Relax. I believe Microsoft has no intention of enforcing this patent against anyone, and no intention of collecting royalties on it. Microsoft is not pretending that they invented RSS…just protecting itself against potential patent infringement lawsuits from »shell companies« and »patent trolls« who do nothing but sue big companies. Sad to say this is the current state of the patent system.
Puhh, da bin ich aber nun wirklich beruhigt.
