Id say the biggest date for AVOI is June 21st
That is the Markman Hearing date (see below in red): if you want the definition of a markman hearing and why its important I posted it on the QPRC board earlier this am as they have a Markman conference tomorrow against AMAZON, and similarly enough are currently suing APPLE in East Texas on a separate patent.
FROM AVOI courtlistener listings:
