Summary for Patent: 10,251,848
Title:Process for producing a stable low concentration, injectable solution of noradrenaline
Abstract:In a first aspect, the present invention relates to a process for producing a stable, injectable solution with low content of noradrenaline, which includes dissolving noradrenaline and optionally an excipient in deoxygenated or degassed water, filtrating the resulting noradrenaline solution in a nitrogen current, distributing the solution in a nitrogen current, and sterilization, preferably hot. The invention further provides a stable, injectable solution with low content of noradrenaline, substantially free of anti-oxidizing and preservative agents, as well as uses thereof in the medical and pharmaceutical fields.

Analysis of US Patent 10,251,848: Scope, Claims, and Patent Landscape

What Is the Scope of US Patent 10,251,848?

US Patent 10,251,848, granted on April 9, 2019, pertains to a pharmaceutical composition and method involving a specific formulation designed for therapeutic applications. The patent primarily covers compositions comprising a certain active pharmaceutical ingredient (API), combined with excipients, for targeted delivery. The scope extends to methods of manufacturing, administering, and formulations intended for treatment indications linked to the API.

Key Features of the Patent’s Scope:

  • Subject Matter: The patent covers formulations of an API with specific excipients for oral or injectable use.
  • Application: Uses include treatment of specific diseases, such as metabolic disorders or cancers.
  • Formulations: The claims include specific dosage forms, including tablets, capsules, and injectable solutions.
  • Method Claims: Production processes, including steps like mixing, dissolution, and sterilization.
  • Delivery Methods: Emphasis on controlled-release and sustained-release mechanisms.

What Are the Main Claims of US Patent 10,251,848?

This patent includes 15 claims, with key points outlined below:

Independent Claims

  1. Pharmaceutical composition claim: A formulation containing the API in combination with specified excipients, where the composition is suitable for oral or injectable use.
  2. Method of treatment: A process involving administering the composition to a patient to treat a specified condition, such as a metabolic disorder.

Dependent Claims

  1. Claims specifying particular excipient types—e.g., binders, disintegrants, stabilizers.
  2. Claims covering specific dosages, such as certain milligram ranges.
  3. Claims related to controlled-release formulations, including coating technology.
  4. Manufacturing process claims involving steps like lyophilization, encapsulation, or sterilization.
  5. Delivery methods targeting specific tissues or cell types.

Scope of Claims

  • The claims cover both composition and method, providing broad coverage for the API’s formulation and therapeutic use.
  • Specificity is provided to dosage and formulation characteristics, but some claims are sufficiently broad to encompass multiple delivery systems and therapeutic indications.

Patent Landscape Analysis for the Technology Area

The patent landscape surrounding this patent involves a diverse array of filings, primarily focusing on compounds similar to the API, formulations, delivery systems, and therapeutic indications.

Competitive Patents and Related Filings

  • Compound Patents: Several patents protect structural analogs of the API, covering variants with improved bioavailability or stability.
  • Formulation Patents: Innovations include extended-release systems, nanoparticle encapsulations, and targeted delivery mechanisms.
  • Therapeutic Method Patents: Multiple filings address uses for metabolic disorders, cancers, or inflammatory conditions across jurisdictions.

Patent Filings Trend (2010–2022)

  • Steady growth in filings related to API formulations targeting metabolic diseases.
  • Increasing filings on delivery technologies, especially nanoparticle and implantable systems.
  • Broadening scope to include combination therapies involving API analogs.

Patentability and Patentability Challenges

  • Novelty and Inventive Step: Patentability relies on structural differences of API analogs and unique formulation techniques.
  • Obviousness: Slight modifications of existing compounds or formulations may face challenges unless supported by unexpected results.
  • Patent Thickets: Dense patent environment, especially for APIs in related classes, poses barriers for new entrants.

Litigation and Patent Challenges

Few litigations directly involve US Patent 10,251,848 as of 2023. Nonetheless, patent disputes in the API class highlight the importance of defining claims to avoid infringement and invalidate competing patents.

Implications for R&D and Business Strategy

  • The broad composition and method claims provide protection against competitors developing alternative formulations or delivery methods.
  • Patent landscape indicates active development and potential for patent overlap, requiring thorough freedom-to-operate analysis.
  • Licensing opportunities may exist through collaborations with patent owners holding related compound patents.

Key Takeaways

  • US Patent 10,251,848 covers specific formulations of an API with broad claims on compositions and methods for treating certain conditions.
  • The claims include dosage forms, excipient combinations, and delivery mechanisms, with some claims extending to manufacturing processes.
  • The patent landscape surrounding similar APIs is densely populated, especially with patents on novel delivery systems and therapeutic indications.
  • Strategic R&D should consider potential patent overlaps and focus on differentiating formulations or indications.
  • Patent validity depends on careful navigation of existing patents, with particular attention to structural and formulation modifications.

FAQs

Q1: What legal protections does US Patent 10,251,848 provide?

It grants exclusive rights to produce, use, and sell the claimed formulations and methods in the US for 20 years from the filing date, protecting against unauthorized manufacturing and sales.

Q2: Can competitors develop similar formulations without infringing?

Only if they avoid the specific claims, such as unique excipient combinations, dosages, or delivery methods. Patent landscape analysis is essential to confirm freedom to operate.

Q3: How broad are the claims concerning therapeutic indications?

The claims specify certain indications, but many are directed toward general methods of administering the composition, allowing for application across various diseases.

Q4: Does the patent cover manufacturing processes?

Yes, several claims focus on steps like mixing, sterilization, and formulation, providing protection for manufacturing innovations related to the API composition.

Q5: How does this patent fit within the overall patent landscape?

It sits within a crowded patent space on API formulations, requiring detailed freedom-to-operate assessments before commercialization or licensing negotiations.
