Defendant.

MEMORANDUM AND ORDER

In this patent infringement suit, Plaintiff LoganTree LP alleges that Defendant Garmin International Inc.’s activity trackers infringe reexamined U.S. Patent No. 6,059,586 (the “ ‘576 Patent”). This matter comes before the Court on LoganTree’s Motion to Partially Exclude Certain Opinions of William R. Michalson Under Rule 702 (Doc. 215). Dr. Michalson is Garmin’s expert on non-infringement of the ‘576 Patent. For the reasons discussed below, the Court grants LoganTree’s motion. I. Legal Standard Federal Rule of Evidence 702 governs expert testimony. It provides that a witness “qualified as an expert by knowledge, skill, experience, training, or education” may provide opinion testimony if: (a) the expert’s scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue; (b) the testimony is based on sufficient facts or data;

(c) the testimony is the product of reliable principles and methods; and

(d) the expert has reliably applied the principles and methods to the facts of the case.1

Rule 702 imposes a “gatekeeping role” upon the district court to ensure that expert testimony is relevant and reliable and that it will assist the trier of fact.2 Under this rule, the Court must first “determine whether the expert is qualified by knowledge, skill, experience, training, or education to render an opinion.”3 If so, the Court “must determine whether the expert’s opinion is reliable by assessing the underlying reasoning and methodology.”4 And finally, the Court must examine “whether [the] proposed testimony is sufficiently ‘relevant to the task at hand.’ ”5 “Relevant evidence ‘means evidence having any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence.’ ”6 The party offering the expert testimony bears the burden of showing that it is admissible.7

Evid. 401). 7 Nacchio, 555 F.3d at 1241. “The [C]ourt has discretion to determine how to perform its gatekeeping function under Daubert.”8 The Court may, but is not required to, conduct a Daubert hearing to fulfill this role.9 Here, neither party has requested a Daubert hearing, and after reviewing the parties’ briefs, the Court concludes that the motion can be decided without a Daubert hearing. II. Analysis

Garmin offers Dr. Michalson as its expert on Garmin’s non-infringement of the ‘576 Patent. In Section XII of Dr. Michalson’s Expert Report, Dr. Michalson opines as to how the Garmin products accused of infringement in this litigation practice Garmin’s patents. LoganTree moves the Court to exclude this opinion at trial because it is legally impermissible and will not help the jury understand the evidence or determine a fact in issue. It is well-settled that “the existence of one’s own patent does not constitute a defense to infringement of someone else’s patent.”10 Thus, the Court agrees with LoganTree that Dr. Michalson cannot opine that Garmin’s products practice Garmin’s patents to support Garmin’s non-infringement defense.

Garmin does not dispute that Dr. Michalson’s opinion is not admissible to support Garmin’s non-infringement defense. Instead, Garmin argues that Dr. Michalson’s opinion is admissible because it is essential to Garmin’s critique of LoganTree’s damages claim. Garmin asserts that Garmin’s products include features unrelated to the step counting functionality that

YMC Royalty Co., LP, 918 F.3d 760, 770 (10th Cir. 2019)). 9 Id. (citing Goebel v. Denver & Rio Grande W. R.R. Co., 215 F.3d 1083, 1087 (10th Cir. 2000)). 10 Bio-Tech. Gen. Corp. v. Genentech, Inc., 80 F.3d 1553, 1559 (Fed. Cir. 1996) (quoting Vaupel Texilmaschinen KG v. Meccanica Euro Italia S.P.A., 944 F.2d 870, 879 n.4 (Fed. Cir. 1991)). LoganTree accuses of infringing the ‘576 Patent. As a result, Garmin argues that the amount of infringement damages must be apportioned so that LoganTree may only recover for the value of its invention rather than the value of the watches as a whole.11 Garmin asserts that several of its patents cover the additional features found in its products, and thus, the required apportionment analysis must analyze the value of the other patented components. According to Garmin, this

analysis involves Dr. Michalson first offering an opinion as to whether Garmin’s own patented technology was being used in the products. Then, Garmin’s economic expert, Dr. Finch, used Dr. Michalson’s technical opinions to analyze and critique LoganTree’s damages request by opining that LoganTree’s damages expert did not correctly apportion damages in his calculations. Even in this context, the Court concludes that Dr. Michalson’s opinion is not helpful to the jury.12 Garmin has not pointed to any evidence showing that Dr. Finch performed his own apportionment analysis in critiquing LoganTree’s damages claim. Instead, Dr. Finch opines that LoganTree’s damages expert was required to perform an apportionment analysis and that he did not do so. Dr. Finch provides no analysis as to what value Garmin’s patents would have within

the Accused Products or the amount by which that value reduces LoganTree’s damages calculation. Instead, he only opines that LoganTree’s expert failed to properly apportion damages. This critique could be made without reference to whether Garmin’s products practice Garmin’s
