Crunchfish Digital Cash AB has received an International Preliminary Report on Patentability (IPRP) in Chapter II of the Patent Cooperation Treaty (PCT) for a key Digital Cash patent application PCT/SE2022/050152 indicating that all claims 1 - 39 are deemed patentable. The main claim of this patent has very broad applicability as it protects many aspects of non-native layer-2 offline payment solutions in addition to its focus on domestic and international interoperability between CBDC-, Real Time Payment- and Closed Loop Wallet- payment service applications. The patent protects how CBDC-Retail applications issued by the central bank may become interoperable with other payment service applications in the same country as well as how CBDC-Retail applications from multiple countries, multi-CBDC or mCBDC, can interoperate.

It also covers interoperability between Closed-Loop Wallets and Real Time Payments applications domestically as well as internationally. Furthermore, the main claim of this patent is broadly defined protecting many aspects of non-native layer-2 offline payment solutions in general, in addition to its focus on interoperability. This makes this Digital Cash patent a key strategic asset for Crunchfish which it is likely to nationalize in many countries world-wide during the nationalization phase within 6 months.
