Patent Infringement Lawsuit filed against the City of Anna Texas for Use of Guardian Background Software

December 2, 2021 – Seattle, Washington:  Rylander & Associates PC filed a federal complaint on behalf of Miller Mendel, Inc. against the City of Anna, Texas, Police Department in the United States District Court for the Eastern District of Texas alleging infringement of U.S. Patent 10,043,188 B2 (the ‘188 Patent) for a “Background Investigation Management Service”. The lawsuit alleges that the City of Anna, Texas and the Anna Police Department are infringing the ‘188 Patent through its use of the Guardian Alliance Technologies investigation software platform.

The patent infringement lawsuit filed against the City of Anna is the fourth (4th) lawsuit filed for patent infringement related to the Guardian Alliance Technologies background software. The other three patent infringement lawsuits have been filed in federal district courts of Alaska, Oklahoma and Oregon.

Miller Mendel’s Patents are Strong

In 2020, legal counsel for Guardian filed a petition for an “Inter Partes Review” (“IPR”) with the USPTO, asserting the MMI’s 10043188 patent covering certain features and functionality of the eSOPH system are invalid. The USPTO rejected Guardian’s IPR petition. Guardian appealed the USPTO’s decision and, in response, the USPTO issued another decision denying Guardian’s appeal. Guardian then filed a request for a USPTO Procedural Opinion Panel, which was also denied. On July 22, 2021, Guardian field a “Petitioner’s Request for Extension of Time” to file a Federal Circuit appeal, which the USPTO also denied. The USPTO IPR filings by Guardian were reviewed and decided by a panel of three qualified USPTO judges.

In 2021, Miller Mendel’s President and CEO drafted an open letter further discussing the patent infringement matter along with other serious, public concerns related to the Guardian background software.
