"Patent reform" efforts in Congress, a hot topic for the last seven years, stemmed largely from concerns about excesses in patent enforcement and litigation. 1 Those efforts failed in each of the last three Congresses. Recently, the legislative sponsors cut back their enforcement-oriented proposals and the full Senate then stripped those that remained from the leading "reform" bill after hearing testimony on the remarkable developments described in this article. 2 Whatever "reform" legislation may pass both houses of the 112th Congress will do almost nothing to address the enforcement-oriented concerns that drove initial reform efforts. Nor will it make much difference to the strength or availability of U.S. patent protection or the rights of patent holders vis-a-vis infringers. 3
