Context: Wilus and Amazon have been in talks over a potential license to the former’s Wi-Fi technologies since 2022. The latter has not yet publicly signed many licensing deals with Wi-Fi standard-essential patent (SEP) owners, aside from Huawei, which only came after pressure from a major court case in Germany and a preliminary injunction (PI) (December 26, 2023 ip fray article). The two settled in March 2024 with a bilateral licensing agreement (March 5, 2024 ip fray article). A redacted version of the PI judgment later became available, and it showed that the Munich I Regional Court had actually considered Huawei overcompliant with its fair, reasonable, and non-discriminatory (FRAND) licensing obligations (March 19, 2024 ip fray article).
What’s new: Wilus has sued Amazon for infringing one of its European Wi-Fi 6 SEPs in the Munich I Regional Court.
Direct impact: The complaint, which was filed on October 23, 2026, enforces the same patent Wilus successfully enforced against ASUS, which resulted in a Germany-wide injunction (January 30, 2026 ip fray article). That dispute was resolved with ASUS taking a license to the Sisvel Wi-Fi Multimode patent pool in May (May 19, 2026 ip fray article). The two main SEPs enforced in that case were EP3512289 (“Wireless communication method using enhanced distributed channel access, and wireless communication terminal using same”) and EP3849157 (“Wireless communication method and wireless communication terminal, which use discontinuous channel”).
Wider ramifications: Depending on the outcome of this suit, and should Amazon ultimately take a license, it would join Cisco, Hewlett Packard Enterprise (April 8, 2026 ip fray article), HP, Lenovo, LG Electronics, Microsoft (June 30, 2026 ip fray article), Samsung (July 14, 2026 ip fray article), and Sony – some of which have obtained the right to use Wilus’ patented Wi-Fi technologies through a bilateral agreement, or through the Sisvel Wi-Fi Multimode pool.
In a statement today, Wilus founder and CEO Jin Sam Kwak said:
“We always seek to reach licensing agreements without litigation, but maintaining a level playing field requires us to act when a company of Amazon’s size and scope fails to obtain rights that we have licensed so widely to the industry. The royalties generated by our SEP portfolios, including through the Sisvel Wi-Fi Multimode pool, are critical to supporting our ongoing R&D activities in wireless technologies.”
