According to a recent announcement from Laird Technologies, the company won its patent infringement lawsuit filed at the Seoul High Court in Korea against SB Telecom in August 2002 for infringement of its antenna patents registered in Korea related to retractable antennas used in mobile phones. In response to Laird Technologies' suit, SB Telecom filed two pairs of suits in October 2002 and November 2002, respectively, seeking to invalidate the patents and to confirm the scope of the patents.

As a result of the invalidation proceedings, Laird Technologies received favorable decisions from the Korean Supreme Court that the patents are valid with unchanged claims, said the developer. The Supreme Court also confirmed that the half wave products in question were within the scope of the patents, according to the release. Following these decisions, the Seoul High Court ruled that SB Telecom did infringe on Laird Technologies’ intellectual property rights. Compensation for financial damages are being sought from SB Telecom.
