• Are Fictional Characters Protected Under Copyright Law? (Kathryn Goldman on Jane Friedman's blog, 7-14-21) Goldman, an intellectual property lawyer, writes: "Jack Ryan, the analytical, yet charming CIA analyst, made an appearance in federal court in Maryland earlier this year. The heirs to Tom Clancy’s literary legacy are fighting over him. Unlike in the movies, he’s not in a great position to fight back....
"Here’s the crux of the current court battle: When Clancy mistakenly transferred his copyright in the book Red October to the original publisher, did the copyright to the character Jack Ryan go with it?
