Another approach some companies have used to prevent clones is via trademarks as to prevent clones and knockoffs. Notably, King have gotten a United States trademark on the word "Candy" in the area of video games to protect clones and player confusion for their game "Candy Crush Saga". They have also sought to block the use of the word "Saga" in the trademark filing of "The Banner Saga" for similar reasons, despite the games having no common elements. Within the European Union, one can register for a European Union trade mark that includes multimedia elements, which would allow a developer or publisher to trademark a specific gameplay element that is novel from past games, providing a different route for them to protect their work from cloning. For example, Rebellion Developments filed to register its "Kill Cam" mechanic as a trademark from its series "Sniper Elite" in October 2017, though as of February 2018, the application is still being reviewed.
