What should I do if I infringe the design patent?

See if you infringe others' appearance patent right or others infringe yours. If an enterprise infringes another person's appearance patent right, it depends on whether the enterprise has reasonable defense reasons, such as invalid defense, prior use defense, legal source defense, or existing technology defense. If there is a reasonable defense, the accused infringer can be exempted from compensation. If someone infringes the patent right of the enterprise's design, then the enterprise needs to collect evidence, and then decide whether to send a lawyer's letter or directly sue the other party. No matter whether others infringe on the patent right of design or the enterprise itself, it is necessary to make a patent evaluation report on the patent right of design first, and then hire professionals to make a comparative analysis of the infringement between the infringing product and the design on the design certificate to determine whether the infringing product belongs to the protection scope of the design patent.
