Quote from: Bitmine

Precisely, we are the owner of the IP inside the A1 chip

Quote from: Innosilicon

Innosilicon is proudly announcing that BitMine AG, a leading bitcoin mining system supplier, has licensed its ultra low power Hash IP Core for production

Bitmine says they own it. Innosilicon says Bitmine licensed it. Innosilicon isn't a brand new company. Bitmine is. I'd give the benefit of the doubt to Innosilicon.

Your miner is not from us and it is not the same as JTminer. Basically, the JTminer with smaller size is much stable and can do overclock. Please ask the suggestion from who you bought it if you want to do overclock. We are not responsible for what is not from us. Thanks.

Bitmine and Innosilicon worked together to produce the chips, so both of them have rights to produce/resell the chips.

I´m a little bit confused.... how many representatives for the JingTian miner is on bitcointalk?

(Seeksilence, skyfromwell and JT miner)

Yes. Those are from my company.

Alright, thanks for making that official

How about the pictures from the demonstration you held, will they be uploaded soon?

I will let someone put more pictures here.

I need to pick up my system now. LOL. I will try to do a good over clock then report to your guys.

Im looking forward to the OC guide- Do you think a EVGA 1300W g2 is enough to overclock, or should we get something higher?

Bob, it is not problem of the power. It is the problem with the system you got. LOL.

Don't over-clock it. The one who sell to you using cheap components in the board, so over-clock is NOT going to work there.

Please stop telling me what I do or dont have. These are not knockoffs- I have been running them OC for weeks now, and they also look identical to all the other units me and my assosiates purchased. Same design, PCBs chips, etc as the legitimate ones. Oh, and and the PCBs + parts numbers match up with the ones your selling directly.

JT, it seems like a Chinese manufacturer has ripped off your designs and is selling them as their own. Wait.. where have I seen that before Grin

Libel? It sounds like you have a statement from Innosillicon contradicting bitmine's claims. Please do share.

What is actually Innosilicon's current position on this matter is this, and I quote from their web :
"Innosilicon Announce its 28nm Bitcoin Mining IP core in Production
Innosilicon is proudly announcing that BitMine AG, a leading bitcoin mining system supplier, has licensed its ultra low power Hash IP Core for production at GF 28nm HPP process. This IP is designed from scratch using patent pending, customized VLSI computational Marco cells developed to squeeze the best possible power efficiency in 28nm. Its ultra high power efficiency and thermal reliability allows BitMine AG to pack just the right amount of innovative hash horse power inside a A1 CoinCraft ASIC. The availability of this 28nm hardened IP core instantly raised the bar in a crowded 28nm bitcoin mining ASIC field."

This might mean, that :

a) Bitmine.ch has patented (patent pending), their HPP proces (sublicenced from GF and forked), based on their Bitcoin Mining IP core
b) Innosilicon has given permission to Bitmine.ch to use their ultra-low-power Hash IP core for 28 nm DIE for chips produced by Innosilicon for Bitmine, and probably given only to Bitmine and nobody else.
c) Who did customized VLSI computational Marco cell (power train in 28 nm) - Synapse, Verisilicon, Innosilicon, Bitmine or GlobalFoundries is not known to me at this point. Also not known if this customized VLSI method is patented by someone.

Even though somebody could obtain licence from Innosilicon for power layer, other layers are still not Innosilicon property, so without Bitmine's sublicence on final design, full tapeout of cloned chips is not [legally] possible.

It has nothing to do with BRANDNAME - "COINCRAFT A1" as s BRAND, but with TOPOGRAPHIC DESIGN OF INTEGRATED CIRCUITS, which is SEPARATE LEVEL OF INTELECTUAL PROPERTY PROTECTION FROM BRAND(NAME) PROTECTION, patent pending according to Madrid Convention of the World Intelectual property organisation. Patents are accesible from WIPO portal, and they are many, and non of which are the property JingTian.

There's more than one IP inside the chip.

All stakeholders must unanimously agree on the conditions of use. There is no disagreement between stakeholders regarding bitmine's right to sell the A1 chip. There is disagreement between stakeholders regarding Innosilicon's right to sell the A1 chip.

Now these two love birds may work it out in the end with Innosilicon also obtaining the rights to sell the chip. But as things stand, Innosilicon does not have the right to sell the chip and therefore all Chinese miners based on the 28nm A1 chips obtained from Innosilicon are the product of IP theft.
