Voip-Pal.com (VPLM) sued Amazon.com (AMZN) on June 15, 2018 in the District of Nevada. According to a press release issued by Voip-Pal, CEO Emil Malak highlighted the difficulty in even getting large corporations to respond to licensing discussions, saying:
Our patents have more than nine years term remaining during which time others cannot lawfully use our patented technologies without a license. Our preference has always been to avoid litigation. However, given the unresponsiveness of corporate giants in licensing our patents, we feel our best option is to seek fair compensation for the use of our intellectual property through the Courts. If we are unable to reach an amicable settlement with Amazon and the other companies with which we are already engaged in legal actions — Apple, AT&T, Verizon and Twitter — we are prepared to stay the course until we have monetized our patents.
