Ask Patents is a question and answer site for people interested in improving and participating in the patent system. It's 100% free, no registration required.

This application is claiming everything that is involved in Bitcoin mining or any other cryptocurrency mining using Asic chips where the block chain is segmented and hashed by multiple parallel hash units and then recombined. I would like to make sure open source cryptocurrency is not patented.

I know there should be something out there that teaches how to speed up mining with the use of GPU or Asic chips that is before July 11th, 2012.

Any Help would be appreciated!

Quite a few references are made.

It would be great if you posted few actual links with title and short description. –  silpol Dec 15 '14 at 13:48

It appears the examiner in this case is already familiar with bitcoin mining--there is a rejection based on that (with specific examples) already in the image file wrapper for this application.


From the non-final OA issued 6/20/2014 (it is a screenshot) this can be accessed via the USPTO's Public PAIR database.
