United States Patent 11,779,552: A Detailed Analysis of Scope, Claims, and Patent Landscape

Introduction

The United States Patent 11,779,552, titled "Method of treating cancer using selective estrogen receptor modulators," is a significant patent in the field of oncology, particularly for the treatment of estrogen receptor-positive cancers. Here, we will delve into the scope, claims, and the broader patent landscape surrounding this invention.

Background and Context

Estrogen receptor-positive (ER+) cancers, such as certain types of breast and brain cancers, are influenced by the presence of estrogen. Selective estrogen receptor modulators (SERMs) are compounds that can either mimic or block the effects of estrogen in different tissues, making them valuable in cancer treatment[1].

Scope of the Patent

This patent focuses on methods for treating subjects suffering from estrogen receptor-positive cancer, specifically in the brain, using SERMs. The scope includes the administration of specific compounds that target the estrogen receptor, thereby inhibiting the growth of cancer cells.

Key Components

  • Compounds: The patent specifies certain SERMs, such as RAD1901, which are designed to interact with the estrogen receptor in a way that inhibits cancer cell proliferation.
  • Administration: The methods described involve the administration of these compounds in a manner that targets brain tumors effectively.
  • Therapeutic Outcomes: The patent aims to achieve improved therapeutic outcomes by reducing the growth of ER+ cancer cells in the brain.

Claims of the Patent

The claims of the patent are crucial as they define the legal boundaries of the invention.

Independent Claims

  • The patent includes independent claims that describe the method of treating ER+ cancer using specific SERMs.
  • These claims outline the steps involved in administering the compounds and the expected therapeutic effects.

Dependent Claims

  • Dependent claims further detail the specific conditions under which the method is applied, such as the dosage and frequency of administration.
  • These claims also cover variations of the method, including combinations with other treatments.

Patent Landscape

Understanding the patent landscape is essential for assessing the novelty, non-obviousness, and potential impact of the invention.

Technology Area

  • This patent falls under the technology area of pharmaceuticals and biotechnology, specifically within the subclass of cancer treatments.
  • According to the USPTO, patents in this area are classified under the World Intellectual Property Organization (WIPO) classification system, which helps in analyzing trends and comparing global inventive activities[4].

Competing Patents

  • The patent landscape in cancer treatment is highly competitive, with numerous patents covering various aspects of cancer therapy.
  • Other patents may cover different types of SERMs or alternative methods of treating ER+ cancers, which could potentially overlap or conflict with the claims of this patent.

Global Trends

  • The number of patents in the pharmaceutical and biotechnology sectors has been increasing, reflecting the growing focus on innovative treatments for various diseases, including cancer.
  • Data from the USPTO shows that electrical and mechanical engineering patents, while dominant, do not overshadow the significant advancements in pharmaceuticals and biotechnology[4].

Analyzing Claims Coverage

To fully understand the protection and opportunities provided by this patent, it is crucial to analyze the claims coverage.

Claim Coverage Matrix

  • A Claim Coverage Matrix can help identify which patents and claims are actively protecting the intellectual property related to SERMs and cancer treatment.
  • This matrix categorizes claims by scope concepts, allowing for a comprehensive analysis of the patent landscape and identification of gaps or opportunities[3].

Scope Concepts

  • The scope concepts related to this patent would include the specific mechanisms of action of SERMs, the types of cancers targeted, and the methods of administration.
  • These concepts help in filtering, searching, and analyzing large numbers of patent claims to determine their applicability and value[3].

Evaluating Patent Value

The value of the patent claims can be evaluated based on their current and potential future impact.

High-Value Claims

  • Claims that are directly applicable to current treatments and have a significant therapeutic impact would be considered high-value.
  • For example, claims covering the use of RAD1901 in treating ER+ brain cancers would be highly valuable given the specificity and efficacy of the treatment.

Medium-Value Claims

  • Claims that indicate potential future directions, such as variations in dosage or combination therapies, would be considered medium-value.
  • These claims provide a roadmap for future research and development, enhancing the overall value of the patent.

Low-Value Claims

  • Claims that are not currently applicable or are deemed not worth maintaining would be considered low-value.
  • These claims might be redundant or overlapping with other patents, reducing their significance in the overall patent portfolio[3].

Illustrative Statistics

  • In 2018, the USPTO awarded 309,000 utility patents, with a significant portion in the pharmaceutical and biotechnology sectors[4].
  • The trend shows an increasing focus on innovative treatments, with electrical and mechanical engineering patents also seeing substantial growth, though not directly related to this patent.

Expert Insights

Industry experts emphasize the importance of targeted therapies in cancer treatment. For instance:

"Targeted therapies, such as those using SERMs, offer a more precise approach to treating cancers, reducing side effects and improving patient outcomes"[1].
