Marvel's Kevin Feige Says It's 'Wonderful' to Have X-Men, FF Rights Back; Comic Book Resources, April 16, 2019

Colin Hickson, Comic Book Resources; Marvel's Kevin Feige Says It's 'Wonderful' to Have X-Men, FF Rights Back

"Despite their prominence in Marvel Comics, many fans were disappointed that the X-Men and the Fantastic Four were not included in the Marvel Cinematic Universe since their film rights were owned by 20th Century Fox. However, with Disney's purchase of the rival studio, Marvel has regained access to the two franchises, and Marvel Studios President Kevin Feige couldn't be happier.

"The specifics of what it means remains to be seen, but overall it's wonderful and it feels like these characters have come home", Feige said in an interview with Variety. "It will be nice to have what every other [intellectual property] holder that I can think of has, which is access to all their IP.
Imagine if Donald Duck was at another studio. Imagine if Goofy or Moana were someplace else and you didn’t have access to them even though they are yours.""

Jack Kirby’s heirs take Marvel copyright fight to Supreme Court; ComicBookResources.com, 4/3/14

Kevin Melrose, ComicBookResources.com; Jack Kirby’s heirs take Marvel copyright fight to Supreme Court:

"Claiming an appeals court “unconstitutionally appropriated” Jack Kirby’s copyrights and gave them to Marvel, the late artist’s heirs have taken their fight with the comics publisher to the U.S. Supreme Court.

In a petition filed March 21, and first reported by Law 360, Kirby’s children argue “it is beyond dispute” that the artist’s Marvel work between 1959 and 1963 was not produced as “work for hire” and, therefore, is subject to a clause in the U.S. Copyright Act that permits authors and their heirs to reclaim copyrights transferred before 1978.

The appeal follows an August decision by the Second Circuit upholding a 2011 ruling that Kirby’s Marvel works were indeed made at the “instance and expense” — that term plays a significant role in the heirs’ petition — with the publisher assigning and approving projects and paying a page rate; in short, they were “work for hire.” As such, the courts found, the 45 copyright-termination notices the artist’s heirs filed in 2009 for such characters as the Avengers, the X-Men, the Fantastic Four and the Hulk were invalid."
