In addition to intellectual property, Dan has also litigated contract, securities, and antitrust cases.

He has represented clients in angel, VC, M&A, and IPO transactions, negotiated sales and licenses of intellectual property, and advised on intellectual property infringement, validity, and valuation issues. A registered patent attorney, Dan has also procured patents, trademarks, and copyrights for clients.
