How (Not) To Discourage The Unscrupulous Copyist, Peter L. Ludwig
How (Not) To Discourage The Unscrupulous Copyist, Peter L. Ludwig
Peter L. Ludwig
This short article explores how the U.S. and Japanese courts implement the doctrine of equivalence when determining patent infringement. The doctrine of equivalence is a balance of, on one hand, the public’s interest to know the metes and bounds of the patent; and on the other hand, the private interest of the patentee to be granted a sufficient scope for the granted patent. After comparing and contrasting the courts’ implementation of the doctrine, I propose a new method that places the burden on the patent practitioner, before infringement proceedings begin, to determine the proper scope of the patent.
