The Problem
In 2022, Atlas Global Technology sued Acer, asserting that Acer infringed on nine of its patents, which Atlas claimed were essential to the 802.11ax (Wi-Fi 6) standard. The asserted patents were U.S 9,531,520, U.S 9,763,259, U.S 9,825,738, U.S 9,848,442, U.S 9,912,513, U.S 9,917,679, U.S 10,020,919, U.S 10,153,886, and U.S 10,756,851. Acer was represented by our client, a law firm, to defend its case. As part of the defense preparation, our client reached out to us to rebut infringement contentions and prepare invalidity reports for each patent, focusing specifically on contribution documents related to Wi-Fi technology.
HOW WE SOLVED IT
Our team conducted a detailed review of the claim charts prepared by Atlas Global Technology. We analyzed how each of the nine asserted patents mapped to the 802.11ax (Wi-Fi 6) standard and prepared a strategy and list of parameters to consider while reviewing.
Our team reviewed each claim chart diligently, paying special attention to evidence mapping with the claim elements. We found discrepancies in some of the claim charts where the claim elements did not align with the Wi-Fi 6 standard. Specifically, some claimed features were articulated from a 5G perspective, were broadly mapped, or were not present in the Wi-Fi 6 standard.
Our team also conducted a thorough prior art search in two phases to assess the validity of the asserted patents.

We performed comprehensive research within the internal database, containing technical standards and specifications for Wi-Fi and 3GPP, to identify and review all pertinent documents published before the priority dates of the nine asserted patents.
A comprehensive search of patent documents was conducted by utilizing various commercial databases to identify any prior patent applications or granted patents with priority dates before the priority dates of the asserted patents. This phase aimed to uncover any existing patents that might disclose similar technologies or concepts, potentially impacting the validity of the patents asserted by Atlas Global Technology.
Our reports provided substantial material to our client to formulate a strong defense against the alleged infringement claims. They revealed that the patent claims did not perfectly align with the 802.11ax standard, creating weaknesses in the infringement allegations. The comprehensive report offered a clear understanding of the findings and recommendations, enabling them to make informed decisions.
