Two databases are included: Invention and Utility Model. At least one database must be selected before searching, otherwise users will be prompted to select it. Users can select the database through the check box. Multi-selection is supported.

2. Entering Form
2.1 Publication Number
This field supports post-wildcard search and logic search. " * " stands for logic "AND", " + " stands for logic "OR", " - " stands for logic "NOT".

Example: 1270091; 12700

2.2 Publication Date
This field is a date type field and supports post-wildcard search. The word "to" is used to connect two dates (the former date should be earlier than the latter one) to indicate a search during this period. Date formats are "yyyy" or "yyyymm" or "yyyymmdd".

Example: 200001; 2000 to 2005, 20020102 to 20041011

2.3 Application Number

Example: 00102942; 001029

2.4 Application Date
This field is a date type field and supports post-wildcard search. The word "to" is used to connect two dates (the former date should be earlier than the latter one) to indicate a search during this period. Date formats are "yyyy" or "yyyymm" or "yyyymmdd".

Example: 200001; 2000 to 2005, 20020102 to 20041011

2.5 Title
This field supports fulltext search and logic search. " * " stands for logic "AND", " + " stands for logic "OR", " - " stands for logic "NOT". Bracket stands for a higher operation priority and has to appear in pairs within the expressions. A " \ " must be added before terms in order to transfer meaning manually if the search expressions contain system characters, such as " * ", " + ", " - ", " ( ", " ) ", " % ", " ? ", " \ " and " ' ". The maximum length of search expression is no more than 200 letters (including the Boolean operators). If words are separated by blanks, it will be considered as a phrase in the title.

Example: (prevention+treatment)*nicotine

The maximum length of search expression is no more than 200 letters (including the Boolean operators).

Example: pfizer; martin; pfizer*product

2.9 Inventor
This field supports fulltext search and logic search. " * " stands for logic "AND", " + " stands for logic "OR", " - " stands for logic "NOT". Bracket stands for a higher operation priority and has to appear in pairs within the expressions. A " \ " must be added before terms in order to transfer meaning manually if the search expressions contain system characters, such as " * ", " + ", " - ", " ( ", " ) ", " % ", " ? ", " \ " and " ' ". The maximum length of search expression is no more than 200 letters (including the Boolean operators).

Example: Robert; Robert*Mathew

2.10 Patent Agent
