NPE / troll-pattern signals

  1. Shell-entity transfer — Not present. There are no recorded transfers of the patent to an entity with a shell-like name or known registered-agent address. The original assignee, Telcom Ventures LLC, is described as a principal investment firm specializing in venture capital and private equity, indicating a broader business purpose than just patent licensing.

  2. Known asserter in the chain — Not present. Telcom Ventures LLC is not identified as a known patent asserter (NPE) in the provided search results from RPX, Unified Patents, or other common NPE lists (Acacia Research Corp, Marathon Patent Group, Intellectual Ventures, IPNav, Wi-LAN, Mosaid / Conversant, Vringo, Pendrell, Innovatio IP Ventures, MPHJ Technology, Lumen View Technology, Round Rock Research, Document Generation Corp, Erich Spangenberg entities). Intellectual Ventures, for example, is described as a company whose business model focuses on buying patents, aggregating them, and licensing them or seeking legal damages. MPHJ Technology Investments and Innovatio IP Ventures are also noted as patent trolls for their assertion activities. Vringo engaged in worldwide patent wars and acquired numerous patent families for assertion. Round Rock Research also partnered with IPValue to acquire and license a large patent portfolio. Lumen View Technology was also identified as a patent holding "Non Practicing Entity" that acquires patents and instigates patent infringement lawsuits. Telcom Ventures LLC does not align with these descriptions.

  3. Repeat correspondent across the chain — Not present. There is only one initial assignment recorded (from inventors to the original assignee), so there is no chain of assignments to evaluate for recurring correspondents.

  4. Cascading transfers — Not present. No multiple consecutive assignments were recorded.

  5. Pre-litigation transfer — Unclear. Without a recorded litigation history for this specific patent, it is not possible to assess if any hypothetical transfer occurred prior to litigation.

  6. Bankruptcy fire-sale — Not present. There is no indication that Telcom Ventures LLC has filed for bankruptcy or that the patent was sold as part of bankruptcy proceedings.

  7. Privateering — Unclear. There are no SEC filings or other public information indicating that Telcom Ventures LLC is asserting patents on behalf of another operating company.

  8. Defensive aggregator (anti-NPE) — Not present. The current assignee is Telcom Ventures LLC, which is not identified as a defensive aggregator like RPX, Allied Security Trust (AST), LOT Network, Unified Patents, or Open Invention Network. These organizations are generally known for their efforts to mitigate patent risk and protect members from PAE litigation.

Verdict

Insufficient data
There are no recorded post-issuance assignments for US patent 9462411 in the USPTO Patent Assignment Search database. Therefore, there is insufficient data to identify any NPE/troll-pattern signals beyond the initial assignment from the inventors to Telcom Ventures LLC. The absence of recorded transfers means the patent likely remains with the original assignee.
