PASADENA, Calif.–(BUSINESS WIRE)–RealDefense LLC, a leader in embedded consumer cybersecurity and privacy solutions, today announced that the United States Patent and Trademark Office has granted U.S. Patent No. 12,609,908, titled “Selectively Blocking Connection Requests to Ensure Privacy.” The patent, issued April 21, 2026, protects a kernel-level method for identifying and blocking the tracking scripts that quietly collect personal data from consumers as they browse the web.
“Consumer privacy has been quietly eroding for years, and the tools people relied on to protect themselves are being phased out one by one,” said Gary Guseinov, CEO of RealDefense. “This patent recognizes a fundamentally different approach.”
