AMBERCITE Ai : a totally unique patent search tool                  

A patent search engine that cuts to the chase

Find patents others miss with Ambercite Ai

When you rely solely on a conventional patent search database, you depend heavily on keyword and semantic association. We all know, however, that this search process can be notoriously inexact, laborious and time consuming. By contrast Ambercite Ai uses AI-assisted algorithms which find the most similar patents to one or more starting patents. Results are ranked by similarity, and searches are extremely quick and easy, thanks to a simple and intuitive interface.

Save time, money and aggravation

 Along with a number of our clients, we’ve actually bench marked Ambercite Ai’s algorithms against the best semantic patent search engines on the market. As a result, we’re now convinced that it’s the best patent search tool available for finding similar patents. Our unique family to family patent analysis isn’t weakened by the limitations of inconsistent language and terminology inherent in other approaches. Ambercite Ai delivers you fast, cost-effective and intuitive patent searches that pinpoint similar patents missed by others – all in less than one second.

Plus Ambercite Ai now has a smart review interface that allows you to review illustrative images and abstracts – easily and efficiently.

Many of clients using our patent search software to provide them with instant and easy to review results for questions around invalidity and patentability - so avoiding the delay and cost of outsourcing. With Ambercite, all you need to run a patent search is one or more known patents in any area to find a whole lot more - regardless of the language, keywords and class codes that they use. 

And... even if you do decide to outsource, Ambercite can help you provide a tighter more relevant brief to the search department.

In any case:  No search is complete without Ambercite

No matter how you do your patent searching,  you should insist that before any conclusions are made,  that they  are tested using Ambercite.  Even if  Ambercite  doesn't find  any patents  that will change  the findings of your conventional search,  at least you will have the piece of mind, that no stone has been left un-turned !! 


Example of Ambercite Ai in use - and its unique ability to ZOOM INTO UNCITED prior art that mattered in litigation

Consider the case of EASTMAN KODAK CO., ET AL, vs CTP INNOVATIONS, LLC,, IPR2014-00788, published on 13th January 2017. In this case, a number of claims of US6738155 were invalided in the light of Dorfman, WO199808176, and some non-patent literature. The patent claimed remote printing of PDF images.

Running the prior art query shown below on patent US6738155 returned 250 prior art documents, which can be reviewed via this interactive link found here.

But there is also the option to add a simple keyword filter.

While all patents were potentially relevant, we can then apply keyword filtering to reduced this data set. A key feature of the US6738155 patent was the printing of PDF documents. For this reason a keyword filter was applied to the result set so that only prior art patent families that referred to "PDF" in either the title or abstract were retained.

By limiting the results in this way, only one patent was left to review - being WO199808176, the knockout Dorfman patent, which was firstly published in February 1998. Yet this patent had not been previously cited against US6738155 - the examiner had not found this patent in their conventional patent examination search.

This, in two simple steps, Ambercite was able to uncover the previously uncited prior art patent that helped to invalidate US6738155. This truly is an AI approach to patent searching - that works.

Augmented Searching - unique searching workflows that combine apply your expertise with the Ambercite algorithms to provide an unfair advantage

Ambercite is great at finding similar and highly reelvant patents to the patents you have already found. But what if you could easily use these patents to find even more relevant patents - and efficiently review the new findings without having to go over old ground? Wouldn’t that be great?

Well, you can - check out the video case study below:

There are a number of products and firms out there that also offer patent databases.

So why should you choose also Ambercite products or services?


We identify what are likely to be the most similar and most important patents close to the patents that you are interested in, using advanced methods based on our AI algorithms and our database of over 106 million patents and 175 million patent citations. This saves you time and money otherwise lost on reading low value patent documents.  

Abstract, representative image and smart review features can then allow you to hone into the patents that you are looking for. This reduces the risk of missing key patents.


We provide intuitive and interactive graphics. This helps make patent searching more interesting! Visuals, rather than log lists of data, are more intuitive to many people and can improve your patent searching productivity. It is thought that our brains can process visuals 60,000 times faster than text.


All our products rely on objective and automated algorithms analyzing what can be hundreds of thousands of data points for one similarity assessment. Even better, our AI algorithms analyse over 150 millions independent examiner or applicant patent citations, removing the need for the risky assumptions of classification systems or subject matter text analysis. Better and more comprehensive data means better outcomes.


By focusing on being the best patent citation based patent search tools, our products are designed to complement your existing search databases, and so provide a second and what may be a unique opinion.
