There are different levels of objection to a new gTLD
The deadline for formal objections expired on 13th March 2013. The objections are being published under this Link on the ICANN web site.
For “post-delegation” objections ICANN and the trademark community have developed the “Uniform Rapid Suspension System” (URS) which is a shorter and leyy expensive version of the UDRP. One of the first URS providers is NAF. ICANN is looking to expand the list of URS providers. UDRP remains a way of enforcing rights for any new gTLD.
