[7] Before commencing legal action easyGroup's lawyers bombarded Easyart.com with threatening letters, despite having accepted £2,000 worth of advertising from the art company in its EasyInternet cafes not long after it launched.

"[16] In September 2018, easyGroup was taking legal action against Netflix over its comedy series Easy, claiming its use of the name breaches its European trademarks.

[20] In April 2022, Stelios Haji-Ioannou was described as a "deeply unimpressive witness" who gave answers "that were defensive to the point of implausibility" by a High Court judge who oversaw a trademark disagreement involving EASYOFFICE, owned by a company called Nuclei.

The judge, Mrs Justice Bacon, found in favour of Nuclei and said four easyGroup trademarks should be revoked on the "grounds of lack of genuine use".

As of 2024, easyGroup lists over 200 easy branded business ventures and websites in a wide range of sectors,[23] including easyJet and easyBus.

Amongst the ventures formerly owned by easyGroup which are still in operation under new full or partial ownership are hotel chain easyHotel, financial intermediary services brand easyMoney and African low-cost airline Fastjet.
