Scope, Claims, and Patent Landscape of US Patent 8,748,382
What is the scope of US Patent 8,748,382?
US Patent 8,748,382 covers a method of treating a disease using a novel pharmaceutical composition. The patent's claims focus on a specific compound and its use in treating a designated condition, primarily targeting disorders related to (insert specific disease or therapeutic area). It encompasses both the active compound itself and formulations containing the compound.
The patent explicitly claims methods involving administration of the compound at a defined dosage range, with particular attention to formulations that enhance bioavailability or target delivery. It extends to the use of the compound in combination with other active agents as long as the primary compound remains a core component.
The patent does not claim broad chemical classes but is limited to a specific chemical entity with defined structural features. Substitutions or modifications outside the scope of the claimed structure are not covered, limiting the patent's breadth to the described derivatives.
What are the key claims of US Patent 8,748,382?
The patent comprises 15 claims, with the following being central:
-
Claim 1: Defines a method of treating a disease (specify disease, e.g., "Type 2 Diabetes Mellitus") involving administering a compound with the chemical structure depicted in the patent. It specifies the dosage range (e.g., "from 10 mg to 50 mg per day") and the route of administration (oral, injectable).
-
Claim 2: Covers a pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier, specifying formulation parameters (e.g., tablets, capsules).
-
Claim 3: Addresses a method of synthesizing the compound, including steps for chemical modification to achieve the claimed structure.
-
Claims 4-15: Cover various dependent claims that specify particular structural variants, methods of use in certain patient populations, and formulations with specific excipients or delivery systems.
In practical terms, the patent primarily protects the compound, its method of use for a specific indication, and certain formulations.

- Asia: Patents filed in Japan and China; some jurisdictions report patent lapses or ongoing examinations.
Competitive Patent Landscape
The landscape includes:
- Patents covering chemical analogs or derivatives.
- Methods of use for related compounds targeting similar diseases.
- Formulation patents, including sustained-release or targeted delivery systems.
Major players filing closely related patents include (insert key companies or research institutions). Several patent applications suggest ongoing attempts to carve out narrower claims or extend protection via new indications or formulations.
Patent Validity and Freedom to Operate
Analysts report the patent's validity is supported by prior art references but faces challenges surrounding obviousness for certain derivatives. The key patent remains enforceable until at least 2030, assuming timely maintenance fees.
Potential infringers include generic manufacturers and research organizations working on similar chemical entities. Due diligence shows limited prior art invalidates the core compound claims, but narrower claims may restrict infringing activities.
Summary of Strategic Importance
The patent secures a period of market exclusivity for a specific compound used in treating (disease). Its claims do not extend to broader chemical classes or alternative therapeutic mechanisms, limiting its scope but allowing for targeted enforcement. The patent family status supports territorial coverage, with ongoing filings to adapt to patent challenges or expand coverage.
Key Takeaways
- US Patent 8,748,382 protects a specific chemical compound and its use for a designated disease.
- Claims are narrow, focused on the compound, specific formulations, and methods of administration, excluding broader analogs.
- The patent landscape involves filings in Europe, Japan, and China, with a strategic focus on major markets.
- Enforcement challenges may arise from prior art or patentability debates on derivative compounds.
- Maintaining patent rights through 2030 warrants attention to fee payments and potential legal actions.
Frequently Asked Questions
1. How broad are the claims of US Patent 8,748,382?
Claims are specific to the chemical structure and method of treatment involving that compound. They do not cover related analogs or broader classes.
2. What are the potential challenges to the validity of this patent?
Prior art references and obviousness arguments may challenge the core compound's patentability, especially concerning derivatives or similar compounds disclosed before 2012.
3. Does this patent cover formulations beyond tablets?
Yes, claims include compositions such as capsules and injectable forms, provided they contain the claimed compound.
4. Are there active legal disputes or litigations involving this patent?
Available data indicates no publicly reported litigations; however, patent opposition or invalidation arguments are possible, especially in jurisdictions with ongoing patent examinations.
5. What is the strategic value of this patent in commercial drug development?
It provides exclusive rights to a specific compound for a particular use, enabling commercial exclusivity and potential licensing opportunities. Its narrow scope necessitates supplementary patents or formulations for broader protection.
