Los Angeles, California: DDD Group plc (AIM: DDD; OTCQX: DDDGY), the advanced imaging and 3D solutions company, confirms that it’s Australian subsidiary, Dynamic Digital Depth Research Pty Ltd (“DDD”), has filed a lawsuit in Los Angeles alleging that LG Electronics’ (“LG”) range of 3D televisions infringe three of DDD’s U.S. patents.

 The complaint alleges that the automatic 2D to 3D conversion function performed by LG’s range of 3D televisions infringes the claims of DDD’s U.S. Patent No. 6,477,267 “Image Conversion and Encoding Techniques”, U.S. Patent No. 6,496,598 “Image Processing Method and Apparatus”, and U.S. Patent No. 7,489,812 “Conversion and Encoding Techniques”.

 The complaint notes that despite the fact that LG licensed DDD’s TriDef 3D solutions for use with their 3D personal computer products and their 3D mobile phones, the engineering team responsible for the development of LG’s 3D televisions pursued the development of their 3D TVs in full knowledge of the existence of DDD’s patents and technologies. As a result, the complaint alleges that the LG has demonstrated a pattern of blatantly disregarding DDD’s intellectual property and by doing so, LG is getting a “free ride” on DDD’s decades of research and development, and unfairly competing in the marketplace since first announcing their range of 3D TVs in late 2009.

 The complaint seeks injunctive relief and unspecified monetary damages and contends that since LG’s infringement has been, and continues to be, willful, DDD is entitled to seek treble damages and an award of its attorneys’ fees, costs, and expenses.

 DDD also announces that it has retained Quinn Emanuel Urquhart & Sullivan, LLP (“Quinn Emanuel”) to work alongside Dominion Harbor Group to protect DDD’s intellectual property rights and enforce its patent portfolio. The Quinn Emanuel team engaged by DDD who are working on the complaint against LG includes partners William Price (Washington, DC), Alan Whitehurst (Washington, DC), Amar Thakur (Los Angeles), and Marissa Ducca (Washington, DC).

 Chris Yewdall, Chief Executive of DDD, said: 

“DDD has invested heavily in its intellectual property portfolio over the years and we have licensed the DDD technology to many companies on fair and reasonable terms. Unfortunately, some companies have refused to license the proprietary DDD technology that they are using. We are pleased to have an experienced team of top litigators helping to enforce DDD’s IP rights with respect to LG and to generate additional returns on DDD’s IP investments.”

 Alan Whitehurst, Partner at Quinn Emanuel Urquhart & Sullivan LLP, said:

“Our clients are of the highest caliber, and we are proud to count DDD among them. With the help of Dominion Harbor, we plan to leverage our trial-proven IP experience and depth of resources in order to maximize the value of DDD’s IP.”

 David Pridham, Chief Executive of Dominion Harbor Group said:

“Quinn Emanuel’s reputation as a world-class patent litigation firm and the enthusiasm they have shown for the opportunity to work with DDD made their selection an easy choice. They have an exemplary track record as one of the go-to firms for ‘bet the company’ intellectual property litigation for the world’s leading technology businesses.”
