How much Detail Is Required from Patent Owners To State A Claim for Patent Infringement?

The Federal Circuit’s opinion in Disc Disease Solutions Inc. v. VGH Solutions, Inc. et. al., handed down on May 1, 2018 may very well change the specificity that patent owners and patent attorneys provide in filing a lawsuit to enforce their intellectual property rights.  It suggests that, at least for “simple technology,” there is not much difference, if any, between the old Form 18 requirements and the Iqbal/Twombly standard. This case was an appeal of a dismissal with prejudice of the plaintiff’s case for patent infringement. The Federal Circuit determined that by specifically identifying the accused products (and attaching pictures of the products) and alleging that the accused products meet each and every element of at least one claim, the patent owner had provided fair notice of the asserted infringement.
