Company patents

Zoetis Services LLC

Zoetis Services LLC's patent strategy is heavily concentrated in pharmaceutical innovation, with Pharmaceutical Preparations (63.6% of portfolio) and Therapeutic Activity (Pharma) (37.9% of portfolio) being core areas, both experiencing significant growth in 2024 (172.7% and 100.0% YoY, respectively), although patent filings in these categories have seen a sharp decline so far in 2026. A surprising emerging focus is Heterocyclic Compounds (Pharma), which saw an 800.0% YoY increase in 2025, indicating a strategic pivot despite its smaller share (12.1%) of the overall portfolio.
