Absolutely zero drag. As far as finding him it's tough. Fucking Goldstein tried suing him for making a frit.
Goldsteins background is making laboratory glass fritts. Raybaby didn't really make a frit, he's built his career as an actual artist and eventually was asked to blow some pieces.
Well this frit is actually nothing like a dg, the frit itself is actually weaved and braded. There is no resistance at all resulting in no drag at all.
I'll ask about a site, he's local here in Florida so you see his stuff in high end head shops.
Sue him for making a frit?????? Goldstein did NOT invent fritted glass, or even using it for gas diffusion in water. Fritted glass has been used in laboratories for at least 15 years from my own experience (I worked at an EPA lab 15 years ago for a while and we had fritted glass all over the water and air quality labs; do a search for fritted on ebay and you pretty much only get lab glass). In IP law, we call that prior art, and it is supposed to invalidate the patent in question. The US Patent and Trademark Office missed a lot of prior art in the past 20 years due to understaffing. I work with one software vendor, for instance, that got a patent for an OUTLINE, and has successfully sued other software vendors for using outlines to organize data in their apps.
If DG has a patent, the USPTO should NOT have granted it. On the bright side, since the America Invents Act, it is a lot easier to challenge an already-granted patent, you can even do it anonymously (an ex parte re-evaluation). Of course the US Patent and Trademark office has an insane backlog of these, 25,000 pending last I checked, because of all the insane software patents granted in the recent past. Hopefully they'll get to the glass patents they shouldn't have granted soon, like the PHX honeycomb patent (another piece of decades-old lab tech).
NOTE: Why does this text editor hate Latin? Every time I type in a Latin legal or scientific term it changes it to some unrelated English gibberish. I don't even try with Hebrew or Greek anymore.
