 Hi there,  
Thank you for submitting your complaint. As a preliminary matter, please 
note that YouTube is not in a position to mediate trademark disputes 
between users and trademark owners. As a courtesy we have considered your 
claim, but do not find grounds to remove the content at issue. If you have 
continued concerns, we encourage you to resolve the dispute with the 
uploader. You may be able to contact the uploader through YouTube's 
private messaging feature. Instructions on how to use this feature can be 
found at the following link:
