Approaches to Searching Patents
13
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
Further Analysis

Patent Analysis
Ms Loh Mee LanNUS Libraries
25
Patent Analysis
26
- Broad overview of the technology- Identify trends- Who are the major companies/
institutions
Remember!!Patent analysis forms part of the overall analysis about the market/technology
Combine with business information, current affairs, non patent literature, etc. to get a more accurate view.

Patsnap Landscape Maps
Ms Loh Mee LanNUS Libraries
28
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)
