At the time the Supreme Court heard the case, the lower courts had upheld the patent's validity under scrutiny. The case raised critical issues regarding the interpretation of patent claims and their standing against prior art.
The standard of review applied was de novo for legal conclusions concerning the patent's validity while giving deference to factual determinations made by the lower courts.
The Supreme Court concluded that the patent was not valid due to its failure to meet the necessary originality and non-obviousness standards.
