Siemens filed the rehearing request in response to a February ruling that Enzo's patent application covering its nucleic acid signal amplification technology predates and invalidates a patent owned by Siemens and relating to its branched DNA diagnostic systems.

Enzo said that a USPTO board had denied Siemens' request for a rehearing in proceedings that favored Enzo's patent on direct detection of nucleic acid.

The decision paves the way for Enzo to be issued a patent based on its prior application, and the company plans to "rapidly" develop and market products based on the technology for a wide variety of applications.

The patent office was aiming to determine who invented technology first related to nucleic acid signal amplification.
