Q: If I find someone infringing my patent, can I send a lawyer's letter to stop the infringement?

A: Under normal circumstances, a lawyer's letter can be sent to warn the infringer before formal prosecution. But if you are going to file a lawsuit against him, you need to consider whether sending a lawyer's letter will remind the infringer to give him the opportunity to hide, destroy the evidence of infringement or even transfer property; At the same time, if you send a letter not only to the infringer himself, but also to his distributor or partner, you need to consider that once the infringement lawsuit is not established, the sender may bear the losses caused by spam. Therefore, in general, we suggest that before sending a lawyer's letter, we must not send a letter for the sake of sending a letter, but make a comprehensive plan and analysis.
