There are different classification systems adopted by various countries:
International Patent Classification (IPC) – This is most common system
Cooperative Patent Classification (CPC)
International Classification for Industrial Designs (Locarno Classification)
United States Patent ClassificationNote : - From 2015, USPTO no longer actively assign USPC to utility patents. Plant and design patents will continue to be published with USPC symbols. - Now uses Cooperative Patent Classification (CPC)
For more information, refer to Patent Libguide (under Classifications, Codes & Glossary, Etc.)

Approaches to Searching Patents
18
Topic Search
- Start broadly…. using Synonyms, Truncations, wildcards variations, - Refine with additional keywords, classification numbers, etc.
Single Document Search
- Start with a known patent document- Find other patents with patents using
relevant classification numbers, citations analysis, references (including non patent literature), etc.
Semantic Search- Using text or patent
number
Classification Search

How the patents are organized:- “patent analysis algorithms to create what is essentially a self-
organising map”- “Similar patents are positioned closer together, and different patents
are spaced further apart”- “the mountains, where patents will be clustered, represent areas of
high activity and the low lying areas represent lower levels of patent activity”
- Clusters based classification codes and semantic analysis of keywords (title/abstracts)
