SW2 wireless mobile column lift systems manufactured in France by Sefac S.A. and distributed in the U.S. by Sefac U.S.A. Inc. are the subject of two patent infringement lawsuits brought by Gray Manufacturing Company in the United States District Court for the Eastern District of Pennsylvania. In those lawsuits, Gray Manufacturing alleges that the SW2 lift systems and the use of those lift systems infringe U.S. Patent No. RE41,554, U.S. Patent No. 7,014,012, and the recently issued U.S. Patent No. 10,214,403.

Gray Manufacturing intends to aggressively assert those patents against all infringers, including by bringing infringement actions against anyone who purchases and uses Sefac’s SW2 lift systems.
