On January 30, 2016, I reported about Ubisoft opposing registration of EA's trademarks for the Ghost studio. New documents dated February 24, 2016, show that Electronic Arts has abandoned at least one of these trademarks. The below is for US Ser. No. 86/568,854, Ghost, under goods and services "Computer game software". The other trademark, US Ser. No. 86/568,852, Ghost, under goods and services "Entertainment services, namely, providing an on-line computer game", appears to still be in force, but ought to likely be withdrawn soon as well.
Ghost Games is the EA studio known for Need for Speed Rivals (2013) and Need for Speed (2015). They are currently working on the next Need for Speed game.
Whether the name of the studio will be affected by this development is unknown.
