What should I do if I receive a letter from an intellectual property lawyer?

So what should I do as a suspected infringer after receiving a lawyer's letter or a warning letter? Based on our previous experience in handling such cases, our lawyer made the following suggestions: 1. After receiving the warning of patent infringement, you need to reply as soon as possible. If you don't reply, if you are convicted of infringement in the future, this delay may be judged as intentional infringement, so you should ask double indemnity; 2. If the warning letter doesn't specify which product infringes or which patent infringes, or he doesn't provide relevant patent documents, you can ask for these materials when you reply. 3. If the above contents are made clear in the letter, the reply should indicate that the company will attach importance to this matter, take measures to adjust the research, and avoid admitting infringement in the reply. 4. Whether the facts stated in the letter of entrusting a firm or analyzing a lawyer really involve infringement. 5. If there is no infringement, the reply can be marked as "After analysis, the company believes that there is no infringement, and this matter ends here". 6. If there is any suspected infringement, report to the boss, cross-license, or discuss the solution with the other party. Because our lawyers mainly serve in the field of intellectual property rights, they often handle such lawyer's letters for clients. According to our lawyer's experience, companies such as Microsoft, Apple, Adobe and Autodesk often send lawyer's letters to the outside world, and many Japanese companies are also very active in safeguarding rights. If an enterprise receives a lawyer's letter from a big company, it should pay attention to it and be calm. If big companies warn you through lawyers' letters, they may have some basis. Therefore, we must be cautious when dealing with it, and don't easily disclose the current situation of related enterprises to the other party, so as not to let the other party have further evidence and make the later processing more passive. On the other hand, big companies are not perfect. If the law is applied properly, small companies can also beat big companies.
