Untouchables: WIPO Reports on Solar’s Intangibles

January 3rd, 2018

The World Intellectual Property Organization recently released its 2017 IP report entitled “Intangible Capital in Global Value Chains.”

The report tackles several questions about the types, roles, and importance of intangible assets in global value chains.  One key question is what role intellectual property plays in generating a return on these assets.

Although much of the report deals with traditional consumer products such as coffee and smartphones, of interest to readers of this blog is the chapter on innovation in the solar photovoltaic (PV) industry and, particularly, the section on PV related patent filings.

The report notes that the number of patent filing increased from less than 2,500 in the early 2000s to over 16,000 in 2011, a reflection of the growing market demand for PV installations.  Most of those technologies originated in Japan and US until 2008, but by 2010 China had surged ahead to become the top PV patent filing economy.

The report addresses the question of China’s technological catch-up, positing that China enjoyed technology transfer by purchasing production equipment from international suppliers and cultivating skilled executives educated abroad to work for Chinese companies and teach at Chinese universities.

Another finding is that China, in particular, patents minor inventions or incremental improvements while maintaining critical innovations focusing on process as trade secrets.  From this the report concludes that process innovations “are instrumental for introducing new PV products into the market and maintaining existing ones.”

According to the report, a more detailed look at the patent filings reveals that about two thirds of patenting activity relates to cell and module technologies; silicon, ingots and wafers constituted under 10% of patent filings, and the remainder is equipment.

The report finds that the growth in PV patenting activity has reversed recently; between 2011 and 2015, the number of PV-related patent filings fell by 44 percent.  This fall has occurred in all major PV innovating countries except China.

The decrease is a result of two forces, the report concludes.  The first is a decline in the number of applicants (though the number of applications per applicant has increased), particularly in the US, Germany, Japan and Korea.  This is because many players have exited the market, and market entry is difficult.

The remaining players, however, seem to be filing more patent applications and increasing their R&D intensity.  This focus on the next generation of technologies “suggests that IP-protected knowledge assets may become more valuable in this time of sectoral recomposition.”

The second reason for the decrease is a reduction of the internationalization of PV patents.  In other words, applicants are filing in fewer countries outside their home country, opting out of international patent protection.  The report finds that in the mid-2000s, each PV invention was filed on average in three different patent offices, but by 2015, the average was only 1.5.

The report notes that PV patent applicants typically file in only a few countries/jurisdictions (China, US, Japan, Korea and Europe) and rarely file in, e.g., Australia, Russia, Latin America, Africa, and the Middle East, or anywhere else.

While most innovation studies focus exclusively on patent data, the report has an interesting section on “reputational assets” such as trademarks and brand-related activities.

The report finds that trademark protection for PV products and services has grown in the last decade.  Data from the US and international trademark application databases show that PV-related trademark filings were four to six times higher in 2016 than they were in 2005.

In the conclusion to the PV IP chapter, the report states that because PV panels and systems are now “mostly commodities rather than differentiated goods . . . the dynamics of the industry have been profoundly driven by strategies to reduce production costs, rather than by product innovation.”  In addition, the solar PV market is “saturated with an incumbent technology whose depressed prices provide tight profit margins for companies.”  Accordingly:

Firms can dedicate their R&D efforts either to high-level process innovations that will reduce production costs in the dominant technology, or to new solar PV product innovations whose production prices are below those for the incumbent technology.

With respect to China, the report calls the PV industry “a case study of a compelete form of technology transfer to an emerging economy.”

Keeping the Aisles Clear: Envision’s Parking Lot Solar Chargers Got Tracking!

February 9th, 2016

Envision logo

Envision Solar (Envision) is a San Diego-based company that makes solar parking structures that can be used to charge electric vehicles, support outdoor digital advertising, and enhance energy security.  What makes Envision’s products unique is that unlike most parking lot solar-powered vehicle charging stations, most of the company’s systems have the ability to track the movement of the sun.

According to Envision’s President and CEO Desmond Wheatley, 90% of Envision’s deployments have tracking capability.  Why tracking?  He echoed my thoughts exactly:  because it’s “cool.”

Also, parking lots are “hyper-restrained” in geography so a solar charger needs to maximize energy density in a very small space.  Incorporating tracking helps in that regard.

Envision’s two major product offerings are the Solar Tree® and the EV ARCâ„¢.  The company owns at least seven U.S. patents and pending applications covering various aspects of the technology in these products.

U.S. Patent No. 7,705,277 (‘277 Patent), issued in 2010, covers Envision’s original design.  Entitled “Sun tracking solar panels,” the ‘277 Patent is directed to a system for maximizing solar energy utilization by moving a solar panel to track movement of the sun from sunrise to sunset.  Movements of the solar panel are accomplished daily in accordance with a programmed schedule of consecutive cycles.

A subsequent patent issued in early 2014 is directed to a refined design better suited for solar tracking in a parking lot.  The system covered by U.S. Patent No. 8,648,551 (‘551 Patent) is significant, Wheatley said, because instead of the tracker causing the solar panel to swing in to the drive aisle, it instead bows.

According to the ‘551 Patent, the rotation of a cylindrical knuckle in the tracking system “allow[s] the solar panel to continuously reorient while maintaining a substantially stationary footprint.”

Wheatley told me the company’s most important intellectual property is that around the features of the EV ARCâ„¢.

Wheatley mentioned several advantageous features of the EV Arc.  First and foremost is its autonomy, i.e., it is not connected to the utility grid.  Some of the structural features are also important, including the ability for the thin base plate to support heavy vehicles and the high-traction material of the base plate, which allows it to remain stationary.

U.S. Patent No. 9,209,648, issued in November 2015, is entitled “Self-contained renewable battery charger” and is directed to a charging system (10) comprising a portable unit (12) that includes a moveable docking pad (16) having a base (18) and compartment (20) for holding a storage battery (18).

 

648 FIG 1

The portable unit (12) includes a column (24) having a first end (26) mounted onto the docking pad (16) and a second end (28).  A solar array (30) is affixed to the second end (28) of the column (24).  The unit has a structural canopy with a beam (32) and cross members (34) attached to the column (24) to support the photovoltaic modules of the solar array (30).

The company also has IP around the mobility and installation of its systems, including a specialized trailer and hydraulic ram, ARCâ„¢ Mobility, for transportation and deployment purposes.

Wheatley and Envision are very aware of the importance of patent protection in the U.S. and beyond.  The company’s patents, he said, “prevent smaller competitors from copying” their technology.  They also might stop larger customers from buying pirated products.  In general, a strong IP portfolio increases the company’s value in the investor community.

With investments of about $200 billion on EV charging, the company sees China as an important market and has filed patent applications there.  Wheatley told me that Chinese patents allow Envision to bring powerful partners aboard in China to protect the company’s business ventures there.

Envision Solar continues to innovate and isn’t stopping at car charging; they’re working on EV ARCâ„¢ eBike and eMotorcycle charging as well.  Many more patent applications will certainly follow.
