As a result, Q CELLS would be petitioning for the invalidity of REC’s alleged patent in China. The SMSL member also noted that it was considering other “legal avenues”. 

Q CELLS has previously sued REC Group, JinkoSolar and LONGi Solar over PERC (Passivated Emitter Rear Cell) processes with numerous cases pending and petitions of invalidity ongoing.
