Summary for Patent: RE41571
Title:Method of providing sustained analgesia with buprenorphine
Abstract:A method of effectively treating pain in humans is achieved by administering buprenorphine in accordance with first order kinetics over an initial three-day dosing interval, such that a maximum plasma concentration from about 20 pg/ml to about 1052 pg/ml is attained, and thereafter maintaining the administration of buprenorphine for at least an additional two-day dosing interval in accordance with substantially zero order kinetics, such that the patients experience analgesia throughout the at least two-day additional dosing interval.

Understanding the Scope and Claims of U.S. Patents: A Detailed Analysis

Introduction

When navigating the complex landscape of U.S. patents, understanding the scope and claims of a patent is crucial for innovators, patent practitioners, and businesses. This article delves into the key aspects of patent scope, claim construction, and recent updates in patent law, using the context of U.S. Patent RE41571 as a reference point.

Patent Scope: An Overview

Patent scope refers to the breadth and depth of protection afforded by a patent. It is a critical factor in determining the patent's value and its potential impact on the market. Research has shown that narrower claims at publication are associated with a higher probability of grant and a shorter examination process compared to broader claims[3].

Metrics for Measuring Patent Scope

Two simple yet effective metrics for measuring patent scope are independent claim length and independent claim count. These metrics have explanatory power for several correlates of patent scope, including patent maintenance payments, forward citations, the breadth of patent classes, and novelty. Studies have validated these measures, indicating that they can predict various outcomes during the patent examination process[3].

Claim Construction and Patent Eligibility

Claim construction is the process of interpreting the meaning and scope of patent claims. Recent updates, such as the 2024 USPTO Guidance Update on AI Patent Eligibility, have refined this process.

Evaluating Practical Applications

The 2024 USPTO Guidance Update emphasizes the importance of evaluating whether a claim integrates a judicial exception into a practical application. This involves assessing additional elements in the claim to determine if they impose meaningful limits on the exception, thereby transforming the claim into patent-eligible subject matter. For example, Claim 2 in the guidance update specifies the use of separated audio components in a real-time speech recognition system, which adds a practical application and makes the claim patent-eligible[1].

AI-Assisted Inventions

The update clarifies that the method of invention development, including the use of AI, does not impact subject matter eligibility. Instead, the focus remains on the claimed invention itself, ensuring that AI-assisted inventions are evaluated on equal footing with other technologies. This distinction is crucial as it ensures that AI’s role as a tool does not exclude inventions from eligibility, provided there is significant human contribution[1].

Incorporation of Recent Case Law

The guidance integrates recent Federal Circuit decisions, providing up-to-date legal standards and interpretations. This integration promotes consistency and clarity in the application of patent eligibility criteria, reflecting the latest judicial thinking. For instance, the guidance includes new examples (Examples 47-49) specifically tailored to AI technologies, illustrating how claims involving specific applications of neural networks can meet the eligibility criteria[1].

Real-World Applications and Patent Eligibility

Highlighting the real-world applications of the claimed method or system is essential for bolstering the argument for patent eligibility. Demonstrating how the abstract idea is applied in a way that provides concrete benefits or solves specific problems in the relevant field is crucial.

Example Analysis

In the context of U.S. Patent RE41571, if the claims involve abstract ideas such as data analysis or mathematical calculations, they must be integrated into a practical application to be patent-eligible. For example, if a claim involves using a mathematical model to manipulate data, it must specify how this data is applied in a way that improves technology or provides a practical application. Merely using the model without a specific application would not meet the criteria for patent eligibility[1].

Patent Examination Process

The patent examination process plays a significant role in shaping the scope of patent claims. Research has shown that the examination process tends to narrow the scope of patent claims in terms of both claim length and claim count. This narrowing is more significant when the duration of examination is longer[3].

Restriction Requirements

During the examination process, restriction requirements can be imposed if the claims cover multiple independent and distinct inventions. For instance, in the case of Gilbert P. Hyatt, the Patent and Trademark Office (PTO) imposed a restriction requirement due to the applicant's failure to disclose claims to a separate invention and the significant delay in filing these claims. This highlights the importance of timely and complete disclosure of all relevant claims[2].

Data and Analytics in Patent Scope

The use of data and analytics is becoming increasingly important in understanding patent scope. The USPTO's Patent Claims Research Dataset provides detailed information on claims from U.S. patents granted between 1976 and 2014 and U.S. patent applications published between 2001 and 2014. This dataset includes claim-level statistics and document-level statistics, offering insights into patent scope measurements[5].

Key Takeaways

  • Patent Scope Metrics: Independent claim length and independent claim count are effective metrics for measuring patent scope.
  • Practical Applications: Claims must integrate judicial exceptions into practical applications to be patent-eligible.
  • AI-Assisted Inventions: The use of AI in invention development does not impact subject matter eligibility, provided there is significant human contribution.
  • Real-World Applications: Highlighting real-world applications of claimed methods or systems is crucial for patent eligibility.
  • Examination Process: The patent examination process tends to narrow the scope of patent claims.
  • Data Analytics: Utilizing datasets like the USPTO's Patent Claims Research Dataset can provide valuable insights into patent scope.
