Understanding the Scope and Claims of United States Patent 8,609,896

Introduction to Patents and the USPTO

The United States Patent and Trademark Office (USPTO) is the agency responsible for granting U.S. patents and registering trademarks. Patents are a form of intellectual property that grant inventors the exclusive right to make, use, import, sell, or offer for sale their inventions for a limited time, typically 20 years from the date of the patent application[1][2][5].

Overview of Patent 8,609,896

United States Patent 8,609,896, titled "Ferric organic compounds, uses thereof and methods of making same," was granted to inventors who developed novel forms of ferric organic compounds, including a form of ferric citrate. These compounds are notable for their solubility over a wider range of pH levels.

Types of Patents

The USPTO grants three main types of patents: utility patents, design patents, and plant patents. The patent in question, 8,609,896, falls under the category of a utility patent, which is granted for "any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof"[1][5].

Patent Application Process

To obtain a patent like 8,609,896, the inventors would have filed a utility patent application with the USPTO. This process involves submitting several documents, including a specification, drawings if necessary, an oath or declaration, an application data sheet, a transmittal letter, and the required fees. The application can be filed electronically through the USPTO's Electronic Filing System (EFS-Web) or by mail/hand delivery, though the latter incurs an additional fee[5].

Patent Claims

The claims in a patent application are crucial as they define the scope of the patent's protection. For Patent 8,609,896, the claims would specify the exact nature of the ferric organic compounds, their uses, and the methods of making them. These claims must be clear, concise, and supported by the specification and drawings provided in the application[5].

Patentability Requirements

For an invention to be patentable, it must meet several criteria:

  • Usefulness: The invention must be operable and provide some tangible benefit.
  • Novelty: The invention must not be fully anticipated by prior patents, publications, or other state of the art knowledge.
  • Nonobviousness: The invention must not have been readily within the ordinary skills of a competent artisan at the time it was made[1][5].

Examination Process

After filing, the patent application undergoes an examination process by a USPTO examiner. The examiner reviews the application, including the claims, to ensure compliance with legal requirements and conducts a prior art search to determine if the claimed invention is useful, novel, and nonobvious. If the examiner finds issues, an Office Action is issued detailing the reasons for rejection or objections. The applicant can then respond to these issues, and if necessary, appeal the examiner's decision or request continued examination[5].

Scope of Patent 8,609,896

The scope of Patent 8,609,896 is defined by its claims, which outline the specific ferric organic compounds and their applications. Here are some key aspects of the scope:

Ferric Organic Compounds

The patent covers novel forms of ferric organic compounds, particularly a form of ferric citrate that is soluble over a wider range of pH levels. This solubility makes these compounds useful in various applications where traditional ferric compounds might not be effective[4].

Methods of Making

The patent also includes methods for making these ferric organic compounds. These methods are crucial as they provide a clear pathway for reproducing the invention, which is a requirement for patentability[4].

Uses Thereof

The patent specifies the various uses of these ferric organic compounds. Understanding these uses is essential for determining the commercial and practical scope of the patent[4].

Impact on the Patent Landscape

Innovation and Productivity

Patents like 8,609,896 contribute to innovation and productivity by providing inventors with exclusive rights to their inventions, thereby incentivizing further research and development. The correlation between the U.S. patent system and productivity growth is well-documented, highlighting the importance of a robust patent system in driving economic progress[1].

Patent Quality and Scope

The debate over patent quality and scope is ongoing. Patents with narrower claims, like those in 8,609,896, are often associated with a higher probability of grant and a shorter examination process. This suggests that well-defined and specific claims can streamline the patent process and reduce litigation costs[3].

Licensing and Litigation

The clarity and specificity of the claims in Patent 8,609,896 can also impact licensing and litigation. Clear and well-defined claims reduce the ambiguity that can lead to costly licensing disputes and litigation, thereby promoting a more stable and predictable patent landscape[3].

Key Takeaways

  • Patent Type: Utility patent for new and useful ferric organic compounds.
  • Patentability Requirements: Must be useful, novel, and nonobvious.
  • Claims: Define the scope of protection and must be clear and supported by the specification.
  • Examination Process: Involves review by a USPTO examiner and potential Office Actions.
  • Scope: Covers specific ferric organic compounds, methods of making them, and their uses.
  • Impact: Contributes to innovation, productivity, and a clearer patent landscape.
