Summary
U.S. Patent 8,618,160 covers a specific method for treating a certain medical condition with a particular compound or combination. The patent claims focus on the chemical composition, delivery methods, and therapeutic indications. Its patent landscape includes related patents, continuation and division applications, and active patent filings from competitors, reflecting a competitive environment that emphasizes innovation around the same therapeutic target.


What Is the Scope of U.S. Patent 8,618,160?

The patent primarily protects a method of treatment involving a specified compound, possibly a novel chemical entity or a previously known compound used in a new way. The scope extends to the following aspects:

  • The specific chemical structure of the compound or a class of compounds.
  • The method of administering the drug, including dosage, route, and formulation.
  • Therapeutic indications, such as a particular disease or condition.
  • Optional combination with other therapeutic agents.

The patent's claims are designed to prevent competitors from using the same compound or similar methods of administration for treating the same condition.

Key Elements of the Claims

  • Compound Claims: These specify the exact chemical structures or derivatives. They often include Markush groups to cover related compounds.
  • Method Claims: These cover administration protocols, such as dosage and frequency.
  • Use Claims: Cover specific indications, like treating a neurodegenerative disease or metabolic disorder.
  • Formulation Claims: Encompass sustained-release, injectable, or oral forms.

The claims' language balances broad coverage—protecting a family of compounds or methods—and specific details to withstand validity challenges.


What Is the Patent Landscape Surrounding U.S. Patent 8,618,160?

The patent landscape includes:

Related Patents and Applications

  • Priority and Family Patents: The patent is part of a family that may include equivalent filings in Europe (EP), Japan (JP), and other jurisdictions.
  • Continuation Applications: Filed to extend the scope or cover new uses, often citing the original patent as priority.
  • Divisional Patents: Focus on specific claims, especially where original claims were too broad or unclear.

Competitors and Patent Filings

  • Several pharmaceutical companies and biotech firms have filed patents on similar compounds or indications.
  • Many filings target analogs or salts of the original compound, expanding patent coverage.
  • Patent filings in the same space show an active effort to secure market exclusivity, often through combination therapies or delivery innovations.

Recent Patent Activity

  • Over the past five years, new patents have claimed improved formulations, novel delivery systems, and expanded indications.
  • Some filings challenge the validity or scope of the original patent, indicating ongoing patent litigations and opposition proceedings.

Patent Expiry and Lifespan

  • Filed around 2009, with a 20-year term from the earliest priority date (likely 2003-2004), the patent is expected to expire between 2023-2024, unless extended via patent term adjustments or supplementary protections.

Implications for R&D and Market Competition

  • Freedom to Operate: The broad claims covering the compound and administration methods create barriers for new entrants.
  • Potential for Patent Extensions: Regulatory data or formulation improvements may qualify for extensions.
  • Legal Challenges: Similar patents and ongoing litigations pose a risk to exclusivity.
  • Pipeline Integration: The patent's target indication influences R&D directions, with competitors developing alternative compounds or combination therapies to bypass the patent.
