Melissa Schwaller's article titled “Effect of the Date of the First Use in Commerce on Patent Validity Under the On Sale Bar/Public Use Bar” appeared in the October 2015 American Intellectual Property Law Association's Patent Law Committee Newsletter. The article discusses whether the date listed for the first use in commerce in a trademark application that is earlier than one year before the filing of the patent application affects the validity of the patent under the on sale bar/public use bar on a good or service covered by the mark and patent claims.
