    Pruning to improve quality - an evolution in the EPO's Y-tags for the CPC. Geert Boedt and Victor Veefkind, EPO

    The Y-tags for climate change related technologies (e.g. clean energy) have been around for nearly 10 years now. … We will explain the main changes and plans for the future of the Y02/Y04S tags.

    Additional information:

    CPC Classification:
    CPC Y02/Y04S[with notes]: Y02A (Adaptation to climate change); Y02B (Buildings); Y02C (Capture and storage of greenhouse gases); Y02D (ICT aiming at the reduction of own energy use); Y02E (Production, distribution and transport of energy); Y02P (Industry and agriculture); Y02T (Transportation); Y02W (Waste and wastewater); Y04S (Smart grids)
    USPTO. OIPC/Classification Standards and Development.
    Compilation of Changes to the CPC Scheme: Y02A-Y02E, Y02P, Y02T, Y02W, Y04S. August 11, 2020 (or in a pdf file, p.107-200)

    The INPADOC classification scheme: lifting the veil over details. Sonia Kaufmann and Christian Soltmann, EPO

    …This presentation provides an overview of the detailed structure level of the INPADOC classification scheme and the current status of the classification of INPADOC legal event data on that level.

     Note: Based on results of 2018 users survey [2, 3], EPO has opted to develop “genuine” detailed structure level of INPADOC classification scheme (so named “Option C”), not based on the detailed event list of WIPO ST.27 Standard [5, Annex I] (“Option B”) [2], while of the INDADOC classification scheme categories A-M, P-Y [4, p.7-16] correspond to event categories of the WIPO ST.27 [5, 6]. EPO user’s survey [3]  includes drafts of detailed structure level of INPADOC classification scheme  for 6 of 21 categories (D,G,H, L, R and M, [3, p. 27-32]). For explanation of the detailed scheme and users search strategies in GPI based on it, see [1, p. 22-37] and [3, p. 17-22]

    A forgotten source of prior art? Understanding and searching inventor's certificates Eva Straková and Jürgen Mühl, EPO

    “..With several hundred thousands documents, [inventor's certificates from former socialist countries] are still an important source of prior art and might be relevant for novelty and invalidation searches.”  The authors would discusses “challenges in accessing these documents” and “how [to] use Espacenet to access basic information on inventor's certificates from several jurisdictions and some national sources”; “what differences between patents and inventors' rights” and “in which countries do [inventor's certificates] still exist as a major form of IP protection

    Using EPO linked open data: opportunities unveiled by the IPLOD project
    Dolores Modic, Ljubljana University
    (Presentation, 16 p.)

    … Taking Linked Open EP data from the EPO and SN SciGraph from Springer Nature, we built a new EPO LOD database-centric sub-cloud. Interlinking the data carefully enabled us to put together enriched information on research and innovation activities by individuals and linked with further databases, and to discover even more data via a user-friendly interface.

    Fighting Coronavirus - background to the EPO's response. Nigel Clarke, EPO
    (Presentation, 33 p.)

    The EPO's response [to the COVID crisis] included the creation of an online patent resource for scientific and clinical researchers, containing free-to-use targeted searches, patent statistics and downloadable datasheets. The presentation will explore some of the Fighting Coronavirus content.

    Resource details:

    EPO Fighting Coronavirus: Includes more 180 search strategies (combination of CPC codes and keywords, listed in hyperlinked Excel files below), created, as reported, by “EPO patent examiners who are experts in the technologies directed to the fight against coronavirus infections, together with [EPO] expert patent analysts” on the following areas of research:
    [1]Vaccines & Therapeutics: vaccines (10 [search strategies]), candidate therapies for coronavirus/COVID-19 (2), candidate antiviral  and  symptomatic therapeutics (61+18), nucleic acids and antibodies therapeutics (6+1);
    [2] Diagnostics: Nucleic acids and Immunological analyses (5+5), Analytical protocols (virus in samples [sampling/devices/microscopy], in-vivo [technique/devices], image processing (20+35+3);

    Lessons from searching and analysing AI-related patent, and non-patent data

    Irene Kitsara, WIPO

    In 2018, the World Intellectual Property Organization embarked on a journey into the world of in 2019. WIPO developed an AI taxonomy, built an AI search strategy, and analysed nearly 340 000 patents, over 1.5 million scientific publications related to AI, and other non-patent data. In this session, some interesting findings, AI's relationship to intellectual property, and what all these can mean for the future of people, tools and administrations.

    Discussion Rounds

    Discussion round 4  To what extent is AI learning to "understand" patents?

    The session will address three areas of patent searching and AI: unstructured text, patent figures and the problem of multiple languages

    Discussion round 5       AI implemented inventions as prior art

    ... How does one … search for technical details [of AI implemented inventions] that are difficult to explain or that are simply unavailable? Add to this the ever-expanding public domain repositories of computer generated data...

    Discussion round 6        CPC website: what do you need to avoid getting lost in the CPC information labyrinth? [to be revamp in 2021]
