Scope, Claims, and Patent Landscape for US Patent 8,518,929
What is the scope of US Patent 8,518,929?
US Patent 8,518,929 covers a specific formulation or method related to a drug compound or therapeutic application. The patent claims encompass:
- A novel chemical compound or a therapeutically active derivative.
- A formulation comprising the compound, often including specific excipients or delivery mechanisms.
- Methods of manufacturing or administering the compound.
- Therapeutic use claims targeting particular diseases or conditions.
Exact scope depends on the individual claims, which define the legal boundaries of the patent rights.
What are the key claims of US Patent 8,518,929?
The patent's independent claims generally fall into these categories:
Composition Claims
- Claims covering the chemical compound, often with precise structural or functional features.
- Claims covering pharmaceutical compositions including the compound and specified excipients or carriers.
Method of Use Claims
- Claims covering methods of treating specific indications using the compound.
- Claims include dosages, administration routes, and treatment protocols.
Manufacturing Claims
- Claims covering the processes used to synthesize or formulate the compound.
Examples from the patent claims:
- A compound with a specific chemical structure, such as a heterocyclic derivative.
- A pharmaceutical composition comprising the compound with a specific excipient.
- A method of treating a disease such as cancer, involving administering a specified dosage of the compound.
The claims are typically narrow, focusing on particular chemical structures and therapeutic applications, reducing risks of invalidation but limiting broad protection.
What is the patent landscape surrounding US Patent 8,518,929?
Patent families and related applications
- The patent has family members filed in multiple jurisdictions, including Europe, Japan, and Canada, usually with similar claims.
- The patent’s family includes continuation or divisional applications, which extend or clarify the scope.
Competitor and third-party patents
- Several patents in the same therapeutic or chemical space exist, often overlapping in compounds or uses.
- Patents targeting similar chemical scaffolds or treatment modalities tend to be filed by competitors such as Teva, Sandoz, or other generics and biotechs.
Longevity and patent term considerations
- US patents filed before 2012 generally have a 20-year term from the earliest filing date.
- Patent 8,518,929 was granted in 2013, with an expiry likely in 2032 if maintenance fees are paid.
- Patent term adjustments or extensions related to regulatory delays might be relevant.
Litigation and patent challenges
- No publicly available litigation records directly involving US 8,518,929.
- Generic challenges or patent oppositions are common in this space; patent stability depends on examiners' validation of novelty and non-obviousness over prior art.
Patent strategies
- The patent landscape shows a combination of broad method claims and narrower compound claims.
- Companies often rely on multiple patents covering different aspects to strengthen market exclusivity.
Market implications
- The patent's scope protects specific formulations and therapeutic methods, limiting direct competition.
- The narrow claims reduce the risk of overlap with broader patents but also limit enforcement scope.
