Prior art searches take 4 forms: Novelty, Validity, Clearance, and Landscape searches.
If a patentee intentionally misled the Patent Office (PTO), the patent may be unenforceable, nullifying all infringement claims. A thorough prior art search and patent validity analysis can help identify such risks early and safeguard your IP strategy.
You can have a patent reviewed by the PTAB, and if found invalid, it proves no infringement occurred. With Quality Insights, evaluate prior art, patent strength, and invalidity risk to make informed IP strategy decisions.
If a patentee intentionally misled the PTO, the patent may be deemed unenforceable, nullifying all related patent infringement claims. Conducting a thorough prior art search and patent validity analysis helps identify such risks and protect your IP strategy.
Request a review by the Patent Trial and Appeal Board (PTAB)—if a patent is found invalid, it confirms no infringement occurred. With Quality Insights, analyze prior art, patent strength, and invalidity risk to make informed IP strategy decisions.
Here are some Patentability Research services and resources that deliver comprehensive results for your prior art search, helping identify relevant references and support informed patentability assessments.
A patent keyword search is a crucial part of a prior art search that scans multiple patent databases for relevant terms to identify patents or applications similar to your invention. Conducting a patent keyword search helps determine the patentability of your idea and reveals whether competing patents already exist, enabling informed IP strategy and reducing patent infringement risk.
In just a few minutes, our tool performs a prior art search across patent databases using CPC/IPC codes, classification numbers, and F-terms to deliver the most relevant results for your query. This saves hours of manual work and enables you to quickly assess existing technologies, evaluate patentability, and accelerate product development with confidence.
With assignee/inventor-based search, our prior art search tool lets you locate patents and applications whether you’re searching within your own company or across global organizations. You can filter results by assignee or inventor, ensuring you quickly identify relevant innovators and technologies. The tool also provides access to a comprehensive list of patent databases, supporting thorough novelty search, patentability search, and IP due diligence for faster and more accurate decision-making.
Citations are key components of citation analysis and play a vital role in prior art search and patentability assessment. Backward citations on patent applications help trace where an idea was first introduced, while forward citations indicate the influence and relevance of that invention over time within your industry or technology field. Leveraging citation analysis enhances novelty search, patent strength evaluation, and IP due diligence, providing deeper insights for informed patent strategy decisions.
An NPL is any publicly available material that is not a patent or a pending/expired patent publication. Incorporating NPL in your prior art search helps identify key competitors, market leaders, and products similar to your invention. It also uncovers alternative application areas of your technology, supporting thorough novelty search, patentability assessment, and IP strategy planning.
If a component is supplied solely to enable another party to infringe a patent, and it has no other legitimate use, it may be considered contributory infringement. Conducting a thorough prior art search and patent validity analysis can help identify such risks and strengthen your IP strategy.
A prior art search is a detailed investigation of existing patents, publications, and non-patent literature to determine whether an invention is novel and patentable. At PatentsKart, our experts conduct comprehensive searches to assess novelty, patentability, and freedom to operate (FTO).
A thorough prior art search helps identify existing technologies, minimize patent infringement risk, and strengthen your IP strategy. It also supports patentability assessments and improves the chances of a successful patent application.
Prior art includes existing patents, patent applications, and non-patent literature (NPL) such as scientific publications, technical journals, and conference papers. PatentsKart also analyzes forward and backward citations to gauge the influence and relevance of prior inventions.
Yes. By identifying existing patents and publications early, a prior art search can help businesses avoid costly patent infringement claims and make informed decisions regarding product development and market entry.
