RAFFEL SYSTEMS LLC v. MAN WAH HOLDINGS LIMITED (2021)

United States Court of Appeals, Federal Circuit.

RAFFEL SYSTEMS, LLC, Appellant v. MAN WAH HOLDINGS LIMITED, Appellee

2020-2126

Decided: June 10, 2021

Before Reyna, Hughes, and Stoll, Circuit Judges. John C. Scheller, Michael Best & Friedrich, LLP, Madison, WI, for appellant. Also represented by Michael Bess, Brianna Jane Siebken, Chicago, IL; David A. Casimir, Tyler Sisk, Casimir Jones, S.C., Middleton, WI. Gary Hnath, Mayer Brown LLP, Washington, DC, for appellee. Also represented by Clark Bakewell, Michael Louis Lindinger, Minh Nguyen-Dang, Nicole A. Saharsky; Hao Tan, Shen Wang, Arch & Lake LLP, Chicago, IL.

Raffel Systems, LLC appeals the decision of the Patent Trial and Appeal Board concluding that claim 1 of U.S. Patent 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 quantities 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 substantial evidence and find them unpersuasive. We therefore affirm.

AFFIRMED

Per Curiam.
