Research and innovation in industrial automation in the private banking sector has declined in the last quarter – but remains higher than it was a year ago.

The most recent figures show that the number of industrial automation related patent applications in the industry stood at 27 in the three months ending April – up from 17 over the same period in 2021.

Figures for patent grants related to industrial automation followed a different pattern to filings – shrinking from 37 in the three months ending April 2021 to 32 in the same period in 2022.

The figures are compiled by GlobalData, who track 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.

Industrial automation 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.

Berkshire Hathaway Inc was the top industrial automation innovator in the private banking sector in the latest quarter. The company, which has its headquarters in the United States, filed six industrial automation related patents in the three months ending April. That was up from three over the same period in 2021.

It was followed by the China based Jiangxi Bank Co Ltd with five industrial automation patent applications, the United States based Apollo Global Management Inc (2 applications), and the United States based The Allstate Corp (2 applications).
