Materials – IP scenario analysis

,

A technology scenario analysis has been performed through the utilization of Derwent Innovation [1]. Derwent Innovation is an application that provides access to the most trusted global patent data, the Derwent World Patents Index (DWPI)[2] and scientific literature.

The analysis has been conducted through the definition of a query, specific for the thematic area, based on the respective IPC[3] codes. In particular, the thematic area of Materials for Additive Manufacturing corresponds to the IPC B33Y 70/00, as depicted in the scheme below.

The time interval considered during the search is between 2008 and 2018. However, 2018 has been excluded from the trend graphs due to the very partial results.

In the following graph total published patents per year are reported.

A strong increase in patent applications has been registered, with a steady linear growth in the period under analysis.

Main application country codes are reported in the following graph; international code (WO) applications are 943, while European code (EP) applications are 630, and are not reported on the map.

China is the most populated country code, followed by United States, international applications (WO), Japan and European (EP) applications.

Main assignees or applicants are reported in the following graph.

The list is led by a series of large companies active in the field of printing technologies and, more in general, information technologies, namely Hewlett-Packard (HP), based in United States, Ricoh CO. from Japan, and Xerox Corporation, also from US. Other company reported in the list active in the same market segments is Seiko Epson Corporation, form Japan, holding the seventh position.

The fourth player reported in the list is Stratasys, another US company strictly focused on 3D printing technologies. Graphene Platform Corporation engages in research, development, manufacturing and sales of nano-inprint devices and ultra precision matching devices. It is based in US with a large R&D centre in Japan.

3D Systems Inc. is a US based company, producing and selling systems for 3D printing. The last two players emerging from the present analysis, namely United Technologies Corporation, from US, and Saudi Basic Industries Corporation (SABIC), public company from Saudi Arabia, are large and diversified manufacturing companies, active in a number of different fields including technologies related to Additive Manufacturing.

Following figure reports the distribution of IPC (International Patent Classification) codes for the patents in scope. The table below, the definitions.

The following map was draft utilizing the proprietary Themescape tool of the Derwent Innovation suite. Themescape performs a semantic analysis on the titles and abstract of patents and groups patents on the basis of top recurrent words. “Hills” represent a concentration of patents in correspondence of common keywords. Each point represents a patent of the dataset. Analysing the map is it possible to note some returning topics in correspondence of peaks.

In the following slideshow are reported:

  1. The map of recurrent topics automatically generated by the Themescape tool, on the basis of a semantic analysis of title and abstracts of papers;
  2. The map of recurrent topicsreporting the positioning of the Top 5 players, giving indication on the main topic of patenting activity.
