The invention in question describes the operation of a network interface with independent management of the buffer of the machine containing an Ethernet adapter. It was awarded to another company (3Com Corporation) in 1994, but because it acquired ownership rights years later, US Ethernet Innovations claims that it was being violated by Apple to this day due to a lack of license or permission to use .
Interestingly, only the MacBook Pro was listed as a product that violates such a patent, but there are many products from other companies involved in the pie. Only the list of manufacturers without including Apple is already huge: it includes Acer, ASUS, Dell, Fujitsu, Gateway, HP, Sony and Toshiba.
