Inventors

  • Kelly D. Phillipps, employer likely CloudVu, Inc. / PurePredictive Inc. at the time of filing.
  • Richard W. Wellman, employer likely CloudVu, Inc. / PurePredictive Inc. at the time of filing.
    The inventors assigned their interest to CloudVu, Inc. on the same day the application was filed, which is a standard practice and does not indicate unusual departure patterns.

Original assignee

The entity named on the issued patent is PurePredictive Inc. At the time of the patent application and issuance, PurePredictive Inc (initially incorporated as CloudVu, Inc.) was a software company focused on predictive analytics, aiming to provide user-friendly machine learning solutions for businesses. It is plausible they shipped products embodying the claims, as the patent relates directly to their core business. PurePredictive Inc appears to be inactive or dissolved, having assigned its patent portfolio to Web3ai Technologies LLC in November 2024.

NPE / troll-pattern signals

  1. Shell-entity transfer — Present. The patent was transferred from PurePredictive Inc to WEB3AI TECHNOLOGIES, LLC. Unified Patents identifies Web3ai Technologies LLC as a Delaware LLC formed in August 2024, acquiring patents from PurePredictive in November 2024, and its address on IPR filings is a registered-agent service (Corporation Service Company, Wilmington DE). Reel 066329/0329, executed 2024-11-25 / recorded 2024-11-27.
  2. Known asserter in the chain — Present. Web3ai Technologies LLC is listed by Unified Patents as an asserter, involved in an IPR case (IPR2026-00223) and as a plaintiff in multiple district court litigations (e.g., 2:25-cv-00260 and 1:25-cv-00757). Reel 066329/0329, executed 2024-11-25 / recorded 2024-11-27.
  3. Repeat correspondent across the chain — Present. VENABLE LLP served as correspondent for the initial assignment from inventors (Reel 030043/0088, executed 2013-05-29 / recorded 2013-06-26) and the subsequent change of name (Reel 031737/0748, executed 2014-01-09 / recorded 2014-01-09). The correspondent for the transfer to Web3ai Technologies LLC was Phillip T Chau (Reel 066329/0329, executed 2024-11-25 / recorded 2024-11-27), who is known as a frequent correspondent for NPEs.
  4. Cascading transfers — Not present. There was a significant gap between the original assignee (PurePredictive Inc) acquiring the patent (via corporate name change) and the transfer to Web3ai Technologies LLC in November 2024.
  5. Pre-litigation transfer — Present. The assignment to Web3ai Technologies LLC was executed on 2024-11-25 and recorded on 2024-11-27. Unified Patents indicates that litigation involving this patent (e.g., 2:25-cv-00260, 1:25-cv-00757) was filed in 2025, which is within six months of the assignment date. Reel 066329/0329.
  6. Bankruptcy fire-sale — Not present. There is no indication that PurePredictive Inc underwent bankruptcy proceedings prior to the assignment to Web3ai Technologies LLC.
  7. Privateering — Unclear. While PurePredictive Inc appears to be inactive after the transfer, there is no explicit public information to confirm whether they retain an interest in the assertion of this patent through Web3ai Technologies LLC.
  8. Defensive aggregator (anti-NPE) — Not present. The current assignee, Web3ai Technologies LLC, is an asserter, not a defensive aggregator.

Verdict

NPE — high confidence
This verdict is supported by multiple strong signals: the transfer to a known asserter (Web3ai Technologies LLC, identified by Unified Patents), the nature of Web3ai as a shell entity (Delaware LLC with a registered agent address, no discernible products), and the pre-litigation timing of the transfer within months of infringement suits being filed. The involvement of a correspondent known for NPE work (Phillip T Chau) further reinforces this conclusion.
