What Is Intellectual Property Insurance?
Intellectual property insurance comes in two separate parts: defense, when you're accused of infringing a patent, trademark or copyright, and enforcement, when you pursue someone who copied yours. A defense-only quote doesn't pay for your own lawsuit, so ask for each part you need. 10,11,12,13,14
Key Differences in Intellectual Property Insurance
Specific product and alternative structures
Marsh describes IP Protect as covering losses involving patents, copyrights, and trademarks, with trade secrets available by endorsement. It also lists defensive and offensive IP insurance, contingency cover, trade-secret value insurance, and IP-backed financing. Marsh McLennan Agency’s separate reviewed overview names IP liability as an executive/professional product but does not describe those structures or claim categories. A buyer deciding between dispute defense, enforcement costs, and financing should ask MMA which, if any, are available in its placement. 5 9
Policy issuer and placement scope
Marsh says IP Protect is backed by Ambridge Partners but the cited page does not clarify whether Ambridge is the issuing insurer or an underwriting manager; its other IP placements may involve different insurers. The MMA overview also does not identify an insurer or form. The shared Marsh name does not establish that products, underwriting, or placement teams are the same. Request the exact legal issuer, policy form, and whether trade-secret protection is included or endorsed for the proposed account. 5 9
