VPLM hasn't stalled a thing!! Apple (and others) are using the IPRs as a "stall" tactic. It's what they do for all infringement suits. Their goal is to eliminate all those without a strong case or those whose finances can't handle the strain (who they can financially bully into going away). VoIP-Pal has been diligent in every lawsuit, filing, and response. Zero stalling on their part. No matter the outcome, I commend the voracity of VP's fight. They are doing everything they can think of to win this fight for both them and the shareholders.
