2 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.

AFFIRMED
