When is it a good idea to buy a patent or utility model?
There are several situations where it would be a good idea to buy a patent or utility model from another company or owner of a patent or utility model. For example, it could be to be able to fully exploit your current production. If you need access to a particular patent or utility model for your production, it can be an advantage to buy the relevant patent from another company (which of course must be willing to sell). There may also be situations where you want to avoid using resources on developing something that has already been developed by others. In this case, buying a patent or a utility model will save you money as you wont be spending time and money on research and developing something which has already been invented.
