Paintball Gun Technology - Search for prior art

  • This question relates (specifically) to paintball gun technology and (generally) to pneumatically launched projectiles. I'm looking for a description of a paintball gun where all of the following are present: 1) A chamber which is "charged" or filled electronically (not by pumping) to preasure prior to firing of the gun. 2) Electrically releasing the gas from the above chamber, thus firing the projectile. Again, electrically not mechanically. 3) Electrically loading a projectile into a chamber. Again not mechanically but electrically. 4) The description or reference you find must have been published or printed or disclosed prior to January 16, 1996. You get the idea, not a mechanical or pump action paintball gun, but one that is fully and electrically automated. Some hints for you, I have already done a fairly extensive review of the patents in this area so I think your time is best spent in other areas such as, brochures, technical manuals, articles, webpages, etc...Also, if all of the above exist but it is not for a paintball gun, that may be close enough. Ask as many questions as you like, good luck and thank you.


  • This may help. This is a patent infringement case and the following claims are the ones I hope to invalidate with a reference, or references, before 1/16/1996. 1) An electronically controllable paintball gun comprising: a body; a firing chamber located within said body, the firing chamber configured to selectively receive compressed gas from a compressed gas source; a bolt for loading a paintball into the firing chamber during a loading operation; a valve configured to selectively allow the compressed gas from the compressed gas source to enter the firing chamber to launch the paintball during a firing operation; and an electrical circuit for controlling one or more of the operations of the paintball gun, wherein the electrical circuit is configured to control the loading operation of the paintball gun by permitting or causing a quantity of compressed gas to move the bolt to an open position. 2) A grip for a paintball gun, said grip comprising: a trigger-actuated switch; and an electrical circuit mounted within the grip in electrical communication with the switch, wherein the electrical circuit is configured to initiate a launching sequence of the paintball gun in response to a trigger pull, and wherein the electrical circuit is further configured to control a loading operation of the paintball gun by sending an electrical signal to a solenoid. 3) A method for pneumatically launching a projectile from an electrically controllable launching device having at least first and second interconnected chambers, comprising the following steps: A. electrically controlling the filling of said first chamber of said launching device with compressed gas having a selected pressure; B. electrically controlling the launching of said projectile from said second chamber by releasing said compressed gas from said first chamber into said second chamber; and C. electrically controlling the loading of a projectile into said second chamber.


  • Hello - Couple questions: A) What if the answer is, "this item doesn't exist?" Is this acceptable? B) Can you expound upon your last clarification? Where did you find that information? Thank you, jbf777-ga


  • Hi and thanks for taking this on. A) What if the answer is, "this item doesn't exist?" Is this acceptable? Sorry, I will need the reference or references showing that it did exist prior to 1/16/1996 to provide the award. B) Can you expound upon your last clarification? Where did you find that information? US Pat 5967133 (claim 15) US Pat 6474326 (claims 4, 7) Thank you,


  • Hello - Due to the nature of this sort of request, I don't think a researcher would be willing to do this if there is a possibility that "the item doesn't exist" might be an actual answer. I.e., prior art searching as a service is paid for services rendered, not for the outcome of the service. Unless, you are absolutely positive that somewhere there is a reference to this sort of item prior to 1/16/96. A researcher could conceivably spend days searching, and conclusively determine that there is no prior art, yet not be rewarded for his time. Does that make sense? jbf


  • My apologies for the way my last clarification was written; it could be read to sound derisive. The last sentence should read, "Does what I'm saying make sense?"
