As I discussed in my previous articles, the industry is finally waking up to the fact that when it comes to patents, quality indeed matters much more than quantity. Also, the realization that simpleton approaches such as standards contribution counting or counting the mere number of patents doesn’t give an actual picture of technology leadership. At the same time, assessing the quality of patents has been a challenge. While the gold standard, in my view, is market-based valuation, new quality accessing metrics and methods are emerging. These are designed to consider many aspects such as how fundamental and market impacting the inventions are, how wide the reach of the patents is, how many other patents are derived from them etc. and try to come up with a quality score. I will explore many of them as part of this article series, here is the discussion on the first one on the list.

Patent Asset Index™ by LexisNexis® Patent Sight®

Patent Sight is a leading patent analytics and valuation firm, based in Germany. Its services are utilized by many leading institutions in the world, including the European Commission. Patent Sight has developed a unique methodology that considers the importance of the patent in the hierarchy of the technologies, its geographical coverage, and other parameters to provide a score called the Patent Asset Index. This index allows industry as well as general audiences to not only understand the comparative value of the patents that various companies hold but also rank them in terms of technology leadership.

Here are some of the Patent Sight charts regarding 4G and 5G patents, presented at a recent webinar hosted by Gene Quinn of IPWatchDog. During the webinar, William Mansfield of Patent Sight shared these charts. The first chart shows the number of patents filed by some of the top cellular companies between 2000 and 2018. As is evident, if only quantity was the metric, one could say that companies such as Qualcomm, Huawei, Nokia, LG, and Samsung, are far ahead of the others.


Now let’s look at the Patent Asset index chart of the same companies:

Under this assessment, the scene is vastly different. Qualcomm is still in the lead, and there is a drastic change in the ranking as well as the relative standings of others. Qualcomm is far ahead of its peers, followed by Samsung as a distant second, followed by LG, Nokia, and InterDigital. Surprisingly, Huawei, which was neck-to-neck with Qualcomm in terms of sheer number patents, is much farther behind.

Why quality vs. quantity comparisons matter?

Unquestionably patents are borne out of important innovations. However, as I have explained in this article, all patents are not created equal. Also, when it comes to cellular patents, there is a much-believed myth that Standard Essential Patents (SEPs), as the name suggests, are extremely important, and are core to the technology. However, because of 3GPP’s self-declaration policy, this designation is not as reliable as it seems and is highly susceptible to abuse. For example, companies with deep pockets that are interested in boosting their patent profile might invest large sums in developing non-core patents and declaring them as SEPs. That’s why the quality indicators such as the Patent Asset Index and other such approaches are important tools to assess the relative value of the patent portfolios. In the next articles, I will discuss other indicators and the specific parameters and the methodologies involved in the quality determination. So be on the lookout!
