Behind Lenin's Tomb in Moscow there is a small door embedded in the Kremlin Wall where Soviet rulers used to duck through on their way to presiding over the annual May Day Parade.
The door is small and, according to a Russian soldier I met there a decade ago, it was deliberately so because of Stalin's diminutive stature.
After all, if he was about to acknowledge the size of his huge army, the last thing he needed was to be reminded of was his lack of height.
Rather like Stalin's door, the, er, window of opportunity for Russian entrepreneurs has been similarly narrow. Inventors and creators were employed by the State and any resulting IP or patents would be owned by the State.
