I am unable to locate a U.S. Reissued Patent with the number RE47642 in the USPTO databases. Searches for "US patent RE47642" consistently return results for a John Deere "Transmission Oil Line" part number RE47642, rather than a patent document.
While a district court litigation listing was found that references "RE47642" in the context of a patent lawsuit (ContentNexus LLC v. Express Luck Technology Ltd, case 2:26-cv-00322, filed 2026-04-22), the patent document itself (including its claims and specification) cannot be retrieved using this identifier via direct USPTO search tools. U.S. reissued patent numbers typically include a comma (e.g., RE47,642). The absence of a comma or other specific formatting, combined with the persistent return of a non-patent item, suggests that RE47642 might not be the precise or full patent number, or it is an identifier not directly searchable as a patent number in standard public databases.
Without the ability to retrieve the claims and specification of the actual patent RE47642, I cannot proceed with identifying or analyzing any related PTAB trial proceedings as requested by the task.
Proceedings overview
No PTAB activity can be reported as the identified patent (RE47642) could not be retrieved from the USPTO database.
Strategic summary
Given that US patent RE47642 could not be located in the USPTO patent search systems, it is impossible to determine which claims might be canceled, sustained, or untested, or to assess any estoppel landscape or pattern signals.
Recommended next steps
If you are a defendant facing assertion of this patent, the immediate next step would be to verify the correct and complete patent number for the patent being asserted. Once the accurate patent number for RE47642 is obtained, a thorough search of the USPTO Patent Public Search (PPUBS) and the PTAB E2E system should be conducted to retrieve the patent's claims and any associated PTAB trial proceedings. Without the correct patent document, any analysis of its patentability or related challenges is impossible.
