I think you missed the point. It's a Mac app to downsize images. The trademark is for 'Electronic hand-held game units other than those adapted for use with an external display screen or monitor;'.

Also Apple were happy with the name for the first 6 weeks of the Mac App Store being open.

It is possible to have more than one trademark for a given word, and Apple has (at least) two for "retina":

The one not mentioned in the article is for "Computers; computer hardware; computer displays; computer software; handheld mobile digital electronic devices used as a telephone, handheld computer, personal digital assistant, electronic organizer, and electronic notepad, and used to access the Internet, electronic mail, and other digital data".

I got that. As has also been mentioned, the trademark is for other things as well.

Essentially, Apple's Retina display is a specific trademark. Unretina isn't billed as an app to downsize images. Rather, it's an app that downsizes Retina® images.

Essentially, their marketing is piggybacking on Apple's trademark.

That's an awful assumption based on no evidence. That it was on the App Store only means that they hadn't yet decided to take action, or that those responsible for taking action hadn't decided they should.
