Microsoft launches patent tracking system that could foil trolls

Tool makes it easier to prove ownership

Microsoft is fighting patent trolls with the weapon it knows best—technology.

On March 28, the company launched Patent Tracker, a tool that holds a searchable database of all Microsoft’s patents. Users can search for patents by title, number or assignee of record. The advantage this gives to Microsoft is that it can clearly show ownership, making it more difficult for trolls—who buy up patents just to litigate them and rake in big bucks—to follow their established patterns.
