Option: DCR searches can also be refined 

using a series of DCR Number Roles 

• DCR Number Roles help describe the context of 

an indexed compound within the patent, e.g. 

– compound is prepared, purified or part of a mixture 

– compound is claimed or from the examples 

• Use the (T)-Term proximity operator to refine 

DCR searches DCR Number Roles 

– For example: => S L2 /DCR (T) PRD/DCR 

– Where PRD = the Produced (synthesized) Role 

See HELP ROLES in <strong>DWPI</strong> on STN (file WPINDEX/WPIDS/WPIX) for 

more information on effective searching using DCR Number Roles. 

Example: refine the search with Roles 

=> S L2/DCR(T)PRD/DCR

Hands-on Practice 

SUBJECT SEARCHING 

1. What did you have for breakfast this morning? Choose one item of 

food or drink and search for patents on that subject. Take a look at 

a selection of titles (compare SCAN, TRIAL, SUM and simply TI) 

and display one database record in full (compare formats MAX, 

ALL, IALL, FULL, IFULL) and one in a bibliographic format 

(compare BIB, IBIB, FAM). [SEE PAGES 15 & 19] 

2. Search for patents on fireworks. How many of these relate 

specifically to rockets? Extract those records which contain 

images (=> S Lx AND GI/FA). Display some of the images online 

(ALLG, FULLG or simply GI). Print some records to email. Type 

HELP PRINT if you need instructions on how to use the PRINT 

command. [SEE PAGES 15-19] 

3. There have been many inventions dealing with earthquake 

resistant building components. Gather these together and display 

a few records in a format which includes patent assignees and 

patent numbers. (Hint: <strong>DWPI</strong> Classes Q44 and Q45 will make your 

search easier.) [SEE PAGES 15 & 20-21] 

4. Use <strong>DWPI</strong> Class D25 to search for patents concerned with 

detergents, then use ANALYZE to find out which companies have 

applied for the greatest number of patents in this area. (You will 

probably retrieve a very large number of records; to save time, do 

not ANALYZE all of them!) [SEE PAGES 20-21, 25-28 & 36-37] 

73


5. Over the years, numerous people have come up with novel ideas 

for dual-purpose convertible traveling or camping accessories (for 

instance a waterproof jacket that can be converted into a sleeping 

bag). Trying to find all these inventions using keywords would be 

virtually impossible because there are so many possibilities - but 

the IPC leads us straight to the answer. Search the following IPCs 

using the correct search format and display titles (TI) and IPCs 

(IPC) from a few of the resulting records. [SEE PAGES 23-24] 

A 41 D 15/04 Garments convertible into other articles 

A 45 F 4 Travel or camping articles which may be 

converted into articles for other use 

6. EPI MANUAL CODES: Carry out a keyword search for illuminated 

clock faces and hands. Use SELECT or ANALYZE to check which 

Manual Codes (MC) are most applicable in this subject area then, 

using these Manual Codes, try to find further relevant patents. 

(Suitable Manual Codes include S04-A02X which covers the 

illumination of mechanical clocks and watches – and S04-B04 - for 

electronic displays.) [SEE PAGES 20-21] 

7. CPI MANUAL CODES: Carry out a keyword search for artificial 

joints and limbs. Compare your result with the number of records 

retrieved in a search using Manual Code D09-C01D. Why are the 

results so different? [SEE PAGES 20-21] 

8. Extend the search from Question 3 to include <strong>DWPI</strong> original titles, 

abstracts and main claims (/BIEX). How many additional records 

are found? [SEE PAGE 18-19] 

9. EP714631 describes a lancet for taking blood samples. Use the 

citations given in PCI to find patents on the same or similar topics. 

(TIP: search the patent in PN field of file DPCI, SELECT the 

cited/citing patents - PN.D, PN.G - from the record retrieved, return 

to file WPINDEX and search the E-numbered items in the PN field. 

Display the records retrieved. Could the same result be achieved 

using Accession Numbers?) [SEE PAGE 64] 

74


BIBLIOGRAPHIC SEARCHING 

10. Somebody has invented a cat flap (a small door-within-a-door for 

a domestic cat to enter and leave a house) that distinguishes 

between black and ginger cats. Find the appropriate record in 

<strong>DWPI</strong> and display it in the most cost effective format which will 

enable you to read an abstract. What else can this invention be 

used for? What is the name of the patent assignee? Does he 

have any other patents? [SEE PAGES 19 & 29-30] 

11. A number of years ago Kodak Clinical Diagnostics applied for a 

patent relating to the diagnosis of Alzheimer's disease. In which 

countries did they seek protection? [SEE PAGES 19 & 25-28] 

12. Retrieve all the patents applied for by De Beers. (Hint: use 

EXPAND to display all the company names beginning "De 

Beers..." then identify the correct PACO by using the Patent 

Assignee Code Thesaurus.) In which country is their patenting 

activity concentrated? Conduct an analysis using SELECT or 

ANALYZE on various country fields to find the most commonly 

occurring patent country or designated state. Which country 

codes give the most meaningful information? [SEE PAGES 25-28] 

13. Retrieve all of Toshiba KK basic patent applications published 

between 1990 and 1992 (inclusive). Identify those which do not 

have a Japanese priority. Which is the most common priority 

country for these applications? [SEE PAGES 25-28 & 42-45] 

14. From which country did ES 8605209 originate? How much time 

elapsed between the date of this first application and the date of 

publication of the first family member? [SEE PAGE 31] 

75


15. How many PCT applications (country code WO) were published 

in 1991? How many of these designated Germany? How many 

of these records have a German (DE) patent family member? 

(TIP: to display designated states use PI) [SEE PAGE 35] 

16. Search for patents on the Japanese delicacy sushi. Exclude from 

your search all patent and patent applications which have only 

been published in Japan. (Hint: use the country count CYC or 

patent number count PNC fields.) How many of the remaining 

records have a Japanese priority? [SEE PAGES 35 & 42-45] 

17. Search for Japanese number 38211, from 1984. This might be 

an application number, a Kokai or Kokoku publication number. 

Search for all three possibilities. [SEE PAGE 35 & 42-45] 

18. Using keywords combined with <strong>DWPI</strong> Class W04, retrieve all the 

inventions relating to music CDs. Isolate those which have been 

patented by Sony. With which other companies does Sony share 

the patent rights? (Hint: rather than displaying all the records, 

use ANALYZE to get an overview of the names or codes 

appearing in the patent assignee field.) [SEE PAGES 20-21 & 36] 

19. Use ANALYZE on <strong>DWPI</strong> Classification (DC) and IPC subclass 

(SCL) to find out about Zebra Co Ltd products. Display the 

results in delimited (DELIM) format. [SEE PAGES 20-21 & 36]
