Summary for Patent: 9,539,333
Title:Sustained release polymer
Abstract: A polymer and a method for its preparation are provided. The polymer comprises poly(lactide), poly(lactide/glycolide) or poly(lactic acid/glycolic acid) segments bonded by ester linkages to both ends of an alkanediol core unit. The polymer is for use in a controlled release formulation for a medicament, preferably leuprolide acetate. The controlled release formulation is administered to a patient as a subcutaneous depot of a flowable composition comprising the polymer, a biocompatible solvent, and the medicament. Controlled release formulations comprising the polymer release leuprolide for treatment of prostate cancer patients over periods of 3-6 months.

Analyzing the Scope and Claims of United States Patent 9,539,333

Introduction

Understanding the scope and claims of a patent is crucial for inventors, patent holders, and those interested in the intellectual property landscape. This article will delve into the details of United States Patent 9,539,333, exploring its claims, scope, and the broader patent landscape it inhabits.

Patent Overview

United States Patent 9,539,333, hereafter referred to as the '333 patent, was granted by the United States Patent and Trademark Office (USPTO). To analyze this patent, one must first identify its core subject matter, claims, and the technological field it pertains to.

Subject Matter

The subject matter of the '333 patent can be determined by reviewing its abstract and the detailed description provided in the patent document. This step is essential as it sets the foundation for understanding the invention's purpose and its place within the broader technological landscape.

Claims Analysis

Independent and Dependent Claims

Patent claims are the heart of any patent, defining the scope of protection granted to the inventor. The '333 patent will include both independent and dependent claims. Independent claims stand alone and define the invention in its broadest terms, while dependent claims build upon the independent claims, often narrowing the scope or adding specific details[5].

Claim Construction

Claim construction involves interpreting the language of the claims to determine their scope. This process is critical in patent litigation and during the examination process at the USPTO. The claims must be clear and definite to avoid ambiguity and ensure that the invention is properly protected[5].

Scope of the Patent

The scope of the '333 patent is defined by its claims and the specifications provided in the patent document. This includes:

  • Invention Disclosure: The detailed description of the invention, including how it is made and used.
  • Drawings and Figures: Visual representations that help illustrate the invention.
  • Background of the Invention: Context about the problem the invention solves and the prior art.

Patent Family and Global Dossier

The '333 patent may be part of a larger patent family, which includes related applications filed in various jurisdictions. The Global Dossier service provided by the USPTO allows users to view the file histories of related applications from participating IP Offices, including the IP5 Offices (the USPTO, the European Patent Office, the Japan Patent Office, the Korean Intellectual Property Office, and the State Intellectual Property Office of China)[1].

Public Search and Access

To conduct a thorough analysis, one can use the USPTO Public Search Facility or online resources. The Public Search Facility in Alexandria, VA, offers access to patent and trademark information in various formats, including online, microfilm, and print. Additionally, the USPTO website provides tools like the Patent Assignment Search and the Publication Site for Issued and Published Sequences (PSIPS) for detailed searches[1].

Economic and Statistical Analysis

For a deeper understanding, one can utilize datasets such as the Patent Claims Research Dataset provided by the USPTO. This dataset contains detailed information on claims from US patents granted between 1976 and 2014 and US patent applications published between 2001 and 2014. It includes claim-level statistics and document-level statistics, which can help in analyzing the scope and impact of the '333 patent within the broader patent landscape[3].

Legal and Regulatory Considerations

Inventorship

Determining the true and only inventors is a critical aspect of patent law. The '333 patent must list the correct inventors, as defined by US patent law, which requires the identification of each person who conceived the idea or ideas of the patent claims[5].

Obviousness and Double Patenting

The patent must also pass the tests of obviousness and double patenting. The Court of Appeals for the Federal Circuit has addressed these issues extensively, and any analysis of the '333 patent must consider whether it meets these legal standards. For instance, the case law on obviousness and double patenting, such as the decisions in Merck & Co. v. Hi-Tech Pharmacal Co. and In re Cellect, provides guidance on how these issues are evaluated[4].

Impact on the Market

The '333 patent's impact on the market can be assessed by looking at its technological significance, the industry it pertains to, and any licensing or litigation activities surrounding it. This involves analyzing how the patent affects competition, innovation, and consumer choices within its field.

Key Takeaways

  • Claims Analysis: Understanding the independent and dependent claims is crucial for defining the scope of protection.
  • Scope and Subject Matter: The patent's subject matter and detailed description define its scope and place within the technological landscape.
  • Global Dossier: Utilizing the Global Dossier can provide insights into related applications and the broader patent family.
  • Legal Considerations: Ensuring correct inventorship and compliance with obviousness and double patenting standards is vital.
  • Market Impact: Assessing the patent's technological significance and its effects on the market is essential for understanding its overall value.
