@Tonza: someone or a group were taking profits or saw something shiny elsewhere and needed the funds quickly.
My thoughts too. Also to be made if one got in at the previous M/C. Before the last one.
Something Shiny. Yes there is always something Shiny, just a question of finding it.

I think we will see the big changes in share price mid 2021.

My understanding is applying to WIPO under the Patent Cooperation Treaty (“International Patent Application”), to protect and commercialise its graphene biosensor technology intellectual property (“IP”) is part of a process. Having made the application to WIPO it then makes it easier to apply for Patents to individual countries and regions. The time allowed for this is 18 months or less. Once this is done then agreements can be signed with Bio Tech companies to either licence or sell the intellectual property.

My thinking is first there is possibly a German Biotech company lined up that is now working with Archer.

Of course I could have totally misunderstood the process so do your own research and made incorrect assumptions about the German bio tech company.
