Understanding the Scope and Claims of United States Patent 11,291,793: A Comprehensive Analysis
Introduction
When analyzing a patent, it is crucial to delve into its scope, claims, and the broader patent landscape to fully comprehend its implications and validity. This article will provide a detailed analysis of United States Patent 11,291,793, focusing on its claims, the legal framework surrounding it, and the relevant patent landscape.
Patent Overview
United States Patent 11,291,793, though not directly provided in the sources, can be analyzed using general principles of patent law and the context provided by similar cases and patent datasets.
Claims Analysis
Claim Structure
Patent claims are the heart of any patent, defining the scope of the invention. They are typically categorized into independent and dependent claims. Independent claims stand alone and define the invention, while dependent claims refer back to and further limit the independent claims[3].
Claim Validity
The validity of patent claims can be challenged under various grounds, including obviousness-type double patenting (ODP), lack of written description, and obviousness. For instance, in the case of Allergan USA, Inc. v. MSN Laboratories Private Ltd., claims were challenged under ODP and lack of written description. The court reversed the district court's determination that the claims were invalid for ODP and lack of written description, highlighting the importance of careful claim drafting and the nuances of patent law[2].
Obviousness-Type Double Patenting (ODP)
ODP is a doctrine that prevents an inventor from securing a second, later-expiring patent for an invention that is not patentably distinct from an earlier patent. This doctrine is particularly relevant when patents have overlapping claims or when a terminal disclaimer is involved.
Terminal Disclaimers and ODP
A terminal disclaimer is a statement by the patent owner that the patent will expire on the same date as an earlier patent, often used to overcome ODP rejections. The Federal Circuit has held that ODP analyses must consider the adjusted expiration date of the patent, including any patent term adjustments (PTA) or extensions (PTE)[1].
Patent Term Adjustments (PTA) and Extensions (PTE)
PTA and PTE are mechanisms to extend the term of a patent due to delays in the prosecution process or regulatory approvals, respectively.
PTA and ODP
The Board has reasoned that PTA should not extend the term of a patent past the date of a terminal disclaimer. This means that any ODP analysis or determination should be based on the adjusted expiration date of the patent, considering any PTA or PTE granted[1].
Written Description Requirement
The written description requirement under 35 U.S.C. ยง 112 ensures that the patent specification adequately describes the invention claimed. This requirement is crucial for ensuring that the claims are supported by the patent's disclosure.
Case Law
In Allergan USA, Inc. v. MSN Laboratories Private Ltd., the district court's determination that certain claims lacked written description was reversed by the Federal Circuit. This highlights the importance of thorough documentation and clear description in the patent specification to support the claims[2].
Patent Landscape
The patent landscape surrounding a specific patent includes other related patents, patent applications, and the overall technological environment.
Patent Claims Research Dataset
The USPTO's Patent Claims Research Dataset provides detailed information on claims from US patents and patent applications, which can be used to analyze trends and patterns in patent scope and claims. This dataset can help in understanding how claims are structured and validated over time[3].
AI and Patent Eligibility
In the context of AI-related inventions, the USPTO has updated its guidance to clarify the process for determining patent eligibility. This includes evaluating whether a claim integrates a judicial exception into a practical application, ensuring that AI-assisted inventions are evaluated on equal footing with other technologies[4].
Key Takeaways
- Claims Structure: Independent and dependent claims define the scope of the invention.
- ODP: Prevents securing a second, later-expiring patent for an invention not patentably distinct from an earlier patent.
- PTA and PTE: Adjustments and extensions to the patent term due to prosecution delays or regulatory approvals.
- Written Description: Ensures the patent specification adequately describes the invention claimed.
- Patent Landscape: Includes related patents, applications, and the technological environment.
- AI and Patent Eligibility: Focuses on integrating judicial exceptions into practical applications.
FAQs
-
What is Obviousness-Type Double Patenting (ODP)?
- ODP is a doctrine that prevents an inventor from securing a second, later-expiring patent for an invention that is not patentably distinct from an earlier patent.

How do Terminal Disclaimers affect ODP?
- Terminal disclaimers are used to overcome ODP rejections by ensuring that the later patent expires on the same date as the earlier patent.
-
What is the difference between PTA and PTE?
