Johnson & Johnson are suing the Red Cross. Yep. I don't think I need to say much more, but I should probably give some context. Apparently whilst the red cross was given international rights to 'the red cross' back in 1864, the american branch of the red cross didn't open until after johnson & johnson had trademarked the symbol in 1887. Those kind hearted people at J & J put up with it til now, but have now changed their minds (cos the red cross sell some stuff for profit which is then syphoned directly back to their charitable work). So not only are they suing them to get them to stop using it, they're demanding back all profits made to date by the red cross and all their lawyers fees paid. This is the company with a yearly net income of 11 billion US dollars.
Personally I'm now boycotting their products which, unfortunately, are many. Course some people may agree that they've got a right to protect their brand, and I'm not suggesting anyone else do likewise. But in my opinion, if you choose to trademark a symbol which is already being used by a major international humanitarian organisation, you're a) an idiot or b) asking for trouble.
