How Multi-Source Date Verification of NPL Strengthened a High-Stakes Litigation

Value Delivered

A strong legal argument was built in high-profile litigation by finding multiple pre-dated references in non-patent literature (NPL). These well-documented chronological records reinforced the case’s credibility, making the prior art more defensible and strengthening the legal position. This systematic approach turned an uncertain reference into a compelling asset for the proceedings.

Problem Solved

The VAS 6430 (Vehicle Sensor Calibration System) was identified as relevant prior art. However, the real challenge was proving it existed before the cut-off date—an essential factor in high-stakes litigation. Many documents referenced the system, but none included a clear publication date. Therefore, its use as prior art in court remained uncertain without a verified timeline.

Solutions Offered

A multi-source verification approach was used to confirm the timeline of VAS 6430. Various sources were examined to gather date-based evidence, including:

  • Web Archive records to retrieve historical snapshots of web content.
  • Official company websites to track product releases and technical documents.
  • Digital publishing platforms to find any earlier references to the system.

By cross-referencing these sources, a clear and verifiable timeline was established. This strong evidence helped confirm the system’s existence before the critical date, making it more defensible in court.
