Court Dismisses Java Infringement Claims against Samsung

Case Filed: Dec 09, 2010

Case Closed: Sep 17, 2013

Court: California Northern District Court

Judge: Ronald M. Whyte

Case Summary:
Nazomi Communications filed suit against Samsung for infringing their Java programming patents. HTC, LG and Kyocera are other defendants named in this suit. Nazomi was founded in 1998 and offers multimedia application processor solutions to mobile phone and semiconductor makers. The company provides Java acceleration solutions for information appliances. It has also filed lawsuits against Amazon, Microsoft, Nokia, Garmin, Sling, and others for patent infringement.

The patents involved in this suit are:

  • US7080362 entitled ‘Java virtual machine hardware for RISC and CISC processors’, legally issued on Jul 18, 2006
  • US7225436 entitled ‘Java hardware accelerator using microcode engine’ legally issued on May 29, 2007
  • US6338160 entitled ‘Constant pool reference resolution method’ legally issued on Jan 08, 2002
All the patents expire[*] by Dec 08, 2018 and are currently assigned[†] to Nazomi Communications (source: MaxVal’s Assignment Database).

The complaint said that Samsung, LG, Kyocera and HTC manufacture consumer electronic devices containing processor cores capable of Java hardware acceleration that use a virtual machine. The accused products (mobile phones) include Instinct s30 (SPH-M810), Captivate (SGH-1897), Droid Incredible, LX370, Ally (VS740), PRO-700 and Zio (M6000) respectively. The complaint also stated that “the infringement by defendants of the patents has injured and will cause irreparable injury and damage in the future unless defendants are enjoined from infringing the patents.”

In Aug, the Judge ruled that defendants did not infringe the claims asserted in the suit and granted the defendants’ motion for a summary judgment of non-infringement. On Sep 12, the Court rendered its final verdict and entered judgment in favor of defendants and against plaintiff Nazomi Communications.
