Finnish handset maker says neither Asus nor Google has approached it to license wireless-standard patents.
Announced just last week, the Nexus 7 tablet is already attracting patent-infringement claims.
Google unveiled the Asus-built 7-inch device running Android's new mobile OS, Jelly Bean, at Google I/O in San Francisco. However, Nokia alleges that the Nexus takes advantage of Wi-Fi technology covered by Nokia patents that neither Google nor Asus approached the Finnish handset maker about licensing.
"Nokia has more than 40 licensees, mainly for its standards essential patent portfolio, including most of the mobile device manufacturers," a Nokia spokesperson told The Inquirer. "Neither Google nor Asus is licensed under our patent portfolio."
"Companies who are not yet licensed under our standard essential patents should simply approach us and sign up for a license," the spokesperson said.
CNET has contacted Asus and Google for comment and will update this report when we learn more.
