The Clearing House Association, along with SIFMA, filed an amicus brief with the U.S. Supreme Court in support of Microsoft's petition for a writ of certiorari. Microsoft is asking the Supreme Court to overturn the Federal Circuit's "clear and convincing" evidentiary standard. The brief argues that the financial services industry is disparately impacted by the Federal Circuit's evidence standard because patents are still new to the industry, and therefore many patents are granted despite the existence of invalidating evidence that was either not brought before, or not considered by the PTO during examination.
