    Abstract: Recognizing the increasing accessibility and importance of patent data, the paper underscores the need for standardized and transparent data analysis methods. By leveraging the BigQuery language, we illustrate the construction and relevance of commonly used patent indicators derived from Google Patents Public Datasets. The indicators range from citation counts to more advanced metrics like patent text similarity. The code is available in an open Kaggle notebook, explaining operational intricacies and potential data issues. By providing clear, adaptable queries and emphasizing transparent methodologies, this paper hopes to contribute to the standardization and accessibility of patent analysis, offering a valuable resource for researchers and practitioners alike.

  2. By: Robin Kaiji Gong; Yao Amber Li; Kalina Manova; Stephen Teng Sun
    Abstract: We investigate how international patent activity enables firms from emerging economies to thrive in the global marketplace. We match Chinese customs data to US patent records and leverage the quasi-random assignment of USPTO patent examiners to identify the causal effect of a US patent grant on the subsequent export performance of Chinese firms. Successful first-time patent applicants achieve significantly higher export growth, compared to otherwise similar first-time applicants that failed. This effect operates only in small part through market protection for technologically patent-related products in the US and is largely driven by expansion in other markets. The response across destinations and products reveals that a US patent award signals the Chinese firm's capacity to produce high-quality products and credibility to honor contracts, mitigating information frictions in international trade. There is little evidence for the relaxation of financial constraints or the promotion of follow-on innovation.
