Test the technical chronology
We established that drawings in the submitted documentation had been produced with software that did not exist on the documents’ stated date.
Case study · Russia · Patents
We overturned an invalidation based on unreliable competitor documents and restored patent protection for an anti-corrosion product used in the oil industry.
The obstacle
A competitor challenged the client’s patent, alleging that an identical device had been openly used before the filing date. The objection relied on technical documents said to evidence earlier manufacture and supply.
Although the materials contained serious inconsistencies, the Chamber for Patent Disputes invalidated the patent and stated that verifying falsification was outside Rospatent’s competence.
Our strategy
We tested the competitor’s documents technically, verified third-party markings and moved the authenticity issue into judicial review.
We established that drawings in the submitted documentation had been produced with software that did not exist on the documents’ stated date.
The relevant standardisation and metrology centre confirmed that it had never applied the marks appearing on the competitor’s materials.
We challenged the invalidation before the Court for Intellectual Property Rights and directly relied on the unreliability of the underlying evidence.
The court ordered Rospatent to reconsider the objection. On reconsideration, the patent was recognised as remaining in force.
Result
The client retained its exclusive patent position and the commercial monopoly supporting a product in demand in the oil industry.
Key point
A prior-use allegation is only as strong as the evidence supporting it. Technical chronology and independent verification exposed the weakness in the competitor’s case.
