error.” Prunty v. Ark. Freightways, Inc., 16 F.3d 649, 652 (5th Cir. 1994). MGE’s decision to seek GE/PMI’s profits was clearly a last-minute attempt to save its copyright infringement claim from dismissal for failure to prove damages. MGE has not succeeded. GE/PMI presented evidence that approximately 10% of PMI’s UPS service business came from MGE-branded machines, and MGE’s software was usable only with MGE UPS machines and not with competitors’ products. Thus, PMI’s total revenue far exceeds the approximately 10% of revenue reasonably related to the infringement of MGE’s copyright. MGE needed to present a more narrowly tailored calculation of PMI’s profits in order to cognize a claim for copyright damages “attributable to the infringement.” Accordingly, the district court erred in denying GE/PMI’s Rule 50(a) motion on MGE’s copyright infringement claims because MGE has not shown damages under § 504(b).

At the close of MGE’s case, the only evidence introduced to support its damages claims was the aforementioned DX-37 chart showing PMI’s total revenues earned from all sources of income. GE/PMI contends that without evidence of PMI’s net profits earned on the MGE equipment at issue, MGE’s state law claims should have been dismissed on GE/PMI’s Rule 50(a) motion.
There is little precedent under Texas law to guide us in determining whether MGE has sustained the burden of proof required of a plaintiff seeking to recover a defendant’s net profits. In the only reported Texas case involving the recovery of defendant’s profits for a misappropriation of trade secrets claim, the Dallas Court of Appeals held that although defendant’s profits are a “proper element[ ] of damages in a case involving the wrongful use of a trade secret,” a
