He was lead counsel before the Florida Supreme Court on behalf of the Florida Motion Picture & Television Association, challenging the prima facie constitutionality of a proposed sales tax on commercial speech. Later, he was appointed a Special Deputy AG for the State of Washington to argue before the Alaska Supreme Court.

In Silicon Valley he has been General Counsel for public, private and non-profit companies. He has testified before the California Assembly and the House Subcommittee on Science and Technology on software issues, and as an expert witness on intellectual property in United States District Court. His thesis for the JSM at SLS explored the applicability of software design methodologies to law- and policy-making.
