Santa Ana, CA – A patent infringement lawsuit was filed by patent attorneys for Gem Certification & Assurance Lab (“GCAL”) at the Federal District Court in Santa Ana, accusing GemEx of infringing U.S. Patent No. 5,983,238 (“the ‘238 patent”). The ‘238 patent, entitled “Gemstone Identification Tracking and Recovery System,” was issued by the U.S. Patent & Trademark Office on November 9, 1999. The complaint alleges that GemEx uses a system for tracking gemstones that infringes one or more claims of the ‘238 patent.
The ‘238 patent generally relates to a central computer database that stores relevant information about a purchased gemstone, including the purchaser’s information, the quality of the gemstone – especially diamonds, and a unique identification number laser etched into the stone that can be used to identify a stolen or lost gemstone to aid with the recovery of the same. The database can then be accessed by third parties, such as the police or jewelry dealers, to determine if a particular diamond or gemstone has been reported as lost or stolen. The case is titled Gem Certification & Assurance Lab, Inc. v. GemEx Systems, Inc., SACV 08-700 JVS (C.D. Cal. 2008).
