“The lawsuits allege that TCL knowingly implemented technologies in its handsets that infringe three of LG’s standard essential 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.

“The suits against TCL were filed only after numerous attempts were made by LG to remedy its concerns, 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.”

TCL also manufactures smart TVs.

Lawsuits like this are not uncommon in the tech world, but this is a notable one given LG’s longevity in the mobile game and TCL’s relatively short time in it. It’s an old hat accusing a newer competitor of intellectual property theft.

It also serves as reminder that not all companies share their network technology. LG believes rather than license its patented LTE tech from them TCL has illegally copied it. We wait to see what the ruling is.
