Correction: Corrigendum: The Gender Patenting Gap: A Study on the Iberoamerican Countries

On section 3, first paragraph, the sentence “The extraction was done on November 20, 2019.” was added. This informs the baseline date for the data collection, allowing the experiment to be reproduced by choosing the appropriate data from PATSTAT. In the previous version of the paper, some of the data was taken from a different date, as the study was refined over a few months, causing the final results to be difficult to reproduce precisely. For this reason, we fixed this date and ran all the calculations on this baseline. This caused small changes in the tables (1, 2, and 3) and in Figure 3, which are detailed in the next points.

In Table 1, the number of inventors and respective “Avg. women p/patent” and “Avg. women invt. ratio” changed for the following countries:

• Belize: 25 to 26, unchanged, unchanged

• Cuba: 1547 to 1556, 0.664 to 0.672, 0.437 to 0.440

• Dominican Republic: 145 to 148, unchanged, 0.255 to 0.250

• Portugal: 9086 to 9129, 0.460 to 0.465, 0.265 to 0.267

• Latin America: 60012 to 60016, unchanged, 0.228 to 0.227

• Iberian Countries: 104088 to 104131, 0.443 to 0.446, 0.274 to 0.275

• Ibero-America: 164100 to 164156, 0.657 to 0.658, 0.231 to 0.232

Also in Table 1, the “percent” column in Table 1 was mistakenly calculated using the entire set (150,863 patents) instead of the filtered set (103,914). We fixed that so the percent values now match correctly the patent numbers in the “# of patents” column.

The updated table is as follows:

In Table 2, the numbers were truncated to the 3rd decimal place, and the number of inventors and respective “Avg. women p/patent” and “Avg. women invt. ratio” were changed as follows:

• COMPANY: 150,796 to 150,866, unchanged, unchanged

• GOVERNMENT: 21,094 to 21,126, unchanged, unchanged

• INDIVIDUAL: 6,412 to 6,421, 0.190 to 0.194, 0.192 to 0.193

• UNIVERSITY: 27,990 to 28,006, 0.641 to 0.635, 0.405 to 0.404

The updated table is as follows:

In Table 3 one row was changed as follows:

• Portugal: 0.226 to 0.228, 0.301 to 0.302, 0.076 to 0.074

The updated table is as follows:

Figures 1 and 2 were not changed due to truncation of small numbers. The updated Figure 3 is as follows:
