AcouSort receives Notice of Allowance in the US for patent on plastic chips


The US patent authorities, USPTO, have issued a Notice of Allowance for one of AcouSort’s patent applications. The patent covers how to design and drive acoustofluidic devices made in plastic. The invention was originally acquired from the Technical University of Denmark (DTU) in 2018.

In 2018 AcouSort acquired an invention from DTU that describes a new way of designing and operating acoustofluidic devices made of soft materials such as polymers, in order to be able to replace components made of silicon or glass.

Since the acquisition of the patent rights from DTU, AcouSort, Lund University, DTU and the Danish company Ortofon have jointly worked on developing practical designs and methods for producing polymer based devices through the AcouPlast project supported by Eurostars/Vinnova.

Together with another invention concerning a new and more efficient way of manufacturing AcouSort’s acoustic chip, which AcouSort acquired from DTU in 2021, separation modules will be easier to manufacture at high volumes in a more cost-effective way. It will take at least 3-4 years of further research and development before the new type of plastic chip acquires a commercial significance.

– The business potential of making separation modules in plastic instead of glass should not be underestimated, especially in combination with the second invention that we acquired from DTU, targeting how to produce ultrasound in a more inexpensive way. The road is now paved towards producing low-cost separation modules enabling the application of one-time-use consumables. Such consumables are most often required when handling blood samples from patients in primary care or therapeutic settings in order to avoid potential cross contamination between patient samples, says AcouSort’s CEO Torsten Freltoft.
