`
`RAFFEL SYSTEMS, LLC v. MAN WAH HOLDINGS LIMITED
`
` ______________________
`
`Before REYNA, HUGHES, and STOLL, Circuit Judges.
`PER CURIAM.
`
`Raffel Systems, LLC appeals the decision of the Patent
`Trial and Appeal Board concluding that claim 1 of U.S. Pa-
`tent No. D821,986 is unpatentable under the on-sale bar.
`The Board found that an email sent by patent owner Raffel
`offered for sale an embodiment of the claim in small quan-
`tities on-demand over a year before the priority date of the
`patent. We have considered the appellant’s arguments that
`the Board’s on-sale determination was unsupported by sub-
`stantial evidence and find them unpersuasive. We there-
`fore affirm.
