- Important part of the
literature of applied chemistry
- Major source of new
technological information; often overlooked
- Particularly important for
students heading for industrial careers
- Patent is a legal document
Show a patent with obscure language - get students to guess what the
e.g. Patent A Device to vertically oscillate participants
Most chemical patents cover composition of matter or processes
- Structure of a patent
- Compare sections of a
journal article and a patent
- Claims are what is
legally protected by the patent

contain the new chemical information
Example: Pass out a few sample patents (obtain via
interlibrary loan if necessary)
Use a local company or faculty member
Contrast between very detailed and very brief patents
Contrast patents with many claims vs. only one or two.
