PATENT OVERVIEW
Proparacaine Hydrochloride's foundational patents have long expired. The original synthesis and primary use patents, typically lasting 20 years from filing, were established decades ago. Subsequent patent filings often focused on formulation improvements, specific delivery devices, or novel combinations.
WHAT ARE THE KEY PATENT EXPIRATIONS FOR PROPARACAINE HYDROCHLORIDE?
The primary patent protection for Proparacaine Hydrochloride has lapsed. The original compound patents, which would have covered its core chemical structure and its initial medical uses, expired in the late 20th century. For instance, patents related to the original synthesis and therapeutic claims generally expired between 1980 and 1995 [1].
Specific patent filings that may have offered extended protection typically relate to:
- Formulation Innovations: Patents for improved ophthalmic solutions, such as those enhancing stability, reducing stinging, or altering viscosity. These patents generally have expiration dates ranging from the early 2000s to the late 2010s.
