The “on-sale” bar to patentability refers to a sale or offer for sale of an invention that can invalidate the patent for that invention. The America-Invents-Act (AIA), which altered the language in the statutes that apply to the on-sale bar, has made it difficult to determine what actions might constitute a “sale” or an “offer for sale” under current law. Nevertheless, a clear understanding of the on-sale bar is necessary to enable entities of all sizes—from single inventors to large corporations—to effectively monitor activities surrounding their inventions, and to enable attorneys to provide such entities with accurate and useful advice.
