ADKINS, J.
Under Maryland law, an insurance company has a duty to defend its insured for any claims brought against it that are potentially covered under the insured’s policy. Thus, a duty to defend may extend even beyond instances in which an insured is liable and the insurer must indemnify. In this case, we must assess whether an insurance company had a duty to defend its insured under a commercial general liability policy’s “advertising injury” clause against a suit sounding in breach of contract and arising out of a joint business venture.
FACTS AND LEGAL PROCEEDINGS1
The Business Venture
In October 2006, Robert M. Gray, President of RMG Direct, Inc. (“RMG”), first met John F. Black, President and Chief Executive Officer of Blackstone International, Ltd. (“Blackstone”). During their initial conversation, Black informed Gray that he “was in the business of manufacturing and selling lamps and other lighting products designed to assist low vision consumers.” Gray then informed Black of his role at RMG and his “professional background in the vision field.” The two men then proposed a joint venture to “market and sell lighting [689]*689products to people with low vision problems,” and agreed to discuss the venture at a later date.
Approximately one month later, Gray and Black met to discuss the possibility of working together. At this time, Gray outlined his experience in low vision medicine and his working relationships with many of the field’s leading practitioners. In early December 2006, Gray visited Blackstone’s offices, where he met Blackstone’s Product Development Manager and a member of its sales department. At this meeting, Black and Gray “agreed that RMG and Blackstone would form a confidential relationship and collaborate [on a] joint venture to develop plans for the design, marketing and sale of low vision lighting products to retailers[.]” Gray also agreed to work “in exchange for remuneration.”
Throughout the next four years, Gray — working on behalf of RMG — worked in collaboration with Black and Blackstone employees to develop and market their joint venture. During this time, Gray performed multiple tasks without compensation, including: (1) developing the product brand name “Vision Enhance”; (2) creating graphics for use in sales sheets; (3) developing and reviewing packaging and marketing of “Vision Enhance”; (4) contacting low vision experts and sufferers on behalf of the venture, which involved obtaining written testimonials; and (5) “procur[ing] the placement of a full page color advertisement in an industry journal,] introducing the ‘Vision Enhance’ brand.”
As part of his work with Blackstone, Gray participated in the development of a sales presentation to Wal-Mart Stores, Inc. (“Wal-Mart”) in an effort to place the product line for sale in its stores. Although Gray did not attend the presentation, he played a significant role in creating the materials and responding to Wal-Mart’s inquiries. Although Black had informed Gray that no progress had been made with WalMart, Gray learned that “Vision Enhance” was stocked and sold in Wal-Mart locations across the United States. Blackstone continued to sell “Vision Enhance” and other low vision lighting products — which Gray believes were procured [690]*690through its initial relationship with the retailer via “Vision Enhance” — under the label “Mainstays” at Wal-Mart locations. Blackstone “us[ed] all, or substantially all, of the ideas, information, input and efforts of Gray[,]” including “the use of the ‘Vision Enhance’ name on the boxes[, and use of] the same or substantially similar box design, copy on the box, and product instructions[.]”
While performing this work for Blackstone, Gray believed that RMG and Blackstone had reached an agreement that Blackstone would create a new division for its low vision products, and that RMG would receive a 7% sales commission for and a 50% equity interest in the low vision products. In mid-2007, Gray approached Black in an effort to memorialize their verbal agreement. Over the course of the following months, Gray proposed multiple written agreements, each of which Black modified or rejected. The two men never reached a written agreement.
On February 22, 2010, RMG filed suit against Blackstone and Black in the Circuit Court for Baltimore County. It later filed two amended complaints, alleging substantially the same facts and the following causes of action: breach of contract (Count I); promissory estoppel (Count II); unjust enrichment (Count III); quantum meruit (Count IV); intentional misrepresentation (Count V); and accounting (Count VI). This Second Amended Complaint formed the basis of the underlying suit.
Blackstone’s Insurance Policy
Blackstone has been insured by Maryland Casualty Company and Northern Insurance Company of New York (collectively, “Insurers”) for commercial general liability insurance since 2001. Its Commercial General Liability Coverage Form (the “Policy”) included coverage for Personal and Advertising Injury Liability. In relevant part, the Policy provides:
[Insurer] will pay those sums that the insured becomes legally obligated to pay as damages because of “personal and advertising injury” to which this insurance applies. We will have the right and duty to defend the insured against [691]*691any “suit”[2] seeking those damages. However, we will have no duty to defend the insured against any “suit” seeking damages for “personal and advertising injury” to which this insurance does not apply. We may, at our discretion, investigate any offense and settle any claim or “suit” that may result.3
In part, the Policy defines “personal and advertising injury” as “injury ... arising out of ... [t]he use of another’s advertising idea in your ‘advertisement.’ ”4 Under the terms of the Policy, “ ‘Advertisement’ means a notice that is broadcast or published to the general public or specific market segments about [692]*692your goods, products or services for the purpose of attracting customers or supporters.”5
On February 17, 2011, Blackstone and Black wrote to Insurers, requesting coverage and litigation defense under the personal and advertising injury provisions of the Policy.6 On May 17, 2011, Insurers filed a Complaint for Declaratory Judgment, seeking a judgment that they had no duty to defend the claims because, they argued, the Second Amended Complaint did not allege that Blackstone had engaged in advertising, that RMG had suffered an advertising injury, or that there was any “causal connection between any of RMG’s claimed damages ... and any advertising conducted by Blackstone.” Insurers also contended that all six counts in the Second Amended Complaint were excluded from coverage by the Policy’s terms. Thus, Insurers asserted, there was no potentiality of coverage for Blackstone’s claim, and Insurers had no duty to defend.
Summary Judgment Proceedings
The parties filed cross motions for summary judgment. Following a hearing, the Circuit Court entered summary judgment in favor of Insurers. Blackstone appealed to the Court of Special Appeals, which reversed the Circuit Court. Blackstone Int’l Ltd. v. Md. Cas. Co., 216 Md.App. 471, 477, 88 A.8d 792, 795 (2014).
[693]*693The intermediate appellate court concluded that the Policy’s definition of “advertisement” was implicated in a Blackstone website that allegedly used RMG’s advertising ideas, that “Vision Enhancement” product packaging constituted an advertisement, and that Gray’s advertising ideas could be described as “another’s,” although RMG contended that Blackstone owned the rights to the ideas due to their agreement. Id. at 482-85, 88 A.3d at 798-800. The Court of Special Appeals also rejected Insurers’ contention that RMG did not allege an advertising injury. Id. at 486, 88 A.3d at 801. Concluding that Insurers had waived any defense raised by the Policy’s exclusions, it reasoned that their duty to defend depended only upon whether RMG’s claims “ ‘arose out of the use of RMG’s advertising ideas in Blackstone’s advertisements, without regard to whether the acts were intentional or rooted in breach of contract.” Id. at 488-89, 88 A.3d at 802-03. The court also relied upon the exclusions as support for its conclusion that “had intentional conduct and breaches of contract not been excluded, they would fall within the agreement’s broad and unambiguous definition of ‘advertising injury.’ ” Id. at 488, 88 A.3d at 802 (emphasis in original). The Court of Special Appeals concluded that RMG’s unjust enrichment claim did arise out of Blackstone’s use of its advertising idea, and, thus, that Maryland law obligated Insurers to defend Blackstone against all of RMG’s claims. Id. at 489-90, 88 A.3d at 803-04.
We granted Insurers’ Amended Petition for Writ of Certiorari to consider the following questions:
1. Did the [Court of Special Appeals] err in holding that product packaging was “advertisement,” and that the “use of another’s advertising idea” need not be “wrongful use,” when it substituted its own definitions of those terms for the clear and unambiguous definitions contained in the Policy?
2. Did the [Court of Special Appeals] err in applying this Court’s binding precedent requiring an insured to establish all three elements of coverage for “advertising injury” to trigger the duty to defend by concluding that [694]*694the “causal relationship” element was not necessary in this case?
3. Did the [Court of Special Appeals] err in finding that Insurers waived policy exclusions as bases for denial of coverage and creating liability beyond the bounds of the Policy when, as a matter of public policy, coverage may not be expanded by waiver?
4. Did the [Court of Special Appeals] err in finding that Insurers waived Policy exclusions as bases for denial of coverage when policy exclusion defenses were raised, argued, and preserved at the trial court level and on appeal?
Because we answer yes to the second question, we need not address the other questions and shall reverse the judgment of the Court of Special of Appeals.
STANDARD OP REVIEW
We review a grant of summary judgment as a matter of law. Eng’g Mgmt. Servs. v. Md. State Highway Admin., 375 Md. 211, 229, 825 A.2d 966, 976 (2003). “The standard for appellate review of a trial court’s grant or denial of a summary judgment motion is whether the trial court was legally correct.” Sheets v. Brethren Mut. Ins. Co., 342 Md. 634, 638, 679 A.2d 540, 542 (1996) (citation omitted). Thus, we conduct an independent review of the record to determine whether a genuine dispute of material fact exists and whether the moving party is entitled to judgment as a matter of law. Walk v. Hartford Cas. Ins. Co., 382 Md. 1, 14, 852 A.2d 98, 105-06 (2004). “We review the record in the light most favorable to the non-moving party and construe any reasonable inferences which may be drawn from the facts against the movant.” Id. at 14, 852 A.2d at 106 (citation omitted).
We construe an insurance policy according to contract principles. Moscarillo v. Prof'l Risk Mgmt. Servs., Inc., 398 Md. 529, 540, 921 A.2d 245, 251 (2007). Maryland follows the objective law of contract interpretation. Sy-Lene of Wash., Inc. v. Starwood Urban Retail II, LLC, 376 Md. 157, [695]*695166, 829 A.2d 540, 546 (2003). Thus, “ ‘the written language embodying the terms of an agreement will govern the rights and liabilities of the parties, irrespective of the intent of the parties at the time they entered into the contract.’ ” Long v. State, 371 Md. 72, 84, 807 A.2d 1, 8 (2002) (quoting Slice v. Carozza Props., Inc., 215 Md. 357, 368, 137 A.2d 687, 693 (1958)). “When the clear language of a contract is unambiguous, the court will give effect to its plain, ordinary, and usual meaning, taking into account the context in which it is used.” Sy-Lene, 376 Md. at 167, 829 A.2d at 546 (citation omitted). “Unless there is an indication that the parties intended to use words in the policy in a technical sense, they must be accorded their customary, ordinary, and accepted meaning.” Lloyd E. Mitchell, Inc. v. Md. Cas. Co., 324 Md. 44, 56-57, 595 A.2d 469, 475 (1991) (citations omitted). Although Maryland does not follow the rule that insurance contracts should be construed against the insurer as a matter of course, any ambiguity will be “ ‘construed liberally in favor of the insured and against the insurer as drafter of the instrument.’ ” Dutta v. State Farm Ins. Co., 363 Md. 540, 556-57, 769 A.2d 948, 957 (2001) (emphasis in original) (citation omitted).
DISCUSSION
Insurer’s Duty To Defend And Potentiality Of Coverage
In Brohawn v. Transamerica Insurance Company, 276 Md. 396, 347 A.2d 842 (1975), we recognized an insurance company’s duty to defend its insured for all claims which are potentially covered under an insurance policy. We explained:
The obligation of an insurer to defend its insured under a contract provision ... is determined by the allegations in the tort actions. If the plaintiffs in the tort suits allege a claim covered by the policy, the insurer has a duty to defend. Even if a tort plaintiff does not allege facts which clearly bring the claim within or without the policy coverage, the insurer still must defend if there is a potentiality that the claim could be covered by the policy.
[696]*696Id. at 407-08, 347 A.2d at 850 (emphasis added) (citations omitted). To ascertain whether an insurer has a duty to defend its insured, we engage in a two-part inquiry:
In determining whether a liability insurer has a duty to provide its insured with a defense in a tort suit, two types of questions ordinarily must be answered: (1) what is the coverage and what are the defenses under the terms and requirements of the insurance policy? (2) do the allegations in the tort action potentially bring the tort claim within the policy’s coverage? The first question focuses upon the language and requirements of the policy, and the second question focuses upon the allegations of the tort suit.
St. Paul Fire & Marine Ins. Co. v. Pryseski, 292 Md. 187, 193, 438 A.2d 282, 285 (1981). “[W]here a potentiality of coverage is uncertain from the allegations of a complaint, any doubt must be resolved in favor of the insured.” Aetna Cas. & Sur. Co. v. Cochran, 337 Md. 98, 107, 651 A.2d 859, 863-64 (1995).
Bearing these principles in mind, we consider the allegations in RMG’s Second Amended Complaint to determine whether the action potentially brings a claim within the Policy’s coverage. In determining whether Insurers had a duty to defend, we are restricted in the first instance to the Second Amended Complaint and may not look to extrinsic evidence. See Walk, 382 Md. at 16, 852 A.2d at 106 (“An insured may rely on extrinsic evidence where the underlying complaint neither conclusively establishes nor negates a potentiality of coverage.” (citation and internal quotation marks omitted)).7 As will be evident infra, because we find the terms of Blackstone’s Policy and the allegations in RMG’s Second Amended [697]*697Complaint to be conclusive, we do not consider any extrinsic evidence.
Advertising’ Injury In Commercial General Liability Policies
Blackstone contends it is entitled to insurance coverage under the advertising injury provision of its commercial general liability insurance policy. As discussed supra, the Policy8 covers advertising injury, which it defines, in part, as “injury ... arising out of ... [t]he use of another’s advertising idea in [Blackstone’s] ‘advertisement.’ ” It further defines “advertisement” as “a notice that is broadcast or published to the general public or specific market segments about [Blackstone’s] goods, products or services for the purpose of attracting customers or supporters.” The Policy also contains an exclusion, which provides that advertising injury does not apply to that “[a]rising out of a breach of contract, except an implied contract to use another’s advertising idea in your advertisement[.]”
In the Second Amended Complaint, RMG asserted breach of contract, promissory estoppel, unjust enrichment, quantum meruit, intentional misrepresentation, and accounting for allegations including: (1) developing the product brand name “Vision Enhance”; (2) creating graphics for use in sales sheets; (3) developing and reviewing packaging and marketing of “Vision Enhance”; (4) contacting low vision experts and sufferers on behalf of the venture, including obtaining written testimonials; and (5) introducing the “Vision Enhance” brand [698]*698by placing a full-page color advertisement in an industry journal.9
Provisions offering coverage for advertising injury became common in commercial general liability policies during the second half of the Twentieth Century. 2 Jeffrey W. Stempel, Stempel on Insurance Contracts, § 14.06[A] 14-60-62 (3d. ed., 2015 supp.). Such provisions “provide[ ] coverage for damages that occur in the course of the insured’s advertising activities, arise out of one of the offenses enumerated in the policy, and occur during the policy period.” 2 Barry R. Ostrager & Thomas R. Newman, Handbook on Insurance Coverage Disputes, § 25.03, at 1970 (17th ed.). A court will consider three inquiries when determining whether a policy provides coverage for advertising injury: “(1) Is there an ‘advertising injury’ offense as defined by the policy?; (2) Was the offense committed in the course of advertising your goods, products or services?; and (3) Is there a causal connection between the advertising and the injury?”10 4 Leo P. Martinez, Marc S. Mayerson, & Douglas R. Richmond, New Appleman Insurance Law Practice Guide, § 43.15, at 43-23 (2015). These three elements have been recognized and applied in Maryland. [699]*699See Walk, 382 Md. at 16-17, 852 A.2d at 107 (“The [pjolicy requires that the underlying plaintiffs allege the potential for three things: (1) an ‘advertisement’; (2) an ‘advertising injury,’ ...; and (3) a causal relationship between the advertising injury and the alleged damages.”).
The Causal Connection Requirement
Insurers underscore the causal connection requirement. Citing Walk, they maintain that the Court of Special Appeals disregarded the requirement that there be a causal relationship between the advertising injury and the claimed damages and contend that RMG did not allege its damages were causally related to any Blackstone advertisement. For its part, Blackstone counters that the Court of Special Appeals considered the causal connection between advertisement and damages and properly concluded that it was subsumed in the Policy’s definition of “advertising injury.” It is helpful to preface our evaluation of these arguments with additional review of relevant authorities addressing advertising injury liability.
Advertising injury provisions are typically specified risk coverages whose terms “are designed to provide coverage for the enumerated claims only and not to provide generalized liability coverage.” Stempel at 14-62.6. Thus, “[t]o be covered, the claims made against the policy holder must arise from advertising activity. A highly attenuated connection to advertising is not sufficient to create coverage.” Id. at 14-62.7 (footnotes omitted).
To meet the causal connection requirement, “the advertising injury claimed must be ‘caused by an offense committed in the course of advertising.’ ” 3 New Appleman Law of Liability Insurance, § 17.02[2][c], at 17-15 (2d ed.2014). “When there are no allegations that the claimant suffered damages as a result of advertising, there will be no advertising injury claim.” New Appleman Insurance Law Practice Guide, § 43.18, at 43-29 (citation omitted). Although courts “have not discussed the causation issue in terms of proximate cause versus ‘but for’ causation ... there are overtones of this [700]*700distinction in the caselaw.” Id. Thus, “[t]he question is not whether the injury could have taken place without the advertising, but whether the advertising did in fact contribute materially to the injury.” Id.
Courts have addressed advertising injury’s causal connection requirement in a variety of different circumstances and have helped to define the parameters of coverage. At times, courts have found coverage. See, e.g., Am. Simmental Ass’n v. Coregis Ins. Co., 282 F.3d 582 (8th Cir.2002) (advertising injury clause implicated when insured cattle breeders association misdesignated cattle as “fullblood” in marketing and advertising materials, thereby reducing value of true “full-blood” cattle) (Montana law); R.C. Bigelow, Inc. v. Liberty Mut. Ins. Co., 287 F.3d 242 (2d Cir.2002) (advertising injury clause implicated when competitor’s underlying complaint alleged that insured had marketed herbal teas in new packaging with trade dress confusingly similar to that of competitor’s boxes) (Connecticut law); Letro Products, Inc. v. Liberty Mut. Ins. Co., 114 F.3d 1194 (9th Cir.1997) (advertising injury clause implicated when insured infringed upon competitor’s products when using photographs of competitor’s products in its promotional materials) (California law); Am. Safety & Risk Servs., Inc. v. Legion Indem. Co., 153 F.Supp.2d 869 (E.D.La.2001) (advertising injury clause implicated when insured falsely disseminated information that a competitor was no longer in business) (Louisiana law); Merchants Co. v. Am. Motorists Ins. Co., 794 F.Supp. 611 (S.D.Miss.1992) (advertising injury clause implicated when insured acquired and used competitor’s secret customer list to send direct mail solicitations to those customers) (Mississippi law); Air Eng’g, Inc. v. Indus. Air Power, LLC, 346 Wis.2d 9, 828 N.W.2d 565 (Wis.Ct.App.2013), review denied, 353 Wis.2d 430, 839 N.W.2d 617 (Wis.2013) (advertising injury clause implicated when company alleged that insured used its internet advertising system to place online ads for the purpose of attracting customers).
At other times the finding was no coverage. See, e.g., Walk, 382 Md. at 18, 852 A.2d at 108 (no advertising injury when complaint only alleged that insured “violated numerous agree[701]*701ments with his former employer not to solicit its clients or use its proprietary information”); Pac. Group v. First State Ins. Co., 70 F.3d 524 (9th Cir.1995) (no advertising injury when insured sabotaged a deal to purchase a third party’s hotel so that it could squeeze a partner out of the deal and acquire the hotel at a lower price because the injury arose from the squeeze-out and not any advertising) (California law); Info. Spectrum, Inc. v. The Hartford, 182 N.J. 34, 860 A.2d 926 (2004) (no advertising injury when insured misappropriated a computerized police reporting system because the alleged harm was not caused by the advertising act itself); Mylan Labs., Inc. v. Am. Motorists Ins. Co., 226 W.Va. 307, 700 S.E.2d 518 (2010) (no advertising injury when insured issued publication to drug providers of the price spread in the wholesale price of generic drugs). See generally Advertising Injury Insurance, 98 A.L.R.5th 1 (2002) (collecting cases). Despite our study of the cases presented by the parties and our extensive independent research, we have found no case that addressed a suit to collect a fee for creative services or enforce an alleged joint venture, like this suit.
Although expressed in six counts, the crux of RMG’s complaint is that Blackstone failed to accord RMG a share of profits or an equity interest in return for Gray’s services as called for in an oral contract between them. As might be discerned from the above cases, this claim differs markedly from those that have been recognized as falling within advertising injury coverage. In Bank of the West v. Superior Court,11 the “modern watershed case construing advertising injury coverage,”12 the California Supreme Court observed that the causal connection requirement limits commercial general liability policies so that they do not encompass every claim related to an insured’s business. This observation is instructive, and we agree with Insurers that the lack of causation is dispositive here.
[702]*702RMG plainly alleged that Gray and Black formed an oral contract — that they mutually promised to perform their ends of the bargain. One of the aims of the enterprise was for Blackstone to use Gray’s work in its advertisements. Given this agreement, it cannot be fairly said that RMG suffered injury from the use of advertising materials Gray willingly delivered to Blackstone for that purpose. The wrong RMG alleged was Blackstone’s failure to pay RMG a percentage of profits and give it an equity stake in the venture involving the sale of Blackstone’s product. The fallacy in Blackstone’s current claim against Insurers is that Blackstone’s use of RMG’s creative ideas could only enhance RMG’s claims for profits or an equity share, not injure him.
Novell, Inc. v. Federal Insurance Company, 141 F.3d 983 (10th Cir.1998) is another example of an injury caused by a breach of contract and not by an advertisement. In Novell, Inc. the underlying claim against Novell was based on claims by Ross, the designer of certain software, that Novell violated its oral and written representations to the plaintiff that Novell would not “use, appropriate, or usurp ideas or concepts [developed by Ross] or do anything to compete with Ross.” Id. at 985. The Tenth Circuit, applying Utah law, rejected Novell’s claim of an advertising injury, reasoning:
Here, Ross alleged Novell/WordPerfect, in direct violation of its own oral and written representations to Ross, misappropriated his product idea ... and developed and marketed a competing product.... Even if Novell/WordPerfect advertised or otherwise marketed [a competing product], the violations alleged by Ross were not the result of Novell/WordPerfect doing so. Rather, Ross was injured when Novel/WordPerfect created and sold a competing product in direct contravention of oral and written statements to him. The fact that it may have advertised the competing product to consumers simply did not cause Ross’ injuries.
Id. at 988 (omissions added); see also Microtec Research Inc. v. Nationwide Mut. Ins. Co., 40 F.3d 968, 971 (9th Cir.1994) (harm was “caused by misappropriation of the [computer] code, not by the advertising itself’).
[703]*703Courts have rejected other entreaties by insureds to extend comprehensive general liability coverage to breach of contract claims, because that would fundamentally alter the nature of the insurance relationship and effectively render the insurer a surety. See Fallon McElligott, Inc. v. Seaboard Sur. Co., 607 N.W.2d 801, 804 (Minn.Ct.App.2000) (“Insurer protection of contractual performance is provided by performance bonds, by errors-and-omissions policies, by insurer guarantees of indemnification agreements or debt repayment, and some other types of policies. But [the insured’s] enumerated-risks liability policy ... was not such a policy.”) (emphasis in original); Structural Bldg. Prods. Corp. v. Bus. Ins. Agency, 281 A.D.2d 617, 619, 722 N.Y.S.2d 559, 562 (N.Y.App.Div.2001) (“The general rule is that a commercial general liability insurance policy does not afford coverage for breach of contract, but rather for bodily injury and property damage. To hold otherwise would render an insurance carrier a surety for the performance of its insured’s work.” (citation omitted)). Although — unlike this case — the underlying suit against the insured in Fallon McElligott claimed professional negligence in addition to breach of contract, we still consider this case apropos.
Blackstone cannot expand the scope of its Policy simply by pointing to its “arising from” language. That language is intended to restrict, not expand, coverage. We find instructive the reasoning employed by the Minnesota Court of Appeals in Fallon McElligott, Inc. v. Seaboard Surety Company, supra. In that case, an advertising agency “prepared for a client advertisements that copyright holders believed violated their copyrights.” Fallon McElligott, 607 N.W.2d at 802. When its client sued for breach of contract and professional negligence, the advertising agency tendered the defense to its insurer, which denied coverage on the ground that it was beyond the scope of coverage. Id. The agency’s insurance policy provided that the insurer would defend any suit seeking damages “resulting from ... any infringement of copyright or of title or of slogan.”13 Id. at 803. The agency settled the [704]*704claim and attempted to recover settlement and defense costs from its insurer. Id. at 802.
The court rejected the agency’s arguments that the clause was implicated: “Because [the client’s] underlying claim is grounded on [the agency’s] failure to fulfill a contract obligation, it falls both outside the ... policy insuring clause and within the exclusion for ‘failure of performance of contract.’ ” Id. at 804. The court found unconvincing the insured’s argument that the policy’s “resulting from” language — similar to the “arising from” language found in Blackstone’s Policy— extended coverage to the claim:
[The insured] claims that the insuring clause (which covers “liability imposed upon” the advertising agency for “money damages resulting from * * * infringement of copyright”) covers the [underlying] claim, arguing that the losses [its client] sought to recover through its claim of contract breach and professional negligence should be viewed as “resulting from” the copyright violation. [The insured] tries to accomplish too much with the two words “resulting from.” The policy might well have used: “arising from,” “following upon,” “because of,” or a myriad of other phrases to describe a relationship of causation. But no matter what phrase was used, the intent would not have been to cover losses based on a “but-for-the-insured’s-conduct” standard.
Id. at 804-05. Similar to the sentiments articulated by other courts discussed supra, the Minnesota Court of Appeals expressed concern that a liberal interpretation of the term “resulting from” could drastically expand the scope of coverage beyond what was intended:
Insurance-industry scriveners would bear an unrealistic burden if an occasional phrase could convert a liability policy into a totally different type of policy. The policy in this case is — notwithstanding the “resulting from” phrase— [705]*705still an enumerated-perils policy providing protection against liability claims, rather than coverage for a failure to perform a contract.
Id. at 805.
We agree with the Minnesota court. Advertising injury clauses do not extend to breach of contract claims, and the mere inclusion of the phrase “arising from” in the Policy does not expand the scope to contract claims that happen to have a relationship with advertisement activity. To do so would transform insurers into sureties and subvert advertising injury coverage. Our view is consonant with the intermediate appellate court’s reasoning that contract-based claims do not meet the causal connection requirement because “the claims remained viable even if Blackstone had never used the disputed advertising ideas to sell its products.” Blackstone, 216 Md. App. at 489, 88 A.3d at 803. Thus, we agree with the holding of the Court of Special Appeals that insurance coverage was not invoked by counts I, II, V, and VI.
RMG’s Unjust Enrichment Count
We part company with the Court of Special Appeals, though, in its analysis of RMG’s unjust enrichment claim, which is the only count given credence by the intermediate court.14 In its decision to preserve Blackstone’s insurance defense, it reasoned:
RMG’s remaining unjust enrichment claim did, however, depend on Blackstone’s use of RMG’s advertising ideas. In that count, RMG alleged that Blackstone was unjustly enriched by retaining the benefit flowing from its use of RMG’s ideas in advertisements for Blackstone’s products. The complaint’s count for unjust enrichment therefore bore a “direct and substantial” relationship to the use of RMG’s advertising ideas in Blackstone’s advertisements, [706]*706making that claim an “advertising injury” under the parties’ insurance agreement.
Id. at 489-90, 88 A.3d at 803 (internal citation omitted) (emphasis added). We disagree because we see the same causation problem for the unjust enrichment count as we identified for the other counts.
Count III recites: “[RMG] conferred [a litany of] benefits upon Blackstone, with whom it had a confidential relationship.” This count includes the same nucleus of factual allegations as was discussed supra: RMG’s development of the brand name; creation of copy and graphics for sales sheets; development of packaging and marketing materials; and placement of a full page advertisement in an industry journal. The facts alleged merely reiterate those set forth in the Second Amended Complaint: Gray, on behalf of RMG, did creative work for Blackstone and did not receive the promised dividends.
We have described the core principle of unjust enrichment as follows:
A person who receives a benefit by reason of an infringement of another person’s interest, or of loss suffered by the other, owes restitution to him in the manner and amount necessary to prevent unjust enrichment.
Berry & Gould, P.A. v. Berry, 360 Md. 142, 151, 757 A.2d 108 (2000) (citation omitted). Unjust enrichment is a quasi-contract, a legal fiction we have described in earlier cases:
An express contract has been defined as an actual agreement of the parties, the terms of which are openly uttered or declared at the time of making it, being stated in distinct and explicit language, either orally or in writing. An implied contract is an agreement which legitimately can be inferred from intention of the parties as evidenced by the circumstances and the ordinary course of dealing and the common understanding of men. Finally, significant to our
[707]*707analysis is the definition of a quasi-contract.[15] Black’s Law Dictionary defines it as a
[l]egal fiction invented by common law courts to permit recovery by contractual remedy in cases where, in fact, there is no contract, but where circumstances are such that justice warrants a recovery as though there had been a promise. It is not based on intention or consent of the parties, but is founded on considerations of justice and equity, and on doctrine of unjust enrichment. It is not in fact a contract, but an obligation which the law creates in absence of any agreement, when and because the acts of the parties or others have placed in the possession of one person money, or its equivalent, under such circumstances that in equity and good conscience he ought not to retain it.

McDonald, 343 Ark. 507, 513, 36 S.W.3d 745, 749 (2001) (“[A]n implied-in-law contract is not even a contract at all, but an obligation imposed by law to do justice even though no promise was ever made or intended.” (emphasis added) (citing Calamari & Perillo, Contracts § 1-12 (3d ed.1987))).
Judge Moylan, writing for the Court of Special Appeals, also shed light on the nature of unjust enrichment:
When we enter the world of restitutionary remedies, we have arrived in the land of unjust enrichment. The restitutionary remedies and unjust enrichment are simply flip [708]*708sides of the same coin. The generative purpose of a restitutionary remedy is the prevention of unjust enrichment.
Alternatives Unlimited, Inc. v. New Balt. City Bd. of Sch. Comm’rs, 155 Md.App. 415, 454, 843 A.2d 252, 275 (2004) (“Alternatives ”).
The intermediate court in Alternatives looked to several treatises, including George E. Palmer, The Law of Restitution (1978), which described the relationship of unjust enrichment to the universe of other “sources of liability”:
It has been traditional to regard tort and contract as the two principal sources of liability at common law, although liability arising out of a fiduciary relationship has developed largely outside these two great categories. There is another category that must be separated from all of these; this is liability based in unjust enrichment.
Restitution based upon unjust enrichment cuts across many branches of the law, including contract, tort, and fiduciary relationship, but it also occupies much territory that is its sole preserve.
Id. at 452-53, 843 A.2d at 274 (emphasis added) (quoting The Law of Restitution, § 1.1, at 1-2).
The Alternatives court also consulted the venerable treatise, Dan B. Dobbs, Law of Remedies (2d Ed.1993) (“Dobbs”), which declared restitution to be a “ ‘simple word but a difficult subject, partly because restitutionary ideas appear in many guises.’ ” Alternatives, 155 Md.App. at 455, 843 A.2d at 275 (emphasis added) (quoting Dobbs at 551-52). The treatise described the evolution of unjust enrichment claims, and how they “ ‘went under a splendid variety of names like Money Had and Received, Money Paid, Money Lent, Quantum Meruit and many others,’ ” but “ ‘are now perceived to be merely subsets of restitution. The modern view is that unjust enrichment is a unifying principle for all such cases and restitution is the award made to ... those that used to be brought in equity.’ ” Id. at 454, 843 A.2d at 275 (emphasis and omission added) (quoting Dobbs at 564).
[709]*709This bit of history regarding unjust enrichment confirms our sense that unjust enrichment is both elemental and elusive. Nevertheless, we can see clearly that the unjust enrichment claim asserted against Blackstone does not qualify as a suit invoking the “Advertising Injury Liability” under the Policy. We explain.
The allegations and cause of action in Count III are duplicative of RMG’s Counts I and II — its breach of contract and promissory estoppel claims. As in those counts, the facts alleged clearly reveal that RMG was not injured by the advertisements Blackstone published. RMG was allegedly injured by Blackstone’s refusal to pay to RMG its share of the fruits of that advertising, i.e. profits. But the profits from the sale of Blackstone’s product were enhanced by the advertising which was the subject of RMG’s complaint.
Styling this count as “unjust enrichment” does not transform the nature of the injury. The measure of damages in an unjust enrichment claim is the value of the goods or services rendered by the plaintiff in the hands of the defendant. See Mogavero v. Silverstein, 142 Md.App. 259, 276, 790 A.2d 43, 53 (2002) (“Thus, the classic measurement of unjust enrichment damages is the gain to the defendant, not the loss by the plaintiff.” (citation and internal quotation marks omitted)). This is the same measurement of damages that would apply in RMG’s claims for breach of contract and promissory estoppel, which averred entitlement to a share of profits and an equity share in the joint venture, both of which were only enhanced by the advertising.
In sum, in all of the counts alleged by RMG, the advertising done by Blackstone using Gray’s ideas was all for the positive — it enhanced the value of the profits and joint venture interest to which RMG claimed entitlement. The advertising, even though utilizing Gray’s ideas, did not injure RMG. Unlike the majority of cases finding an advertising injury, it had no competing business. See, e.g., Letro Prods., Inc. v. Liberty Mut. Ins. Co., 114 F.3d 1194 (9th Cir.1997) (advertising injury clause implicated when insured infringed upon competitor’s [710]*710products when using photographs of competitor’s products in its promotional materials) and other cases cited, supra. Nor did it claim that it could profit from a different use of those advertising ideas, which were specifically designed for Blackstone’s product, “Vision Enhance.”
CONCLUSION
In conclusion, after reviewing the coverage and defenses under the Policy and the allegations in the underlying action, we hold that there was no potentiality of coverage. Blackstone did not show an advertising injury because none of the allegations of the underlying suit brought by RMG identified any injury that was caused by the advertisements created by RMG. Thus, Insurer had no duty to defend its insured. Accordingly, we reverse the judgment of the Court of Special Appeals.
