David Tollen serves as an expert witness in litigation related to information technology contracts and relationships. He addresses industry custom and practice and legal issues surrounding software-as-a-service (SaaS) agreements, other cloud computing transactions, software licenses, IT professional services, e-commerce, data security, and other topics.
Many patent licensing experts testify about IT contracts — and neither they nor their clients realize that patent licensing and IT contracts are separate fields. Expertise on patent licensing does not translate into expertise about software licensing, cloud computing agreements, or other IT contracts. David Tollen is not a patent licensor branching out into another field (though he does have broad patent licensing experience). His book, The Tech Contracts Handbook, is about IT contracts, and that is his specialty.
