Free practice opinion refers to the opinion that an enterprise can freely implement by asking a patent lawyer to analyze whether there is infringement risk before developing or listing a specific product. According to this opinion, judge whether it is necessary to adjust the research and development direction, redesign the product or obtain the authorization of the right holder.
Usually, what free practice opinions need to do is patent licensing research, that is, patent licensing investigation, and query the distribution of existing technologies to determine the patents that free practice opinions need to analyze.
Summary: For patent infringement, it should be noted that infringing others' patents and whether you own patents are two different issues. Implementing free patents does not mean not infringing others' patents. Therefore, it is necessary to pay attention to making products, whether it is patent clearance investigation or free implementation. The earlier you get involved, the smaller the loss.
