  • Fig. 1 Connectivity and distance.

    (A) The directed graph of the integrated citation network from patents toward papers defines a distance metric, Embedded Image. (B) The share of papers that link forward to a future patent and the share of patents that link backward to a prior research article. (C) The distance distribution of connectivity.

  • Fig. 2 Application to fields.

    (A) Distance metric. The mean distance, Embedded Image, to the paper-patent boundary is presented for each field (x axis) together with the percentage of knowledge outputs in that field that are connected to the integrated citation network (y axis). (B) The full Embedded Image distribution for several fields.

  • Fig. 3 Distance and impact.

    (A) Impact close to and far from the paper-patent boundary. A “home run” is defined as being in the upper 5% of citations received in that field and year, for a patent or a research paper. (B) Home-run outcomes relative to distance for each field, when each field is analyzed separately. The supplementary materials examine alternative impact measures, including methods based on patent-renewal payments.

  • Fig. 4 Institutions and individuals.

    (A) The Embedded Image distribution for different institutional settings, including universities, government laboratories, and firms. (B) Production of patents and papers by institutional type at the Embedded Image boundary. (C) The share of Embedded Image patents where a citing inventor and cited author have the same name, by patent assignee type.
