A big loss for Microsoft
Microsoft had appealed to the high court in a case involving its Word software program, arguing that i4i shouldn’t have won a jury verdict regarding a patent claim related to document editing. I4i obtained a $290 million judgment against Microsoft, as well as an injunction that barred sales of certain versions of Word said to infringe the patent.
The Supreme Court said a challenge to a patent claim “requires an invalidity defense to be proved by clear and convincing evidence.” Justice Sonia Sotomayor, writing the main opinion, said Congress set the standard in a 1952 patent law and that any “calibration of the standard of proof remains in its hands.”
In other words: you got a problem with this, take it up with Congress, not us.
