On April 26, 2016 , the USPTO issued U.S. Patent Number 9,321,585 to EndoChoice, Inc., which was successfully prosecuted by Novel IP.
The '585 patent is directed towards combined drape and carrying bag unit used in medical and surgical settings with an indicator attached to a drawstring of the unit. Conversion of the unit from a drape or mat configuration involves pulling on exposed drawstring sections and results in deployment of the identifying indicator. The indicator includes preprinted information, a barcode for scanning, and/or space for the inscription of information by medical personnel. The inclusion of an integrated indicator with the combined drape and carrying bag unit informs medical personnel of the contents of the unit when in the bag configuration and obviates the need for opening the bag and discovering its contents, thereby reducing exposure of medical personnel to biohazard waste.
Independent Claim 1 describes " A device for identifying contents of a combined drape and carrying bag unit, comprising an octogonally shaped drape and carrying bag unit having a centrally positioned rectangular absorbent mat having a first, mat configuration and a second, carrying bag configuration; a drawstring extending around a periphery of said drape and carrying bag unit and contained within a drawstring casing, for use in medical and surgical settings, comprising an indicator fixedly attached to a portion of said drawstring, wherein said indicator is compressed and hidden in the drawstring casing while said drape and carrying bag unit is in the first, mat configuration and said indicator is deployed and exposed outside the drawstring casing when said drape and carrying bag unit is converted into the second, carrying bag configuration, wherein conversion of said unit from said first configuration to said second configuration results in said indicator automatically becoming deployed and exposed from said drawstring casing through at least one of said drawstring access openings, wherein said drape and carrying bag unit is converted from the first, mat configuration into the second, carrying bag configuration by pulling the drawstring through at least one space in the drawstring casing, and wherein, when the unit is in the first, mat configuration, the indicator is positioned along the drawstring approximately 20-60 cm from the at least one space.
