Figures for patent grants related to AI followed a similar pattern to filings – shrinking from 2,221 in the three months ending September last year to 1,950 this year.
The figures are compiled by GlobalData. The research company tracks patent filings and grants from official offices around the world. Using textual analysis, as well as official patent classifications, these patents are grouped into key thematic areas, and linked to key companies across various industries.
AI is one of the key areas tracked by GlobalData. It has been identified as being a key disruptive force facing companies in the coming years, and is one of the areas that companies investing resources in now are expected to reap rewards from.
The figures also provide an insight into the largest innovators in the sector.
