Laird Technologies wins patent dispute

Laird Technologies recently won its patent infringement lawsuit filed at the Seoul High Court against SB Telecom for infringement of Laird Technologies’ antenna patents registered in Korea.


Laird Technologies recently won its patent infringement lawsuit filed at the Seoul High Court in Korea against SB Telecom in August 2002.



Laird Technologies brought the case against SB Telecom for infringement of 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 favourable decisions from the Korean Supreme Court that the patents are valid with unchanged claims.



The Supreme Court also confirmed that the half wave products in question were within the scope of the patents. Following these decisions, the Seoul High Court ruled that SB Telecom did infringe on Laird Technologies’ Intellectual Property Rights (IPRs).


Compensation for financial damages are being sought from SB Telecom.
