Article by Dr. Kathryn Paisner, PhD
Director of Research, Analytics, and Business Development

Wearable electronics have been ballyhooed by many as the next truly revolutionary “smart technology.” Integrated into clothing, accessories, and other personal devices, these networks of sensors linked to tiny portable computers are uniquely positioned to harvest next-generation health and behavioral data from their human hosts.

Unlike smart phones, which may be casually relegated to desks and charging stations while their users sit at home or work, wearable electronics continuously monitor consumers’ activities, heart rates, and emotions, for the entire duration of their use. Doctors and medical researchers believe that this data could vastly improve patient outcomes, and marketing professionals are practically salivating at the wealth of behavioral information that may be used for increasingly individualized advertising campaigns.

Currently limited to an array of relatively clunky—yet increasingly stylish—devices, the future of wearable electronics may ultimately depend on groundbreaking research in battery technology. Apparel-based devices, for example, should optimally stretch and bend with their users, but although printed circuit technology offers some solutions for sensor and computing components, suitable batteries remain a significant challenge.

Many researchers have achieved a high degree of flexibility in their batteries, but stretchable cells are still largely the stuff of the future. It is difficult to maintain sufficient cell density while simultaneously creating a high degree of elasticity in the battery itself.  Collaborative research from the University of Ilinois at Urbana-Champaign and Northwestern University has yielded encouraging results, and promising developments have also been reported by groups at Stanford and CUNY.

Using its advanced battery research database, the ABC PatentEdge™, IP Checkups also identified a handful of other organizations that appear to have focused research efforts on stretchable batteries. As is common with early stage technologies, universities and other public research institutes feature prominently in the space; however, some private companies—large and small—have also invested resources in this area.

Patent Activity by Top Companies

Table 2. Patenting activity by top organizations. The number of patents filed by each group, in each calendar year, is shown in the table below.

In addition to identifying organizations with interest in stretchable batteries, the ABC PatentEdge also offered some insight into the aspects of stretchable battery technology on which these groups primarily focus. Polymer-based separators are the most common area of interest, and over 50% of patents relating to stretchable batteries discuss at least one innovation in separator or electrolyte technology.

IP Checkups is proud to be working with both NAATBatt and CalCharge to accelerate the development and adoption of advanced energy storage technologies.

IP Checkups developed the ABC PatentEdge™ with input from experienced battery technology experts, representing eight key member organizations of the National Alliance for Advanced Technology Batteries (“NAATBatt”). NATTBatt is a not for profit trade organization of foreign and domestic corporations, associations and research institutions focused on the manufacture of large format advanced batteries for use in transportation and large scale energy storage applications in the United States. Members include advanced battery and electrode manufacturers, materials suppliers, vehicle makers, electric utilities, equipment vendors, service providers, universities and national laboratories. NAATBatt’s core missions are to grow the North American market for products incorporating advanced energy storage technology and reduce the cost of those products to U.S. consumers.

Over the past several quarters, IP Checkups has been delivering exclusive ABC PatentEdge quarterly updates to NAATBatt member companies.

“NAATBatt is excited to be partnered with IP Checkups. We believe the ABC PatentEdge provides advanced battery and capacitor companies, investors, and research institutions with critical insight into emerging technologies, trends, and opportunities in advanced energy storage markets,” said James Greenberger, Executive Director, National Alliance for Advanced Technology Batteries.

IP Checkups has also developed a strong partnership with CalCharge, a groundbreaking public-private partnership working to accelerate the development, commercialization, and adoption of new energy storage technologies for the consumer, transportation, and grid markets. On Tuesday, July 22, IP Checkups is hosting an introductory webinar on the Advanced Battery & Capacitor PatentEdge at 12 PM PST for CalCharge members. If you are a Calcharge member or would like to find out more about the webinar or becoming a CalCharge member, please contact Chris Mohajer for access to the webinar.

By establishing strong partnerships with trailblazing organizations such as NAATBatt and CalCharge, IP Checkups is proud to support and accelerate innovation in the green technology space. The ABC PatentEdge is critical to providing innovative battery and capacitor companies with access to important insights into technology ownership and technology development information so they can continue to focus on creating novel and innovative technologies.

“New Entrants” are companies that have started filing patents related to graphite anode technology for the first time between July 2009 – June 2014. The New Entrants sample report was developed using data from the ABC PatentEdge database, which houses more than 200,000 worldwide battery-related patents. We have added more than 11,000 patents to the ABC PatentEdge, from worldwide patent authorities in 2014 alone. Our patent-centric solution is the only way to stay on top of new developments in the advanced battery industry.  Order your New Entrants report today and discover who else is developing innovative technology besides the big corporations.

Below is a list of the top new entities in batteries that filed patents in the last five years but were overall new to the space.  Additional patent information such as region and inventor are available with ABC PatentEdge subscriptions.

BERKELEY, CA (July 16, 2014) We are excited to announce the launch of our Advanced Battery & Capacitor (ABC) PatentEdge Blog, a place where IP Checkups’ battery patent experts will post analyses on advanced battery companies, technologies and innovation trends.  The blog will cover a wide range of patent-focused topics including a look into who is filing patents related to next generation lithium-air technology, what materials are being considered for future nickel metal hydride batteries (NiMH), which new entrants are working on graphite anode technology, which key inventors are working on new batteries and ultracapacitors for electric, hybrid, and fuel cell vehicles, and many more.

Flexible batteries anyone? Stay tuned…Kathryn Paisner, our resident PhD patent analyst and chemist, will post an in-depth analysis on stretchable batteries later this month!
