Predictive Oncology (POAI) only acquired the Soluble and BioDtech subsidiaries of INVB: https://last10k.com/sec-filings/poai And the subsidiary sale only cleared debt owed by INVB to POAI: https://www.sec.gov/Archives/edgar/data/1446159/000117184320004138/f8k_060220.htm https://www.sec.gov/Archives/edgar/data/1446159/000117184320004138/exh_21.htm https://www.sec.gov/Archives/edgar/data/1446159/000117184320004138/exh_991.htm So the INVB patch-clamp business wasn't sold off or acquired. You can also always DM former employees of INVB on LinkedIn. Just saying.
