You cannot dismiss a jury member's own experiences from their decision making process. It was the attorney's job to vet for the jury for problematic backgrounds, and to toss out those that they were concerned about. The fact that this person was on the jury tells me that they were comfortable with his background.

Also, four of the jury members work for high tech companies, including Intel, AT&T, a circuit board manufacturer, and a hard drive company. So while the foreman was unique in that he holds a patent, many of the jurists have had at least some exposure to technology products in their professional careers.
