A judge ruled on Wednesday that the singer-songwriter had not plagiarised the 2015 song 'Oh Why' by Sami Chokri.
Chokri, a grime artist who performs under the name Sami Switch, had claimed the "Oh I" hook in Sheeran's track was "strikingly similar" to an "Oh why" refrain in his own track.
After the ruling, Sheeran said such "baseless" claims "are way too common".
In a video on social media, he said there was now a culture "where a claim is made with the idea that a settlement will be cheaper than taking it to court, even if there's no basis for the claim".
