing was wrong because it considered the delay from 1963 to 1967. Jamesbury argues that this was not really a delay because the Government, not Contromatics, was infringing during that time, and it was presumptively reasonable because it was less than 6 years. As was discussed previously, the court did not err in considering the 1963 to 1967 period.
This case was before the district court for 9 years, and much is known now that was not known at the time of the original motion. A full trial has been held, and Jamesbury had the opportunity to present all of the evidence it had on the laches defense. The only reason this issue was not resolved at trial is the phrasing of the jury instructions. Therefore, the district court did not err in considering all of the evidence in the record in deciding the second summary judgment motion.
IV. Laches
Laches is an equitable defense which depends on consideration of all of the facts in the particular case. It is a matter within the trial court‘s discretion and will not be set aside absent a showing of abuse of discretion.31 As applied in patent infringement cases, it bars recovery of damages for any infringement occurring prior to the filing of the suit. In order to
Both Jamesbury and Litton agree that the presumption applies in this case, but they disagree as to the length of the delay. Jamesbury claims the delay is only 8 years, from the time it contacted Contromatics about infringement in 1967-68 until it filed suit in 1976. Litton, on the other hand, argues that the delay is 12 years, running from the time Jamesbury named Contromatics as producing infringing valves for the Government in the Court of Claims action in 1963 until it filed suit. In determining the length of delay for laches, a court must look at the time the patentee knew, or in the exercise of reasonable diligence should have known, of the alleged infringing activity.34 Here, Jamesbury either knew, or should have known, of Contromatics’ infringement in 1963 since it named Contromatics in the Court of Claims case as an infringer at that time. Therefore, the district court correctly considered the length of Jamesbury‘s delay for purposes of laches to be 12 years.
The burden was thus on Jamesbury to excuse its delay. Jamesbury alleges that its involvement in other litigation constitutes an adequate excuse for its delay in suing Litton. Many courts have recognized that involvement in other enforcement litigation may excuse a patentee‘s delay in suing an alleged infringer.35 In Leinoff v. Louis Milona & Sons, Inc.,36 this court suggested that litigation involving the patent might be an adequate excuse for delay in filing suit in the proper circumstances.
It may well be, though we do not now so hold, that suit on one or more test cases, instead of suing every known infringer, was reasonable in light of the high cost of patent litigation and the comparatively moderate amounts recoverable by our patentee per infringer, and if the infringers understood there was no intent to condone their infringements. * * *
We hold that a patentee‘s involvement in litigation against one or more infringers may excuse delay in enforcing the patent against another infringer if the infringer understands that the patentee is not acquiescing in the infringement.37
Although courts have uniformly recognized that involvement in other litigation may excuse delay in filing suit against alleged infringers, they have been less consistent regarding the circumstances under which it may be appropriately invoked. Several early cases held that merely filing suit against one infringer was sufficient to excuse delay in filing against another infringer.38 More recent cases have rejected
If the patentee does act to enforce his patent and the alleged infringer is informed of it, he cannot reasonably expect his business will remain unmolested. However, if the alleged infringer does not know about the patentee‘s actions to enforce the patent, the belief that he will be left alone is still reasonable. The alleged infringer cannot know the patentee‘s intentions unless the patentee tells him. Notice of the other litigation informs the alleged infringer that the patentee does not intend to leave him alone * * *
We agree that, in order to excuse delay based on other litigation, the patentee must give notice to the alleged infringer of the existence of the other litigation and of an intent to enforce its rights against the infringer at the conclusion of the other litigation.41
In this case, there is no question that Jamesbury notified Contromatics of the Court of Claims litigation, so it has met the first part of the test. It cannot meet the second part, however. Jamesbury accused Contromatics of infringement in the October 12, 1967, letter and offered to license the patent. Contromatics responded by denying infringement and suggested a meeting to discuss the issue. The meeting did not settle the question, and Jamesbury‘s final contact with Contromatics, prior to filing suit 8 years later, indicated only that it had submitted Contromatics’ position to its attorneys and the subject was under consideration. Jamesbury never clearly indicated that it intended to enforce its rights against Contromatics after the Court of Claims litigation ended. Given the equivocal nature of Jamesbury‘s contacts with Contromatics, Jamesbury failed to give adequate notice to Contromatics, as concluded by the district court.
Litton argues to this court, as it did to the district court, that Jamesbury‘s “pattern of litigation” suggested that it did not intend to sue Litton. Litton contends that Jamesbury promptly sued other infringers during the pendency of the Court of Claims litigation, and, since Jamesbury did not sue it during the Court of Claims litigation, it reasonably concluded that Jamesbury did not intend to sue it. The district court properly rejected this argument. As the district court noted, the rationale for the other litigation excuse, that the high cost of patent litigation and the comparatively small amounts recoverable from each infringer justify not requiring the patent owner to sue all infringers at the same time, would be defeated by accepting Litton‘s position.
The district court did not abuse its discretion in granting summary judgment to Litton on the issue of laches.
V. Estoppel
Like laches, estoppel depends on the facts of the particular case and is a matter within the court‘s discretion which will not be set aside absent a showing of abuse of discretion.42 However, although the defenses of laches and estoppel are frequently raised together, they have different requirements and different effects on the rights of the patent owner. In order to prove estoppel, the alleged infringer must show (1) unreasonable and inexcusable delay in filing suit, (2) prejudice to the infringer, (3) affirmative conduct by the patentee inducing the belief that it abandoned
The fundamental differences between laches and estoppel suggest that the presumptions which apply to laches should not apply to estoppel. Estoppel requires representations or conduct by the patentee from which the alleged infringer could reasonably infer that the patentee had abandoned his claim. “For silence to work an estoppel, some evidence must exist to justify an inference that the silence was sufficiently misleading to amount to ‘bad faith.‘”45 The silence must be sufficient “to induce the alleged infringer to reasonably infer that the patentee has abandoned his patent claims” against the alleged infringer.46
The court in Naxon Telesign Corp. v. Bunker Ramo Corp.,47 explained why the burden of proving prejudice should not be shifted from the infringer.
First, the consequence of a finding of estoppel completely bars a plaintiff from asserting its rights. Moreover, the nature of estoppel is based on a misleading act of the plaintiff and detrimental reliance by the defendant. [Footnote omitted.] * * * Therefore, in light of the severity of the result of a finding of estoppel, a court should not lightly presume injury to the party raising the defense. * * *
Secondly, many of the cases which the defendants and the district court relied on regarding the shifting of the burden of proof are either cases dealing with laches [footnote omitted] or cases which found estoppel, but did not shift the burden in doing so. While there is broad language in those cases which arguably could be applied in the estoppel context, it is better to limit such decisions to the facts presented in each case. * * *
We agree with the reasoning of the Seventh Circuit and hold that the burden of proof in an estoppel defense cannot be shifted from the alleged infringer.
In this case, the district court relied on the finding of laches to establish the first two elements of estoppel. However, in its discussion of laches, the court specifically dealt with both unreasonable delay and prejudice absent the presumptions. First, we note that the period of delay for estoppel is not necessarily the same as the delay for laches. With estoppel, delay is measured from the time of the misrepresentation or the beginning of the misleading silence. Here, the delay began when Jamesbury notified Contromatics that it had reported Contromatics’ position to its attorneys and was considering the matter carefully. The delay by Jamesbury from the time it sent the letter to Contromatics until it filed suit was unreasonable.
The district court also considered the question of material prejudice to Contromatics absent the presumption. The court noted the testimony of Litton‘s president that had he been president of Contromatics in 1967-68 and known of the allegation of infringement by Jamesbury, he would have sold the corporation rather than make continued capital investments. The court concluded that those investments were uncontroverted evidence of material prejudice. We agree that the capital investments made by Contromatics constitute material prejudice.48
The next element of estoppel is a misrepresentation or misleading silence by the
The final element of estoppel is detrimental reliance by the infringer. The district court found detrimental reliance based on the investments in the manufacture of ball valves by Contromatics, and Jamesbury‘s failure to submit any evidence in rebuttal on this issue. Jamesbury argues that Litton cannot satisfy this element because the notice was given to Contromatics, and Litton cannot rely on the notice to Contromatics. As the district court noted, Jamesbury‘s position is inconsistent. If Litton cannot rely on the notice to Contromatics, then it is clear that Litton had no notice at all, and Jamesbury‘s claim would be defeated by both laches and estoppel. The district court properly held Litton liable for the knowledge of Contromatics of the allegation of infringement because Litton was the successor in interest to Contromatics.49 The corollary to that holding is that Litton is entitled to rely on the lack of communication to Contromatics, as well as to itself, following the letter.
Jamesbury also contends that the district court erred in stating that it had produced no evidence in support of its claim that Litton relied on a noninfringement opinion from its counsel rather than on Jamesbury‘s inaction. Jamesbury argues that it produced evidence at trial of the existence of the noninfringement opinion from which an inference can be drawn that Contromatics relied on that opinion rather than any inaction by Jamesbury. Jamesbury, in the motion for summary judgment which is the subject of this appeal, did not assert that this was a material question of fact before the district court and cannot raise it here.50
Therefore, the district court did not abuse its discretion in granting summary judgment on the issue of estoppel.
VI. Conclusion
The district court properly determined that the law of the case did not prevent it from reconsidering Litton‘s motion for summary judgment. The court also correctly held that Litton was entitled to summary judgment on the defenses of laches and estoppel. We affirm the judgment of the United States District Court for the District of Connecticut.
AFFIRMED.
NIES, Circuit Judge, concurring-in-part.
I join Judge Smith‘s opinion except Part V on estoppel in which I concur in result. We are reviewing a summary judgment grant. Therefore, it is only necessary here to answer Jamesbury‘s single argument, namely, that there is a disputed fact issue with respect to Litton‘s detrimental reliance. On that point, I agree that there is no presumption arising from a six-year (or even longer) delay that the alleged infringer detrimentally relied on a patentee‘s acts. I also agree that the infringer here affirmatively established the detrimental reliance element of estoppel and that there is no genuine factual dispute on the matter.
I join Judge Archer‘s opinion, which, accordingly, becomes the majority opinion on the issue of estoppel.
ARCHER, Circuit Judge, concurring-in-part.
I join the majority opinion except Part V on estoppel in which I concur in the result.
I also agree with the concurrence-in-part of Judge Nies.
Notes
“Does the ball valve construction shown and described in the Saunders British patent or any other prior art differ in any significant particulars from the ball valve defined by the express language of claims 7 and 8 of the Freeman patent?
“As to claim 7 Yes ____ No X
“As to claim 8 Yes ____ No X
“If you answer ‘No’ as to both claim 7 and claim 8, do not answer any further questions.”
The remaining questions were directed to infringement, laches, estoppel and damages. In accordance with the above direction, the jury answered only interrogatory No. 1.“Whenever an invention described in and covered by a patent of the United States is used or manufactured by or for the United States without license of the owner thereof or lawful right to use or manufacture the same, the owner‘s remedy shall be by action against the United States in the United States Claims Court for the recovery of his reasonable and entire compensation for such use and manufacture.”
“Jamesbury became convinced that Contromatics was infringing the patent-in-suit no later than December of 1963. On July 10, 1963, Jamesbury filed suit against the U.S. Government in the Court of Claims for infringement of the patent-in-suit, alleging in part:
” ‘The defendant ... has used numerous ball valves embodying the invention manufactured by Electric Boat Division, General Dynamics Corp., Groton, Connecticut, by Pacific Valves, Inc., Long Beach, California, and others.’
(emphasis added). In response to a request by the Government to identify ‘the others’ mentioned in the complaint, on December 16, 1963 Jamesbury identified ten companies, including Contromatics and Worcester Valve.” ****
