V. Filing activity at CIPO Patent Landscape Report - Shale Oil and Gas

The following section focuses on shale oil and gas patents filed with CIPO. In total, 284 patents were included in the analysis. To generate the dataset for this analysis, a query similar to the one used in Thomson Innovation was employed; however, in this case it was done in CIPO's patents database and included bilingual terms.

The trend in shale oil and gas patent applications filed with CIPO, shown in Figure 16, is similar to those seen previously. That is, it shows one of significant growth, but on a much smaller scale. Overall, the number of patents in the Canadian dataset by priority year has been increasing since 2000. The high degree of variation from year to year is likely due to the small sample size. With respect to how filings are made in Canada, 74% of patents are filed through the Patent Cooperation Treaty (PCT). This is in line with the ratio of PCT found in total filings with CIPO. We also found that 75% of applications in Canada were filed first in the USA, 5% in China, and a further 5% in Japan.

The top applicant for filings related to shale oil and gas is Halliburton Energy Service Inc. Exxon Mobile Corp. is second, with approximately half the number of filings of the top applicant. Of note is that Chinese and Japanese companies are not major filers in Canada, while American companies are.

Figure 17 illustrates a bar chart for the top applicant filings at CIPO.

As depicted in Figure 18, the top three applicants have been actively filing with CIPO since 2000, whereas others are either more selective in the patents they file with CIPO or simply not actively patenting. From the information collected in the worldwide analysis, we know some of these companies are actively patenting, and are simply not filing in Canada.

Figure 19 shows a bar chart for the top inventors that file at CIPO.

This patent landscape map is helpful in identifying technological areas where patenting activity is prominent in Canada. It is possible that because most of the world's oil sands reserves are found predominantly in Canada and Venezuela, certain inventions are only worth patenting in these countries since there is not much use for these patents elsewhere. This may also explain why firms filing in the exploration area are more likely to file in Canada than those filing in the development and production areas.

Description of Figure 20

The figure provides a visual representation of technological areas in the shale oil and gas field where patenting activity is prominent in Canada. Thomson Innovation's ThemeScape mapping tool was utilized for this purpose. ThemeScape uses term frequency (keywords from patent filings' title and abstract) and other algorithms to cluster documents based on shared language. Snow-capped peaks represent the highest concentration of patents with the following keywords: “Hydrotreating”, “Catalyst”, “Peak”, “Slag”, “Fly Ash”, “Ash”, “Bottom”, “Heater” and “Circulation.”
