Industry Comment

"I firmly believe that your character was the primary reason why the jury and the judge, who did not have sufficient patent experience and the technical understanding, were able to reach the fair and reasonable determination at trial. We believe that without your strong expertise and enthusiastic technical analysis in addition to your testimony that showed your sincerity at trial, we would not have been able to obtain a favorable verdict."
