Successful Patents & Patent Stories

We have seen many successful patents over the years. Years of market presence has turned Patentest, together with its subsidiaries, from a small and revolutionary patent information company into a leading company in its field. Besides growing interest from media sources, Patentest is today a center and the first choice for many inventors in Sweden, Israel, UK, Germany, other Nordic and European countries. As such we serve many professional companies in our sector such as patent law firms, development and engineering companies, and financial institutions seeking to verify their investments.

In order to inspire inventors, startups and companies we have decided to share some successful patents here on our website. We aim to inspire inventors to come up with the next success story and business model. We hope this will help create the opportunities for new involvements and connections between inventors and investors.

If you have a success story you wish to share with us and publish on this page, please contact us and we will be happy to hear more about it. Now, let’s dive into a handful of particularly interesting inventors and patents.

European Inventor Award 2019 and 2020

The European Patent Office (EPO) awarded extraordinary inventors from France, Japan, Austria, Spain and the Netherlands.

The inventors were acknowledged for their extraordinary achievement in the area of plastic recycling, rechargeable battery technology, cancer diagnostics, DNA testing, marine antifouling.



Invention and patent for higher-performance plastic recycling

By thinking in a new direction, these Austrian inventors reshaped plastic recycling with their highly successful patent. With their approach, waste plastics of many types can be turned into high quality pellets for new products. Today, more than 6 000 of their machines in operation worldwide produce over 14.5 million tonnes of plastic pellets annually.

Margarita Salas Falgueras (Spain)

DNA amplification for genomics

The Spanish molecular genetics pioneer invented a faster, simpler and more reliable way to replicate traces of DNA into quantities large enough for full genomic testing, using the enzyme phi29 DNA polymerase. Her invention is now used widely in oncology, forensics and archaeology.
