The following pertains to Sequenom, a legal case related to diagnostics that may very well wind up before the Supreme Court.

Sequenom has filed a petition for rehearing en banc, arguing that a recent panel decision was inconsistent with earlier Supreme Court, decisions, and that the panel’s decision poses a threat to patent protection in multiple fields of invention.

The case involves inventors who discovered that cell-free fetal DNA was circulating in the blood of pregnant mothers, and that this knowledge could be used to create a maternal blood test for certain fetal genetic traits and abnormalities.
