The Tokyo District Court issued a verdict in favor of Sharp Corp in the lawsuit where the company sought a court order to ban imports and sales of an LCD TV and two LCD monitors that use a certain LCD module of Samsung Electronics Co Ltd.

Sharp filed the lawsuit (Tokyo District Court 2008 (wa) No.14530) against Samsung May 30, 2008. Sharp claimed that the LCD module included in the Samsung Electronics' 40-inch LCD TV and the 19- and 30-inch LCD monitors infringe on three of Sharp's patents (No. 3872798, 3901721 and 3744714) related to technologies to realize wide viewing angles, enhance response speeds, etc.

The court ruled that Samsung infringed on patent No. 3872798. Sharp is now considering filing another lawsuit to ban other products that use the same LCD module.

On the other hand, on Jan 26, 2009, the US International Trade Commission (ITC) supported Samsung's claim that Sharp infringed on two of Samsung's patents. The ITC issued a tentative ruling that orders Sharp to stop importing and selling its LCD-related components for LCD TVs, notebook PCs and mobile phones as well as such end products in the US. Six ITC members will start investigating the tentative ruling from now.

Sharp also filed a patent infringement lawsuit against Samsung with the ITC, and the case will be investigated in the near future. The two companies are engaged in patent infringement trials in the US, Korea, Germany and the Netherlands.
