Searching chemical names within patent text in PatSeer
Share:
Searching through complex chemical names especially compounds written in IUPAC nomenclature can be daunting. PatSeer has these chemical names indexed in a fashion that makes the process simpler for you. You only need to keep a one key rule in mind to form your queries for chemical name searches:
- In PatSeer character such as hyphen – , parentheses ( { [ ) } ], apostrophe/quotes ‘ ” and comma , are indexed as space and consecutive spaces are reduced to a single space
So all you have to do is put down the name or a portion of it within a phrase search query and remove all above characters.
Lets take a couple of examples of to understand this.
| Chemical name to search | Search syntax for exact match | Search syntax to match variations |
| (2,3-TRANS)-TETRAHYDRO-2-PHENYL-5- HYDROXY-3-HYDROXYMETHYLFURAN | TAC: (2 3 TRANS TETRAHYDRO 2 PHENYL 5 HYDROXY 3 HYDROXYMETHYLFURAN) | TAC:(2 3 trans tetrahydro* 2 phenyl 5 hydroxy 3 hydroxymethyl*) |
| 6(R)-[2-[8(S)(2,2-dimethylbutyryloxy)-2(S) | TAC: (6 R 2 8 S 2 2 dimethylbutyryloxy 2 S) | TAC: (6 r 2 8 s 2 2 dimethylbut* 2 s) |
| 3,4,6-TRIDEOXY-3-(DIMETHYLAMINO-ß-D-XYLO-HEXOPYRANOSYL | TAC: (3 4 6 TRIDEOXY 3 DIMETHYLAMINO ß D XYLO HEXOPYRANOSYL) | TAC: (3 4 6 trideoxy 3 dimethylamino* ß d xylo hexopyr*) |
In the search syntax we have assumed you are searching within Title, Abstract and Claims. In order to match all name variations from a portion simply use a wildcard to truncate it as shown above in the last column. For example TAC:(6 R 2 8 S 2 2 dimethylbut* 2 S) will also match 6(R)-(2-(8(S)(2,2-DIMETHYLBUTRYLOXY)-2(S) in addition to 6(R)-[2-[8(S)(2,2-dimethylbutyryloxy)-2(S).
NOTE: This post was updated to reflect some changes in syntax that went in the August’2013 release of PatSeer. For more details users can refer to the Syntax Changes section in your User manual.
