They let it expire, and now they complain? (Score 5, Insightful)

The content in question was created in the last 40s/early 50s. As anyone following recent copyright law and the Eldrich case should realize, anything from that time had the potential to be copyrighted for a few more decades without incident. However the laws that existed during that period required that you could extend your copyright a given number of times. Fox did not file that paperwork.

The content fell into public domain, clear and simple. It's available for anyone to do anything with it that they please, and now they're crying foul.

I think the fact that they didn't file for copyright extension should get this thrown out instantly. These guys have huge amounts of copyrighted works they own, and they are constantly extending their legally available copyright for the rest of it. When they decide not to file, it's because they think the content is no longer exploitable, so they don't bother.

In this case they were proven wrong - Dastar was able to use it in an appropriate way, and now Fox, who had abandoned it, says it's theirs? Come on, make up your minds.

Here's the history of the movie - judge for yourself if you think they have the moral high ground here:

In 1948, three and a half years after the German surrender at Reims, General Dwight D. Eisenhower completed Crusade in Europe (Crusade), his written account of the allied campaign in Europe during World War II. Doubleday published Crusade and registered it with the Copyright Office in 1948. Pet. App. 9a. Doubleday granted the exclusive television rights in the book to an affiliate of respondent Twentieth Century Fox Film Corporation (Fox). In 1949, Fox made a television series based on Crusade, and registered the series with the Copyright Office. Id. at 8a-10a.1 In 1975, Doubleday renewed the copyright on the book as the "proprietor of copyright in a work made for hire." Id. at 9a. Fox, however, did not renew the copyright on the Crusade television series, Br. in Opp. 20-21 n.4, and that copyright expired in 1977.2
