Re: Coinbase Patents

To my understanding a pledge such as the one by Blockstream is legally binding.

Correct. And in addition to the pledge we have the DPL and MIPA which are two additional distinctive ways that users get protective coverage. These provide additional assurance in case of any limitation or issue with the pledge (and vice versa). (MIPA is kind of narrow: it says the inventors are also able to grant licenses for defensive use)

I saw some of you are against AsicBoost's patent. Will u support it if they make a similar pledge like BlockStream ?

^^^ Warning!
This user is simply a shill account for the
'cloud mining' ponzi scam he promotes in
his signature.

Nothing that is open-source can then be patented as it is already public knowledge. So if they are developing entirely new tech for commercial gain then it is up to them if they want to monetise their IP.
