Opinion

UNITED STATES DISTRICT COURT MIDDLE DISTRICT OF FLORIDA ORLANDO DIVISION X SOCIAL MEDIA LLC, Plaintiff, Vv. CASE NO. 6:23-cv-1903-JA-UAM X CORP., Defendant.

ORDER This case is before the Court on Defendant’s motion to strike (Doc. 51), Plaintiffs response (Doc. 54), and Defendant’s reply (Doc. 60). Based on the Court’s review of the parties’ submissions, the motion must be granted. I. BACKGROUND This is a case for trademark infringement relating to the parties’ use of the letter “X” in association with their respective businesses. (See Doc. 1 { 36). On January 22, 2024, the Court entered a scheduling order (Doc. 36) that set deadlines for the parties to disclose affirmative and rebuttal expert reports. Plaintiff did not disclose any affirmative expert reports by its deadline to do so, but Defendant served two affirmative expert reports: (1) a marketing report authored by Peter N. Golder, Ph.D., and (2) a consumer survey report on the likelihood of reverse confusion authored by Hal Poret.

On its rebuttal report deadline, Plaintiff served the “Rebuttal Report of David Franklyn” (Franklyn Report) (Doc. 51-1). Sections IX—XIV of the Franklyn Report include a reverse two-room Squirt! sequential lineup survey

as well as a survey to measure initial-interest confusion (Franklyn Surveys). (Doc. 51-1 at 43-93). Defendant argues sections IX—XIV should be struck because the Franklyn Surveys constitute untimely new affirmative opinions that go beyond proper rebuttal of Defendant's experts. Il. LEGAL STANDARDS The Federal Rules of Civil Procedure allow for rebuttal testimony when it “is intended solely to contradict or rebut evidence on the same subject matter identified by another party.” Fed. R. Civ. P. 26(a)(2)(D)G@i). “The term ‘same subject matter’ as used in Rule 26(a)(2)(D)Gi) has been construed broadly.” Wherevertv, Inc. v. Comcast Cable Comme’ns, LLC, No. 2:18-cv-529, 2022 WL

4017049, at *3 (M.D. Fla. Sept. 4, 2022) (citing Northrup v. Werner Enter., No. 8:14-cv-1627, 2015 WL 4756947, at *2 (M.D. Fla. Aug. 11, 2015)). However, “a rebuttal opinion should not be used to advance new arguments or present new evidence.” Id. at *3; Kendall Lakes Towers Condo. Ass’n, Inc. v. Pac. Ins. Co.,

1 SquirtCo v. Seven-Up Co., 628 F.2d 1086 (8th Cir. 1980) (establishing the “Squirt” test for likelihood of confusion in cases involving concurrent use of marks. In a “two-room reverse Squirt” survey, consumers are exposed to the junior mark in isolation and surveyed for potential confusion from prior exposure to the senior mark.

No. 10-24310-CIV, 2011 WL 6372198, at *4 (S.D. Fla. Dec. 20, 2011). Indeed, “fr]ebuttal testimony is permitted only when it directly addresses an assertion raised by an opponent’s experts.” Wherevertv, Inc., 2022 WL 4017049, at *3

(alteration in original) (quoting In re Trasylol Prods. Liab. Litig., No. 1:09-MD-

01928, 2010 WL 4065436, at *2 (S.D. Fla. Aug. 6, 2010)). “The purpose of rebuttal evidence is ‘to explain, repel, counteract, or

disprove the evidence of the adverse party,’ and the decision to permit rebuttal

testimony is one that resides in the sound discretion of the trial judge.” United

States v. Gold, 743 F.2d 800, 818 (11th Cir. 1984) (quoting United States v. Delk, 586 F.2d 513, 516 (5th Cir. 1978)).2 “Courts are empowered to exercise their

discretion and judgment in determining if a rebuttal expert report addresses the

same subject matter as the opposing party’s initial expert report.” Jd. (citing Lebron v. Royal Caribbean Cruises, Ltd., No. 16-24687, 2018 WL 3583002, at □□□

(S.D. Fla. July 26, 2018)). Federal district courts “are not hesitant to exclude or substantially limit expert opinion testimony at trial when an expert is

masquerading as a rebuttal expert.” Kroll v. Carnival Corp., No. 19-23017-CIV, 2020 WL 4793444, at *5 (S.D. Fla. Aug. 17, 2020) (collecting cases).

2 Decisions of the Fifth Circuit prior to October 1, 1981, are binding on the courts of the Eleventh Circuit. See Bonner v. City of Prichard, 661 F.2d 1206, 1209 (11th Cir. 1981).

Ill. DISCUSSION Defendant argues that the Franklyn Surveys are not responsive to its experts’ opinions and improperly advance new theories of the case beyond the deadline to submit affirmative expert opinions. In response, Plaintiff argues that the Franklyn Surveys properly rebut Defendant’s experts and that even if

the Court finds otherwise, admitting the Franklyn Surveys into evidence would be harmless. A. Untimely Affirmative Opinions The Franklyn Surveys include: (1) a reverse-confusion survey (Doc. 51-1

at 61—78) and (2) an initial-interest-confusion survey (id. at 79-92). Defendant

argues the Franklyn Surveys are untimely affirmative opinions. In support of

its argument, Defendant notes that the Franklyn Report acknowledges that it

contains Professor Franklyn’s “affirmative opinions based on [Professor Franklyn’s] own likelihood of confusion studies (the ‘Franklyn Surveys’) and rebuttal opinions regarding the expert reports produced by Hal Poret and Peter Golder.” (Doc. 51-1 at 6). Indeed, the Franklyn Report itself “ma[kes] clear” which sections of the report contain rebuttal opinion as opposed to affirmative opinions. (Doc. 51-1 at 6). For that reason alone, the Court could strike Professor Franklyn’s “clearly [] new affirmative opinion[s],” because such affirmative opinions were required to be served by the affirmative expert report deadline, not the rebuttal report deadline. See All-Tag Corp. v. Checkpoint Sys., Inc., 408

F. Supp. 3d 1347, 1352 (S.D. Fla. 2019). Nevertheless, the Court will consider

whether the Franklyn Surveys constitute proper rebuttal opinion despite their

designation in the Franklyn Report as affirmative opinions. Defendant argues that the initial-interest-confusion survey is improper because “initial interest confusion” is an entirely new theory that was set forth

for the first time in this litigation within the Franklyn Report. Defendant

contends that Plaintiff had only asserted a theory of “reverse confusion” prior to

serving the Franklyn Report. (Doc. 51 at 9 (citing Doc. 1 22, 23, 37, 61)). Thus, Defendant argues that Professor Franklyn’s initial-interest-confusion

survey is not plausibly within the scope of proper rebuttal to Defendant’s

experts. Moreover, Defendant argues that Professor Franklyn’s Squirt survey is

not plausibly issued in rebuttal to Defendant’s experts because Defendant's

experts do not rely on a Squirt survey. In response, Plaintiff argues that the

Franklyn Surveys address “the overall subject matter of likelihood of confusion.”

(Doc. 54 at 3). Plaintiff points to Franklyn’s “table of contents and summary of

opinions,” which Plaintiff claims “address[es] the flaws and omissions found in

the Porter [sic] Eveready survey.” (Id. at 4). Plaintiff also argues that the

findings in the Franklyn Survey can be used to cast doubt on the claims made

by Defendant’s experts. (Doc. 54 at 9-13).

As Plaintiff notes, courts within the Eleventh Circuit have agreed that the phrase “same subject matter” should not be “narrowly construed.” See 1550 Brickell Assocs. v. QBE Ins. Corp., No.
