Summary for Patent: 10,898,575

Title:	Long-acting polymeric delivery systems
Abstract:	Compositions comprised of a delivery vehicle or delivery system and an active agent dispersed within the delivery vehicle or system, wherein the delivery vehicle or system contains a polyorthoester polymer and a polar aprotic solvent. Also disclosed are low viscosity delivery systems for administration of active agents. The low viscosity delivery systems have a polyorthoester polymer, a polar aprotic solvent and a solvent containing a triglyceride viscosity reducing agent. Compositions described include an amide- or anilide-type local anesthetic of the "caine" classification, and a non-steroidal anti-inflammatory drug (NSAID), along with related methods, e.g., for treatment of post-operative pain or for prophylactic treatment of pain. The compositions are suitable for delivery via, e.g., direct application and instillation, intradermal injection, subcutaneous injection, and nerve block (perineural).

Analyzing the Scope and Claims of United States Patent 10,898,575

To conduct a detailed analysis of the scope and claims of a specific patent, such as United States Patent 10,898,575, it is crucial to follow a structured approach. Here’s a step-by-step guide to help you understand and analyze the patent landscape surrounding this patent.

Understanding the Patent Document

Locating the Patent

To begin, you need to locate the patent document. You can use the USPTO's Patent Public Search tool or other patent search databases to find the patent by its number[1].

Reading the Patent Abstract

The abstract provides a brief summary of the invention. This section helps in understanding the overall scope and purpose of the patent.

Claims Section

The claims section is the most critical part of the patent document. It defines the scope of the invention and what is protected by the patent. Claims can be independent or dependent, with dependent claims building upon independent claims[3].

Analyzing the Claims

Identifying Independent and Dependent Claims

Independent claims stand alone and define the invention without reference to other claims. Dependent claims, on the other hand, refer back to and further limit the independent claims.

Understanding Claim Scope Concepts

To analyze the claims effectively, categorize them by scope concepts. This involves grouping claims based on the overarching ideas or technologies they cover. This method helps in identifying gaps or opportunities in the patent coverage[3].

Patent Landscape Analysis

Global Dossier and Patent Family

Use the Global Dossier service to view the patent family for the specific application. This includes all related applications filed at participating IP Offices, along with dossier, classification, and citation data. This helps in understanding the global reach and related patents[1].

Common Citation Document (CCD)

The CCD application consolidates prior art cited by all participating offices for the family members of a patent application. This tool is essential for visualizing search results from multiple offices on a single page, aiding in a comprehensive landscape analysis[1].

Claim Coverage Matrix

Creating a Claim Coverage Matrix

A Claim Coverage Matrix shows which patents and claims are actively protecting your intellectual property and where gaps or opportunities exist. This matrix helps in categorizing patents not only by claims but also by the overarching scope concepts[3].

Using Claim Charts

Utilize ClaimScape® software or similar tools to generate interactive claim charts. These charts can be reviewed by technical experts to determine if a particular scope concept is applicable to a target product or method. This method is quick and accurate, helping to identify gaps in current coverage and highlight future design opportunities[3].

Patent Classification and Technology Areas

International Patent Classification (IPC)

Understand the IPC codes associated with the patent. Patents can be tagged with multiple IPC codes, which help in classifying the technology areas covered by the patent. This classification is crucial for regional economic analysis and understanding the broader technological context[4].

Geographical and Economic Analysis

Geocoding and Location Analysis

Geocoding assigns geographical information to the patent data, allowing for regional economic analysis. This is particularly useful for understanding the impact of the patent in different geographical areas[4].

Economic Sectors

Analyze the patent data by economic sector, which can differ from the inventor's residence. This helps in understanding the economic implications and the sectoral distribution of the patent's impact[4].

Public Search and Resource Centers

USPTO Public Search Facility

Utilize the USPTO Public Search Facility or local Patent and Trademark Resource Centers (PTRCs) for additional resources and trained staff assistance. These facilities provide access to patent and trademark information in various formats[1].

Patent Official Gazette

Browse through the Electronic Official Gazette to see issued patents for the current week, categorized by classification or type of patent. This helps in staying updated with recent patent issuances[1].

Statistical Analysis and Trends

Patent Data Collection and Curation

Use detailed technical documentation and reports, such as those from the NSF, to analyze patterns and trends in patenting activity. This includes county-level data and fractional counts of patents to avoid double counting across sectors and technology areas[4].

Legal and Litigation Aspects

Patent Litigation

Be aware of any ongoing or past litigation related to the patent. For example, patent disputes like the one between Moderna and Pfizer/BioNTech highlight the importance of robust patent protection and the potential for legal battles over intellectual property[5].

Maintaining and Updating Patent Coverage

Regular Updates and Reviews

Regularly update and review the claim charts and coverage matrix as more patents are filed or as new avenues of development are explored. This ensures that the patent landscape remains current and relevant to the company's needs[3].

Key Takeaways

• Comprehensive Search: Use multiple resources like the USPTO Patent Public Search, Global Dossier, and Common Citation Document to gather a complete view of the patent landscape.
• Claim Analysis: Categorize claims by scope concepts and use claim charts to identify gaps and opportunities in patent coverage.
• Geographical and Economic Analysis: Analyze patent data by geographical location and economic sector to understand the broader impact.
• Regular Updates: Keep the patent landscape analysis up-to-date to reflect changes in the company's technology and market.
