Craigslists owns the unique compilation of their listings. That's what is at stake here.



And there's no copyright infringement as long as your compilation, based on their publicly available data, is also unique, which PadMapper's is. This has lots of precedents dating back to services derived from phonebooks.


I am interested in this. Can you point me to one or more of these precedents? Thanks in advance.



Is it?

In my interpretation it is the content of the listings, not the compilation. He could compile the data from several different sources and present the same result.


What constitutes a "unique compilation" is subject to interpretation in a court of law.

Adding/removing/modifying and changing the arrangement or display of items in a dataset sufficiently constitutes a dataset unique from the one Craigslist offers even if it is largely derivative from the Craigslist dataset.

Craigslist could argue a trespass to chattels tort or file a ToS civil suit, but there isn't much they can do to protect a dataset.

The reason Facebook makes Facebook content largely available only to those who are logged in is to hide behind their ToS and prevent scraping whether centralized or distributed.


As far as I know, in the US they don't.
