Which patents do Facebook and Google use? Those companies are based on network effects and custom algorithms (not patented). I'll give you that Intel and AMD are coasting on their x86 patents. I'd add Qualcomm as well. Not sure about Apple and Microsoft. They are more based on copyright (ie. source code) although I may be wrong.

In any case this is a far cry from a "U.S. global monopoly on high tech products."
