About the parties: 
Osram Sylvania is the North American operation of lighting manufacturer Osram, which is owned by Siemens. It was established in January 1993, with the acquisition of GTE’s Sylvania lighting division by Osram GmbH. The company produces a wide range of lighting products for home, business and automotive use. It sells its North American products under the Sylvania brand name and uses the brand Osram in the rest of the world. 

Artison primarily operates in the audio and video equipment manufacturing company. It specializes in flat panel display.

As in complaint:
Plaintiff alleges that the defendants have infringed the above patents through sale of its MusicLites (see Fig. 1), a combination light-speaker product. MusicLites are wireless-enabled speakers that combine a full-range speaker with an LED light. MusicLites are used with several different wireless transmitters to work with various audio sources.  Artison provided the audio technology for the Musiclites. Both the defendants have marketed them to wholesalers as well as retailers as indicated on their website www.musiclites.com
