Abstract
Patent information is critical and important object to reflect differences in technology capacity; the paper makes statistical analysis on structural elements of five large-sized oil companies from America and China as collected in Derwent Innovations Index, and compare technical similarities and differences between such companies' patents with visualization tools, by further research on academic classes, Derwent Class Code and co-occurrence of Manual Code. It is shown from the researches that Chinese enterprises is advantaged in growth in number of patents and cooperation rate, but their patents are characterized by poor influence, less relevance and connection between various disciplines, as well as relatively backward development of patented technology. Finally, according to current status of patents of Chinese and American oil companies, the paper proposes a series of recommendations and countermeasures for improvement in patents quality and future expansion in patented technology by Chinese oil companies.
Highlights
The International Energy Agency and CBN Research Institute jointly release a report named as “World Energy Outlook 2013,” which predicts after 2020, China will become the world’s largest oil importing country, and by 2030 China will replace the American as the largest oil consumption country
It is shown by data sourced from World Intellectual Property Organization: Patent information accounts for more than 90% of global output of R and D activities;[1] patent literature has become a major source for obtaining emerging technologies
Chinese Oil Company ranks behind ConocoPhillips in comprehensive strength, but holds more patents than ConocoPhillips, which indicates that Chinese oil companies are trending to catch up American oil companies in technical development
Summary
The paper positions its target objects as 5 Chinese and American companies listed in World Oil Company top 25 as released in Forbes (2012), utilizes Assignee Code AC = (ESSO‐C or CALI‐C or CONO‐C or SNPC‐C or CNPC‐C) as search limit conditions, to obtain 40,428 patents from 1963 to 2012 by Derwent Innovation Index (DII). It makes comprehensive analysis of current status of Chinese companies’ patents, presenting similarities and differences in patent applications between five companies, which is conducted from views of the distribution of years, collaboration, h index, subject categories and DII Class Code. On the base of the conclusions above, the paper proposes correspondent countermeasures and the suggestion of improving the protection of patents and promoting technology innovation of Chinese oil industry
