Right or wrong, 'Palantir' is a great name for this kind of company.
Wouldn't the Tolkien Estate have a copyright on that?
Could I start a newspaper tomorrow called "The Daily Bugle"...(which is where Spiderman works)?

Even if it does, and I'd love to see more details about that (Google translates 'openly' as 'palam'), it's clearly a LotR reference.
Palantir.com doesn't seem to have anything referencing the source of the name.
