The No-Bump Shower Filter Patent Suit

Earlier this month, Sprite Industries sued Culligan in the Central District of California for infringement of a patent on a shower filtration device.  The patent covers a combination showerhead and water filter held together in a single housing.  The housing has top and bottom mating halves that are either screwed together or threaded together, a water filter assembly secured in the housing and a baffle to direct the water flow through the filter.  The patented device reduces potential head bumps to the bather because it takes up less shower space than prior art devices, which typically required that a separate shower head be attached to a filter outlet.  The accused device is Culligan’s wall-mount filtered showerhead.
