This is Shocking; GUCCI LOSES TRADEMARK INFRINGEMENT CASE AGAINST GUESS IN FRANCE

I think they look very similar but apparently not in France.  Gucci has been accusing Guess of trademark violations for years, but this past Friday in France this case was put to rest; court ruled in Guess's favor.  Gucci's request of $62 million was denied and they were actually ordered to pay Guess about $34,000 instead.
Finding: 

• no trademark infringement
• no counterfeiting 
• and no unfair competition between the luxury Italian label and American mall brand
• The court also nullified Gucci's trademark of three of its "G" logo

Reps from Gucci strongly disagree with this decision and would be appealing.
