Sharp, which assembles Apple products among its other activities, was acquired by Taiwan’s Hon Hai Precision Industry – more widely known as Foxconn – in 2016 for US$3.8bn at a time when it was struggling with mounting losses. 

Local reports also suggested Sharp had been actively filing patent infringement cases in recent months including against US TV brand Vizio and Chinese smartphone maker OPPO.
