Juristat

Juristat analyzes USPTO data to help patent practitioners improve prosecution outcomes. It provides detailed analytics on patent examiners — their allowance rates, common rejections, average office actions, and response strategies that work best with them. This lets you tailor arguments to specific examiner tendencies. The platform also analyzes art unit performance, continuation strategy effectiveness, and interview timing impact. It can predict the likelihood of allowance based on examiner, art unit, and claim characteristics. This is invaluable for large patent portfolios where strategic decisions compound. The main limitation is that it's backwards-looking — it tells you what has worked historically, not what will work for novel technologies. It's also expensive enough that it's primarily used by large law firms and in-house teams with significant patent volume.
