Non-patent literature (NPL) is an invaluable asset in intellectual property research, offering insights beyond patent documents.
Non-patent literature, or NPL, refers to a vast array of documents and publications that, while not part of the formal patent literature, are crucial for comprehensive patent searches and informed decision-making in intellectual property (IP) fields. Understanding what NPL encompasses, its functions, and how it integrates into patent research is fundamental for IP professionals, researchers, and inventors alike.

What Is Non-Patent Literature?
Non-patent literature is a diverse range of publications and documents not included in patent filings but essential in IP research.
Some examples of non-patent literature include:
- Scientific and Technical Journals: These provide detailed research findings and developments in specific fields, crucial for understanding the latest technological trends.
- Conference Proceedings: Early research findings are often published here, offering a glimpse into emerging technologies and innovations.
- Government and Institutional Reports: These documents offer authoritative information on various scientific and technical topics, often used for in-depth analysis.
- Theses and Dissertations: Academic papers often contain cutting-edge research and novel ideas, providing a fresh perspective on various subjects.
- Books and Trade Publications: They offer comprehensive overviews and in-depth discussions on established and emerging technologies.
Non-patent literature is also used in the context of patent examinations and intellectual property disputes. This type of literature is often leveraged by patent examiners or legal professionals to assess the novelty and non-obviousness of a patent application. By comparing the proposed invention against existing knowledge in the field, as documented in non-patent literature, an examiner can determine whether the invention is truly innovative or just an incremental change over what's already known.
In the regular course of work, non-patent literature may appear in various forms and from diverse sources, such as technical standards and specifications, market analysis and industry reports, patents and technical libraries, online databases and search engines, and so on. Understanding and utilizing non-patent literature is essential for anyone involved in research and development, patent filing, and intellectual property law, as it provides a comprehensive background against which new inventions and ideas can be assessed and developed.
How Does Non-Patent Literature Work?
NPL complements patent documents by providing additional context, historical background, and technical details, enriching the patent research process.
Non-patent literature (NPL) is typically added during the patent examination process, where patent examiners reference it to assess the novelty and inventiveness of a patent application. Additionally, NPL can be brought in during patent litigation for defending or challenging the validity of a patent. Researchers and inventors also review NPL before filing a patent to understand the current state of technology.
NPL is found in diverse sources, including scientific and technical journals, conference proceedings, academic theses, government and institutional reports, books, trade publications, and online databases like Google Scholar and IEEE Xplore. These sources provide a comprehensive background against which new inventions are assessed.
Non-patent literature works by enhancing a patent with:
- Additional context: NPL provides details that patents typically don’t cover, such as theoretical underpinnings, alternative approaches, and broader implications of the technology. For instance, academic articles might discuss the underlying principles of a technology in greater depth than a patent.
- Historical background: NPL can trace the evolution of a technology, offering insights into its development over time. This includes previous attempts, incremental advancements, and the broader narrative of the field's progress. For example, older scientific papers or books might document early versions or concepts related to the technology.
Consider a fictional patent for a new widget based on research from 1995, using government data and mentioned in a non-fiction book by the creator 10 years ago. In this case:
- The government data might provide empirical evidence or foundational information that underpins the technology.
- The non-fiction book could offer personal insights into the invention process, theoretical discussions, or reflections on the technology's potential impact.
- Previous research from 1995 might be cited to show the historical development and initial conceptualization of the widget.
All these elements of NPL provide a richer, more comprehensive understanding of the patent, its novelty, and its significance in its field.
How Does USPTO Use Non-Patent Literature?
The United States Patent and Trademark Office (USPTO) utilizes NPL for a more comprehensive review of patent applications, ensuring a thorough understanding of the technological field concerned.
The USPTO reviews a patent in the following order:
- Review of the Main Patent Application: The USPTO first closely examines the main patent application. This includes an analysis of the claimed invention, its specifications, and drawings. The goal here is to understand the nature of the invention and its proposed application.
- Examination of Non-Patent Literature: After reviewing the main patent, the examiner delves into relevant NPL. This step is crucial for understanding the existing state of technology and scientific knowledge related to the patent application. NPL sources such as scientific journals, technical papers, and other publications provide context and background, helping the examiner assess whether the invention is novel and non-obvious. By comparing the patent application with existing literature, the examiner can determine if the claimed invention has already been disclosed or if it represents a genuine advancement in the field.
- Consideration of the Patent Author's Bio: The examiner may also review the background of the patent author. This includes their previous work, qualifications, and any relevant publications. This step can offer insights into the author's expertise and potential contributions to the field, although it is less critical than the analysis of the patent application and NPL.
- Assessment and Decision Making: Integrating information from the patent application, NPL, and the author's bio, the USPTO makes a decision regarding the patent's validity. This decision is based on criteria like novelty, non-obviousness, and usefulness. The USPTO may also issue queries or requests for clarification to the applicant during this process.
How to Search Non-Patent Literature
Searching for non-patent literature (NPL) is a vital step for researchers, inventors, and patent professionals. It aids in gaining a comprehensive understanding of existing knowledge in a specific field, ensuring that new innovations or patent applications are novel and non-obvious. Accessing NPL can also provide valuable insights into the development and trajectory of technology, which is crucial for strategic planning and competitive analysis.
The best ways to search for non-patent literature include:
- Utilizing Academic Databases: Platforms such as JSTOR, Google Scholar, and IEEE Xplore provide access to a wealth of scientific journals and technical papers. These databases are essential for finding peer-reviewed articles and detailed research relevant to your field of interest.
- Specialized Search Engines: Tools like Google Patents are not only for searching patents but also for finding NPL that is cited in or related to specific patents or technologies. These platforms can link directly to NPL sources, making them a valuable resource.
- Conducting Targeted Queries: To improve the efficiency and accuracy of your searches, use targeted queries. Employ relevant keywords and Boolean operators (like AND, OR, NOT) to refine your search. This approach helps in narrowing down results to the most relevant documents.
