Research and innovation in big data in the medical sector has declined in the last year.

The most recent figures show that the number of big data related patent applications in the industry stood at 25 in the three months ending April – down from 47 over the same period in 2021.

Figures for patent grants related to big data followed a similar pattern to filings – shrinking from 16 in the three months ending April 2021 to three 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.

Big data 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.

Johnson & Johnson was the top big data innovator in the medical sector in the latest quarter. The company, which has its headquarters in the United States, filed six big data related patents in the three months ending April. That was down from 10 over the same period in 2021.

It was followed by the Japan based Shimadzu Corp with four big data patent applications, Switzerland based F. Hoffmann-La Roche Ltd (3 applications), and the United States based Danaher Corp (2 applications).
