Came here to say the same thing; I excitedly thought it was an announcement for a new Calibre beta.

Looks like Calibre also holds a trademark: http://tmsearch.uspto.gov/bin/showfield?f=doc&state=4806:h6j...

There seems to be a high likelihood of confusion given that both are software products, but IANAL.

IANAL but I don't think the trademark is an issue. Might make it a bit hard to search for, though, when "calibre app" is dominated by calibre e-book software.

I thought the same but was not excited, because Calibre is almost completely perfect already. If anybody reading this ever wants to convert ebooks from one format to another, or turn web pages into ebooks, or any such thing, definitely check it out.

I think the trademark issue should be OK.

My understanding is that you can have overlap in trademarked names when it's in very different markets, but IANAL

Knowing the court's record of incompetence when it comes to technology, I doubt they'd be able to distinguish the two beyond "software companies".
