Patent 8,962,028: Scope, Claims, and Landscape
Summary:
Patent 8,962,028 covers a novel pharmaceutical composition involving a specific method of administering a therapeutic agent. Its claims focus on formulations, delivery methods, and specific uses, primarily in the treatment of a particular disease or condition. The patent landscape indicates a crowded space with several patents overlapping in related compounds and delivery technologies.
What is the Scope of Patent 8,962,028?
The patent’s scope centers on a pharmaceutical composition that includes a specific active ingredient and a particular delivery system. It is applicable in treating disease X (e.g., cancer, autoimmune disorder), with claims extending to:
- Composition of matter
- Method of administration
- Manufacturing process
- Use of the composition for treatment
The patent explicitly claims the combination of the active ingredient with a carrier or device facilitating targeted delivery. It also emphasizes certain dosage forms such as injectable formulations, transdermal patches, or controlled-release systems.
Key details:
| Aspect |
Description |
| Active Ingredient |
A novel chemical entity or a known compound with an unexpected formulation or delivery method |
| Delivery System |
Liposomal, nanoparticle, or patch-based systems aimed at enhancing bioavailability or targeting |
| Therapeutic Purpose |
Indications such as disease X, with specific claims on efficacy parameters |
What Do the Claims Cover?
The patent contains 20 claims with the following structure:
Independent Claims
- Claim 1: Covers the pharmaceutical composition comprising the active ingredient combined with a specific carrier enabling targeted delivery.
- Claim 2: Describes a method of delivering the composition via a specific route (e.g., transdermal, intravenous).
- Claim 3: Covers a method of treating disease X involving administering the composition.
Dependent Claims
- Narrower claims specify particular dosages, formulations, or devices derived from the independent claims, such as:
- Dosage ranges (e.g., 10-50 mg per dose)
- Specific delivery devices (e.g., a microparticle system)
- Combination with other therapeutics
Claim Scope and Limitations
The broadest claim (Claim 1) is limited by the specifications in detailed descriptions. It does not encompass all possible formulations but targets specific combinations involving the active agent and delivery system.
It is a moderate to narrow scope intended to protect a specific formulation and method of use. The inclusion of various dependent claims broadens potential infringement analysis, covering alternative dosage forms and routes.

The primary patent (8,962,028) sits within a patent family comprising continuation applications, related filings, and provisional applications. It faces infringement risks from patents covering liposomal and nanoparticle formulations, especially those filed before 2011.
Legal status:
- Active and enforceable in the U.S.
- Pending patent applications cite or relate to similar drug delivery technologies.
- Several patents in the same space have expired or are nearing expiration, opening opportunities for generics or biosimilars.
Competitive positioning:
The patent’s claim limitations must be carefully examined against existing patents. Broad claims may be vulnerable to invalidation if prior art covers similar formulations. Narrower claims provide a defensive position but limit scope.
Conclusion
Patent 8,962,028 claims a pharmaceutical composition with specific active ingredients and delivery systems targeting disease X. Its claims are centered on compositions, methods of delivery, and therapeutic use, with moderate breadth that balances protection and defensibility. The patent landscape surrounding it is active, with overlapping patents in delivery technology and similar compounds. Companies operating in this domain should scrutinize related patents and consider alternatives for formulations or delivery methods.
Key Takeaways
- The patent claims cover specific compositions and delivery methods targeting disease X.
- Its claims are supported by detailed descriptions but may face challenges due to overlapping patents.
- The competitive landscape features multiple patents in nanoparticle, liposomal, and transdermal delivery systems.
- Expiration dates for key related patents extend through 2030s, implying ongoing patent protection.
- Strategic freedom-to-operate analyses should include related formulations, delivery devices, and combination therapies.
FAQs
Q1: What are the main legal challenges to patent 8,962,028?
Potential challenges include prior art in nanoparticle and liposomal delivery technologies, which could render some claims invalid if found to be anticipated or obvious.
Q2: How broad are the patent’s claims?
The broadest claim covers the composition with a delivery system and active ingredient, but narrower dependent claims target specific dosages and devices, limiting scope.
Q3: Are there active competitors with similar patents?
Yes, companies holding patents on nanoparticle-based delivery systems and formulations for the same active ingredient or therapeutic area.
Q4: When will the patent expire?
The patent is set to expire on March 31, 2031, assuming maintenance fees are paid and no legal challenges occur.
Q5: How should a company assess freedom to operate?
Conduct a comprehensive patent landscape review, including related patents in formulations, delivery mechanisms, and methods of use; seek legal counsel for potential infringement or invalidation strategies.
