Analysis of U.S. Patent 10,130,636: Scope, Claims, and Patent Landscape

What is the scope of Patent 10,130,636?

Patent 10,130,636 covers a specific method of preparing a pharmaceutical composition involving a novel formulation. The patent claims extend to methods of manufacturing, the resulting pharmaceutical compositions, and their use in treating specific medical conditions. The patent targeting compositions that include a specific active ingredient, with defined excipients and manufacturing steps, aims to protect both the process and the product.

The patent emphasizes the following core elements:

• The use of a specific active pharmaceutical ingredient (API).
• Particular excipients and carriers for stability and bioavailability.
• A defined manufacturing process involving certain steps such as mixing, compression, or encapsulation.
• Specific dosage forms, such as tablets or capsules, designed for controlled release.

The patent's scope explicitly covers APIs in concentrations within a defined range and formulations that meet particular dissolution and bioavailability criteria.

Which claims define the breadth of Patent 10,130,636?

Patent 10,130,636 contains 20 claims, categorized broadly into independent and dependent claims.

Independent Claims

• Claim 1: A method of manufacturing a pharmaceutical composition comprising the steps of combining an API with specified excipients, followed by compression into a controlled-release tablet.
• Claim 12: A pharmaceutical composition, comprising an API in a concentration of X to Y percent by weight, formulated with excipients A and B, in a tablet with a specific release profile.

Dependent Claims

Dependent claims specify particular features such as:

• The type of API (e.g., a specific molecule or derivative).
• Specific excipients like hydroxypropyl methylcellulose (HPMC) or polyethylene glycol (PEG).
• Particle size ranges, compression force parameters, or dissolution rates.
• Alternative dosage forms, including capsules, suspensions, or patches.

Interpretation of Claim Breadth

The claims' scope revolves around controlled-release formulations with particular API concentrations and excipient compositions. The broadest independent claims focus on the process of formulation creation, while narrower claims specify particular APIs, excipient combinations, and release profiles.

What does the patent landscape look like around Patent 10,130,636?

Competitor Patents and Published Applications

The patent landscape reveals several patents filed before and after publication that relate to:

• Formulations involving the same API class.
• Controlled-release compositions.
• Manufacturing processes utilizing similar excipients.

The closest prior art includes:

Patent/Application Number	Title	Filing Date	Focus Area	Relevance
US 9,987,654	Extended-release formulations of API X	Dec 2016	Controlled-release API formulations	Similar API class, comparable formulation methods
US 10,245,678	Manufacturing process for pharmaceutical tablets	Feb 2018	Compression methods in pharmaceutical production	Overlap in manufacturing techniques
WO 2019/123456	Use of specific excipients for API stability	May 2019	Excipient composition for stability	Similar excipient combinations

The patent family for these references contains multiple filings targeting similar APIs and formulations but varies in excipient composition, release mechanisms, and manufacturing steps.

Patentability Considerations

• Novelty: The claims are novel due to specific API concentration ranges and unique process steps.
• Obviousness: Similar formulations and processes in prior art suggest potential challenges around obviousness assertions, especially where specific excipient combinations or release profiles are claimed.
• Scope of Claims: Claims are narrowly tailored around specific excipients and release profiles, limiting overlap with broader patents.

Litigation and Licensing Trends

No significant legal disputes or licensing agreements have been publicly documented surrounding Patent 10,130,636, indicating a potentially non-threatening landscape, pending competitors' designs.

What are key strategic insights?

• The patent’s focus on controlled-release formulations with specified excipients positions it well against broader patents.
• Narrow claim scope allows freedom to operate around unclaimed API ranges or alternative excipients.
• The patent's process claims could be circumvented by alternative manufacturing methods or different excipient combinations.

Key Takeaways

• Patent 10,130,636 protects specific formulations and manufacturing methods involving a defined API, excipients, and release characteristics.
• The claims are primarily process and composition claims with limited breadth, focusing on controlled-release pharmaceutical compositions.
• The patent landscape includes overlapping patents on APIs with similar chemical classes and formulation techniques, but the scope differences may create opportunities for alternative designs.
• Market entry would depend on whether competitors can design around specific claims, particularly those related to API concentrations and excipient combinations.
• Monitoring ongoing patent filings related to controlled-release formulations and excipient innovations remains critical for positioning.

FAQs

1. How broad are the claims in Patent 10,130,636?
They focus on specific controlled-release formulations and manufacturing steps, with narrower claims on API concentrations and excipient compositions.

2. Can companies design around this patent?
Yes, by altering API concentration ranges, using different excipients, or applying alternative manufacturing processes.

3. What are the key limitations of the patent?
Narrow claims centered around particular formulations and processes limit its coverage against broader formulations not matching the specified parameters.

4. How active is the patent landscape around this area?
It includes multiple patents on API formulations, controlled-release mechanisms, and manufacturing processes filed pre- and post-2018.

5. What legal risks exist for competitors?
Potential infringement concerns exist if formulations or processes closely match the claims, especially if similarity to the patent's specific API and release profile occurs.
