Recently, Zhao Baochun, a lawyer from Zhilin Law Firm, represented a patent infringement dispute in the field of robotic vacuum cleaners. The plaintiff, Suimi Company, and the defendant, Ecovacs Company, are both leading companies in the field. The case involves four popular infringing products of Ecovacs. During the litigation process, Ecovacs filed a second round of invalidation against the involved patents after the first invalidation failed, showing obvious adversarial nature.

The case was presented with evidence, cross examined, and tried in court. The first instance court made a judgment to stop the infringement and compensate for the losses. The technical facts and technical comparison basically accepted the plaintiff's claims. In terms of compensation for losses, the first instance court basically accepted the sales data of the infringing product platform and the third-party profit percentage evidence submitted by the plaintiff, finely calculated the defendant's profit, and based on this, ruled that Ecovacs Company should compensate Xumi Company for economic losses and reasonable rights protection expenses totaling 8868517 yuan. This case is a typical controversy with high industry attention, and the judgment result has important reference value for similar intellectual property protection practices.
