To raise funds for research and development, start-ups sometimes have to announce the existence of licensing agreements, supply and distribution agreements etc. (i.e. a contract for a future sale of a product embodying an invention). In places like the US, if such agreements were made public more than one year prior to the effective filing date, even though the details of the invention are kept confidential, a statutory on-sale bar may be triggered, resulting in loss of patent protection for the invention in the US.
