Google expanded its Open Patent Non-Assertion (OPN) Pledge Tuesday, committing to not sue users, distributors or open-source developers over patent infringement for “patents related to technologies that help deliver fast, secure experiences on the web, including encryption, XML parsing and prefetching,” it said in a Tuesday night blog post (http://bit.ly/1tcqD5d).
