Publicly traded VoIP-Pal.com, Inc. has followed its recently filed, second case against Apple with a first case filed against Amazon (2:18-cv-01076), both in the District of Nevada. Each complaint asserts the same four patents, all issued within the last year or so and all generally related to routing messages between private and public networks based on stored caller profiles. At issue in the Amazon complaint are Alexa’s calling and messaging features, together with various other devices either provided by Amazon (e.g., Amazon Echo, Amazon Tap) or equipped with the Alexa app (e.g., certain Android mobile phones, Apple iOS mobile phones). This recent activity seems to have been triggered by final written decisions in two inter partes reviews (IPRs) of patents previously asserted against Apple (and others), sustaining all of the claims challenged. However, those proceedings have yet to conclude, with Apple seeking to reverse those judgments as a sanction against VoIP-Pal for allegedly improper communications with the Patent Trial and Appeal Board (PTAB).
