LYLE E. STROM, Senior District Judge..
This matter comes before the Court on common Daubert motions filed by defendants Sprint Spectrum ("Sprint"), T-Mobile U.S.A. ("T-Mobile"), United States Cellular Corp. ("U.S. Cellular"), and Cellco Partnership ("Cellco") (collectively, the "Carrier Defendants") in four related cases. In their motions (Filing No. 336 in 8:12CV123; Filing No. 290 in 8:12CV124; Filing No. 279 in 8:12CV125; and Filing No. 261 in 8:12CV126), defendants seek to exclude the expert opinion and testimony of Mr. Malackowski.
Prism accuses the Carrier Defendants of infringing upon its patents, 8,127,345 ("the `345 Patent") and 8,287,155 ("the `155 Patent"). Though Prism filed different actions against each Carrier Defendant, the parties agreed to common resolution of certain issues which affected all the cases. For example, Prism, AT&T Mobility, and the remaining Carrier Defendants agreed to resolve "common" issues in summary judgment and Daubert motions in addition to case specific issues. Filing No. 214. The Court adopted this policy and resolved the common issues pertaining to Prism's expert witnesses and various legal issues. The Court made a determination in the matter of Prism Technologies LLC v. AT&T Mobility, LLC (Docket No. 8:12CV122) (the "AT&T Matter") which plays into the Carrier Defendants' current motions. The Court granted the Carrier Defendants' motions to exclude the expert report and opinions of Mr. Malackowski, Prism's damages expert, due to the method of his damages calculations. Filing No. 246. Following the AT&T Matter, the Court granted Prism leave to amend the reports of its damages and validity experts based on agreements executed by Prism and AT&T Mobility, L.L.C. ("AT&T") that resolved the AT&T Matter.
Mr. Malackowski has offered three damages theories. The first was excluded. The second and third theories were introduced in his amended report. The Court finds the following illustration instructive in distinguishing the major differences between the theories:
(See Carrier Defendants' Slide No. 3 for Malackowski Daubert Hearing).
The Court must determine whether Mr. Malackowski's specialized knowledge will assist the trier of fact to understand evidence or to determine a fact at issue. Fed. R. Evid. 702. Under Rule 702, the Court must consider whether (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.
Royalty damage calculations are governed by case law:
ResQNet.com, Inc. v. Lansa, Inc., 594 F.3d 860, 868-69 (Fed. Cir. 2010). "A damages theory must be based on `sound economic and factual predicates.'" LaserDynamics, Inc., 694 F.3d at 67 (citing Riles v. Shell Exploration & Pro. Co., 298 F.3d 1302, 1311 (Fed. Cir. 2002)).
The proponent of the expert testimony must prove its admissibility by a preponderance of the evidence. Daubert, 509 U.S. at 592-93, n.10. "[T]estimony is inadmissible if it is speculative, unsupported by sufficient facts, or contrary to the facts of the case." Marmo v. Tyson Fresh Meats, Inc., 457 F.3d 748, 757 (8th Cir. 2006). "When the analytical gap between the data and proffered opinion is too great, the opinion must be excluded." General Elec. Co. v. Joiner, 522 U.S. 136, 146 (1997).
The Carrier Defendants object to the Second and Third theories on various grounds. After review of the filings, oral arguments and relevant case law, the Court will deny the Carrier Defendants' motions. Accordingly,
IT IS ORDERED:
1) In Case Number 8:12CV123, the defendant's motion (Filing No. 336) to exclude the testimony of Mr. Malackowski is denied.
2) In Case Number 8:12CV124, the defendant's motion (Filing No. 290) to exclude the testimony of Mr. Malackowski is denied.
3) In Case Number 8:12CV125, the defendant's motion (Filing No. 279) to exclude the testimony of Mr. Malackowski is denied.
4) In Case Number 8:12CV126, the defendant's motion (Filing No. 261) to exclude the testimony of Mr. Malackowski is denied.
