Welcome to our digital museum!

Here you will learn about the great inventors, technical breakthroughs and innovative companies we have been involved with since 1869.

Our history reflects the industrial development that has taken place in society at large – through depressions, world wars and IT-bubbles.

Welcome to experience the development from the dynamite to cryptocurrencies.

1869

Patent Pioneer: L A Groth

Lorenz Albrecht Theodor Groth founded Groth & Co in Stockholm in 1869. As Scandinavia’s first patent agency, he offered to “assist inventors with registering patents”, but also to commercialise the patents and sell the products.
