Patent 8064202

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.

NPE / troll-pattern signals

  1. Shell-entity transfer — Not present. The only recorded assignment is from the inventors to Monolithic Power Systems, Inc., which is an operating company.
  2. Known asserter in the chain — Not present. Monolithic Power Systems, Inc. is not identified as a known NPE.
  3. Repeat correspondent across the chain — Not present. There is only one recorded assignment with one correspondent, KENYON & KENYON LLP.
  4. Cascading transfers — Not present. Only one assignment is recorded.
  5. Pre-litigation transfer — Unclear. While the patent indicates "Family has litigation" and a "US case filed in Delaware District Court", the specific dates of any litigation are not available to compare against assignment dates. Given there is only one assignment from the inventors to the operating company, it is unlikely to be a pre-litigation transfer to an NPE.
  6. Bankruptcy fire-sale — Not present. Monolithic Power Systems, Inc. is an active operating company.
  7. Privateering — Not present. There is no evidence of Monolithic Power Systems, Inc. transferring this patent to an NPE to assert on their behalf.
  8. Defensive aggregator (anti-NPE) — Not present. The patent remains with the original operating assignee.

Verdict

Operating-company assertion. The only recorded assignment is the initial transfer from the inventors to Monolithic Power Systems, Inc. on 2010-02-26 (Reel 024000/0903). Monolithic Power Systems, Inc. is an active operating company that manufactures and sells products related to the patent's subject matter. The noted litigation, therefore, appears to be an assertion by the operating company.
