The United States Supreme Court has issued a ruling in a patent litigation case that will make it more difficult for patents on cryptosystems and cryptographic algorithms. The KSR International Co. v. Teleflex Inc. ruling raises the bar on applicant proof that an invention is “non-obvious”.

John Young’s Cryptome website has been shut down by its service provider. Over the years Cryptome has provided valuable insights into the history and development of cryptographic science as well as attempts to limit and control the use of cryptographic technology. Cryptome, and Young personally, were often under pressure from the United States and Foreign Governments to remove content and cease operation.

Update: Cryptome appears to be back up.
