Cold Spring Diagnostics

Cold Spring Diagnostics was a private U.S. healthcare company focused on molecular imaging approaches for identifying internal bleeding sites. Publicly visible evidence for the company is primarily tied to patent filings covering diagnostic methods that use clotting-related proteins, including fibrinogen-based approaches, linked to imaging agents detectable by fluorescent, PET, CT, or MRI methods. The company appears to have operated as an early-stage diagnostic/imaging venture rather than a therapeutics developer, with no evidence of commercialized products or an active clinical pipeline. Available records also indicate that Marc Filerman co-founded the company. Based on the limited recent footprint and lack of an active operating presence, it appears to be inactive.
