I don't know. Does anyone know if HP managed to patent it before they published it?

It looks like it: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=1&f=G&l=50&d=PTXT&p=1&p=1&S1=7203789.PN.&OS=pn/7203789&RS=PN/7203789 http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sec..., http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=1&f=G&l=50&d=PTXT&p=1&p=1&S1=7359888.PN.&OS=pn/7359888&RS=PN/7359888 http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sec..., And another company has a related patent based on the usage of a memristor: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=1&p=1&f=G&l=50&d=PTXT&S1=memristor&OS=memristor&RS=memristor http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sec...

  Actually those seem to be related to a very different device which was in development in the same group -- an array of nanowires with single molecules at the intersections forming logical elements. Very cool, but very hard to fabricate, and not a memristor. Updated: Actually only the second one has molecules at the intersections, the other two seem to be more general.

    Eh, I must have been confused by the "pictures" posted of the memristor, because the patents describe the image that was getting shown in the articles. I'm not an EE by any stretch of the imagination, so I'd be inclined to take your word over mine. Edit I think this might be the correct one: http://www.google.com/patents?id=mWcGAAAAEBAJ http://www.google.com/patents?id=mWcGAAAAEBAJ

      Now I come to look at the image, you're right in that the new memristor architecture seems to a similar crossbar-style geometry similar to some of their previous inventions. It's possible that the first or the third one you posted might be general enough to encompass the memristor system as implemented, but I don't think either of them is specifically related to the new let's-diffuse-ions-across-a-thin-semiconductor-film memristor idea.
