JPEG Patent Claim Surrendered! (Groklaw)
Here you go, straight from the Public Patent Foundation's press release: Forgent Networks has stopped asserting its patent against JPEG, has dropped all its pending cases that were asserting the patent, and says that it won't file any other infringement claims based on the patent. You'll recall that PubPat challenged the patent last year and the USPTO reexamination led to rejection of the broadest claims."
