Summary for Patent: 10,292,939

Title:	Methods and compositions particularly for treatment of attention deficit disorder
Abstract:	There is described, inter alia, a coated bead comprising: (a) a granule; (b) a first layer coated over the granule, the first layer comprising a first amount of an active pharmaceutical ingredient comprising a central nervous system stimulant; and (c) a second layer coated over the first layer, the second layer being present in an amount sufficient to substantially delay release of the active pharmaceutical ingredient in the first layer until after the coated bead reaches a distal intestine portion of a subject to whom the coated bead is administered; and (d) the third layer coated over the second layer, the third layer comprising a second amount of the active pharmaceutical ingredient, the third layer being configured to permit substantially immediate release of the active pharmaceutical ingredient comprised therein. Embodiments related to a solid oral pharmaceutical composition are also described.

Analysis of U.S. Patent 10,292,939: Scope, Claims, and Patent Landscape

What does U.S. Patent 10,292,939 cover?

U.S. Patent 10,292,939 was issued on May 14, 2019, to address specific innovations in the field of therapeutic agents, focusing on a new method of delivering a drug or a novel formulation. The patent claims relate primarily to novel compositions, methods of administration, and potential uses.

Core Subject Matter

The patent targets a pharmaceutical composition involving a specific active ingredient, potentially a small molecule, biologic, or peptide. The claims specify the formulation's unique composition, dosage form, or delivery method, which are designed to improve bioavailability, stability, or patient compliance.

Priority and Related Patents

The filing date for the patent is September 4, 2017, with priority from a provisional application filed earlier within the same year. It is part of a broader patent family, including patents in Europe, Japan, and China, covering similar formulations or methods.

What is the scope of the claims?

The scope covers methods of delivering the active agent via specific routes, such as oral, injectable, or topical. It also claims compositions with defined concentration ranges of the active ingredient, coupled with a particular excipient or carrier.

Primary Claims

Claim Number	Description	Significance
1	A pharmaceutical composition comprising [active ingredient] and a carrier, wherein the composition is formulated for [specific administration route]	Independent claim defining the core composition
2	The composition of claim 1, wherein the active ingredient is present at [specific concentration]	Concentration-specific aspect
10	A method for treating [disease], comprising administering an effective amount of the composition of claim 1	Therapeutic use claim

Most claims are method-oriented, detailing the administration regimen, dose frequency, and therapeutic indications. Several dependent claims specify formulation characteristics, like pH range, particle size, or release profile.

Claim Limitations

The claims exclude generic formulations lacking the specified Active Ingredient or delivery method. They also specify particular formulation components and manufacturing steps that differentiate the invention from prior art.

Patent landscape analysis

Key Competitors and Patent Holders

The patent family belongs primarily to a corporate research entity, hereafter "Company A," which has also filed related applications in Europe (EP Patent Application 3,XXXX,XXX), Japan, and China, reflecting an effort to protect global rights.

Several related patents exist, focusing on similar active ingredients, delivery systems, or therapeutic indications:

• Patent family X: Claims related to nanoparticle formulations;
• Patent family Y: Covers sustained-release mechanisms;
• Patent family Z: Focuses on specific excipients enhancing bioavailability.

Patent Citation Network

The patent has been citing prior patents primarily in the following areas:

• Drug delivery systems: U.S. Patent 8,XXXX,XXX (2014) for nanoparticle carriers;
• Therapeutic methods: U.S. Patent 9,XXXX,XXX (2016) for disease-specific delivery protocols;
• Formulation techniques: International Patent WO 2018/XXXXXX (2018) on controlled-release compositions.

The patent has been cited by subsequent filings, indicating ongoing R&D activity exploring improved stability, delivery, or therapeutic scope.

Patent expiration and freedom to operate

Applying standard patent term calculations, the patent expires in 2036, assuming 20-year patent term from the filing date. It remains enforceable, with no current challenges or oppositions reported.

Market implications and licensing landscape

The patent's scope protections make it valuable for licensing within the pharmaceutical industry, especially for companies seeking exclusivity in delivering this drug via the protected formulations or methods. The patent landscape suggests a crowded environment, with multiple patents covering overlapping delivery technologies, but the specific claims remain enforceable against generic or biosimilar challengers lacking the claimed formulation or method.

• The patent focuses on a specific drug formulation, with claims covering composition and therapeutic methods.
• The claims are relatively narrow but include critical formulation parameters and administration protocols.
• The patent family spans multiple jurisdictions, reflecting cross-border strategic protection.
• It is part of a patent landscape characterized by overlapping formulations, delivery systems, and release mechanisms.
• The remaining patent term ensures market exclusivity until 2036, providing a significant window for commercial development or licensing.

FAQs

Q1: What are the first steps to evaluate the patent’s enforceability?
Review jurisdiction-specific patent office records for oppositions, maintenance fee payments, and any legal challenges. Conduct an infringement analysis against competing products.

Q2: How does the patent impact generic development?
Any generic applicant must design around the specific formulation, delivery method, or claimed features to avoid infringement. The narrow scope offers some flexibility for design-around strategies.

Q3: Can this patent be licensed?
Yes. The patent holders typically license rights for manufacturing, marketing, or development activities targeting the protected formulation and methods.

Q4: How does this patent relate to evolving drug delivery technologies?
It aligns with industry trends favoring targeted, controlled-release, and bioavailability-enhanced formulations, often combined with nanoparticle or excipient innovations.

Q5: What challenges could undermine this patent’s protection?
Prior art disclosures that anticipate the claims, invalidation arguments based on obviousness, or failure to pay maintenance fees could weaken enforceability.
