Nasdaq files patent on Digital Assets

I see Nasdaq filed a patent in May 2017 on digital assets and secure voting etc.  This is identical to the work done by Counterparty and Bytestamp.  It also overlaps what was done with Apertus.  They show no code, only concepts.  Counterparty, Bytestamp and Apertus have all shown real code with real use cases.

Here is an article:   https://cointelegraph.com/news/nasdaq-files-patent-for-blockchain-based-asset-ownership-data-storage-system

And here is the patent: http://appft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.html&r=1&p=1&f=G&l=50&d=PG01&S1=20170330174.PGNR.&OS=dn/20170330174&RS=DN/20170330174

I honestly think this patent should be opposed.  This is an attempt to control work that other people have done and which is already in the public domain.
