Clearwire Sued for Patent Infringement

A Dallas-based company has filed a lawsuit against Clearwire Corp. and Sprint Nextel Corp., alleging patent infringement related to the use of six patents held by Adaptix Inc., which has filed the lawsuit.

Adaptix says its patents on multi-carrier communications with group-based subcarrier-cluster allocation, adaptive subcarrier-cluster configuration and selected loading, medium access control for orthogonal frequency division multiple access, multi-carrier communications with adaptive cluster configuration and switching and adaptive subcarrier cluster configuration and selective loading are being infringed.

As is the case with such high-profile cases, it is doubtful the issue will result in a shutdown of the Clearwire network, though that cannot be discounted as a possibility if the parties cannot agree on a settlement.
