> Gras and Golestanti have patented the software,

yuck

imagine if the fast fourier transform had been "patented"

imagine if the "mean" (sum of all values divided by the number of values) had been patented

do they even give the full algorithm in the paper? if not how was the paper published?

OK went to the actual paper: http://goo.gl/hkiQKp

How can they patent the algorithm when the work was funded by the government (i.e. the public)? Even if it's legal, it's not ethical.

You can now get Ti ADCs that can be used for capturing EEG data from electrodes for around $30 iirc, so surely it'd be possible to make one cheaply enough?

I'd agree, and the portable ones don't give access to raw data so you have to hack them. I wonder if a robust headset will come to market soon?
