She has assisted in multi-million dollar IP due diligence projects during both the acquisition and divestiture of businesses, as well as coordinated multi-jurisdictional post-acquisition IP assignment programs, and provided IP auditing services to clients who have acquired large IP portfolios, including portfolios having in excess of 1,000 rights.
