Commonwealth Scientific and Industrial Research Organisation (CSIRO) filed suit against Real Communications, alleging that integrated circuit chips sold by Real Communications for use in products compliant with 802.11 a, g, n, and draft n standards infringe a patent related to wireless LANs.  According to the complaint, the patent-in-suit received ex parte re-examination certificates in March 2011 and July 2012, confirming the patentability of the existing claims and adding additional claims.  In April 2012, Reuters reported that defendants Acer, AT&T, Lenovo, Sony, T-Mobile, and Verizon were to pay $229 million to settle patent suits filed by CSIRO.  CSIRO filed suit against the aforementioned defendants in September 2009 and February 2010 for allegedly infringing the same patent asserted against Real Communications.  The patent-in-suit was issued to CSIRO, Australia’s national science agency, in January 1996.  11/2, Eastern District of Texas, no judge yet assigned, 6:2012cv00842.
