Some numbers in news:
- Microsoft paid AOL $1B+ for <900 patents for an average price of $1.3M. I dont know the max, min and median value of a patent in this portfolio. I have been skeptical in the past with researchers' explaining their super algorithms to me how to ``value'' a portfolio of items including patents, I wonder if any of them would have estimated this value.
- A few months ago, Mitt Romney released details of his tax returns. One number is on taxable income of $21.7M, he paid $3M in taxes. While media has focused on the effective tax rate of 13.8%, but some of the others focus on a different rate. It is estimated that his net assets are like $200M, but some fraction (<1/2) of it generates taxable income. How does he make 20%+ return a year on his assets?
