Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 112 words
An electronic stun gun device comprising a case having first and second contact probes exposed on opposite ends of the top of said case, said contact probes separated by a first distance, a cavity extending through the top of said case and extending across a portion thereof between said pair of contact probes, first and second test gap probes extending into said cavity from opposite sides thereof and separated by a second distance, said second distance being smaller than said first distance, and a closure member secured on said case at the top thereof for preventing an object from entering said cavity by passing through a plane extending between said contact probes.
Claim 2
Dependent Claim 112 words
An electronic stun gun device comprising a case having first and second contact probes exposed on opposite ends of the top of said case, said contact probes separated by a first distance, a cavity extending through the top of said case and extending across a portion thereof between said pair of contact probes, first and second test gap probes extending into said cavity from opposite sides thereof and separated by a second distance, said second distance being smaller than said first distance, and a closure member secured on said case at the top thereof for preventing an object from entering said cavity by passing through a plane extending between said contact probes.
Claim 3
Dependent Claim 25 words
