Dr. Arthur M. Keller serves as a technical expert witness on patent infringement litigation, as advisor and board member to startups, and as a lecturer and researcher at the University of California at Santa Cruz. He was previously a researcher and lecturer at Stanford University. His expertise includes databases, electronic commerce, software, and Internet technologies. (He can also help you find another expert if your case is not within his expertise.) He has worked on both plaintiff cases, testifying on both validity and infringement, and defense cases, testifying on both invalidity and non-infringement. He has testified at deposition, Markman tutorial, and trial, including videotaped testimony, testimony before a judge, and testimony before a jury, including in the Eastern District of Texas. He has written expert reports on infringement and validity, and invalidity and non-infringement, as well as declarations in support of motions and claim construction. His testimony has never been limited from Daubert sanctions or motions in limine. He has also worked on declaratory judgment cases. His expert work has often resulted in favorable settlements without the need to go to trial.
