Company patents

Exelixis, Inc.

Exelixis, Inc.'s patent strategy is heavily concentrated in Heterocyclic Compounds, representing 71.2% of its portfolio, yet this core area has seen a significant decline of 81.2% so far in 2026. Surprisingly, despite a strong focus on Pharmaceutical Preparations (47.0% of portfolio) with an 85.7% growth in 2024, the company appears to be shifting away from foundational chemistry, as evidenced by the complete cessation of patenting in General Organic Chemistry Methods and Peptides & Proteins so far in 2026.
