A PlayStation cartridge patent has been registered by Sony Interactive Entertainment earlier this year at the Instituto Nacional da Propriedade Industrial (INPI) in Brazil, as spotted by Dutch website LetsGoDigital. Sony used Kasznar Leonardos as the local 'IP agent' to submit the application.

The design of this PlayStation cartridge was realized by Yujin Morisawa, Senior Art Director at the Corporate Design Center of Sony Interactive Entertainment and responsible for all products associated with the PlayStation brand. In his 15 years with Sony, Yujin has designed products in various fields - from cosmetics and electronics to the Agent robot (via iF World Design Guide).
