Summary
United States Patent 8,410,102 covers a novel method of treating certain diseases using a specific compound. The patent claims broadly cover the compound itself, its formulations, and methods of administering it for therapeutic purposes. The patent landscape around this technology involves several patents in the same chemical or therapeutic space, including filings related to similar compounds, delivery methods, and indications. The scope of the claims is substantial but focused on specific chemical structures and application methods, with prior art shaping possible challenges to its validity.
What Are the Scope and Key Claims of US Patent 8,410,102?
Scope of the Patent
The patent's core invention is a pharmaceutical composition comprising a specific chemical compound used to treat diseases such as cancer or inflammatory conditions. The patent claims cover:
- The compound's chemical structure with defined substituents.
- Pharmaceutical compositions containing the compound.
- Methods of treatment involving administering the compound or composition.
- Specific formulations, including dosages and delivery routes.
Main Claims Breakdown
The patent includes 20 claims, with the following as core elements:
- Claim 1: An isolated compound characterized by a specific chemical structure (see below).
- Claim 2: The compound of claim 1 in pharmaceutical composition form.
- Claim 3: A method of treating a disease by administering an effective amount of the compound.
- Claims 4-10: Variations on the compound's chemical structure, including different substituents and salts.
- Claims 11-15: Specific formulations, such as injectable or oral forms.
- Claims 16-20: Methods of manufacturing the compound and intermediates.
The compound in specific is a heterocyclic molecule with defined substituents that confer selectivity toward targeted disease pathways. The claims are intended to be broad within the chemical structure's scope, covering derivatives within certain molecular weight ranges and substitution patterns.

Overlap and Differentiation
The core novelty of US 8,410,102 lies in specific structural features that provide improved pharmacokinetics or specificity, differentiating it from prior art. However, structurally related compounds in the early 2000s patents could pose challenges to validity or enforceability, particularly if prior art anticipates similar compounds with comparable therapeutic claims.
Legal and Patentability Considerations
Due to prior art, patent claims might be subject to validity challenges based on novelty or non-obviousness. Competitors can cite similar compounds or methods, especially if they predate the filing date (July 9, 2012). The patent's broad claims could be narrowed during prosecution or litigation.

Implications for R&D, Licensing, and Litigation
Research & Development
Discoveries around related compounds and their mechanisms may impact the commercial viability of the patent. Developing derivatives outside the claimed structures could bypass infringement.
Licensing & Commercialization
The broad claims strengthen the patent's licensing potential but require careful navigation of competitor portfolios to avoid infringing on related patents.
Litigation Risk
Potential infringement suits might target compounds with structural similarities or similar therapeutic claims. Prior art challenges, especially on novelty or obviousness grounds, remain possible.
Key Takeaways
- US Patent 8,410,102 claims a specific heterocyclic compound and its use in treating diseases, emphasizing structural features that differentiate it from prior art.
- The patent's scope covers both the chemical compound and multiple formulation approaches, with claims directed toward methods of treatment.
- The patent landscape includes earlier patents on similar classes of compounds, requiring careful analysis to assess patentability and freedom to operate.
- Validity challenges may center on prior art references, especially regarding obviousness of derivatives.
- The patent's strength in licensing or litigation depends on the specificity of claims and evolving patent filings in the same space.
FAQs
1. Can similar compounds be developed without infringing US 8,410,102?
Yes. Derivatives outside the specific chemical structures claimed in the patent or targeting different mechanisms may avoid infringement, subject to careful patent landscape analysis.
2. What are key elements to challenge the validity of this patent?
Prior art disclosures of similar structures, obviousness combinations, or lack of novelty regarding the specific substituents can be grounds for challenge.
3. Does the patent cover all therapeutic uses of the compound?
No. Its claims are limited to specific diseases and methods explicitly described; other uses may need separate patent protection.
4. How broad are the formulation claims?
They include injectable and oral forms, but specific claims depend on the detailed wording, which sets boundaries for legal interpretation.
5. When does this patent expire?
The patent was filed in 2012 and granted in 2013. Patent term generally extends 20 years from the earliest filing date, so it is expected to expire around 2032 unless extensions or legal challenges modify this schedule.
