Case Overview
The Parties
⚖️ Plaintiff
Non-practicing entity (NPE) engaged in patent assertion, holding and licensing intellectual property, targeting cybersecurity technology deployed in enterprise environments.
🛡️ Defendant
Publicly traded Canadian technology company with a well-established enterprise security portfolio, offering AI-driven endpoint protection through its Cylance division.
The Patent at Issue
At the center of this dispute is U.S. Patent No. 7,523,497 (Application No. US10/841,064), a patent covering technology in the enterprise cybersecurity domain. The ‘497 patent reflects innovations related to security systems and access controls applicable to enterprise environments.

The Verdict & Legal Analysis
Outcome
The case concluded via a joint stipulation of dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii), signed by both parties. The key structural terms of the dismissal are:
- • Plaintiff’s claims dismissed WITH PREJUDICE as to the asserted patent (U.S. Patent No. 7,523,497)
- • Defendant’s counterclaims dismissed WITHOUT PREJUDICE
- • Each party bears its own costs, expenses, and attorneys’ fees
No damages award or injunctive relief was granted. The specific financial terms of any underlying settlement agreement were not disclosed in the public record.
Key Legal Issues
The infringement action was resolved without a final adjudication on the merits. A with-prejudice dismissal of the plaintiff’s claims — while leaving the defendant’s counterclaims dismissible without prejudice — is a structurally significant outcome. It means PacSec3 cannot reassert U.S. Patent No. 7,523,497 against BlackBerry in any future action, and BlackBerry’s counterclaims were preserved without prejudice. This case illustrates a well-established dynamic in NPE litigation: prolonged defense by a sophisticated defendant can exhaust an assertion entity’s litigation runway, particularly when represented by major national counsel.
