Study for US Congress outlines options against patent trolls (The H)

The H takes a look at a report from the US Congressional Research Service about patent trolling and potential fixes to the system. "According to the researchers, it is worth considering whether to generally shorten the periods of protection for software patents because the trolls file most of their litigation claims in the last three years of the 20-year term. A patent could also be invalidated if it hasn't been practised for a number of years, they added."
