Re: Spiral fluting is NOT allowed by barrel manufacturers

I wouldn't think that something like spiral fluting could be trademarked but that's just me. I wonder if the twist and depth of the fluting is also trademarked? Seems like this would be easy beat in court.

I lke my flutes straight, the bullets fly faster and straighter with straight flutes

    Re: Spiral fluting is NOT allowed by barrel manufacturers

    To bad ER Shaws' barrels of of such poor quality they have to sell them at Wal Mart prices to move them. I have customers buy them from various suppliers and bring them to me to have them fitted and chambered. Time and time again I turn them away as I will not install any barrel that is not guarenteed. Take a look inside the bore of one their barrels and observe the finish bore reamer rings inside the bore. Im Amazed thought at the "patent" on the spiral fluting process. New one on me or sure. Guess Im patent infringing when I use a screw driver to loosen a screw on any number of firearms in the process of repairing it. I spiral flute barrels as well as bolts. I charge for bolts and accept donations for spiral fluting barrels. I do make sure I dont use the same shape or size cutter as ER , and my twist ratio is different. I even use a different finishing process. Maybe I can even check into them "infringing" on my process as well as my constitutional rights to care for and feed my family. Second rate products protected by smoke screen patents. Sounds like the current administration in office this tearm.

    Patents are founded on law. Law is what makes this country great. (Lawyers however are another matter.) Just buy an ER Shaw barrel if ya want all that spiral foolishness.

    Re: Spiral fluting is NOT allowed by barrel manufacturers

    I am the holder of several patents and I can tell you it means almost nothing anymore !!!

    If an item is a really good one then someone just simply steals it and has it made in china
    by the millions and markets it . and if the heat gets to much they just discontinue the product
    after making millions.

    The only way a patent has any strength is against any American manufacture like a Winchester or
    a Remington and they would not be able to get away with doing spiral fluting with in the
    guide lines of the patent. But if they wanted to they could study the patent description and figure
    out away around it in most cases.

    The fact that a person has a patent does not mean that they though of it first just that they
    applied for it first and it was excepted.

    I had one patent stolen by a company that simply predated my design and submitted it and
    my application was denied.

    So I say lots of luck to Shaw. It will probably cost them money rather than make them money.

    Its like saying you can't file any notches in your pistol grips because I have the patent.

    If a barrel manufacture does not want to do it "No Problem" there are many good barrel
    makers and gunsmiths that will.

    Re: Spiral fluting is NOT allowed by barrel manufacturers

    JE is correct. China/India do not observe patent laws, you can have anything made you want there. Importing and selling into the US, though, is another story.

    Looks like a weak patent to me, without any proof that the spirals actually do anything novel. The thing you need to understand about patents is that you can FILE a patent on almost anything -- the gov't gives it a cursory look, but does NOT test any claims for validity.

    The strength of a patent is not vetted unless it goes to court. Therefore, any other manufacturer could decide that the claims in the patent are bunk, and start manufacturing/selling them. The patent holder would then be within their rights to sue. In court, however, they will have to PROVE the claims in their patent. If they do not, the patent will be VOIDED.

    The caveat here is that the person/company challenging the patent has to feel it is worth their time/money to fight it in court. My guess is that the market for spiraled fluting is pretty small, so even a weak unfounded patent will stand due to the financial disincentive to challenge it.

    Re: Spiral fluting is NOT allowed by barrel manufacturers

    Now Im no expert in this field, and if some one knows some one who is a patent lawer ask them to validate this , but my understanding is that so long as the product has no less than 14 points of difference to the patented product it is in the clear because it is deemed different to the original product.

    Should'nt be hard to do that different lenghts, depths, angle, twist rate,
    bla bla bloddy bla, the guy that invented the wheel or discovered fire should be around today!
