Understanding the Scope and Claims of United States Patent 10,335,451
Introduction
United States Patent 10,335,451, titled "Method of treating low blood pressure," is a patent that outlines a specific medical treatment method. To fully comprehend the implications and boundaries of this patent, it is crucial to delve into its scope, claims, and the broader patent landscape.
Patent Overview
The patent in question, US10335451B2, was granted for a method of treating various conditions related to low blood pressure, including septic shock, acute kidney injury, severe hypotension, cardiac arrest, and refractory hypotension. The method involves the administration of specific compounds to stabilize blood pressure in patients suffering from these conditions[4].
Scope of the Patent
The scope of a patent is defined by its claims, which are the legally binding descriptions of the invention. For US10335451B2, the scope includes:
Independent Claims
Independent claims are those that stand alone and define the invention without reference to other claims. In this patent, the independent claims focus on the method of administering angiotensin II or other related compounds to treat low blood pressure conditions. These claims are critical as they define the core of the invention and what is protected under the patent[4].
Dependent Claims
Dependent claims build upon the independent claims and provide additional details or limitations. For example, dependent claims might specify the dosage, timing, or specific patient groups for the treatment method. These claims help to narrow down the scope and ensure that the patent protection is not overly broad[4].
Claim Language and Metrics
The language and structure of the claims are vital in determining the patent's scope. Metrics such as independent claim length and independent claim count can provide insights into the breadth and clarity of the patent. Research has shown that narrower claims, as measured by these metrics, are often associated with a higher probability of grant and a shorter examination process[3].
Determining Inventorship
Inventorship is a critical aspect of patent law, and it is defined by the conception of the idea or subject matter of the patent claims. For US10335451B2, the inventors listed are those who conceived the method of treating low blood pressure using the specified compounds. It is essential to identify the true and only inventors to ensure the patent's validity, as incorrect or deceptive inventorship can lead to the patent being declared invalid[1].
Reduction to Practice
While conception is the key factor in determining inventorship, the reduction to practice is also an important step. This involves making a working example of the claimed invention. However, individuals who only contribute to the reduction to practice by exercising ordinary skill in the art are not considered inventors[1].
Patent Landscape
The patent landscape for medical treatments, particularly those related to blood pressure, is complex and highly competitive. Patents like US10335451B2 must navigate through existing prior art and ensure that their claims are novel, non-obvious, and useful. The patent office examines these claims rigorously to prevent overly broad patents that could stifle innovation[3].
Prior Art and Priority Dates
The patent application for US10335451B2 has multiple priority dates and related applications, indicating a series of improvements and refinements to the original invention. The earliest priority date is December 16, 2009, which is crucial for determining the patent's validity and its relationship with prior art[4].
Legal and Practical Considerations
The enforcement and validity of a patent like US10335451B2 depend on several legal and practical considerations. For instance, the correct identification of inventors and the absence of deceptive intent are essential. Any errors in inventorship can be corrected, but deceptive intent can render the patent unenforceable[1].
Future Implications and Small Claims Courts
The ongoing discussions about establishing a small claims patent court highlight the need for more accessible and efficient dispute resolution mechanisms for patent holders. This could impact how patents like US10335451B2 are enforced and litigated in the future, potentially making it easier for smaller entities to protect their intellectual property[5].
Key Takeaways
- Scope Defined by Claims: The patent's scope is primarily defined by its independent and dependent claims.
- Inventorship: Correct identification of inventors is crucial for the patent's validity.
- Reduction to Practice: While important, reduction to practice does not qualify someone as an inventor unless they contributed to the conception.
- Patent Landscape: The patent must navigate through prior art and ensure novelty, non-obviousness, and utility.
- Legal Considerations: Correct inventorship and absence of deceptive intent are vital for the patent's enforceability.
FAQs

- The main subject matter is a method for treating low blood pressure conditions such as septic shock, acute kidney injury, severe hypotension, cardiac arrest, and refractory hypotension.
-
How is inventorship determined in patent law?
- Inventorship is determined by identifying those who conceived the idea or subject matter of the patent claims. Conception is the formation of a definite and permanent idea of the complete and operative invention[1].
-
What are the consequences of incorrect inventorship?
- Incorrect inventorship, especially with deceptive intent, can render the patent invalid and unenforceable[1].
-
How do independent and dependent claims differ?
- Independent claims stand alone and define the invention without reference to other claims, while dependent claims build upon the independent claims and provide additional details or limitations[4].
-
Why is the patent landscape important for US10335451B2?
- The patent landscape is crucial because it ensures that the patent is novel, non-obvious, and useful, and that it does not infringe on existing prior art[3].
