Co-patenting Network of Top 100 Inventors in Cancer-Related Fields

The USPTO has developed a new dataset to describe patents and patent applications in cancer-related fields, in support of the US Cancer Moonshot.  By harnessing the power of patent data, and accelerating the process for protecting the intellectual property that lead to cancer research breakthroughs, the USPTO is standing up and doing its part to help bring potentially life-saving treatments to patients, faster.

The data in the below chart via a downloadable Excel file

The USPTO Cancer Moonshot Patent Data consists of 269,353 patent documents (published patent applications and granted patents) ranging from 1976 to 2016.  USPTO is sharing this dataset with researchers and policy makers, so they might gain insight into innovations in cancer-related research and development.  

PatentsView is a patent data dissemination platform that uses advanced algorithms to identify inventors and their organizations and locations across 40 years of US patent data.  The PatentsView team used the Cancer Moonshot Patent Data to identify all of the inventors on cancer-related granted patents in the PatentsView database.  They further transformed the data to describe the connections between inventors who appear on the same patents (co-inventors).  

The PatentsView team then developed an interactive network graph to visualize the collaborations among the worldwide leading innovators in cancer research.  This network visualization presents data on the top 100 inventors, ranked by the number of patents, and their first-degree co-inventors (3,918 in total).  These top 100 inventors are named on 6,533 total cancer-related patents.

How to Use the Visual:

This is a social network chart implemented in Tableau Public.  Each node in the network represents an inventor on a cancer-related patent.  Edges (lines) between two nodes indicate a co-patenting collaboration between the two inventors. Edge color (grayscale) represents the total number of patents on which the two inventors have collaborated, across the dataset.  The size of an inventor node corresponds to their total number of patents.  The color of the node indicates the predominant technology field of that inventor’s patents.  Technology fields are based on the World Intellectual Property Organization (WIPO) categories and are listed in the figure legend.

Highlighting and Accessing the Data:

Hover over a node to see that inventor’s name (last, first), their worldwide rank in patenting in cancer-related fields, the total patent count on which that rank is based, the number of inventors with whom they have co-invented, their predominant patent technology field (WIPO), and their last known location (i.e. country, city) listed in the PatentsView database. Hover over an edge between nodes to view summary data about the collaboration between two inventors - their names (last, first) and the number of patents they invented together.

To access the data, click on a node, wait for a menu to appear, and click on the “column” icon in the top right. You can view and export the source data about a given inventor or co-inventor collaboration.

Interaction:

Apply the top 100 (In/Out) filter in order to explore PatentsView data on the top 100 inventors only, their co-inventors only, or all inventors in the dataset (both groups).  You can filter the top 100 inventor network by country or major technology field, using the checkboxes to the right of the visual.   Drag and move the network by selecting the cursor from the tool menu within the map, underneath the zoom in and out buttons.  Select a specific zoom area using the lasso tool.
