IV. Canadian activity worldwide Patent Landscape Report - Shale Oil and Gas

Understanding the contribution of Canadian companies to the patenting activity community is important. The following section takes a more in-depth look at the Canadian applicants. Table 2 below provides a summary of the Canadian corporate applicants within the shale oil and gas subset.

Similar to Figure 1, Figure 12 depicts an upward trend in patent filings. The high degree of variation from year to year is due to the low level of filings. However, filings are trending upwards overall.

Figure 14 is a timeline for the filings of top Canadian applicants. Each year with a filing is represented by a blue square that links the applicant to the year.

Figure 15 shows the priority country split for the top Canadian applicants. As expected, the top applicants in the Canadian subset mostly claim priority in the USA, with about 55% of all priority filings going there first. Flo-Dynamics Systems Inc. and Imperial Oil Resources Limited file all of their patents in Canada first. Approximately 35% of all Canadian filings have a Canadian priority.
