Perhaps feeling the heat of the Internet, King is now filing for express abandonment of its trademark on the word "Candy."

The Candy Crush Saga developer confirmed the move to Kotaku.
King has withdrawn its trademark application for Candy in the U.S., which we applied for in February 2013 before we acquired the early rights to Candy Crusher. Each market that King operates in is different with regard to IP. We feel that having the rights to Candy Crusher is the best option for protecting Candy Crush in the U.S. market. This does not affect our E.U. trademark for Candy and we continue to take all appropriate steps to protect our IP.

I'm sure this has nothing to do with King filing an IPO with the New York Stock Exchange and wanting to not look like a bunch of bad guys.
