Professor Sean Tu returns to talk to Chris and Megan about his research into what drives examiner behavioral patterns. His previous research revealed pockets of fast-moving and slow-moving examiners, but now he aims to answer the question "how are applicants and examiners slowing the prosecution process"? To answer this question, Professor Tu has conducted an in-depth, manual analysis of hundreds of applications from technology center 1600. In this episode, he shares the initial results of this analysis, including what types of rejections slower examiners typically issue, how many rejections they issue, and whether their applications are mostly original filings or continuations.
