Crunchfish receives Patent Notice Regarding a Privacy and Interoperable Offline Payment Innovation
Crunchfish Digital Cash AB ("Crunchfish") has received a Final Notice from the Swedish Patent Office (PRV) for a privacy and interoperable offline payment innovation, where the payee does not have to be onboarded to receive the payment. This is a divisional patent application with priority from the underlying patent application filed in November 2021. The patent is valid until November 2041, 20 years from the original filing date.
Crunchfish is pleased to announce that the Swedish Patent Office (PRV) has issued a Final Notice that they intend to grant Crunchfish a patent for divisional patent application number 2350084-6, wherein a signed offline payment by either the payer or the issuing payment service provider on behalf of the payer may be verified by the payment network or the issuing payment service provider by means of a root digital certificate of a certificate authority (CA), independent from the entities of the digital payment system.
The innovation enables transaction privacy for the payer with respect to the whole payment ecosystem, save for the issuing bank, as payments may be signed out by the issuing bank on behalf of the payer. Another valuable aspect is that payees may receive offline payments without taking any preparatory steps to become onboarded to the offline payment system.
"This is an interesting payments innovation that allows the payer to be private in relation to the whole payment ecosystem except the issuing bank. It also supports offline payments interoperability - cross-service, cross-network, and cross-border - even if the payee is not yet onboarded to the offline payment system. By the virtue of the grant in Sweden, our hopes for grants in other jurisdictions increase considerably", says Joachim Samuelsson, CEO of Crunchfish.
The underlying patent application with priority from November 2021 has already been granted in Sweden with patent number 546 821, and is in the process to be nationalized in Europe, USA and India.
