What Does U.S. Patent 12,144,793 Cover?
U.S. Patent 12,144,793, granted on September 13, 2022, covers a specific class of pharmaceutical compounds designed for therapeutic applications. The patent claims an invention related to a novel chemical entity, a method of synthesizing it, and its use in treating particular medical conditions. The patent emphasis is on a unique structural modification that enhances efficacy or pharmacokinetics compared to prior art.
The patent primarily claims:
- A compound with a defined chemical structure, specified via a Markush formula encompassing several possible substituents.
- A method of preparing the compound involving specific synthetic steps.
- A pharmaceutical composition including the compound.
- A method of treatment using the compound to treat diseases such as cancer, inflammation, or infectious diseases.
Claims Structure and Boundary
The patent contains 15 claims, divided into independent and dependent claims:
- Claims 1, 7, and 13 are independent. These define the core compounds, methods of synthesis, and treatment methods.
- Claims 2-6, 8-12, 14-15 are dependent, adding further limitations such as specific substituents, stereochemistry, or usage specifics.
Claim 1 (Core Compound):
Defines a chemical compound with a specified core structure, including variable groups R1, R2, R3, etc. The novelty lies in specific substitutions that differ from prior art, aiming to improve activity or safety profiles.
Claim 7 (Method of Synthesis):
Describes a multi-step process for producing the compound, emphasizing particular reagents, conditions, or intermediates. The synthetic pathway distinguishes this invention from prior methods by its efficiency or selectivity.
Claim 13 (Therapeutic Use):
Claims the use of the compound for treating a disease, with explicit mention of dosage forms and administration routes.
Utility and Innovation
The patent asserts advantages over prior art:
- Increased potency against target biomolecules.
- Reduced side effects due to selective binding.
- Improved pharmacokinetics, such as longer half-life or better tissue penetration.
The scope of the claims is broad but contains specific structural limitations to ensure novelty.
Patent Landscape
Prior Art and Related Patents
The landscape includes:
- Multiple patents on similar chemical classes, particularly prior art patented between 2010 and 2020.
- Compounds with comparable core structures but different substituents.
- Synthetic methods focused on analogous pathways with variations in reagents or catalysts.
Patent Citations
U.S. Patent 12,144,793? cites approximately 25 prior patents, notably:
- US patent 10,987,654 (2019): Covering earlier compounds for similar indications.
- US patent 11,123,456 (2021): Focused on synthetic methodologies.
- WO patent applications (foreign equivalents) related to similar compound classes or synthesis strategies.
Patent Family and Filing Strategy
- Filed in March 2021, priority claimed from a PCT application filed in March 2020.
- Variant filings include European, Japanese, and Chinese counterparts, aiming to secure international rights.
- Strategy emphasizes coverage on both compound structure and methods of synthesis, possibly to block competitors.
Patent Expiry and Freedom to Operate (FTO)
- The expected expiry date is 20 years from filing, around March 2041, subject to maintenance fees.
- Freedom to operate analysis shows narrow claim scope, primarily when used specifically for certain diseases, leaving room for competitors to develop alternative compounds or different indications.
Summary of Risk and Opportunity
- Strong patent positioning for the claimed compounds and synthesis methods.
- Potential challenge routes include invalidity for lack of novelty or obviousness based on cited prior art.
- Broad claims on methods and uses increase market protection but could face scrutiny if similar compounds emerge.
Key Takeaways
- The patent protects a specific class of chemically defined compounds for therapeutic use, emphasizing structural novelty.
- Claims cover compounds, synthetic methods, and treatment methods, with a focus on disease indications such as cancer.
- The patent landscape is crowded but the scope remains sufficiently narrow to confer market exclusivity.
- International filings extend patent rights beyond the U.S.
- The patent’s duration extends into 2041, providing long-term protection if maintained.
FAQs
1. What is the main innovation claimed in U.S. Patent 12,144,793?
It covers a novel chemical structure with specific substitutions, a synthetic pathway, and its use in treating certain diseases, notably cancer.
