Big telephone companies are filled with lawyers but have few engineers/scientists these days.
Apple/Google will be the same someday.
I think some do have a "few" or then they have way too large wages.
R&D spendings:
Top 10 worldwide:
3. Microsoft 6,07Mrd€
7. Nokia 5,00Mrd€
10 Samsung 4.51Mrd€
(btw, 1 Mrd = 1 american billion...)
It looks like those companies like to sue other companies... Some of those patents and for what they can be used is pure madness...
