Feds Reject Eolas Browser Plug-In Patent

theodp writes "The USPTO has issued a preliminary decision invalidating Eolas' claim to Web browser technology central to a case against Microsoft, which could save the software giant more than half a billion dollars in damages. If upheld, this also means Microsoft will not be required to make changes that would have crippled IE's ability to work with plug-ins like QuickTime and Flash. Eolas has 60 days to respond to the decision. The USPTO has only invalidated 151 patents out of nearly 4 million patents awarded since 1988."
