OPINION
Plaintiff-Appellant Cincinnati Insurance Company (“Cincinnati”) brought an action for declaratory judgment against Defendants-Appellees Zen Design Group, Ltd. (“Zen Design”) and Sun Yu (‘Yu”), the president and owner of Zen Design (collectively “Zen”). Although Zen was a holder of a business insurance policy from Cincinnati, Cincinnati argued that it had no duty to defend or indemnify Zen in a suit brought against Zen by Armament Systems and Procedures, Inc. (“ASP”) alleg *548 ing, among other things, trademark and trade dress infringement. Both parties filed motions for summary judgment: Cincinnati desired a declaration that it had no duty to defend under its policy on any of ASP’s claims, while Zen sought for Cincinnati to assume the defense of the ASP action. Because nearly all of ASP’s claims against Zen were not covered under the policy, except for the possible claim of alleged infringement of slogan, the district court granted Cincinnati’s summary judgment motion on indemnification for all claims other than the infringement of slogan claim. However, the district court granted Zen’s motion for partial summary judgment because Zen’s policy with Cincinnati covered infringement of slogan actions and one of ASP’s claims against Zen possibly raised an infringement of slogan claim thus triggering Cincinnati’s duty to defend. Cincinnati timely appealed the district court’s decision.
On appeal, Cincinnati argues that the district court erred in its determination that Cincinnati had an obligation to defend the ASP action. Cincinnati asserts that the phrase “The Wearable Light” 1 was not a slogan but was another name for ASP’s light emitting diode (“LED”). In response, Zen argues that three of ASP’s claims against it activate the coverage provisions of the policy, namely, infringement of slogan, misappropriation of advertising idea or style of doing business, and disparagement. We AFFIRM the district court’s decision to grant Zen’s partial summary judgment motion declaring that Cincinnati has a duty to defend on the infringement of slogan claim and thereby has a duty to defend the whole ASP case. 2
I. JURISDICTION
The district court had jurisdiction based on diversity of citizenship pursuant to 28 U.S.C. § 1332. Zen Design is a Michigan corporation with its principal place of business in Michigan, and Yu is a Michigan resident. Cincinnati is an Ohio insurance corporation with its principal place of business in Ohio. “In actions seeking declaratory or injunctive relief, it is well established that the amount in controversy is measured by the value of the object of the litigation.”
Hunt v. Washington State Apple Adver. Comm’n,
Courts of appeals have jurisdiction pursuant to 28 U.S.C. § 1291, “when an appeal is taken from a final decision of the district court.”
Williams v. Kentucky,
II. BACKGROUND
Zen is in the business of designing han-dheld LED lighting devices. One of Zen’s signature creations is the Starlight™ flashlight. These devices are “small flashlights designed to provide illumination in a variety of situations where light is needed quickly and easily.” Appellees’ Br. at 12. This flashlight was designed “to have features distinct from other flashlights, such as shape, materials used, and overall appearance.” J.A. at 380 (Yu’s Declaration).
From December 13, 1999 through December 13, 2002, Zen had a Businessown-ers Package Policy (the “policy”) provided by Cincinnati. The terms of the policy cover business liability and provide Zen with coverage for “those sums that the insured becomes legally obligated to pay as damages because of ... ‘advertising injury’ to which this insurance applies.” J.A. at 51 (Compl., Attach.2). Cincinnati has “the right and duty to defend the insured against any ‘suit’ seeking those damages.” Id. The policy states that the coverage extends to an advertising injury “caused by an offense committed in the course of advertising your goods, products or services.” Id. In the definitions section “advertising injury” is defined as any injury arising out of:
a. Oral or written publication of material that slanders or libels a person or organization or disparages a person’s or organization’s goods, products or services;
c. Misappropriation of advertising ideas or style of doing business; or
d. Infringement of copyright, title or slogan.
*550 J.A. at 64 (Compl., Attach.2). In addition, the policy defines “advertising” as “an advertisement, publicity article, broadcast or telecast.” Id.
On September 14, 2000, ASP, a competitor of Zen, sued Zen and several other parties. ASP’s complaint stated causes of action for: (1) trade dress infringement under 15 U.S.C. § 1125(a); (2) trademark infringement under 15 U.S.C. § 1114(l)(a); (3) unfair competition under 15 U.S.C. § 1125(a); (4) dilution under 15 U.S.C. § 1125(c); (5) common law unfair competition, and (6) violation of Wisconsin’s Fraudulent Representations Act. In the complaint, brought in federal district court in Wisconsin, ASP asserted that it marketed and advertised its LED handheld flashlights using the widely-recognized trademarks “WEARABLE LIGHT” and “SAPPHIRE.” J.A. at 133 (ASP Compl. ¶ 11). ASP not only claimed that Zen and others infringed on these trademarks but also asserted that Zen copied the shape and trade dress of its handheld flashlights in order to capitalize on ASP’s name and business good will.
In October 2000, Zen tendered the defense of this action to Cincinnati and Cincinnati denied its responsibility for defense and indemnification coverage. In a response letter to Zen, Cincinnati cited this court’s opinion in
Advance Watch Co. v. Kemper National Insurance Co.,
Before the district court, Zen’s primary argument was that because ASP’s action raised an advertising injury based on misappropriation of advertising ideas or style of doing business, Cincinnati was "obligated to defend the action and indemnify Zen for any damages awarded. Zen also relied on two other injuries contained in the ASP complaint, disparagement and infringement of slogan, as justification for requiring Cincinnati to provide a defense. Cincinnati successfully argued that this court’s decision in Advance Watch 3 precluded the *551 misappropriation of advertising ideas or style-of-doing-business claim. The district court determined that Cincinnati’s policy did not cover the infringement of trade dress and trademark claims because the heart of ASP’s allegation — that Zen marketed and advertised a similar product which infringed on ASP’s trademarks and trade dress — was not an “advertising injury” because it did not arise predominantly from advertising activities. However, the district court determined that it could not conclude that ASP’s allegations were not covered under the infringement-of-slogan portion of Cincinnati’s policy. Following general principles of Michigan law, the court reasoned that any doubts as to the policy’s coverage are to be resolved in favor of the insured.
The district court granted Cincinnati’s motion for summary judgment in part and denied it in part. First, the court determined that the underlying lawsuit was covered under the “advertising injury” provision because the “advertising” and “causation” requirements were met. However, only the potential “infringement of slogan” claim generated a duty to defend because Advance Watch precluded a defense under the “misappropriation of advertising ideas or style of doing business” and the “disparagement” claims. Second, the district court granted Zen’s partial summary judgment motion: because one of ASP’s possible claims against Zen was based on infringement of slogan and because Zen’s policy with Cincinnati covered infringement of slogan actions, Cincinnati had a duty to defend. The district court reasoned that under the insurance policy, Cincinnati was obligated to defend Zen against claims for “advertising injuries of infringement of slogan.” J.A. at 116 (Dist.Ct.Op.). The court concluded that because Cincinnati was obligated to defend Zen on this one potential claim, Cincinnati was responsible for the attorney fees and costs in defending the entire underlying action. In its judgment, the district court ordered that Cincinnati had a duty to indemnify Zen in the underlying infringement of slogan action and a duty to defend Zen on all of ASP’s claims against Zen in the underlying action. Cincinnati now appeals from this judgment with respect to the duty-to-defend component.
III. ANALYSIS
A. Standard of Review
Cincinnati argues on appeal that the district court erroneously granted partial summary judgment to Zen when it determined that Cincinnati had a duty to defend Zen in the ASP action. We review de novo a district court’s grant of summary judgment.
Rannals v. Diamond Jo Casino,
B. Duty to Defend
1. Michigan Insurance Contracts
The parties do not dispute that Michigan law governs. Under Michigan law, courts construe an insurer’s duty to defend more broadly than its duty to indemnify.
See generally Radenbaugh v. Farm Bureau Gen. Ins. Co. of Mich.,
In liability policies, the obligation of the insurer depends upon the allegations of the underlying complaint. The insurer only has a duty to defend the insured if the charges against the insured in the underlying action arguably fall within the language of the policy. However, the terminology that was used by the underlying plaintiff in the complaint is not dispositive. Instead, the analysis of the issue must include the actual cause of the injury. Any doubt as to the insurer’s liability must be resolved in favor of the insured. Moreover, where only some of the claims against the insured party are covered, the insurer must defend the whole claim until it becomes apparent that no recovery is possible under the covered theory.
Advance Watch,
In general, interpretation of insurance policies is governed by the same principles used to interpret ordinary contracts.
Nikkei,
2. Slogan Infringement
The broad question we must address is whether the ASP complaint “arguably” stated any claim for liability for an advertising injury, as defined in Cincinnati’s insurance policy.
Freeman,
According to Cincinnati’s policy, “advertising injury” coverage has three requirements. First, there must be an advertising activity by the insured. Second, the underlying action must implicate a specific “advertising injury” covered by the policy. Third, there must be a causal relationship between the alleged advertising injury and the insured’s advertising activity.
See GAF Sales & Serv., Inc. v. Hastings Mut. Ins. Co.,
224 MichApp. 259,
Cincinnati’s initial argument on appeal is that the district court’s conclusion that “The Wearable Light” was a slogan was erroneous. In support, Cincinnati comments that the district court noted that ASP’s complaint never referred to “The Wearable Light” as a slogan, but rather claimed that it was a valuable trademark in and of itself. Moreover, ASP’s complaint states that it uses this phrase to market and sell its “SAPPHIRE” lights and never states that “it promotes the sale of those lights by creating a separate impression from the actual name of product itself.” Appellant’s Br. at 15. In Cincinnati’s estimation, “The Wearable Light” appears to be nothing more than an alternative name for LED lights. Cincinnati relies heavily on a Second Circuit case,
Hugo Boss Fashions, Inc. v. Federal Insurance Co.,
In opposition, Zen points out, first, that the fact that ASP’s complaint never called “The Wearable Light” a slogan 8 does not immunize Cincinnati from a duty to defend. Second, the definition lifted from Hugo Boss and cited by Cincinnati was limited to trademarked slogans, whereas in Cincinnati’s policy the coverage extends to “infringement ... of slogan,” without any requirement that it be trademarked. J.A. *555 at 64 (Compl., Attach.2). Zen argues, therefore, that the only relevant issues in the determination of slogan infringement are: (1) whether ASP alleged in its complaint that it owned the slogan, and (2) whether ASP alleged that Zen’s use of the slogan infringed on ASP’s rights. Third, Zen argues that even if the Hugo Boss definition for trademarked slogans is applicable, the phrase “The Wearable Light” meets its requirements.
We agree with the district court’s analysis and determine that summary judgment for Zen is appropriate with respect to Cincinnati’s duty to defend on ASP’s potential slogan infringement claim. The Michigan Court of Appeals has stated that “[a]n insurer has a duty to defend, despite theories of
liability
asserted against any insured which are not covered under the policy, if there are any theories of
recovery
that fall within the policy.”
Radenbaugh,
In the present case, ASP’s complaint states that “[Zen’s] use of advertisements and packaging utilizing and bearing ASP’s WEARABLE LIGHT trademark in connection with the sale of handheld LED flashlights without ASP’s authorization or consent, has been with full knowledge of the industry’s association of the WEARABLE LIGHT mark with ASP ... [and] was commenced with and for the purpose of willfully trading on the reputation of ASP and its flashlights.” J.A. at 140 (ASP Compl. ¶54). In addition, the complaint asserts that Zen “appropriat[ed] ... ASP’s WEARABLE LIGHT trademark,” and that the “marketing and selling handheld LED flashlights” using ASP’s “WEARABLE LIGHT” trademark has resulted in “adverse economic impact on the business and reputation of ASP.” 9 J.A. at 137, 140 (ASP Compl. ¶¶ 36, 54). Freed from the precise language of the allegations, we look to the underlying complaint’s basis for recovery.
*556
In determining whether Zen’s alleged use of the phrase “The Wearable Light” states a claim for slogan infringement within the definition of the policy, we turn first to the policy itself.
See Term. Valley Auth. v. Exxon Nuclear Co.,
Next, we must determine whether the phrase “The Wearable Light”, as used in ASP’s advertisements, potentially constitutes a slogan such that Zen’s alleged infringement invokes Cincinnati’s duty to defend. The Joint Appendix contains an ASP advertisement for its LED flashlight that allows us to consider this question for ourselves.
11
In this ASP advertisement, “SAPPHIRE” followed by the registered trademark emblem is in large bold print above the picture of the LED flashlight. Directly beneath “SAPPHIRE,” the phrase “The Wearable Light” appears smaller and notably is not followed by the registered trademark emblem. From this advertisement, “SAPPHIRE” appears to be the name of the product, while “The Wearable Light” can easily be construed as a “catchword or catch phrase” used by the manufacturer to promote its product.
See Random House Unabridged Dictionary
1800 (2d ed.1993). Relying on other common definitions of slogan, “The Weara
*557
ble Light,” as used in the ASP advertisement also can be considered “[a] brief attention-getting phrase used in advertising or promotion.”
Palmer v. Truck Ins. Exch,
ASP’s assertions of ownership over the phrase “The Wearable Light” together with Zen’s alleged use of the same phrase in connection with its LED flashlights are arguably allegations of slogan infringement.
See Advance Watch,
IV. CONCLUSION
Based on the foregoing analysis, we AFFIRM the district court’s decision to deny Cincinnati’s summary judgment motion in part and to grant Zen’s partial summary judgment motion declaring that Cincinnati has a duty to defend on the infringement of slogan claim and thereby has a duty to defend the whole ASP case.
Notes
. Both Zen and Cincinnati refer to the allegedly infringing phrase as "WEARABLE LIGHT.” We suspect that they chose to refer to the phrase without the article "The” and using all capital letters because ASP's complaint referred to the phrase as "WEARABLE LIGHT.” Because Cincinnati's obligation to defend is determined by the allegations in ASP's complaint regarding infringement of ASP's phrase, we are concerned with how the phrase was used by ASP in its advertisements. Thus, we will mimic ASP's advertisements when we refer to the phrase as "The Wearable Light” throughout this opinion. However, when we are quoting directly from the complaint or other filings in this case, we will quote the phrase as it appeared in the quoted material.
. Because the district court granted Cincinnati's motion for summary judgment on indemnification as to the disparagement and misappropriation claims and Zen never cross-appealed from that decision, the issue of indemnification on the disparagement and misappropriation claims is not before this court. In addition, Cincinnati does not make the fallback argument on appeal that, should this court find that Cincinnati has a duty to defend the slogan claim, Cincinnati nonetheless has no duty to indemnify with respect to that claim. Although the district court's decision on indemnification for the slogan infringement claim may have been a bit premature, we will not address this matter because Cincinnati chose not to raise this issue in its briefs.
See Buziashvili v. Inman,
. The district court described the similarity of the issues in Advance Watch to the issues presented in this case:
In Advance Watch, an insured pen manufacturer sought defense and indemnification from its general liability insurer, Travelers, from an underlying action for trademark infringement, unfair competition, and dilution. The insured's policy with Travelers was nearly identical to the Policy in this case, providing for defense and indemnification for advertising injury for the same enumerated "advertising injuries” [alleged here].... The district court, after reviewing Michigan law concerning a liability insurer’s duty to defend, as well as Michigan law on the interpretation of insurance policies, agreed with the insured's argument that "misappropriation of style of doing business” was "broad enough to embrace claims that the insured copied a design explicitly protected by trademark.” The district court therefore awarded summary judgment in favor of the insured.
.... In rejecting the district court's broad interpretation of the term "misappropria *551 tion of style of doing business,” the [Sixth Circuit] noted that there existed a body of case law defining this term as a separate category of actionable conduct; therefore the term in Travelers' policy did not refer to a category or grouping of actionable conduct which includes trademark or trade dress infringement. In addition, the Court found significant that the policy definition of "advertising injury” did not include any express reference to trademark infringement. Because of the common recognition of trademark and trade dress infringement as distinct categories of actionable conduct, the Court found that if Travelers had intended to provide coverage for liability under these claims it would have referred to them by name in the policy, as it did with “infringement of copyright, title or slogan."
J.A. at 104-05 (Dist.Ct.Op.) (citations and footnote omitted).
. The district court identified the following problems with considering "The Wearable Light" a slogan:
ASP never refers to WEARABLE LIGHT as a slogan; rather, it alleges that it owns a valuable trademark for this name and that it has an application for its registration pending.... WEARABLE LIGHT seems to be more a descriptive, than a promotional, phrase. Further, it appears to be far less promotional than the examples cited by the court in Hugo Boss [Fashions, Inc. v. Fed. Ins. Co.,252 F.3d 608 (2d Cir.2001)]: "Just Do It" as a slogan used to promote the house mark Nike and "Don't Leave Home Without Us” as a slogan to promote the *554 house mark "American Express.” ... And, perhaps most importantly, ASP’s complaint does not allege that it has developed good name and good will in the WEARABLE LIGHT mark to promote the SAPPHIRE mark; rather, it alleges that the WEARABLE LIGHT mark is used to directly market and sell the LED flashlights.
J.A. at 112-13 (Dist.Ct.Op.).
. A "house mark” is a company name or its product line.
Hugo Boss,
. A "product mark” specifically references a particular product. Id,
. Without citing any authority, Cincinnati argues that slogans cannot be protected from infringement unless they are subject to trademark registration and protection. In Cincinnati's opinion, "The Wearable Light" cannot be subject to trademark registration and protection because (1) it fails to distinguish ASP’s LED lights from any other similarly manufactured light; (2) the phrase is merely descriptive and has little or no promotional effect (as the district court noted); and (3) the phrase "The Wearable Light” has no demonstrated secondary meaning.
It is clear that not all slogans are trademarks.
See MicroStrategy Inc. v. Motorola, Inc.,
.Instead, ASP alleged that it had a valuable trademark in the name "The Wearable Light” and that its trademark registration application was pending.
. Additional assertions in the ASP complaint lend support to the existence of a slogan infringement claim:
ASP advertises, markets and sells handheld LED flashlights throughout the United States using the trademarks SAPPHIRE and WEARABLE LIGHT.... ASP has invested a considerable amount of time, money, and effort in promoting its flashlights throughout the United States, including its promotion of the SAPPHIRE and WEARABLE LIGHT trademarks and the distinctive look of its handheld LED flashlight.... ASP’s extensive and exclusive use of its SAPPHIRE and WEARABLE LIGHT trademarks on its goods, and in advertising thereof, has resulted in such trademarks and the distinctive look of the flashlights themselves becoming widely recognized by the public as identifying the goods of ASP and distinguishing ASP's goods from all other goods. Consequently, ASP has built up and achieved extensive good will in conjunction with the sale of said goods under its SAPPHIRE, WEARABLE LIGHT and product configuration trademarks.
J.A. at 133-34 (ASP Compl. ¶¶ 11, 16, 17).
. Other definitions for slogan include: (1) "A brief attention-getting phrase used in advertising or promotion,”
Palmer v. Truck Ins. Exch.,
. Cincinnati points out that the district court used Zen's advertisements when it sought to determine whether the phrase "The Wearable Light” was a slogan, and that those advertisements are "totally irrelevant” to ASP’s claim that it is a slogan. Appellant’s Br. at 17-19. However, the parties appear to dispute whether the district court relied on the incorrect advertisements. Compare Appellant's Br. at 17-18 ("The District Court undeniably relied on the wrong advertisements for its opinion .... Furthermore, it failed completely to discuss any advertisement or other material attributable to ASP.”), with Appellees' Br. at 28 (noting that the ASP complaint contained this advertisement). Appellees indicate that sample advertisements from both ASP and Zen were attached to ASP's complaint. Ap-pellees' Br. at 29. It is unclear from the district court opinion and the joint appendix what are the precise advertisements relied on by the district court.
. A duty to defend on one claim creates a duty to defend as to all claims. Advance Watch, 99 F.3d at 799. Therefore, we do not need to consider whether ASP’s other claims would independently trigger a duty to defend.
