2009年9月18日,地板工业公司与四川升达林业产业股份有限公司达成了世界范围内的专利授权协议,授权四川升达使用Unlin公司的无胶锁扣专利技术。

地板工业公司欢迎升达公司加入其在中国国内市场上不断壮大的专利用户联盟,在中国市场上其他主要的地板制造商,诸如圣象,亚洲木业,吉象木业早前都已经与Unilin公司签署了专利授权协议。

Unilin的技术(无胶锁扣,倒角,表面处理,制作工艺)在中国被8项授权专利和21项申请组成的专利族严密保护。位于北京的国际知识产权局(SIPO)于2008年驳回了针对Unilin专利的无效申请（该申请于2006年提出的），从而确认了Unilin专利族的合法性，这一决定与世界上其他国家的专利管理机构早前作出的决定完全一致。

On the 18th of September 2009, Flooring Industries entered into a world-wide license agreement with Sichuan Shengda Forestry Industrial Company for the use of Unilin’s patented glueless locking technology.

Flooring Industries welcomes Shengda in its growing group of licensed companies active on the Chinese domestic market. The other main players active on this market such as Power Dekor, Asia Dekor and PTP partnered up with Unilin some time ago.

Unilin’s technologies (glueless locking systems, beveled edges, surfaces technologies, manufacturing methods) are protected in China by 8 granted patents and 21 patent applications. The SIPO (State Intellectual Property Office) based in Beijing confirmed the validity of the Unilin''s patent portfolio in 2008 after an attack that was launched in 2006. This decision was in line with previous decisions of patent offices in other parts of the world.
