Title 35 › Part III— PATENTS AND PROTECTION OF PATENT RIGHTS › Chapter 31— INTER PARTES REVIEW › § 316
The Director must create clear rules for how inter partes reviews work. The rules must make the case file public unless someone files a motion to keep a paper sealed while the motion is decided. The rules must say how to start a review, how to add extra information after a petition, how the review fits with other patent matters, and limits on discovery (mainly depositions of people who gave written statements and whatever else is needed in the interest of justice). The rules must allow protective orders for secret info, punish misuse of the process, let the patent owner file a response with affidavits or expert statements, let the patent owner ask once to cancel claims or propose a reasonable number of replacement claims (and make any amendment info public), give either side a right to an oral hearing, set a time to ask to join a case, and give the petitioner at least one chance to file written comments. The final decision must be issued within 1 year after the Director starts the review, but the Director may extend that by up to 6 months for good cause and may change timing for joined cases. The Director must think about the economy, patent system integrity, Office efficiency, and the Office’s ability to finish reviews on time when making the rules. The Patent Trial and Appeal Board will run each review. The patent owner may file only 1 motion to amend during a review unless both sides agree or the rules allow more. Any amendment cannot broaden claims or add new material. The petitioner must prove unpatentability by a preponderance of the evidence (more likely than not).
