In this case the trial court entered a final judgment on a jury verdict awarding damages to Micro Chemical, Inc. The defendants, Lextron, Inc. and Turnkey Computer Systems, Inc. (collectively, “the defendants”), appeal, challenging the district court’s understanding of Rule 702 of the Federal Rules of Evidence and of the Supreme Court’s decision in
Daubert v. Merrell Dow Pharmaceuticals, Inc.,
509 U.S.
*1389
579,
BACKGROUND
Micro Chemical and Lextron are direct competitors in the business of providing goods and services to cattle feedlots. Among the goods they supply to their customers are drugs and equipment used to treat illnesses afflicting cattle, referred to by the parties in this litigation as “animal health products.” They also offer their feedlot customers computerized medical records systems for tracking health histories and medical treatments of livestock. Micro Chemical’s medical records system is the commercial embodiment of the invention in its U.S. Patent No. 5,315,-505 (“the '505 patent”), the patent at issue in this case.
The evidence indicates that Micro Chemical provides its computer systems essentially free of charge to feedlots in an effort to promote sales of its animal health products. Lextron also places its computer systems in feedlots for free or at a substantial loss. The record contains evidence that Lextron’s goal also is to generate sales of its animal health products, although Lextron disputes that on appeal.
Turnkey supplies accounting system software to cattle feedlots. Among the add-on software modules offered by Turnkey is an animal records module, which tracks health and treatment histories of livestock. Turnkey has also created interfaces between its accounting system and other companies’ medical records systems. The record includes evidence that Turnkey underpriced its animal records module and that sales of the animal records module support sales of its accounting system.
When the '505 patent issued in 1994, Micro Chemical filed a patent infringement suit against Lextron and Turnkey. In the course of that litigation, the defendants stipulated that their original systems infringed the '505 patent. Both defendants then modified their systems to remove the feature they believed was necessary to a finding of infringement; this feature related to a displayed warning if an animal was scheduled for shipment to a slaughterhouse before the end of the withdrawal period for all drugs administered to the animal.
An issue remained as to whether Lex-tron’s modified system infringed. The district court conducted a Markman hearing directed to a disputed claim limitation relating to a drug withdrawal calculation. After the court issued an order adopting Micro Chemical’s claim construction, Lex-tron stipulated that its modified system infringed under that construction. The district court entered a stipulated judgment, and an earlier appeal to this court followed. On. appeal this court disagreed with the district court’s claim construction, vacated the judgment, and remanded for further proceedings.
Micro Chem., Inc. v. Lextron, Inc.,
No. 97-1589,
In response, Micro Chemical amended its complaint to limit its infringement allegations to the defendants’ unmodified systems. The only issue thus left for trial was the amount of damages from the date *1390 the patent issued to the dates in 1997 when the defendants modified their systems.
Prior to the trial on damages, the defendants filed motions in limine to preclude certain testimony by Micro Chemical’s damages expert, Edward Fiorito. First, the defendants sought to prevent Fiorito from testifying that the defendants’ 1997 modified systems could not be considered non-infringing alternatives for purposes of determining the amount of damages. The district court denied that motion without comment. The defendants also filed a motion to preclude Fiorito from testifying that a reasonable royalty for Lextron’s infringing computer systems would be three percent of its revenues from sales of animal health products, as Fiorito had stated in his expert report. The trial court ruled that Micro Chemical could not recover a royalty on the animal health products themselves but could show that sales of animal health products were relevant to a reasonable royalty determination because Micro Chemical alleged that the defendants used their infringing systems as loss leaders to promote animal health product sales. The defendants further sought to preclude Fiorito from testifying at all on the grounds that his testimony would not satisfy the requirements for expert testimony set out in Rule 702 of the Federal Rules of Evidence and the Supreme Court’s decision in Daubert. The district court reserved ruling on the defendants’ Daubert motion.
At trial, Fiorito testified that a reasonable royalty for the defendants’ infringing systems based upon a hypothetical negotiation between the parties at the time infringement began would be $400 per month per system. To support this figure, Fiorito analyzed the relevant factors set out in
Georgia-Pacific Corp. v. United States Plywood Corp.,
The defendants’ damages expert, Walter Bratic, took the position that there was no connection between installation of the defendants’ infringing systems and sales of the defendants’ other products. He also opined that the value of the patented invention was negligible. Bratic testified that a reasonable royalty would be one percent of the defendants’ imputed revenues, i.e., the revenues if the defendants had sold their infringing systems for full retail price. This would result in $12,717 in damages from Lextron and $735 from Turnkey.
The jury returned a verdict against Lex-tron in the amount of $1,015,180 and against Turnkey in the amount of $72,800. The defendants filed post-trial motions for judgment as a matter of law (JMOL), or in the alternative, for a new trial. The defendants now appeal the district court’s decision not to exclude Fiorito’s testimony, and the denial of those motions.
DISCUSSION
I.
Whether proffered evidence should be admitted in a trial is a procedur
*1391
al issue not unique to patent law, and therefore we review the district court’s decision whether to admit expert testimony under the law of the regional circuit, here the Fifth Circuit.
See Bose Corp. v. JBL, Inc.,
A.
As a preliminary matter, we reject Micro Chemical’s contention that the defendants waived their right to challenge on appeal the admission of Fiorito’s testimony. Under the 2000 amendment to Rule 103 of the Federal Rules of Evidence, “[o]nee the court makes a definitive ruling on the record admitting or excluding evidence,
either at or before trial,
a party need not renew an objection or offer of proof to preserve a claim of error for appeal.” Fed.R.Evid. 103(a) (emphasis added);
see also Mathis v. Exxon Corp.,
Here, the district court made definitive rulings either before or at trial on all of the defendants’ objections to Fiorito’s testimony. Before trial, the district court denied the defendants’ motion in limine objecting to Fiorito’s proposed testimony that defendants’ modified systems were not relevant to the determination of a reasonable royalty. Regarding the defendants’ motion in limine objecting to the use of animal health product sales in the damages determination, the district court ruled before trial that sales of animal health products could not serve as the royalty base but could otherwise be relevant to a reasonable royalty calculation, and then reiterated its ruling in response to the defendants’ objection during trial. Finally, the district court reserved ruling prior to trial on the defendants’ motion in limine to exclude Fiorito’s testimony in toto on Daubert grounds. At the conclusion of Fiorito’s testimony, however, the defendants renewed their objection on Daubert grounds, which the district court clearly overruled at that time. Thus in each of these situations the defendants’ right to appeal the admission of Fiorito’s testimony was preserved.
B.
The landmark case of
Daubert v. Merrell Dow Pharmaceuticals, Inc.,
In 2000, Rule 702 was amended in response to Daubert and cases applying it, including Kumho Tire. That rule now pro *1392 vides that an expert witness with “scientific, technical, or other specialized knowledge” may testify in the form of an opinion “if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.” Fed.R.Evid. 702.
The defendants contend that the district court in this ease failed to perform its gatekeeping duties when it allowed Fiorito to testify. Specifically, the defendants argue that Fiorito based his opinion on inaccurate facts because he relied on the statements of others and did not undertake an independent investigation of the feedlot industry or personally review the parties’ financial records. The defendants further argue that Fiorito misapplied the Georgia-Pacific factors and that he repeatedly misstated and distorted the law regarding consideration of non-infringing alternatives and convoyed or derivative sales in determining reasonable royalty damages. We address each of these issues in turn.
First, we disagree with the defendants’ assertion that Fiorito’s testimony did not satisfy subpart (1) of Rule 702, which provides that expert testimony must be “based upon sufficient facts or data.” Defendants confuse the requirement for sufficient facts and data with the necessity for a reliable foundation in principles and method, and end up complaining that Fiorito’s testimony was not based on “reliable facts.” The parties disputed many of the facts relevant in determining a reasonable royalty, the foremost being whether the defendants’ modified systems would have been available at the time of a hypothetical royalty negotiation and whether the defendants promoted sales of their other products by distributing their infringing systems to feedlots free of charge or at a substantial loss. When, as here, the parties’ experts rely on conflicting sets of facts, it is not the role of the trial court to evaluate the correctness of facts underlying one expert’s testimony. We find the Advisory Committee note to Rule 702 instructive in this regard:
When facts are in dispute, experts sometimes reach different conclusions based on competing versions of the facts. The emphasis in the amendment on “sufficient facts or data” is not intended to authorize a trial court to exclude an expert’s testimony on the ground that the court believes one version of the facts and not the other.
See also Pipitone v. Biomatrix, Inc.,
In this case, the trial court properly did not rule inadmissible Fiorito’s damages testimony simply because it was based on Micro Chemical’s version of the contested facts. The defendants had ample opportunity to rebut Fiorito’s damages theory during cross-examination. They also presented their competing theory through the testimony of their own expert witness, who based his opinion testimony on the defendants’ version of the disputed facts. Under these circumstances, the district court did not abuse its discretion in allowing Fiorito to testify.
*1393
Furthermore, we cannot say that Fiorito’s testimony was the product of an unreliable methodology. This court has “endorsed the conceptual framework of a hypothetical negotiation between patentee and infringer as a means for determining a reasonable royalty.”
Interactive Pictures Corp. v. Infinite Pictures, Inc.,
The defendants contend that the district court should not have permitted Fiorito to consider sales of the defendants’ other products in arriving at a reasonable royalty. Before trial, the district court ruled that Micro Chemical could not include sales of non-patented items in the royalty base but could demonstrate that those sales were relevant in determining a reasonable royalty. That ruling is consistent with one of the
Georgiar-Pacific
factors— “[t]he effect of selling the patented specialty in promoting sales of other products of the [infringer].”
The defendants also argue that Fiorito’s testimony regarding the availability of non-infringing alternatives at the time of infringement was contrary to our decision in
Grain Processing Corp. v. American Maize-Products Co.,
This case involves reasonable royalty damages, not lost profits. This court has not had occasion to address whether the holding of
Grain Processing
has applicability in the reasonable royalty context. We need not decide that issue here, because in any event Fiorito’s testimony was not inconsistent with the rule of
Grain Processing.
In discussing one of the
Georgiar-Pacific
factors — “[t]he utility and advantages of the patent property over the old modes or devices, if any, that had been used for working out similar results,”
We have considered and are not persuaded by the defendants’ other arguments regarding the admissibility of Fiori-to’s testimony, including the defendants’ contention that the district court erred by refusing to give corrective instructions to the jury. Fiorito’s testimony did not run afoul of Rule 702, and the district court did not abuse its discretion in admitting it.
II.
The amount of damages based on a reasonable royalty is an issue of fact.
Unisplay,
This case is a classic example of competing experts. Each side had the opportunity to present its damages theory. Each party’s expert supported his reasonable royalty determination with an analysis of relevant factors based on his client’s view of the disputed facts. The outcome of the case depended to a large extent upon which predicate facts the jury believed, and then on which expert’s analysis they believed. Upon reviewing the record, we cannot say that Micro Chemical’s damages theory and the jury’s ultimate damages award were unsupported by substantial evidence. 1 The defendants may not like the jury verdict, but it was the result of a fair trial, fairly fought. We find no reversible error in the district court’s denial of the defendants’ motions for JMOL or a new trial.
CONCLUSION
The judgment of the district court is
AFFIRMED.
Notes
. We note that although the jury appears to have accepted Micro Chemical’s damages theory, it reduced Lextron’s award by approximately one-third and Turnkey’s award by one-half.
