Using China’s 2012 Fast-track Patent Applications policy as a quasi-natural experiment, this study examines how accelerated examination affects patent-grant decisions and claim scope. It identifies an “acceleration alignment”: examiners cite less prior art while applicants narrow claims more aggressively to secure faster grant.

This study explains the distinctive value of negative-result data for AI for Science and proposes an implementation framework encompassing data collection, contribution incentives, and iterative data–model feedback.

This study finds that early publication shortens patent maintenance duration, with knowledge spillovers and infringement risk serving as key mechanisms through which innovation value is eroded.

Examining the strategic use of early publication, this study finds that it may increase low-quality filings and create a policy-driven patent bubble.

Using an instrumental-variable approach and two-stage least squares, this study finds that early patent application publication reduces information asymmetry and significantly promotes technology transactions.

Using a patent dataset for China’s integrated circuit manufacturing industry, this study shows how foreign enterprises can use patent appropriability to create technological path dependence and lock-in.

Using fast-tracking patent applications as a quasi-natural experiment, we find that extending effective patent length stimulates corporate innovation and facilitates knowledge spillovers.

Using court decisions from across China, this study examines the evidentiary weight of patent technical appraisal opinions and offers institutional recommendations for commissioning, cross-examination, and professional oversight.

Combining logistic regression with a BP neural network, this study identifies the main determinants of patent profitability across applicant-, patent-, and event-level characteristics.
