On June 07, 2016 , the USPTO issued U.S. Patent Number 9,360,129 to Fresenius Medical Care Holdings, Inc., which was successfully prosecuted by Novel IP.

The '129 patent  is directed towards a valve that has an orifice closing member adjacent to an orifice through which fluid can flow, a displacement member having a first portion and a second portion, where the first portion is adjacent to the orifice closing member when the valve is in an open position, a first magnet and a second magnet where the first and second magnets are sufficiently proximate to the displacement member to exert a magnetic force on the displacement member, and an actuator for generating a magnetic field to move the displacement member toward the first magnet, cause the first portion to press against the orifice closing member, and cause the orifice closing member to close the orifice.

Independent Claim 1 describes " A valve comprising: a first magnet having a first pole and adapted to generate a magnetic field; a second magnet having a second pole and adapted to generate a magnetic field, wherein said first magnet is larger than said second magnet; a coil positioned within the valve, wherein the first magnet is positioned at one end of the coil and the second magnet is positioned at a second end of the coil; and a moveable displacement member comprising an elastic material, a rod having an end, a ferromagnetic material positioned around said rod; and a housing enclosing the end of the rod and said elastic material, wherein: the end of the rod and the elastic material are separated by a gap when the valve is in a second state and are not separated by the gap when the valve is in a first state; the moveable displacement member is adapted to be positioned adjacent at least one orifice and configured to move within said coil between the first state and the second state, wherein the move between the first state and the second state is effectuated by a change in current to said coil which, in turn, causes the magnetic fields associated with the first magnet and the second magnet to change and, accordingly, causes said ferromagnetic material to move between the first magnet and the second magnet, and wherein said magnetic fields maintain each of said first and second state without additional energy input; and the first magnet is positioned closer to the at least one orifice than the second magnet.
