Crunchfish

This patent encompasses numerous fundamental aspects of offline payment technology protecting Crunchfish’s signature layer-2 solution using a Reserve, Pay, and Settle approach. It allows transactions to be digitally signed by the payer from within a secure element – either hardware-based or software-based – provided there is sufficient funds in a reservation available online in the underlying layer-1 payment system. The transaction is then transferred to the payee for validation offline. Both parties retain a record of the digital transaction for subsequent settlement whenever either party regains online access.

“It is extremely gratifying that our foundational Digital Cash patent application for offline payments with priority dating back to early 2020 has also been granted in Taiwan, making it the third jurisdiction to do so, after the US and Europe. This development bolsters our optimism for favorable outcomes in India and China to come.” said Joachim Samuelsson, CEO of Crunchfish.

The patent application has already been granted in the US and Europe, and has received a positive International Preliminary Report on Patentability. Holding a patent in a country means that no entity is allowed to sell or market products that infringe upon this patent within its borders. Additionally, any entity based with this country is also prohibited from selling or marketing infringing products anywhere in the world.

Crunchfish is in the process of nationalizing patent applications in India and China for this innovation. In both cases, the examiners point to a patent application filed by Mastercard in 2018 as the closest prior art. However, Crunchfish has successfully demonstrated during the international patent process that there are significant differences between Mastercard’s 2018 and Crunchfish’s 2020 applications. A hearing in India is scheduled for the end of July, while communications with the patent offlice in China have thus far been conducted in writing.
