What Intellectual Property Insurance Requirements Apply in Michigan?

Michigan’s trade-secret law permits injunctions against actual or threatened misappropriation, but the injunction ends when the information no longer qualifies as secret, subject to a period to remove the wrongdoer’s advantage. Ask how the policy handles urgent relief and follow-on damages.

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. Read the national Intellectual property guide.
