Patent Buzz

There is no lack of buzz around patents. This article garnered opinions from some big names in the patent world, like Free Software Foundation counsel Dan Ravicher, law firms Phillips Fox and Baker & McKenzie.

Dan Ravicher of the FSF made this point: "patents pose less of a threat to open-source software than they do to proprietary software". He also states: "There are no patents that choose only to be infringed by open source. Any patent that imposes a threat to open-source software is going to impose a threat to proprietary software."

Well, the first point doesn't flow logically from the second point. Open source and proprietary software are in two different categories, from an evidientiary and a monetary point of view.

Access to source code
As a matter of evidence, violating patents in open source software is evident on its face: you can read the source code. Legible code makes a patent infringement case trivial. Proprietary software may require expensive reverse engineering, to devise how it operates and whether that operation violates the patent. There may be some legal questions regarding your capacity to reverse engineer legally, particularly with oppressive legislation such as the DMCA.

Access to software
Also, in this vein, to determine a violation of proprietary software, you must also have access to it. Proprietary software, particularly custom or enterprise software, may not be readily available to examine. Even if the software is available, it may require an onerous license that prohibits reverse engineering. Open source software is, almost by definition, accessible to anyone for examinition. Having a clause to prevent reverse engineering would be contrary to its object.

Licensing capacity
The lucid nature of open source software means that to obtain a mandatory license for a patent would be prohibitively expensive for two reasons. First, open source software does not have deep pockets or the capacity for a cross licensing agreement. Second, even if either were available, the nature of open source software would wholly undermine the purpose of the patent: an open source implementation of the patent would be available for free, unrestricted use.

A proprietary software company, on the other hand, has the economic means and an economic incentive to obtain a license or cross license, and would presumably do so only for the benefit of the company, and would not threaten the other economic interests of the patent.

Compulsory Licensing
Patent legislation provides for compulsory licensing, I understand, if it is in the public interest. However, even though a proprietary company could enforce this licensing by challenging it at the patent office, currently the cost would be prohibitively expensive to many, if not most, open source software developers. As well, compulsory licensing that undermines the patent, by creating an open source unrestricted implementation, would create contentious arguments about the real public interest. Patents protect the patentor, and as a secondary consideration they may have licensing imposed against the will of the patentor, if it is in the public interest. Their rights would likely trump.

For at least these reasons open source software is in a different situation than proprietary software, and I am not entirely convinced of Mr. Ravichers's assertion, as they are quoted in the linked article.
