US-based Cree has filed patent infringement lawsuits with the US District Court for the Western District of Wisconsin against Taiwan-based LED packaging houses Harvatek and Kingbright Electronics, according to the company.
The infringed patents are US Patent Nos. 6,600,175, 7,943,945 and 8,659,034 concerning white-light LEDs, Nos. 7,910,938 and 8,766,298 concerning LEDs and No. 8,362,605 concerning apparatus and method for use in mounting electronic elements, Cree said.
In response to the charges, Harvatek indicated that it has received notice from Cree's attorneys at law but has not yet received formal documents from the court. Harvatek emphasized that it always respects other companies' intellectual property and has no intension of infringing other companies' patents. While Harvatek focuses on the Asia market, its products involved in the accusations are very low volume and therefore the lawsuit will not have a substantial operational and financial impact, the company said.
