Conex Bänninger and RLS settle fixings patent dispute

Flame-free jointing companies settle patent design dispute without admission of liability or infringement


Conex has modified the design for its >B< MaxiPro fitting, following a settled dispute over patent infringement with another flame-free jointing manufacturer. Group company Conex Universal said it has settled the patent infringement lawsuits filed against it by RLS LLC, without admission of liability or infringement.

RLS, filed a US. lawsuit on January 22, 2018, alleging that Conex infringed a US patent relating to its Rapid Locking System crimp fittings, then followed it with a UK lawsuit on May 20, 2019, alleging that Conex infringed its European patent. Conex denied infringement and alleged that RLS’s patents are invalid.  RLS makes crimp fittings sold by Parker Sporlan for the Zoomlock brand.

The two parties have now agreed to settle the dispute and to dismiss all of their claims against each other. Without admitting liability or infringement, Conex has modified its design and, after June 30, 2019, will no longer sell the previous design accused of infringement. 

RLS, for its part, maintains it manufactures the only ’patented press-to-connect, flame-free fittings for joining copper or aluminum lines in high-pressure air conditioning and refrigeration applications.’.’
