题目：From Choice to Race: The America Invents Act and Strategic Patent Filing Behavior

摘要：

The America Invents Act (AIA) of 2013 transitioned the U.S. patent system from first-to-invent (FTI) to first-inventor-to-file (FITF), fundamentally altering firms’ strategic patenting incentives. Using USPTO application and grant data from 2003 to 2022, we exploit the fact that foreign-first filers were already subject to first-to-file rules as a natural control group within a difference-in-differences framework, complemented by event-study and survival analyses. We document four findings: a sharp pre-AIA filing surge driven by strategic timing; a post-AIA narrowing of claim scope as firms sought to improve approval odds; the highest application quality in the pre-AIA period, as those filings were least likely to be abandoned or rejected; and substantial firm-size heterogeneity, with large firms dominating the filing surge while small firms faced higher post-AIA abandonment and rejection rates, despite their granted patents attracting more forward citations. These results provide causal evidence on how patent policy reform reshapes innovation incentives and outcomes unevenly across firms.
