Annovis Bio Files Patent for New Composition of Matter for Buntanetap

[Farooqji]

This patent covers novel crystalline forms of buntanetap and their use for treating and/or preventing various neurodegenerative conditions. Crystalline forms offer significant advantages over less structured forms, including better solubility and stability. The most stable crystal form of buntanetap (CAS# 3032752-92-1) has been selected as the new lead compound for animal bridge studies and for developing a manufacturing process. The bridge studies were submitted to the FDA and will be discussed in July. The goal is to continue development of our drug and file the NDA with the new crystal form.

seems that they are insisting on a failure

AI says:

Patenting a new crystalline form of a drug can indeed extend patent protections. Here's how it works:

1. **Novelty and Non-Obviousness**:

- To obtain a patent, an invention must be novel (not previously disclosed) and non-obvious (not an obvious modification of existing knowledge).

- A new crystalline form of a drug can meet these criteria if it represents a significant improvement over existing forms.

2. **Patent Scope**:

- When a new crystalline form is patented, the patent covers the specific structure of that form.

- The patent holder gains exclusive rights to make, use, and sell the drug in that crystalline form.

3. **Extended Monopoly Period**:

- Patents typically last for 20 years from the filing date.

- By patenting a new crystalline form, the drug manufacturer can extend its monopoly period beyond the original patent covering the active ingredient.

- This exclusivity allows the company to recoup research and development costs and generate profits.

4. **Market Exclusivity**:

- Even if the original patent expires, competitors cannot produce the same drug in the patented crystalline form during the extended exclusivity period.

- This helps maintain market dominance and revenue.

5. **Strategic Advantage**:

- Patenting different forms (e.g., salts, polymorphs, hydrates) provides a strategic advantage.

- It allows the company to block generic versions and maintain control over the drug's market presence.

Remember that patent law can be complex, and specific cases may vary. Consult legal experts for precise advice related to drug patents. 😊🔬📜
