Goog day,

I met a problem, working with Petapator. When trying to search documents by IPC I always got 0 documents. I entered the class like A01N 25/16. Please, tell me if there are any particularities in entering the IPC class in Petapator?

Thank you.

Hi Irina,

Petapator does not change the query syntax at the USPTO website.  According to USPTO:

TIP: To search for International Classification G06F 19/00, you must enter the classification with a zero ("0") in place of the space -- i.e., without any embedded spaces -- as follows: ICL/G06F019/00. Formatting your search in this field in any other way will result in an error.

For example, if you want to search for IPC with G06F and all of sub-classes of G06F, you should enter ICL/G06F???/??. ? is the wildcard. Please give it a try.

If someone has other suggestions, please let is know.
