Important here, “[a] minor flaw in an expert’s reasoning or a slight modification of an otherwise reliable method will not render an expert’s opinion per se inadmissible.” “The judge should only exclude the evidence if the flaw is large enough that the expert lacks good grounds for his or her conclusions.” “This limitation on when evidence should be excluded accords with the liberal admissibility standards of the federal rules and recognizes that our adversary system provides the necessary tools for challenging reliable, albeit debatable, expert testimony.”
The defendant did not dispute Thomas’ expertise in music licensing, nor did it take issue with the five factors that Thomas stated, in her experience, usually affect the negotiated value of a music license. Instead, the defendant disputed her application of those factors to the facts at hand.
In the main, the Court found defendant’s objections were without merit, or went to the credibility of Thomas’s testimony, which were to be tested not by preclusion but by “[v]igorous cross-examination, presentation of contrary evidence, and careful instruction on the burden of proof,” which “are the traditional and appropriate means of attacking shaky but admissible evidence.”
The defendant did have one trenchant objection to Thomas’s report and testimony. Thomas estimated the fair market value of an appropriate license based on a perpetual term of use. But the measure of damages must be based on “the use the infringer made,” not unrealized risks created by the infringer’s use. Thomas’s decision to value the license and implied endorsement based on a perpetual term of use, when the law requires her to use a five-week term of use, was not a “minor flaw.” Rather, “the flaw is large enough” that, while it remained a basis for her report, the report “lacks good grounds for [its] conclusions.” This flaw, however, was eminently correctable, the court ruled. Thomas was allowed to render a prompt, revised opinion, that valued the license based on a factually defensible assumption as to the term of use.
In a subsequent May 7, 2014 ruling, Judge Engelmayer again refused to prohibit Thomas from testifying. The defendant argued that Thomas's estimate of damages was so vague as to be illusory. The Court wrote that Thomas "is not fairly to be faulted for acknowledging that inherent uncertainty in estimating the value of a unique, intangible good. In acknowledging that uncertainty, Thomas, in fact, keeps company with the Second Circuit, which, when it first approved the method of measuring a copyright holder's actual damages through the fair market value of a hypothetical license fee, recognized the difficulty of that exercise." The Court did, however, did preclude Thomas from testifying about the settlement of a widely-publicized dispute between the Beastie Boys and toymaker GoldieBlox under Federal Rule of Evidence 403. Judge Engelmayer wrote that "the confusion and delay occasioned by introduction of evidence as to the GoldieBlox Settlement would substantially outweigh -- indeed, it would overwhelm -- the limited probative value of the GoldieBlox testimony."
