OPINION
Plaintiff-Appellee United National Insurance Co. is the commercial general liability insurer for defendant-appellant SST Fitness Corp. SST was sued by a third-party, Precise Exercise Equipment, Inc., for patent infringement, unfair competition and unjust enrichment. United National thereafter filed a motion for summary judgment, asserting that it had no duty to defend SST pursuant to the terms of the parties’ insurance policy. The district court granted summary judgment to United National, agreeing that United National had no duty to defend under the terms of the insurance policy. SST now appeals. For the reasons stated herein, we AFFIRM.
I.
Precise, a New Jersey corporation which markets and sells exercise equipment, invented and patented the “AB Trainer,” an abdominal exercise machine. SST, an Ohio corporation, advertises, markets, and sells exercise equipment, including the “Smart Crunch” line of abdominal exercisers. In 1996, Precise filed a complaint in the United States District Court for the Central District of California, alleging, inter alia, that SST “advertises, markets, and sells products” which infringe two of Precise’s patents, and that SST induced other companies into manufacturing, using, advertising and selling products which infringed these patents. Precise requested a declaration of willful infringement, an accounting of profits, injunctive relief and damages.
As a result of this litigation, SST tendered its defense to United National, which accepted the duty to defend, subject to a reservation of rights. United National thereafter filed a declaratory judgment action against SST, requesting a determination that it had no duty to defend, and a motion for summary judgment asserting *449 that, as a matter of law, it was entitled to such a finding. The district court referred the case to a magistrate judge, who heard oral argument, and thereafter recommended that United National’s motion for summary judgment be granted. The district court adopted the magistrate judge’s recommendation and granted United National’s motion for summary judgment. SST filed this timely appeal.

We review the district court’s order granting summary judgment
de novo. See Advance Watch Co., Ltd. v. Kemper Nat. Ins. Co.,
B.
Pursuant to the insurance policy, United National agreed to “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.” J.A. at 63. The policy provides that “advertising injury” applies to “an offense committed in the course of advertising [SST’s] goods, products or services,” and is defined as “injury arising out of one or more of the following offenses”:
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;
b. Oral or written publication of material that violates a person’s right of privacy;
c. Misappropriation of advertising ideas or style of doing business; or
d. Infringement of copyright, title or slogan.
J.A. at 63, 68. The term “personal injury” applies to injury arising from, inter alia, “[o]ral 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” or “[o]ral or written publication of material that violates a person’s right of privacy.” J.A. at 70. The policy also lists various exclusions from coverage. The policy does not refer to trademark, trade dress or patent infringement in defining coverage or in setting forth the exclusions from coverage.
C.
We are faced with an issue of first impression in this case, i.e., whether allegations of patent infringement constitute “an offense committed in the course of advertising [an insured’s] goods, products, or services” as defined by the insurance policy. On appeal, SST asserts that the policy language is ambiguous, Precise’s complaint alleges offenses which constitute “advertising injury” or “personal injury” pursuant to the policy, and United National has a duty to defend. Conversely, United National contends that the policy language is unambiguous, Precise’s allegations of patent infringement do not constitute “advertising injury” or “personal injury” as contemplated by the insurance policy, and it has no duty to defend SST in the underlying litigation.
The parties agree that Ohio law governs our interpretation of the insurance policy. Under Ohio law, the construction of an insurance contract is a matter of law for the court. In interpreting the insurance policy, “words and phrases used in an insurance policy must be given their natu
*450
ral and commonly accepted meaning.”
United States Fidelity & Guar. Co. v. Lightning Rod Mut. Ins. Co.,
In construing a commercial general liability insurance policy, we are also “required to consider the allegations pleaded in the [underlying] action in the light of the coverage provisions and exclusions in the policy[.]”

We are substantially aided in our inquiry in this case by two of our prior decisions-Advance
Watch
and
ShoLodge, Inc. v. Travelers Indem. Co.,
*451
SST, however, contends that
Advance Watch
is not “controlling precedent” because the rules regarding the interpretation of insurance polices under Ohio law are different from the rules under Michigan law. We disagree, and find that SST’s attempts to distinguish Ohio contract law from Michigan contract law are unavailing. Indeed, we rejected a similar claim by the insured in
ShoLodge
and concluded that “there is no material difference between Michigan and Tennessee law regarding principles of insurance contract interpretation.”
Id.
at 259. Moreover, a review of the overarching principles of insurance contract interpretation under Michigan, Tennessee and Ohio law clearly shows otherwise, for in all relevant respects, each state’s rules of contract interpretation are the same.
Com/pare Advance Watch,
Further, we emphasize that Precise’s complaint alleges
patent
infringement, which is clearly less related to even a broad notion of “advertising” than are trademark and trade dress infringement.
See Advance Watch,
Courts in other jurisdictions have reached conclusions similar to that reached in
Synergystex. See, e.g., Simply Fresh Fruit, Inc. v. Continental Ins. Co.,
We find the reasoning in these cases persuasive. In attempting to distinguish this line of cases, SST points out that unlike those cases, here, Precise specifically alleges that SST’s advertising infringed its patent, and that SST induced others to do so. However, the mere fact that Pre *452 cise uses the word “advertises” in its complaint is not dispositive, for we must still view that complaint in light of the language of the policy in determining whether United National has a duty to defend. Precise’s complaint, at its essence, merely alleges patent infringement, not an “advertising injury” of the type addressed by the parties’ commercial general liability insurance policy. Accordingly, we hold that patent infringement does not fall within the ambit of “advertising injury” as defined by the policy. 2
E.
SST also alleges that Precise’s allegations of injury to the Precise name, business reputation and goodwill constitute “personal injury” as defined by the insurance policy. SST’s argument on this point is unpersuasive. SST has failed to establish that the allegations in Precise’s complaint constitute libel, slander, invasion of privacy or disparagement as contemplated by the “personal injury” provision of the insurance policy. Finally, SST asserts that United National had a duty to defend against Precise’s unfair competition and unjust enrichment claims. SST has failed to point to any language in the policy which would impose upon United National a duty to defend against these two claims, and we decline to read such an obligation into the policy.
III.
For the reasons set forth above, we find that, as a matter of law, United National has no duty to defend SST in the underlying litigation. Accordingly, we AFFIRM the judgment of the district court granting United National’s motion for summary judgment.
Notes
. SST devotes several pages of its brief to discussing the declaration of its expert, Pete Ligeros. However, because we find that the language ol the policy is unambiguous, we will not consider extrinsic sources in interpreting the insurance policy.
. We also note that had the parties intended for "advertising injury” to apply to patent infringement, they easily could have included such language in the definition of the term.
