Perdue v. Random House Inc

Ain't happening says Judge Daniels. Dan Brown borrowed themes and facts from Lew's books to conceive the Da Vinci Code. A lot of them even with the same characters doing the same things in the same context on the same pages, but added just enough to escape infringing the previous work.

The question is what is protected and what isn't? As for "series," only Angels & Demons is related to DVC. There is no question Brown borrowd thematics heavily, as all are present in Lew's books. The problem is he draped them in just enough new material to apparently get by with it. At least legally.
