Fruity purveyor of broken iPhones, Apple has trademarked its ubiquitous catchphrase "there's an app for that".
Apparently Apple filed for the trademark back in December 2009, claiming that it brought the phrase to the attention of the world+dog on January 26, 2009.
The trademark was filed in the Advertising, Business and Retail Services, Computer and Software Services and Scientific Services categories. So it means that you can use it in any field outside those regions. So if your penguin breaks down "there is an App for that" is a perfectly legal phrase you can use.
The trademark applies to "retail store services featuring computer software provided via the Internet and other computer and electronic communication networks; retail store services featuring computer software for use on handheld mobile digital electronic devices and other consumer electronics."
So if you are not selling something and you use the phrase, perhaps when you are tossing and turning in your sleep, you do not have to worry about a knock on the door from Apple lawyers.
Apparently the phrase "there is an app for that" has become so popular that it has permeated pop culture and become repurposed and parodied. It is for this reason, Steve Jobs wants to control it.
However, we can safely say that the phrase "there is an app for that" has not appeared in our conversation, or the conversations of any of our friends. It is the sort of thing that a bloke who in a perfectly ordinary conversation about badger sex would say "there's an app for that" and burst into laughter which only he would share. Normal people do not hang out with such types.
