Those who are in favor of open source frequently become near apoplectic at the thought that open source software can be, and in fact should be, patented. The reality is that forward thinking companies that operate in the open source space do make use of the patent system. A quick search of Freepatentsonline.com shows that Red Hat, Inc., one of the preeminent open source companies in the world, is named as the assignee on some 263 US patents or US patent applications. So if you are about to make an enormous mistake and listen to the “open source means free” community, ask yourself why a highly successful company like Red Hat uses the patent system and acquires patents. If patents are good for Red Hat, an open source company not at all enamored with the existence of software patents, then why are software patents bad for you? Shouldn’t you model your business off successful companies?
