Why is Non-Patent Literature Vital for Patent Research?

 


Scholarly publications have always been the first choice for keeping track of ground-breaking research in academia. These kinds of sources such as scientific journals are generally labeled as non-patent literature (NPL) in the context of IP. NPL is used as a valuable source for competitive intelligence and prior art for invalidity or novelty searches. Any NPL that is closely related to the subject matter covered in a patent application is cited within the document by the inventor or examiner.

For example, the inventor or examiner cites any NPL that is closely linked to the subject matter in a patent application. Several competitive intelligence workflows also use NPL citations to gain insights on the extent of a patenting entity’s research.

Kinds of NPL and their sources

NPL can be broadly categorised into non-journal references and journal references.

Non-journal references

Reference books, magazines,

social media, YouTube, blogs,

announcements, company newsletters, books, conference proceedings, patent related documents.

Sources: Company websites, Wiley, Science Direct, Google Scholar, Derwent Innovation Index, Google Patents, lens.org, social media platforms, IEEE, etc.

Journal references

Scientific publications in journals

Sources: Google Scholar, PubMed, AGRICOLA, Springer, Agris, Science Direct, Wiley Online Library, DOAJ, Research Gate, MDPI,

Web of Science, IEEE, etc.

 What role does NPL play in IP processes?

A)    Invalidation search or novelty search

In addition to patents, NPL can also be used as valid prior art for invalidity or novelty searches. NPL is published before patents (which take 12-24 months from the filing date to publication), so it should be included in your prior art searches particularly for projects with high future investments, where it’s necessary to restrict expenditure on inventions that may not obtain patent protection.



PatSeer Explorer is an IP intelligence software that searches across patents and journals simultaneously to ensure that no relevant record is missed. Use its patent visualization tools to quickly study a topic of your interest. Access prominent science and engineering databases via the platform’s single integrated search interface.

B) Competitive intelligence & technology analysis

NPL holds a lot of potential for competitive intelligence activities. Prominent CI activities include:

  • Finding open innovation or licensing partners – Literature research can help in finding the right partner for open innovation or licensing. If a company has already started work on a technology, they can use literature references to find partners that are working in the same industry to accelerate the development of the technology and launch it in the market before others do so.
  • Accelerating the innovation cycle – A thorough study of NPL along with patents helps accelerate the innovation cycle from ideation to commercialization. As universities initially publish only a fraction of their research in patents, no technology landscape or problem-solution analysis is complete without looking at non-patent literature.

A Year into Europe's Unitary Patent System: Progress and Challenges

Image
Since its launch on June 1, 2023, the Unitary Patent System has aimed to simplify processes, reduce costs, and unify legal protection across participating EU countries. In its first year, over 27,500 Unitary Patents were registered, covering 80% of the EU's GDP. Germany and France led adoption, though the absence of key economies like Spain and Poland shows harmonization is still a work in progress.   The system's Unified Patent Court (UPC) has quickly become a central venue for patent litigation, handling over 500 cases in diverse tech sectors. Businesses appreciate the faster resolution times and streamline legal processes, though some SMEs remain cautious due to perceived cost risks. Meanwhile, traditional litigation has declined, raising questions about local court roles in the evolving ecosystem.   Cost savings are significant maintaining a Unitary Patent for 10 years costs less than €5,000 compared to nearly €29,000 under the old system. However, challenges persist, ...

Patent or Trade Secret? The IP Dilemma Every Innovator Faces

Image
Should you patent your innovation or keep it under wraps? It’s a question that has shaped the strategies of industry giants like Apple, Coca-Cola, and Google. Patents offer strong legal protection — but require public disclosure and hefty costs. Trade secrets, on the other hand, are free to keep — but risky to lose. Choosing the right path isn’t just a legal decision — it’s a business strategy. From tech to pharmaceuticals, and from manufacturing to software, different industries lean on different IP tactics to gain a competitive edge. In this quick-read guide, I break down: Key differences between patents and trade secrets Industry-specific trends and best practices Global legal impacts (like GDPR and the Defend Trade Secrets Act) Strategic questions to help you decide what’s best for your business Sometimes the smartest move is a hybrid approach. 🧠 Want to dig deeper into how companies like Tesla and Pfizer handle this decision? 👉  Read the full guide here  — How to Decide...

IP Benchmarking: How Well Do You Know Your IP Portfolio?

Image
IP benchmarking gives you a detailed understanding of the strengths, weaknesses, competitive positioning, and risks related to your patent portfolio. It can help you identify areas vulnerable to competition as well as competitive advantage. IP benchmarking should be conducted periodically  (e.g. annually) to guarantee that the IP strategy is in line with the business strategy. Subject matter experts, senior management, and IP professionals should participate in this exercise. The figure given below demonstrates the process for IP benchmarking: Additionally, IP benchmarking activities can be categorized into 2 types: externally focused benchmarking and internally focused benchmarking.  1.        Internally focused IP benchmarking This kind of benchmarking assesses the level of protection given by your IP portfolio. Map your  patents against your current technologies and products to ascertain if their unique characteristics are adequately protect...
