Its all spelled out in EC261/2004.
If the LH ticket had been correctly updated/reissued, the OP would never had faced problems that occurred at FRA. My bet is that the OP never had valid ticket for the UA47 flight until someone resolved this at FRA - but then it was too late (all J/C class seats gone on UA47)
