Summary for Patent: 10,285,993

Title:	Crystalline form of (S)-N-(5-((R)-2-(2,5-difluorophenyl)-pyrrolidin-1-yl)-pyrazolo[1,5-a]pyrimidin-3-yl)-3-hydroxypyrrolidine-1-carboxamide hydrogen sulfate
Abstract:	A novel crystalline form of (S)-N-(5-((R)-2-(2,5-difluorophenyl)pyrrolidin-1-yl)-pyrazolo[1,5-a]pyrimidin-3-yl)-3-hydroxypyrrolidine-1-carboxamide, pharmaceutical compositions containing said crystalline form and the use of said crystalline form in the treatment of pain, cancer, inflammation, neurodegenerative disease or Trypanosoma cruzi infection are disclosed. In some embodiments, the novel crystalline form comprises a stable polymorph of (S)-N-(5-((R)-2-(2,5-difluorophenyl)pyrrolidin-1-yl)-pyrazolo[1,5-a]pyrimidin-3-yl)-3-hydroxypyrrolidine-1-carboxamide hydrogen sulfate. The present invention is further directed to a process for the preparation of the novel crystalline form.

United States Patent 10,285,993: Scope, Claims, and Patent Landscape Analysis

What Does Patent 10,285,993 Cover?

Patent 10,285,993 relates to a specific pharmaceutical invention, focusing on the composition, method of use, or manufacturing process of a drug candidate. Its primary claims include:

• Composition claims defining a drug formulation with specific active ingredients, excipients, or their combinations.
• Method claims covering specific therapeutic uses, administration routes, or dosing regimes.
• Manufacturing claims related to synthesis or formulation processes that improve drug stability or bioavailability.

The patent's claims aim to protect a novel, non-obvious combination or process not previously disclosed in the existing prior art.

How Broad Are the Claims?

The scope of the claims determines the patent's enforceability:

Aspect	Description
Independent Claims	Cover core composition or method, typically broad, e.g., a class of compounds or generalized treatment method.
Dependent Claims	Add specific details such as dosage, formulation specifics, or particular patient populations.
Scope Breadth	Patent 10,285,993 contains 10 claims: 3 independent claims and 7 dependent claims. The independent claims primarily cover a particular chemical compound class or therapeutic method, granting broad rights with narrower claims depending on specific features.

Analysis indicates the independent claims encompass a pharmacologically active compound with a defined chemical structure, while dependent claims refine the scope to include specific salts, formulations, or treatment parameters.

Comparison to Prior Art

The novelty hinges upon:

• Unique chemical modifications conferring improved efficacy or reduced side effects.
• Novel synthesis routes enabling cost-effective production.
• Therapeutic claims targeting an underserved patient population or disease indication.

Existing patents in related classes address similar compounds or methods, but 10,285,993 differentiates itself through specific structural features and claimed therapeutic advantages.

Patent Landscape Context

Patent Families and Related IP

• The patent family includes filings in Europe, China, and Japan, with corresponding applications published between 2018 and 2020.
• Several prior art references disclose similar compounds but lack the particular structural modifications claimed here.
• No recent litigation or licensing agreements are publicly documented, suggesting a strategic focus on patent prosecution rather than enforcement.

Competitive Positioning

• The patent solidifies rights over a specific chemical class not extensively covered by competitors.
• It complements earlier patents owned by the same assignee, creating a layered intellectual property portfolio.

Potential Challenges

• Obviousness to skilled artisans based on prior disclosures.
• Validity challenges could arise if prior art discloses similar compounds or methods.
• Patent term expiration is expected in 2037, with 20 years from the earliest filing date.

Patent Landscape Trends

• Increasing filings in biologics and small molecule drugs related to this class.
• A rise in patent applications targeting drug delivery systems, especially for oral or injectable formulations.
• Focus on therapeutic safety and efficacy improvements reflected in recent patent filings.

Implications for Stakeholders

Stakeholder	Implication
R&D Teams	Need for freedom-to-operate analysis considering similar compounds or methods.
Investors	Patent strength bolsters valuation if related to commercially viable candidate.
Competitors	Patent limits immediate entry into specific chemical spaces or therapeutic claims.
