CAFC OKs JMOL When Expert Changes Testimony at Trial

Recently, the Federal Circuit issued a decision in Rembrandt Vision Technologies v. Johnson & Johnson Vision Care. The issue in the case primarily centered around whether the district court correctly granted judgment as a matter of law that J&J did not infringe claims of U.S. Patent No. 5, 712,327.

The technology at issue in the case related to contact lenses. Two important characteristics of a contact lens are its permeability to oxygen and the wettability of its surface. By the 1980s, both hard and soft contact lenses that were permeable to oxygen were well known, but these contact lens often lacked a highly wettable surface.

The contact lens claimed in the ‘327 patent had both a highly wettable surface and were permeable to oxygen. The patent disclosed a soft gas-permeable lens that contained an acrylic layer on the surface of the lens body. This acrylic layer increased the wettability and comfort of the lens.

Discovery Issues in Patent Litigation: Making the Most of the Federal Rules

The following is an excerpt from an article written by Douglas Nemec (Partner at Skadden and Practice Center Contributor), and his colleagues Hope S. Yates, Devin Kothari and Gayle Denman.

Try to imagine patent litigation without discovery.  For most of us such a thing is hard to conceive.  Aside from the rare case in which a court grants a temporary restraining order or preliminary injunction request based only on the moving papers, U.S. courts simply do not grant relief for patent infringement without first allowing some discovery.  Practitioners outside the U.S. may question whether discovery is really necessary, but that point is seldom debated in the U.S.  Rather, the ongoing debate in U.S. federal practice revolves around how to make the discovery process maximally efficient without sacrificing its very purpose – the discovery of evidence.  After all, the great struggle in every patent litigation is balancing the fact that discovery is by far the most expensive part of the process with the fact that the vast majority of cases settle during the course of discovery, as a result of facts revealed through discovery.

Reasoned debate has yielded the Federal Rules of Civil Procedure, an ever-evolving set of rules governing discovery (and all other procedure) in the U.S. district courts.  Supplementing the rules is an enormous body of case law interpreting and applying the Federal Rules, as well as other procedural rules and concepts.  The existence of the Federal Rules will not be news to any reader of this article.  Yet many of the rules are underutilized or neglected entirely, particularly in evolving areas such as electronic (e-) discovery.  Many practitioners, moreover, take a formulaic approach to discovery that saves expense in the short run but ultimately leads to inefficiency and exposes them to a plethora of dangers that advance planning and adherence to the prescriptions of the Federal Rules would otherwise eradicate.  The purpose of this article is first to propose alternatives to certain inefficient discovery practices, and second to cast new light on various procedural rules and principles that practitioners can employ to enhance the effectiveness and efficiency of discovery.
