Week 38, 2013 – A Different Kind of Patent Trolling

One of my many hobbies is collecting airsoft guns.  Given that I am exceedingly poor, I have taken great interest in making airsoft guns and accessories.  Electric guns are easy, everyone knows how they work.  Gas guns are…not so easy.  I mean, the general how is fairly easy to understand, but the mechanical details and the way valves and stuff go together…  So I did a lot of digging for information, and that’s when I stumbled upon a patent, as well as the whole ‘Google Patents’ sub-site.

Once I figured out how to search right, my brain’s knack for retaining seemingly pointless trivia whether I want it to or not came in very handy.  For instance, a lot of Taiwanese and Hong Kong airsoft company names are seldom given as anything other than acronyms… But the full names— which over the years I have occasionally come across —are what’s on the patent applications.

Examples: ICS = I Chih Shivan Enterprise Co., Ltd. and HFC =  Ho Feng Industry Co., Ltd.

And of course the Japanese companies like Western Arms have all sorts of patents.  And all these applications have mechanical drawings.  Not dimensioned or anything, but I get the idea of what’s going on.

Here’s some interesting patents:
In-Magazine Pressure Reduction Valve (For 12g CO2 cartridges)
12g CO2 Cartridge Gas Gun Magazine (HFC’s patent)
ICS’s design for 40mm BB shower grenades (Not as nice as Madbull’s!)
The Firing and Rotary Magazine Assembly for ICS’s Rotary Launcher
