The ValiMed G4 drug validation system helps healthcare providers ensure patient safety and control costs by reducing medication errors. The patented detection process identifies drug strengths and volume-by-weight in real-time, validating proper dose, diluents and concentration of high-risk compounded medications and treatment solutions. The G4 device will help healthcare facilities comply with Joint Commission compliance requirements and USP 797 guidelines for compounding sterile preparations (CSPs) and integrate with electronic medical record (EMR) platforms.

The G4 technology is not patented. The bold text is referring to the old, Valimed technology which was once patented- but not any more.

I believe that the "volume-by-weight" is referring to the G4.
