How to generate a Patent Landscape

When you work in a particular technology area it is often useful to understand who else is working on the same technologies and who may be patenting or inventing aspects of the technology.  A patent landscape is the name given to a study of who holds these patents and the detailed understanding of trends in terms of numbers of patents granted; regions where the most patents are filed; understanding prior art and where potential gaps are for working on improvements or new features.  In addition, links between assignees and inventors (in particular any evidence of universities or research centres working with companies) can be very useful for finding collaborators or third parties who may be interested in joint research and development.

There are many organisations that provide this sort of information for a price and will provide a nice visual overview but when you are not really sure exactly what you are looking for it is much better to try out a few searches yourself and explore the landscape so that you know what you are up against and how complicated the landscape might be.

One organisation that provides this type of information together with some analysis is the World Intellectual Property Organization (WIPO) and, best of all, it is free!  The system is called PATENTSCOPE and is very simple to use.  It can be found at https://patentscope.wipo.int/search/en/search.jsf

Let’s now try and get a quick overview of the Internet of Things.  This is a really exciting new technology area where everyday items can connect via the internet to one another and interact in useful ways.

Open the link and in the simple search box type in the phrase “internet of things” using quotes to show that it is a phrase that we want to search on.  Rather than searching just on the Front Page select Any Field as shown below:

Click on search and the results immediately show.

You can see that there were 8,230 patent documents found from all the databases (by default we searched all the English language databases).  If you click on the Analysis bar it will open up a window where you can see at a glance which countries are filing patents, how many, who the top inventors and applicants are and what the timeline trend looks like.  You can also see the data graphically if you choose the various options in the window.  Some examples are shown below:

The items in the table are all clickable so you can drill down to examine patents from any of the inventors or companies very quickly, or you could examine who first started filing in 2010.

The pie chart can be quite useful to see a breakdown of the main patent classification codes which give some idea of the technology areas covered.  An explanation of IPC and CPC codes can be found here: http://worldwide.espacenet.com/classification?locale=en_EP

One problem with the data is that it is not standardised, for example you can see that Samsung appears under different names in the table so that you would need to add these together to get a proper feel for how many of the patent documents are owned by Samsung.  If you do this you find it is over 700, nearly 10% of the total.  Across all the patents you can see that the last 2 years accounts for around 75% of the total number.

If you wanted to explore the data in more detail you are allowed to download the results into an excel spreadsheet (10,000 records is the limit), however, you need to be logged in with a free account to be able to do this.  From the spreadsheet you can unravel a lot more detail about other companies and inventors filing, start to explore trends over time and look at granted patents.  In this dataset for example there are only 2.5% of the US patents actually granted, clear evidence that this is an emerging technology and there is quite a race to get the technology protected by patent rights.

I hope this brief overview has given you some idea of how to get a quick insight into the patent landscape of a particular technology area.  As always, do contact me if you have any questions or want a detailed landscape of your own technology area.
