Matching USPTO Patent Assignees to Compustat Public Firms and SDC Private Firms

This data project is a systematic effort to match assignee names on USPTO patent records, sometimes abbreviated or misspelled, to all public and private firms that have been involved in alliances and M&A in Compustat and SDC Platinum databases. The current coverage runs from 1976 to 2017 for all public firms in Compustat and from 1985 to 2017 for all private firms in SDC Platinum.

The algorithm leverages the Bing web search engine and significantly improves upon fuzzy name matching, a common practice in the literature. This document presents a step-by-step guide to the searching and matching algorithm. All codes are publicly available on the GitHub page:

This data is used in my job market paper "Technology Development and Corporate Mergers" and other projects including "Technology, Information, and Firm Boundary" (with Miao Liu). It will be made publicly available after the paper is published. I acknowledge the research grant from the Finance Division and the Deming Center at Columbia Business School.
