Australian supermarket Woolworths changed its logo last year. While it's technically the letter 'w' Apple seems to think the fact that Woolworths made its new look like a peeling apple warrants legal action.
According to AppleInsider, Woolworths has applied for a blanket trademark for the logo and while the green 'w' does seem more food orientated, the company's application also extend electrical goods and technology. "While we can't rule [computers, musical players, or other devices] out, we haven't got any plans at the moment," said a Woolworths spokesman, according to AI.
Apple is making its case to IP Australia. WSJ reports that under IP Australia rules, a company can challenge the validity of another company's logo if it can successfully argue that it may cause confusion in the minds of customers.
