Furthermore, Mr. Ludwig’s trial resume also includes numerous complex felony criminal matters, often involving fraud. The end result of such experiences has allowed Mr. Ludwig to try nearly two dozen cases to jury verdict, while serving clients who run the gamut from individual inventors and entrepreneurs to start-up ventures and Fortune 100 companies in matters arising in the U.S., Europe, Asia, and India.
