As a software developer, I become "that computer guy" to everyone in my family. Which means I know everything about everything wrt computers. Is this true in your experience? Do you think it's a good idea to have your run of the mill web developer creating device drivers for your embedded device? Why then, do you think it was enough for him to simply speak with "dozens of lawyers" rather than finding one that had both knowledge and experience dealing with the specific area of the law dealing with this issue?
