Expert witness: on two occasions I have provided information for legal actions. One is still sub judice, the other involved a patent infringement complaint, where one company claimed to own the rights to a particular circuit configuration. I was able to show that the circuit had been documented some years prior to the patent application being filed.
Documentation: test specifications, approval documentation, user documents and engineering reports
