Abstract
Abstract An indexing system for file folders of the type having a tab along one edge includes a pattern of variable length fields formed on the tab. Each field carries indicia of a size proportionate to the field length. The indicia are visible along the edge of a folder placed in storage. When a series of folders are juxtaposed the indicia combine to form a visual pattern which directs a user's eye to the proper location for removing or replacing a particular folder. The indicia comprise color-coded bars which readily create the visual pattern.

Claim 1
Independent Claim
110 words
An indexing system for file folders of the type having a front panel and a rear panel, the panels being connected along a fold line and a portion of one panel extending beyond the other to form a tab, the indexing system comprising a pattern of different length fields on the tab, each field carrying indicia, the indicia having a size substantially equal to the field length and being visible on a folder placed in storage such that when a series of folders are juxtaposed the variable lengths of the indicia combine to create a visual pattern which directs a user's eye to the proper position of an individual folder.
Claim 2
Dependent Claim
