In approximately 22 cases, I have acted as an expert witness for patent infringement or product liability. So far, all but three of these cases were resolved pre-trial. In a 2008 patent infringement case that went to court, I was the key technical witness in a case where my client was awarded a substantial eight-figure judgment against the defendant, and in 2016 I was a key expert witness at a liability/injury trial where the plaintiff was awarded $1.8M in damages.
