Bruce Perens writes "We've warned you for a decade. Now the monster has finally arrived: patent holders are filing suit against OSS developers." From the article: "We should not be confident that we will continue to have the right to use and develop Open Source software. A coordinated patent attack by a few companies, or even one large company, could completely destroy Open Source in the United States and cripple it in other nations. Funds and patent portfolios that have been established to help defend Open Source would not be sufficient to defend it. Only legislative changes to the patent system can fully protect Open Source and maintain it as a viable source of innovation for our future."
