RealNetworks said it has prevailed in a patent infringement lawsuit brought against it by Ethos Technologies, a Boston-based digital delivery company. According to RealNetworks, the lawsuit related to some of its minor products, including RealDownload, which the company hasn't distributed for several years.

After a four-week trial, a jury in Boston decided this morning that RealNetworks didn't infringe on any of the 10 patent claims brought by Ethos. In fact, the jury invalidated seven of those claims.
