Regeneron challenges Federal Circuit finding that withholding information in discovery constitutes inequitable conduct; district judge orders firm to pay Merus $10.5m in attorneys' fees and costs.

After losing patent infringement suit against Merus involving antibody-producing mouse, Regeneron fights ruling that it withheld material information in prosecuting the patent.

Insulet, developer of a fundamentally new insulin delivery system, just raised $50 million in its fifth venture round. This brings the total it's raised to date to more than $120 million, which sounds like a tremendous sum for a small device company founded just six years ago, but relative to the size of the opportunity it's really not. There are one million diabetic patients who need to inject insulin several times a day to manage their diabetes. For these patients, Insulet has brought insulin pumps into the age of iPods.

Johnson & Johnson, whose LifeScan Inc. division is number one in the $6 billion glucose monitoring industry, acquired Animas, which after Medtronic MiniMed, is the number two player in the insulin pump market. J&J gets not only a leading insulin pump business, but also technology that lends itself to the future goals of all diabetes companies; the development of an artificial pancreas, or at least, the ability to automatically deliver insulin in response to automated continuous blood glucose measurements.
