If IBM didn't think that it would be awarded patents for work like this, why would they bother to do the research in the first place?
Surely you don't think the only reason people do research and advance science is due to hope of compensation?
How do they get the carbon nanotube in the correct position and orientation like that? I suspect it will be difficult to do it reliably and cheaply for billions of transistors at a time.
The answer can be found in the supplementary information to the article here: http://pubs.acs.org/doi/suppl/10.1021/nl203701g/suppl_file/n...
In short, they grew the nanotubes on a quarts crystal, transferred them with tape quite randomly to gates already made on a Si-wafer and then etched and metalized around these gates. They then tested a large amount of devices to find ones where a nanotube of the right kind (semiconducting) had placed itself in a correct alignment with the gate and metalized contacts (source and drain). Once they knew what devices were working they imaged some of the working devices with an Atomic Force Microscope (AFM) and did a bunch of standard transistor measurements.
As was commented earlier, the specific growth of nanotubes in a well defined position is not easily achieved. There is IMO a long time until anyone can do a full chip where nanotubes grow exactly where one wants the transistors. It might even be that graphene is a more convenient technology for just this reason (since graphene can be grown somewhat more conveniently by annealing SiC wafers). A side note I guess is that growing nanotubes and pillars vertically can be done in specific spots on a wafer, but that makes manufacturing of the gate a bit problematic. And I do not know wheter carbon nanotubes can be grown selectively this way.

That might not be the only reason for people , for companies however it would be silly to spend money without hoping to get it back somehow.
As I said, this is a dream (and a pretty silly one at that). I can still hope though

You don't need patents to create and execute big ideas. As a company or anything else. As I said, this is a dream (and a pretty silly one at that). I can still hope though

The alternative to patents is secrecy. I think the patent system was originally introduced because it was deemed superior to make ideas public, but limit their commercial usability.
When I think of IBM, I still think of consultants and guys in blue suits. ...but more than anyone else out there, these guys are building the future.

I hate to think what their patent portfolio looks like.
It's true that IBM does incredible research, but their results never seem to break into mainstream.

Your horrible spelling aside, I wouldn't mind seeing the patent system suffer an irreversible data corruption, along with a fire destroying all hard copies. A forced reset, as it were.

Its patent portfolio is huge -- the biggest in the world. They have registered the most patents per year for, like, the last 10 years. More than 5,000 per year! (Next biggest is Samsung and MS, which have averaged around 2k-3k per year, I think).
