Top AMERICAN Patent Holders

 

 

 

 

 

 

 

In 2006, the Patent Office reported that 46% of the top 25 patent holders of AMERICAN patents were Japanese, 9% were Koreans, 5% were Germans, 2 1/2% were Dutch, and only 46% were Americans.  This compares to Americans being 60% of the the top patent holders between 1973 to 1996, and 30% in 1996.

The problem, though, is that the vast majority of the top scientists and engineers in "American" companies are Asians, most of whom aren't even American citizens, and many who weren't even educated here.  Many of those who were educated here at our expense now go back to their homelands where, after personal taxes are considered, their take-home pay is higher than here.
