The US computer and software giant is the latest in a string of major companies to take a licence to the standard essential patents offered through the programme. In doing so, it joins ASUS, Hewlett Packard Enterprise and Sony Group Corporation, as well as Huawei, Panasonic, Philips and ZTE which are also pool licensors alongside KPN, Mitsubishi Electric, Orange, Aegis 11 (a Sisvel affiliate), SK Telecom and Wilus.

STOKR Secures CASP and PI Licences in Luxembourg Ahead of MiCAR Deadline30.6.2026 11:00:00 EEST | Press release
STOKR, the Luxembourg-based digital securities platform, has received authorisation from the Commission de Surveillance du Secteur Financier (CSSF) under the EU's Markets in Crypto-Assets Regulation (MiCAR) and the Law of 10 November 2009 on payment services, securing its Crypto-Asset Service Provider (CASP) and Payment Institution (PI) licences just over a week before MiCAR's 1 July 2026 enforcement deadline. Digital securities fall outside MiCAR's scope but the payment leg does not. To receive, hold, and transfer crypto assets and stablecoins on behalf of clients during subscription and redemption, a platform requires a CASP licence under MiCAR and a PI. Without both, a platform can issue digital securities but cannot move the capital. With MiCAR's transitional period ending on 30 June 2026, a significant number crypto-asset providers across Europe are still awaiting the authorisation they need to keep operating in the EU, and many face suspending services. The authorisation grants S
