When a former supplier turns into a plaintiff, it’s a threat to your entire production line. 

In a recent high-stakes case, our client faced an aggressive patent infringement suit. 

A former supplier hijacked a patent and claimed RMB 10M in damages. 24 units of mission-critical equipment, worth hundreds of millions of RMB, faced an immediate injunction. Previous invalidation attempts had failed, and the court was proceeding with an on-site inspection. 

How Jiaquan IP Law turned the tide:

1. 1）Our team unearthed a critical "hidden" German prior-art patent that had been completely overlooked in previous searches. 
   
2. 2）We built a dual-track defense, combining a rigorous non-infringement argument with a new, evidence-backed invalidation challenge. Based on our new evidence, CNIPA declared the patent invalid in full. 
   

The Outcome:

The plaintiff voluntarily withdrew all claims. Beyond clearing the RMB 10M liability, we secured the client’s core operations and received high praise from the presiding judge for the professional rigor of our non-infringement defense. 

At Jiaquan IP Law, we believe decision-grade clarity matters more than case detail. We don't just manage litigation; we safeguard your business continuity.
