yes, it is foot for applying an invisible zipper. I don't know that it is brand exclusive. I have the same one and it works with my Viking. They came in a package with several plastic versions to fit different machines. One for straight shank, slanted shank and a couple others. I loved the invisible zipper but have set aside all garment making and just quilt now. So my special zipper foot is sitting the bottom of my accessories case, growing old and dusty from lack of use.
