And on a different note about bolts, could you put a spring in the front of the bolt so that it moves moves backwards faster after being shot so less air is used when recocking the gun? I'm not sure if this has been attempted yet, but I had the thought today and don't know enough about how to eNMey works yet to know if it will do anything.
No idea about the spring idea. Wouldn't a spring mean more pressure needed to shoot. Thus, less efficient?

That's what I was thinking too. But I've seen other markers use springs in similar fashions. Granted, every marker has its on bolt system and air travel, I just thought it'd be interesting to see if the same idea that works in other markers holds true with the eNMey too. Would a spring in the front and back just cancel each other out, even if they were each a different stiffness?

And if you decreased the volume in the back would that compensate for the higher pressure? Lots of poppet valve markers use higher pressures and lower volumes to achieve higher efficiency than spools, right?

This is all too much thinking for me. Why can't Lurker just make something...

From my understanding there's a patent issue with Dye that would require them to pay Dye a licensing fee to sell them Possibly that fee isn't worth the cost to them, although I've heard some of Dye's IP might not be an issue anymore because they didn't pay the maintenance fee on the patents. Not sure if it applies to this though.

I talked to Tim at Techt and they deffinently can not produce the l6 anymore due to the patent held by Dye. Technically they can t even sell they're stock. Lol he said they run a field and have eNMey s as rentals and put em all in they re rentals. Anyway e-paintball has some L6 bolts for sale but Tim says they are probably a Chinese knock off. But hey whatever works. Anyway you can always mod. Vibe/envy/extcy bolt and machine an oring in the tail. I did it and drilled down the shaft like the L6 and it created a hole I could put a tail stock in and machine the oring groove with great consistency. And drilling down the shaft made the bolt lighter at the same time. I also machined the shaft where the dump point begins and made it lighter then the L6

Well lighter than what is advertised. I think It actually runs a couple grams lighter than advertised. If that's the case than my modded bolt is L6 comparable.

Paintball does not have L6 bolts. Even though they still advertise them.

Techt may not be aware that the patent expired.

Quote:
The DYE patent only covered specific features of spool operation - the most important aspect of which is using the bolt as a spool valve shutoff for the incoming air to isolate the dump chamber. The stock Ions didn't/don't do this, and the Shocker didn't do this until the HE bolt. Lots of aftermarket Ion bolts do this, and some upgrade factory bolts as well I believe. I believe, however, that the enmey will have this feature.

But, the DYE patent may no longer matter (making their prior arrangements also not matter, regardless of which business made the agreement). When searching for some patent related information the other day, I found a part of the USPTO site that lets you check any patent that has not expired due to age, and it will give you its status due to payment or non-payment (abandonment). According to that, 5,613,483 - the patent for the Omega/Matrix - expired in 2009 due to non-payment. I'm trying to figure out if there were any others that are valid that may have been a direct result of that patent, but if not it may no longer be an issue.

https://ramps.uspto.gov/eram/patentMaintFees.do
patent is 5613483
application number is 08555625 (gotten from the cover sheet of the issued patent - the 08 is not shown on this and comes from a chart on the link above).

Select "get bibliographic data"

"Expired, No 12th year fee paid by: 03/25/2009"

Works on any patent that hasn't auto-expired due to age.

USPTO Assignments on the Web

That will let you check who the current holder of a patent is, as well as the previous holders. DYE acquired the Omega/Matrix patent on May 27, 2003.

A maintenance fee payment can be timely made using the certificate of mailing or transmission procedure set forth in 37 CFR 1.8.
It seems there was some confusion in the transfer from the Canucks to Mr. Youngblood as the address for fees is still Oakville.

It would be in Techt's best interest to simply try and start selling the bolts. There's definitely a market. Put them up for sale--see if there's a letter from Dye. If yes, have it investigated through their lawyer or claim ignorance due to them thinking the patent was expired and take them off the market again. If they already have the bolts, there's really nothing to invest to trying this out.

If they're free and clear on the Ion, they can start making bolts for other spoolies that use the patent.

Or am I missing something here?
