Company patents

Xencor, Inc.

Xencor, Inc. demonstrates a highly concentrated patent strategy, with Peptides & Proteins accounting for a dominant 98.6% of its portfolio. While patenting in Pharmaceutical Preparations showed strong growth of +30.0% in 2024, the significant year-over-year declines across all categories so far in 2026, including a -75.0% drop in Therapeutic Activity (Pharma) and -62.8% in Peptides & Proteins, suggest a potential shift in patenting focus or a slowdown in new filings, though 2026 data is partial.
