Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 225 words
A writing instrument which comprises: (a) an elongated casing with a first portion and an oppositely disposed second portion; (b) a writing tip at remote end of the first portion of said casing; (c) a slide cap having an opening at a distal end thereof being telescopically received over the first portion of the casing and moveable along said casing between (1) a retracted position in which said slide cap overlies the second portion, thus leaving said writing tip exposed and (2) an extended position in which said slide cap covers said writing tip, thus protecting said writing tip; (d) means for releasably retaining said slide cap in each of the retracted and extended positions; (e) a clip affixed to said slide cap for mounting onto a web of cloth material of the user; (f) a cover movably mounted on said cap adjacent said opening when said cap is moved to said retracted position and (2) a closed position in which said cover conceals said opening when said slide cap is in said extended position; and (g) means external of the cap on the clip for manually moving said cover to the open and closed position, wherein the cover is pivotally mounted on the clip and includes pivotal arms for movement from an open position spaced externally from said distal end to a closed position.
Claim 2
Dependent Claim 225 words
A writing instrument which comprises: (a) an elongated casing with a first portion and an oppositely disposed second portion; (b) a writing tip at remote end of the first portion of said casing; (c) a slide cap having an opening at a distal end thereof being telescopically received over the first portion of the casing and moveable along said casing between (1) a retracted position in which said slide cap overlies the second portion, thus leaving said writing tip exposed and (2) an extended position in which said slide cap covers said writing tip, thus protecting said writing tip; (d) means for releasably retaining said slide cap in each of the retracted and extended positions; (e) a clip affixed to said slide cap for mounting onto a web of cloth material of the user; (f) a cover movably mounted on said cap adjacent said opening when said cap is moved to said retracted position and (2) a closed position in which said cover conceals said opening when said slide cap is in said extended position; and (g) means external of the cap on the clip for manually moving said cover to the open and closed position, wherein the cover is pivotally mounted on the clip and includes pivotal arms for movement from an open position spaced externally from said distal end to a closed position.
Claim 3
Dependent Claim 299 words
A writing instrument which comprises an elongated casing with a first portion and an oppositely disposed second portion; (b) a writing tip at a remote end of the first portion of said casing; (c) a slide cap having an opening at a distal end thereof being telescopically received over the first portion of the casing and moveable along said casing between (1) a retracted position in which said slide cap overlies the second portion thus leaving said writing tip exposed and (2) an extended position in which said slide cap covers said writing tip, thus protecting said writing tip; (d) means for releaseably retaining said slide cap in each of the retracted and extended positions; (e) a clip affixed to said slide cap for mounting onto a web of cloth material of the user; (f) a cover movably mounted on said cap adjacent said opening when said cap is moved to said retracted position and a closed position in which said cover conceals said opening when said slide cap is in said extended position; and (g) means external of the cap on the clip for manually moving said cover to the open and closed positions, wherein said retaining means includes: (h) two spaced apart external protrusions, one of said protrusions on the first portion and other of said protrusions on the second portion of said casing; (i) said slide cap having an internal indentation receivable on said respective protrusions and wherein; (j) said cover is slideably mounted on said clip and slides into a groove at said distal end of said clip, further comprising a flange ring secured to remote end of the second portion of said casing to prevent insertion of said clip onto said web of cloth material when said slide cap is in the retracted position.
Claim 4
Dependent Claim 299 words
A writing instrument which comprises an elongated casing with a first portion and an oppositely disposed second portion; (b) a writing tip at a remote end of the first portion of said casing; (c) a slide cap having an opening at a distal end thereof being telescopically received over the first portion of the casing and moveable along said casing between (1) a retracted position in which said slide cap overlies the second portion thus leaving said writing tip exposed and (2) an extended position in which said slide cap covers said writing tip, thus protecting said writing tip; (d) means for releaseably retaining said slide cap in each of the retracted and extended positions; (e) a clip affixed to said slide cap for mounting onto a web of cloth material of the user; (f) a cover movably mounted on said cap adjacent said opening when said cap is moved to said retracted position and a closed position in which said cover conceals said opening when said slide cap is in said extended position; and (g) means external of the cap on the clip for manually moving said cover to the open and closed positions, wherein said retaining means includes: (h) two spaced apart external protrusions, one of said protrusions on the first portion and other of said protrusions on the second portion of said casing; (i) said slide cap having an internal indentation receivable on said respective protrusions and wherein; (j) said cover is slideably mounted on said clip and slides into a groove at said distal end of said clip, further comprising a flange ring secured to remote end of the second portion of said casing to prevent insertion of said clip onto said web of cloth material when said slide cap is in the retracted position.
