In June 2016 NICHIA commenced a lawsuit claiming that certain white LED-containing products sold by B&Q plc, the largest DIY company in the UK, and sourced from third-party Asian manufacturers infringed Nichia's European “YAG” patents.

After Shuji Nakamura was awarded the 2014 Nobel Prize in Physics last Tuesday, the lawsuit the Japanese scientist brought against former employer Nichia in 2001 over patent compensation received renewed media attention. The Japanese LED manufacturer insisted it compensated Nakamura fairly for his work at a press conference in Taipei on Thursday.
