Research findings: Value and usefulness of over 500 early patent citations for Expandiverse Technology

 

On November 10, 2015, when the first Expandiverse patent was issued it was already cited more than 290 times by subsequent patents. (A patent citation is a later patent, or patent application, that cites this patent or its patent application.)

Within 10 months this new technology passed the milestone of 500 patent citations. The most citations are from leading tech companies.

With over 650 patent citations today, this may become a seminal advance:

What does this mean? The average patent has just 3 to 6 citations in its 20-year life. Out of millions of patents, very few receive more than 100-200 citations.

Why is it important that there are so many citations, especially from the world’s biggest tech companies?

 

Three research studies show patent citations as an indicator of value, importance and use

Journal research into the value of millions of patent citations

According toMarket Value and Patent Citations: published in the Rand Journal of Economics:  Patent “citations indicate the extent to which those innovations turn out to be ‘important’ and hence presumably more valuable” (p. 17).

This quantitative research studied millions of patents issued over decades to 2004. It reports:

  • The mean number of citations per patent is three. (p. 32)
  • Out of millions of patents, only a few dozen patents receive over 100 citations. (p. 25)
  • Just four patents received more than 200 citations. (p. 15)
  • Firms with 20 citations and more “command a staggering 54% market value premium.” (p. 4)

Citations are a quantitative indicator of strong emerging technology:

A different kind of indicator of patent citations was calculated in Prediction of Emerging Technologies Based on Analysis of the U.S. Patent Citation Network,” published in the quantitative journal Scientometrics.

The authors said, “A predictor, called the citation vector, is defined for characterizing technological development to show how a patent cited by other patents belongs to various industrial fields. The clustering technique adopted is able to detect the new emerging recombinations, and predicts emerging new technology clusters.” (emphasis added)

For Expandiverse Technology, there are 4 clusters of patent citations:

Patent citations are the best metric for usefulness:

The value of patent citations is confirmed by Finding the Best Patents – Forward Citation Analysis Still Wins. The ROL Group’s Patent Ranking System used quantitative research to determine patent citations as the primary factor for identifying whether a patent is most useful or least useful. They explain:

“We believe that forward citations are a proxy for industry-wide R&D investment in a technology area. With more investment, there are generally more products. With more products, there is a higher chance of infringement. Infringement drives value and most likely meets a client’s needs. Specifically, a purchase either eliminates the client’s own infringement or provides a tool to use against someone else.”

The ROL Group calculated the primacy of patent citations by analyzing four relevant data:

  1. All issued patents from 2005-2014
  2. Litigated patents from the same period
  3. Patents sold by brokers from 2009-2014
  4. Patents from brokered packages of patents.

They emphasized the importance of patent citations in these two quantitative infringement metrics:

“The results were striking; the sold… patents had exponentially more forward citations… there was evidence of significantly higher forward citations in the set of litigated patents.

How do IP professionals use patent citations in their work?

Using Patent Citations as an Effective Tool While Conducting Prior Art Search describes three of the five reasons patent citations are an essential part of prior art search strategies:

Identify a technology trend:

“Patent citations are one of the best sources to track the flow of innovation in a particular field of technology… citations help in recognizing trends in technology and innovation… It is also possible to identify seminal patents by analysing patent citations, among other factors. A seminal patent covers an invention which is considered to be so important that it creates a technological shift in a particular field of technology. A patent having a relatively large number of forward citations when compared to other patents in its field may be a seminal patent.”

Assess a patent’s commercial value:

“A variety of situations may require a market value to be estimated for patents. As an example, patent valuation may be required when a patent owner is looking for investors or manufacturers, in case of company takeovers, or during the buying/licensing of patents… It is generally accepted that a patent having numerous forward citations may turn out to be more valuable when compared to patents with fewer forward citations. This is because, having many forward citations means that the technology disclosed by the patent was used by many other inventors in subsequent developmental efforts, resulting in various new innovations that have their roots in this patent, thereby increasing the value of the patent.

Freedom to operate — Mitigate infringement risks:

“Freedom to operate studies are conducted to identify patents that might have the potential of being infringed by a product/process. In case patents that may adversely impact the freedom to operate are identified… there is a likelihood that claims of such citations may also be relevant in assessing freedom to operate.”

Early global recognition of Expandiverse Technology

Many worldwide citations of Expandiverse Technology may remain to be discovered. This was learned when weekly citation reporting started recently, thanks to Steve Pearson of Pearson Strategy.

The new discovery:  Most worldwide citations are missing from the Google Patent page for the Expandiverse patent application, which lists the largest number of citations. On this page’s 500+ U.S. citations, only a small number are “WO” (international) citations.

For example, an example week’s new citations report shows the majority of new citations are outside the United States. From the April 24, 2016, weekly report:

  • Number of new citations:  7 citations
  • Number of new international citations:  4 of 7 citations
  • Major companies that cited this technology again last week:  Apple, Google, Samsung and Huawei (Chinese; world’s largest telecommunications company).

The four new international citations include:

  • Two patent filings in China:
    • Samsung Electronics Co. LTD:  CN105518616 A (20160420)
    • Huawei Tech Co. LTD:  CN105517023 A (20160420)
  • Citation in a patent filed in Europe and globally:
    • Apple Inc.:  EP3008565 A1 (20160420), WO2014/200733 (153(3)EPC)
  • Citation in a patent filed in Germany:
    • Applicants include Lockheed Corp, Deal Magic Inc., and Savi Networks LLC:  DE602010020817 D1 (20150115)

The first 6 months of weekly patent citation reports show over 60 global patent citations:

  • 61 Total worldwide patent citations (outside the USA)
  • 23 Asian patent citations
  • 22 European patent citations:
  • 10 Worldwide (PCT filings)
  • 6 Canada (other N. America)

This triggers new questions:

  • Does Expandiverse technology already have international recognition and value?
  • What is the full worldwide evidence for the value, importance and usefulness of Expandiverse Technology?
