I'll back up my claim with a little bit of data...
"Beyond R&D spending, a crucial input into producing patents is education. Contrary to the stereotype of the college-dropout entrepreneur, innovation—at least as measured by high-quality patent activity—is almost exclusively accomplished by people with advanced degrees. Most often, this entails some amount of education beyond an undergraduate degree: 45 percent of triadic patent holders hold a PhD, MD, or equivalent degree, and 70 percent have at least a master’s degree. Only 23 percent completed only a bachelor’s degree, and 7 percent have not completed a four-year degree.
"Patent holders are substantially more educated than the rest of the population. Only 3 percent of the adult U.S. population has a professional or doctoral degree, but 45 percent of patent holders hold a degree at that level. And, while more than 90 percent of patent holders have at least a bachelor’s degree, just 27 percent of the overall population does. The importance of education in innovative activity highlights some of the broader spillovers to the economy from an educated workforce." [1]
