The Patents County Court has been deciding "small" patent cases for the past 20 years. Under Hon. Colin Birss, the court now limits claims to £500,000. Larger claims can be brought in the High Court. In the US, all patent infringement cases are heard in Federal District court. And, it ordinarily does not make much sense to file a patent lawsuit when there is less than $1,000,000 at stake.
Over the next year, the USPTO and perhaps other agencies will be holding hearings on whether the US should develop a small claims proceeding for lower-value patent enforcement actions. In a recent release, the USPTO has asked for input on whether this type of enforcement proceeding would have market value and, if created, what parameters should guide its implementation.
Among the information of interest to the USPTO is whether there is a need and desire for this type of proceeding, in what circumstances is this proceeding needed if such a need exists, and what features this proceeding should possess. In particular the USPTO seeks information about core characteristics of a patent small claims proceeding including characteristics such as subject matter jurisdiction, venue, case management, appellate review, available remedies, and conformity with the U.S. constitutional framework (e.g. 7th Amendment).
