Ripasso Energy strengthens patent and product protection

Ripasso Energy AB is set to tighten its product protection with the intention of developing its portfolio of patents to cover parts of the PWR BLOK 400-F. The company has previously submitted three patent applications related to the hybridisation function of its Stirling engines.

The board of Swedish clean tech company Ripasso Energy AB plans to expand its patent portfolio. The company previously applied for 3 patents, all of which were related to the hybridisation function of its Stirling technology. The company now intends to protect the technology behind the PWR BLOK 400-F - the unique container-based solution in which the company’s Stirling engines are used to harness energy from residual gases.  

Ripasso Energy will initially limit the applications to patents that the company deems itself capable of defending in the case of infringement. The board and the CEO will however continuously monitor the protection and strengthen it in tact with increases in sales.

“As the PWR BLOK will soon be going to market, it’s a natural step for us to begin the process of seeking protection for the parts of the technology that will now be public,” says Gunnar Larsson, CEO of Ripasso Energy.
