Create a List of Patent Holders in European Countries for a Category of Drug Patents Due to Expire in a Particular Year?
TOPIC: In this example, you want to create a list of patent assignees in European countries that have patents for anti-depressant drugs due to expire in the later half of 2005. IMS Patent Focus (File 447) monitors patent expiration dates worldwide and includes evaluated patent data from 57 countries with priority details (country, number, date) and patent application numbers by country. The therapeutic class code can be used to create a list of drug patents.
The RANK command lets you perform trend or statistical analysis on an existing search set by extracting terms from the specified field(s) in a set of records and lists them in ranked order, with the most highly posted term appearing first.
COMMAND SUMMARY
BEGIN 447
SELECT TC=N6A?
SELECT ED=20050601:20051231
SELECT S1 AND S2
SELECT S3 AND PC=(FR or ES or IT or EP)
Click S4 > Tasks > Rank
Check Patent Assignee and click OK
Check the patent assignee(s)
SELECT S4 AND S5
TYPE S6/9/1
Note: If you do not know the therapeutic class code, SELECT the therapeutic class (e.g., antidepressant?) and TYPE the resulting set using Format 6 to see the class code.
HOW TO...
1. BEGIN 447 to search a file that contains drug patent details and expiration dates worldwide.
2. SELECT the therapeutic class code for anti-depressants. Use truncation (?) to retrieve all narrower classes.
3. Use ED=YYYYMMDD for the expiration date range from June 1, 2005 to Dec. 31, 2005.
4. Use PC= to limit the search with specific patent country codes. Note that the country code EP includes the states designated in a regional EP patent, but not applications filed in individual European countries.
5. Click S4 > Tasks > Rank.
|
|
6. Click the check box for the Rank Field you want to rank, in this example, patent assignee.
|
|
7. The patent assignees in S4 will be ranked from highest to lowest number of patents that will be expiring.
Check the patent assignee(s) you want to view and click Search.
To view the records, select the format and number of items and click View.

8. Note that Set 5 (S5) contains all patents for patent assignee Wellcome.
9. Combine S5 and the set (S4) limited by date, location and code for anti-depressants.
