In 2004, I accepted the request of a Swiss pharmaceutical company. After our preliminary investigation, we found that domestic counterfeiters are very powerful and it is difficult to obtain evidence. Because the pharmaceutical industry is circulating in a specific way in China. As an intellectual property service company, it is impossible for us to approve drug dealers or pharmacies to operate such cases. After our preliminary investigation, we basically found out the ins and outs of this batch of drugs, but we could not obtain an effective and complete evidence chain. The investigation cost of this kind of case is very high, which is basically difficult for the client to accept. So, if you want to do this kind of protection. You have to be mentally prepared!
Generally, this kind of case is trans-regional, and the pharmaceutical industry is a big local profit and tax collector. Even if the evidence is successful, there is still a lot of interference to some extent. Counterfeiting enterprises are generally enterprises with formal licenses. If they are not careful, they may be bitten by snakes.
It would be better if it is a small workshop, but small workshops are generally very secretive, and the personal safety of investigators is not guaranteed!
