abstract = {Frakes and Wasserman (2020) finds evidence that United States Patent and Trademark Office (USPTO) patent examiners disproportionately receive credit for examination activities at the end of production periods and interprets this behavior as systemic examiner procrastination. Using newly assembled micro data on the
timing of USPTO examiner activities, our results show examiner work effort more closely resembles a uniform distribution over the production period, indicating consistent workflow and not procrastination. The assembled
data better track the precise timing of examiner work activities than the data used in Frakes and Wasserman
(2020), explaining the differences in our results. While Frakes and Wasserman (2020) conduct a thorough analysis of the markers and consequences of ??end-loading'', its use of an inadequate proxy for examination activity (i.e., Office action count dates) leads to incorrect conclusions about the examination process (i.e., widespread examiner procrastination)},

abstract = {We investigate how U.S. Patent and Trademark Office (USPTO) patent examiner experience and seniority-basedincentives affect the innovation ecosystem. First, we show that examiners respond to production incentivesand demonstrate learning by increasing the use of examiner's amendments in both experience and seniority,a mechanism not previously studied. Second, this examination procedure directly benefits innovators andfirms by significantly reducing prosecution processing time without impacting patent quality. Finally, afterconsidering examiner's amendments, the negative relationship between examiner characteristics and patentexamination quality found in the previous literature does not persist at first action, a decision point thatallows for the clear measurement of examiner behavior. Our results demonstrate a need for reformulatedpolicy recommendations related to the structure of examination at the USPTO.},

We argue that aggregate trademark data reflect firm-level choices that can help predict business cycles. In addition to establishing the conceptual basis for considering trademarks, our statistical evaluations, using turning point analysis and a novel machine learning method, find that trademark filings for product and service offerings in commercial use outperform many of the conventional leading indicators. Our work suggests that including trademark metrics in composite indexes could improve recession forecasting performance.},

abstract = {Clear and well-defined patent rights can incentivize innovation by granting monopoly rights to the inventor for a limited period of time in exchange for public disclosure of the invention. However, with cumulative innovation, when a product draws from intellectual property held across multiple firms (including fragmented intellectual property or patent thickets), contracting failures may lead to suboptimal economic outcomes. However, an alternative theory, developed by a variety of scholars, contends that patent thickets have a more ambiguous effect. Researchers have developed several measures to gauge the extent and impact of cumulative innovation and the various channels of patent thickets. This paper contends that mis-measurement may contribute to the incoherence and overall lack of consensus within the patent thickets literature. Specifically, the literature is missing a precise measure of vertically overlapping claims. We propose a new measure of vertically overlapping claims that incorporates invention similarity to more precisely identify inventive overlap. The measure defined in this paper will enable more accurate measurement, and allow for novel economic research on cumulative innovation, fragmentation in intellectual property, and patent thickets within and across all patent jurisdictions.},

This experiment, called the Pro Se Pilot, led to an 8 percentage point increase in the likelihood of receiving a patent. We exploit the random assignment of treatment to identify causal impacts of receiving a patent on short term independent inventor outcomes. Our results suggest that patenting is key to inventive, innovative, and entrepreneurial activity. We find large effect sizes of patenting on reducing financial frictions, participating in markets for technology (18.7 pp), and signaling inventor value to established firms (24.8 pp).},

Women applicants were 11 percentage points more likely than men to benefit from this assistance, and the benefits were largest for new inventors, and in areas of technology where women have the worst relative outcomes.},

For financially-constrained Pro se inventors from the USPTO experiment, patents act as a signal and increase the likelihood of affiliation. For the broader set of independent inventors, however, patents reduce financial, informational, and commercialization frictions and increase subsequent inventive activity.},
