After VOIP-Pal filed near-simultaneous lawsuits against tech giants Facebook, Amazon, Apple, and Google, Twitter has turned the tables, filing a complaint for declaratory judgment against VOIP-Pal. They argued that the claims made in the new suits are similar to a previous case, which VOIP-Pal lost. Twitter has requested a declaratory judgment of noninfringement in relation to U.S. Patent No. 10,218,606. Twitter states that the patent is “a member of a family that includes six other patents that VOIP-Pal has asserted in prior lawsuits in this Court against Twitter, Apple, AT&T, Verizon Wireless and Amazon (‘first and second wave actions’). The patent shares a common specification with the six previously-asserted patents. All six of the previously-asserted patents were found to be invalid for claiming ineligible subject matter.”
