Green Machine Corporation appeals the entry of summary judgment against it on the issue of Zurich-American Insurance Group's duty to defend and indemnify it in an underlying patent infringement action. For the following reasons, we affirm.

In 1995, Chiuminatta Concrete Concepts, Inc. and its principals ("Chiuminatta") filed suit in a California federal district court against Green Machine Corporation ("Green Machine") and others. Among other things, Chiuminatta alleged that Green Machine's manufacture, sale and promotion of certain concrete-cutting saws infringed and induced others to infringe Chiuminatta's products and methods patents. In November of 1996, the California district court entered judgment for Chiuminatta, and Green Machine appealed.

In July of 1997, Green Machine sought insurance coverage for Chiuminatta's patent infringement claims under a policy of general liability insurance issued to Green Machine by Zurich-American Insurance Group ("Zurich"). Green Machine maintained that Chiuminatta's claims fell within the "advertising injury" coverage provided by Zurich's policy. Zurich denied Green Machine's request for coverage in June of 1998.

Shortly thereafter, the Court of Appeals for the Federal Circuit reversed the district court's judgment as to the product patent, holding that Green Machine's manufacture, sale, and use of its concrete-cutting saw did not infringe the product patents of Chiuminatta. See Chiuminatta Concrete Concepts, Inc. v. Cardinal Industries, Inc., 145 F.3d 1303 (Fed.Cir.1998). The Federal Circuit, however, affirmed the district court's judgment that Green Machine's sales demonstrations encouraged cutting concrete using a method patented by Chiuminatta, thereby both violating and inducing others to violate Chiuminatta's methods patent. Id.1

In May of 1999, Green Machine filed a three count complaint in state court seeking a declaration that Zurich was required to defend and indemnify it in the underlying Chiuminatta patent action. Zurich removed the action to the United Stated District Court for the Eastern District of Pennsylvania, where the parties filed cross-motions for summary judgment.

In August of 2001, the Pennsylvania district court granted Zurich's motion for summary judgment and denied Green Machine's cross-motion. The court held that Chiuminatta's complaint did not allege an "advertising injury" and, consequently, Zurich had no duty to defend Green Machine in the lawsuit. We review this conclusion of law de novo. Township of Center, Butler County, Pennsylvania v. First Mercury Syndicate, Inc., 117 F.3d 115, 117 (3d Cir.1997). The district court had diversity jurisdiction of this case pursuant to 28 U.S.C. § 1332, and we have appellate jurisdiction under 28 U.S.C. § 1291.

Zurich's duty to defend and indemnify Green Machine is contained in Section I(B) of the policy which provides the following:

We will pay those sums that the insured becomes legally obligated to pay as damages because of "personal injury" or "advertising injury" to which this insurance applies.

Zurich denied coverage to Green Machine based upon its position that the allegations in the underlying lawsuit do not state a claim for advertising injury. Under the policy, an advertising injury, among other things, is one arising out of the "misappropriation of advertising ideas or style of doing business."2 Green Machine contends that Chiuminatta's claims can appropriately be viewed as both of these types of advertising injury.

We have recently held that "to be covered by the policy, allegations of ... misappropriation have to involve an advertising idea, not just a nonadvertising idea that is made the subject of advertising." Frog, Switch & Mfg. Co. v. Travelers Ins. Co., 193 F.3d 742, 748 (3d Cir.1999). Misappropriating advertising ideas is the wrongful taking of an idea about the solicitation of business and customers. Id.3

In this case, there are no such allegations.4 Chiuminatta's complaint alleges that Green Machine infringed its concrete-cutting patents by creating similar products or copying certain patented methods. There is no allegation that Green Machine took any of Chiuminatta's marketing, promotional, or advertising materials or ideas. The only connection between Chiuminatta's claim and advertising is that Chiuminatta also alleges that, after Green Machine "stole" its patented method of cutting concrete, it advertised that method to others, thereby inducing them to infringe the patent as well.

Advertising injury is not, however, the same thing as advertising per se. Advertising injury is the misappropriation of another's advertising idea or concept. Green Machine argues that "Chiuminatta's advertising concept [was] to solicit its relevant market to cut concrete using its patented method" (emphasis added). Thus, Chiuminatta's advertising idea which Green Machine contends it was accused of misappropriating was to advertise. Under this theory, any competitor of Chiuminatta's who advertises — no matter what the content of that advertising — has misappropriated Chiuminatta's advertising idea to advertise. This is not what we mean by advertising injury since, were that the meaning, there could be no advertising without injury. Allegations that Green Machine stole a patented method for cutting concrete and also advertised the results of that theft, does not convert the underlying theft into "advertising injury." Id. at 744.

B. Misappropriation of Style of Doing Business

Green Machine also asserts that Chiuminatta's complaint can be fairly read to allege advertising injury by way of misappropriation of "style of doing business." Style of doing business has routinely been characterized as referring to a company's "comprehensive manner of operating its business." Hyman v. Nationwide Mut. Fire Ins. Co., 304 F.3d 1179, 1188 (11th Cir.2002) (citing Novell, Inc. v. Federal Ins. Co., 141 F.3d 983, 986 (10th Cir.1998) (collecting cases)). Green Machine contends that Chiuminatta's patented method for cutting concrete is its "manner of operating its business" and, therefore, its style of doing business.5

We have already rejected this overly broad view. In Frog, Switch, we explained that "style of doing business" is "a plan for interacting with consumers and getting their business." Id. at 749-50. Style of doing business, therefore, refers to a company's marketing approach, not its production or product. Chiuminatta's method of cutting concrete is like a "product."6 It is not a marketing strategy or a "plan for interacting with consumers and getting their business."7 Chiuminatta alleges not that Green Machine copied its marketing strategy or style of attracting customers, but that Green Machine copied its patented method for cutting concrete in order to sell its own saws, thereby inducing others to infringe on the patented method as well. These allegations do not state a claim for misappropriation of Chiuminatta's marketing style used to sell its concrete-cutting method, but rather for theft of the underlying method itself.

Misappropriation of an advertising idea is the wrongful taking of an idea concerning the solicitation of business and customers. Misappropriation of a style of doing business is the wrongful taking of a company's plan for interacting with consumers and getting their business. There are no such allegations in the underlying action which forms the basis for Green Machine's request for coverage under its policy of insurance with Zurich American. Accordingly, the judgment of the District Court denying coverage will be affirmed.
