Last May, an arguably ancillary statement in the Supreme Court’s Ebay v. MercExchange ruling provided ample fodder for patent bloggers, and a warning to 'patent trolls.' As its central holding, the Court simply clarified the discretionary powers of trial courts to issue permanent injunctions for patent infringement on a case-by-case basis. In short, the Court concluded there is no presumptive eligibility for a permanent injunction against a patent infringer.
However, what really caught bloggers’ attention may have been dicta in a plurality concurrence. Wrote Justice Kennedy, “When the patented invention is but a small component of the product the [defendant] companies seek to produce and the threat of an injunction is employed simply for undue leverage in negotiations, legal damages may well be sufficient to compensate for the infringement”. Some observers read a ‘working requirement’ into this statement -- i.e., that to receive the full range of patent remedies, plaintiff must actively use the patent it seeks to enforce. This inference is consistent with growing concerns that the public is not getting the full benefit of the burden of patents on the advancement of the arts and sciences, especially in the protection of so-called business methods.
Broadly speaking, this statement might be a warning shot across the bow for opportunistic patent enforcers, disparagingly referred to as 'patent trolls.' Such companies typically do not practice ('work') their patented inventions. Rather, their business models focus on securing licensing revenue from infringing companies, often by or under the threat of (previously) presumptively automatic injunctions. Under a 'working requirement,' non-patent-practicing companies would lose substantial leverage for negotiating patent licenses.
The Court’s majority opinion should assuage these concerns to some extent, suggesting that a universally applied 'working requirement' would injure "university researchers or self-made inventors." However, it remains to be seen whether lower Courts, using their equitable powers, may selectively fold a 'working requirement' into permanent injunction analysis based on the characteristics of the litigants.
