ClassClarify to examine the USPTO Manual of Classification.
ClassClarify is an electronic
edition of the USPTO Manual of Classification, the manual
used by patent examiners to classify US patents. Use ClassClarify
to help you search for prior art, look for trends and major
players in industry, and generally negotiate the complex
landscape of patent documents.
by taking a few patents of direct relevance to your search
(the first few hits from a keyword search is a nice start)
and import their class numbers into ClassClarify. Then build
up a more comprehensive list of related classes by examining
the class schedule. Expand the scope of the search by adding
parent subclasses. Examine speciation by adding child subclasses.
Notes from the subclass definitions also contain new search
ideas and classes. Export your finished class list to a
search engine or report. The software makes this process
easy and intuitive.
The Manual of Classification
is a descriptive study of the art itself, rather than a
prescriptive abstract model of the art. A careful study
of the manual using ClassClarify will reveal the nature
of what is actually being patented and how patents relate
to each other. It's an essential tool for the Examiner,
as it should be for you.
