US 9665705

A comprehensive analysis of United States Patent 9,665,705 reveals a system for biometric security access that has been the subject of administrative challenges at the U.S. Patent and Trademark Office (USPTO).

Patent Overview

• Title: Remote entry system
• Assignee: Cpc Patent Technologies Pty Ltd
• Inventor: Christopher John Burke
• Filing Date: January 19, 2016
• Issue Date: May 30, 2017
• Abstract: The patent describes a system for providing secure access to a controlled item. It comprises a database of biometric signatures and a transmitter subsystem with a biometric sensor. This subsystem matches a received biometric signal against the database to generate an "accessibility attribute." It then transmits a secure access signal, which could use a rolling code, encrypted Bluetooth™, or WiFi™ protocol. A receiver subsystem then receives this signal and grants conditional access to the controlled item based on the information in the signal.

Plain-Language Summary of Independent Claim

The patent contains one independent claim:

• Claim 1: This claim outlines a complete system for secure access. The system has three main parts: a memory to store biometric data (like fingerprints), a transmitter, and a receiver. The transmitter has a biometric sensor. When a user provides their biometric data, the transmitter's controller compares it to the stored data. If there's a match, it determines the user's access rights (an "accessibility attribute") and sends this information in a secure wireless signal to the receiver. The receiver then grants or denies access to a controlled item, such as a door lock or a computer. A unique aspect of this claim is that the same biometric sensor and controller can be used to add new users to the system. This is done by inputting a specific series of biometric signals (for example, a certain number of touches for a specific duration), which the system interprets as a command to enroll a new user.

Litigation and Administrative Review

US Patent 9,665,705 has been subject to post-grant proceedings at the USPTO. An inter partes review (IPR) was initiated by Assa Abloy AB and other petitioners (IPR2022-01006). Additionally, the patent was the subject of an ex parte reexamination request by HID Global Corporation, which led to a notable USPTO decision on April 27, 2026, regarding the timing of estoppel after an IPR final written decision.

A search of the Court of Appeals for the Federal Circuit (CAFC) dockets for 2026 did not yield any specific results for US Patent 9,665,705 in the initial investigation. This does not definitively mean no such cases exist, but none were readily apparent through broad searches. Further, more specific searches of CAFC records may be required to confirm the presence or absence of any appeals related to the aforementioned administrative proceedings.
