LMFAO is an American electro pop duo consisting of rappers, singer-songwriters, producers, dancers and DJs Stefan Kendal Gordy (aka Redfoo) and his nephew Skyler Austen Gordy (aka SkyBlu).The group formed in 2006 and their music incorporates a theme of partying and drinking, and the group commonly refers to their music style as "Party Rock". They have released two hit albums namely “Party Rock” (2009) and “Sorry for Party Rocking” (2011).

LMFAO attempted to register five trademarks, all of which included the band’s name, in early 2008 and 2009. Three of the applications were rejected by the examining attorney on a 15 USC §1052 (a) of the U.S. Trademark Act for consisting or comprising of immoral or scandalous matter (Ser. No. 77732029, 77732024, and 77692237). At this point, LMFAO and its attorney might have thought, “Well, they caught us and we all know what the “F” stands for and there’s no arguing about that.” The “F” in LMFAO could be said to consisting or comprising of immoral or scandalous matter, and the band might have thought that there wasn’t a way to argue against it.

An individual filled an application for the mark LMFAO (Ser. No. 85337050) in 2011. This applicant received an office action concerning to its meaning surprisingly not as to the scandalous nature of the mark! The examining attorney asked whether LMFAO had any significance in the industry for which the applied would use the mark (clothing).

LMFAO hired Alina S. Morris, a new attorney, and filed four new applications for the LMFAO mark on March 16, 2012. The attorney being proactive due to prosecution history of application for the mark LMFAO (Ser. No. 85337050, included the miscellaneous statement, “LMFAO stands for ‘laughing my freaking ass off” in recent trademark application.We wish LMFAO best of luck for new trademark application after considering prior prosecution history.
