Definition:Patent infringement
⚖️ Patent infringement occurs when a party makes, uses, sells, or imports a patented invention without the patent holder's authorization — and in the insurance context, it represents a category of intellectual property exposure that can generate both first-party defense costs and third-party liability for policyholders across technology, manufacturing, pharmaceutical, and increasingly insurtech sectors. Standard commercial general liability policies typically exclude patent claims through intellectual property exclusions, which means businesses must turn to specialized IP insurance products for meaningful protection.
🔍 Coverage for patent infringement generally comes in two flavors. Defensive, or "abatement," policies reimburse the insured's legal costs when it is accused of infringing someone else's patent — a scenario that has become alarmingly common as non-practicing entities ("patent trolls") target companies across industries. Offensive, or "pursuit," policies fund the insured's litigation to enforce its own patents against infringers. Underwriters evaluating these risks examine the strength and scope of the patent portfolio, the litigiousness of the industry, the jurisdiction (U.S. patent litigation costs can reach tens of millions of dollars), and any prior claims history. Premiums tend to be high relative to other specialty lines because patent cases are complex, slow-moving, and unpredictable in outcome.
💡 The relevance of patent infringement to the broader insurance industry has grown sharply as carriers and insurtechs themselves develop proprietary technologies — AI-driven pricing models, telematics platforms, blockchain-based smart contracts — that may inadvertently infringe existing patents or become targets for enforcement actions. Beyond insuring others, insurers must manage their own patent exposure through internal risk management programs. For brokers advising clients, understanding the nuances of patent infringement coverage — including how retentions, policy limits, and choice-of-counsel provisions interact — is critical to placing effective programs in a market where capacity remains limited and claim severity continues to escalate.
