I spent a year being a part time expert witness. I got paid what seemed like a lot of money. But I was also examining the specific implementation details of avionics for their enhanced ground proximity warning system. The combination of understanding code, aircraft dynamics, and existing patents was complex. It was made more so by the attempt by other avionics manufacturers to design around the patents and write the code sufficiently differently.
