"While we recognises the legitimate rights of intellectual property rights owners, we regret recent incidents of patent holders abuse and unsubstantiated use of their rights against open source/free software developers. A recent development, which deserves the careful attention from the Commission, is the use of unsubstantiated threats of intellectual property rights infringements against those who attempt to develop interoperable software products. As an example, a major software company has publicly stated that it believes Linux and other open source software infringes 235 of its patents, but has never identified any of these patents. Vague claims by patent holders that open source software may infringe their patent rights should be obliged to identify supposedly infringed patents or cease to make unsubstantiated allegations. This would prevent patents from being invoked to spread fear, uncertainty and doubt ("FUD") against open source software products in the minds of both developers and users. The behaviour of creating FUD against open source software solutions should not be tolerated, as it amounts to an anticompetitive strategy aimed at distorting conditions in the marketplace to the detriment of OSS products."
