Designed by the famous French fashion designer, Isabel Marant, the Étoile Satchel bag is also patented.
The Étoile Satchel bag was awarded the US design patent USD630434 (S) titled Handbag.
As a reminder a US design patent is different from a US utility patent, in that:
A “utility patent” protects the way an article is used and works (35 U.S.C. 101), while a "design patent" protects the way an article looks (35 U.S.C. 171)” (USPTO)
