Against Software Patents

February 28, 1991
The League for Programming Freedom

Software patents threaten to devastate America's computer industry. Patents granted in the past decade are now being used to attackcompanies such as the Lotus Development Corporation for selling programs that they have independently developed. Soon new companies will often be barred from the software arena--most major programs will require licenses for dozens of patents, and this will make them infeasible. This problem has only one solution: software patents must be eliminated.
