One of the best IP courses I took was Chemical Patent Practice from Patent Resources Group. The course notes were extensive and thorough in terms of case law, but not, of course, in the chemistry itself. I still recommend PRG's courses, though they are expensive.
Other resources to consider include:
- Chem. patent searching--Wiki page at the Univ. of Indiana
- PatentWatch at the American Chemical Society
- Derwent, major source of chemical databases for searching
- CAS.org--includes SciFinder, an excellent search tool
- PatBase.com, with good tools for chemical patents
I list a few of my own chemical patents on my biographical information page.
