A Patent Troll Bites the Dust

One of the worst of the parasite, Eolas, has had its patents invalidated:

The inventor of the Web, Tim Berners-Lee, had never testified in court before last year. In February 2012, he left Cambridge to fly down to Tyler, an East Texas city of about 100,000, to testify at a patent trial. It was the culmination of a bold campaign by a man named Michael Doyle to levy a vast patent tax on the modern web.

Berners-Lee was one of several web pioneers who came through the court during the course of a four-day trial, which ultimately convinced a jury to invalidate two patents owned by Eolas, the tiny patent-holding company that Doyle and his lawyers transformed into one of the most fearsome "patent trolls" of all time.

Now Eolas appears to be gone for good. The company mounted a lengthy appeal, but it was all for naught; this morning, a three-judge appeals panel affirmed the jury's verdict without comment.

Pei-Yuan Wei created the pioneering Viola browser, a key piece of prior art, while he was a student at UC-Berkeley in the early 1990s. Scott Silvey, another UC-Berkeley student at that time, testified about a program he made called VPlot, which allowed users to rotate an image of an airplane using Wei's browser. VPlot and Viola were demonstrated to Sun Microsystems in May 1993, months before Doyle claimed to have conceived of his invention.

Eolas claimed an tremendously broad patent on all forms of interactive web products.

Why the f%$# has Eolas been able to blackmail people for so long?

Seriously.
