"how many people can possibly work at an IP company?"
ever heard of Ballard Fuel cells? it's most likely where Ford and DaimlerChrysler will get all their fuel cells. until about 1998, they were ONLY an IP company, but their costs for R&D were huge! in the hundreds of millions. they only had about a hundred people, but MAN, thats alot of money. they needed it all, becuase they were experimenting with many many different materials to find the best combination for efficient, yet low cost Fuel cells.
well recently, they've frozen IP somewhat so that they can begin manufacturing their fuel cell which will be going into 2003 cars.
Ballard was competing against companies the likes of GM, with millions of dollars (american None the less) of profit, but the way ballard worked, because they were such a small company, the were able to manouver MUCH better then GM or other fuel cell research teams, and have turned into the world leaders in fuel cell tech (which is why daimlerchrysler, and ford bought into them!).
oh, and did I mention that Ballard is a Canadian company? go figure..
