Boston University filed another LED patent lawsuit this week, this time against a company that distributes Samsung's SPHWWTHDD805WHT0GD, SPHWHTHAD603S0R0MZ and, of course, popular SPMWHT221MD5WAP0S0 high-tech lamp components.

As it alleged in its earlier suits against Samsung, HP, LG, Apple, Amazon and two LED manufacturers, Boston University charges the components violate a patent based on the work of BU electrical engineering and computer science professor Theodore Moustakas for creating thin films out of gallium arsenide.

BU is, of course, seeking an immediate halt to distribution of the products and lots of damages and fees.
