“…Pegels and Thirumurthy [17] show that cycle time is negatively correlated with profitability -that is, shorter cycle times increase firm profitability. Additional studies establish cycle time as a valuable indicator related to progress and innovative activity [18,19]. Extension of this concept into literature studies would suggest that shorter cycle times, or shorter reference ages, might be correlated with higher performing or more innovative work in the scientific literature.…”

This paper introduces a new method for evaluating national publication activities. This new indicator, thought leadership, captures whether the nation is a thought leader (building on the more recently cited literature for that field) or follower (building on the older cited literature for that field). Publication data for 2003 are used to illustrate which nations tend to build on the more recent discoveries in chemistry and clinical medicine. Implications for national and laboratory policy are discussed.

“…However, originality of patents is not such a discriminative measure in the teeth of strong interaction and fusion in an ICT industry, and excluded. We calculated the longevity, the rate of obsolescence per year, by using TCT (technology cycle time) in Kayal and Waters (1999). Next, the generality, the range of influence, is estimated separately over industries and ICT clusters.…”

“…The technology strength index (TSI) is a customary index of the quantitative and qualitative technological capability of an applicant. TSI is the number of patents an applicant has obtained multiplied by CII (Kayal and Waters 1999). If a company has a higher TSI than its competitors, the company is more powerful in that technology area.…”

Identifying rapidly evolving technological trends for R&D planning using SAO-based semantic patent networks

Patents constitute an up-to-date source of competitive intelligence in technological development; thus, patent analysis has been a vital tool for identifying technological trends. Patent citation analysis is easy to use, but fundamentally has two main limitations: (1) new patents tend to be less cited than old ones and may miss citations to contemporary patents; (2) citation-based analysis cannot be used for patents in databases which do not require citations. Naturally, citation-based analysis tends to underestimate the importance of new patents and may not work in rapidly-evolving industries in which technology life-cycles are shortening and new inventions are increasingly patented worldwide. As a remedy, this paper proposes a patent network based on semantic patent analysis using subject-action-object (SAO) structures. SAO structures represent the explicit relationships among components used in a patent, and are considered to represent key concepts of the patent or the expertise of the inventor. Based on the internal similarities between patents, the patent network provides the up-to-date status of a given technology. Furthermore, this paper suggests new indices to identify the technological importance of patents, the characteristics of patent clusters, and the technological capabilities of competitors. The proposed method is illustrated using patents related to synthesis of carbon nanotubes. We expect that the proposed procedure and analysis will be incorporated into technology planning processes to assist experts such as researchers and R&D policy makers in rapidly-evolving industries.
