Which technologies are gaining patent activity, where, and who files the most? This page reads aggregate tables built from worldwide patent publications in the Google Patents Public Datasets. It shows technology class momentum (CPC classes), the patent offices publishing them, the share of grant documents, citations, and the top organisations. No inventor names and no individual applicants are included.

Each bubble is a CPC class (min. 1,000 publications in the start year of the range). Right = larger; up = faster growth (compound annual growth rate between the two selected years). Hover for the title; click a bubble to open the class below.
Offices marked "incomplete in source" published far fewer documents in the end year than in the three years before; this is a gap in the public source for that office, not a real collapse, so no growth rate is shown.
