The US Supreme Court at a session on Monday will hear Microsoft call to change patent law in a way that could help both the Windows developer and many other technology firms fend off patent troll lawsuits. The motion will attempt to change a rule that requires a defending company provide absolute, definitive evidence that a patent is invalid in order to avoid a guilty verdict. Under Microsoft's proposal, courts could invalidate patents only by requiring that the majority of evidence supports rejecting the patent.
