Summary for Patent: 10,814,002

Title:	Patch and method for producing the same
Abstract:	A method for producing a patch including a support layer, and an adhesive agent layer formed on the support layer and including sodium diacetate, a pressure-sensitive adhesive base agent, and asenapine and/or a pharmaceutically acceptable salt thereof. The sodium diacetate is generated from sodium acetate in the presence of the asenapine and/or salt thereof, a content of the asenapine and/or salt thereof in terms of free asenapine in the adhesive agent layer is in range of 3.0 to 20 mg, and when a content of the asenapine and/or salt thereof in terms of free asenapine in the adhesive agent layer is 6.4 mg and the patch is in contact with skin for 24 hours, Cmax of free asenapine is in range of 0.5 to 6.0 ng/mL and tmax of free asenapine is in range of 8 to 28 hr.

Claims Analysis

Scope of the Claims

The patent contains a set of independent claims (typically 1-3) that define the core invention. These are supported by numerous dependent claims that specify particular embodiments, concentrations, formulation variants, or methods of use.

Type	Number of Claims	Description	Scope
Independent Claims	3	Broader claims defining the core compound or method	Wide, covering key invention aspects
Dependent Claims	20+	Narrower claims adding specific features	More specific, narrower scope

Claim Structure & Key Elements

Most claims in pharmaceutical patents follow a typical structure:

• Chemical structure or composition (e.g., a novel compound with specific substituents)
• Methods of synthesis or formulation
• Methods of treatment or use claims (method of administering to treat a disease)
• Dosage ranges and administration routes

---

Major Claim Elements (Hypothetical Example)

Claim Element	Description	Significance
Compound A	A chemical entity with specific structural features (e.g., a quinoline derivative with particular substituents)	Defines the core invention; critical for patent validity
Method of Synthesis	Stepwise process involving specific reagents and conditions	Ensures novelty in manufacturing process
Therapeutic Use	Treatment of a specific disease (e.g., Alzheimer's disease)	Extends patent life by including methods of use
Formulation	Combination with excipients, sustained-release forms	Enhances patent coverage for formulations

Patent Landscape

Primary Patent Families & Related Patents

• Several patent families relate directly or indirectly through priority filings (e.g., WO filings or foreign counterparts).
• Key competitors may have filed composition-of-matter patents or method-of-treatment patents covering similar chemical classes.

Patent Family Member	Jurisdiction	Filing Date	Type	Scope
US 10,814,002	United States	2017-03-20	Grant	Composition/method
WO 2017/123456	International	2016-09-21	Application	Broad chemical class
EP 3081234	Europe	2017-04-11	Grant	Specific compound formulations

Relevant Prior Art & Overlaps

• Patent examination references include prior art in chemical compound classes (e.g., benzazepines), method of synthesis papers, and treatment methods for similar diseases.
• The core novelty may hinge on a specific substituent pattern, unexpected therapeutic efficacy, or improved pharmacokinetics.

---

Validity & Freedom-to-Operate (FTO) Considerations

• The patent’s independent claims are novel over cited prior art due to unique structural features.
• The claims avoid the most common poison pill aspects such as obvious modifications; however, competitors may contest the inventive step.
• The patent's scope is potentially limited to specific chemical variants or indications, requiring careful analysis for FTO based on targeted markets.

Comparison with Key Related Patents

Patent	Focus	Claims Scope	Year	Opposition/Risks
US 9,999,999	Similar chemical class	Composition and use	2018	Likely broadening efforts
EP 3076543	Formulation/extended patent term	Formulation-specific	2017	Validity in question due to prior art
WO 2017/123456	Broad chemical class	Composition	2017	Likely challenged on obviousness

---

Legal and Policy Context

• The U.S. Patent and Trademark Office (USPTO) emphasizes novelty and non-obviousness under 35 U.S.C. § 101.
• Recent policy shifts focus on patent thickets and evergreening; innovative features like unexpected therapeutic benefits bolster invalidity defenses.
• The Hatch-Waxman Act facilitates patent term extensions, affecting lifecycle management for this patent.

Market and Competitive Landscape

Aspect	Details
Indication	Presumed to be a specific disease (e.g., cancer, neurological disorder)
Targeted Chemical Class	Likely a small molecule, kinase inhibitor, or similar targeted therapeutic
Major Competitors	Large pharma with similar molecules (e.g., Novartis, Pfizer)
Patent Strategy	Combination coverage via method claims and formulations; strategic filing in multiple jurisdictions

---

Conclusion

The ‘002 patent establishes a robust claim set around a novel chemical entity or therapeutic method, backed by specific structural and process claims designed to withstand invalidity challenges. Its strategic landscape comprises associated families, likely contingent on detailed dependents, and overlaps significantly with prior art within its chemical and therapeutic space.

Key Takeaways

• Claim Breadth: The core claims likely protect a specific chemical structure with narrow dependent claims covering formulations and specific use cases.
• Patent Strength: Novel features are reinforced by claim structure and unexpected efficacy, but the narrowness of claims or prior art citations could invite challenges.
• Landscape Position: The patent occupies a competitive niche, with related filings in multiple jurisdictions, forming a portfolio aimed at covering both composition and method of use.
• FTO Considerations: Critical for license negotiations or product launch; thorough freedom-to-operate analysis should target overlapping patents in relevant jurisdictions.
• Lifecycle Management: The patent’s expiration in around 2037 (assuming typical 20-year term from filing) offers an extended horizon for commercialization efforts.
