OPINION
In NFL Properties LLC v. All Authentic Corp. (“NFL Action”), NFL Properties sued All Authentic for allegedly selling counterfeit National Football League jerseys. The plaintiff here, Hudson Insurance Company, defended All Authentic in the NFL Action under its insurance policy with All Authentic. The defendant, Colony Insurance Company, however, argued that its policy did not cover the claims that NFL Properties brought against All Authеntic and refused to defend the suit.
In this diversity action, Hudson seeks equitable contribution from Colony for Hudson’s costs of defending All Authentic in the NFL Action. The district court correctly granted Hudson’s motion for summary judgment: Hudson is entitled to equitable contribution because Colony had a duty to defend All Authentic but failed to do so. The NFL Properties complaint allegеd facts showing that All Authentic was potentially liable for slogan infringement, a claim covered by the Colony insurance policy. We have jurisdiction under 28 U.S.C. § 1291 and affirm.

NFL Properties LLC sued All Authentic Corporation for damages in the Southern District of New York. The complaint (“NFL complaint”) essentially accused All Authentic of making and selling counterfeit NFL jerseys. The complaint listed several specific causes of action for trademark infringement, trademark counterfeiting, trademark dilution, unfair competition, and deceptive acts and practices.
There are several paragraphs of the NFL complaint that are particularly relevant here. Paragraрh 18 states that All Authentic offered a counterfeit “Steel Curtain Custom Limited Edition Steelers Jersey” on All Authentic’s website. Paragraph 18 further states:
The Counterfeit Jersey reads “Steel Curtain” across the back and bears the numbers of four Pittsburgh Steelers players using the same style of numbering and lettering as appears on the authentic Pittsburgh Steelers’ NFL Uni *1266 form Design Jerseys. The Steеlers have strong common law rights in the mark “Steel Curtain” and own a state registration for the mark “Steel Curtain ... Pittsburgh Steelers.” The Counterfeit Jersey features the same black and gold color combination and striping as the official Pittsburgh Steelers’ NFL Uniform Design Jerseys.
(Emphasis added).
The NFL complaint further alleges that: [Plaintiff] NFL Properties is jointly owned in equal shares by the Member Clubs of the NFL. NFL Properties has been licensed to use the trademarks of the Member Clubs for commercial purposes and is the exclusive trademark enforcement arm for the Member Clubs. In these capacities, NFL Properties promotes the intellectual property of the NFL and the Member Clubs in their commercial activities and protects the marks owned by the Member Clubs against misuse in various forms.
(Emphasis added). Finally, the complaint states that All Authentic “has not been granted permission or authorization by NFL Properties, the NFL or its Member Clubs to use any NFL Marks in connection with jerseys.”
All Authentic tendered the NFL Action to two insurance companies whose policies it held: Colony and Hudson. Colony sent a letter denying that it had a duty to defend or indemnify All Authentic in the NFL Action. Hudson, on the other hand, advised All Authentic that it would defend the NFL Aсtion under a reservation of rights.
In relevant part, the Colony insurance policy covered “personal and advertising injury,” defined as “injury ... arising out of [the offense of] ... [infringing upon another’s copyright, trade dress or slogan in your ‘advertisement.’ ” The Colony policy contained an exclusion providing that the policy did not apply to “ ‘Personal and advertising injury’ arising out of the infringement of copyright, patent, trademark, trade secret or other intellectual property rights. However, this exclusion does not apply to infringement, in your ‘advertisement,’ of copyright, trade dress or slogan.” 1
Hudson defended All Authentic in the NFL Action, incurring defense costs in excess of $900,000. The NFL Action ultimately settled. In Nоvember 2007, Hudson initiated this action against Colony for equitable contribution for 50% of its defense fees and costs incurred in the defense of All Authentic. 2 Hudson’s complaint argues that Colony should have defended All Authentic in the NFL Action because “[b]ased on the allegations in the NFL Action, All Authentic faced potentially covered liability for trade dress infringement and slogan infringement in All Authentic’s advertisements.” The district court granted Hudson’s motion for partial summary judgment, concluding that “by alleging that the insured infringed ‘Steel Curtain,’ the [NFL complaint] set forth a claim for slogan infringement that was potentially covered by the Colony Policy.” Colony appeals this ruling.

We review a grant of summary judgment de novo.
Anthem Elecs., Inc. v. Pac. Employers Ins. Co.,

An action for equitable contribution allows an insurer to sue for pro rata reimbursement from another insurance company when it has defended a mutually insured party without participаtion by the other insurance company.
See Monticello Ins. Co. v. Essex Ins. Co.,
If a potential cause of action is shown for one covered claim, Colony had a duty to defend All Authentic as to all claims in the NFL Action, regardless of whether the other claims were covered under the policy.
See CNA Cas. of Cal. v. Seaboard Sur. Co.,
Colony faces an uphill battle from the beginning because the duty to defend in California is extensive. “[A] liability insurer owes a broad duty to defend its insured against claims that create a potential for indemnity.... [T]he carrier must defend a suit which
potentially
seeks damages within the coverage of the policy.”
Montrose Chem. Corp. of Cal. v. Superior Court,
A
Colony first argues that the district court should be reversed because “[n]o such claim [of slogan infringement] was made in the complaint and California law precludes a court or insured from speculating about unpled claims to manufacture a potential for coverage.” This argument fails because under California law “the insurer’s duty is not measured by the technical legal cause of action pleaded in the underlying third party complaint, but rather by the
potential
for liability under the policy’s coverage as revealed by the
facts
alleged in the complaint or otherwise known to the insurer.”
CNA,
Colony argues that the Gunderson line of narrow “speculation” cases supports its argument that the NFL сomplaint did not potentially state a cause of action for slogan infringement. These cases do not support Colony’s argument. These cases *1268 concluded that there was no potential for coverage, not because the complaint did not list a particular legal cause of action, but because the complaint did not allege any facts supporting a covered cause of action. 4
The lead “speculation case,”
Gunderson v. Fire Insurance Exchange,
Here, in contrast, the facts alleged in the NFL complaint state that All Authentic sold a “Steel Curtain Limited Edition Steelers Jersey” on its website, which “reads ‘Steel Curtain’ across the back and bears the numbers of four Pittsburgh Steelers players.” As the district court noted, “A fair reading of the [NFL complaint] reveals that ‘Steel Curtain’ is used to promote fan loyalty to the Steelers (an NFL Member Club) in general, and a subset of Steeler players in particular.” The district court concluded that this potentially stated a claim for slogan infringement because a “slogan” is a “brief attention-getting phrase used in advertising or promotion.” (Quoting
Palmer v. Truck Ins. Exch.,
The Sixth Circuit has also addressed this question.

In
Cincinnati Insurance Co. v. Zen Design Group, Ltd.,
the Sixth Circuit concluded that the underlying complaint potеntially stated an action for slogan infringement because the complaint stated that the third-party plaintiff “marketed and advertised its LED handheld flashlights using the widely-recognized trademarks ‘WEARABLE LIGHT’ and ‘SAPPHIRE.’ ”
B
Colony next argues that this Court should not find potential liability for slogan infringement because NFL Properties and its “powerhouse international law firm” must have consciously “chose[n] not to advance [NFL Properties’] claim for slogan infringement, which [they were] clearly aware of.” There is no merit for this “election” or “conscious avoidance” theory in the case law. Colony points out that in
Microtec Research, Inc. v. Nationwide Mutual Insurance Co.,
Contrary to Colony’s assertion, however,
Microtec
does not “stand[ ] for the principle that where the plaintiff acknowledges the existence of facts that could give rise to a cause of action but consciously avoids asserting that cause of action,” there is no duty to defend. Rather, we relied once again on thе absence of any
factual
allegations in the complaint.
See Microtec,

Finally, Colony argues that even if the NFL complaint stated a potential slogan infringement claim, “the NFL disclaimed any rights to that slogan in its complaint and thus could not have pursued a claim for slogan infringement.” “Thus,” Colony exclaims, “the District Court imposed a duty to defend based on the existence of a possible claim that, as plead[ed], could not be brought as a matter of law!” According to Colony, the facts in the complaint fail to allege ownership of the “Steel Curtain” slogan or that NFL Properties had standing to enforce the slogan rights.
California courts have cast doubt on the notion that a complaint must support all elements of a cause of action to state potential liability.
CNA Casualty
rejected the argument that there was no coverage
*1270
for a potential malicious prosecution claim even though it was clear that the malicious prosecution claim could not be brought because an essential element was missing (prior termination of the earlier proceeding in favor of the party alleging malicious prosecution).
See CNA,
Indeed, in cases where a complaint alleges facts that support a duty to defend, California courts have concluded that there is no duty to defend only when the third-party complaint unambiguously disclaims or concedes an element.
See Low v. Golden Eagle Ins. Co.,
However, NFL Properties did not unambiguously concede in its complaint that it had no standing to bring a slogan infringement claim for “Steel Curtain,” and NFL Properties did not expressly disclaim a slogan infringement claim or standing to bring such a claim. The NFL Complaint states that “NFL Properties is jointly owned in equal shares by the Member Clubs of the NFL.... NFL Properties promotes the intellectual property of the NFL and the Member Clubs ... and protects the marks owned by the Member Clubs against misuse in various forms.” Then the complaint states that “[t]he Steelers [an NFL Membеr Club] have strong common law rights in the mark ‘Steel Curtain.’ ”
Rather than unambiguously conceding the element of ownership or disclaiming standing, these statements argue that NFL Properties
does
have standing to enforce the Steelers’ rights to the phrase “Steel Curtain.” Because any ambiguity in the complaint or doubt regarding the duty to defend must be resolved in favor of coverage,
Montrose,
We reject Colony’s arguments on appeal. The district court correctly concluded there was a duty to defend based on a potential slogan infringement claim. Because the NFL complaint potentially stated a сause of action for slogan infringement, Colony had a duty to defend All Authentic in the NFL Action, and Hudson is entitled to equitable contribution.
AFFIRMED.
Notes
. Hudson's policy covered "advertising injury.” including "[infringement of copyright, title or slogan,” but did not contain a trademark exclusion.
. Hudson also had an equitable subrogation claim that was not at issue in the motion for summary judgment and is not at issue here.
. Because we conclude that the NFL complaint potentially supported a claim for slogan infringement, we need not address Hudson’s alternative argument that the NFL complaint also potentially supported a claim for trade dress infringement.

. The Sixth Circuit applied Michigan law, but California law and Michigan law do not appear to materially differ on this matter, and both parties discuss Zen Design as persuasive authority.
