One option is judicial activism. This year, Judge Posner, in an Illinois federal court, tossed out patent arguments made by both Apple and Motorola Mobility in a 38-page opinion that dismissed a lawsuit between the two companies. Cleaning up the patent mess, Judge Posner said in an interview, might also require reducing the duration of patents on digital technologies, which can be as long as 20 years.
“That would make a big difference,” he said. “After five years, these patents are mainly traps for the unwary.”
