8 Plaintiff,

GRANTING DEFENDANTS’ MOTION

9 v. FOR SUMMARY JUDGMENT

10 REALMARK HOLDINGS, LLC, et al., Re: Dkt. No. 71 Defendants. 11

12 13 Robert Serafin brings this action against Realmark Holdings, LLC and Realmark, Inc. (the 14 “Realmark Defendants”), his former wife Madeline Serafin, and other unnamed Doe defendants. 15 The named defendants now move for summary judgment. For the reasons set forth herein, the 16 Court grants defendants’ motion for summary judgment on Mr. Serafin’s Lanham Act claims and 17 related state law claims and declines to exercise jurisdiction over the remaining state law claims. 18 BACKGROUND 19 As explained in this Court’s order denying the Realmark Defendants’ motion to dismiss 20 and stay, Mr. Serafin alleges that he and Ms. Serafin have each held a 50% ownership stake in 21 Realmark, Inc. since they formed and incorporated the entity together in 2014. Mr. Serafin further 22 alleges that the mark “Realmark” is associated with Realmark, Inc. and helps promote the 23 company’s real estate services in the Bay Area. 24 Mr. Serafin alleges in his complaint that Ms. Serafin and the Doe defendants created a new 25 entity, Realmark Holdings, LLC, in late 2022. The complaint alleges Realmark Holdings, LLC 26 assumed Realmark, Inc.’s website to offer the same or similar services in an attempt to deceive, 27 confuse, and ultimately transfer customers from Realmark, Inc. to Realmark Holdings, LLC. The 1 LLC to Mr. Serafin’s detriment. 2 Mr. Serafin’s suit contains two claims for violations of Section 43(a) of the federal 3 Lanham Act and eight state law claims. Mr. Serafin seeks both monetary damages and injunctive 4 relief. 5 On August 9, 2023, the Realmark Defendants moved to dismiss Mr. Serafin’s complaint or 6 stay this action pending the resolution of a Contra Costa County Superior Court marital 7 dissolution action between the Serafins. On October 26, 2023, the Court denied the motion. 8 The Realmark Defendants and Madeline Serafin now move for summary judgment. 9 LEGAL STANDARD 10 Courts may grant summary judgment “if the movant shows that there is no genuine dispute 11 as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 12 56(a). A factual dispute is genuine “if the evidence is such that a reasonable jury could return a 13 verdict for the nonmoving party.” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986). A 14 dispute is material if it “might affect the outcome of the suit under the governing law.” Id. 15 The moving party bears the initial burden to demonstrate a lack of genuine factual dispute. 16 Celotex Corp. v. Catrett, 477 U.S. 317, 323 (1986). “When the nonmoving party has the burden of 17 proof at trial, the moving party need only point out ‘that there is an absence of evidence to support 18 the nonmoving party’s case.’” Devereaux v. Abbey, 263 F.3d 1070, 1076 (9th Cir. 2001) (quoting 19 Celotex Corp., 477 U.S. at 325). The burden then shifts to the nonmoving party to “provide 20 affidavits or other sources of evidence that ‘set forth specific facts showing that there is a genuine 21 issue for trial.’” Id. at 1076 (quoting Fed. R. Civ. P. 56(e)). Courts “must view the evidence 22 presented through the prism of the substantive evidentiary burden.” Anderson, 477 U.S. at 254. 23 “The evidence of the non-movant is to be believed, and all justifiable inferences are to be drawn in 24 his favor.” Id. at 255. 25 ANALYSIS 26 I. Defendants’ motion for summary judgment on claims 1–5 is granted. 27 Defendants move for summary judgment on Mr. Serafin’s Lanham Act claims (the first 1 Serafin has no evidence demonstrating his ownership interest in the trademark; and (2) Mr. Serafin 2 has no evidence to prove that Realmark Holdings, LLC committed trademark infringement. The 3 Court agrees. 4 There are two bases for liability under section 43(a) of the Lanham Act: (1) false 5 association, 15 U.S.C. § 1125(a)(1)(A); and (2) false advertising, 15 U.S.C. § 1125(a)(1)(B). 6 Lexmark Intern., Inc. v. Static Control Components, Inc., 572 U.S. 118, 122 (2014). Here, Mr. 7 Serafin relies upon a false association theory for both of his section 43(a) claims.1 To have 8 statutory standing to bring a false association claim, a plaintiff suing for trademark infringement 9 must establish that they are “(1) the owner of a federal mark registration, (2) the owner of an 10 unregistered mark, or (3) a nonowner with a cognizable interest in the allegedly infringed 11 trademark.” Halicki Films, LLC. v. Sanderson Sales & Mktg., 547 F.3d 1213, 1225 (9th Cir. 12 2008). 13 Mr. Serafin argues that he possesses standing because “he co-founded Realmark Inc. with 14 Madeline Serafin in 2014 and has remained a 50% shareholder throughout its existence” and 15 because “[t]he ‘Realmark’ mark has been continuously associated with Realmark Inc., a business 16 recognized in the Bay Area real estate market, and Plaintiff has a direct economic interest in its 17 reputation and client base.” In his opposition to defendants’ summary judgment motion, however, 18 Mr. Serafin cites no evidence in support of this argument, relying instead exclusively upon the 19 allegations in his unverified complaint. Such allegations cannot create a genuine dispute of 20 material fact at summary judgment. Lujan v. Defenders of Wildlife 504 U.S. 555, 561 (1992). (“In 21 response to a summary judgment motion, [ ] the plaintiff can no longer rest on [ ] mere allegations 22 but must set forth by affidavit or other evidence the specific facts, which for purposes of summary 23 judgment, will be taken as true.” (internal quotations omitted)). 24 Although Mr. Serafin was required to identify in his opposition with reasonable 25 particularity the evidence that precludes summary judgment but failed to do so, see Keenan v. 26

27 1 Mr. Serafin’s opposition to the pending motion confirmed that he is only pursuing a false 1 Allan, 91 F.3d 1275, 1279 (9th Cir. 1996) (noting that it is not the task of the district court “to 2 scour the record in search of a genuine issue of triable fact”), the Court has nonetheless reviewed 3 the evidence that Mr. Serafin attached to his opposition to determine whether it creates any 4 material and genuine issues of material fact. 5 The only evidence potentially relevant to determining whether Mr. Serafin has an 6 ownership interest sufficient to provide statutory standing is a declaration from Mr. Serafin 7 himself that states, in relevant part:

8 I am a co-founder and 50% shareholder of Realmark Inc., a California 9 corporation formed in 2014. I was actively involved in its operations and branding since its inception until I was improperly removed from 10 all positions by Madeline Serafin in July 2021, and my access to all Realmark systems, books, accounts, and operations terminated. 11 12 As the Ninth Circuit has made clear, such a declaration is not necessarily sufficient to preclude 13 summary judgment. “[A] self-serving declaration does not always create a genuine issue of 14 material fact for summary judgment: The district court can disregard a self-serving declaration that 15 states only conclusions and not facts that would be admissible evidence.” Nigro v. Sears, Roebuck 16 & Co., 784 F.3d 495, 497 (9th Cir. 2015). Whether or not Mr. Serafin’s declaration would be 17 admissible to prove some of the other facts quoted above, whether Mr. Serafin possesses 18 “ownership” of Realmark, Inc. is a legal conclusion. As a result, his statement that he is a 50% 19 shareholder of the corporation, standing alone, is insufficient to create a genuine dispute of fact as 20 to ownership. 21 Crucially, Mr. Serafin has provided no evidence beyond his self-serving declaration to 22 establish his ownership stake in Realmark, Inc. His declaration includes two exhibits, but they do 23 not support the asserted facts. The first includes several checks that, in Mr. Serafin’s view, show 24 Ms. Serafin improperly transferring funds from Realmark, Inc. to herself. These checks do not 25 establish his personal ownership interest in any way. The second is a letter sent to Realmark Inc. 26 by attorney Charles Throckmorton on December 18, 2023, that notes that “Striking Distance has 27 individual claims against Madeline Serafin, whom we understand is the sole owner of Realmark” 1 Serafin’s ownership of the corporation; if anything, it supports defendants’ claim that he lacks 2 such an interest.2 3 In addition, Mr. Serafin fails to identify admissible evidence suggesting defendants’ 4 infringement of the Realmark trademark. “To prove trademark infringement, a trademark holder 5 must show that the defendant’s use of its trademark is likely to cause confusion, or to cause 6 mistake, or to deceive.” See Adobe Sys. Inc. v. Christenson, 809 F.3d 1071, 1081 (9th Cir. 2015); 7 see also JUUL Labs, Inc. v. Chou, 557 F. Supp. 3d 1041, 1053 (C.D. Cal. 2021). Mr. Serafin has 8 not introduced evidence to suggest that Realmark, LLC is using the Realmark trademark at all, let 9 alone in a manner that is likely to cause confusion, mistake, or deception. For the same reason, 10 Mr. Serafin has introduced no evidence to suggest trademark infringement under his California 11 common law trademark infringement claim. See M2 Software, Inc. v. Madacy Entertainment, 421 12 F.3d 1073, 1080 (9th Cir. 2005) (explaining that the same test for trademark infringement applies 13 for federal Lanham Act and California common law claims). 14 Mr. Serafin has also introduced no evidence to create a genuine dispute of material fact as 15 to his California common law trademark dilution claim. “In order to prove [such] a violation, a 16 plaintiff must show that (1) the mark is famous and distinctive; (2) the defendant is making use of 17 the mark in commerce; (3) the defendant’s use began after the mark became famous; and (4) the 18 defendant’s use of the mark is likely to cause dilution by blurring or dilution by tarnishment.” 19 Jada Toys, Inc. v. Mattel, Inc., 518 F.3d 628, 634 (9th Cir. 2008). Mr. Serafin provides no 20 evidence to create a genuine dispute of material fact as to any of these elements. 21 Mr. Serafin also introduces no evidence in support of his fifth claim for violation of 22 California’s Unfair Competition Law (“UCL”), Cal. Bus. & Prof. Code § 17200 et seq., which is 23

24 2 Mr. Serafin also attaches to his opposition a copy of an apparent Realmark, Inc. bank account application in which he is listed as the “Treasurer & Secretary” of Realmark, Inc. Dkt. No. 72, at 25 18. A separate page lists a place for the “[o]wner” signatures and includes signatures from both Ms. and Mr. Serafin. Id. at 19. This evidence has not been authenticated by Mr. Serafin and 26 therefore cannot be considered at summary judgment. And in any event, it does not directly address the parties’ ownership interests in the corporation. Whether or not Mr. Serafin was treated 27 as an “owner” of any bank account opened in the corporation’s name—a status that presumably is 1 premised on defendants’ alleged improper use of the Realmark trademark. 2 Because Mr. Serafin has not identified evidence from which a jury could find either 3 statutory standing or infringement, defendants’ motion for summary judgment on his first and 4 fourth claims for violation of the Lanham Act is granted. Likewise, the Court grants defendants’ 5 motion for summary judgment on Mr. Serafin’s second and third California common law 6 trademark claims and fifth UCL claim. 7 II. The Court declines to exercise jurisdiction over the remaining state law claims. 8 Because the Court has granted summary judgment against Mr. Serafin on his federal 9 trademark claims (and the closely related state law claims), the Court, in its discretion, declines to 10 assert supplemental jurisdiction over the remaining state law claims for interference with 11 prospective economic advantage, breach of fiduciary duty, and unjust enrichment. “A district court 12 ‘may decline to exercise supplemental jurisdiction’ if it ‘has dismissed all claims over which it has 13 original jurisdiction.’” Sanford v. MemberWorks, Inc., 625 F.3d 550, 561 (9th Cir. 2010) (quoting 14 28 U.S.C. § 1367(c)(3)). The only potential basis for maintaining jurisdiction over Mr. Serafin’s 15 remaining state law claims is supplemental jurisdiction under 28 U.S.C. § 1367. “[I]n the usual 16 case in which all federal-law claims are eliminated before trial, the balance of factors to be 17 considered under the pendent jurisdiction doctrine—judicial economy, convenience, fairness, and 18 comity—will point toward declining to exercise [supplemental] jurisdiction over the remaining 19 state-law claims.” Carnegie-Mellon Univ. v. Cohill, 484 U.S. 343, 350 n.7 (1988). 20 Mr. Serafin’s remaining state law claims require analysis into specific state law and are not 21 resolved by the summary judgment on Mr. Serafin’s federal trademark claims and the closely 22 related state law claims. Considering judicial economy, convenience, fairness, and comity, it is 23 clear that the balance of the factors favors declining to exercise supplemental jurisdiction over 24 those claims. Accordingly, the Court, in its discretion, dismisses claims 6–10 of the complaint 25 without prejudice. 26 CONCLUSION 27 For the reasons set forth herein, the Court grants defendants’ motion for summary 1 exercise supplemental jurisdiction over claims 6 through 10. The Court enters judgment in 2 defendants’ favor and against Mr. Serafin on claims 1 through 5, and dismisses claims 6 through 3 10 without prejudice. 4 5 IT IS SO ORDERED. 6 || Dated: August 28, 2025 leo~ 8 gb P.
