PatentCafe Announces Language-based OSS Patent Search Engine

Initially populated with IBM's 500 pledged software patents, PatentCafe announced the opening of its Open Source Software (OSS) Patent Search Engine for worldwide search access of OSS patents. Now, through PatentCafe's new OSS Patent Search Engine software developers can search this collection of OSS patents, and find the patents most related to their software projects.

IBM pledged open access to key innovations covered by 500 IBM software patents to people and groups working on open source software that meet the Open Source Initiative.

The Latent Semantic Analysis search engine technology creates a hierarchical list of results with the most relevant patents ranked first.
