Company patents

Pfizer Inc.

Pfizer Inc's patent strategy is heavily concentrated in core pharmaceutical areas, with "Pharmaceutical Preparations" accounting for 72.0% of its portfolio, yet it's surprising to see a rapid decline in patenting across most categories in 2026 so far, including a -47.9% YoY drop in "Pharmaceutical Preparations" and a -64.6% YoY decline in "Heterocyclic Compounds (Pharma)", indicating a potential shift in focus or a temporary slowdown in new filings compared to previous years.
