Here's another make: tri-spoke wheels (material unknown, but I'd guess carbon) and these are curved spokes. So far all the ones I've seen are straight, so these are from another company.
(I do not know who makes the wheels, but it's a start anyway)

There was a recall on the Porsche MTBs but what I found only mentioned the carbon handlebars and seatposts, I didn't see anything bad about the wheels.
