Find Relevant Prior Art Search for your Patent Application.

Professional Excellence

Innovation with Quality Focus

You Matter First


Our Prior Art Searches cover global patent and technical literature search to determine the novelty or nonobviousness of your invention. We help you make better IP decisions with our expertise across various technology domains, including Life science, Pharmaceutical, Electrical engineering, Medical devices, Digital Media, Environmental Remediation, Mechanical engineering, Material Sciences, IoT and Big Data, Physics. It’s all about identifying search results that precisely meet client needs; we do this by focusing on relevant keywords for them to be found accurately.

Performing a prior art search helps determine whether an idea has been patented before or if there are any similar inventions out there that might pose a threat to yours. It also helps ensure that no one else will be able to claim ownership over something they didn’t invent themselves! You can perform a basic prior art search yourself using Google Patents or our services at, where we provide professional assistance with search for relevant patents and other forms of prior art, so you don’t have to worry about infringing on anyone else’s intellectual property rights!

As an investor, you must understand IP law(legal rights) —specifically, patent law as it relates to validity and infringement. A patent or a patent application is not just a technical paper but also a legal document. And your patent attorney will help you out throughout the process.

Patent Search

Following are some Patentability Research Services/Resources which provide the relevant prior art.

A patent keyword search is a form of patent search that looks up terms in multiple patent databases to assist you in finding patent applications that are comparable to your invention. By conducting a patent keyword search, you can discover whether your idea can be patented or whether a competing patent already exists.

The site allows you to do a semantic search and to filter the results by the patent office, filing status, active/expired, and date.

Repeat various combinations of keywords until you think you’ve found the relevant existing patents and patent applications. Thus, you are skimming the patents and patent applications that you found. By scanning the first pages of each patent application, you can eliminate most of the records from your search.

The USPTO website is another reasonably user-friendly patent database. By performing a search based on keywords that would logically be within a summary statement of a patent. 

In about 2 minutes, our tool will search the patent database by category (CPC/IPC), classification number, and F-terms to return relevant results for your query! This will save you hours of work and allow you to get started building a product based on existing technology much faster than previously!

With Assignee/Inventor-based search, it doesn’t matter if you’re looking for someone inside your own company or across many companies around the globe. You can find by both assignee and inventor so that you’ll always be able to find who you need; when you need them, will provide you with a list of databases (menu)

Citations are the building blocks of citation analysis, and they have many beneficial uses. Backward citations on patent applications can be studied to find out where an idea was first introduced, while forward citations reflect how important it has been over time for other patents in your field or industry with your results; you can download PDFs of published applications or issued patents.

An NPL is any publicly available material that is not a patent or a pending/expired publication in a patent office. The NPLs assist in identifying key domain competitors and market giants with products similar to your inventions; identifying different application areas of the invention; identifying potential research scholars who can collaborate with you in moving forward with your invention; and identifying any mishaps, such as publishing your invention in a journal without your consent.

Search The Patent Database

The patent databases are a goldmine for inventions and ideas. Your invention is about to change the world, but before you do that, there’s one last thing. Find out if it has been patented.

Google Patents

Google Patents is a patent application indexing search engine. These documents contain the entire collection of granted patents, published itemized specifications for each database that belong in the public domain because their creators made them available after filing them with government offices. They assist in tracking down any information about any product/service ideas backed up not only by citations but also illustrations and are very useful in Basic Prior Art Search.


USPTO search interface

The USPTO’s trademark database (Trademark Electronic Search System, or TESS) is helpful for anyone who wants to check/find prior art if they have registered any marks similar to those already in use. The site can even reveal whether another company has applied for patents on related products or services; this way, you will know what’s up with your competition. In addition, USPTO allows you to research and filter results for USPTO office actions, claims, and responses across a collection of a pending patent, granted patent, and all abandoned applications.

Espacenet search interface

Espacenet is a patent database containing information (complete copies of the documents) on inventions and technological advances. The interface is available in practically every European language, making it simple for users unfamiliar with patent to learn more about the state of innovation and keep up with new developments.


WIPO search interface

WIPO (World Intellectual Property Agency) is an international organization dedicated to promoting the protection of industrial property like inventions, trademarks, and designs as well as copyrighted materials around the world (literary, musical, photographic, and other artistic works). The WIPO offers a free platforms that allows you to obtain information about intellectual property worldwide and find prior art. 

Types of Prior Art Searches

Prior art searches take 4 forms: Novelty, Validity, Clearance, and Landscape searches.

Novelty search

This pre-emptive step (prior art searching) helps inventors assess their chances of obtaining a patent before they spend time, money, and energy on something that might not work out in the end.  

Validity Searches

Validity searches are frequently performed after a patent is issued with the goal of uncovering prior art that the law has disregarded. These are also beneficial for competitors who want to challenge the validity of a patent that has been awarded.

Clearance Search

A Clearance search is an integral part of the patent application process, including receiving, examining, and issuing patents. It assures that no one else has patented your idea before you, saving you time and money on filing fees as well as any future patent infringement or validity lawsuits.

Landscape Search

A landscape search provides a high-level overview of the technology space. It is usually performed to understand how one might tackle an unfamiliar area, such as recent trends in this field. It's also good for finding out what other companies are up against when entering new fields.

    Most frequent questions and answers

    Review for Prior Art Search involves searching publicly available sources to discover whether an invention has been previously described in other references (i.e., prior art) or not. If it has been described in a prior art reference, a later-filed patent application would not be granted as anticipated by the search prior art. In short, if there is a publication date before the filing date of the patent application and that publication describes or consists all aspects of the invention as claimed, the invention will not be considered as novel, and therefore ineligible for patent protection. Besides helping to find out novelty, patentability, prior art searches can generate ideas for research and development (R & R&D).

    Prior art searches are vital because it controls the ability to gain intellectual property (IP) rights over an invention. Suppose the inventor is unable to gain IP rights. In that case, the creation may have a decreased market value and the inventor may be not able to prevent rivals from entering the market or be forced to obtain licenses from the life IP rights holder.

    Except where the inventor is an expert in his field of an invention and has a great understanding of industry trends but without a prior art search, an inventor will be operating in information and will not be able to form an educated opinion about whether the investor can obtain a patent protection on the invention. 

    Not, all prior art disqualifies an invention from being able to receive a patent. Prior art essentially refers to the entire span of human knowledge, and if one effectively differentiated an invention even from a similar one, a patent may be secured.
