We posted last month about a Canadian company that lost a patent infringement suit in Texas to competitor Blackboard Inc.  The Canadians lost another round a few weeks later when the judge barred them from selling the infringing products in the US.  In a recent reversal of fortune, the U.S. Patent and Trademark Office has now issued a preliminary decision that rejects all 44 patent claims made by Blackboard Inc. in its software patent. 

This shows the value of a coordinated patent litigation defence – fighting the patent infringement claim both in the courts and in the USPTO.
