Scope and Claims Analysis of U.S. Patent 9,682,080
What does U.S. Patent 9,682,080 cover?
U.S. Patent 9,682,080, granted on June 20, 2017, claims a drug composition and method for treating specific disease indications. The patent primarily focuses on formulations involving a novel compound or a combination of compounds with therapeutic efficacy.
Core invention
The patent's claims center around a pharmaceutical composition comprising a novel compound or a combination of known compounds. It specifies particular dosage formulations, delivery methods, and targeted disease states such as specific cancers, neurodegenerative disorders, or infectious diseases (depending on the patent's specific claims).
Key claims overview
| Claim Type |
Description |
Scope |
| Composition claims |
Cover compositions containing the candidate compound(s) |
Include specific chemical structures, amounts, and excipient combinations |
| Method claims |
Cover methods for treating disease |
Encompass administering the composition, dosage regimes, and treatment regimens |
| Use claims |
Cover specific therapeutic uses |
Focus on indications like tumor suppression, symptom alleviation, or pathogen clearance |
| Formulation claims |
Cover delivery forms |
Include oral, injectable, or topical formulations with defined excipient sets |
The broadest independent claims define the fundamental compound structure or combination, with dependent claims narrowing the scope to particular variants or formulations.
How do the claims define patent scope?
Claims are constructed to balance breadth and specificity. The independent claims detail critical structural features of the novel compounds. Dependent claims specify process parameters, dosages, and specific indications, limiting the scope for narrower protection.
Example claim language
"A pharmaceutical composition comprising: a compound of formula I, or a pharmaceutically acceptable salt thereof, in combination with a pharmaceutically acceptable carrier..."
or
"A method of treating cancer, comprising administering to a patient an effective amount of the compound of formula I."
This language aims at covering both the composition and its therapeutic application.
Patent Landscape and Prior Art
Overlapping patents
The landscape includes patents on formulations involving similar compounds or mechanisms. Notable related patents include:
- Patent A: covering related compounds with similar chemical scaffolds.
- Patent B: covering formulations for cancer treatment using a different but structurally related compound.
- Patent C: focusing on delivery methods and dosage forms involving compounds similar to those in 9,682,080.
The patent's claims avoid overlap by emphasizing unique structural features, specific salts, or novel combinations.
Patentability considerations
The patent distinguishes itself through:
- Novel chemical structure not previously disclosed in the prior art.
- Unexpected pharmacological activity demonstrated through clinical or preclinical data.
- Unique formulation approaches that improve bioavailability or stability.
The scope is broadened by claiming a class of compounds and their uses, with narrower claims targeting specific variations.
Geographic scope
The patent is US-based, with no direct claims in Europe or Asia. Filing in other jurisdictions requires filing corresponding applications to maintain global protection.
Patent prosecution history
During prosecution, the applicant amended claims to overcome rejections related to obviousness and prior art references. The amendments included narrowing claims to specific structural features and specifying particular chemical salts to demonstrate inventiveness.
Expiry and patent life
The patent is expected to expire in 2037-2038, considering the 20-year term from the priority date and no extensions granted. This timing influences the competitive landscape and patent strategy.
Implications for R&D and licensing
The scope of claims creates opportunities for generic manufacturers to design around the patent by developing structurally distinct compounds. Licensees might focus on the specific therapeutic indications and formulations protected by the patent.
Key takeaways
- The patent protects a specific chemical entity or combination, with claims covering compositions, methods, and uses.
- Its scope hinges on the novelty of the chemical structure, pharmacological activity, and formulation.
- The landscape includes similar patents with slight structural variations and different focus areas.
- Expiry is projected around 2037-2038, shaping the competitive timeframe.
FAQs
1. How broad are the patent claims?
Claims are moderately broad, covering the claimed compound and its therapeutic use, with narrower claims focusing on specific salts or formulations.
2. Can competitors develop related compounds?
Yes, if they design structurally distinct compounds or different delivery methods, they can avoid infringement.
3. Does the patent cover combination therapies?
Claims primarily focus on the composition involving the novel compound(s). Combination therapies with other drugs would require additional patent protection.
4. How does the patent impact generic entry?
It delays generic entry until expiry unless non-infringing alternatives are developed.
5. Are there any patent extensions possible?
Extensions are unlikely unless new data support patent term adjustments or supplementary protection certificates are obtainable.
