H&R Block sues Jack Dorsey's Block, alleging copyright infringement

H&R Block wants to knock Jack Dorsey’s “Block” off over a copyright conflict.

The tax advice provider H&R Block is suing Block, Jack Dorsey’s financial tech company, accusing it of infringing on its copyright. The tax preparation company claims Block’s name and logo are nearly identical to its own, according to a lawsuit filed in the U.S. District Court for the Western District of Missouri on Thursday. The complaint seeks to stop Block from using the name and logo, as well as three times the damages or profits that Block may have made using the name.
