The Value of Hidden Citations in Patent Evaluation: Why the blind spot and how to uncover it

Most patent professionals recognize that a raw count of the number of forward citations to a patent can be an indicator of a patent’s value. However, a mere count is insufficient because decoding the citations to support meaningful decisions is still a challenge. To further complicate matters, important and meaningful citations are virtually always underreported making them unavailable to patent analysts for consideration. This article reveals new data that may render traditional citation analysis inadequate, and discusses the who, what, and when of each citation as an important consideration when attempting to derive value from careful examination of the complete forward citation record.

New method uses patent data to estimate a technology’s future rate of improvement

The team devised an equation incorporating a patent set’s average forward citation and average publication date, and calculated the rate of improvement for each technology domain. Their results matched closely with the rates determined through the more labor-intensive approach of finding numerous historical performance data points for each technology. Among the 28 domains analyzed, the researchers found the fastest-developing technologies include optical and wireless communications, 3-D printing, and MRI technology, while domains such as batteries, wind turbines, and combustion engines appear to be improving at slower rates.
