They tried but possibility of confusion may have stopped their effort:
The filing, which was filed in October last year, surfaced a few days ago through a NeoGAF member, and has since been denied by the USPTO on grounds of “likelihood of confusion,” due to a similar mark already being trademarked. Thanks to a trademarked service LP Let’z Play, Sony was denied.
- apparently Sony still can try something, if there is something to try:
Sony now has six months from the decision’s issue date, which was December 29, to address the refusal, providing “evidence as to why the refusal should be withdrawn.”
