New working paper alert: "Financing Innovation: The Role of Patent Examination". @steve-bill-econ.bsky.social, Christopher Coyle and I have been working on this for quite a while now. We are excited to have a full draft for your enjoyment! www.quceh.org.uk/uploads/1/0/...
Financing Innovation: The Role of Patent Examination.

Stephen D. Billington, Christopher L. Colvin and Christopher Coyle.

How does patent examination influence access to finance for innovative firms? We exploit a reform to the UK’s patent system that introduced substantive examination to the patent application process, improving the information available to potential investors on the value of firms’ patents. Using a newly compiled firm-level dataset of exchange-listed corporations, we find that firms holding examined patents were able to borrow more, reflecting improved access to capital markets, and leading to firm growth. Our results highlight the role of patent examination in reducing information asymmetries, enhancing the signalling value of patents, and mitigating financial barriers to innovation.
