Patent Index 2019

Quality indicators

Timeliness of patent grant procedure

Up until 2019, the EPO used median averages to indicate the timeliness of search, substantive examination and opposition procedures. From 2020 on, the EPO will use mean averages to indicate the timeliness of these procedures. This gives a more precise measurement of timeliness as it takes outliers into account.
To ensure transparency, historical data on the development of median and mean averages are provided. These illustrate how excessive procedural delays are being progressively eliminated.
An integral part of quality is the provision in good time of searches, examinations, and opposition decisions.
