Number of patent families filed with different patent authorities vs. earliest priority year.
Summary
[edit]
| Description |
English: exemplary search string for patent families, which had at least one document published by the USPTO, and which have an earliest priority year in 2000: EPRD=2000 AND (US)/PN.
These data are subject to sampling bias. For example, there are more data for Spain for the 1800's than for the USA, because the Spanish Patent Office did a better job in digitizing and cataloguing its data. |
