This table shows the number of patents granted by country or type submitted to ERA 2015 for the reference period. For ERA 2015, the reference period for patents was 1 January 2011–31 December 2013.
Patents granted in Australia, United States, Europe, and Japan are reported in ERA 2015. Patents granted in other jurisdictions are grouped into the ‘other international’ category. Triadic patents are a series of corresponding patents filed at the European Patent Office (EPO), the United States Patent and Trademark Office (USPTO) and the Japan Patent Office (JPO), for the same invention by the same applicant or inventor. Institutions were required to identify patents that are essentially the same patent registered in more than one country–the ‘patent family’ column displays a set of unique patents.
