Highlighter is a type of writing instrument that is designed to be used over existing text. The process of applying highlighter over an existing section of text known as “Highlighting”. The inks of Highlighters are often made in bright fluorescent colors that would leave a transparent mark over the existing text, thus making the highlighted section more distinct so it can easily draw attention from readers.
Ideally, using a highlighter would require a user to see a section of text before highlighting which the view would normally be blocked by the hand holding the highlighter. In order to overcome this, the user may angle the grip or adjust the view so that they can see the text before highlighting which can be inconvenient for the user. And without such adjustments would cause the section of text to not accurately or straightly be highlighted. This problem may not be a challenge when using other writing instruments such as a pen or pencil since the hand holding the pen or pencil would not be blocking the view between the user and a writing surface.
The current prior art of highlighters that encompasses a feature to solve this issue is Uni® Promark View highlighter and Sharpie® Clear View Highlighter. Both highlighters have the same feature that is to have a portion of a nib made of a clear transparent material to provide a see-through area for a user. This feature provides a very small see-through area and would not be effective when highlighting a large section of text.
Thus, what is needed is a new highlighter that is designed to overcome the shortcomings of all existing versions of highlighters, that would allow a user to be able to easily see an area of text before highlighting.
According to one embodiment of the invention, a highlighter comprises a housing having a hollow body and an opening, an ink reservoir disposed inside the housing for storing ink, a nib disposed at the opening for distributing ink on a writing surface, an ink feeder disposed inside the housing for transporting ink from the ink reservoir to the nib. The housing further comprises a cut-out section disposed behind the nib to provide a see-through area for a user. Wherein the ink feeder is constructed to conform to the internal space of the housing, thus having its body curved or angled away from the cut-out section of the housing. Alternatively, the housing may comprise a section of its body, behind the nib, made of a clear or transparent material such as plastic to provide a see-through area.
According to an alternative embodiment, a housing of a highlighter comprises a first portion having a hollow body, a second portion having a hollow body and an opening, wherein the second portion connected to the first portion such that the first and the second portions form an angle or a curve, thus creating a see-through area. An ink reservoir is disposed inside the housing for storing ink. A nib is disposed at the opening for distributing ink on a writing surface. An ink feeder is disposed inside the housing for transporting ink from the ink reservoir to the nib. Wherein the ink feeder is made to conform to the internal space of the housing, thus having its body curved or angled due to the curve or angled body of the housing.
In the following description, there are shown and described several embodiments of the invention. It should be realized the disclosed invention is capable of other different embodiments and their details are capable of modification in various, obvious aspects without departing from the spirit and scope of the invention. The drawings and descriptions should be regarded as illustrative in nature and not as restrictive.

Alternatively, the ink feeder 6 can be made of two or more different materials, or the highlighter 1 may comprise more than one ink feeder units that may be made of different materials.
As used herein, the term “Ink feeder” can refer to a portion of a nib, or a portion of an ink reservoir, or a separate unit, or a combination of different units, or a combination of different materials, that provides transportation of ink from an ink reservoir to a nib. And when the nib, the ink feeder, and the ink reservoir are constructed into one single unit, any section of the unit (combined nib, ink feeder and ink reservoir) disposed inside the housing, can be referred to as an “ink feeder”.
The highlighter 1 may comprise a cap 7 to prevent the ink from drying out. The cap 7 may be conventionally constructed to be removably received by the housing 3 at the open end 11 by using conventional methods such as a snap-fit design. Also, the closed end 13 of the housing 3 may be conventionally constructed to removably receive the cap 7 when the highlighter 1 is operative.
The highlighter 1 may further comprise a nib guide 35 on the housing 3. The nib guide 35 may be a color strip, preferably the same color as the highlighter ink, printed on the housing 3. The nib guide 35 may be disposed on the nib's longitudinal plane 9, behind the nib 5, before the cut-out section 15. The nib guide 35 may have a width equals to the width of the nib 5, thus resembling the highlighting path of the nib 5. The nib guide 35 may allow a user to use it as a guidance for highlighting path when the highlighter 1 is operative. The nib guide 35 may be made in different variation such as an indent or a bump on the housing's surface, or any other preferred masking as appreciated by one skilled in the art, for the purpose of providing guidance of the highlighting path of the nib 5,
The highlighter 1 is placed over the paper 50 having text written thereon. The cut-out section (not labeled) allows the user to see the text within the see-through area (not labeled).
