Retail vs Interface ⚓

Peter Bright for arstechnica.com:

LCA's memo reportedly says that Microsoft has been threatened with legal action for infringing on "Metro" trademarks held by German retailer Metro AG.

This is a very sad day for me. A brand name of a big German Retailer cannot be used in a totally different context, namely the new Interface of Windows 8. There is something really wrong with the Trademarks and Patents system.
