Patent landscapes are used in competitive benchmarking to identify the major applicants or patent owners in a given technology field.
A conventional ranking may include “poor value” patents, many of which may have never been practiced or have even been abandoned: the more patents of this kind an applicant or patent owner has, the higher the possibility of overestimating its technological strength.
Apart from these false-positive issues, there could also be false-negative issues, wherein the major high-value patent applicants or patent owners end up being overlooked simply because buried in the overwhelmingly large number of patents.
Using the Patent Value Rankings to analyze patent landscape charts can help in this scenario: filtering out D-ranked patents from the original landscape, in fact, is a way to address the false-positive issues.
Similarly, by identifying A-, AA-, or AAA-ranked patents, we obtain a helpful reference for validating the false-negative ones.
Let’s try to identify the major players in the AMOLED patent field. The table below, created with data collected by Patentcloud, provides an overview of the top 20 applicants:
