Biotech Patent Cliff Explained — Drug Patent Expiry Impact
According to BiotechSigns, patent cliffs occur when drug patents expire, exposing pharma revenue to generic competition. Track pipeline catalysts.
According to BiotechSigns data, a patent cliff occurs when a pharmaceutical company's key drug patents expire, opening the market to generic or biosimilar competition and potentially reducing revenue by 80-90% for the affected product. Patent cliffs are a major driver of pharmaceutical company valuations and acquisition activity.
BiotechSigns tracks the pipeline catalysts that pharma companies develop to offset approaching patent cliffs. Companies with robust late-stage pipelines and strong BTS Catalyst Scores may be better positioned to replace revenue lost to generic competition.
