BUZZBALLZ, LLC, Case No. 24-cv-04004-EKL

Plaintiff, ORDER DENYING SUMMARY v. JUDGMENT-RELATED DAUBERT MOTIONS Re: Dkt. Nos. 238, 243, 249, 253 Defendant.

Defendant MPL Brands NV, Inc. d/b/a Patco Brands (“Patco”) has moved for summary judgment on the trade dress infringement and unfair competition claims asserted by Plaintiff BuzzBallz, LLC (“BuzzBallz”). This Order addresses a subset of issues raised in the parties’ Daubert motions that are relevant to the summary judgment motion. See ECF Nos. 302, 307. The relevant Daubert motions seek to exclude: (1) the functionality opinions offered by BuzzBallz’s experts Arthur Shapiro and Glenn May; (2) the functionality and genericness opinions offered by Patco’s expert Charles L. Mauro; and (3) the secondary meaning survey offered by BuzzBallz’s expert David Franklyn. See ECF Nos. 238, 243, 249, 253, 302, 307. Having reviewed the parties’ submissions and relevant authority, the Court finds these motions suitable for resolution without oral argument. Civil L.R. 7-1(b). The Daubert motions are DENIED in part for the following reasons. A. Functionality and Genericness Opinions The parties disclosed three experts to opine, in part, on whether BuzzBallz’s asserted trade dress is functional, and therefore not protectable. Consistent with the case schedule for expert discovery, BuzzBallz disclosed Shapiro, then Patco disclosed Mauro as a rebuttal expert on Mauro’s functionality opinions, among others. See Shapiro Report, ECF No. 250-9; Mauro Report, ECF No. 239-14; May Report, ECF No. 248-2. Patco moves to exclude the functionality opinions offered by Shapiro and May, asserting that BuzzBallz failed to timely disclose the experts’ theories of non-functionality during fact discovery. Mot. to Exclude May at 6-7, ECF No. 249 (“May Daubert”); Mot. to Exclude Shapiro at 9-10, ECF No. 253 (“Shapiro Daubert”). BuzzBallz moves to exclude the opinions offered by Mauro, contending that they are inconsistent with the relevant legal standards for functionality and genericness. Mot. to Exclude Mauro at 8- 10, ECF No. 243 (“Mauro Daubert”). The Court addresses these arguments in turn. 1. Shapiro and May Federal Rule of Civil Procedure 26(a)(2) “requires litigants to disclose all expert witnesses ‘at the times and in the sequence that the court orders.’” Merchant v. Corizon Health, Inc., 993 F.3d 733, 739 (9th Cir. 2021) (quoting Goodman v. Staples The Office Superstore, LLC, 644 F.3d 817, 827 (9th Cir. 2011)). Rule 26(e) provides that a party must supplement or correct its Rule 26(a) disclosures and discovery responses in “a timely manner if the party learns that in some material respect the disclosure or response is incomplete or incorrect, and if the additional or corrective information has not otherwise been made known to the other parties during the discovery process or in writing.” Fed. R. Civ. P. 26(e). “If a party fails to provide information or identify a witness as required by Rule 26(a) or (e), the party is not allowed to use that information or witness to supply evidence on a motion, at a hearing, or at trial, unless the failure was substantially justified or is harmless.” Fed. R. Civ. P. 37(c)(1). The party proffering an untimely expert has the burden to prove that the late disclosure was substantially justified or harmless. Yeti by Molly, Ltd. v. Deckers Outdoor Corp., 259 F.3d 1101, 1106-07 (9th Cir. 2001). Rebuttal reports are “intended solely to contradict or rebut evidence on the same subject matter identified by another party” in that party’s expert disclosures. Fed. R. Civ. P. 26(a)(2)(D)(ii). “The test of whether an expert’s opinion constitutes rebuttal or a new opinion, however, is not whether a rebuttal expert employs new testing or methodologies but instead, whether a rebuttal attempts to put forward new theories outside the scope of the report it claims to (citation modified). There is no absolute requirement that the party with the burden of proof on an issue must disclose affirmative expert testimony on that issue. See Fed. R. Civ. P. 26 advisory committee’s note to 1993 amendment (recognizing that “in most cases the party with the burden of proof on an issue should disclose its expert testimony on that issue before other parties are required to make their disclosures with respect to that issue” (emphasis added)). Here, Patco argues that Shapiro and May’s opinions regarding non-functionality should be excluded because BuzzBallz failed to disclose their non-functionality theories during fact discovery in response to an interrogatory. May Daubert at 6-7; Shapiro Daubert at 9. Patco also contends that May’s opinions should be excluded because they were disclosed for the first time in a reply report. May Daubert at 6-7. These arguments are not persuasive. First, BuzzBallz’s response to the interrogatory was adequate. The interrogatory requested that BuzzBallz “[s]tate the complete factual and legal basis for [its] contention that [its] unregistered [a]sserted [t]rade [d]ress is protectable.” ECF No. 249-5 at 9. BuzzBallz’s response included a short narrative identifying BuzzBallz’s contentions, including its assertion that the trade dress is non-functional, and referred Patco to more than 20 documents “containing information concerning the protectability” of its trade dress, as permitted by Federal Rule of Civil Procedure 33(d). ECF No. 249-5 at 9-11. BuzzBallz also responded that it would “submit further evidence responsive to this interrogatory when expert reports are due.” Id. at 11. BuzzBallz’s response provided the factual and legal bases for its contention that the asserted trade dress is protectable. BuzzBallz was not required to disclose the details of its forthcoming expert reports in response to the interrogatory before the reports were due under the case schedule. In addition, Patco deposed both Shapiro and May after they disclosed their non- functionality opinions. See ECF Nos. 272-6, 274-2; Icon-IP Pty Ltd. v. Specialized Bicycle Components, Inc., 87 F. Supp. 3d 928, 951 (N.D. Cal. 2015) (declining to exclude expert where party moving to exclude “had the opportunity to depose him”). Accordingly, the Court declines to exclude Shapiro and May’s non-functionality opinions due to BuzzBallz’s interrogatory response.1 Second, it was not improper for BuzzBallz to disclose May’s non-functionality opinions in a reply report because the opinions fall squarely within the scope of proper rebuttal. May directly tied his analysis to Mauro’s report and the evidence upon which Mauro relied. See, e.g., May Report ¶¶ 55-57, 63, 67-71. Patco identifies only one “theory” of non-functionality in May’s report that it claims should have been disclosed earlier in response to the interrogatory. May Daubert at 7. But the relevant example is a direct response to Mauro’s report, not a new theory. Compare Mauro Report ¶ 69 (opining that the shape of a BuzzBallz container is functional for purposes of “distribution and shipping logistics” and “how the cans stack”), with May Report ¶¶ 52-54 (responding that the rounded container shape has disadvantages with respect to distribution and stacking that render it non-functional).
