Summary for Patent: 9,216,150
Title:pH dependent carriers for targeted release of pharmaceuticals along the gastrointestinal tract, compositions therefrom, and making and using same
Abstract: Novel drug carriers capable of targeted and/or pH dependent release of biologically active agents into selected pH environments including the gastrointestinal (GI), ophthalmic, urinary, or reproductive tracts. Unexpectedly, carriers including free fatty acids (FFA) are able to deliver biologically active agents to various pH environments. Such targeted delivery is tailorable and useful for active agents that are: (a) injurious to the upper GI tract (esophagus, stomach, and duodenum), (b) acid labile, (c) impermeable/insoluble compounds in GI fluids, (d) susceptible to first pass metabolism, and/or (e) cause stomach irritation, upset, or dyspepsia.

United States Patent 9,216,150: A Detailed Analysis of Scope, Claims, and Patent Landscape

Introduction

United States Patent 9,216,150, hereafter referred to as the '150 patent, is a significant intellectual property asset in the pharmaceutical sector. This patent, like many others, involves complex legal, technical, and strategic considerations. Here, we will delve into the scope, claims, and the broader patent landscape surrounding this patent.

Background of the Patent

The '150 patent is associated with a specific pharmaceutical invention, likely related to a drug or a method of treatment. To understand its significance, it is crucial to identify the inventors, the assignees, and the date of issuance. Typically, this information can be found in the patent document itself or through patent search databases such as those provided by the USPTO[4].

Scope of the Patent

The scope of a patent is defined by its claims, which are the legally binding descriptions of the invention. The claims outline what the inventor considers to be the novel and non-obvious aspects of the invention. For the '150 patent, the scope would include the specific compounds, methods of manufacture, or methods of use that are protected.

Claim Structure

Patent claims are structured in a hierarchical manner, with independent claims standing alone and dependent claims referring back to other claims. The '150 patent would likely have a combination of independent and dependent claims, each contributing to the overall scope of protection[3].

Claim Analysis

To analyze the claims of the '150 patent, one would need to examine each claim individually, looking at the language used and the specific elements described. This involves identifying the key features of the invention and how they are distinguished from prior art. For example, if the patent pertains to a pharmaceutical compound, the claims might specify the chemical structure, synthesis method, or therapeutic use.

Patent Claims and Written Description

The validity of patent claims can be challenged on several grounds, including lack of written description and enablement under 35 U.S.C. ยง 112. The written description requirement ensures that the patent specification adequately describes the invention claimed. In cases like Allergan USA, Inc. v. MSN Laboratories Private Ltd., courts have scrutinized whether the asserted claims are supported by the written description in the patent specification[2].

Patent Expiration and Term Adjustment

Patents have a limited term, typically 20 years from the earliest filing date, subject to adjustments for delays in prosecution (Patent Term Adjustment) and extensions for regulatory review (Patent Term Extension). Understanding the expiration date of the '150 patent is crucial for assessing its remaining life and potential impact on the market[2].

Patent Landscape

The patent landscape surrounding the '150 patent includes other related patents, both from the same assignee and from competitors. This landscape can be analyzed using tools like the Global Dossier, which provides access to the file histories of related applications from participating IP offices[4].

Related Patents and Continuations

The '150 patent may be part of a larger patent family, including continuations, divisionals, and continuations-in-part. These related patents can extend the scope of protection and delay the expiration of the overall patent portfolio. For instance, in the case of Allergan USA, Inc. v. MSN Laboratories Private Ltd., multiple patents with a common priority date were involved, each with its own expiration dates and claims[2].

International Patent Protection

To fully understand the patent landscape, it is essential to look beyond U.S. patents. International patent databases such as the European Patent Office's esp@cenet, the Japan Patent Office, and WIPO's PATENTSCOPE can provide insights into global protection for the same or similar inventions[4].

Strategic Implications

The '150 patent's scope and claims have significant strategic implications for the assignee and competitors. Here are a few key considerations:

Market Exclusivity

The patent provides market exclusivity for the protected invention, allowing the assignee to prevent others from making, using, or selling the invention without permission. This exclusivity can be a powerful tool for maintaining market share and revenue.

Licensing and Collaboration

The patent can be licensed to other companies, generating revenue through royalties. It can also serve as a bargaining chip in collaborative agreements or mergers and acquisitions.

Litigation and Enforcement

The validity and enforceability of the '150 patent are critical. Any challenges to the patent's validity, such as those based on obviousness-type double patenting or lack of written description, can significantly impact its value and the assignee's ability to enforce it[2].

Tools and Resources for Patent Analysis

Several tools and resources are available for analyzing patents like the '150 patent:

USPTO Databases

The USPTO provides various databases, including the Patent Public Search tool, which offers enhanced access to prior art and patent documents[4].

Global Dossier

The Global Dossier service allows users to access the file histories of related applications from participating IP offices, providing a comprehensive view of the patent family[4].

Patent Claims Research Dataset

The USPTO's Patent Claims Research Dataset offers detailed information on claims from U.S. patents and applications, which can be used to analyze claim structures and trends[3].

Key Takeaways

  • Scope and Claims: The '150 patent's scope is defined by its claims, which must be carefully analyzed to understand the protected invention.
  • Patent Landscape: The patent is part of a broader landscape that includes related patents, international protection, and strategic implications.
  • Expiration and Term Adjustment: Understanding the patent's expiration date and any term adjustments is crucial for assessing its remaining life.
  • Strategic Implications: The patent provides market exclusivity, can be licensed, and serves as a tool for litigation and enforcement.
