LG sues TCL in Germany for patent infringement

Three LTE patents are at the centre of multiple patent infringement lawsuits filed by LG against TCL.

LG Electronics (LG) has filed multiple lawsuits in the German district courts of Mannheim and Düsseldorf against TCL, a Chinese handset manufacturer, for infringing its LTE technology patents.

The lawsuits allege that TCL knowingly implemented technologies in its handsets that infringe three of LG’s patents that cover key areas of LTE handsets: minimizing the loss of packet transmission, control timers for uplink synchronization and interference reduction in the uplink synchronizing process.

According to LG, numerous attempts were made to remedy its concerns with TCL before the suits were filed, to no avail.

LG has successfully asserted its extensive LTE patent portfolio on a number of occasions in the courts by legally challenging the unlawful use of its technologies.

As a result of recent legal action, Miami-based BLU agreed to a licensing deal with LG and a German trial court ruled in favor of LG in three separate litigations against Wiko, a French subsidiary set up by Chinese original design manufacturer Tinno Mobile .

LG is filing these lawsuits to protect their investments, challenge the unlawful use of their vital assets and to safeguard the competitiveness of the industry for future innovation.

“LG has long invested heavily in LTE innovation and when it becomes necessary, we take action to protect these important assets,” said Jeon Saeng-gyu, executive vice president of LG’s Intellectual Property Center. “As a leader in LTE technology, we have a responsibility to ensure that competition in the industry takes place fairly and legally”.
