A Seattle artist’s plea for fairness has come home to roost.

US District Judge Robert Lasnik refused to dismiss a lawsuit by Juli Adams, who says she was cheated out of millions when Hartz Mountain, which sold the line of plush Angry Birds toys she designed, licensed Finnish company Rovio — maker of the Angry Birds video game — to use her intellectual property without telling her.

Hartz maintains that it owns the Angry Birds trademark.
