Delaware State court has ruled in favor of semiconductor assembly and testing company Amkor Technology in its patent suit for semiconductor assembly test services. The court found that the patent transfer and license agreement to Amkor were both valid and Motorola was not entitled to any royalty payment.
The dispute stemmed from a 1996 patent license agreement between Motorola and Citizen Watch that allowed citizen the right to use the patents covering the semiconductor test services, also known as ball grid array (BGA) packages.
Amkor also had a patent license agreement with Motorola for which it paid a quarterly royalty. Citizen’s deal also included an assignment of un-divided one-half interest in two of Motorola’s patents. Amkor acquired Citizen’s BGA units in March 2002 and got Citizen’s one-half interest on the two patents and the right to use the patent license. Motorola, however, claims that Citizen had no right to transfer the patents and Amkor was entitled to pay the company.
Court found that the assignment was effective and Amkor successfully acquired Citizen’s rights in the license and patents.
In August 2007, Motorola filed a suit against wireless LAN company Aruba Networks alleging infringement against use of Motorola’s proprietary WLAN switches technology and technique for designing and managing WLANs.
