Judge Seals LG Complaint Against Owner of Patents on AMR-WB Speech Codec 

U.S. District Judge Paul Oetken in Manhattan ordered sealed Wednesday an unspecified contract complaint that LG Electronics filed against St. Lawrence Communications, owner of patents germane to the adaptive multi-rate wideband (AMR-WB) speech codec for cellphones, court records (in Pacer) show. SLC filed 10 patent infringement complaints against various carriers and smartphone OEMs since 2014, all but one in U.S. District Court in Marshall, Texas, records show. In a November 2014 complaint (in Pacer), SLC accused LG of violating five patents on AMR-WB-enabled HD Voice technology. LG countersued (in Pacer) in August 2015 seeking declaratory judgments that it was innocent of infringement and accusing SLC of licensing its patents on terms that weren't fair, reasonable and nondiscriminatory. LG and SLC appeared to settle that dispute in January 2016, records show. Neither company commented Wednesday.
