Most Relevant Prior Art for US12370153B2:

The patent text for US12370153B2 explicitly references two U.S. Patents as prior art in the context of terminal sterilization of ketamine formulations: U.S. Pat. Nos. 5,439,643 and 8,617,467.

Here's a breakdown of these references:

1. U.S. Patent No. 5,439,643

   • Full Citation: U.S. Pat. No. 5,439,643. (No title or dates are provided in the patent text or search snippets, so these details cannot be accurately presented at this time. An in-depth search for this patent number would be required to extract this information fully).
   • Publication/Filing Date: Not explicitly provided in the current search results.
   • Brief Description: This patent is cited within US12370153B2 in the context of terminal sterilization methods for ketamine formulations in infusion bags, specifically mentioning steam sterilization, heat sterilization (like autoclaving), radiation, or chemical sterilization (e.g., ethylene oxide).
   • Potential Anticipated Claim(s) under 35 U.S.C. § 102: Given its citation for terminal sterilization methods, it could potentially anticipate aspects of claims related to the method of preparing the ketamine product. Specifically, claims 48, 49, 50, 51, 52, and 53, which detail the terminal sterilization steps (including autoclaving) in the preparation method, could be implicated.

2. U.S. Patent No. 8,617,467

   • Full Citation: U.S. Pat. No. 8,617,467. (No title or dates are provided in the patent text or search snippets, so these details cannot be accurately presented at this time. An in-depth search for this patent number would be required to extract this information fully).
   • Publication/Filing Date: Not explicitly provided in the current search results.
   • Brief Description: Similar to U.S. Pat. No. 5,439,643, this patent is cited in US12370153B2 for its relevance to various terminal sterilization techniques for ketamine formulations in infusion bags, including steam, heat (autoclave), radiation, or chemical sterilization.
   • Potential Anticipated Claim(s) under 35 U.S.C. § 102: Like U.S. Pat. No. 5,439,643, this patent could potentially anticipate claims 48, 49, 50, 51, 52, and 53, which cover the method of preparing the ketamine product through terminal sterilization.

Without access to the full text of US 5,439,643 and US 8,617,467, a more detailed analysis of their descriptions and a definitive determination of which specific claims of US12370153B2 they potentially anticipate under 35 U.S.C. § 102 is not possible.
