Re: Dear Apple.
"With trademarks, companies have to defend them, as that is the law." yes defend them when there is confusion. If cant teal the difference between a pear and apple logo you are fucked. This is a map company and does not compete in the same market. Following your logic if I had a plumbing supply store called Apple, Apple would have to sue me or lose the rights that is not the case. if that was so then you would see apple sue applebee's which has an apple logo.
Now if I were to start a computer company called apple V anda apple logo similar to apple computers I would expect to get sued.
