LG has set the legal attack dogs on Sony, over Blu-ray playback tech used in the PS3, Bravia TVs and some Sony VAIO laptops and some cameras and camcorders.
Where better to do this than the US, where Korean vendor is seeking to stop sales of Sony products that allegedly infringe four LG patents.
LG filed the complaint with the US International Trade Commission in response to a suit filed by Sony with the organisation in December 2010, seeking an import ban of LG smartphones, according to Florian Mueller, the German free software activist.
"It's like 'you touch my smartphones and I bomb your console'," he wrote on the FOSS Patents blog.
