Patents granted in most countries worldwide, including Europe, Canada, United States, Russia and China

 

Our patented designs differ from all existing profile designs. International patents and patent applications for I4F’s technologies have been granted and filed in over 100 countries worldwide. Non-infringement studies in Europe and the United States, issued by independent groups of IP  attorneys have confirmed their strength.

Our locking system:

  •  3L TripleLock®: a one piece drop-lock system for the short side that eliminates the need for additional plastic inserts
  • Click4U®: an angle-system for the long side combined with 3L TripleLock on the short side
