Six lawsuits a consumer brand with a marketing engine gets hit with. Click each one and see whether a standard general liability policy defends it... and notice which one it never does.
The two doors. Door A is bodily injury and property damage: someone got hurt. Door B is personal and advertising injury: someone says your words, pictures or ads hurt them. For a brand that markets, Door B is the one people knock on.
The named offenses. Libel, slander, disparaging a competitor, and using someone's copyright, trade dress or slogan in your advertisement. Inside those, the insurer has a duty to defend, and the duty to defend is broader than the duty to pay.
What is carved out. Trademark by default. Packaging, because the definition of advertisement excludes it. Patents, always. And failure to conform, the claim that your product does not do what the ad says, which is excluded from payout in essentially every policy and is the one a functional product is most likely to face.
This is education, not legal or insurance advice. A licensed agent reads your policy.
