NPE / troll-pattern signals

  1. Shell-entity transferNot present. Ownership of the patent remains with AQ Corporation, an operating company. The transaction with WYE IP CAPITAL LLC was a security agreement, not a transfer of title.
  2. Known asserter in the chainPresent. WYE IP CAPITAL LLC, the entity with a security interest in the patent, is identified as a Patent Assertion Entity (PAE)/NPE by Unified Patents.
  3. Repeat correspondent across the chainNot present. Both recorded assignments list "NO CORRESPONDENT".
  4. Cascading transfersNot present. There has been only one recorded assignment of ownership (from inventors to AQ Corp) and one security agreement.
  5. Pre-litigation transferPresent. Infringement litigation was filed in 2025 in the Texas Eastern District Court. The security agreement with WYE IP CAPITAL LLC was executed on 2025-09-25 and recorded on 2025-09-27 (Reel 065586/0337), indicating a financial arrangement concerning the patent close to the initiation of litigation.
  6. Bankruptcy fire-saleNot present. There is no indication that AQ Corporation has filed for bankruptcy.
  7. PrivateeringPresent. AQ Corporation is an operating company. The involvement of WYE IP CAPITAL LLC, a known NPE, through a security agreement entered into around the time litigation commenced, suggests a potential privateering arrangement where the NPE handles assertion, possibly on behalf of or with financial involvement from AQ Corporation, without an outright transfer of ownership.
  8. Defensive aggregator (anti-NPE)Not present. The chain does not terminate at a known defensive aggregator; instead, a known NPE holds a security interest.

Verdict

NPE — high confidence

The involvement of WYE IP CAPITAL LLC, a known Patent Assertion Entity (PAE), through a security agreement (Reel 065586/0337) concurrent with the filing of infringement litigation in 2025, strongly indicates an NPE assertion strategy. While the operating company, AQ Corporation, retains ownership, the timing and nature of the security agreement with an NPE suggest a coordinated effort to assert the patent.
