What he did was he looked at those companies that had an R&amp;amp;D center in USA and in India, and then he looked at a patent that was filed out of the U.S. and a similar patent filed out of the same company's subsidiary in India, so he's now comparing the patents of R&amp;amp;D centers in the U.S. with R&amp;amp;D centers in India of the same company to find out what is the quality of the patents filed out of the Indian centers and how do they compare with the quality of the patents filed out of the U.S. centers?
