Who Owns All the Smart Grid Patents? New Study Reveals Answer

March 25th, 2014

Ever wonder who owns all the smart grid patents?  With all of the acquisitions in smart grid (see, e.g., here and here), it seems a lot of folks have been considering the question.

A recent study by patent analytics firm Relecura on smart grid patent holders seeks to answer this question.  It turns out the top five are ABB, GE, Panasonic, Siemens, and Toshiba:

The study breaks out the results by six sub-technology categories (communications, software, smart meters, sensors, substation automation, and distribution automation) and lists the top large entities and SMEs in each subcategory:

The full report, which can be found here, styles itself a “preliminary survey of the Smart Grid assignee landscape and first-cut identification of patent asset holders in Smart Grid technology.”

According to Relecura, the purpose of the study is to identify potential licensees and acquisitions targets for each of the sub-technologies.  The study uses 2008 as a reference year, and defines its Potential Licensees and Potential Acquisitions Targets relative to that year.

More particularly, Potential Licensees are entities whose patent applications were filed in 2008 or later while Potential Acquisitions Targets are typically small or medium sized entities with granted patents from applications filed in 2008 or earlier.  In other words, small companies and SMEs with relatively mature patent portfolios are deemed more ripe for acquisition and those with younger patent portfolios are thought to be more amenable to licensing IP.

With so much activity in smart grid M&A, this report could be useful to a lot of people.

Korean Program Seeks to Patent Smart Grid Standards

April 18th, 2013

I saw an interesting story at SmartGridNews.com about a Korean program to support patenting of standards for smart grid technologies.  Additional reports are at Energy Korea and Power Insider.

The Korea Smart Grid Association recently launched the initiative, which will support R&D projects conducted by companies, universities and research institutes to develop core technologies and standards for smart grid applications.

The program is sponsored by the Korea Intellectual Property Office (KIPO) and supervised by an organization called the Standard Patent Center.

The ultimate goal, it seems, is to generate patents that cover standards in the smart grid space.  Kim Yeon-ho, the Director General of the Electric and Electronic Burear at KIPO, was fairly blunt about Korea’s thought process on this:

The standard patent is a high value-added patent that can enjoy both market power and monopolistic strength of patent, which are advantages of standardization.

A major caveat to the monopoly power rationale is that the owners of patents covering industry standards are typically required to license the technology on terms that are fair, reasonable, and non-discriminatory (FRAND).

The Korea Smart Grid Association offers another explanation, claiming to be looking out for the little guy.  The Association’s Vice President, Mun Ho, said:

Given that most smart grid-related companies are small and mid-sized businesses, which are weak in coping with standard smart grid patents, the program is expected to signficantly contribute to strengthening their competitiveness.  The Association will exert continued effort to promote creation of patent standards.

In particular, the Association plans to develop flexible AC transmission systems and electric vehicle charging infrastructure technologies, create standard patents around those technologies, and then “provide results of development to small and mid-sized smart grid companies.”

At Smart Grid News, Jesse Berst’s “quick take” puts this patent program into context:

In the U.S., the smart grid has largely been about empowering customers and utilities with better information. In Korea, the smart grid is part of the country’s industrial policy and has been singled out as an important new export opportunity. [This program is] one of the steps the country is taking to make that plan into a reality.
