owned and controlled by one company
Owned and controlled by one person or company, so other people cannot freely use or copy it.
Patrón de uso:
proprietary [software/technology/information/system/formula]
Error frecuente:
Learners sometimes think 'proprietary' means 'high quality' or 'expensive'. It only means that something is owned and controlled by a person or company. Learners also confuse it with 'proprietor' (the owner) and 'proprietorial' (showing an attitude of ownership).
