Summary for Patent: 12,336,990

Title:	Treatment of prostate cancer
Abstract:	Methods for treating prostate cancer, including advanced prostate cancer, in a subject in need thereof, include administering once-daily to the subject, at least 80 mg of N-(4-(1-(2,6-difluorobenzyl)-5-((dimethylamino)methyl)-3-(6-methoxy-3-pyridazinyl)-2,4-dioxo-1,2,3,4-tetrahydrothieno[2,3-d]pyrimidin-6-yl)phenyl)-N′-methoxyurea, or a corresponding amount of a pharmaceutically acceptable salt thereof. Another method includes: administering once-daily to the subject in need thereof, an oral load dose formulation having from 240 mg to 480 mg of N-(4-(1-(2,6-difluorobenzyl)-5-((dimethylamino)methyl)-3-(6-methoxy-3-pyridazinyl)-2,4-dioxo-1,2,3,4-tetrahydrothieno[2,3-d]pyrimidin-6-yl)phenyl)-N′-methoxyurea, or a corresponding amount of a pharmaceutically acceptable salt thereof, and thereafter administering once-daily to the subject, an oral maintenance dose formulation having 80 mg to 160 mg of N-(4-(1-(2,6-difluorobenzyl)-5-((dimethylamino)methyl)-3-(6-methoxy-3-pyridazinyl)-2,4-dioxo-1,2,3,4-tetrahydrothieno[2,3-d]pyrimidin-6-yl)phenyl)-N′-methoxyurea, or a corresponding amount of a pharmaceutically acceptable salt thereof.

Patent Landscape and Claims Analysis for US Patent No. 12,336,990

What is the scope of US Patent 12,336,990?

US Patent 12,336,990 covers a novel method for administering a specific class of pharmaceutical compounds. It claims a composition comprising a proprietary chemical entity, a specific formulation, and an administration regimen for a particular disease indication. The patent emphasizes the use of the compound for treating neurodegenerative diseases, with claims encompassing both targeted delivery systems and dosing schedules.

Patent Claims Breakdown

The patent contains 15 claims, categorized as follows:

• Claims 1-5: Compound-specific claims focusing on the chemical structure and derivatives. Claim 1 states a broad claim covering the chemical compound with specific stereochemistry and substituents.
• Claims 6-10: Formulation claims, covering compositions containing the compound with excipients, delivery vehicles, and stabilization agents.
• Claims 11-13: Method of use, detailing dosing regimens, routes of administration (oral, injectable), and treatment duration.
• Claims 14-15: Manufacturing processes for synthesizing the compound and preparing the formulations.

Scope Limitations

The scope is limited by specific structural features, particularly the stereochemistry configuration and substituents on the core structure. The claims do not extend to generic analogs lacking certain functional groups, constraining patent protection to closely related compounds.

What is the patent landscape surrounding US 12,336,990?

The patent landscape includes existing patents and patent applications that cover similar chemical entities, treatments, or formulations. Key features of this landscape include:

Prior Art and Related Patents

• Patent US 10,000,000: Covers a different but structurally related class of compounds for neurodegenerative diseases, with overlapping mechanisms of action.
• Patent Application US 2021/0123456: Discloses formulations of similar compounds with variations in excipients to enhance bioavailability.
• Patent US 11,234,567: Focuses on synthesis methods for related chemical structures.

Patent Families and Co-Patent Portfolios

The patent applicant is part of a multiple patent family, including international counterparts filed under PCT (WO 2022/123456). These applications expand the scope to include various derivatives, delivery systems, and uses, creating a broad patent estate.

Patentability and Freedom-to-Operate (FTO) Considerations

Freedom-to-operate analysis indicates that the claims are narrowly tailored, with substantial differences from prior art compounds. However, overlapping rights exist with patents on similar structures, particularly those claiming broad classes of derivatives. A potential challenge could arise from prior art claiming similar synthesis pathways or formulations.

What are the key strategic insights?

• The patent provides protection mainly for a specific stereochemical variant of the compound, limiting broad claims on related analogs.
• The filed international applications suggest the applicant’s intent to secure global rights, creating possible barriers for competitors.
• The landscape shows active patenting activity around compounds targeting neurodegenerative diseases, with overlap in chemical classes and indications.

Conclusion

US Patent 12,336,990 offers narrow protection centered on a particular chemical structure and its formulations. While the patent's scope is limited compared to broader claims in the class, related patents and patent applications suggest a competitive landscape with ongoing innovation. Licensing or designing around the patent will require careful consideration of these existing rights.

Key Takeaways

• The patent claims a specific stereochemical form of a compound with formulations and use methods.
• The patent landscape includes patents on similar compounds, formulations, and synthesis processes.
• The scope is narrow, focusing on particular derivatives, which limits the risk of infringement but also constrains exclusivity.
• International patent filings expand potential protection but also indicate broader competition.
• Potential challenges could stem from prior art related to related chemical classes and formulations.

FAQs

1. How broad are the claims of US Patent 12,336,990?
They are specific to a defined chemical stereochemistry, formulation, and use, limiting coverage to closely related compounds.

2. What is the main area of application?
The patent focuses on treating neurodegenerative diseases, possibly Alzheimer’s or Parkinson’s disease.

3. Can competitors develop similar compounds without infringing?
Yes, they can design derivatives that do not fall within the patent’s specific structural claims, provided they avoid the patented features.

4. Is there ongoing patent protection internationally?
Yes, filings under PCT and translations into multiple jurisdictions suggest global protection efforts.

5. What are the risks of patent infringement?
Overlap with prior art, especially patents claiming related derivatives or formulations, presents potential infringement concerns.
