Last week,Twitter filed a complaint with the WIPO Arbitration and Mediation Center,asserting legal rights over Twiter.com .Now,the company has added an additional domain name to its dispute .
Twitter decided to go after Twiter.biz also .Twitter was allowed to add another domain name to its dispute ,as long as the registrant is the same .
Twiter.biz domain name doesn't resolve to a website .
The case is still pending compliance checks with WIPO Arbitration and Mediation Center .
