2008 State of Software Patents
Here's the study's 2-paragraph abstract, quoted in full:
On the economic front, there continue to be billions of dollars in litigation over software patents every year, and such suits are increasingly against companies in the general economy who have software patent liability simply because they have a web site. Several pro-software patent academics have searched the existing data for evidence that software patents foster innovation, and failed to find any.
On the legal front, the courts have begun to take notice, and from the Patent Office to the Supreme Court, judges have begun to indicate a desire to revise the current policy that everything is patentable subject matter. Expect to see the restoration of many important limits on what may be patented.
This study was published before the in re Bilski decision, which indeed restored important limits to the patentability of software.
Cost estimation: US$11.2b
The following the analysis described in the paper, Klemens estimates "$11.26 billion in costs incurred by software patent lawsuits." per year. This estimate is for the total amount paid by companies to holders of software patents.
Even non-software businesses are targets
The paper discusses the suit that Global Patent Holdings (later bought by Acacia) brought against, among others: CDW Corp., Motorola, the Green Bay Packers, OfficeMax, Caterpillar, Kraft Foods, ADT Security Services, AutoNation, Florida Crystals Corp., HearUSA, Tire Kingdom, and Boca Raton Resort and Club.
