Searching Chemical Names
PatSeer has chemical names indexed in a fashion that makes the search 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 characters such as hyphen ( - ) , parentheses ( { [ ) } ], slash ( / or \ ), 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 an exact match query and remove all above characters.
Let's take a couple of examples 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).
