Core Technologies

Westport's extensive intellectual property (IP) portfolio gives the Westport group of companies a competitive advantage. Our expertise includes: injectors (combined gaseous fuel/pilot fuel injectors and monofuel injectors), combustion chamber geometry and control strategies, engine fuel systems, cryogenic storage and delivery (cryogenic tanks and cryogenic pumps), and compressors.

This chart shows only a portion of our full IP portfolio*—natural gas injection / engine / combustion technology—and illustrates our strength and leadership in this market.

• Company Strength [vertical axis]
  Each company's revenue as a percentage of total revenue of all of companies, plus % locations (companies with more locations are generally stronger), plus % litigation (companies that litigate are generally stronger).
• IP Strength [horizontal axis]
  Number of searchable* patents per company as a % of total patents found (companies with more patents generally have stronger patent portfolios), plus the % of classifications (more classifications means more subject matters are covered), plus the % of citations (the number of times a patent has been cited by other patents, and the number of patents that a patent itself cites). More patent citations generally means a patent is more relevant to the analyzed technology space. If a patent doesn't cite other patents, or is itself not cited, then it's more likely an obscure, non-mainstream, and less valuable technology.
• Number of Patents [circle size]
  Number of searchable* patents per company.

* Based on the patent search results of publicly available data within the International Patent Classification F02, meeting the search term criteria: one of ("engine" or "combustion" or "injector" or "injection valve") and ("natural gas" or "methane" or "gaseous fuel") and not ("fuel cell" or "turbine"). This chart includes issued or granted patents from: Australia, Brazil, Canada, China, European Patent Office Grants, France, Germany, India, Italy, Japan, Poland, Russia, Spain, UK, USA, USSR, and pending published patent applications from: the European Patent Office, USA, and the World Intellectual Property Office.
