Created works (books, media, etc) are fair game and will be free for all to use and build upon, without permission or fee 95 years after its creation. Per current US Copyright law. That means in 2072 or thereabouts anyone can make a Star Wars movie, novel, action figure without recrimination (even if LFL is still around).

They enter the public domain on January 1 after the conclusion of the 95th year. Works published from 1923-1977 had to meet certain requirements to be eligible for the 95-year term—they all had to be published with a copyright notice, and works from 1923–1963 also had to have their copyrights renewed after the initial 28-year term. Foreign works from 1924 are still copyrighted in the US until 2020 if 1) they complied with US notice and renewal formalities, 2) they were published in the US within 30 days of publication abroad, or 3) if neither of these are true, they were still copyrighted in their home country as of 1/1/96. Note that the copyright term for older works is different in other countries: in the EU, works from authors who died in 1949 will go into the public domain in 2020 after a life plus 70 year term, and in Canada, works of authors who died in 1969 will enter the public domain after a life plus 50 year term.
