Understanding Patent Scope
The scope of a patent defines the boundaries of what is protected by the patent. It is determined by the claims, which are the legally binding descriptions of the invention.
Claims Analysis
The claims section of a patent is the most critical part, as it outlines what the inventor considers to be their invention. For US Patent 11,135,293, the claims would typically include:
- Independent Claims: These are the broadest claims that define the invention.
- Dependent Claims: These claims are narrower and build upon the independent claims, often adding specific details or limitations[3].
To analyze the claims, one would need to review the patent document in detail, focusing on the language used and the specific elements described.
Patent Claims Research Dataset
For a deeper analysis, the USPTO's Patent Claims Research Dataset can be invaluable. This dataset provides 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 understanding the scope and breadth of the claims in US Patent 11,135,293[3].
Patent Landscape Analysis
Analyzing the patent landscape involves looking at related patents, prior art, and the broader intellectual property environment.
Prior Art and Citation Analysis
Prior art refers to any evidence that a particular invention was already known or publicly available before the patent application was filed. Tools like the Common Citation Document (CCD) and the Patent Public Search tool can help identify prior art cited by various patent offices. This is crucial for understanding how US Patent 11,135,293 fits into the existing body of knowledge in photodynamic therapy[1].
International Patent Offices
To see if similar inventions have been patented abroad, one can search databases provided by international intellectual property offices such as the European Patent Office (EPO), Japan Patent Office (JPO), and the World Intellectual Property Organization (WIPO). These databases often provide machine translations and full-text searches of international patent applications[1].
PatentsView Database
The PatentsView database offers comprehensive data on U.S. patents, including granted patents and published applications. This database can be used to identify related patent applications, citations, and assignee information, providing a broader view of the patent landscape surrounding US Patent 11,135,293[4].
Search Tools and Resources
Several tools and resources are available to aid in the analysis of US Patent 11,135,293:
Patent Public Search
The Patent Public Search tool is a powerful resource that replaced legacy search tools like PubEast and PubWest. It provides enhanced access to prior art and allows users to search through a modern interface[1].
Global Dossier
The Global Dossier service allows users to access the file histories of related applications from participating IP offices. This can be useful for seeing the patent family for a specific application and understanding the global context of the invention[1].
Patent and Trademark Resource Centers (PTRCs)
Local PTRCs offer training in patent search techniques and maintain local search resources, which can be beneficial for conducting a thorough analysis of the patent landscape[1].
Key Takeaways
