The staff of Välinge Innovation invented the first laminate
flooring in the world in March 1977, at that time employed by Perstorp
AB. They were also responsible for the further development and
market introduction during the period 1977 - 1981.
Välinge invented the first mechanical locking
system for thin floating floorings and applied for the first patent
in March 1993.
Välinge has since then developed the locking
system, the installation methods and the production equipment considerably.
Several types of laminate and wood floorings could be produced
with mechanical locking systems. The production technologies are
very advanced and cost efficient.
|
 |
Välinge's intellectual property is protected
by several different patents, granted in countries all over the
world. Additional patents are applied
for.
The patents and patent applications consist of different inventions.
Similar applications have and will be made in several other countries.
The patents and patent applications protects and specifies a variety
of mechanical locking systems, several production methods and installation
methods.
The technologies disclosed in the granted patents and the published
patent applications are now "known technology" and are comprised
in the "state of the art", and can therefore not be patented by
anyone else.
The first laminate flooring with a mechanical locking system -
Alloc® - was introduced in January 1996 by one of our licensees,
Alloc AS (at that time Norske Skog Flooring AS) at the Domotex
fair in Hannover.

State-of-the-Art Patent Portfolio
Välinge has been granted more US
and EPO patents
related mechanical locking technology than any other company
in the flooring industry. Välinge's current patent portfolio
is about 20 patents in United States and over 400 worldwide
Each Välinge patent family generally contains several independent
inventions. Based on the present applications pending, we estimate that
about 20-30 new US and EPO patents will be granted within 2-3 years.
The aim is to create 3-5 new patent families each year and hopefully even
more with our extensive research and development resources. |
