1) Open standards are important for enabling innovation, boosting transparency, avoiding lock-in, and ensuring economic growth. They facilitate interoperability between software. 2) For a standard to be considered truly open, the intellectual property covering the standard must be made irrevocably available on a royalty-free basis. There should also be no constraints on reusing the standard. 3) Ensuring transparency in patent licensing and favoring ex ante over ex post disclosure of intellectual property terms is important for preventing obstacles in the software industry and allowing interoperability through open standards.
