Lets consider past patent deals.
# of patents: 882
cost of patents: $450,000,000
450,000,000 ÷ 882 = $510,204.08 per patent
# of patents: 24,500 (17k patents, 7k pending)
cost of patents: $12,500,000,000
12,500,000,000 ÷ 24,500 = $510,204.08 per patent
# of patents: 6,000
cost of patents: $4,500,000,000
4,500,000,000 ÷ 6,000 = $750,000
Also bear in mind that Google gets sole ownership of Motorola patents, whereas the Nortel deal was done through a consortium of Apple, Microsoft, RIM, and others.
Add to that Google now just gained access to millions of peoples' homes by acquiring Motorola's existing Set Top Box business.
Did this shake the tech industry to the core? HECK YES
I'll bet you money that Apple will be acquiring a company for its patents or even more soon.
