1 PATCOM - THOMSON REUTERS Classification needs and first experiences with CPC IPC WORKSHOP, Geneva 2013 Doina Nanu

2 CLASSIFICATION NEEDS AND FIRST EXPERIENCES WITH CPC Introduction – classification systems Is Patent Classification still needed Patent classification uses Classification challenges CPC – threat or opportunity - Conclusions

3 (TOO) MANY PATENT CLASSIFICATION SYSTEMS International Patent Classification – WIPO Cooperative Patent Classification (ECLA)– EPO/USPTO US Patent Classification (until 2015) – USPTO DECLA – German Patent and Trademark Office FI /F-Terms – Japanese Patent Office DWPI Manual Coding system Common Hybrid Classification – Global Patent Classification

4 IS PATENT CLASSIFICATION STILL NEEDED? Increasing global patent activity Classification systems require high maintenance High granularity, often dependent on national, regional technology profile Frequent updating cycles (revisions, reclassifications) Consistent classification rules often reconciled with national patent law The more refined to meet specific requirements, the higher the maintenance and, paradoxically, risk of failing Different classification systems (national, regional) Recent classification developments (CPC, CHC) - substantial projects undertaken by patent offices High interest from patent user community Patent classification has multiple applications and is useful !

5 PATENT CLASSIFICATION USES Search tool : Language independent : overcomes translation variations and terminology alternatives in emerging technologies, as well as spelling errors Suitable for Technology drill down and concept retrieval Document routing tool: In production and editorial departments patent documents are routed to technology experts In product creation : for alerts and patent profiles In Machine Translation developments where the classification is used to associate the correct technical dictionary with the respective technology

6 CLASSIFICATION CHALLENGES Classification features with limited user benefits: –Inconsistency of classification attributes (eg generating office, position, source of classification, etc.) –Insufficient details related to certain classification features, linking codes Missing classification Invalid classification Availability at publication with the rest of bibliographic data

7 MISSING/INVALID IPCs IN NEW PULICATIONS LOADED IN DWPI

8 IPC – SAME INVENTION, DIFFERENT CLASSIFICATION IPCs applied only once within family A23L 1/0522 A23L 1/09 A23L 2/00 A61K 47/14 A61K 47/26 A61K 47/36 A61K 8/97 A61Q 13/00 B01F 17/00 B01F 17/34 B01F 17/36 B01F 3/08 C08B 35/02 C08J 3/02 C08L 3/06

9 CHALLENGE MEANS OPPORTUNITY Missing and invalid IPCs – value add by assigning front end classification Inconsistent classification –DWPI Manual coding –DWPI patent family Confusing Attributes - product enhancement features eg Inventive, non-inventive, generating office, version, etc

10 CPC –THREAT OR OPPORTUNITY? Conclusions (1) Yet another classification system or chance for Integration in IPC or be the backbone for global classification? Granular, but how representative for technology developments in Japan, China, Korea? Applied to a large number of collections but not available at the time of patent document publication (except for US data, EP)

11 CPC –THREAT OR OPPORTUNITY? Conclusions (2) Concordance with IPC good for now but how will the divergence be avoided as CPC evolves If more offices join in, how will the consistency of classification be maintained? –Role of the USPTO in consolidating the success of CPC –Role of WIPO in unifying the very best of the existing systems into a global classification, consistently applied by patent offices worldwide irrespective of their size

12 Classification needs and first experiences with CPC - IPC Quality Issues - Christiane Emmerich PATCOM/FIZ Karlsruhe IPC Workshop, Geneva 2013

13 IPC Quality Issues Invalid IPCs in the DOCDB backfile Missing IPCs of new patent publications 13

14 Invalid IPCs in DOCDB 14 The IPC subgroup C12N 5/06 was transferred to C12N 5/07 plus further subgroups with IPC version IPC Revision

15 Invalid IPCs in DOCDB C12N 5/06 became invalid with IPC version records with C12N 5/06 IPC reform codes only* US7.713 JP2.476 WO2.233 EP2.230 AU1.726 CA1.484 DE981 CN877 * records in INPADOCDB with C12N 5/06 (IPC8) of which 559 provide the revised code C12N 5/07 (plus further subgroups), search week 06/2013

22 Conclusions Reclassification of the MCD backfile needs to be enhanced to ensure comprehensive retrieval when searching with the current version of the IPC WIPO should encourage smaller patent authorities to assign IPCs more extensively, e.g. IT, SG, AR PCT searching authorities should be encouraged to assign IPCs more timely to PCT documents, so that IPC could be used for monitoring purposes 22
