Summary for Patent: 11,701,352
Title:Process for preparing aripiprazole oral soluble film
Abstract:The present invention is directed to an aripiprazole oral soluble film and a preparation method thereof. The aripiprazole oral soluble film comprises 10-60% w/w of aripiprazole in a crystalline state and 30-95% w/w of one or more film-forming materials, wherein 90% of the aripiprazole particles have a size of ≤14.3 μm and are uniformly blended in the film without visible undispersed particles. The aripiprazole oral soluble film has excellent bioavailability, uniformity, stability, and palatability. The oral soluble film preparation is prepared by first grinding aripiprazole particles to have desired small particle sizes, then blending the aripiprazole particles with film forming materials in an aqueous solution to a uniform suspension, defoaming the suspension, and coating the suspension on a substrate and drying it to form a film.

Detailed Analysis of the Scope and Claims of United States Patent 11,701,352

Introduction

Patent analysis is a crucial step for businesses and innovators to understand the intellectual property landscape, identify potential risks, and uncover opportunities. This article will delve into the details of United States Patent 11,701,352, examining its scope, claims, and the broader patent landscape in which it resides.

Understanding the Patent System

Before diving into the specifics of the patent, it's essential to understand the framework within which patents are granted and managed. The U.S. Patent and Trademark Office (USPTO) is the agency responsible for granting U.S. patents and registering trademarks[5].

Patent Landscape Analysis

A patent landscape analysis involves reviewing, organizing, and extracting value from extensive patent search results. This process is vital for identifying key players, technologies, and trends in a particular field. Here are the key steps involved in such an analysis:

  • Identify the Technology Area: Define the specific technology or innovation area relevant to the patent.
  • Conduct a Comprehensive Search: Use databases such as the USPTO's Patent Public Search, PATENTSCOPE, and the Cooperative Patent Classification (CPC) database to search for relevant patents and applications[4][3].
  • Analyze the Search Results: Employ computer software and human intelligence to review and organize the search results.
  • Extract Value: Identify critical and relevant patent information that can inform business and technical strategies.
  • Draw Conclusions: Use the analyzed data to make actionable decisions, such as reducing redundant research, accelerating time to commercialization, and protecting against defensive litigation[3].

Scope of United States Patent 11,701,352

To analyze the scope of this patent, we need to consider the following elements:

Invention Description

The patent description outlines the invention's purpose, its components, and how it operates. This section is crucial for understanding what the patent covers and what it does not.

Claims

The claims section is the most critical part of a patent as it defines the legal boundaries of the invention. Claims must be clear, concise, and supported by the description. Here, we would look at the independent and dependent claims to understand the scope of protection.

Prior Art

Understanding the prior art cited in the patent helps in identifying how the invention differs from existing technologies. This is essential for assessing the novelty and non-obviousness of the invention.

Claims Analysis

The claims of a patent are its lifeblood, as they define what is protected by the patent. Here are some key aspects to consider:

Independent Claims

Independent claims stand alone and define the broadest scope of the invention. They typically include the essential features of the invention.

Dependent Claims

Dependent claims build upon the independent claims and add additional features or limitations. These claims are narrower in scope but can provide additional protection.

Claim Construction

Claim construction is a legal process where the meaning of the claims is interpreted. This is often a point of contention in patent litigation, as the interpretation can significantly impact the scope of protection[2].

Patent Landscape

The patent landscape surrounding United States Patent 11,701,352 involves several key elements:

Competitors and Key Players

Identifying other patents and patent holders in the same technology area can reveal competitors and potential collaborators. This helps in understanding the market dynamics and potential licensing or litigation risks.

Technology Trends

Analyzing the patent landscape can highlight trends in technology development. This includes identifying areas of intense innovation and potential future directions.

Geographical Distribution

Understanding where patents are being filed and granted can provide insights into global market strategies and regional innovation hubs.

Example: Patent Search System

The USPTO's Patent Search System – Specialized Search (PSS-SS) is an example of a system that supports detailed patent searches. This system provides access to highly specialized data, including biosequences, chemical structures, and foreign patent data, which are crucial for conducting thorough patent landscape analyses[1].

Legal Considerations

Patent validity and enforceability are subject to various legal considerations, including:

Obviousness-Type Double Patenting

This doctrine prevents an inventor from securing multiple patents for the same invention, ensuring that the public benefits from the invention after the original patent term expires. This is particularly relevant when analyzing the validity of claims in relation to prior art and other patents[2].

Invalidity Challenges

Claims can be challenged for invalidity based on grounds such as obviousness, lack of novelty, or insufficient disclosure. These challenges must be proven by clear and convincing evidence[2].

Key Takeaways

  • Comprehensive Search: Conduct a thorough search using multiple databases to identify relevant patents and applications.
  • Claims Analysis: Carefully review the claims to understand the scope of protection.
  • Prior Art: Analyze prior art to assess the novelty and non-obviousness of the invention.
  • Legal Considerations: Be aware of legal doctrines such as obviousness-type double patenting and invalidity challenges.
  • Market Insights: Use the patent landscape analysis to gain insights into market trends, competitors, and potential opportunities.

FAQs
