After trying this once before with Samsung and the BlackJack moniker, BlackBerry maker Research In Motion is suing LG over product names.

RIM states that the names of some of LG's recent models including Black Label, Strawberry and Black Cherry are too BlackBerry-esque.

In a complaint filed in the US District Court for the Central District of California, RIM thinks any wireless devices with "Black, Berry or Pearl" in the name are a little too close for comfort.

As well as the existing products, LG has filed additional applications for the Chocolate Black Label Series, Black Jewel, Black Jewelry, Blackruby, Blackpearl, and Pearlring names too.

"RIM's BlackBerry wireless handheld devices and the goodwill associated with its BlackBerry marks are invaluable to RIM's continued success", RIM's filing said.

"The aforesaid actions of LG have caused, and, unless enjoined, will continue to cause monetary damage and irreparable injury to RIM and the BlackBerry marks for which there is no adequate remedy at law."
