Mosaic ImmunoEngineering (formerly Patriot Scientific Corporation) is a biotechnology company focused on bridging immunology and engineering to develop immunotherapies to treat and prevent cancer and infectious diseases. It develops a platform based on Cowpea Mosaic Virus ("CPMV") which is non-infectious to humans but upon intra-tumoral administration elicits an innate immune response resulting in potent anti-tumor activity against the primary and distant tumor sites. The company also uses an immunomodulator platform technology to produce modular vaccines under its modular vaccine platform.
