<p>We define hits as patents with top 10% impact. Horizontal axis is number of patents including a hit and all subsequent patents by the same team that made the hit. The hit is not necessarily the team’s first patent. Vertical axis is average impact. Horizontal axis is cut so that number of samples is greater than approximately 100. Red, grayish red, blue, and grayish blue lines correspond to Japanese “no switch,” Japanese “switch to new team,” U.S.’s “no switch,” and U.S.’s “switch to new team.” Brackets show standard errors. Black horizontal line is impact = 1.</p
