He served as an Expert Witness on a Copyright and License infringement case involving software that finds deleted photographs on Flash Storage. He studied both sides source code and used standard evaluation techniques to establish that his client's code was not copied from the other code. After giving testimony in Federal Court in Florida, his client was found to be in the right and the case was won.He served as an Expert Witness putting together expert reports to opine if a certain game program infringed a Patent for the 3 dimensional representation of music.
He modified the scripting language to allow a video to made of the game while "flying" to the side and under a guitar fret, thus proving that the image was in fact 3 dimensional.He studied the use and operation of EDID data received from a computer display, to ascertain if his clients code infringed a patent claiming that the data was transmitted at power up time. Using a logic analyzer he was able to capture and translate the date stream to prove that the data was on transmitted by software request, not on power upHe performed a disk clone and forensic search of a disk drive to ascertain if the information pertaining to a mal-practice suit existing on a disk drive. Using Encase and writing an expert report, he convinced the jury that no such information was on the computer system of the client.He successfully argued against a patent during a deposition, showing the the software algorithm used to detect an off balance condition in a washer dryer was fundamentally different from the patent.
