Methods of Creating and Screening DNA-Encoded Libraries

X-Chem, Inc. received USPTO Patent US12606817B2 for methods of identifying compounds that bind to biological targets using DNA-encoded libraries. The patented methods involve synthesizing libraries where compounds contain functional moieties with diversity positions, operatively linked to initiator oligonucleotides that identify compound structures. This is a standard biotech patent grant strengthening X-Chem's intellectual property position in DNA-encoded library technology.

Competitors developing DNA-encoded library screening methods should conduct freedom-to-operate analyses to assess potential infringement exposure. Pharmaceutical and biotechnology companies utilizing these techniques may need to evaluate licensing requirements or design-around strategies for drug discovery programs leveraging similar approaches.
