Radio-frequency identification technology specialist Neology Inc. said that it has added two patents to its most recent lawsuit against Illinois-based Federal Signal Corp. and related companies. The original lawsuit was filed in May 2012 in the Central District of California of the U.S. District Court.

Neology, which has a portfolio of 140 patents, stated that it now asserts that Federal Signal has infringed on four patents in California.

In Delaware, the San Diego-based company has filed another case that alleges that Federal Signal Corp. has infringed on six patents.

According to the company, the lawsuit demands that Federal Signal and related companies “immediately and permanently stop directly or indirectly making, using, selling or offering for sale, importing or exporting, all infringing RFID tags, readers, and systems or sub-systems.”

Neology’s RFID technology is used for border control, vehicle registration, high-value pharmaceutical control, electronic toll collection and passports, according to the company.
