This type of licensing tends to pose an issue for the retention and preservation of video games particular on digital download services. Publisher can sometimes secure perpetual rights to a licensed property, such as in the case of Ubisoft with the name Tom Clancy.[58] Otherwise, with limited-time licenses, publishers are generally required to remove the game from sale at the end of that term, though existing owners of the game often still have rights to redownload and use the game as necessary.
