In 2011 alone, Willis’s One Plug Tree has 16 Design and Utility Patents pending. These are all crucial patents that are driving the industry innovation.
- In 1993, Willis’s wire factory began to manufacture wire for Christmas lights. In 1994, Willis worked jointly with Sumitomo Wiring Group from Japan to upgrade its technology and machines to manufacture wire for Office Appliance use. Currently, the wire facility contributes 1/3 of the corporation’s sales volume.
- In 2004, Willis expanded its facility and began to manufacture pre-lit trees. Willis Pre-Lit Tree is now the fastest growing category for Willis with various beautiful tree styles, reliable lights, user friendly inventions and competitive pricings.
- In addition, Willis initiated the design and development of plastic products such as Easter eggs and bird feeders.
- In 2010, Willis has acquired a plug company and lunched to start its line of Extension Cords with UL listing and testing equipment ready.
- The company takes pride in constantly improving its facilities with new machines and new “Know How’s”.
