Fleming threatened to rename the character 'Goldprick', and the case never came to court.

[Brutalism's] most notorious exponent was the patrician Hungarian-born architect Erno Goldfinger, who lived in an uncompromising concrete framed cottage in Hampstead that he had designed himself, infuriating his wealthy neighbours. The novelist Ian Fleming took such exception to Goldfinger's home that he used his surname for one of James Bond's most evil adversaries. When Goldfinger consulted his lawyers, Fleming threatened to rename the character 'Goldprick', and the case never came to court.
