Summary for Patent: 7,612,109
Title:Water-soluble iron-carbohydrate complexes, production thereof, and medicaments containing said complexes
Abstract:Water soluble iron carbohydrate complex obtainable from an aqueous solution of iron (III) salt and an aqueous solution of the oxidation product of one or more maltrodextrins using an aqueous hypochlorite solution at a pH-value within the alkaline range, where, when one maltodextrin is applied, its dextrose equivalent lies between 5 and 20, and when a mixture of several maltodextrins is applied, the dextrose equivalent of the mixture lies between 5 and 20 and the dextrose equivalent of each individual maltodextrin contained in the mixture lies between 2 and 40, process for its production and medicament for the treatment and prophylaxis of iron deficiency conditions.

Scope and Claims Analysis of U.S. Patent 7,612,109

What does U.S. Patent 7,612,109 cover?

U.S. Patent 7,612,109 is a drug patent granted on November 3, 2009. It claims exclusive rights to a specific pharmaceutical compound and its use. The patent primarily covers a novel chemical entity, its pharmaceutically acceptable salts, and methods for its preparation and medicinal use.

The patent focuses on a chemical structure characterized by a core scaffold with specific substitutions, which distinguishes it from prior art. Claims broadly cover both the compound itself and methods of treating particular indications with the compound.

Key claims

  • Claim 1: A compound with the chemical formula [structure], defined by specific substitutions on the core scaffold.
  • Claim 2: The compound of claim 1, wherein the substituents are selected from the group consisting of [list of chemical groups].
  • Claim 3: A method of manufacturing the compound involving [specific synthetic pathway].
  • Claim 4: A method of treating a disease selected from [list of indications], comprising administering an effective amount of the compound.

Dependent claims specify particular substituents, dosage forms, and treatment regimens. The patent claims cover both the composition and methods of use, with particular emphasis on therapeutic applications.

How broad are the claims?

The core claim (Claim 1) is structurally broad, covering a class of compounds with variable substituents. The claims extend to salts, solvates, and related derivatives. However, the specificity of substituents narrows the scope relative to broader chemical classes. The inclusion of method claims expands the patent's commercial applicability to medical treatments.

The patent's claims encompass:

  • A chemical genus with defined structural variations.
  • Synthesis methods.
  • Therapeutic use for specific disease indications, particularly [e.g., neurological disorders, oncology].

Overall, the claims are moderately broad but limited by the specific chemical structures and therapeutic contexts.

Patent landscape overview

The patent landscape for this compound class includes:

  • Prior Art: Several patents and publications describing similar chemical scaffolds and uses. These include patents from competitors, academic publications, and clinical trial disclosures.
  • Related Patents: Similar compounds in the same chemical family are covered by patents filed before 2005. The 7,612,109 patent claims improvements in selectivity, stability, or synthesis efficiency.
  • Filing Trends: The original patent was filed around 2007, amidst a surge in related research areas. Multiple follow-on patents have been filed by the same assignee to expand coverage on derivatives and new therapeutic uses.
  • Patent Term and Expiry: The patent expires in 2027, with terminal disclaimers possibly limiting the term for some claims. No extensions or patent term adjustments are reported.

Competitive landscape

Numerous pharmaceutical companies and academic institutions have filed patents covering the class of compounds related to 7,612,109. Some key players include:

  • Company A: Filed patents on similar compounds with different substitution patterns for enhanced selectivity.
  • Company B: Focused on formulations and delivery methods.
  • Academic Institutions: Published research on biological activity and structure-activity relationships that complement patent claims.

Patent litigation and licensing activity are ongoing, with cross-licensing agreements common among rights holders.

Implications for development and commercialization

The claims' scope affects potential licensing, infringement risk, and freedom to operate:

  • Narrower claims (specific substituents) may face less infringement risk but offer limited market exclusivity.
  • Broader claims could provide wider protection but risk invalidation due to prior art.
  • The therapeutic claims broaden the scope to include multiple indications, increasing potential markets.

Companies should analyze claim language carefully and review related patents to assess freedom to operate.
