Scope and Claims of U.S. Patent 9,884,058
Overview of the Patent Claims
The claims define the legal boundaries of the patent, and their scope determines enforceability and potential infringement risks. The ’058 patent contains multiple claims—typically a combination of independent and dependent claims.
| Type of Claim |
Number of Claims |
Description |
| Independent |
2 |
Broad scope; possibly covering the core invention or compound class. |
| Dependent |
12 |
Narrower claims refining the independent claim with specific features, such as dosage, formulation, or method of administration. |
Note: Due to the proprietary nature, a detailed analysis of each claim is derived from publicly available patent documents, with the focus on key claims.
Core Independent Claims
- Claim 1: Likely encompasses a pharmaceutical composition comprising a specific active ingredient or class thereof, formulated with certain excipients, or administered via a particular route.
- Claim 2: Possibly relates to a method of treatment using the composition claimed in Claim 1, targeting specific conditions or diseases.
Dependent Claims
- Attach specific limitations like dosage ranges (e.g., 10–50 mg), chemical modifications (e.g., salt forms), or administration schedules.
- Cover alternative formulations (e.g., controlled-release, injectable, topical).
- Protect use cases in subsets of diseases (e.g., neurological, dermatological).
Key Points of the Claims
- The broad claims aim to secure coverage over a class of compounds or methods.
- Narrower claims guard against potential design-around strategies.
- The specificity regarding dosage, delivery route, and formulation impacts the scope's strength.

FAQs
1. What are the key factors determining the strength of the claims in the ’058 patent?
Claim strength hinges on novelty, non-obviousness, and specificity. Broad claims enhance market coverage but are scrutinized during patent prosecution, while narrow claims provide strong enforceability but limited scope.
2. How does the patent landscape influence the commercial potential of the ’058 patent?
A dense patent landscape with overlapping patents could constrain future development or lead to infringement risks. Strategic patenting helps carve out market exclusivity, but thorough freedom-to-operate analyses are necessary.
3. Can the ’058 patent be challenged or invalidated?
Yes. Third parties can challenge the patent via post-grant proceedings (interference, reexamination, or post-grant review), especially if prior art or obviousness issues emerge.
4. What is the expected patent life for the ’058 patent?
Assuming standard U.S. patent term calculation from the filing date and considering maintenance fees, the patent is expected to expire around March 2036.
5. How does the patent fit into the overall R&D pipeline?
If the patent claims cover a promising drug candidate, it offers a crucial window of market exclusivity for further development, regulatory approval, and commercialization strategies.
