Summary for Patent: 11,278,623
Title:Non-aqueous patch
Abstract: Non-aqueous patches comprising lidocaine, which is not dissolved and is present in a crystalline state, have poor permeability to the skin. Therefore, non-aqueous patches have a high concentration of lidocaine. It is pointed out that lidocaine has an adverse effect on the heart. Prolonged use of a high concentration of lidocaine causes side effects, such as shock, rubor, and irritating sensation. External preparations comprising more than 5 mass % of lidocaine are designated as powerful drugs, and cannot be used as household (nonprescription) medicine. Provided is a non-aqueous patch that is effective to relieve muscle pain, the non-aqueous patch comprising lidocaine and/or its reactant, and a dissolving agent composed of an organic acid and a polyalcohol, which are contained in a base.

Understanding the Scope and Claims of United States Patent 11,278,623: A Comprehensive Analysis

Introduction

Patent 11,278,623, like any other patent, is a complex document that outlines the invention, its claims, and the scope of protection it offers. To fully grasp the significance and implications of this patent, it is crucial to delve into its various components and the broader patent landscape.

The U.S. Patent and Trademark Office (USPTO)

The USPTO is the agency responsible for granting U.S. patents and registering trademarks. Understanding the role of the USPTO is essential in analyzing any patent, as it sets the standards and guidelines for patent eligibility and the patenting process[2].

Patent Claims and Scope

Patent claims define the scope of the invention and are critical in determining what is protected by the patent. The USPTO provides detailed datasets and research on patent claims, which can help in understanding the scope and complexity of patent claims, including those of Patent 11,278,623[3].

Claim Structure

  • Independent Claims: These claims stand alone and define the invention without reference to other claims.
  • Dependent Claims: These claims refer back to and further limit the scope of an independent claim.
  • Method Claims: These claims describe a process or method of achieving a particular result.
  • Apparatus Claims: These claims describe a physical device or system.

Claim Analysis

To analyze the claims of Patent 11,278,623, one must identify the independent and dependent claims, understand the relationships between them, and determine the scope of protection each claim provides. This involves a detailed review of the claim language, the specification, and any drawings or diagrams included in the patent.

Patent Eligibility

The eligibility of a patent is determined by whether the invention falls within the categories of patentable subject matter as defined by 35 U.S.C. ยง 101. Recent updates from the USPTO, such as the 2024 guidance on AI patents, provide insights into how to draft claims that are more likely to be considered patent-eligible. For example, claims must go beyond mere abstract ideas or routine data processing steps to be eligible[4].

Abstract Ideas and Practical Applications

  • Claims that involve only abstract ideas or insignificant extra-solution activities are generally not patent-eligible.
  • Claims that include practical applications and provide tangible benefits, such as improving the accuracy of real-time speech recognition systems, are more likely to be considered patent-eligible.

Obviousness-Type Double Patenting (ODP)

ODP is a doctrine that prevents the same inventor from obtaining multiple patents for the same invention. This is particularly relevant when dealing with continuation-in-part patents, as seen in the case of In re Cellect LLC, where multiple patents were challenged for ODP due to their derivation from the same priority application[1].

Impact on Patent Term

  • Patents that are subject to ODP can have their terms adjusted or even invalidated if they are found to be obvious variants of earlier patents.
  • The Patent Term Adjustment (PTA) can also play a role, as delays during prosecution can extend the patent term, but this must be carefully managed to avoid ODP issues.

Small Claims Patent Court

The concept of a small claims patent court has been explored as a potential solution to make patent litigation more accessible and less costly for smaller entities. This initiative involves studying the feasibility and structure of such a court, including legal, policy, and practical considerations[5].

Implications for Patent Holders

  • A small claims patent court could provide a more streamlined and cost-effective way for patent holders to enforce their rights.
  • It could also impact the strategy for drafting and prosecuting patents, especially for smaller inventors and businesses.

Industry Expert Insights

Industry experts and legal practitioners play a crucial role in shaping the patent landscape. For example, the consultative group advising the Administrative Conference of the United States (ACUS) on the small claims patent court study includes experts like Andrei Iancu, former Undersecretary of Commerce for IP and Director of the USPTO, and David Kappos, former Undersecretary of Commerce and Director of the USPTO[5].

Practical Advice

  • Experts advise that patent claims should be crafted to provide meaningful, tangible benefits and not merely abstract ideas.
  • The use of detailed eligibility analysis, as provided in the USPTO's AI patent guidance, can help in drafting claims that are more likely to be patent-eligible.

Statistical Insights

The USPTO's Patent Claims Research Dataset provides valuable statistical insights into patent claims and scope. This dataset includes claim-level statistics and document-level statistics, which can help in understanding trends and patterns in patent claims over time[3].

Trends in Patent Scope

  • The dataset shows that the scope of patents can vary widely depending on the field of technology and the complexity of the claims.
  • Analyzing these statistics can provide insights into how to draft claims that are more likely to be granted and enforced.

Case Studies and Examples

Real-world examples and case studies are essential in understanding the practical implications of patent claims and scope. For instance, the In re Cellect LLC case highlights the importance of managing ODP and PTA to avoid patent term issues[1].

Practical Applications

  • The case of In re Cellect LLC demonstrates how multiple patents derived from the same priority application can lead to ODP issues.
  • This example underscores the need for careful patent strategy and management to avoid such complications.

Key Takeaways

  • Patent Claims: The claims define the scope of the invention and are critical in determining what is protected by the patent.
  • Patent Eligibility: Claims must go beyond abstract ideas and provide practical applications to be considered patent-eligible.
  • ODP: Managing ODP is crucial to avoid patent term issues, especially for continuation-in-part patents.
  • Small Claims Patent Court: This initiative could provide a more accessible and cost-effective way for patent holders to enforce their rights.
  • Statistical Insights: The USPTO's Patent Claims Research Dataset offers valuable insights into trends and patterns in patent claims.
