Patented Locks and Design Patent

Patented Locks and Key Control Systems have been chosen by millions of clients in many countries who are seeking a high level security key system.

The Patented Locks provide enhanced key control and the very best high-security solution by the Design Patent. What is Design Patent? The design patent is the protection of the key profile's design or the patented key system's design features. The patent life is the length of time under protection that the key system has left to run on the patented design. When the design of a patented key system has run out then other manufacturers can start producing the key blanks and parts which increases the possibility of someone duplicating your keys. To achieve the very best high-security the Patented Locks and high level master key systems require a dedicated machine just for that type of key system. This will restrict other people from duplicating your keys well beyond the end of a design patent expiring. Our patented locks and locking systems are patent protected for decades, achieving reliable patent protection well into the future.
