The US non-profit organisation Gluten Intolerance Group (GIG) has initiated a lawsuit against the world well-known chef Jamie Oliver.
GIG possesses a certification trademark GF which certifies that the relevant food products are gluten free. It is required the products to pass strict certification program.
In the case at hand, GIG claims that Jamie Oliver has used the sign GF for some of his recipes without to prove that the products have passed any certification process.
According to the organisation, this constitutes a trademark infringement which can create a confusion among the consumers that the products have been previously certified so as to use the sign GF.
