The recent IPR Victories for RightQuestion, LLC Mark the Firm’s 15th Consecutive Victory in the PTAB

Continuing its series of victories enforcing its clients’ patents, Kramer Alberti secured three important wins in inter partes review proceedings in the Patent Office for client RightQuestion, LLC. The firm won denial of institution on three IPR petitions filed by AT&T, Verizon Wireless, and Nokia. This latest victory at the PTAB marked the 15th consecutive IPR win for Kramer Alberti and its clients in important and high-profile decisions.

RightQuestion was founded by pioneering inventor, Dr. Bjorn Markus Jakobsson, who developed technologies solving fundamental problems encountered by users of cell phones and telecommunications networks. His patented inventions provide innovative solutions for protecting consumers from fraudulent and unwanted calls, such as “spoofed” calls, spam calls, and robocalls. In February 2024, Jakobsson’s company, RightQuestion, LLC, filed patent infringement cases against telecommunication giants AT&T and Verizon in the federal court in Texas, asserting infringement of its patents, and seeking to prevent the continuing unauthorized use of its technologies.  AT&T and Verizon, in turn, filed IPR challenges in the Patent Office seeking to invalidate RightQuestion’s patents. Kramer Alberti has now won denial of institution, clearing the way for RightQuestion, to go to trial against AT&T and Verizon in the federal court in Texas in October 2025.

“The rulings in the RightQuestion IPRs are two-fold. First, they validate our client’s patent legitimacy, and second, effectively close AT&T, Verizon and their co-petitioner’s misguided challenge to Dr. Jakobsson’s patents, clearing the way for the federal court trials that our team will conduct this fall in Texas,” stated Rob Kramer, lead counsel for RightQuestion. “Our team delivered a decisive victory for our client, and against some of the largest telecom companies,” continued Kramer Alberti partner Nicki Glauser.
