IV. CASE STUDIES
In this Part, several patent applications will be examined in detail in order to point out flaws in the patenting system and explain why such patents were issued in the first place. The patents are described in order of increasing comprehensibility within the framework of accepted scientific principles. Part IV.A examines a virtually unintelligible patent issued for what amounts to a dowsing rod. Part IV.B examines a slightly more sophisticated patent granted to a free energy device (that is, a perpetual motion machine). Part IV.C discusses the cold fusion patent cases arising from a very sophisticated group of cold fusion scientists. Finally, Part IV.D examines a patent based on solid scientific principles whose claims were mistakenly assumed to be incredible by the examiner.

of the patent, may be a portmanteau of the phrase “an electrokinetic effect due to dielectrophoresis.” Id. cols.1-2.
