United States Patent 8,672,898: A Detailed Analysis of Scope and Claims
Introduction
The United States Patent 8,672,898, titled "Automatic injection device with reset feature," is a significant innovation in the field of medical devices, particularly for the administration of repetitive injections. This patent, granted to address the needs of patients requiring multiple doses of medication, introduces a sophisticated design that enhances user convenience and safety.
Background and Prior Art
Before delving into the specifics of US Patent 8,672,898, it is essential to understand the context and prior art in this field. Previous patents, such as U.S. Pat. No. 5,626,566, described pen-shaped syringes for repetitive injections. These devices, however, had limitations, including the need for a release mechanism to reset the dose and a separate manual actuating mechanism to express the medicine[1][4].
Key Components of the Patent
Dose Setting Mechanism
The patent describes an advanced dose setting mechanism that allows for the setting and adjustment of doses in both directions. This mechanism simultaneously sets a given dose and stores the energy necessary for driving the drive member to expel the medicine. Unlike earlier devices, this mechanism can reduce or cancel a set dose by reversing the input motion, typically by rotating a setting member backwardly[1][4].
Drive Member and Coupling
The device includes a drive member and a dose setting mechanism that work in tandem. The dose setting mechanism allows for the adjustment of the dose without the need for an additional release mechanism. This is achieved through a unidirectional coupling between the piston drive member and the dosing member, which can be released by reversing the input motion[1][4].
User Convenience and Safety
The design of this automatic injection device prioritizes user convenience and safety. By allowing the dose to be set and reset without additional mechanisms, it simplifies the process for patients who need to administer multiple doses. This feature reduces the risk of errors and makes the device more user-friendly.
Patent Claims
Definition and Importance
Patent claims are the most critical part of a patent application as they define the exclusive right granted to the patent applicant. According to 35 USC 112, the applicant must particularly point out and distinctly claim the subject matter of the invention[5].
Structure and Format
The claims in US Patent 8,672,898 are structured to comply with the requirements outlined in 37 CFR 1.75. These claims must be clear, concise, and distinct to ensure that the scope of the invention is well-defined and protected.
Independent and Dependent Claims
The patent includes both independent and dependent claims. Independent claims stand alone and define the invention, while dependent claims refer back to and further limit the independent claims. This structure helps in defining the scope of the invention and its various embodiments[5].
Patent Scope and Metrics
Measuring Patent Scope
The scope of a patent is a crucial aspect of patent quality. Metrics such as independent claim length and independent claim count can be used to measure patent scope. These metrics help in assessing the breadth and clarity of the patent claims[3].
Application to US Patent 8,672,898
In the context of US Patent 8,672,898, the independent claims are detailed and specific, ensuring that the invention is clearly defined. The use of clear and concise language in the claims helps in avoiding ambiguity and ensures that the patent scope is well-defined.
Economic and Innovation Impact
Patent Quality and Innovation
The quality of patents, including their scope and clarity, has a significant impact on innovation. Patents with clear and well-defined claims can encourage innovation by providing clear boundaries and incentives for further research and development. In contrast, overly broad or unclear patents can lead to increased licensing and litigation costs, which can hinder innovation[3].
Market Impact
The automatic injection device with a reset feature has the potential to significantly impact the medical device market. By offering a more convenient and safe way to administer medication, it can improve patient outcomes and reduce healthcare costs. This innovation can also drive further research and development in the field of medical devices.
