Legal Analysis
Policy Interpretation Challenges
Insurance policies surrounding patent infringement are often drafted narrowly, with explicit exclusions for intentional or willful infringement. Courts examine the language carefully to determine whether the insurer's obligations extend to defense costs.
Key case law references:
- Stempel v. State Farm Fire & Casualty Co. (2010): Emphasized strict construction of policy language.
- Travelers Cas. & Sur. Co. of America v. Malkin (2020): Clarified ambiguity in the definition of covered claims.
Coverage vs. Exclusion Controversy
In this case, the primary contention hinges on whether the patent infringement suit qualifies as a covered claim. Arthrex argues that the costs fall within the policy's "Defense of claims" clause, which is broad and includes patent-related litigation.
Contrarily, National Union contends that specific exclusions for patent claims or intentional misconduct apply, restricting coverage.

FAQs
1. What are typical policy exclusions for patent infringement claims?
Most policies exclude coverage for willful or intentional infringement, defamation, or fraud, often specifying that covered damages exclude punitive or statutory penalties.
2. How do courts interpret ambiguous insurance policy language in patent cases?
Courts generally favor the policyholder, interpreting ambiguous provisions broadly to promote coverage unless specific exclusions clearly apply.
3. Can patent infringement defense costs be considered "litigation costs" under insurance policies?
Yes, if policy language explicitly or broadly encompasses legal defense expenses related to patent infringement.
4. What are the main risks for insurers in covering patent disputes?
High litigation costs, potential damages, and policy exclusions for intentional or malicious infringement increase insurer exposure.
5. How do emerging patent enforcement trends affect insurance coverage?
Increased patent enforcement and litigation heighten insurer caution, leading to more restrictive policy language and exclusions.
