"As part of the Linux Defender program, the OIN will look at issued patents in an effort called the post issue Peer to Patent effort. If warranted, the OIN would help challenge an already issued patent if it believes it is invalid based on information it has or is made aware of by the open source community.
"The Linux Defender effort will also do peer review of pending patent publications in an effort to help validate that a patent application is non-obvious and has not already been invented.
"Linux Defender will also engage in a practice known as Defensive Publications. A Defensive Publication is a set of documents that describes a production or method, which could then become a source for defining prior art in the patent awarding process. Applicants for U.S. Patents are expected to show that their invention is obvious and original. The Linux Defender Defensive Publications effort is an attempt to identify everything that has already been invented by open source and Linux technologies."
