Motorola annulment action thrown out of court

Motorola has lost in a crucial stage of a patent infringement lawsuit brought by laser and electronics company LPKF.

LPKF alleged that Motorola had infringed its patent for laser direct structuring (LDS), but Motorola had sought to annul the European patent.

LDS is used to manufacture antennas in cell phones and other electronics devices. In 2013, China declared the patent invalid.

In 2014, LPKF secured a preliminary ruling at the Mannheim Regional Court, in which Motorola was enjoined from selling phones in Germany that infringed the patent.

The German Federal Court of Justice rejected the annulment action, confirming the validity of the patent.

LPKF says that the ruling has allowed it to “feel strengthened” in its proceedings against Motorola.

LPKF CEO Ingo Bretthauer said: “We are absolutely determined to bring these proceedings to a successful conclusion.”

“Although we do not have great expectations for our LDS business in the short term, we will protect the LDS patent and proceed against patent infringers with all our available means.”
