I have previously reported about the Michael Jackson Asian Rights Co. (MJAR), a company set up by an "almost business partner" of MJ. The company similarly to Vintage Pop Media LLC claims that they have the rights to use MJ's likeness to sell merchandises. On their website they list some of the trademarks they think they own: "Michael Jackson", "Michael J. Jackson", "Michael Joseph Jackson", "MJ", "MJJ". They even created a logo claiming they got the rights from MJ himself (http://mjfc.jp/information/mj%E3%83%AD%E3%82%B4s.jpg)
MJAR recently updated their websites with two new mobile developments. As well they sent out a press release about a new Thriller doll (http://www.goodsmile.info/product/en/3037/figma+Michael+Jackson.html)
Contrary to what MJAR claims, according to the Japanese Trademark Office the only MJ trademark registered so far is owned by the MJ Estate (some recently registered claims haven't been accepted yet).
As a tidbit: Melissa Johnson's trademark claims have been rejected in Australia, UK and Germany recently.
