Apple was awarded a Registered Trademark for WebKit on March 7th
I was reading /. earlier today and nested in the comments was a post by someone who brought up that Apple filed for a trademark in the US on March 5th and was granted 2 days later for WebKit. Surprisingly no one on slashdot really commented on the find.
This makes sense why Google wants to differentiate its self with it's own browser engine.
Something of an interesting observation, I thought I would share with everyone.
