Recently, a client’s product listed for sale on Amazon US was removed from the platform on the grounds of alleged infringement of an invention patent owned by a world-renowned consumer brand. The client immediately contacted Attorney Deng, entrusting his team to analyze whether the product constituted patent infringement, and to negotiate on the client’s behalf with the patent owner regarding potential settlement and patent licensing arrangements.

After reviewing the details of the case, Attorney Deng’s team promptly conducted a thorough analysis of the client’s product against the claim terms of the asserted patent. Following an in-depth comparison, the team found that the client’s product did not fall within the scope of the asserted claims and thus did not constitute an infringement.

Based on this conclusion, Attorney Deng immediately sent a non-infringement legal opinion letter to the patent owner’s intellectual property and legal departments, demanding the immediate withdrawal of the complaint.

During the negotiation and communication process, Attorney Deng adopted a more proactive communication strategy in light of the potential litigation procedures. This strategy yielded excellent results.

The rights holder replied to the email on the very day of being contacted by Attorney Deng. After multiple rounds of communication, it acknowledged that the product indeed did not infringe on its patent on the following day. Eventually, the complaint was withdrawn promptly without any settlement costs, and the client’s Amazon listing was restored immediately. This prevented the client from suffering irreversible losses caused by the delisting during Black Friday and the year-end shopping sprees.

The swift and successful resolution of this case also highlights that Attorney Deng’s team has extensive successful experience in handling dispute resolution and negotiations pertaining to U.S. invention patent infringement matters.

When addressing the patent infringement dispute in this case, the team provided professional and accurate infringement assessment for the client’s product, delivered highly efficient responses and achieved results that exceeded the client’s expectations.
