BMW sold Rover facilities, know-how, the MG brand & the Austin brand to Phoenix Group in 2000, but retained the rights to Rover, Land Rover, Mini, Triumph, Riley brand names.
The Rover brand was licensed royalty-free to Phoenix. But Phoenix soon rebadged Rover cars to MG.
In June 2000 BMW sold Land Rover to Ford (facilities, brand, know-how). The contract includes the article about Ford getting first refusal right for the Rover brand rights when BMW decide to sell it.
Nanjing Automobile then buys Rover facilities, know-how etc from Phoenix in 2005.
Now two Chinese companies (Shanghai Automotive & Nanjing Automobile) are interested in buying rights to Rover brand. BMW are willing to sell the rights. The negotiation about price are still on - but there are some rumours the Shanghai Automotive won the bidding race.
When the price is set, Ford will be asked to buy the brand at the price BMW & Chinese buyer have agreed. If Ford decline to buy the brand, then Chinese will get it.
After that BMW will still own the right to MINI, Triumph, and Riley brands.
