Dr. Keller serves as an expert witness on patent infringement cases and as advisor to startups. He has testified at trial, deposition, and Markman tutorial. He has also been a non-testifying expert. He has written reports on infringement and validity for plaintiffs and on invalidity and non-infringement for defendants. His expertise includes databases, Internet and electronic commerce. In a recent case on database systems, he succeeded in getting the case dismissed in a motion for summary judgment following a favorable Markman ruling. This dismissal was mostly affirmed on appeal, with the one remaining issue later resolved. In a recent e-commerce case, he was responsible for one out of the three patents in the suit, and succeeded in getting this patent ruled invalid. In this same case, he testified on the invalidity of another of the patents in suit. While the jury found that this patent was valid and infringed, the U.S. Court of Appeals for the Federal Circuit's ruled that the patent was invalid based on his article.
