Patent Search Help
Here you can perform advanced searches of the USPTO's database
using a simple form. Achieve the specificity of Boolean
searching without using a complex syntax. Enter search
terms box corresponding to fields you want to search.
Acceptable formats include:
-
Single words,
e.g. lasers
-
Phrases in double
quotes, e.g. "laser angioplasty"
-
Boolean phrases,
e.g. laser or ophthalmoscope
Acceptable
Boolean terms are:
-
and - laser and
fiber will retrieve only fields containing both
the word "laser" and also the word "fiber"
-
or - the phrase
"laser or fiber" will find patents that contain
either "laser", "fiber" or both.
-
not - "laser
not fiber" will find all patents that include "laser"
in the field you specify, but then it will exclude all
patents where "fiber" is in the searched field.
-
andnot - this
term is interchangeable with "not".
Wild card searching is permitted:
- use "*" for multiple letters, and "?"
for 0-1 letters.
-
"electron*"
finds electron, electrons, electronic, electronics, .
. .; but "electron?" finds only electron and
electrons (omit the double quotes from your entry.)
-
wild cards inside
double quotes are not acceptable.
Notes:
-
You can copy
the results of the search result directly into PatPDF.
-
Capitalization
is ignored.
-
In the examples
provided for each searchable term, pay attention to which
examples include double quotes, and which don't.
