Litigation involving US Patent 9055254:

  1. PTAB Case IPR2024-00353

    • Plaintiff(s): Unified Patents LLC (Petitioner)

    • Defendant(s): Voice Tech Corp. (Patent Owner)

    • Jurisdiction: Patent Trial and Appeal Board (PTAB)

    • Case Number: IPR2024-00353 (This case number, as provided in the Google Patents listing, does not directly match the one found in the search results (IPR2020-01018 and CAFC 22-2163). The search results for "IPR2024-00353" did not yield specific details for patent 9055254, but rather a generic reference to "IPR2024-00353 filed (Final Written Decision)" on the Google Patents page for US9055254. However, the search results consistently refer to Voice Tech Corp. v. Unified Patents, LLC, Case No. 22-2163 (Fed. Cir. Aug. 1, 2024) and IPR2020-01018. It appears that the IPR2024-00353 listed on Google Patents may be a placeholder or a subsequent action related to IPR2020-01018 involving a different patent. Since the search results for the provided IPR number did not directly link to US9055254 but rather to another patent, I will state that the patent linked in the search results is 10,491,679, and the original request was for 9055254. I will however list the outcome for IPR2020-01018 as it was part of the provided search results to clarify why the original IPR number was not directly matched to US9055254.)

    • Filing Date: IPR2020-01018 was related to a petition for inter partes review. The specific filing date for IPR2024-00353 is not explicitly provided in the search results.

    • Outcome/Current Status: The Google Patents entry states "Final Written Decision" for IPR2024-00353. The search results related to Unified Patents IPRs (though for a different patent, US10491679) indicate that Unified Patents often petitions for IPRs and that the Board sometimes finds challenged claims unpatentable. Without specific details linking IPR2024-00353 directly to US9055254, a precise outcome cannot be given for this specific patent.

    • Clarification: The search results for "IPR2024-00353 Unified Patents" primarily refer to Voice Tech Corp. v. Unified Patents, LLC, Case No. 22-2163 (Fed. Cir. Aug. 1, 2024), which involved US Patent No. 10,491,679, not US9055254. In that case (IPR2020-01018), the PTAB found all challenged claims of US Patent No. 10,491,679 unpatentable, and the Federal Circuit affirmed this decision. The Google Patents listing for US9055254 may be generically listing an IPR filed by Unified Patents, but the specific case details for US9055254 with the number IPR2024-00353 are not available in the search results provided.

    • Case Number: 2:22-cv-00494
    • Filing Date: Not explicitly stated in the search results for this specific case number.

  4. US case filed in Court of Appeals for the Federal Circuit

    • Plaintiff(s): Not explicitly stated in the provided snippet on Google Patents or search results.
    • Defendant(s): Not explicitly stated in the provided snippet on Google Patents or search results.
    • Jurisdiction: Court of Appeals for the Federal Circuit (CAFC)
    • Case Number: 25-2039

    • Outcome/Current Status: The Google Patents listing simply states "litigation." No further details on the outcome or current status for this specific case number and patent were found in the provided search results.

Based on the available information, while Google Patents lists these cases as involving US9055254, the detailed search results for the specific case numbers, particularly for the PTAB case, directed to other patents when explicit patent numbers were mentioned in the search snippets. For the district court and other Federal Circuit cases listed by Google Patents for US9055254, the search results did not provide specific details on the parties, filing dates, or outcomes directly linked to US9055254. Therefore, I cannot provide those details with high confidence for these specific entries.Known litigation involving US patent 9055254:

    • Defendant(s): Patent Owner: Not explicitly stated in the search results for this specific case number directly linked to US9055254.

The search results for IPRs involving Unified Patents and similar numbers, such as IPR2020-01018 (which led to CAFC Case No. 22-2163), indicate Voice Tech Corp. as a patent owner, but for a different patent (US10491679), not US9055254.
