My search was performed form the Copyright office website.
Not from the USPTO site.
In the charm bracelet example, I never said the charm or attachment could not covered by copyright/patent.
The beaded necklace reference is in regards to the pattern.
The pattern design can be copyrighted. Last time I checked, a pattern design falls into the area of copyright under 2 dimensional or 3 dimensional works of visual art. Not really a patent case.
Do you know how many pattern variations have been used for making beaded necklaces??? Too many to count.
The chances of someone coming up with a pattern that hasn't been done before is pretty slim.
And yes, I am fully aware of copyright without registration.
Personally I think it's a bad idea. If you want to assert a claim, file the form and pay the fee. It's not rocket science to fill out, but if your confused, hire a good attorney to do it for you.

My point, to get to it quickly, is that the vast majority of jewelry that is being created and sold are based on centuries old designs and techniques.
Ask anyone who has been in the jewelry business for more than 20 years and they will tell you the same thing.
In the eyes of a long time jeweler, it is a rare occasion that a truly unique piece of jewelry hits the market.
It's more like "Oh look, they added ruby instead of an emerald" (insert a touch of sarcasm in the tone). Yes, it's over simplification at its finest, but you get the point.
I'm currently in a situation where a designer is claiming the right to a variation of the dog tag. Without going into too many details, the designer is basing the claim on size, material and typeface.
The designer is under the illusion that nobody else can make anything using the same material of a "similar" size and stamped with words using a "similar" typeface.
The typeface used on both products is in the public domain and can be used for commercial purposes without permission.
The material is a precious metal.
The alleged offending piece is half the size of the other designers piece and uses a similar, yet different typeface.
The designer is claiming blanket protection for a common design.
The "dog tag" has been around for centuries and has existed in many shapes and sizes.
The complaining designer has been advised that she has no standing for the "dog tag" design.
The basic design has been in the public domain for over 200 years.
Or to be more basic, letters stamped into a metal oval.
Yes, it's been done before. No, you're not the first to do it either.
