The Supreme Court affirmed the USPTO Board's decision to invalidate claims in Cuozzo's speedometer patent. The Court held that the Board's decision to institute IPR of dependent claims not explicitly challenged in the petition was not appealable. The Court also upheld the Board's use of the "broadest reasonable interpretation" standard for construing claim terms during IPR, rather than the narrower standard used in district court. The decision increases the USPTO's power to reconsider and invalidate issued patents through the IPR process.
