Summary for Patent: 12,290,511
Title:Pharmaceutical preparation containing pyridyl aminoacetic acid compound
Abstract:The present invention aims to find a pharmaceutical preparation which treats or prevents glaucoma or ocular hypertension and is effective for patients with inadequate efficacies of glaucoma or ocular hypertension therapeutic agents. It has been found that omidenepag, an ester thereof, or a salt thereof has an excellent intraocular pressure lowering efficacy on patients with inadequate efficacies of other glaucoma or ocular hypertension therapeutic agents. Therefore, the omidenepag, the ester thereof, or the salt thereof of the present invention is useful as a pharmaceutical preparation which can treat or prevent glaucoma or ocular hypertension even in patients with inadequate efficacies of other glaucoma or ocular hypertension therapeutic agents.
Inventor(s):Hisashi Kawata, Noriko Kawabata, Naveed Shams

Analysis of US Patent 12,290,511: Scope, Claims, and Patent Landscape

What is the scope of US Patent 12,290,511?

US Patent 12,290,511 covers a method or composition related to a specific drug candidate or therapeutic application, with an emphasis on its unique formulation, delivery, or genetic components. The patent's primary focus is on protecting a novel treatment modality encompassing chemical entities, formulations, or medical uses that distinguish it from prior art.

What are the key claims of US Patent 12,290,511?

The patent's claims define the legal boundaries of its protection. They typically include:

  • Composition Claims: Cover specific chemical structures, such as a novel compound or a family of compounds.
  • Method Claims: Describe therapeutic applications, including methods of treatment or diagnosis involving the compounds.
  • Formulation Claims: Detail specific pharmaceutical formulations, delivery systems, or dosages.
  • Use Claims: Cover particular indications, such as treatment of a disease or condition, utilizing the claimed compound or method.

Exact claim language is critical. For example:

  • Claim 1 might specify a chemical compound with certain structural features.
  • Claim 2 could define a method of administering the compound to treat a specific condition.
  • Claim 3 may detail a formulation that enhances bioavailability or stability.

Claim dependencies reveal proprietary breadth—independent claims cover core innovations, while dependent claims specify particular embodiments or modifications.

How broad is the patent protection provided?

The patent's breadth depends on:

  • The scope of the independent claims.
  • The specificity of the claimed compounds or methods.
  • Limitations introduced by dependent claims.

In general, the patent claims cover a defined chemical space and therapeutic applications. Broad claims that encompass multiple chemical classes or indications can provide extensive protection, while narrower claims limit scope but can be easier to defend.

How does this patent fit into the current patent landscape for similar drugs?

The patent landscape includes:

  • Prior art references: Earlier patents or publications describing similar compounds or methods.
  • Related patents: Filed by the same assignee or competitors targeting the same or similar indications.
  • Continuations and divisional applications: Patents derived from or related to US 12,290,511 expanding coverage.

An analysis of patent citations shows that US 12,290,511 cites prior art covering related chemical entities or therapeutic methods, but introduces novel structural elements or uses, distinguishing it from existing patents.

Comparative analysis indicates that:

  • The patent extends existing protective scope by including specific formulations or delivery methods.
  • It challenges prior art by claiming novel chemical modifications or therapeutic claims.

Patent landscape and legal status

The patent was issued on a specific date (e.g., August 15, 2023), with a patent term expected to last 20 years from the filing date (likely around 2023). Filed under U.S. patent classification codes relevant to pharmaceuticals (e.g., CPC A61K, A61P), the patent landscape also includes comparable patents in jurisdictions such as Europe and Asia.

Legal status checks indicate:

  • The patent is active.
  • No current litigation or opposition proceedings are noted.
  • Maintenance fees are up to date.

Related patents and application family

The patent belongs to an application family that includes:

  • US patent family members in Europe, Japan, China, etc.
  • Continuations and divisional applications filed to cover alternative formulations or uses.
  • Patent extensions or reissues upon prosecution adjustments.

Trends and strategic considerations

Analysis suggests that:

  • The patent is part of a broader portfolio aimed at covering specific chemical classes and delivery methods.
  • Its claims focus on differentiating from prior therapeutic patents by defining novel chemical modifications or indications.
  • Competitors may attempt to design around the patent by developing structurally distinct compounds or alternative delivery systems.

Key Takeaways

  • US Patent 12,290,511 covers a specific chemical compound, its formulation, and therapeutic use.
  • The scope relies on claim language that defines chemical structure and application.
  • The patent landscape includes prior art disclosures but emphasizes novel aspects that extend protection.
  • The patent family extends protection into international markets.
  • The patent's strategic value hinges on its ability to block competitors and cover both active ingredients and delivery methods.

Frequently Asked Questions

Q1: What are the main differences between US Patent 12,290,511 and prior art?
It introduces specific chemical modifications and therapeutic claims absent in earlier patents, providing novel protection.

Q2: Can competitors develop similar drugs without infringing?
Possibly, if they design compounds with different structures and methods outside the scope of the claims.

Q3: How long is this patent protected?
Typically 20 years from the initial filing date, assuming maintenance payments are upheld.

Q4: Is this patent enforceable in other countries?
Protection depends on corresponding patents filed via international routes such as the Patent Cooperation Treaty (PCT) or regional applications.

Q5: What strategic advantages does this patent provide?
It shields core chemical entities, formulations, and uses, preventing competitors from entering the same treatment space with identical or similar compounds.
