A model's reading — qwen3.8-27b, prompt own-v1, 2026-10-14T00:04Z · confidence high

The court considered cross-motions for summary judgment in a false advertising and unfair competition dispute regarding competing thyroid disease assays. The court granted summary judgment to the defendants on claims concerning deception of laboratories but denied summary judgment on claims concerning deception of physicians and on the unclean hands defense, while also denying the plaintiff's motion for summary judgment on the element of falsity.

What the court decidedStandard it appliedThe model
Granting in part Defendants' Motion for Summary Judgment
“The Court GRANTS summary judgment for the first three causes of action as they relate to Plaintiffs claims regarding deception of the laboratories.”
de novoagree with court
The court correctly applied the Rule 56 standard, finding that while there was a dispute of material fact regarding the literal falsity of the 'TSI only' claim, there was no genuine dispute regarding materiality or deception as to the specific customers (laboratories) who switched products. The deposition testimony from the laboratory representatives established that their purchasing decisions were based on internal validation studies and performance data, not the specific marketing claims at issue. This satisfies the requirement that the plaintiff must show the deception was material to the purchasing decision.
Denying in part Defendants' Motion for Summary Judgment
“The Court DENIES Defendants’ motion for summary judgment as it relates to the physicians”
de novoagree with court
The court correctly identified a genuine issue of material fact regarding whether physicians are part of the relevant purchasing market and whether they were deceived. The evidence presented, including testimony that physicians drive demand and a survey suggesting deception, was sufficient to preclude summary judgment on this segment of the market.
Denying Defendants' Motion for Summary Judgment based on Unclean Hands
“The Court DENIES Defendants’ motion for summary judgment based on the unclean hands defense.”
de novoagree with court
The court correctly applied the unclean hands doctrine, which requires a showing that the plaintiff's inequitable conduct relates to the subject matter of the claims. The court found a genuine dispute of fact regarding whether the plaintiff's own advertising was false (precluding a finding of inequitable conduct based on that theory) and found the alleged billing code scheme was not sufficiently related to the remaining claims regarding physician deception.
Denying Plaintiff's Motion for Summary Judgment
“The Court DENIES Plaintiff’s Motion.”
de novoagree with court
The court correctly denied the plaintiff's motion because the plaintiff failed to establish the element of falsity as a matter of law. The presence of conflicting expert testimony regarding whether the defendant's assay actually detects 'TSI only' created a genuine issue of material fact, precluding summary judgment in the plaintiff's favor on that element.

The order itself: sound — The order is sound. It correctly applies the Rule 56 standard to the specific facts of the case. It properly distinguishes between the element of falsity (where a genuine dispute exists due to conflicting expert testimony) and the elements of materiality/deception (where summary judgment is appropriate for the laboratory segment based on direct evidence of the decision-making process, but not for the physician segment). The application of the unclean hands doctrine is also consistent with Ninth Circuit precedent regarding the necessity of a nexus between the plaintiff's misconduct and the claims at issue.

5 6 7 8 UNITED STATES DISTRICT COURT 9 SOUTHERN DISTRICT OF CALIFORNIA 10 QUIDEL CORPORATION, Case No. 16-cv-3059-BAS-AGS 11 Plaintiff, ORDER: 12 (1) GRANTING IN PART AND DENYING IN PART 13 v. DEFENDANTS’ MOTION FOR SUMMARY 14 SIEMENS MEDICAL SOLUTIONS JUDGMENT; AND USA, INC., et al., 15 (2) DENYING PLAINTIFF’S Defendants. MOTION FOR SUMMARY 16 JUDGMENT 17 [ECF Nos. 138, 145]

19 20 After three years of litigation, this case has reached the summary judgment 21 stage, and both parties seek summary judgment in their favor. Defendants Siemens 22 Medical Solutions USA, Inc. and Siemens Healthcare Diagnostics Inc. move for 23 summary judgment on all claims, (“Def. Mot.,” ECF No. 138), and Plaintiff Quidel 24 Corporation moves for summary judgment on the element of falsity. (“Pl. Mot.,” 25 ECF No. 145.) Both motions are opposed, (“Pl. Opp’n,” ECF No. 169; “Def. Opp’n,” 26 ECF No. 166).1 The Court finds the Motions suitable for determination on the papers 27 1 and without oral argument. Civ. L. R. 7.1(d)(1). For the reasons stated below, the 2 Court GRANTS IN PART Defendants’ Motion and DENIES Plaintiff’s Motion. 3 BACKGROUND 4 This case revolves around two competing assays (blood tests) used for 5 measuring thyroid stimulating immunoglobins, which can aid in the detection of 6 Graves’ disease. Graves’ disease is an immune system disorder that leads to the 7 overproduction of thyroid hormones. Generally, there are two types of assays 8 available to aid in the diagnosis of Graves’ disease: (1) TSH receptor antibody 9 (TRAb) assays and (2) TSI only assays. TRAb assays detect both stimulating and 10 blocking thyroid immunoglobins (also known as “TSI” and “TBI”), while TSI only 11 assays detect only stimulating immunoglobins. 12 Plaintiff entered the market first, and in 2008 submitted its product, Thyretain 13 TSI Reporter BioAssay (“Thyretain”), for FDA approval. (See Exhibit 4 to 14 Declaration of Erik Haas, ECF No. 140-1.) The FDA cleared Thyretain in 2009. 15 Plaintiff advertises Thyretain as a “TSI only” assay. (Exhibit 1 to Declaration of Erik 16 Haas, ECF No. 140, at 210:6–10.) According to Plaintiff, “Thyretain is a cell-based 17 assay that measures the functional activity of TSH receptor antibodies and returns a 18 positive result when TSI bind to the stimulating epitope of the TSH receptor.” (Pl. 19 Opp’n at 2 (emphasis omitted).) If TSI is detected, this is a positive result, and a 20 light is emitted. This is known as a qualitative result. 21 Defendants entered the market in 2012 with their product IMMULITE, using 22 Thyretain as the predicate device for their 510(k) application to the FDA.2 (Exhibit 23 paragraph. Although this is not a substantial violation of the rules, it is a violation nonetheless and 24 the Court does not appreciate Plaintiff’s attempt to gain an advantage by presenting extra material 25 in briefing. The Court STRIKES page 26 of Plaintiff’s opposition brief, (ECF No. 169). 2 There are two main processes though which the FDA reviews medical devices and either approves 26 or clears them for use: the Premarket Approval (PMA) Process and the 510(k) PMN (or Premarket Clearance) Process. Under the 510(k) process, “if a device is deemed ‘substantially equivalent’ to 27 a pre-existing device with prior clearance, ‘it can be marketed without further regulatory analysis.’” 1 5 to Declaration of T. Kevin Roosevelt, ECF No. 171, at 4.) In applying to the FDA, 2 Defendants acknowledged that Plaintiff’s product was “the only FDA-cleared TSI 3 assay on the market at this time” while other approved TRAb assays “detect both 4 stimulating and blocking thyroid antibodies” and had inferior “specificity for Graves’ 5 disease.” (Id.) While Thyretain is a bioassay, IMMULITE is an immunoassay. (Def. 6 Mot. 4; Pl. Mot. 4.) According to Defendants, IMMULITE “uses a novel ‘bridge’ 7 technology which links the receptors that bind with TSI to signal receptors. Those 8 signal receptors in turn emit light that may be measured in a ‘semi-quantitative’ 9 manner, depicting the concentration of TSI in a sample, rather than just a binary 10 ‘qualitative’ result.” (Def. Mot. at 4.) 11 The crux of this matter lies in Defendants’ advertising of IMMULITE. In 12 Plaintiff’s opinion, IMMULITE, as an immunoassay, “measures the binding of 13 antibodies to the TSH receptor without discrimination,” meaning it does not 14 distinguish between stimulating or blocking antibodies. (Pl. Opp’n at 3.) Plaintiff 15 argues IMMULITE “has the potential to and actually does detect blocking 16 antibodies.” (Id. at 3.) However, Defendants advertised IMMULITE as a “TSI only” 17 assay (i.e. one that does distinguish between stimulating and blocking antibodies). 18 Defendants’ proclaiming of IMMULITE to be an assay that detects TSI only 19 is undisputed. In its de novo request to the FDA, Defendants classified IMMULITE 20 as an assay that “measures stimulating immunoglobins only.” (Exhibit U to 21 Declaration of T. Kevin Roosevelt, ECF No. 147; see also Exhibit 29 to Declaration 22 of T. Kevin Roosevelt, ECF No. 169-1 (Defendants’ 510(k) Premarket Notification: 23 “TRAb assays measure both [TBI and TSI] quantitatively without distinguishing 24 between the two, whereas the IMMULITE 2000 TSI measures stimulating 25 immunoglobins only.”)). After the FDA cleared the product, Defendants sent out 26 information to potential customers on the product, saying IMMULITE “utilizes 27 1 recombinant human TSH receptors (hTSHR) for the specific detection of thyroid 2 stimulating autoantibodies.” (Exhibit 23 to Declaration of T. Kevin Roosevelt, ECF 3 No. 171.) Defendants distinguished IMMULITE from “TSHR autoantibody (TRAb) 4 assays [which] do not distinguish between TSI and TBI.” (Id.). Similar statements 5 appeared on Defendants’ website. (See, e.g., Exhibit T to Declaration of T. Kevin 6 Roosevelt, ECF No. 147-3, at 51:3–10 (testimony regarding Defendants’ website in 7 May 2016).) 8 Defendants advertised IMMULITE as “TSI only” for a few months. (Def. 9 Mot. at 7–8.) When Plaintiff protested this advertising, Defendants dropped the “TSI 10 only” claim. (Id.) Plaintiff argues that advertising IMMULITE in this way was false 11 and has caused Plaintiff damages. Specifically, before IMMULITE entered the 12 market, Quidel had four U.S. customers, which were four laboratories, two of which 13 were LabCorp and Sonic. LabCorp and Sonic since have switched to using 14 IMMULITE. (Id. at 12.) Whether these two customers (and others) considered or 15 were deceived by Defendants’ advertising in making the decision to switch is an issue 16 in this case. 17 LEGAL STANDARD 18 Summary judgment is appropriate under Rule 56(c) where the moving party 19 demonstrates the absence of a genuine issue of material fact and entitlement to 20 judgment as a matter of law. See Fed. R. Civ. P. 56(c); Celotex Corp. v. Catrett, 477 21 U.S. 317, 322 (1986). A fact is material when, under the governing substantive law, 22 it could affect the outcome of the case. Anderson v. Liberty Lobby, Inc., 477 U.S. 23 242, 248 (1986). A dispute about a material fact is genuine if “the evidence is such 24 that a reasonable jury could return a verdict for the nonmoving party.” Id. 25 A party seeking summary judgment always bears the initial burden of 26 establishing the absence of a genuine issue of material fact. Celotex, 477 U.S. at 323. 27 The moving party can satisfy this burden in two ways: (1) by presenting evidence 1 demonstrating that the nonmoving party failed to make a showing sufficient to 2 establish an element essential to that party’s case on which that party will bear the 3 burden of proof at trial. Id. at 322–23. “Disputes over irrelevant or unnecessary facts 4 will not preclude a grant of summary judgment.” T.W. Elec. Serv., Inc. v. Pac. Elec. 5 Contractors Ass’n, 809 F.2d 626, 630 (9th Cir. 1987). 6 If the moving party fails to discharge this initial burden, summary judgment 7 must be denied, and the court need not consider the nonmoving party’s evidence. 8 Adickes v. S.H. Kress & Co., 398 U.S. 144, 159–60 (1970). If the moving party 9 meets this initial burden, however, the nonmoving party cannot defeat summary 10 judgment merely by demonstrating “that there is some metaphysical doubt as to the 11 material facts.” Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 12 586 (1986); Triton Energy Corp. v. Square D Co., 68 F.3d 1216, 1221 (9th Cir. 1995) 13 (“The mere existence of a scintilla of evidence in support of the non-moving party’s 14 position is not sufficient.” (citing Anderson, 477 U.S. at 242, 252)). Rather, the 15 nonmoving party must “go beyond the pleadings” and by “the depositions, answers 16 to interrogatories, and admissions on file,” designate “specific facts showing that 17 there is a genuine issue for trial.” Celotex, 477 U.S. at 324 (quoting Fed. R. Civ. P. 18 56(e)). Such admissions may be presented in testimony of a party’s own witnesses 19 through declarations. See Fed. R. Civ. Pro. 56(c)(4). 20 When making this determination, the court must view all inferences drawn 21 from the underlying facts in the light most favorable to the nonmoving party. See 22 Matsushita, 475 U.S. at 587. “Credibility determinations, the weighing of the 23 evidence, and the drawing of legitimate inferences from the facts are jury functions, 24 not those of a judge, [when] he [or she] is ruling on a motion for summary judgment.” 25 Anderson, 477 U.S. at 255. 26 DEFENDANTS’ MOTION FOR SUMMARY JUDGMENT 27 Defendants move for summary judgment on Plaintiff’s Lanham Act false 1 § 17200), and False Advertising Law claims (Cal. Bus. & Prof. Code § 17500).3 2 Defendants argue they should be granted judgment on various grounds: (1) 3 Defendants’ advertising is not false or deceptive; (2) the message in the advertising 4 is immaterial and did not cause injury to Plaintiff; and (3) Plaintiff’s unclean hands 5 bar its claims. 6 The statements at issue are 7 (1) that the IMMULITE Assay detects TSI only, (2) that the IMMULITE Assay is a “TSI assay” that detects TSI only, and (3) that 8 TRAb assays are distinguishable from the IMMULITE Assay, while 9 failing to disclose that the IMMULITE Assay is substantially similar to TRAb assays that fail to differentiate between stimulating and blocking 10 antibodies. 11 12 (First Amended Complaint, ECF No. 12, ¶ 24.) These can be summed up to one 13 overarching statement: IMMULITE detects TSI only. 14 A. Legal Standard 15 The same legal standard applies to all three of Plaintiff’s causes of action. The 16 elements of a Lanham Act § 43(a) false advertising claim are: 17 (1) a false statement of fact by the defendant in a commercial advertisement about its own or another’s product; (2) the statement 18 actually deceived or has the tendency to deceive a substantial segment 19 of its audience; (3) the deception is material, in that it is likely to influence the purchasing decision; (4) the defendant caused its false 20 statement to enter interstate commerce; and (5) the plaintiff has been or 21 is likely to be injured as a result of the false statement, either by direct diversion of sales from itself to defendant or by a lessening of the 22 goodwill associated with its products 23 24 25 26 3 Plaintiff’s fourth cause of action is for intentional interference. In their Motion, Defendants do not address this claim except to argue “if [the Lanham Act and the UCL/FAL] claims fail, so does 27 the interference claim.” (Def. Mot. at 14.) Because the Court herein finds that Defendants are not 1 Southland Sod Farms v. Stover Seed Co., 108 F.3d 1134, 1139 (9th Cir. 1997). 2 Claims pursuant to California Business and Professions Code section 17200 and 3 section 17500 are “substantially congruent” to claims made under the Lanham Act. 4 Cleary v. News Corp., 30 F.3d 1255, 1262–63 (9th Cir. 1994) (citing Academy of 5 Motion Picture Arts & Scis. v. Creative House Promotions, Inc., 944 F.2d 1446, 1457 6 (9th Cir. 1991)); JHP Pharm., Ltd. Liab. Co. v. Hospira, Inc., 52 F. Supp. 3d 992, 7 997 n.4 (C.D. Cal. 2014). 8 B. Literal Falsity 9 To meet the first element, statements can be “literally false, either on [their] 10 . . . face or by necessary implication,” or “literally true but likely to mislead or 11 confuse consumers.” Southland Sod Farms, 108 F.3d at 1139. When evaluating 12 whether a claim is literally false, it “must always be analyzed in its full context.” Id. 13 1. Ambiguity 14 Defendants argue the term “TSI only” is not literally false because it is 15 “ambiguous and undefined.” (Def. Mot. at 15); see Nutrition Distribution LLC v. 16 PEP Research, LLC, No. 16CV2328-WQH-BLM, 2019 WL 652391, at *4 (S.D. Cal. 17 Feb. 15, 2019) (“[O]nly an unambiguous message can be literally false.”); In re 18 Century 21-RE/MAX Real Estate Ad. Claims Litig., 882 F. Supp. 915, 923 (C.D. Cal. 19 1994) (same). “An advertisement is not literally false if consumers need extrinsic 20 information, assumptions, or inferences to reach the false conclusion.” Nutrition 21 Distribution LLC, 2019 WL 652391, at *4. 22 In support of this argument, Defendants point to the deposition of Plaintiff’s 23 expert Dr. Gupta, wherein she testified, “I’m not sure what you mean by TSI-only 24 and not TSI-only.” (Exhibit 17 to Declaration of Erik Haas, ECF No. 140-1, at 25 302:24–25.) But, an outside expert’s confusion on the definition of a term being used 26 at her deposition and out of context is not definitive. What is relevant is whether the 27 consumers would find the use of the term ambiguous. As noted above, Plaintiff is 1 contested phrase “TSI only.” Defendants do not point to an example of where they 2 used the phrase “TSI only” to consumers, let alone any evidence of consumers 3 finding the phrase to be confusing. This is especially true considering the consumers 4 are likely educated entities considering the phrase in context. Therefore, the Court 5 finds Defendants have not demonstrated that the phrase “TSI only” is ambiguous. 6 2. Whether the Statements Are False or Misleading 7 Defendants combat the assertion that their statements that IMMULITE detects 8 TSI only and does not detect TBI are false; Defendants argue that IMMULITE indeed 9 detects TSI and does not detect TBI. (Def. Mot. at 16.) Further, Defendants argue 10 the claims were always “made in conjunction with [the] statements regarding the 11 intended use (diagnosing Graves’ Disease) and [IMMULITE’s] performance data 12 (98% specificity).” (Id.) Defendants argue the claim is therefore literally true 13 because, when read in context, the claims were that “when used for its intended 14 purpose, IMMULITE could detect TSI only and help diagnose Graves’ Disease 15 accurately 98.5% of the time.” (Id.) Defendants argue this message is true because 16 IMMULITE “achieves excellent clinical specificity and clinical sensitivity.” (Id.) 17 As to the first, broader argument that the advertising is not false because 18 IMMULITE can detect TSI only, Plaintiff disagrees, arguing it is simply false to 19 claim that IMMULITE can detect “TSI only” as the assay is “incapable of detecting 20 stimulating antibodies only.” Plaintiff argues IMMULITE “can return false positives 21 due to detection of TBI.” (Pl. Opp’n at 13.)4 22 In the Ninth Circuit, literal falsity is a question of fact, and summary judgment 23 should not be granted where a reasonable jury could conclude a statement is not false. 24 25 4 In their Motion, Defendants strangely focus on Plaintiff’s product and its ability to detect TSI only. (Def. Mot. at 16–17.) While this argument might go to an unclean hands defense, it is 26 immaterial here. Whether or not Plaintiff’s advertising is false is not relevant when evaluating whether Defendants’ advertising is false. Indeed, both products were cleared by the FDA as a “TSI 27 assay” (id. at 17) but Plaintiff argues this is because Defendants’ FDA submission was false and 1 See Southland Sod Farms, 108 F.3d at 1144–45 (overturning grant of summary 2 judgment where a reasonable jury could determine advertisements were false based 3 on conflicting testimony). Here, the Court has been presented with conflicting expert 4 testimony as to whether IMMULITE actually detects TSI only. Plaintiff’s expert Dr. 5 Gupta opines that IMMULITE is unable to distinguish between TSI (also known as 6 TSAb) and TBI (also known as TBAb). (Exhibit 9 to Declaration of T. Kevin 7 Roosevelt, ECF No. 171, at 18.) Her opinion “refute[s] the claim of the Immulite 8 bridge assay as detecting only TSIs,” and she believes IMMULITE “is not specific 9 for TSI as claimed.” (Id. at 19, 23.) 10 Defendants retained Dr. Rapoport to opine whether Defendants’ statements 11 were false, deceptive, and/or material to the parties’ customers. (Exhibit 3 to 12 Declaration of Erik Haas, ECF No. 138-2.) In stark contrast to Dr. Gupta, Dr. 13 Rapoport concludes, “the statements made by Siemens at issue in this litigation are 14 not false, deceptive, or material to clinical laboratories’ purchasing decisions.” (Id. 15 at 2.) This is because IMMULITE “does not detect so-called blocking antibodies in 16 a clinically meaningful manner when used as indicated to aid in the diagnosis of 17 hyperthyroid Graves’ disease” and IMMULITE is properly referred to as a TSI assay. 18 (Id. at 2–3.) 19 As the Ninth Circuit has held, “[i]f the plaintiff’s evidence suggests that the 20 products do not work as advertised and the defendant’s evidence suggests the 21 opposite, there is a genuine dispute of material fact for the fact-finder to decide.” 22 Sonner v. Schwabe N. Am., Inc., 911 F.3d 989, 993 (9th Cir. 2018); see also, e.g., 23 Hansen Beverage Co. v. Vital Pharm., Inc., No. 08-CV-1545, 2010 WL 1734960, at 24 *8 (S.D. Cal. Apr. 27, 2010) (holding that both parties had “presented evidence from 25 which a reasonable juror could find by a preponderance of the evidence that each is 26 entitled to a verdict in its favor” and this demonstrated a genuine issue of material 27 fact as to whether the claim is literally false). Further, “[w]here the statements were 1 experience,” the court should consider that as part of the context in which the 2 statements were made. Kwan Software Eng’g, Inc. v. Foray Techs., LLC, No. C 12- 3 03762 SI, 2013 WL 244999, at *3 (N.D. Cal. Jan. 22, 2013), aff’d, 551 F. App’x 298 4 (9th Cir. 2013). Here, both sides offer competing expert testimony that involves 5 technical expertise and familiarity with the products. Both sides have evidence as to 6 whether the statements were false, especially considering the statements were made 7 to those knowledgeable in the field. Therefore, a material fact exists as to whether 8 the advertisements are “literally false, either on [their] face or by necessary 9 implication, or [whether the ads are] literally true but likely to mislead or confuse 10 consumers.” Southland Sod Farms, 108 F.3d at 1139; see also In re Apple Comp. 11 Sec. Litig., 886 F.2d 1109, 1117 (9th Cir. 1989) (“As a general rule, summary 12 judgment is inappropriate where an expert’s testimony supports the nonmoving 13 party’s case.”). 14 This finding is not changed by Defendants’ second argument that when the 15 “TSI only” statement is placed “in context” with IMMULITE’s specificity 16 information, the statement is true. There is still a material question of fact as to 17 whether the statement is true, no matter when and how it is said. 18 However, such a finding does not end the entire inquiry. Defendants next 19 argue that even if the statements are false, customers were not deceived. (Def. Mot. 20 at 17.) 21 C. Deception and Materiality 22 When a plaintiff has shown falsity, deception may be presumed if the 23 defendant intended to deceive customers. See William H. Morris Co. v. Grp. W. Inc., 24 66 F.3d 255, 258 (9th Cir. 1995). However, here, the Court finds Plaintiff has not 25 shown falsity and there is a material question of fact as to the issue. Therefore, the 26 issue is whether the advertisements actually deceived or had the tendency to deceive 27 a substantial segment of their audience. Rice v. Fox Broad. Co., 330 F.3d 1170, 1180 1 the purchasing decision.” Southland Sod Farms, 108 F.3d at 1139. 2 The parties dispute exactly who is in the relevant purchasing market that could 3 be deceived by the advertising, but they do not dispute that laboratories are at least a 4 part of the market. Therefore, the Court starts by analyzing any evidence of 5 deception of laboratories. 6 1. Laboratories 7 It is undisputed that two laboratories (Sonic/CPL and LabCorp) switched from 8 using Thyretain to using IMMULITE. But Defendants argue the evidence shows 9 that the laboratories switched not because of the advertising, but simply because 10 IMMULITE was proven to be better. Indeed, as mentioned above, deception must 11 be material. Further, “[i]n a suit for damages under section 43(a), . . . actual evidence 12 of some injury resulting from the deception is an essential element of the plaintiff’s 13 case.” Harper House, Inc. v. Thomas Nelson, Inc., 889 F.2d 197, 210 (9th Cir. 1989). 14 If the advertisements did not influence the customers’ decision, then there is no false 15 advertising claim. See BMMG, Inc. v. Am. Telecast Corp., 42 F.3d 1398 (9th Cir. 16 1994) (holding the plaintiff must “link the loss of sales to the alleged deception”). 17 When the FDA cleared IMMULITE, it approved a package insert for the 18 product. Defendants sent out this package insert, the Instructions for Use (“IFU”), 19 and relevant documents to potential customers. The IFUs were given to customers 20 and posted on a document library so customers can access them at any time. (Exhibit 21 T to Declaration of T. Kevin Roosevelt, ECF No. 147-3, at 208:6–12.) It is Plaintiff’s 22 position that the IFU itself, along with Defendants’ advertising of the assay through 23 press releases and websites, contain Defendants’ false statements. The IFU does 24 refer to IMMULITE as a TSI only assay, but Defendants argue that even if it can be 25 proven that this is false, advertising the product in this way did not deceive 26 customers. 27 Defendants point to the depositions of two laboratory representatives. First, 1 IMMULITE assay once it was cleared by the FDA. (Exhibit 24 to Declaration of 2 Erik Haas, ECF No. 140-2, at 225:1–3.) “The possibility of adopting the IMMULITE 3 TSI assay was a decision that started within CPL” because CPL wanted an assay that 4 was “in general, an improvement” over Thyretain. (Id. at 226:11–19.) The decision 5 about whether or not to adopt the assay “involved months of discussion and 6 deliberation at CPL.” (Id. at 234:18–21.) 7 Once the assay was cleared, CPL began evaluating the assay, which “involved 8 a review of the relevant literature, such as the IFU and other information from the 9 manufacturer.” (Id. at 225:4–6.) CPL also conducted “a validation study” after FDA 10 approval. (Id. at 225:4–6.) CPL does validation studies for all potential new assays, 11 and the study for IMMULITE was signed off by multiple people within CPL. (Id. at 12 225:11–21.) The approval process is a “layered” one, requiring the approval of “a 13 scientific doctor, the technical director, a pathologist, and a laboratory director.” (Id. 14 at 226:2–5.) The validation process proved to CPL that IMMULITE “performed 15 comparably [to Thyretain] and conformed to [CPL’s] validation protocol and 16 acceptance criteria.” (Id. at 227:10–11.) Ultimately, CPL concluded that 17 IMMULITE “was a superior assay for use in the laboratory.” (Id. at 227:21–228:1.)5 18 IMMULITE had higher sensitivity, specificity, and stability “vis-à-vis the 19 proficiency testing, the staff productivity, [and] the turnaround time.” (Id. at 134: 20 21–24.) 21 Mr. Silberman further testified he did not recall seeing any press releases about 22 IMMULITE, and while the press releases may have made it to the laboratory, he is 23 “usually reading IFUs and manufacturer notifications.” (Id. at 232:16–233:6.) He 24 does not believe that any of Defendants’ press releases had any impact on the lab’s 25 decision to assess and validate IMMULITE. (Id. at 233:12–14.) Prior to the adoption 26 of IMMULITE, Silberman did not review statements on Defendants’ website about 27 1 the assay, and does not remember going on Defendants’ website. (Id. at 233:15–25.) 2 CPL “is not guided by manufactures’ sales and marketing collaterals on a website.” 3 (Id. at 223:1–3.) 4 LabCorp’s representative Andre Valcour was also deposed, and he testified 5 that it was “not true” that LabCorp made its decision to switch products based on 6 marketing material. (Exhibit 30 to Declaration of Erik Haas, ECF No. 140-2, at 7 249:2–7.) He testified to LabCorp’s protocol when it is provided information about 8 a test like IMMULITE. After receiving information on IMMULITE, he applied his 9 usual “analytic evaluation” for the assay. (Id. at 57:16–17.) In this evaluation, he 10 reviews all material about the product, which of course includes IFUs and other 11 information from vendors. He and several others do “very thorough reviews of the 12 literature.” (Id. at 56:23–57:1.) He testified that he understands that when vendors 13 give him papers regarding the product, “they’re likely to provide [him] only papers 14 that are positive for their test.” (Id. at 55:12–15.) He reviews the vendor’s data to 15 “make sure that there’s no evidence of either intentional or unintentional biases in 16 the study.” (Id. at 55:16–21.) He considers it his “duty . . to try to understand every 17 aspect of the test that [he’s] offering and all the potential weaknesses and strengths.” 18 (Id. at 56:13–19.) Specifically, here, he testified he reviewed a paper written by 19 Siemens entitled Clinical Evaluation of IMMULITE 2000 TSI assay “which is 20 essentially a summary of the FDA submission.” He also reviewed the “FDA 21 accepted” manufacturer’s package insert for IMMULITE. (Id. at 53:1–10.) Because 22 the FDA is “incredibly rigorous in their vetting of the data[,]” he typically weighs 23 the FDA submission highest of all the documents. (Id. at 55:25–56:4.) 24 In sum, he finds this lawsuit to be “frivolous” because it assumes that LabCorp 25 doesn’t “do a very, very rigorous job of vetting our assays and that we can be swayed 26 by marketing.” (Id. at 91:14–21.) He finds Plaintiff’s suggestion in this suit 27 “personally offensive” because LabCorp does a “rigorous job and . . . [doesn’t] get 1 Before that week, Mr. Valcour had not heard of the IMMULITE assay being referred 2 to as a “TSI only” assay. (Id. at 96:20–22.) 3 In analyzing Mr. Silberman’s and Mr. Valcour’s testimony, Defendants focus 4 on the laboratories’ access to the press releases and Defendants’ website. But 5 whether or not laboratory representatives saw press releases or websites is not 6 necessarily dispositive because the issue is whether they saw and were likely 7 influenced by the false advertising. The allegedly false statements at issue existed in 8 more places than press releases. It is not disputed that the customers were in 9 possession of the IFUs and other documents sent by Defendants, which Plaintiff 10 claims contain false statements. Mr. Silberman testified, “the official client bulletin, 11 the IFU regarding overall sensitivity and specificity of our analytic methods . . . are 12 sort of the dominant documents on which we predicate a lot of our decision to move 13 forward.” (Exhibit EE to Declaration of T. Kevin Roosevelt, ECF No. 147-5, at 14 125:19–24.) In context, this appears to mean that he begins by reading documents 15 provided by the manufacturers, and then proceeds into the validation study and other 16 evaluation methods discussed above. 17 However, simply because the laboratories reviewed the allegedly false 18 statements in the package inserts and document library does not mean the statements 19 had any material impact on their decision-making process. In Appliance Recycling 20 Centers of America, Inc. v. JACO Environmental, Inc., 378 F. App’x 652, 655 (9th 21 Cir. 2010), the Ninth Circuit held the allegedly false statement of “patent pending” 22 was not material to three utilities’ decision-making process when “three utility 23 officials testified that the ‘patent pending’ status . . . was not relevant to their utility’s 24 decision.” Here, Defendants have submitted similar information as to that in 25 Appliance Recycling; the lab representatives’ testimonies show the alleged false 26 statements were not material to their decision to switch products. And Plaintiff has 27 not presented any conflicting evidence of materiality or evidence that the laboratories 1 Quattrocchi, 673 F.3d 1105, 1110 (9th Cir. 2012) (holding materiality “is ‘typically’ 2 proven through consumer surveys,” but surveys are not required, and materiality can 3 also be proven when the plaintiff presents “direct evidence that [the challenged] 4 statements were likely to influence consumer’s purchasing decisions”); U.S. Rubber 5 Recycling, Inc. v. Ecore Int’l, CV 09-9516 SJO (OPx), 2011 WL 13130696, at *6 6 (C.D. Cal. Dec. 12, 2011) (finding the plaintiff had not presented a triable issue of 7 fact as to whether the false marketing caused plaintiff to lose sales when plaintiff did 8 not have “testimony from a single consumer stating that Defendant’s claim . . . 9 influenced its decision not to buy Plaintiff’s products”). 10 Plaintiff makes two arguments as to why the advertising is material. Plaintiff 11 first argues the customers must have been deceived because the labs now believe that 12 IMMULITE detects TSI only, and now repeat the allegedly false assertions on their 13 website and marketing. (Pl. Opp’n at 19.) But simply because the customers have 14 the same beliefs as Defendants about the product does not mean they were deceived. 15 As noted above, they could have formed these beliefs in a number of ways—for 16 example, their own internal validation and testing procedures. Second, Plaintiff 17 argues that because the statement “TSI only” concerns the “inherent quality or 18 characteristic” of the product, it is material. See Pom Wonderful LLC v. Purely Juice, 19 Inc., No. CV-07-2633 CAS (JWJx), 2008 WL 4222045, at *11 (C.D. Cal. July 17, 20 2008) (“The fact that Purely Juice’s false advertising pertained to the very nature of 21 its juice product establishes its materiality.” (citing Johnson & Johnson Vision Care, 22 Inc. v. 1–800 Contacts, Inc., 299 F.3d 1242 (11th Cir. 2002))). The Court disagrees 23 with this finding of Pom Wonderful that if the false advertising relates to an important 24 quality of the product, it is naturally material. Instead, the Court follows the Ninth 25 Circuit’s materiality test, which asks whether the statement is likely to influence the 26 purchasing decision. No matter what the false advertising pertains to, if the customer 27 is not likely to be influenced by the statement, it is not material. 1 conclusion to use IMMULITE after their own sophisticated processes, and any false 2 advertising was not material to their decisions. The Court finds there is no dispute 3 of fact as to the issue of deceit of the laboratories. Because Plaintiff cannot prove its 4 claims as to the laboratories, the Court GRANTS Defendants’ Motion for Summary 5 Judgment for claims of false advertising and unfair competition as it relates to the 6 laboratories. 7 2. Physicians 8 Again, the inquiry does not end here. Quidel says the relevant market is not 9 comprised of only laboratories, but also physicians, as they are the ones who “drive 10 demand for the assays” and they too were deceived by the false statements. (Pl. 11 Opp’n at 16.) The first issue is therefore whether the physicians are even in the 12 relevant purchasing market. In Coastal Abstract Service, Inc. v. First American Title 13 Insurance Co., 173 F.3d 725, 735 (9th Cir. 1999), the Ninth Circuit approved a jury 14 instruction related to the definition of the relevant purchasing public. Courts have 15 interpreted this to mean, “[d]efining the relevant purchasing public is a task for the 16 jury.” Gonzalez v. Allstate Ins. Co., No. CV 04-1548 FMC (PJWx), 2005 WL 17 5891935, at *9 (C.D. Cal. Aug. 2, 2005). 18 This Court agrees and finds that both sides have presented evidence as to 19 whether physicians are in the relevant market for the assays. Specifically, Quidel 20 points to the deposition of Defendants’ employee, Carole Dauscher. Ms. Dauscher 21 testified that Defendants previously contracted a marketing agency to conduct a 22 marketing campaign aimed at clinicians. (Exhibit 36 to Declaration of T. Kevin 23 Roosevelt, ECF No. 171-1, at 106:1–9.) According to Ms. Dauscher, the agency 24 marketed to physicians as opposed to laboratories because “it’s really important to 25 educate the physicians . . . [b]ecause if they don’t order the test, then there’s . . . no 26 point of having it in the laboratory.” (Id. at 106:15–25.) Physicians were not the 27 ones buying the assays, but through the marketing they became informed of the test, 1 information. (Id. at 107:1–6; 108: 18–23.) Further, Dr. Silberman, a director of 2 Sonic/CPL laboratory testified that the clinicians are “substantially” in charge of 3 deciding which type of assay to run. (Exhibit 3 of ECF No 177, at 117:14–22.) He 4 testified the clinicians “have the capability of and ask for [the assay] by name . . . 5 and in some circumstances they will specify.” (Id.) Finally, a Siemens representative 6 received an email from a doctor who asked if IMMULITE “is specific to TSI or if it 7 potentially can detect TBI’s directed towards the N-terminal part of the thyroid 8 receptor.” (Exhibit 18 to Declaration of T. Kevin Roosevelt, ECF No. 171.) This 9 shows the physicians are aware of the details of the test, and therefore may be 10 interested in how the product is marketed. 11 But Defendants point to another one of Quidel’s experts, who states that at her 12 institution, “when a TSI is ordered [by a clinician], there is no indication on the report 13 of which assay (Roche, Thyretain, Immulite, etc.) was utilized” and the physician 14 only receives the results from the test, i.e. the measurement of TSI. (Exhibit 51 to 15 Declaration of Erik Haas, ECF No. 140-2, at 9.) 16 Therefore, there is a dispute of material facts as to whether physicians are part 17 of the relevant market of purchasers of the assays. If the jury finds that the physicians 18 are part of the relevant market, then the issue will become whether the physicians 19 were deceived or likely to be deceived. And even if the Court were to assume the 20 jury would find the physicians to be part of the market, the Court finds there is a 21 dispute of material fact as to whether the physicians were or are likely to be deceived. 22 Plaintiff’s expert conducted a survey and determined that a substantial portion of 23 physicians were deceived by Defendants’ statements. (“Ezell Report,” Exhibit 12 to 24 Declaration of Erik Haas, ECF 135-3, at ¶ 7.) This creates a dispute of fact as to the 25 issue of deception of physicians. 26 The Court DENIES Defendants’ motion for summary judgment as it relates 27 to the physicians 1 D. Unclean Hands 2 In an alternative argument, Defendants argue that none of the above matters 3 because Plaintiff’s claims are entirely barred by the unclean hands defense. 4 “Unclean hands is a defense to a Lanham Act infringement suit.” Japan 5 Telecom, Inc. v. Japan Telecom Am. Inc., 287 F.3d 866, 870 (9th Cir. 2002) (quoting 6 Fuddruckers, Inc. v. Doc’s B.R. Others, Inc., 826 F.2d 837, 847 (9th Cir. 1987)); see 7 Emco, Inc. v. Obst, No. CV03-6432-R(RZX), 2004 WL 1737355, at *4 (C.D. Cal. 8 May 7, 2004) (applying the unclean hands defense to a Lanham Act false advertising 9 claim).6 The doctrine of unclean hands “demands that a plaintiff act fairly in the 10 matter for which he seeks a remedy. He must come into court with clean hands, and 11 keep them clean, or he will be denied relief, regardless of the merits of his claim.” 12 Kendall-Jackson Winery, Ltd. v. Superior Court, 76 Cal. App. 4th 970, 978 (Ct. App. 13 1999) (citing Precision Co. v. Automotive Co., 324 U.S. 806, 814–15 (1945); and 14 Hall v. Wright, 240 F.2d 787, 794–95 (9th Cir. 1957)). To prevail on a defense of 15 unclean hands, a defendant must demonstrate by clear and convincing evidence: (1) 16 “that the plaintiff’s conduct is inequitable;” and (2) “that the conduct relates to the 17 subject matter of [the plaintiff’s] claims.” Fuddruckers, 826 F.2d at 847. Whether 18 the doctrine of unclean hands applies is a question of fact. CrossTalk Prods., Inc. v. 19 Jacobson, 65 Cal. App. 4th 631, 639 (Ct. App. 1998). 20 Specifically, Defendants argue that Plaintiff’s conduct was inequitable for two 21 reasons: first, because Plaintiff “engage[s] in the very advertising it alleged is false 22 and misleading.” (Def. Mot. at 24.) This is because Thyretain also detects TBI and 23 6 A few courts have held, “[u]nlike a Lanham Act claim, the unclean hands doctrine is not available 24 as a defense to bar claims for unfair business practices act violations under Cal. Bus. & Prof. Code 25 § 17200 et seq.” Certified Nutraceuticals, Inc. v. Avicenna Nutraceutical, LLC, No. 3:16cv02810- BEN-BGS, 2018 WL 3618243, at *5 (S.D. Cal. July 30, 2018); see also Cyclone USA, Inc. v. LL&C 26 Dealer Servs., LLC, No. 03-992 AJW, 2007 WL 9662337, at *14 (C.D. Cal. Nov. 8, 2007) (finding the defendant “has not shown that unclean hands is a defense that may be asserted in response to a 27 claim brought under state unfair competition law”). The reasoning behind these decisions is 1 the evidence shows “when TBI is present in a patient’s sample, it may bind to 2 Thyretain’s receptor, interfere with Thyretain’s measurement of TSI, and result in a 3 false ‘negative’ reading.” (Id.) And second, Defendants argue Plaintiff “engaged in 4 an illicit reimbursement scheme.” (Id. at 24.) 5 Turning to the first allegation, to resolve whether Plaintiff engaged in false 6 advertising, the Court must conduct the same analysis it conducted above for 7 Defendants’ assay. That is, the Court must determine whether it is “literally false” 8 for Plaintiff to call Thyretain a TSI assay. And the same result above applies here— 9 there is evidence on both sides of this argument, so a genuine issue of material fact 10 exists. Dr. Rapoport opines that Quidel has misrepresented the performance of 11 Thyretain. (Exhibit 3 to Declaration of Erik Haas, ECF No. 138-2, at 2.) “Quidel’s 12 stated belief that [Thyretain’s] chimeric receptor ‘sees’ ‘only’ TSI is incorrect.” (Id. 13 at 3.) In contrast, Dr. Gupta opines that Thyretain “measures [TSI] by its ability to 14 bind and activate TSHR leading to production of thyroid hormones and 15 hyperthyroidism hence it is specific for stimulating antibody and can distinguish 16 between stimulating and blocking activities.” (Exhibit 9 to Declaration of T. Kevin 17 Roosevelt, ECF No. 171, at 18.) Given this dispute of material fact, the Court cannot 18 determine at this stage whether Plaintiff’s advertising is false; therefore, the Court 19 cannot determine whether Plaintiff has unclean hands due to its advertising of 20 Thyretain as a “TSI only assay.” 21 Turning to Defendants’ second unclean hands theory, Defendants allege 22 Plaintiff engaged in an “illicit reimbursement scheme” by telling customers to use 23 the wrong Current Procedural Terminology (“CPT”) billing code to submit 24 reimbursement claims for Thyretain. (Def. Mot. at 9, 24.) Defendant argues this 25 allowed Plaintiff to charge an inflated price for Thyretain. In response, Plaintiff 26 argues that this allegation is not at all related to its claims against Defendants and 27 therefore cannot form an unclean hands defense. (Opp’n at 25.) Indeed, the unclean 1 unrelated to the claim to which it is asserted as a defense.” Republic Molding Corp. 2 v. B.W. Photo Utils., 319 F.2d 347, 349 (9th Cir. 1963). It can only be applied “where 3 some unconscionable act of one coming for relief has immediate and necessary 4 relation to the equity that he seeks in respect of the matter in litigation.” 5 TrafficSchool.com, Inc. v. Edriver, Inc., 633 F. Supp. 2d 1063, 1084 (C.D. Cal. 6 2008). Because the Court grants judgment as to Plaintiff’s claims regarding the 7 laboratories in this Order, Defendants’ unclean hands claim no longer is related to 8 the claims at issue. Defendants claim Plaintiff told laboratories to use the wrong 9 billing code, and thus profited more than it should have. This defense is not 10 sufficiently related to what is left of Plaintiff’s case after this Order.7 This is 11 especially true considering Defendants’ timeline of the alleged scheme (and whether 12 it overlaps with the present suit) is unclear, and “past misconduct cannot form the 13 basis for an unclean hands defense: ‘Plaintiff’s position must be judged by the facts 14 existing as they were when suit was begun, not by the facts existing in an earlier 15 time.’” Pom Wonderful LLC v. Welch Foods, Inc., 737 F. Supp. 2d 1105, 1109 (C.D. 16 Cal. 2010) (quoting 6 McCarthy on Trademarks and Unfair Competition § 31:48 (4th 17 ed. 2010)). 18 The Court DENIES Defendants’ motion for summary judgment based on the 19 unclean hands defense. 20 21 22 7 And even if it were to be determined that Defendants’ unclean hands defense was sufficiently 23 related to the rights Plaintiff asserts, a court “must not automatically apply the doctrine of unclean hands and ‘permit a defendant wrongdoer to retain the profits of his wrongdoing merely because 24 the plaintiff himself is possibly guilty of transgressing the law.’” POM Wonderful LLC v. Coca 25 Cola Co., 166 F. Supp. 3d 1085, 1092 (C.D. Cal. 2016) (quoting Johnson v. Yellow Cab Transit Co., 321 U.S. 383, 387 (1944)). “Rather, determining whether the doctrine of unclean hands 26 precludes relief requires balancing the alleged wrongdoing of the plaintiff against that of the defendant, and ‘weigh[ing] the substance of the right asserted by [the] plaintiff against the 27 transgression which, it is contended, serves to foreclose that right.’” Northbay Wellness Grp., Inc. 1 E.

It denies the 4 remainder of the Motion. 5 PLAINTIFF’S MOTION FOR SUMMARY JUDGMENT 6 Plaintiff moves for summary judgment solely on the element of falsity. 7 || Plaintiff argues it has demonstrated the falsity of Defendants’ statements. The same 8 ||statements are at issue here as in Defendants’ Motion: the IMMULITE detects TSI 9 || only; that IMMULITE is not like a TRAD assay; and that IMMULITE does not detect 10 || TBI. (PI. Mot. at 15-17.) As is likely evident at this point, the Court finds a genuine 11 |/issue of material fact for this element.
