On Friday, Monsieur Louboutin's lawyer Harley Lewin filed an appeal to oppose YSL's move for summary judgment.
As of last week YSL said they were in the process of making the request for summary judgment because Judge Victor Marrero doesn't think Louboutin can prove why he needs a trademark on his shoes.
If granted, Louboutin's trademark could be canceled, which is why Lewin says his client plans to "fight like hell".
A hearing is scheduled for August 19th, so stay tuned.
