The Promising Viral Threat to Bacterial Resistance: the Uncertain Patentability of Phage Therapeutics and the Necessity of Alternative Incentives

Bacteriophages, or "phages," are a category of highly adept and adaptable viruses that can infect and kill bacteria. With concerns over the burgeoning antibiotic-resistance crisis looming in recent years, scientists and policymakers have expressed a growing interest in developing novel treatments for bacterial infections that utilize bacteriophages. Because of the great expense associated with bringing a new drug to market, patents are usually considered the gold standard for incentivizing research and development in the pharmaceutical field. Absent such strong protection for a developer’s front end investment, pharmaceutical development remains financially risky and unattractive. Unfortunately, recent Supreme Court jurisprudence analyzing patentable subject matter under 35 U.S.C. subsection 101 has cast doubt on whether phage therapeutics would be eligible for strong patent protection. In order for the promise of phage therapeutics to become a reality, alternative protections or incentives are likely necessary. Such a framework would likely include trade secrecy, regulatory exclusivities, research support, alternative payment models, or some combination thereof.
