Apart from the exact match of your trademark, the Trademark Clearinghouse also recognizes abused names like deliberate typos and misspellings. Suppose your company name is Example and in the past somebody abused your name by registering Exaample in a certain extension. If there has been a UDRP decision in the trademark holder's favor for that domain, you might be eligible to include that misspelling in your TMCH order. Up to 50 of such additional labels might be added and additional costs apply.
Those additional labels can not be registered during the Sunrise phases, but will receive any trademark claims notification if somebody else tries to register that name.
Please contact our Sales department if you have any trademark including abused variants.
