Quite right. One of the first attempts to make a Bond film in the 1950s resulted in a script, not written by Ian Fleming, that Fleming subsequently turned into the novel Thunderball. There was a legal battle that ran for over 40 years over various rights in the script, the characters, the book and the films. Kevin McClory, the producer of that first failed film, retained the rights to Blofeld and SPECTRE. McClory died last week, so watch this space.
The rights to SMERSH are probably still with the Russian FSB, given recent events in Piccadilly sushi bars.
