1 SEARCHING DWPI POLYMER INDEXING ON NEW STN BRIAN LARNER IP & SCIENCE THOMSON REUTERS JIM BROWN SENIOR KEY ACCOUNT MANAGER - FIZ KARLSRUHE 19 th November 2015
2 AGENDA Introduction to DWPI Polymer Indexing Enhanced Polymer Indexing Benefits of using Polymer Indexing Coverage of Polymer Indexing Linking of codes Manual coding of Polymers Indexing of Polymers in DCR 2
3 POLYMER INDEXING SYSTEMS IN DWPI Enhanced Polymer Indexing The most comprehensive system Only available to CPI subscribers Commenced in 1993 Prior to that the older Plasdoc coding system was used Manual codes Based on information in DWPI abstract only Focused on broadest concepts in patent only Derwent Chemistry Resource (DCR) More restrictive coverage Accessible by Non-CPI subscribers
4 CPI SECTIONS A B C D E F G H J K L M Polymers & plastics Pharmaceuticals Agrochemicals Food, detergents, water treatment, biotechnology General chemicals Textiles & paper Printing, coating & photographic Petroleum Chemical Engineering Nucleonics, explosives & protection Refractories, glass, ceramics cement & electro(in)organics Metallurgy 4
5 ENHANCED POLYMER INDEXING Deep indexing system covering all important polymer related information from the patent both generic and specific concepts are indexed Indexing contains information not present in the Derwent online abstract generates unique hits compared to text searching, IPC s etc. 5
6 WHY USE POLYMER INDEXING [1] The enhanced Polymer Indexing system was created in conjunction with the main users of the product It is the system they said would meet their needs for searching polymer related patent information Searching Polymer Indexing allows you to make use of our subject experts analysis and understanding of the patent The analyst will read through the patent document and identify what the key polymer related concepts are and apply the relevant codes So unlike keyword searching you don t get hits based on trivial references to a concept or cases where it says in the patent anything except that concept For example searching on the word polyethylene would give you a hit on a patent which stated it used any polyolefin other than polyethylene 6
7 WHY USE POLYMER INDEXING [2] The polymer indexing system utilises a unique code linking system to ensure you only get hits when concepts which are directly related are mentioned so you get a more focused answer set with little or no noise For instance with most systems a patent talking about an item of clothing made out of polyester wrapped in a polypropylene sheet would simply code the 4 concepts, polypropylene, polyester, sheet & clothing Polymer indexing codes clothing linked to polyester & sheet linked to polypropylene so you would not get a hit on a patent about a polyester sheet or polypropylene clothing 7
8 HELP IS AVAILABLE Thomson Reuters search services can help you create suitable search strategies utilizing polymer indexing For occasional queries you can also contact our help desk who can help you draw up a search strategy 8
9 ENHANCED POLYMER INDEXING SYSTEM Replaced Plasdoc Coding Coverage starts from update Both old and new indexing available from update to Enhanced Polymer Indexing ONLY from update to date 9
10 INFORMATION INDEXED All polymer related information is indexed from: patent claims DWPI documentation abstract claims related example 10
11 STRUCTURAL INFORMATION INDEXED CODE FORMAT Polymer Formers (Rnnnnn, Gnnnn) i.e. monomers and condensants Polymer Types (Pnnnn) Modified Polymers (Mnnnn) Natural Polymers (Rnnnnn, Gnnnn) Chemicals (Rnnnnn, Gnnnn) Modifying Agents (Rnnnnn, Gnnnn) Chemical Aspects (Dnn, Dnnn, Enn, Fnn, Fnnn) i.e. chemical fragment codes 11
12 NON-STRUCTURAL INFORMATION INDEXED CODE FORMAT Novelty Descriptors Universal Terms Polymer Descriptors e.g. thermoplastic, graft copolymer Shape & Form e.g. fibre, powder, foam Additive Type Catalyst Type (NDnn) (Knnnn) (Hnnnn) (Snnnn) (Annn) (Cnnn) 12
13 NON-STRUCTURAL INFORMATION INDEXED CODE FORMAT Chemical Processes Physical Operations Equipment Properties Polymer Applications (Lnnnn) (Nnnnn) (Jnnnn) (Bnnnn) (Qnnnn) 13
14 NOT COVERED Starting materials and intermediates for polymer formers and additives Chemical processes for catalyst production Generic or Markush Modifying Agents Starting materials, chemical processes, intermediates, or catalysts for modifying agent production Compounds present which are not additives, catalysts or modifying agents for the polymer e.g. a cosmetic containing vitamin E and carboxymethylcellulose 14
15 SPECIFIC COMPOUND NUMBERS - SCN Common fully defined compounds have their own codes - SCNs code format: Rnnnnn e.g. R sodium acrylate All polymer formers are indexed either by SCNs or generic codes (Gnnnn) As each SCN has a corresponding DCR number this is auto-posted in the polymer indexing This means you can search on the DCR number instead of the SCN if you wish 15
16 HIERARCHICAL STRUCTURE OF CODES Polymer Formers G0022 Monoolefinic... G0260 NT Acrylics monoolefinic G0271 NT Acrylic acids monoolefinic Including Salts thereof G0282 NT Acrylic acid + salts Monoolefinic only R00446 NT Acrylc acid R24001 NT Sodium acrylate R24000 NT Potassium acrylate G0293 NT Acrylic acid salt, other NT - Narrower Term 16
17 AUTO-POSTING In addition to the codes chosen by the indexer, the online record contains related codes that are automatically indexed Two types of auto-posting: Up-posting all broader codes further up the hierarchy from the indexed code are automatically indexed Cross-posting related codes from other hierarchies are additionally indexed Benefit - easy generic searching 17
18 UP-POSTING Additives A566 Surfactant... A624 NT Dispersant (+ A566 auto-posted) A635 NT Emulsifier (+ A566, A624 auto-posted) A646 NT Protective colloid (+ A566, A624 auto-posted) 18
19 CROSS-POSTING R24001 Sodium Acrylate CH2=CHCOONa All relevant chemical aspect codes are auto-posted: D01 Organic D26 Acrylic unsaturated chain (96) D12 Unsaturated chain D10 Aliphatic chain D53 Monoolefinic unsaturation D51 Unsaturation containing D58 Terminal olefinic unsaturation D61 Salt/Complex D83 Carbon Count F36 Monocarboxylic acid (salt) F35 Carboxylic acid (salt) Na Sodium 1A Group 1A 19
20 LINKING [1] Related codes are indexed together in distinct online sub-fields Three different types of sub-field are used, each level of sub-field is searchable with an online proximity operator three 'levels of linking', referred to as level 1, level 2 and level 3 Related codes can be searched together in the way that they were indexed, maximising accuracy and minimising noise 20
21 LINKING [2] Each separate polymer concept is linked to its associated terms (additives, catalysts, properties, applications etc.) to form a LINKING GROUP There may be several linking groups in the online record Each linking group is separated from the other linking groups 21
22 LINKING [3] Example 1 - A patent describing a new bottle made from polyethylene terephthalate and having a cap made from polyolefin e.g. polypropylene or ethylene copolymer. This patent has two polymer concepts (bottle and cap) and so would be indexed as two linking groups. Example 2 - A patent for a new tri-layer film, the outermost layer is heat resistant polyamide, the middle layer is aluminium and the inner layer is impermeable PVC. Again this patent has two polymer concepts (outer layer and inner layer), so two linking groups would be made. 22
23 LINKING [4] All codes within a linking group are linked together at LEVEL 3 LEVEL 1 and LEVEL 2 linking are used to indicate closely related codes within the linking group e.g. 'graft copolymer' linked to 'acrylonitrile' and 'butadiene' To search for codes from different linking groups the AND operator must be used 23
24 THREE LEVELS OF LINKING Level 3 - Widest level - Linking group links related substances e.g. polymer with additive(s) links polymer with properties and applications Level 2 - Middle level - Indexing 'paragraph' for each substance links a compound with its function or shape & form links co-monomers in a copolymer Level 1 - Tightest level - Indexing 'sentence' linking Chemical Aspect codes 24
25 LINKING GROUP EXAMPLE Polymer composition styrene-maleic anhydride binary copolymer calcium carbonate filler zinc stearate lubricant granulation into a powder Linking diagram to help visualise the linking levels Format for the online record what the indexing looks like online 25

39 ADDITION POLYMERS All addition polymers have monomer-based indexing, e.g. polymethylmethacrylate: (R00479 (2) H0000) i.e. methylmethacrylate + homopolymer ethylene propylene copolymer: (R00326 (2) R00964 (2) H0022) i.e. ethylene + propylene + binary copolymer For ease of searching, common polymers are also searchable as a single code, e.g. polymethylmethacrylate: P0113 ethylene-propylene copolymer: P
40 40 40
41 CONDENSATION POLYMERS Monomers/condensants are only indexed when stated in the patent, e.g. polyethyleneterephthalate from ethylene glycol and terephthalic acid is indexed as: (P0884 (2) R00822 (2) R00702 (2) H0022) i.e. PET + ethylene glycol + terephthalic acid + binary copolymer PET with no further information is indexed P0884 only for all references to PET, just search P
42 42 42
43 CONDENSATION POLYMERS When no polymer formers are stated, the polymers are indexed as a structural repeat unit (SRU), e.g. O O O O n Indexed as (P1978 (1) D01 (1) D14 (1) D19 (1) D32 (1) D76 (1) D50 (1) D93 (1) E21 (1) F90) i.e. polyester polymer type code + chemical aspects for the repeat unit 43
44 44 44
45 CONDENSATION POLYMERS If polymer formers are stated, these are indexed e.g. if the polymer from the previous slide is prepared from terephthalic acid and 1,4- cyclohexane diol, the indexing is: (P1978 (2) R00702 (2) (G1069 (1) D01 (1) D14 (1) D31 (1) D76 (1) D50 (1) D86 (1) F28) (2) H0022) i.e. polyester polymer type + terephthalic acid + (other diol + chemical aspects for cyclohexane diol) + binary copolymer For complete retrieval, search both SRU and monomer based indexing 45
46 46 46
47 SEARCHING FOR ADDITIVES Additives can be searched by chemical composition by function Boric Acid heat stabiliser R01894 (2) A511 47
48 SEARCHING FOR CATALYSTS Catalysts can be searched: by chemical composition by type by function Potassium persulphate free radical initiator R01737 (2) C088 48
49 BUILDING SEARCH STRATEGIES [1] Create separate search statements for each component for polymeric components for non-polymeric components Combine the statements together with the appropriate proximity operators 49
50 BUILDING STRATEGIES [2] Suspension copolymerisation of vinyl chloride and an alphaolefin using a dispersant and an azo catalyst Polymer: R00338 (2) G0033 (2) H0022 (2) L2675 Additive: A624 Catalyst: F13 (2) C293 Combine statements together: L1 (3) L2 (3) L3 50
51 51 Derwent Polymer tips on new STN Put L- (chemical process) and Q- (use) codes in double quotes for searching For this example, search L2675 as L2675 DCR hit structures for monomers and-or specific compounds (R-codes) are automatically included in DWPI detailed displays - Under Related DCR-Structures 51

60 TIPS FOR SEARCHING POLYMER MANUAL CODES [1] Common polymers such as polyethylene, nylons, polyesters & polyurethanes have different codes for different invention types Production Fabrication Uses Treatment Compositions Common Condensation polymers may also be classified according to the condensants they are formed from
61 TIPS FOR SEARCHING POLYMER MANUAL CODES [2] A09 property codes are only applied when that property is of exceptional importance Properties resulting from the presence of functional additives are not coded here but the additive is coded in A08 Properties that are a result of polymer structure are coded here Synthetic polymers used in pharmaceutical & agrochemical patents also code in Section B04-C & C04-C respectively Polysaccharides used in pharmaceutical & agrochemical patents also code in Section B04-C & C04-C respectively
62 POLYMERS IN DCR Around 340 common polymers have their own DCR records which are cited whenever that substance is mentioned in a patent indexed in CPI sections B, C or E This has been done since 1999/2000 The records can be found by searching for the polymer in the chemical name field This should include any common synonyms or trade names Search on polymers in the substance descriptor (/SD) field should pull up the full list
