Hot cause - accelerate energy storage technology development

  • The rate of battery improvement has slowed down to 3-5% per year. 1, 2, 3
  • Why do batteries improve more slowly than other technologies?
  • Batteries consist of several components that are manufactured by different organisations.

    Battery interfaces

    With increasing energy density, these components exhibit rising interdependencies, which means that only very few high energy material combinations will lead to stable battery cycling.
  • To come up with inventive breakthroughs, battery researchers need to achieve high situational awareness to identify suitable combinations of high energy battery components that lead to strong performance.

Cool solution - identification of highly relevant patents

  • What are the advantages of machine learning based relevancy scoring over classical keyword searches?

  • If a keyword search is comprehensive, it will typically generate a chronological list of several hundred entries that take a long time to analyse. If a keyword search generates few results, important patents will likely be missed.
  • With our machine learning algorithm, queries with hundreds or thousands of results can be ordered according to relevancy scores generated by a curated machine learning model, as defined by a subject matter expert.
  • Curated machine learning models allow for superior insight and situational awareness, because enterprise-specific search results can be projected against a range of technical fields with which the user may be less familiar, leading to a ranked list with the most relevant patents at the top.
  • Relevancy scores are calculated based on titles, abstracts, IPC classifications as well as applicant information.

  • Machine translation of patent titles, abstracts and applicants

  • Less than 40% of patent documents that were newly added to our database from January to June 2017 initially contained an English title and abstract. These patents are mainly submitted to patent offices in China, Japan, Korea, Germany & France in the corresponding national languages.
  • If a newly added patent in our database does not contain a family member with English title/abstract/applicants, machine translated English title/abstract/applicants are automatically added to the database.
  • This function substantially increases situational awareness, as Non-English energy storage patents are finally searchable with our offering.
  • For some but not all non-English patents, the European Patent Office (EPO) adds a translation approximately 4 months after publication. If this is the case, we replace the machine translated version with the EPO version.
  • Tailored patent searches & analyses to support strategic decisions

  • As a result of our unique capability to identify the most relevant patents related to a specific subject matter along with substantial energy storage market know-how, strategic decision makers and patent lawyers have been very satisfied with our tailored studies.
  • What is the source of patent information provided by

  • Our database currently consists of more than 1.4 Mio. patent documents from the European Patent Office (EPO) database, published in 1990 or later, that either contain the words 'battery' or 'batteries' in the title or abstract, or to which CPC or IPC1-8 patent classification codes H01M (batteries & fuel cells) or H01G (capacitors) were assigned.
  • The EPO database contains patent documents filed with 90 countries and WIPO (World Intellectual Property Organisation).
  • Every patent listing contains a link to the EPO website where the full text can be accessed.

Cool solution - facilitate collaboration between researchers

  • Users can offer and request battery components and services based on standardised technology transfer contracts on our free collaboration platform.
  • Collaboration requests are included in patent reports, making sure your request reaches an audience of researchers with the relevant interests.
  • Material Transfer Agreement (MTA)

  • Materials can be exchanged based on the material transfer agreement (MTA) for chemicals published by the association of university technology managers (AUTM). This standard MTA is recommended for materials exchanges between non-profit organisations.
  • The standard MTA by is proposed for cases in which publication of electrochemical data in scientific journals and exchange of confidential data are the main focus of the collaboration. It allows for filing of intellectual property rights only if all collaborators agree and mandates that patent ownership is based on inventorship. If the filing of intellectual property rights is the focus of a collaboration, options are to use the open development agreement (ODA) or to negotiate a proprietary joint development agreement (JDA) that regulates intellectual property rights.
  • Open Development Agreement (ODA)

  • The open development agreement (ODA) by is an attractive option for all organisations who are primarily interested in defensive protection for their intellectual property and in 'freedom to operate' for their customers. According to the ODA, open patents can be used by any organisation involved in energy storage research, but their use incurs a number of obligations, including reporting the use of any open patent to the organisation that filed it, prohibition of reverse-engineering and of the assertion of intellectual property rights against the organisation that filed for the open patent. Donations for the use of an open patent from a non-profit organisation are encouraged, but remain volontary.
  • Non-Disclosure Agreement (NDA)

  • The standard non-disclosure agreement (NDA) published by regulates the exchange of confidential information. It is helpful to provide a legal framework during the initial phase of a collaboration, before materials are exchanged.
  • Discussions or material exchanges can also be initiated without a signed legal agreement. We think this is usually suitable only if non-hazardous, widely available materials are exchanged.
  • We welcome any comments regarding these standard agreements, which will be very helpful for the definition of improved versions:
