On December 9, 2015 , the USPTO issued U.S. Patent Number 9,220,485 to Endochoice, Inc., which was successfully prosecuted by Novel IP.

The '485 patent is directed towards an improved tissue specimen trapping device for collecting and separating solid particles and materials from body fluids.  It has a porous separator that rests on a shelf-like annular ledge between upper and lower portions of the tissue collection container. At least one tissue collection basket removably disposed in the tissue collection container above the separator shelf has a porous bottom surface to filter tissue specimens from body fluids and has downward projections to the tissue collection basket above the separator shelf to create a space therebetween.

Independent Claim 1 describes "a collection and separation device for use in combination with a suction source to withdraw body fluids and collect tissue specimens from a patient, comprising: a container having an upper portion, defined by a first volume, and a lower portion, defined by a second volume; a lid adapted to fit onto the upper portion of the container, wherein the lid comprises a first conduit for receiving said body fluids and tissue specimens; a planar porous separator horizontally positioned between the upper portion and lower portions, wherein the porous separator is configured to filter and maintain the tissue specimens in the first volume while permitting said body fluids to flow into the second volume; and a first tissue collection basket having a plurality of sides and a horizontally planar base having a plurality of holes, said horizontally planar base configured to define a bottom of the first tissue collection basket, and at least one downward projection, wherein, when the first tissue collection basket is positioned within the first volume and on top of the porous separator, the at least one downward projection is configured to create a space between the porous separator and the horizontally planar base."
