Seoul: LG Electronics said on Wednesday it had signed a long-term cross-licence deal with Google as the South Korean firm tries to expand its smartphone business.

The deal covers patents on a “broad range of products and technologies” that already exist and will be filed in the next 10 years, the two firms said in a joint statement.

Samsung — LG’s home rival and the world’s top smartphone maker — earlier struck a similar deal with Google in January. Almost all of LG’s popular smartphones, tablet computers and smartwatches are powered by Android software made by the US tech giant.

LG — currently the world’s fourth-largest smartphone maker — struggled for years with sluggish sales after making a late entry into the market.
